You will respond in paragraph format with correct spelling and grammar expected for each paragraph. Feel free to have more than one paragraph for each item, although in most instances a single paragraph response is sufficient. If you reference material in addition to what is available in the textbook it must be appropriately cited in your work using either APA or MLA including a references cited page. The use of Wikipedia.com is not a recognized peer reviewed source so please do not use that as a reference. When responding about individuals it is necessary to indicate a year or time period that the person discussed/developed their particular ethical theory so that you can look at and appreciate the historical background to the development of ethical theories and decision making. Respond to the following sixteen items. (They are in random order from your reading) 1. Francis Bacon 2. Isaac Newton 3. Prima Facie Duties – Why do they exist? LIST AND DEFINE ALL TERMS 4. Hippocrates 5. W.D. Ross – what do the initials stand for in his name and what was his contribution to the study of ethics? 6. Microallocation – define the term and provide an example separate from the book example (You should develop your own example rather than looking for an online example; this will use your critical thinking skills. Consider an application to your own profession as microallocation is NOT limited to the medical field.) 7. Deontology – Discuss at length the basic types/concepts of this theory 8. Thomas Aquinas – 1) Discuss the ethical theory developed by Aquinas, 2) his religious affiliation, 3) why that was so important to his ethical premise and 4) discuss the type of ethical issues resolved to this day using this theory. 9. Macroallocation – define and provide an example separate from the book example (You should develop your own example rather than looking for an online example; this will use your critical thinking skills. Consider an application to your own profession as macroallocation is NOT limited to the medical field.) 10. David Hume 11. Rodericus Castro 12. Plato and “The Republic” 13. Pythagoras 14. Teleology – Discuss at length the basic types/concepts of this theory 15. Core Values – Why do they exist? LIST AND DEFINE ALL TERMS 16. Develop a timeline that reflects the ethical theories as developed by the INDIVIDUALS presented in this assignment. This assignment is due Saturday March 14th at NOON and is graded as a homework assignment. Grading: Paragraph Formation = 20% of grade (bulleted lists are acceptable for some answers) Answers inclusive of major material for answer = 40% of grade Creation of Timeline = 10% of grade Sentence structure, application of correct spelling and grammar = 20% of grade References (if utilized) = 10% of grade; references should be submitted on a separate references cited page.

1 BACKGROUND The new generation of enhanced mid core PICs such as the 16F1847 and the 12F1840 have an inbuilt temperature sensor. This sensor consists of a current source which flows through four diodes in series and the voltage drop across the diodes which is proportional to temperature can be measured by internally connecting the sensor to the ADC and determining the temperature based on the ADC value In this assignment the temperature sensor is used to create a simple thermometer application and to create an alarm should the sensor go outside the set value. Assignment Details 1) Determine the register settings needed to switch the sensor on and connect the temperature sensor to the ADC. Using appropriate values for Vref+ and Vref- display the ADC count value on the 7 segment display. 2) With reference to Microchip Application Note AN1333, “Use and Calibration of the Internal Temperature Indicator” (DS01333) determine an appropriate algorithm to convert from the ADC value to the temperature in degrees centigrade and implement it using a lookup table or otherwise. Display this value on the 7 segment display. Additional marks will be given for accuracy, calibration and averaging the temperature readings to give a more accurate, and a more stable temperature reading. . 2 In order to meet the specification the following will be required. i) Selection of appropriate microcontroller to meet the requirement of the task. ii) Development of an assembly language program to control the operation of the embedded system. iii) Thorough testing to ensure correct operation of the system. iv) Produce a project report to evidence all of the above. Follow Report Requirements (20 pages max) 1) Introduction – Clearly state the scope and aims and objectives of the project: Include Aims and Objectives, i.e. break down the project into smaller attainable aims and objectives for example one objective could be to develop a program to control the LED display. If all objectives are met then the overall project should have been completed. 2) Theory – Include any relevant theory 3) Procedure, Results Discussion – The report should show a methodical, systematic design approach. The microcontroller kits in the laboratory can be used as the hardware platform, however circuit diagrams should be included in the report and explanations of operation is expected. 4) Include flowcharts and detailed explanations of software development. Include appropriate simulation screen shots. Show and discuss results e.g. ADC program, LED program, etc. Include final/complete program. Were results as expected, do they compare favourably with simulated results, what could be done to improve the operation and accuracy of the system? 5) Conclusion – Reflect back on the original aims and objectives.

