5.Write a Slicer
One of the key steps in processing an STL file for printing is slicing. STL files were written
...
s were written to make slicing a low memory task by storing each triangle at a single place.
We already have code to do the following:
A Generator that returns a triangle one at a time from an STL file (specifically an ASCII STL file). It Return the triangle as a list of 3D points (tuples), ignoring the normal. (from HW4)
A function that takes a list of line segments, each line segment is a list of 2D points (tuples) and returns a single list of 2D points where the start of one segment is the end of another. ( from HW 3)
A function that converts a list of 2D points to G-Code (lab 2)
A function that writes GCode to a file
To make a slicer you need to:
Write a function that calculates the intersection of a triangle with a horizontal plane. The input of the function should be a list of 3D points (tuples). It should return a list of 3D points. See this website for hints on the mathematics http://geomalgorithms.com/a06-_intersect-2.html#Triangle-Plane (Links to an external site.)
( https://web.archive.org/web/20180706054857/http://geomalgorithms.com/a06-_intersect-2.html (Links to an external site.) )
Next you need to combine all of these different functions into a single workflow that takes in an STL file, a slicing height, print temperatures, movement speed , and extrusion speed and returns a G-code String which prints the walls of the STL file. It should have an outer iteration over slice heights of the STL, for each slice height, it should scan all triangles and make a list of the line segments that intersect the plane at that Z height. Then it should order those segments into a list of points. That list of points is then converted into gcode movement and extrusion commands. The entire system combines these slices with setup and shutdown Gcode for the ender 3 printer to make the print job. You may write to a file a layer at a time or at the end.
Once the slicer is done:
Run the previous function with a vase file such as one of the following files:
https://www.thingiverse.com/thing:126567/files
https://www.thingiverse.com/thing:42570/files
https://www.thingiverse.com/thing:31722/files
https://www.thingiverse.com/thing:2795194/files
Submit your code as a Jupiter notebook with the .gcode in it and, and an image of your print.

Review of Violet Evergarden:1/13 episodes
The story of
...
he story of Violet Evergarden, written by Kana Akatsuki, takes its viewers through a story of tragedy, hardship, and community of a recovering solder in thirteen episodes. The provided series shows the difficulties and challenges soldiers encounter when returning home after the Great War, much like World War I. One character, Violet, is a young female soldier who recently returned from war. In the past, she was utilized as a fighting machine raised for that purpose, and that purpose only. She had no emotions throughout her drafted time and did not understand people deeply. Following her service, she gained employment as an auto memory doll, much like a typographer. From this employment, she regained the use of her emotions through mentorships and friendships. This resulted in her becoming a highly requested person in her field.
Violet was a child soldier in the Great War and was raised to fight and die for her cause. She was relieved of active duty following her hospitalization after her aquatint, Mr, Hodgin’s pulled some strings to have her discharged. Hodgin’s assisted Violet in finding a job due to his respect for his past friend and her mentor, Major Gilbert. She finally settles on becoming an auto memory doll, someone who writes for others. From her years of being a soldier, violet had become numb to her emotions. Because of the need for an auto memory doll to understand the client’s emotions, she thought this would be a good area of employment. While working as an auto memory doll for a foreign diplomat, she suffered a great loss of both of her prosthetic arms during an attack. While recovering, Violet learned of the prior death of her mentor Major Gilbert. At this time, she falls into a state of denial and has difficulty accepting this news.it is with the support of a friend that she can accept his death and move forward in her life and become a highly recommended person in her field. After experiencing all of these tragedies, she can regain her emotions.
Kana Akatsuki uses Violet to exhibit the worst-case scenario of the experiences of a soldier coming back from war. This is exemplified by her being a child soldier and the loss of her arms in action. These experiences resulted in her losing her emotions. Ms. Akatsuki’s portrayals of soldiers struggling with the aftermath of war are vividly explained. The mental problems and stress of losing one’s arms would cause one a great deal of distress, with having to relearn how to live one’s daily life.
In episode one, Violet awakes in the hospital after a battle that costs her arms. I could only assume what uncertainty was coursing through her mind due to becoming reliant on others. How does one previously trained to be self-reliant now become dependent upon others? Even though she has been groomed out of emotions, she would undoubtedly feel despair. In episodes two through seven, Violet has a difficult time adjusting to civilian life. His work offers her the opportunity to grow through communication with others, resulting in new friendships. Upon learning of Major Gilbert’s death in episode eight, I feel that Violet expresses raw emotion for the first time in the series. Now understanding what loss is, Violet has a whole new outlook on life. She takes further job assignments, but she has a different tone in her writing as she expresses greater compassion towards others.
During episodes eleven through thirteen, Violet gets thrown back into her life as a soldier. Because of her new understanding of emotions, she refuses to kill others to prevent inflicting that pain upon others. This was the first sign, in my opinion, that she was thinking about her actions and the effects they would have on other characters’ lives. For example, if she kills this character, his family will go through the same pain she did when she learned that Gilbert had died. This is a true sign of compassion. In episode 13, Violet attends an air show where she writes a letter to the Major explaining all she had learned. He wanted most for her to be a normal girl, and she expressed in the letter how she had done that. I feel like this is where she shows just how much she has grown personally and how she has adjusted to her new life.
Ms. Akatsuki uses a great deal of symbolism to give the viewer a clear and decisive point of view into Violet’s life. At the beginning of the story, Ms. Akatsuki gave the viewers just enough information about Violet without spoiling the whole story. She slowly eases the viewers into the plot to allow just how difficult Violet’s life is, to truly sink into the mind of the audience. Throughout the show, the viewer becomes familiar with different characters, both young and old. I believe that Ms. Akatsuki took the time to match the voice actors with their characters. For example, the voice of Violet sounds like she is very unsure of herself while at the same time having a disciplined tone. Major Gilbert's voice actor has a kind and heartwarming tone. He sounds like someone who truly was invested in others’ well-being, someone who would take Violet in. The other characters follow these examples no matter how small their part is and that makes this story more engaging.
The story of Violet Evergarden is one of hardship, tragedy, and a community. Portrayed by a true literary genius, Kana Akatsuki. This story takes its viewers through a roller coaster of emotions and draws them deeper into the story. Through the eyes of a Great War soldier. Violet, a child soldier, goes through a transformation from a once lacking emotional character, to an auto memory doll that writes for others. Where she conveys other emotions onto paper. It is through community, friendship, and healing that Violet follows a path to recovery. One that made her face many trials and allowed her to become a renowned person in her field.

