Answer the following questions on the same page: 15. Based on the location and magnitude of your earthquake, speculate on the type of damages your earthquake might have caused. 16. Now compare this to the Mercalli Intensity scale. What classification is your earthquake based on this scale? 17. How did the different waves (P, S & Surface Waves) assist you in determining the epicenter and the amount of damage caused? 18. Was your location in an area prone to earthquakes? Speculate on what might have caused this earthquake (be specific). 19. Why is it so difficult for geologists to predict when and where an earthquake will occur? 20. What connections can you make between the behavior of the seismic waves and the Earth's interior? 21. Make sure your name is ON your document before submitting. Tips and hints can be found here (Links to an external site.). This assessment is adapted from "Virtual Earthquake" by Gary Novack, originally found here (Links to an external site.).

How does idealism and self-interest produce different foreign policies? What types of foreign policies are associated with each? Must these two positions always generate different foreign policies? And is one (idealism or self-interest) always superior to the other? Address this question by incorporating information and/or arguments from your assigned readings over the last three weeks. As with all of your open essay assignments, answers should be at least two paragraphs long, and there is no maximum length.

Unit Aim: The aim of this online engineering course unit is to develop your skills and knowledge on how engineering companies operate, and the role of professional engineers within those companies.
Read through the situation and objectives below and submit the required deliverables for the assignment. Background: AAA Northeast is one of the regional clubs comprising the American Automobile Association. AAA Northeast covers Rhode Island, Connecticut, Massachusetts, and portions of New York and New Jersey. The American Automobile Association has 58 million members in the US and Canada. They offer services such as roadside assistance, maps, and various discounts as part of their services. Roadside assistance is a costly benefit, particularly towing. Members who frequently use roadside assistance are less desirable. AAA also offers other paid services at highly competitive prices. They also offer insurance, travel, and banking/loan products. AAA would like to increase the penetration of these services. A member may have a standard membership or a premium membership covering themselves and optionally additional household members. Many of AAA members typically have a long tenure with the club. Project objectives: Provide a market segmentation of AAA members (or member households) that allows AAA Northeast to better serve its members. They would use this analysis to: Better anticipate the needs of members Customize communications and offerings to various segments Expend more effort driving the acquisition and renewal of desirable members We'll work with the members at the household level. Methodology: There are several dimensions of revenue as well as cost. Revenue: Products Purchased Tenure Number of members in the household Level of membership Cost: Use of roadside service Frequency of use Cost to service Summarize data to the household level. Divide your data into training and validation sets. Develop a series of “look-alike” models to determine the probability of purchasing each product. Validate your models. Develop models to predict the likelihood of using roadside service as well as the total cost of roadside usage. Join your training and validation sets. Score all the members that do not have the purchase of a product with the probability of purchase. If they have purchased the product, score them a 1. Score them on the likelihood of roadside usage and the expected cost (in the next 12 months). Use your model results to cluster/segment the members. Use a small number of clusters (4-6). You may include tenure (length of membership), number of members in the household, and the sum of your product probabilities in your clustering as well as each model score. Be creative. Any numeric variable can potentially be used. If you have performance issues you may subsample the data. Expected deliverables: A slide deck describing your findings and the methodology that you used. You should describe your segments (clusters) in non-technical terms. You should attempt to make recommendations as to how they might provide value to AAA Northeast. Data Sets & Sample Decks Here is the data needed for the project and a few sample decks on similar topics. These are provided only for your reference. (Feel free to structure your presentation based on your findings and analysis. You are discouraged to copy from the samples and use them as is). Final Project Training MaterialsLinks to an external site. Submission instructions: Upload your presentation to the platform here. Your presentations will be graded using a rubric. Refer to the rubric listed below and also on the platform. Reach out to your course leaders across the seven weeks anytime for any support in completing the deck.

Lab 4 Assignment Details: Drug dissolution from an immediate release vs modified release preparation There are four tasks that need to be completed as part of your assignment for this lab session. Plot the calibration graph and using linear regression analysis, determine the equation ofthe line and linear correlation coefficient (10 marks). 2. Calculate the % drug released at each time point on the basis of the theoretical dose of drug (200mg). Present your findings as arithmetic mean ± standard deviation for both the immediate release and the modified release preparation. (20 marks) 3. Determine a possible model to describe the drug release/drug dissolution from the two preparations studied by plotting the following relationships (use mean values for this): (a) mg drug released = f(time) (b) In (mg drug released) = f (time) (c) mg drug released = f (square root of time) (d) mg drug released = f (cube root of time) [zero order process] [first order process] [Higuchi square root law] [Hixon-Crowell cube root law] The most likely model to describe the drug release would result in a straight line in one of these four graphs. (Note, however, that due to the complexity of the dissolution process the models often only describe some part of it i.e. a straight line is obtained in between a certain time span only.) On the basis of the most suitable model, for the modified release formulation predict the times, where 50%, 75% and 95% drug would have been released, using the correct numerical expression/time law (30 marks) 4. Discuss briefly (max. 400 words) the effect of formulation design on the drug release pattern exhibited by the two dosage forms (40 marks 9
