Define the types of ultrasound pressure waves Solution Ultrasound pressure waves that are widely used are --------- l. Longitudinal wave where the motion of the molecules in the medium is parallel to the direction of wave propagation. 2. Shear wave where particles move at right angles to the movement of the wave. In biological tissues it occurs only in the bones(solid tissue). Two more waves are also used and these are -------- 1. Surface wave which travels along the curved or flat surface of thick solids without influencing the bulk of medium below the surface. 2. Plate wave which are elastic waves whose particle motion lies in the plane that contains the direction of wave propagation and the plate normal..

What are the main motives for establishing an international joint venture? Illustrate your answer by drawing upon the case study of Renault & Nissan. Solution Defining the ‘motive’ of international joint venture The study of motives of international joint ventures in international business and marketing literature is consistent and substantial (Hyder, 1999; Tatoglu, 2000; Banai et al 1999; Fahy et al 1998; Tatoglu and Glaister 1998; Wong 1998). Motives of IJV formation have been assessed in different country contexts (for example UK, Sweden, Turkey, Hungary, Hong Kong, Russia etc). The examination of IJV literature however suggests that IJV studies suffer from an imperfect understanding of the term ‘motive’. None of the studies examined in this paper has made any attempt to define the term ‘motive’. It appears that researchers and authors in prior studies have assumed that ‘motive’ is a well-understood term by the academic audience including researchers, readers and respondents. The available evidence of multiple interpretations in different studies however indicated subjective and fractured understanding of this key concept. The lack of definition of motive is a critical oversight in IJV research effort. It has contributed to the possibility of multiple interpretations. It is argued that the absence of a consistent interpretation and definition of the term motive has been a key contributory factor to the slow progress of research on IJV motives. A lack of universally accepted definition has led to interpretation inconsistencies in different IJV studies. While the precise understanding of ‘motive’ as a fundamental concept is essential in any investigation of IJV motives, it has received little or no attention in earlier literature. It is argued that the comprehensive definition of ‘motive’ is central to bringing about a balanced understanding to this area of research EXISTING INTERPRETATIONS: The dominant interpretation of motive in most studies borders the notion of ‘reasons’ of choosing IJV governance structure. The seminal work of Tomlinson (1970, 192) sets the tradition of interpreting motives as reasons for example ‘favorable past association’ was reported as the single most important reason followed by ‘facilities’, ‘resources’, and ‘partner status’. In other studies, motive is also interpreted in slightly different but related manner. Interpretation of Hyder and Ghauri (1989) and Hyder (1999) suggest the notion of benefits rather than the dominant interpretation of ‘reason’ implied by the term motive. Subsequent studies however by Glaister (1996), Fahy et al (1998), Wong (1998), Tatoglu (2000) seem to continue with the interpretation of Tomlinson although without any explicit acknowledgement. The problem of multiple interpretations is further exacerbated by inconsistent and often vaguely stated theoretical approaches of IJV studies. The following section sets out to define the concept of ‘motive’ from a resource-based perspective. It i.

9 & 10 9. The study of behavioral finance has best helped explain which of the following investor behav- iors? (a) Investors are often unable to short-sell unfavorable stocks. (b) Investors often create undiversified portfolios (c) Investors tend to sell their losing stocks and retain stocks that have capital gains. (d) Investors are generally too slow to update their beliefs in the face of new evidence 10. Briefly discuss some of the important findings of behavioral finance studies. Solution 9) d is correct Behavioral finance has been very helpful in explaining that inveatinv are too slow to update their beliefs in the face of new evidences. 10) Behavioral finance has focused on two crucial areas and they are attitude towards risk and beliefs about probability. It tells us that security mispricing can result from the investor\'s attitude towards risk and how they asses probability. It deals with behaviour of investors at the time of capital gain and capital loss. It tells us that investors are either risk averse or risk loving that is they do not behave rationally..

Will China\'s economic success continue into the foreseeable future? If not, what might derail it? Solution No chinese economics success may not be continue into the foreseeable future because of the following reasons. 1) From the past 25 yeras china is having large number of youth who are aged between 21-35 .Now the Youth population is slowing decling and the people who are older are increasing. 2) China is having a big threat in the form of India. India is trying to emerge as a developed and is moving its steps in that way. It is also developing in every aspect and growth rate is also high. India and China both are most populous countries in the world. They both are trying to emerge as a super power. 3) Chinese market is decling as people are having a negativity that there goods are of low quality and the manufacturing industries are trying to maintain distance from them. 4) All the World knows china manipulates its currency for exporting there goods. 5) All the worlds are negative towards due to various political reasons. 6) Now as it is the time globalization China is still a closed economy which is not good for that country. So all these factors will effect china which will have impact on its economy and its growth..

Redundant Array of Inexpensive Tape (RAIT) is used to back up systems by means of a tape array that stripes the data across the tape. Answer A is incorrect because RAID is not typically used for backup. Answer C is incorrect because JBOD (Just a Bunch of Disks) offers no backup or fault tolerance.