14.THINK: WHAT NEW LIT THEORY LENS DO YOU THINK SHOULD EXIST?
When preparing for this assignment, ask yourself the following
...
yourself the following to start planning your new theory:
Is there a theory we studied that you disagree with? What about it do you dislike or wish to change? Why?
Which theory would you want to expand further or alter to make it more inclusive of a certain group/culture/trend etc.?
What topics in the media angers/upsets/excites/confuses you the most?
While reading The Immortal Life of Henrietta Lacks and/or an essay from The Anthropocene Reviewed, were you particularly drawn to certain events/characters/settings/symbols etc.?
What is your favourite genre of media? (i.e. novels, films, short stories/films, articles, TV shows, poetry, advertising, social media etc.)
CREATE: Now use your brainstorming and knowledge of literary theories to create a new school of literary criticism and apply it to either Henrietta Lacks OR The Anthropocene Reviewed, and one other text of your choice.
PRESENT: Design and create a multimedia presentation that incorporates words and images/graphics presenting your new theory.
What kind of multimedia presentation should I create? E.g. a slideshow of 10-15 slides, a video no longer than 2 minutes, an infographic, an annotated painting/graphic design, magazine article/issue
Your multimedia presentation must include the following:
a unique name for your new theory
a brief definition for your theory - types of questions to ask yourself when using your lens
a brief rationale statement for your theory (rationale is basically why you believe this theory needs to exist and how it was inspired)
an application of your theory to any piece of literature (novel, play, short story, fairy tale) or alternate media text (TV show, comic, advertisement, painting, film clip) **Note: You will have to summarize/introduce your choice of text (e.g. film clip, fairy tale, comic, painting etc.) before you apply your theory
an application of your theory to one passage approx. 250 words long from The Great Gatsby. (not the passage you chose from Lit Theory Assignment #1)
Complete the “Student Comments” part of the rubric (see below) evaluating your final piece
Check out some Level 4 examples to get an idea of what a new theory and its application could look like for student selected texts.

15.This first part of the Individual Research Project is an Outline and Annotated Bibliography. The
Outline should provide a very brief
...
tline should provide a very brief overview of what you think you will do in the Policy Brief.
The Annotated Bibliography requires you to summarize at least three peer-reviewed scholarly
sources you will cite in the Policy Brief.
This assignment is designed to get you thinking about your topic in a way that clearly anticipates
the writing you will do for the Policy Brief. We want you to brainstorm and do a bit of research
well in advance of the deadline for the Policy Brief and, most importantly, we want you to put
your ideas down on paper so that we can give you feedback before writing the actual Policy
Brief. In other words, we are asking you to submit an Outline and Annotated Bibliography so
that we can help you write the best Policy Brief possible.
Your Outline should be divided into the following five sections and should be written in
complete sentences:
I. Audience: Identify the audience you are addressing and consider what that audience
is interested in. Who are you talking to in the Policy Brief and what does this suggest
about the approach you should take? (75-100 words).
II. Problem: State how you know the issue exists. What is the proof that students need
to improve this skill? (125-150 words).
III. Importance of Problem: Indicate why this problem matters. What are the
consequences of the problem not being addressed? Why do students need to improve
this skill? (100 words)
IV. Solution: Identify your preferred solution. What solution will work in your context
and why? (75-100 words)
V. Alternative Solution: Identify at least one other possible solution. What other
solutions did you consider? (75-100 words)
The total length of the Outline should be between 450 and 550 words.
When you submit your Outline, you must also include an Annotated Bibliography. An Annotated
Bibliography is an alphabetical list of research sources that provides bibliographical data (the
title, author, date, publisher, etc.) and a short summary or annotation of the source.
Your Annotated Bibliography should contain a minimum of three scholarly or peer-reviewed
sources, each with an accompanying annotation that is between 150 and 250 words long. The
annotations must summarize the research question or thesis, research methodology, results, and
conclusion. Annotations must include summaries and paraphrased information, NOT quotations.
A good annotation will include two separate paragraphs: 1) a paragraph summarizing the
research question or thesis, research methodology, results and conclusion; and 2) a paragraph
commenting on why this source is relevant for your research.

The following is an excerpt from a letter sent by Henry Wallace to President Truman, July 23, 1946. From the
...
. From the Harry S Truman Papers, Harry S Truman Library, Independence, Missouri. Henry Wallace, a former Vice President of the United States, was a critical observer of US policies during the start of the Cold War. He believed US actions were as much to blame as Soviet actions in the starting of the Cold War.
“How do American actions since V-J Day appear to other nations? I mean by actions the concrete things like $13 billion for the War and Navy Departments, the Bikini tests of the atomic bomb and continued production of bombs, the plan to arm Latin America with our weapons, production of B-29s and planned production of B-36s, and the effort to secure air bases spread over half the globe from which the other half of the globe can be bombed. I cannot but feel that these actions must make it look to the rest of the world as if we were only paying lip service to peace at the conference table.
These facts rather make it appear either (1) that we are preparing ourselves to win the war which we regard as inevitable or (2) that we are trying to build up a predominance of force to intimidate the rest of mankind. How would it look to us if Russia had the atomic bomb and we did not, if Russia had 10,000-mile bombers and air bases within a thousand miles of our coastlines, and we did not?
Our basic distrust of the Russians, … stems from differences in political and economic organization…I am convinced that we can meet that challenge as we have in the past by demonstrating that economic abundance can be achieved without sacrificing personal, political and religious liberties.
Our actions to expand our military security system-such steps as extending the Monroe Doctrine to include the arming of the Western Hemisphere nations, our present monopoly of the atomic bomb, our interest in outlying bases and our general support of the British Empire-appear to them as going far beyond the requirements of defense.”
Henry A. Wallace, Letter Sent to President Truman, July 23, 1946

likely could be a beneficial practice.Why? Arising contemplates show that air contamination is connected to
disabled judgment, emotional well-being issues, more unfortunate execution in school and most worryingly
maybe, more elevated levels of crime.These discoveries are largely the really disturbing, given that more than
a big part of the total populace now live in metropolitan conditions – and a greater amount of us are going in
blocked regions than any time in recent memory. However, perhaps, he thought, there could be other unfavorable
impacts on our lives.To start with, he led an investigation seeing whether air contamination had an
impact in psychological performance.Roth and his group saw understudies taking tests on various
days – and furthermore estimated how much contamination was noticeable all around on those given days. Indeed, even a couple
days prior and a couple of days after, they discovered no impact – it's truly upon the arrival of the test
that the grade diminished altogether. To decide the drawn out impacts, Roth followed up
to perceive what affect this had eight to 10 years after the fact. In this way, he daid that regardless of whether it's a present moment
impact of air contamination, on the off chance that it happens in a basic period of life it truly can have a drawn out impact. In
2018 examination, his group broke down two years of wrongdoing information from more than 600 of London's discretionary
wards, and tracked down that more insignificant violations happened on the most dirtied days, in both rich and
poor areas.Although we ought to be careful about reaching determinations about connections, for example,
these, the creators have seen some proof that there is a causal link.Wherever the haze of
contamination ventures, wrongdoing increments. As a feature of a similar report, they thought about unmistakable regions
over the long haul, just as following degrees of contamination over the long haul. This implies that an intercession at
an early age ought to be a priority.Exposure to different poisons can cause aggravation in the
cerebrum. There are numerous potential components that may clarify how air contamination influences our
morality.Lu, for example, has shown that the simple considered contamination can impact our
brain science through its negative associations.Naturally, the scientists couldn't
truly uncover members with contamination, so they took the following best (morally supported) venture
so they asked them to truly envision living around here, and how they would feel and how their life
would be living in this climate, to make them mentally experience air contamination
versus a perfect climate. He tracked down that the member's tension expanded, and they became
more self-focussed – two reactions that could increment forceful and flippant
practices. Along these lines, by raising people groups' tension, air contamination can detrimentally affect
conduct. at the point when we are restless we are bound to punch somebody in the face, than when
we are quiet. Lead analyst Joanne Newbury, from King's College London, says she can't
however guarantee that her outcomes are causal, yet the discoveries are in accordance with different investigations proposing a
interface between air contamination and psychological wellness. "It adds to confirm connecting air contamination to
actual medical conditions and air contamination connect to dementia.

