Using the same data as in Example 4.2, design a series PFR reactor with interstage cooling (three separate reactors) to obtain 9% conversion for isomerization of MCP. Use inlet temperatures of 600, 500 and 450°C for the three reactors. Try for an optimal design that follows and is symmetric around the LOMR. Compare the weight of catalyst in your three reactors with that of the single reactor in Example 4.2(f). We suggest solving graphically and/or using numerical integration.

A contractor is constructing a project for which he will be paid in one lump sum upon satisfactory completion of the project. The contractor needs cash to finance the construction and opens a line a credit at their bank (the loan would be repaid at the end of the project). The construction project is expected to last 16 months, and the contractor expects to borrow $100,000 at the beginning of the first month, and at the end of each of the first six months, making a total borrowing of $700,000. The contractor then needs to borrow $250,000 per month at the end of month 7 through 16, for an additional $2,500,000. The owner agrees to pay the contractor the lump sum payment for the project at EOM 20, at which time the contractor will repay the bank. Interest on the contractors outstanding loan balance is 1.5% per month for the first 10 months and then 2% per month until EOM 20. Given this scenario, please answer the following questions. a. What is the minimum contract price for this project to be profitable? b. How would this number change if the interest rates were variable between 1-3% for the first 3 months and 1-5% for the remainder of the project? c. What is a reasonable rate of return for this project? d. How will your answers in a. and b. would change if the rate of return is what is described in c.? 2. What is your preferred method for LCC? Please articulate your thoughts with examples in less than 1 page.

Information Assurance

I need an expert in (Information Assurance) to write 5 summaries about 5 Defcon/blackhates videos. The 5 reviews will be graded and counted as 5 daily standing assignments. The reviews will be turned in on blackboard. Each review needs to be a short discussion of roughly half a page of 12-point font with a 1” margin text.
** Do not copy the talk abstracts that are available online as part of your
summary. If you do so, you will receive no credits for that review**
Several of these conference presentations archived online. I recommend reviewing
videos, slides or audio files from more recent conferences.
