As the example of COPACOBANA [105] shows, key-search machines need not be prohibitive from a monetary point of view. We now consider a simple brute- force attack on DES which runs on COPACOBANA.1. Compute the runtime of an average exhaustive key-search on DES assuming the following implementational details: COPACOBANA platform with 20 FPGA modules 6 FPGAs per FPGA module 4 DES engines per FPGA Each DES engine is fully pipelined and is capable of performing one encryp-tion per clock cycle 100 MHz clock frequency2. How many COPACOBANA machines do we need in the case of an average search time of one hour?3. Why does any design of a key-search machine constitute only an upper security threshold? By upper security threshold we mean a (complexity) measure which describes the maximum security that is provided by a given cryptographic algo- rithm.

 Please complete the attached case studies Case Study #1The Case Study in Unit I (Case Study 2-2: Mowerson Division) is located on pages 83-85 in your textbook. Read the caseand utilize the data included in the case to answer the following questions.1. Discuss whether Jim Wright should have analyzed only the costs and savings that Mowerson would realize in2002.2. For each of the 10 items listed in Wright’s financial analysis, indicate whether:a. The item is appropriate or inappropriate for inclusion in the report. If the item is inappropriate, explain why itshould not be included in the report.b. The amount is correct or incorrect. If the amount is incorrect, state what the correct amount is.3. What additional information about Tri-Star would be helpful to Mowerson in evaluating its manufacturing decision?  Case Study #2The Case Study in Unit III (Case Study 5-1: Celtex) is located on pages 215-216 in your textbook. Read the case andutilize the data included in the case to answer the following questions.1. Calculate the incremental cash flows to Celtex if the consumer products division obtains Q47 from Synchemversus Meas Chemicals.2. What advice would you give Debra Donak?  Case Study #3The Case Study in Unit V will come from the Problems Section of Chapter 9. (Problem 9-2: IPX Packaging) is located onpage 427 in your textbook. Read the case and utilize the data included in the case to answer the following questions.1. Calculate the overhead rate set at the beginning of the year.2. Calculate the amount of over/underabsorbed overhead for the year.3. The company’s policy is to write off any over/underabsorbed overhead to cost of goods sold. Will net income riseor fall this year when the over/underabsorbed overhead is written off to cost of goods sold?

Behavioral Principles Application Presentation: Reinforcement This assignment has you work with your team to determine how reinforcement–both positive and negative–is used within an applied setting.Imagine your team works for a behavior analysis consulting group and has been asked to present on behavioral principles used in a specific setting.Choose one setting in which to apply principles of behavior. Example settings include schools, hospitals, prisons, or businesses.Evaluate the use of various types of reinforcement in the chosen setting.Create a 10- to 12-slide presentation, including detailed speaker notes, that displays your findings and analysis and that proposes ideas for effective reinforcement. We will be working with Schools as our setting, theme is bullying.3 slides Positive and negative punishmentcitations, references and graphics

I need a on You will need to . You will also need to Explore the supply and demand conditions for your firm’s product.a) Evaluate trends in demand over time and explain their impact on the industry and the firm. You should consider including annual sales figures for the product your firm sells.b) Analyze information and data related to the demand and supply for your firm’s product(s) to support your recommendation for the firm’s actions. Remember to include a graphical representation of the data and information used in your analysis. III. Examine the price elasticity of demand for the product(s) your firm sells.a) Analyze the available data and information, such as pricing and the availability of substitutes, and justify how you determine the price elasticity of demand for your firm’s product.b) Explain the factors that affect consumer responsiveness to price changes for this product, using the concept of price elasticity of demand as your guide.c) Assess how the price elasticity of demand impacts the firm’s pricing decisions and revenue growth.

Read the . case study there are 10 recommendations. Choose 3 of the recommendations and identify how IT could be used as part of the implementation of that recommendation. Research in the library how other companies have done something similar for each of your 3 recommendations. Your paper should be at least 3 pages, not counting the title and reference pages. The paper must include at least 3 references from peer-reviewed articles in academic journals. Make sure you have in-text citations and a reference page.  You can include additional references from websites and books.

What are some of the obstacles and/or non-listening behaviors that you exhibit? What are some reasons we “tune people out”? Classify these reasons as internal or external obstacles as well as non-listening behaviors.Review pages 168 through 177 in our textbook for a descriptive list of common communication obstacles and non-listening behaviors.

Class, on the topic of avoidance, I wanted to bring up the concept of approach goals and avoidance goals.   We know that we\’re often more motivated when we\’re running toward something (an approach goal) as opposed to trying to avoid something.   Why do you think this might be the case?    Most goals can be phrased as both an approach goal and an avoidance goal…I might attempt to set an approach goal for a new job, or I could set an avoidance goal to leave my old job.     What makes the difference here, and how might motivation be impacted?about 150 words 

Write an analysis that is at least one page in length where you analyze your own listening effectiveness. Using the textbook to guide you, analyze your strengths and weaknesses in terms of the text\’s guidelines for effective informational listening and effective rational listening. Identify two listening skills you would like to improve and describe how you plan to develop greater competence in each.

1.Suppose you sell short 100 shares of IBM currently selling at $120/share. What is your maximum possible loss? What is your maximum loss if you place a stop- buy order at $128/share? 2. Suppose that British Petroleum (BP) is selling at $20 per share. You buy 1,000 shares using $15,000 of your own money and borrow the remaining amount on margin from your brokerage company. The broker’s margin rate is 8%. a) What is the percent increase in the net worth of your brokerage account if the price of BP immediately changes to (i) $22; (ii) $20; (iii) $18? b) Assume a year has passed. If the maintenance margin in 25%, how low can BP’s price fall before you get a margin call from your broker? c) It’s now a year later. Wat is the percent increase in the net worth of your brokerage account if the price of BP changes to (i) $22; (ii) $20; (iii) $18? 3. If you place a stop order to sell 100 shares of stock at $55 when the current price is $62, how much will you receive for each share if the price drops to $50? (a) $50 (b) $55 (c) $54.87 (d) can’t tell from the information given