Write the NET ionic equation for the neutralization reaction.
OH⁻ (aq) + H⁺ (aq) → H2O (l)
Compute the pH of the titration solution. Show your work
i) before any of the base is added
ii) after 25. mL of base is added
iii) after 50. mL of base is added
A student performs the titration with the same chemicals but with smaller volumes of each chemical . Which of the following titration curves could represent the titration. Explain
A because this entails a strong acid and a strong base.
Question 2
A student performs a titration of an unknown acid with a strong base and gets the following titration curve:
a) The student consults the list of pKa of acids shown below. If the acid is listed in the table below, which is the most likely identity of the unknown acid? Explain.
Acid

HF
7.2 x 10-4
CH3COOH
1.8 x 10-5
H2CO3
4.3 x 10-7
HBrO
2.0 x 10-9
The unknown acid is HBrO because the calculated Ka is in between 50^-4 and 50^-6 and 2.0 x 10^-9 lies in between them.
b) What is the initial molarity of the acid?
10^-3 = 0.001M
Question 3
a) Describe the components and the composition of an effective buffer solution. Explain how the components of the buffer allow the buffer to maintain its pH.
An effective buffer solution has a weak acid and its conjugate base or a weak base and its conjugate acid. A buffer solution is most effective when the ratio of its component concentrations is close to 1, also when the pH is equal to the pka of the acid.; The components of the buffer allow the buffer to maintain its pH because buffers can absorb excess H+ions or OH– ions.
An employer is interviewing four applicants for a job as a laboratory technician and asks each how to prepare a buffer solution with a pH of 5.0. The following constants may be helpful: hydrazoic acid, pKa = 4.74 Boric acid, pKa = 9.23
Archita A. says she would mix equal molar solutions of hydrazoic (HN3) and sodium azide (NaN3) solutions.
Bradley B. says she would mix equimolar Boric acid (H3BO3) and HCl solutions.
Carlos C. says he would mix equimolar Boric Acid (H3BO3) and sodium dihydrogen borate (NaH2BO3) solutions.
Delia D. says he would mix equimolar hydrazoic Acid (HN3) and NaOH solutions.
b) Which of these applicants has given an appropriate procedure? Explain your answer
Delia because she is using Sodium hydroxide which results in a pH of 5. NaOH is a strong base and in order to have an effective buffer a weak acid must be incorporated which is the HN3.
c) Explain what is wrong with the erroneous procedures.
The rest all incorporate a strong acid and a strong base or a weak acid and a weak base which don’ result in an effective buffer.
d) The applicants have access to the 1 Liter volumes of each of the solutions listed above. They have access to graduated cylinders. In order to make 1.0 Liter of the correct 5.0 buffer solution, what volumes of the two chemicals must be mixed?

38.I just need someone to look over my paper for anatomy and to just let me know what I need
...
t or add. I'll attach the questions, my rubric, as well as my answers I made. It would really help me out please.
The questions:
1.) Choose two somatosensory receptors. Please include a description of each receptor, what they sense, and which part of the brain processes the information from the receptor.
2.) Provide a discussion of the thyroid gland. Include the following:
Description of the thyroid gland's structure and location.
Description of the cells of the thyroid gland.
Description of the hormones secreted by the thyroid gland and their functions.
Description of how thyroid hormones are controlled by hormones secreted by the hypothalamus and anterior pituitary gland.
Description of how the feedback system works in the cases of high or low thyroid hormone levels.
3. Describe the cardiac cycle. Include descriptions of the 3 phases, the pressure changes in each of the heart's chambers, valves are open and closed, and blood flows during each step.
My answer: 1.) Exteroceptor - receives external stimuli from outside of the body. An example, the skin (Thermoreceptors) detects the temperature of the outside area of the body.
Interceptor - receives stimuli from inside of the body. An example would be blood pressure as well as blood oxygen levels.
2.) Thyroid Gland is located near the front lower part of the neck, beneath Adam's apple. Its structure includes Thyroid Epithelial that form follicles filled with colloid - a protein-rich reservoir of the materials needed for thyroid hormone production. The cells are responsible for releasing hormones that control metabolism (Energy levels). The thyroid gland releases triiodothyronine (T3) and thyroxine (T4). These hormones regulate weight, energy levels, internal temperature, skin, and growth. When the hypothalamus and pituitary function well, they can detect when hormone levels are low, which causes them to produce more TRH and TSH, which stimulates the thyroid to produce hormones. When the hormone levels exceed their limit, they then have less TRH and TSH, which results in reduced hormone production by the thyroid. Feedback is when a product feeds back into its initial cycle. The Feedback includes both positive and negative feedback. Positive Feedback is when a product provides back to increase production: an example, milk production by a mother for her baby. As the baby suckles, nerve messages from the nipple cause the pituitary gland to secrete prolactin. Prolactin, in turn, stimulates the mammary glands to produce milk, so the baby suckles more. Which causes more prolactin to be secreted and more milk to is made. Negative Feedback is when a product feeds back decreases production; it brings down show if they increase past their limit. It also controls insulin secretion by the pancreas.
3.) The Cardiac Cycle takes place from the beginning of a heartbeat to the next. It contains two periods: One is when the heart muscle relaxes and refills with blood, called diastole, following a time when it begins contraction and pumping of blood, systole. Once emptied, the heart then relaxes and expands to receive another inrush of blood coming back from the lungs and other areas of the body. The atrioventricular valves remain open while the semilunar valves are closed. During the middle part of the diastole, a small amount of blood flows into the ventricles. The blood flows from the veins and passes the atria fills the ventricles. The pressure in both ventricles is close to zero as a result.

