Chapter 3 Assignments P13.Consider a reliable data transfer protocol that uses only negative acknowledgments. Suppose the sender sends data infrequently. Would a NAK-only protocol be preferable to a protocol that uses ACKs? Why? Now suppose the sender has a lot of data to send and the end-to-end connection experiences few losses. In this second case, would a NAK-only protocol be preferable to a protocol that uses ACKs? Why? Answer: In a NAK only protocol, the loss of packet x is only detected by the receiver when packet x+1 is received. That is, the receivers receives x-1 and then x+1, only when x+1 is received does the receiver realize that x was missed. If there is a long delay between the transmission of x and the transmission of x+1, then it will be a long time until x can be recovered, under a NAK only protocol. On the other hand, if data is being sent often, then recovery under a NAK-only scheme could happen quickly. Moreover, if errors are infrequent, then NAKs are only occasionally sent (when needed), and ACK are never sent – a significant reduction in feedback in the NAK-only case over the ACK-only case. P23. We have said that an application may choose UDP for a transport protocol because UDP offers finer application control (than TCP) of what data is sent in a segment and when. a. Why does an application have more control of what data is sent in a segment? b. Why does an application have more control on when the segment is sent? Answer: a) Consider sending an application message over a transport protocol. With TCP, the application writes data to the connection send buffer and TCP will grab bytes without necessarily putting a single message in the TCP segment; TCP may put more or less than a singe message in a segment. UDP, on the other hand, encapsulates in a segment whatever the application gives it; so that, if the application gives UDP an application message, this message will be the payload of the UDP segment. Thus, with UDP, an application has more control of what data is sent in a segment. b) With TCP, due to flow control and congestion control, there may be significant delay from the time when an application writes data to its send buffer until when the data is given to the network layer. UDP does not have delays due to flow control and congestion control.

I．Read the following passages and sum up its point + support 1. Benefits of Writing the Traditional Essay掌握常见短文写作的好处 Writing a traditional essay offers at least three benefits. First of all, mastering the traditional essay will help make you a better writer. For other courses, you'll often do papers that will be variations on the essay form-for example, examination essays, reports, and research papers. The basic structure of the traditional essay, with its emphasis on a clear point and well-organized, logical support, will help with almost every kind of writing that you have to do. Second, the discipline of writing an essay will strengthen your skills as a reader and listener. As a reader, you'll become more critically aware of other writers' ideas and the evidence they provide (or fail to provide) to support those idea;. Essay writing will also help you become a better speaker. You'll be more prepared to develop the three basic parts of an effective speech一an appealing introduction, a solidly developed body, and a well-rounded conclusion一because of your experience writing three-part essays. Most important, essay writing will make you a stronger thinker. Writing a solidly reasoned traditional essay requires mental discipline and close attention to a set of logical rules. Creating an essay in which there is an overall thesis statement and in which each of three supporting paragraphs begins with a topic sentence is more challenging than writing a free-form or expressive paper. Such an essay obliges you to carefully sort out, think through, and organize your ideas You'll learn to discover and express just what your ideas are and to develop those ideas in a logical, reasoned way. Traditional essay writing, in short, will train your mind to think clearly, and that ability will prove to be of value in every phase of your life. 2. Writing as a Skill写作是一种技能 A sure way to wreck your chances of learning how to write competently is to believe that writing is a "natural gift" rather than a learned skill. People with such an attitude think that they are the only ones for whom writing is unbearably difficult. They feel that everyone else finds writing easy or at least tolerable. Such people typically say, "I'm not any good at writing" or "English was not one of my go od subjects” They imply that they simply do not have a talent for writing. While others do. The result of this attitude is that people try to avoid writing, and when they do write, they don't try their best. Their attitude becomes a self-fulfilling prophecy: Their writing fails chiefly because they have brainwashed themselves into thinking that they don't have the "natural talent" needed to write. Unless their attitude changes, they probably will not learn how to write effectively. A realistic attitude about writing must build on the idea that writing is a skill. It is a skill like driving, typing, or cooking. and, like any skill, it can be learned. If you have the determination to learn, this book will give you the extensive practice needed to develop your writing skills. Many people find it difficult to do the intense, active thinking that clear writing demands. (Perhaps television has made us all so passive that the active thinking necessary in both writing and reading now seems harder than ever.) It is frightening to sit down before a blank sheet of paper and know that an hour later, nothing on it may be worth keeping. It is frustrating to discover how much of a challenge it is to transfer thoughts and feelings from one's head onto a sheet of paper. It is upsetting to find that an apparently simple subject often turns out to be complicated. But writing is not an automatic process: We will not get something for nothing and we should not expect to. For

Assignment 1 Ocean Carriers MScEcon 2014 Spring RC. LI (SID: ********) I Should Ms Linn purchase the $39M capsize? Make two different assumptions. First, assume that Ocean Carriers is a U.S. firm subject to a 35% statutory (and effective) marginal tax rate. Second, assume that Ocean Carriers is domiciled in Hong Kong for tax purposes, where ship owners are not required to pay any tax on profits made overseas and are also exempted from paying any tax on profit made on cargo uplifted from Hong Kong, i.e., assume a zero tax rate. Assumptions: 1 Use constant discount rate of 9%. 2 New ships depreciate on a straight-line basis over 25 years with a salvage value of zero. 3 The market value of the ship in the second-hand market is the same to book value including capital expenditure for maintenance. 4 After the year 2005, the new ship would continue operate at E[Daily Hire Rate] adjusted. 5 Operation cost is initially 4,000 per day, and grows at the rate 4%. 6 Net Working Capital is initially 500,000 and grows with inflation. 7 Scrap value at 2017 is $5M, and adjusted by inflation rate when scrapping in other years. 8 There is no default risk. 9 There is no side effect such as erosion and synergy. 10 When scrapping the ship at special survey year, the firm does not spend money on maintenance. At year 2027 the firm does not sell it in second-hand market and only scrap it. 11 The firm would recover Net Working Capital before selling or scrapping the ship. 12 Calculate one year as 365 days.
