2.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:
Submit your code as a Jupiter notebook with the .gcode in it and, and an image of your print.
3.ssay 1: Person I Admire
This essay assignment is the culmination of all your previous work in this module. You have
in this module. You have already engaged in the beginnings of the writing process of this essay. You have:
Brainstormed ideas (see Chapter 11 in SMG) about the essay in the Discussion Board.
Condensed your ideas down into manageable points around a working thesis.
Displayed knowledge of Description essays from Learning Activities
Drafted a Writing Activity (WA2) about this Description essay.
Consulted with a writing tutor to find areas of strength and areas of improvement.
Finally, you will now compose the final draft of a description essay that:
contains a clear thesis
identifies clear points to support your thesis
engages in critical thought about the subject chosen
uses 2-4 main ideas (points) that support your overall essay thesis
allows you to expand on your chosen topic
This essay assignment represents the first steps in writing any written essay for any academic course. The idea of thesis and support are the cornerstones of all essays. They represent the last part of the writing process. However, you may still revise your essay before final submission. This form of essay writing is the basis for all other academic writing pursuits. This skill translates to almost all careers that require critical thinking, critical reading, and responding in writing. Practicing "how to" write an essay carries over into any field's task of "what" you need to write. This skill will help with all formal writing.
Write a 900-word essay, in MLA format, about a person or fictional character in whom you have an interest.
Select a subject (person or fictional character you admire)
Look to your Discussion (D1) and Writing Activity 2 (WA2) for your subject
The person may be current or historical
Some fictional characters have positive traits that can be identified.
Select several (2-4) traits about the person or character that you admire and write about these. These will be the essay's main ideas.
Biographical information should be used only to support claims.
Your essay should focus on the traits you admire. Do not write a biography or tell a story.
Example of what not to do: This person was born in 1979. They were born in middle Tennessee. They went to elementary school is 1985. They graduated in 1998.
Instead, follow this example: This person was born in middle Tennessee. Entering elementary in school in 1985 was hard for them. They never felt that they belonged in kindergarten. However, they persevered, learning that school was a place for them to grow and be themselves.
Focus on the "why" you admire them instead of a list of traits. In the above example, perseverance and learning to be themselves are the traits the writer of the essay admires.
Organize your main ideas to establish the essay's pattern of organization.
Your main ideas (traits you have chosen) need to be clearly organized.
Decide in what order you wish to discuss these main ideas (traits)
This organization needs to be presented in your introduction, preferably as the last sentence of your introduction in the thesis statement.
Note: your thesis is generally the last sentence in your introduction, but it not a requirement.
Follow this structure throughout the rest of the essay.
Always check to see if your main ideas/topic sentences, in each paragraph, relate back to your thesis statement.
Compose 5 well-developed paragraphs that support a clear thesis statement that is arguable.
5 paragraph minimum
introduces your essay and presents your thesis
three body paragraphs
Each paragraph contains one of your chosen admirable traits about your subject
expressed in a topic sentence in your paragraph
Each trait needs to transition to the next one in the next paragraph
look to your chosen pattern of development
rephrases your traits into one last paragraph
reflects the earlier thesis, but with the knowledge of your traits expressed throughout the essay
This essay is a basic form of an argument essay. The essay should make an argument such as that the person or character selected is worthy of admiration because of the traits selected.

5.Hi, i have a task where i need to calculate the 3 months weighted moving average for May 2021, The
eight should be based on the count of sales for the previous period, the actual period and the next period.
In the excel you can see the housing data:
sum of prices(K)
sum of the asses value(T)
K/T value (sum of prices/sum of the asses value)
The answer i'm looking for is that for May 2021 the price development in percentage should be 9.5% compared to three month back. To calculate the price development you just divide the K/T value, for example:
period 1 K/T value = 1.4
period 4 K/T value = 1.9
Price development = (1.9/1.4)-1 = 35.7% increase.
So i want to see 9.5% increase on May 2021 compared to 3 months earlier.
7.Directions: You are part of a fireworks crew assembling a local fireworks display.
There are two parts to the fireworks platforms:
rts to the fireworks platforms: one part is on the ground and the
other part is on top of a building. You are going to graph all of your results on one
coordinate plane. Make sure to label each graph with its equation. Use the following
equations to assist with this assignment.
• The function for objects dropped from a height where t is the time in
seconds, h is the height in feet at time it t, and 0 h is the initial height is
0 ht t h ( ) 16 =− + .

Respond to the following items.
1. While setting up a fireworks display, you have a tool at the top of the
building and need to drop it to a coworker below.
a. How long will it take the tool to fall to the ground? (Hint: use the first
equation that you were given above, 2
0 ht t h ( ) 16 =− + . For the building’s
height, use the height of the building that you estimated in Task 1.)
b. Draw a graph that represents the path of this tool falling to the
ground. Be sure to label your axes with a title and a scale. Your graph
should show the height of the tool, h, after t seconds have passed.
Label this line “Tool”.
8.I need help with my English essay that is discussing how effective communication can be portrayed in different ways using
different ways using 2 speeches we analyzed in class and one of our choice. Here is my introduction: What is effective communication? To most people, effective communication is merely just exchanging information, but in order for communication to be effective, it must reach a deeper level of understanding from both sides. Effective communication must be both understood by the audience and conveyed clearly by the speaker. The audience has to be able to understand a person’s emotions and intentions behind their perspective of the topic. Although there are many ways for a person to achieve the skill of effective communication, the process of epitomizing one’s point of view is not always the easiest task to master. After analyzing various speeches, it is evident that effective communication is most clearly displayed through the speaker’s ability to know the audience as well as establishing themselves as an erudite on the topic in order to alter the opinions of the audience.