Question 1:
A block of mass M = 0.10 kg is attached to one end of a spring with spring constant k = 100 N/m . The other end of the spring is attached to a fixed wall. The block is pushed against the spring, compressing it a distance x = 0.04 m . The block is then released from rest, and the block-spring system travels along a horizontal, rough track. Data collected from a motion detector are used to create a graph of the kinetic energy K and spring potential energy Us of the system as a function of the block's position as the spring expands. How can the student determine the amount of mechanical energy dissipated by friction as the spring expanded to its natural spring length?
Question 2:
The Atwood’s machine shown consists of two blocks connected by a light string that passes over a pulley of negligible mass and negligible friction. The blocks are released from rest, and m2 is greater than m1. Assume that the reference line of zero gravitational potential energy is the floor. Which of the following best represents the total gravitational potential energy U and total kinetic energy K of the block-block-Earth system as a function of the height h of block m1?
Question 3:
A 2 kg block is placed at the top of an incline and released from rest near Earth’s surface and unknown distance H above the ground. The angle θ between the ground and the incline is also unknown. Frictional forces between the block and the incline are considered to be negligible. The block eventually slides to the bottom of the incline after 0.75 s. The block’s velocity v as a function of time t is shown in the graph starting from the instant it is released. How could a student use the graph to determine the total energy of the block-Earth system?
Question 4:
A block slides across a flat, horizontal surface to the right. For each choice, the arrows represent velocity vectors of the block at successive intervals of time. Which of the following diagrams represents the situation in which the block loses kinetic energy?

58.students are expected to research and compose a paper based on the application of concepts and theories examined in class.
...
ies examined in class. This paper is not a literature review, though a literature review is part of your work. As this course takes place in a compressed timeline, I provided some suggestions for research topics. Feel free to use one of these as a springboard or propose your own.
At the end of the second week of class, students submit a three-page research paper prospectus. A research prospectus is a preliminary plan for conducting a study. This is not a detailed and technical research proposal, but rather, an analysis of the issues likely confronted in such a study. In essence, it is a preliminary proposal of work.
Research Paper Prospectus Elements
To complete the Research Paper Prospectus, consider the following elements. While the prospectus is limited to three pages of body content, remember, students must cover each of these areas as relevant to the plan for research:
Research Problem. What is the research problem? A problem is a situation when left untreated, produces a negative consequence for a group, an institution, or a(n) individual(s). What makes it a problem? For whom? Who says so?
Assumptions. On what assumptions is the work based? Which assumptions are verifiable in literature? Which assumptions are speculative?
Theoretical Issues. What theoretical issues arise from the study? For example, "theoretically," how is the problem and suspected results explained to other scholars? Is there a behavior view? A social systems view? Are there other theoretical orientations to consider in the study's design?
Literature Review. What, in general, does the literature say about the topic? While more development is expected for the final paper, a review of major theories, research, and writers in the field is needed.
Research Questions. Based on the problem, what are the research questions to be answered? How and why will answering the questions contribute to solving the research problem? Remember....a research question can only be answered with empirical data or information.
General Research Plan. In general, what research is necessary to answer the research question. What kind of data is needed? Specify the type, such as surveys, observations, or interviews. Who is to be studied and why? How is the data reduced and made sense of? How is the quality of the data assured?
Anticipated Difficulties and Pitfalls. What kind of difficulties and pitfalls are expected in a study of this nature? What can be done to prevent them or minimize their effects?
Anticipated Benefits. Who will benefit from the fact this research is undertaken? How? Why? Who might be disturbed by this proposed study? How? Why?
Paper Format Requirements
The Research Paper Prospectus is presented in standard APA 7 format, with a cover page, running head, body, and references list. The cover page and references do not count toward the three-page requirement. The body uses headers and in-text citations in the manner prescribed by APA. Students should include any references they know at the time they submit the prospectus, though it is expected the references may change or increase in number. Full and complete adherence to APA is required.
APA Basics
As APA format is the rule, remember the formatting rules shown on the Sample Paper (Links to an external site.):
Times New Roman, 12pt
1" margins on all sides
Double spaced, with extra line spaces removed (see below)
Page numbers in the upper right
Two spaces after concluding punctuation
150-250 word abstract with keywords
APA-style in-text citations and quote format. Use the Purdue OWL in-text citation information (Links to an external site.)to help you.
Alphabetical (by author) reference page with correct reference format. DO NOT trust the reference generator in your word processing program. It is WRONG! Use the Purdue OWL references information (Links to an external site.)to correctly structure references and do so manually.

erest to this study.
Needless to say, this sales strategy will be effective when the distribution channels for the product in question are well planned, when there is sufficient advertising to let the consumers know about the promotion, when the package clearly indicates the coupon redemption scheme with the expiration date, if any, and the packaging of the product is of the right size (neither too big nor too small to serve the needs of the consumer). Of course, all these factors will not help, unless there is an established frequent need for the product for consumers.
Develop a theoretical framework for the above mentioned scenario.
(5 marks)
Ques. 14
Read the following information identify the concepts and develop a conceptual model for the scenario below.
Incidence of smoking in movies has started to increase again, after having declined for several decades. According to the National Cancer Institute smoking is seen in at least three out of four contemporary box office hits. What's more, identifiable cigarette brands appeared in about one-third of all movies in 2019. Exposure to smoking in movies is an important predictor of adolescent smoking initiation: smoking in movies has been shown to affect adolescents' intentions to start smoking. In turn, the intentions to start smoking are determined by a more positive attitude toward smoking after seeing a film character smoke. Recent research has revealed that the relationship between seeing a film character smoke and the attitude toward smoking is stronger when a person's identification with a film character increases. These findings are consistent with social learning theory, which predicts that attitudes and behaviors are modeled by observing the behaviors of others.