ESL 091 Cause and Effect Worksheet 1: Steps 1-4 of the Writing Process Name ______________________________ Class___________ Section______ THE WRITNG PROCES: STEPS 1, 2, 3, AND 4 Step 1: THINKING. Your first essay assignment is to write an Explaining/Evaluation essay about a restaurant. Begin the writing process by thinking about your topic. Think! Think! Think! Step 2: BRAINSTORMING. The purpose of brainstorming is for you to write down all of the ideas, thoughts, and pieces of information that you think about your topic before you forge them. You can use one of three brainstorming techniques, but the journalist’s questions will get you’re the most information to write an 800-word essay. We talked about three brainstorming techniques: 1) Writing down all your thoughts in a list format. 2) Creating an idea map. 3) Asking and answering the journalist’s questions that are important for your topic: Who? What? Where? When? Why? How? As you are thinking and writing down your ideas, ask yourself the following questions about your cause and effect topic: A. What is the cord cause of issue? Is there more than one cause? What is the immediate (first) effect of the cause? Does this first effect also become a cause? If so, what effect does this new cause have? Are there other effects caused by the core cause? What are they? Do they also become new causes with their own effects? If so, what are they?

Writing a Working Thesis. First, decide who your audience is and what your purpose is. A. Audience: Think about who would be interested in reading your cause and effect topic. If you say: “Anyone who is interested in my topic,” your audience is too big. Think about who might benefit from knowing the information you are writing about. Be specific. _____________________________________________________________________________________ B. Purpose: The purpose in your writing is the message you want your audience to know about the topic. You can find out your purpose by asking yourself what you want your audience to know about the topic and put that in a complete sentence. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ C. Working Thesis: A thesis is a statement that tells your audience what your overall attitude is about your topic. In a cause and effect essay, your thesis would state the core causes and major effects of the core cause. A working thesis can change as your essay changes and improves. Your thesis should include: 1) The core cause/s 2) The major effects that you will discuss in the body of the paper. Example: CORE CAUSE/S MAJOR EFFECTS Fast food and lack of movement are the core reasons for obesity, which results in disease such as heart trouble, diabetes, and joint failure. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ ________________________________________________________________________ **********Save this worksheet and bring it to the next class meeting.***********

Essay Assignment: Due December 6th, on Blackboard by 11:59 PM. Note: At least one draft (hardcopy, handed up in class) should be given to the instructor one week before due date (last date to give instructor draft is 1st December). If draft is not given, 20% will be taken off final grade for essay. Assignment Objective: This assignment is intended to provide you with the opportunity to reflect upon the course and material over the semester. Instructions: In this essay you will need think back prior to the semester and construct how you would have described ‘the self.’ Consider as your guide the many ways that the self has been studied over the course of the semester. For instance, you might consider the ways we have discussed: (1) the nature of the soul, (2) personal identity, (3) the relationship to others, (4) the ‘racial’ or ‘gendered’ self, (5) the self and freedom, (6) the social influences (economics, technology, and consumerism, for example) upon your self-development, etc. You should select one to two dimensions of the self and provide a description of what you thought about those prior to the course. Then, give a description of what you think about that or those dimension(s) of the self now. Be sure to reference the course material, either through the literature, or an author, or a driving concept from the course that you can explain in reference to the concept(s) you now hold. Within your discussion provide a comparison of what you thought prior to the course to what you now think of those dimension(s) of the self. In what ways has your conception of the ‘self’ changed, stayed the same, become enriched (or not). Be sure to give some explanation as to what has changed, or has not changed, and in what ways. Format: The paper should be in Times New Roman font, size 12, and double spaced. It should be about 1,200 words (approx. 4-5 pages). You will be required to have a bibliography and a cover page which includes the following: 1) The title of your paper. 2) Your name. 3) Your Student ID number. Citations: The recommended style of citation is Chicago (please see Blackboard for guidelines). You can use other styles if you like but the most important thing is to remain clear and consistent in the referencing style that you use. Please use at least 2-3 citations. Instruction for upload: Please upload it online onto Blackboard on the tab on the left hand side, entitled ‘Final Essay’ before midnight on December 6th. No hard copy is needed, but, as stated above, you will be required to give a hard copy of the draft at least one week before to the instructor. Grading: The final essay will be graded on: (1) how the instructions of the assignment were followed, (2) the accurateness and clarity in descriptions of course material (authors, core concepts, arguments, etc.), (3) the precision/correctness of writing, and (4) accuracy of referencing style.

Figure 2: Given: Pollock { Spring 2012 Determining the gravitational force between two rods: (a) Consider a thin, uniform rod of mass m and length L (and negligible other dimensions) lying on the x axis (from x=-L to 0), as shown in g 1a. Derive a formula for the gravitational eld \g" at any arbitrary point x to the right of the origin (but still on the x-axis!) due to this rod. (b) Now suppose a second rod of length L and mass m sits on the x axis as shown in g 1b, with the left edge a distance \d" away. Calculate the mutual gravitational force between these rods. (c) Let's do some checks! Show that the units work out in parts a and b. Find the magnitude of the force in part a, in the limit x >> L: What do you expect? Brie y, discuss! Finally, verify that your answer to part b gives what you expect in the limit d >> L. ( Hint: This is a bit harder! You need to consistently expand everything to second order, not just rst, because of some interesting cancellations) Fig 1a Fig 1b L m +x x=0 L x=0 x=d m Fig 1a Fig 1b L m +x x=0 L +x x=0 x=d L m m Back to Problem List 8 5 { GRAVITATION Last Updated: July 16, 2012 5.8 Potential energy { Check your answer! Given: Pollock { Spring 2011 On the last exam, we had a problem with a at ring, uniform mass per unit area of , inner radius of R, outer radius of 2R. A satellite (mass m) sat a distance z above the center of the ring. We asked for the gravitational potential energy, and the answer was U(z) = ?2Gm( p 4R2 + z2 ? p R2 + z2) (1) (a) If you are far from the disk (on the z axis), what do you expect for the formula for U(z)? (Don’t say \0″ – as usual, we want the functional form of U(z) as you move far away. Also, explicitly state what we mean by \far away”. (Please don’t compare something with units to something without units!) (b) Show explicitly that the formula above does indeed give precisely the functional dependence you expect.

