2.In this problem and the next one, we’re going to make a very simple spam checker program by just looking ...

ooking at how likely a given email is to be spam based on the words it contains. In particular, in this problem we’re going to count how often words are present in spam emails within some set of training data (which here means a set of emails that have already been marked as spam or not spam manually). We have already started to write a function spam_score(spam_file, not_file, word), which takes in two filenames, along with a target word (a lowercase string). Both filenames refer to text files which must be in the same directory as (we’ve provided several such files in The text files contain one email per line (really just the subject line to keep things simple) - you can assume that these emails will be a series of words separated by spaces with no punctuation. The first file contains emails that have been identified as spam, the second contains emails that have been identified as not spam. Since you haven’t learned File I/O yet, we’ve provided code that opens the two files and puts the data into two lists of strings (where each element is one line - that is, one email). You then must complete the function, so that it returns the spam score for the target word. The spam score is an integer representing the total number of times the target word occurs across all the spam emails, minus the total number of times the word occurs in not-spam emails. Convert all words to lowercase before counting, to ensure capitalization does not throw off the count.

3.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.

5.3A(g) + X(g) → Z(g) ΔH° = -480 kJ/molrxn The equation shown above represents an exothermic reaction between A(g) ...

reaction between A(g) and X(g). What is the amount of heat released when 10 mol of A(g) reacts with an excess X(g) ? ΔH A -236kJ X -136kJ Y -167kJ Using the heats of formation found in the table above, calculate ΔH for the reaction below. 6A(aq) + 7X(g) → 6Y(l) Y + 2X → 4Z ΔH=-4 A + 3B → 2Z ΔH=-2 A → X +C ΔH=7 Using the thermodynamic data above, determine ΔH for the reaction below. 2C+ 6B → Y When 0.3 moles of A(s) (4 grams) is dissolved in 12 grams of water at 23°C, the temperature of the water increases to 31°C. The specific heat of water is 4.18 J/g°C. Calculate ΔH in kJ/mol. Report your answer to 1 decimal place.

6.We are going to design a synchronous state machine that implements a timer of ten seconds. For this, we will ...

we will use a 4-bit register (with parallel input and output) as memory element of the state machine, a 16-byte ROM memory to implement the next state logic and output logic, and a 4-bit binary counter to count the time. Following is an (incomplete) sketch of the circuit to be used. Note that the registrar is already in its data entry enabled, while the counter is already with its “load” input disabled. Also note that we have a 1 Hz clock signal and also a button for “Reset” the register (which must bring the timer to its initial state, as described further up).

8.Above is 2 years and 4 months of actual demand data for a new call center. For example, cell ...

resenets 12,380 calls received in January 2019. Using this data, create two different models for demand forecasting. One combining Exponential Smoothing with Trend, and one combing Exponential Smoothing with both Trend and Seasonality. Ensure you conduct some type of error analysis and try to input adjust factors (such as Alpha) to minimize error. Please clearly indicate at the top of your sheet your selected value for factors (Alpha, Beta, Gamma) and the error analysis metric name and value. In the space below, indicate which model has less error and what you believe that indicates is true about the underlying demand pattern.