83.Task 1
You are asked to carry out a study on behalf of a business analytics specialised consultancy on a subsample
...
on a subsample of weekly data from Randall’s Supermarket, one of the biggest in the UK. Randall’s marketing management team wishes to identify trends and patterns in a sample of weekly data collected for a number of their loyalty cardholders during a 26-week period. The data includes information on the customers’ gender, age, shopping frequency per week and shopping basket price. Randall’s operates two different types of stores (convenient stores and superstores) but they also sell to customers via an online shopping platform. The collected data are from all three different types of stores. Finally, the data provides information on the consistency of the customer’s shopping basket regarding the type of products purchased. These can vary from value products, to brand as well as the supermarket’s own high-quality product series Randall’s Top. As a business analyst you are required to analyse those data, make any necessary modifications in order to determine whether for any single customer it is possible to predict the value of their shopping basket.
Randall’s marketing management team is only interested in identifying whether the spending of the potential customer will fall in one of three possible groups including:
• Low spender (shopping basket value of £25 or less)
• Medium Spender (shopping basket value between £25.01 and £70) and
• High spenders (shopping basket greater than £70)
For the purpose of your analysis you are provided with the data set Randall’s.xls. You have to decide, which method is appropriate to apply for the problem under consideration and undertake the necessary analysis. Once you have completed this analysis, write a report for the Randall’s marketing management team summarising your findings but also describing all necessary steps undertaken in the analysis. The manager is a competent business analyst himself/herself so the report can include technical terms, although you should not exceed five pages. Screenshots and supporting materials can be included in the appendix.
Requirements
After completing your analysis, you should submit a report that consists of two parts. Part A being a non-technical summary of your findings and Part B a detailed report of the analysis undertaken with more details.
Part A: A short report for the Head of Randall’s Marketing Management (20 per cent). This should briefly explain the aim of the project, a clear summary and justification of the methods considered as well as an overview of the results.
Although, the Head of Randall’s Marketing Management team who will receive this summary is a competent business analytics practitioner, the majority of the other team members have little knowledge of statistical modelling and want to know nothing about the technical and statistical underpinning of the techniques used in this analysis. This report should be no more than two sides of A4 including graphs, tables, etc. In this report you should include all the objectives of this analysis, summary of data and results as well as your recommendations (if any).
Part B: A technical report on the various stages of the analysis (80 per cent).
The analysis should be carried out using the range of analytics tools discussed:
• SPSS Statistics
Ensure that the exercise references:
• Binary and multinomial logistic regression
• Linear vs Logistic regression
• Logit Model with odds Ratio
• Co-efficients and Chi Squared
• MLR co-efficients
• Assessing usefulness of MLR model
• Interpreting a model
• Assessing over-all model fit with Psuedo R-Squared measures
• Classification accuracy (Hit Ratio)
• Wald Statistic
• Odd ratio exp(B)
• Ratio of the probability of an event happening vs not happening
• Ratio of the odds after a unit change in the predictor to the original odds
• Assumptions
• Residuals analysis
• Cook’s distance
• DfBeta
• Adequacy (with variance inflation factor VIF and tolerance statistic)
• Outliers and influential points cannot just be removed. We need to check them (typo? – unusual data?)
• Check for multicollinearity
• Parsimony
Write a short and concise report to explain the technical detail of what you have done for each step of the analysis.
The report should also cover the following information:
• Any type of analysis that might be useful and check whether the main assumptions behind the analyses do not hold or cannot be
• Give evidence of the understanding of the statistical tools that you are using. For example, comment on the model selection procedure and the coefficient interpretation, e.g. comment on the interpretation of the logistic regression coefficients if such a method is used and provide an example of
• Conclusions and explanation, in non-technical terms, of the main points

inefficiencies, etc), and suggest an improved process. Open and read the Process Improvement (Final Q 1)
document which describes the process steps in words and also includes a process map as a visual tool for understanding what's going on in each step. You will need to respond to the following three sub-questions:
FINAL Q1: 3 Attachments are the Q1
------------------------------------------------------------------------------------------------------------------------------------------------------------------
I need the 3 part question answered. This is everything in the question.. Understand that there is NOTHING INCOMPLETE, I have added everything that was sent to us.
------------------------------------------------------------------------------------------------------------------------------------------------------------------
a. Of the 9 process steps in the Process Improvement (Final Q 1) document, which specific steps in that process are experiencing lean wastes and/or process cycle time issues (please note, there is more than one step experiencing issues). In your response, name the process step, and/or the transfer interface between steps, and what waste(s) or cycle time issue is involved. Be sure to use standard lean/six sigma terminology that we used in the course when referring to any of the quality concepts; e.g., transportation waste when referring to situations involving a lot of moving around from one place to another.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
b. Which of the process steps you identified in part a do you believe could benefit from process improvement and why?
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
c. What changes would you institute in the process to improve the steps you cited in part b of this question and describe how those changes improves the process. Be specific about which process step(s) your improving and thoroughly describe the improvement to that step. [Note: This question ties to what you decided was important in part b question above.] Also, when answering how you would improve a given process step, assume you have an unlimited budget and personnel resources and you can do mostly anything you want as long as it doesn't violate the laws of physics or the judicial system. Be cautious though because process improvement is designed to save time, money, and resources in doing the needed work.For example, automation is good, and also potentially expensive, so is it worth it for the improvement? - you will have to be the judge of that.

One demonstration of interference examines the process of forgetting while subjects are asleep versus while they are awake. Because there should be less interference during sleep, there also should be less forgetting. The following data are from an experiment examining six groups of participants. All participants were given a group of words to remember. Then half of the participants went to sleep, and the others stayed awake (factor A). Within both the asleep and awake groups, one third of the participants were tested after 2 hours, one third after 4 hours, and one third after 8 hours (factor B). The experimenter recorded the number of words correctly recalled.

eo of Trump's hair,Relaxed and with hair blowing in the breeze, more looks like in the Pantene ad than in the viral video of Trump's hair, I pedaled over bumpy, dusty dirt paths around my 'dacha', the rural cottage, where like the most of Soviet children were spending the entire summer.
The bike wasn't mine. I have never had one. My family couldn't afford it. I borrowed it from my older neighbor. She was at that age when girls are starting to think more about a look and an outfit, rather than enjoying the thrill of a bicycle ride. But her bike wasn't available all the time, so I had to be persuasive to get a vehicle from someone else or to be an outsider-pedestrian. Recently, I was thinking, what if we would have this ‘sharing-mobility back then (to my childhood time).
But I was growing up before technology was everywhere and the internet was a thing. In those days, hand brakes and gears were unseen. Riders never wore helmets or special clothing and there were no bicycle lanes marked on streets. We couldn't buy a kick-scooter in a store, so we handmade it from wooden crates from landfills. Bicycles were prized possessions in the neighborhood. Much has changed in the 30 years since on both sides of the ocean.
Back in the 2010s, I worked as a project manager of the Russian Innovation Convention in Moscow, со-organized by Skolkovo’s Technopark and took place at the Skolkovo Innovation Center, Russia's version of Silicon Valley.
Working at the conventions of 2010 - 2012, I managed guests lists of 10+ thousand participants, young innovators, and entrepreneurs, looking for self-fulfillment in science and high-tech economy. I also worked closely with government officials and high profile speakers from the sphere of innovation. From 2010 to 2012 there were many renowned guests at the Convention, such as Richard Branson(Virgin); Bill Tai (KiteVC), Steve Wozniak (Apple), Harzh Taggar (“Y Combinator”) and so on. For me it was a unique opportunity to see both sides of the coin - get experience, and useful contacts to launch my venture somewhere in the future.
The Skolkovo "innovation town" outside Moscow, backed by technology-adherent Russian President Dmitry Medvedev as part of his modernization drive, was supposed to become the country's most ecologically friendly town, with cycle tracks, solar panels, and windmills. These ideas have appeared as a result of encouraging / inspirational visit of Mr. Medvedev and other Russian officials to the original Silicon Valley in California in 2010.
I remember when I first visitied Googleplex - Google's campus, it was unbelievable that the bikes come in all shapes and sizes, and are available to pretty much anyone to take just about wherever they please. It was truly brilliant! Google has a large campus that is spread across many miles and buildings. To get from one place to another would be a hassle without the bikes.
Over the past decade, corporate bike fleets have become commonplace on Silicon Valley campuses - Apple, Facebook, and others have campus bikes. Dockless and docked bikes have already occupied big cities. Almost 10 years later, Russia's version of Silicon Valley still doesn’t have anything similar. E-bikes are good, but E-scooters might be the new thing.
Having ties with my former colleagues at Skolkovo, we are negotiating that the technopark will launch BRiZ e-scooters sharing in 2020. The system should help Skolkovo employees move faster across a fairly large area of the center. BRIZ is a smart dock-less mobility platform, which offers dock-free electric scooter rentals to fulfill short distance, urban and other trips. I am the co-founder and CEO of BRiZ Mobility.