(b) A half-in nite line of mass on the x-axis extending from x = 0 to x = +1, with uniform linear mass density . There are two general methods we use to solve gravitational problems (i.e. nd ~g given some distribution of mass). (a) Describe these two methods. We claim one of these methods is easiest to solve for ~g of mass distribution (a) above, and the other method is easiest to solve for ~g of the mass distribution (b) above. Which method goes with which mass distribution? Please justify your answer. (b) Find ~g of the mass distribution (a) above for any arbitrary point outside the cylinder. (c) Find the x component of the gravitational acceleration, gx, generated by the mass distribution labeled (b) above, at a point P a given distance z up the positive z-axis (as shown).

(So the left end is at (-L/2, 0,0) and the right end is at (+L/2,0,0) Assume the mass density  (which has units of kg/m)is not uniform, but instead varies linearly with distance from the origin, (x) = cjxj. (a) What is that constant \c” in terms of M and L? What is the direction of the gravitational eld generated by this mass distribution at a point in space a distance z above the center of the rod, i.e. at (0; 0; z) Explain your reasoning for the direction carefully, try not to simply \wave your hands.” (The answer is extremely intuitive, but can you justify that it is correct?) (b) Compute the gravitational eld, ~g, at the point (0; 0; z) by directly integrating Newton’s law of gravity, summing over all in nitesimal \chunks” of mass along the rod. (c) Compute the gravitational potential at the point (0; 0; z) by directly integrating ?Gdm=r, sum- ming over all in nitesimal \chunks” dm along the rod. Then, take the z-component of the gradient of this potential to check that you agree with your result from the previous part. (d) In the limit of large z what do you expect for the functional form for gravitational potential? (Hint: Don’t just say it goes to zero! It’s a rod of mass M, when you’re far away what does it look like? How does it go to zero?) What does \large z” mean here? Use the binomial (or Taylor) expansion to verify that your formula does indeed give exactly what you expect. (Hint: you cannot Taylor expand in something BIG, you have to Taylor expand in something small.) (e) Can you use Gauss’ law to gure out the gravitational potential at the point (0; 0; z)? (If so, do it and check your previous answers. If not, why not?)

For this (admittedly very unusual!) planet, suppose the gravitational eld strength inside the planet turns out to be independent of the radial distance within the sphere. Find the function describing the mass density  = (r) of this planet. (Your nal answer should be written in terms of the given constants.) (b) Now, determine the gravitational force on a satellite of mass m orbiting this planet at distance r > R. (Use the easiest method you can come up with!) Explain your work in words as well as formulas. For instance, in your calculation, you will need to argue that the magnitude of ~g(r; ; ) depends only on r. Be explicit about this – how do you know that it doesn’t, in fact, depend on  or ? (c) As a nal check, explicitly show that your solutions inside and outside the planet (parts a and b) are consistent when r = R. Please also comment on whether this density pro le strikes you as physically plausible, or is it just designed as a mathematical exercise? Defend your reasoning.

(This minimum speed is called \escape velocity”) Is the size you computed typical for asteroids in our solar system? Back to Problem List 13

CIS CSC 315 01 Middleware for Enterprise Architecture – Winter 2014 Microsoft Project Objectives: Enterprise resource planning (ERP) is business management software—usually a suite of integrated applications—that a company can use to store and manage data from every stage of business, including: • Product planning, cost and development • Manufacturing • Marketing and sales • Inventory management • Shipping and payment ERP provides an integrated real-time view of core business processes, using common databases maintained by a database management system. ERP systems track business resources—cash, raw materials, production capacity—and the status of business commitments: orders, purchase orders, and payroll. The applications that make up the system share data across the various departments (manufacturing, purchasing, sales, accounting, etc.) that entered the data. ERP facilitates information flow between all business functions, and manages connections to outside stakeholders. Put together a PowerPoint presentation (about 15 minutes) addressing the issues below. ALL team members will participate in the presentation. The only “deliverable” is the PowerPoint presentation itself. The presentations will be the last day of class for the semester. 13-Discuss a failure or two.