But, let's start from the very beginning.
I am a politician, public servant and started my career as a grassroots organizer in 2006. In the decade since, I have taken part in several political movements, coordinated numerous political events, organized a political party, run for office, and held leadership positions in the federal government.
Since I became involved in public service, I’ve been always advocating for government transparency. The information era and its accompanying tech boom expanded my toolkit. From 2013 to 2016, I coordinated grant competitions for youth all over Russia at the Ministry of Education and its subdivision Federal Agency of Youth Affairs. Two of the biggest challenges facing my team were securely collecting and storing personal data of the participants (33 million youth people in Russia) and implementing a transparent, fair process for selecting grant winners and distributing funds to them. Our solution, the Automatic Information System (AIS) "Youth of Russia," was implemented in 2014, and since then this system is operating. This experience was valuable in terms of managing developers' team, develop a user-friendly big data platform, as well as pushing the slow bureaucratic structures on digital reforms.
I completed my Master's degree in 2015 and started my PhD, doing my Masters's degree in Public Administration and a Ph.D. in economics simultaneously. I was then recruited by Moscow Government to work on the preparation of Moscow as one of the Host Cities for the 2018 FIFA World Cup. However, sometime later, my application was accepted by three Ivy League universities and I moved to New York to study at Columbia University, School of international and public affairs in 2017.
The past year at Columbia University has shifted my academic and professional passions towards the Sustainable Development Goals, among them Sustainable cities and communities (including transportation), 'Gender Equality, and its influence on a broad range of fields.
At SIPA, I chose Management & Innovation Concentration. Because my background wasn't in tech, I knew I needed to fill some skill gap areas. So I took the opportunity to load up on courses that focus on innovations, sustainability, and urban policy. One of the extremely useful classes was 'Strategic Management of Information & Communications Technologies for the Public Good with Prof. Robert Z Tumin, where we have been examining different policy and managerial cases, and use of established and leading-edge information and communication technologies, among them in transportation (Uber Case). Another one was 'Implementation of Sustainability Strategies' with Prof. Todd Cort. One of the final research project at that class was related to the environmental impact of transport in Europe and the analysis of the combination of bikes and trains that can provide an alternative to less sustainable modes, such as private motor vehicles. In the Fall of 2018, my final portfolio project at SIPA had transformed into my startup business plan, investor pitch deck, and profound research on the market opportunity and competition.
My team and I launched the company in February 2019. In the past 9 months following up on the launch of BRiZ, I have been working on a series of tasks to get the business off the ground. So that included everything from submitting our incorporation documents, raising capital, negotiating with suppliers, implementing operations, and developing partnerships to get the business fully up and running. Now that we have launched, my job is continuing to fundraise, work towards our expansion goals, work with governments and oversee the day-to-day operations.
Having a public policy background, I also the one who will manage the implementation of technology that will help the company to work smoothly with regulators. BRiZ’s engineers work on imposing parking restrictions so that scooters can’t be parked in spaces rejected by a city; imposing speed limits on scooters within certain parts of a city, and lock scooters that violate those rules. Besides controlling how its scooters work, BRiZ can share its data with city officials to help cities understand traffic patterns and find the best settings for these green transportation solutions. If we have a good relationship with the city, we’ll be able to find the sensible ground where we’re truly improving transportation.
According to my research, made before launching BRiZ, most of the electric kick scooters in the scooter-sharing market were designed with serious downsides, such as short lifespan, loads of unnecessary functions, lacking must-have safety features, etc. So, we recreated something that everyone already knows and creates a functional and smart prototype - more efficient - two times longer lifespan (12 months) and is, therefore, two times more profitable than potential competitors. We are going to start with launching a pilot sharing platforms at the beginning of 2020, in major cities around New York; and in Spring 2020 in several major Russian cities and Skolkovo ‘innovation town’. Now, we are meeting different strategic partners and take negotiations with municipalities.
eScooters have flooded the streets of world cities. Cities are relatively down for this new era of transportation. Fans of micro-mobility praise its ability to provide efficient and eco-friendly rides. Opponents have questioned the safety and sustainability of micro-mobility. In media micro sharing mobility as part of the trend of the sharing economy can be described as the future durable trend so as a new version of communism.
As a millennial leader thinking about trends transforming the global landscape, I would like to utilize my skills, experience, and expertise in issues relating to the interface between sustainable urban development and transport technologies. I am confident that I would bring a strong foundation in understanding the current and future trends. In my objectives to create the multi-functional platform / system to make our urban logistics safer, cleaner, healthier, fairer, and more productive, and to examine the deeper implications of where this new transportation technology wave has led us—and where we want to go next. I see the common ground and research direction with 'The City Science' and Viral Communications research groups. questions cannot be answered in separation. Working under the mentorship at the Lab I want to continue my interdisciplinary trajectory in academic research and practical work.
So, today, I’m back on two wheels, helmet strapped on, following new millennial rules of the road. Relaxed and with hair blowing in the breeze, ride/scoot an electric BRiZ into 2020 to figure out what's going on.

107.Relaxed and with hair blowing in the breeze, more looks like in the Pantene ad than in the viral video
...
eo of Trump's hair, I pedaled over bumpy, dusty dirt paths around my 'dacha', the rural cottage, where like the most of Soviet children were spending the entire summer.
The bike wasn't mine. I have never had one. My family couldn't afford it. I borrowed it from my older neighbor. She was at that age when girls are starting to think more about a look and an outfit, rather than enjoying the thrill of a bicycle ride. But her bike wasn't available all the time, so I had to be persuasive to get a vehicle from someone else or to be an outsider-pedestrian. Recently, I was thinking, what if we would have this ‘sharing-mobility back then (to my childhood time).
But I was growing up before technology was everywhere and the internet was a thing. In those days, hand brakes and gears were unseen. Riders never wore helmets or special clothing and there were no bicycle lanes marked on streets. We couldn't buy a kick-scooter in a store, so we handmade it from wooden crates from landfills. Bicycles were prized possessions in the neighborhood. Much has changed in the 30 years since on both sides of the ocean.
Back in the 2010s, I worked as a project manager of the Russian Innovation Convention in Moscow, со-organized by Skolkovo’s Technopark and took place at the Skolkovo Innovation Center, Russia's version of Silicon Valley.
Working at the conventions of 2010 - 2012, I managed guests lists of 10+ thousand participants, young innovators, and entrepreneurs, looking for self-fulfillment in science and high-tech economy. I also worked closely with government officials and high profile speakers from the sphere of innovation. From 2010 to 2012 there were many renowned guests at the Convention, such as Richard Branson(Virgin); Bill Tai (KiteVC), Steve Wozniak (Apple), Harzh Taggar (“Y Combinator”) and so on. For me it was a unique opportunity to see both sides of the coin - get experience, and useful contacts to launch my venture somewhere in the future.
The Skolkovo "innovation town" outside Moscow, backed by technology-adherent Russian President Dmitry Medvedev as part of his modernization drive, was supposed to become the country's most ecologically friendly town, with cycle tracks, solar panels, and windmills. These ideas have appeared as a result of encouraging / inspirational visit of Mr. Medvedev and other Russian officials to the original Silicon Valley in California in 2010.
I remember when I first visitied Googleplex - Google's campus, it was unbelievable that the bikes come in all shapes and sizes, and are available to pretty much anyone to take just about wherever they please. It was truly brilliant! Google has a large campus that is spread across many miles and buildings. To get from one place to another would be a hassle without the bikes.
Over the past decade, corporate bike fleets have become commonplace on Silicon Valley campuses - Apple, Facebook, and others have campus bikes. Dockless and docked bikes have already occupied big cities. Almost 10 years later, Russia's version of Silicon Valley still doesn’t have anything similar. E-bikes are good, but E-scooters might be the new thing.
Having ties with my former colleagues at Skolkovo, we are negotiating that the technopark will launch BRiZ e-scooters sharing in 2020. The system should help Skolkovo employees move faster across a fairly large area of the center. BRIZ is a smart dock-less mobility platform, which offers dock-free electric scooter rentals to fulfill short distance, urban and other trips. I am the co-founder and CEO of BRiZ Mobility.
But, let's start from the very beginning.
I am a politician, public servant and started my career as a grassroots organizer in 2006. In the decade since, I have taken part in several political movements, coordinated numerous political events, organized a political party, run for office, and held leadership positions in the federal government.
Since I became involved in public service, I’ve been always advocating for government transparency. The information era and its accompanying tech boom expanded my toolkit. From 2013 to 2016, I coordinated grant competitions for youth all over Russia at the Ministry of Education and its subdivision Federal Agency of Youth Affairs. Two of the biggest challenges facing my team were securely collecting and storing personal data of the participants (33 million youth people in Russia) and implementing a transparent, fair process for selecting grant winners and distributing funds to them. Our solution, the Automatic Information System (AIS) "Youth of Russia," was implemented in 2014, and since then this system is operating. This experience was valuable in terms of managing developers' team, develop a user-friendly big data platform, as well as pushing the slow bureaucratic structures on digital reforms.
I completed my Master's degree in 2015 and started my PhD, doing my Masters's degree in Public Administration and a Ph.D. in economics simultaneously. I was then recruited by Moscow Government to work on the preparation of Moscow as one of the Host Cities for the 2018 FIFA World Cup. However, sometime later, my application was accepted by three Ivy League universities and I moved to New York to study at Columbia University, School of international and public affairs in 2017.
The past year at Columbia University has shifted my academic and professional passions towards the Sustainable Development Goals, among them Sustainable cities and communities (including transportation), 'Gender Equality, and its influence on a broad range of fields.
At SIPA, I chose Management & Innovation Concentration. Because my background wasn't in tech, I knew I needed to fill some skill gap areas. So I took the opportunity to load up on courses that focus on innovations, sustainability, and urban policy. One of the extremely useful classes was 'Strategic Management of Information & Communications Technologies for the Public Good with Prof. Robert Z Tumin, where we have been examining different policy and managerial cases, and use of established and leading-edge information and communication technologies, among them in transportation (Uber Case). Another one was 'Implementation of Sustainability Strategies' with Prof. Todd Cort. One of the final research project at that class was related to the environmental impact of transport in Europe and the analysis of the combination of bikes and trains that can provide an alternative to less sustainable modes, such as private motor vehicles. In the Fall of 2018, my final portfolio project at SIPA had transformed into my startup business plan, investor pitch deck, and profound research on the market opportunity and competition.
My team and I launched the company in February 2019. In the past 9 months following up on the launch of BRiZ, I have been working on a series of tasks to get the business off the ground. So that included everything from submitting our incorporation documents, raising capital, negotiating with suppliers, implementing operations, and developing partnerships to get the business fully up and running. Now that we have launched, my job is continuing to fundraise, work towards our expansion goals, work with governments and oversee the day-to-day operations.
Having a public policy background, I also the one who will manage the implementation of technology that will help the company to work smoothly with regulators. BRiZ’s engineers work on imposing parking restrictions so that scooters can’t be parked in spaces rejected by a city; imposing speed limits on scooters within certain parts of a city, and lock scooters that violate those rules. Besides controlling how its scooters work, BRiZ can share its data with city officials to help cities understand traffic patterns and find the best settings for these green transportation solutions. If we have a good relationship with the city, we’ll be able to find the sensible ground where we’re truly improving transportation.
According to my research, made before launching BRiZ, most of the electric kick scooters in the scooter-sharing market were designed with serious downsides, such as short lifespan, loads of unnecessary functions, lacking must-have safety features, etc. So, we recreated something that everyone already knows and creates a functional and smart prototype - more efficient - two times longer lifespan (12 months) and is, therefore, two times more profitable than potential competitors. We are going to start with launching a pilot sharing platforms at the beginning of 2020, in major cities around New York; and in Spring 2020 in several major Russian cities and Skolkovo ‘innovation town’. Now, we are meeting different strategic partners and take negotiations with municipalities.
eScooters have flooded the streets of world cities. Cities are relatively down for this new era of transportation. Fans of micro-mobility praise its ability to provide efficient and eco-friendly rides. Opponents have questioned the safety and sustainability of micro-mobility. In media micro sharing mobility as part of the trend of the sharing economy can be described as the future durable trend so as a new version of communism.
As a millennial leader thinking about trends transforming the global landscape, I would like to utilize my skills, experience, and expertise in issues relating to the interface between sustainable urban development and transport technologies. I am confident that I would bring a strong foundation in understanding the current and future trends. In my objectives to create the multi-functional platform / system to make our urban logistics safer, cleaner, healthier, fairer, and more productive, and to examine the deeper implications of where this new transportation technology wave has led us—and where we want to go next. I see the common ground and research direction with 'The City Science' and Viral Communications research groups. questions cannot be answered in separation. Working under the mentorship at the Lab I want to continue my interdisciplinary trajectory in academic research and practical work.
So, today, I’m back on two wheels, helmet strapped on, following new millennial rules of the road. Relaxed and with hair blowing in the breeze, ride/scoot an electric BRiZ into 2020 to figure out what's going on.

Homework Assignment:
Write the pseudocode needed to complete Chapter 5, number 9 – Pennies for Pay.
Implement Pennies for Pay in Java.
The Secondhand Rose Resale Shop is having a seven-day sale during which the price of any unsold item drops 10 percent each day. Design a class diagram showing the class, the application program, the relationship between the two, and multiplicity. Then write the Java code as described below. Be sure to follow the CSI 117 Style Criteria (Links to an external site.) for naming conventions, class diagrams, pseudocode, keywords, and operators.
An Inventory class that contains:
an item number and the original price of the item. Include the following:
A default constructor that initializes each attribute to some reasonable default value for a non-existent inventory item.
Another constructor method that has a parameter for each data member, called the overloaded constructor. This constructor initializes each attribute to the value provided when an object of this type is instantiated. Be sure to incorporate adequate error checking for all numeric attributes.
Accessor and mutator methods for each attribute. Be sure to incorporate adequate error checking for all numeric attributes.
Extra credit for including Javadoc comments.
An application program that contains two methods: the main() module and the printSaleData()module.
The main()module must do the following:
create an Inventory object using the default constructor
use a loop to get inventory items from the user. The user should enter the item number and the original price of the item. This loop should continue until the user indicates that they have no more items to enter. For each item entered by the user, the code inside the loop should do the following 2 items:
set the attributes of the Inventory object by calling the appropriate method in the Inventory class for each item entered by the user
send the Inventory items, one at a time, to the printSaleData() module for processing
Extra credit for including Javadoc comments.
The printSaleData()module must accept an Inventory object and produce a report that shows the item number and the price of an inventory item on each day of the sale, one through seven, using a loop. For example, an item with an original price of $10.00 costs 10 percent less, or $9.00, on the first day of the sale. On the second day of the sale, the same item is 10 percent less than $9.00, or $8.10.

...
e investigations we determined that the program input size can be varied in a wide range and for N-bit input the program result is also always N – Bit long. Additionally we found that the program working time depends significantly on input length N, especially when N is greather than 10- 15 . Our test also revealed, that the program working time depends only on input length ,not the input itself.
During our tests, we fixed the following working times (with an accuracy of one hundredth of a second)
N = 2 – 16.38 seconds
N = 5 – 16.38 seconds
N = 10 – 16.44 seconds
N = 15 – 18.39 seconds
N = 20 – 1 minute 4.22 seconds
We also planned to test the program for N = 25 and N = 30, but for both cases the program didn’t finish within half and hour was forced to terminate it. Finally, we decided for N = 30 to not terminate the program,but to wait a little bit longer.The result was 18 hours 16 minutes 14.62 seconds . We repeated the test for N = 30 and it gave us exactly the same result, more than 18 hours.
Tasks:
a) Find the program working times for the following three cases N = 25, N = 40 and N = 50.

DATA Set 1:
Good morning sunshine. Is Time of Day important?
1. Prof. Maya recently read an article that concluded students retained more information when attending classes in the morning. Based on this finding she thought students in her morning class might have performed differently on their Short Answer test scores when compared to students in her evening class. Does the data support her hypothesis? [15 points]
Multiple Guess! Does Exam Type matter?
2. Prof. Maya also knew that students often did better on multiple-choice tests because they only have to recognize the information (rather than recall it). Given this, she thought students attending the morning class might perform differently on the Multiple-Choice test when compared to the Short Answer test. Does the data support her hypothesis? [15 points]

She then chose a random sample of 20 students to receive the new study plan and another sample of 30 to continue using the old study plan. Following an in-class quiz, she divided the students into 3 levels of achievement (below average, average, and above average), and then created the frequency table below.

The poems are provided for you in the overview pages for each period of poetry.
To accomplish that, you must follow the above steps and complete the TPFASTT worksheet in order to gain the information you need to identify the theme/tone and to write about it. You will choose TWO poems on which to write. You will choose TWO. That means you'll have two responses about tone and two responses about theme.
This is important: please make sure that the two poems you choose share the same theme. This is extremely important for being able to write the essay in the final module. They must share the same theme. Consider the following subjects when determining a theme: power, love, control, religion, science, gender roles, death/loss/mourning, beauty, or values.

147.I am having problem with an assignment using lubrication method.
4. To obtain an analytical model of the flow
...
el of the flow in the coating zone x ∈ [0; L], y ∈ [0; h(x)] a lubrication approximation will be developed. If λ >> 1, and if α is close to, but less than 1 the coating zone appears plane. Use the equation of continuity to show by an order of magnitude estimate that |vy| << |vx|. Then state assumptions on flow and pressure field that reduce the Navier- Stokes equation locally to a form, from which the following approximate expression for the x-velocity in the slot for x ∈ [0; L] can be derived:

150.Gun Sales fall by $100 million due to the 'Trump slump' CNBC 9/12/17
"American Outdoor Brands, one of the largest gun
...
e of the largest gun manufacturers in the United States, experienced a 48.5 percent decrease in firearms revenue this quarter compared with the same time last year, The Guardian reports. Sales fell $100 million as a result of what has been called the "Trump slump."
The political climate has influence over gun sales. The expectation of many Americans that Hillary Clinton, the vocal pro-gun-control candidate, was going to win the presidential election in November is considered largely responsible for last year's surge.
People buy firearms at the highest rates when they fear regulations will be enhanced. The mass shooting at an Orlando nightclub shooting in June of 2016 also spurred record sales. According to the FBI's National Instant Criminal Background Check System (NICS), over 27.5 million firearm background checks for gun transactions were processed in 2016. That was over 4 million more than the previous year, and double the number of transactions in 2008."
Based on this article which of the following is true about the supply and demand of guns from 2016 to 2017
A)There was a decrease in demand for guns, and a decrease in the quantity supplied of guns
B)There was a decrease in quantity demanded, and a decrease in quantity supplied of guns
C)There was a decrease in the supply and guns and a decrease in the quantity demanded for guns.
D)There was a decrease in supply and a decrease in demand for guns.

151.I have the following budget constraints for an agent. In the first period of his life, he only can get
...
et loans (he doesn't "earn" income). With the loans (L) he needs to decide between first period consumption (C1) and investment (I). The amount invested will allow him to get a second period income Y with probability P which is increasing in I (therefore, P(I)), In case of success and the person obtain Y, the individual should use Y to repay the loan (L) that he requested in the first period and consume in the second period (C2). However, with probability 1 - P(I), the person don't get Y and therefore only consume C1. Note that if the individual only invest the loan (L=I) and don't obtain Y, he can't consume anything. That motivates him not to invest the whole loan and keep part of the loan in order to warrant at least first period consumption. Therefore, considering B the parameter for the time preference, the problem would be:
max U=ln(C1) + Bln(C2)
s.t: L = I + C1
Y(I) = L(1+r) + C2
with Probability P(I)
or
s.t: L = I + C1
with probability 1 - P(I)
My question is, Have you ever seen something like this? If yes, how to proceed? What is more important, I really need a bibliography (a book or article talking about this)