4) Production in the country of StockVille can be characterized by the following function: Y= 2K0.20.8 and that Stockville initially has 200 units of labor and 1000 units of capital. a) b) c) d) Calculate the marginal product of labor and marginal product of capital for StockVille. Show with calculus that the production function exhibits diminishing returns to capital. Calculate the total payments to labor and capital in StockVille. Suppose that in Stock Ville there is a large increase in investment that adds a lot more capital to the economy. What happens to the rental rate of capital and real wage rate in StockVille? Briefly explain 2 e Aain suppose that in StockVille there is a large increase in investment that adds a lot more capital to the economy. What happens to the income shares of capital and labor in this economy? No math is necessary but it may help to see the answer if you pretend that capital increased from 1000 to 1500 while the amount of labor stayed the same. f) In the production function for Stock Ville briefly explain what the \"2\" represents. Solution a) Marginal product of labor is the derivative of production function wrt labor and Marginal product of capital is the derivative of production function wrt capital. MPL = 2x0.8xK^(0.2)xL^(0.8-1) = 1.6(K/L)^0.2. Similarly, MPK = 0.4(L/K)^0.8 b) We see that MPK = 0.4(L/K)^0.8. This implies that for any values of K and L > or = 0, MPK is positive. Now find the derivative of MPK with respect to K. d(MPK)/dK = 0.4*(-0.8)*(L^0.8)*(K^-1.8). = -0.32(L^0.8)*(K^-1.8) For any values of K and L > or = 0, MPK is now negative. This shows that as capital rises MPK falls. This is basic postulate of diminshing marginal returns to capital c) At L = 200 and K = 1000, MPK is 0.4*(200/1000)^0.8 = 0.1104. For 1000 units of capital, payment made to capital is 110.4. At 200 units of labor, MPL is 1.6*(1000/200)^0.2 = 2.2076. For 200 units of labor, payment made to labor is 2.2076*200 = 441.52. d) At the current rate, MPL > MPK. Adding more capital will reduce the rental price of capital because its supply is increased and capital owners will be willing to accpet a lower rate as well. Real wage will increase as less labor is used and so MPL will increase. e) Income share of capital and income share of labor both will increase if labor employed is unchanged. This is because rental rate of capital has reduced due to low MPK while K is increased. MPL has K in the denominator so a rise in K will increase MPL. Labor share in income rises essentially. Capital share rises because K rises even though MPK falls f) 2 is the technology parameter that indicates how much of the production is increased due to technology..

PROGRAM 2 – Fraction Class Problem For this programming assignment, you are to implement the Fraction class design given below (and discussed in class). You are also to develop an appropriate test driver that thoroughly tests the class. Fraction Class Design Implement the following class design. Make sure to use implement the methods to have the same names as given below, with the same number and types of parameters. public class Fraction { private int numer; private int denom; // alternate constructor public Fraction(int numer, int denom) throws InvalidDenominatorException { } // copy constructor public Fraction(Fraction otherFrac) { } // getters public int getNumer() { } public int getDenom() { } // standard methods public String toString() { } public boolean equals(Fraction rFrac) { } // fraction operators public Fraction add(Fraction rFrac) { } public Fraction sub(Fraction rFrac) { } public Fraction mult(Fraction rFrac) { } public Fraction div(Fraction rFrac) { } public boolean isSimplestForm() { } public Fraction reduce() { } public boolean properFrac() { } public Fraction abs() { } public boolean lessThan(Fraction rFrac) { } public boolean greaterThan(Fraction rFrac) { } public double convertToDecimal() { } public Fraction invert() { } } Note that objects of type Fraction are immutable. Also, the alternate constructor throws an InvalidDenominatorException if passed a denominator value of 0. This exception type is not predefined in Java, so you must define it as follow as another class in your Java project files: public class InvalidDenominatorException extends RuntimeException { } // nothing to implement This creates an exception of type RuntimeException. RuntimeExceptions do not need to be caught when thrown. However, your test driver should have the code for catching this exception where appropriate. For example, if your test driver excutes the following, Fraction frac1 = new Fraction(1,2); then there is no need to catch the possible exception, since it is clear that the denominator is not 0. However, if the value are input by the user, then there is a chance that a denominator vaue of 0 could be entered, and therefore the code for catching the possible exception is needed, int numer, denom; Fraction frac1; Scanner input = new Scanner(System.in); Boolean valid_input = false; while (!valid_input) try { System.out.print(“Enter numerator denominator: “); numer = input.nextInt(); denom = input.nextInt(); frac1 = new Fraction(numer,denom); valid_input = true; } catch (InvalidDenominatorException e) { System.out.println(“Denominator of Zero found – Please reenter”); } catch (InputMismatchException e) { System.out.println(“Non-digit character found – Please reenter”); } etc. Considerations Makes sure the equals method returns true for any two fractions that are arithmetically equal. Make sure that the equals, lessThan and greaterThan methods do not alter the values of the fractions being compared. You may consider the use of private methods .

Note: I only need the last 3 sub-questions ( e, f and g) 3. Firewall Design (55pts) Design a firewall for your Linux machine using the iptables packet filtering mod- It is likely that iptables came pre-installed with the Linux distribution you are using. In the event you are using an old version of the Linux kernel, you may need to upgrade it for iptables to work. Your homework consists of writing iptables rules to do the following: (a) Place no restriction on outbound packets. (b) Allow for ssH access (port 22) to your machine from only the fiu.edu domain. (c) Assuming you are running an HTTPD server on your machine that can make available your entire horne directory to the outside world, write a rule that allows only a single IP address in the internet to access your machine for the HTTP service. (d) Permit Auth/Ident (port 113) that is used by some services like SMTP and (e) Aocept the ICMP Echo requests (as used by ping) ooming from the outside. Respond back with TcP RST or ICMP unreachable for incoming requests blocked ports. (g) Block all input packats from the enn.com domain and respond back with destination unreachable error message for all incoming SYN packets from the cnn.com domain. Solution (e) Echo Request: Ping operates by sending Internet Control Message Protocol (ICMP) echo request packets to the target host and waiting for an ICMP echo reply. It measures the round-trip time from transmission to reception, reporting errors and packet loss. Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network. Packet InterNet Gopher, is a computer network administration utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the total round-trip time for messages sent from the originating host to a destination computer and back. Ping operates by sending Internet Control Message Protocol (ICMP) Echo Request packets to the target host and waiting for an ICMP Echo Reply. The program reports errors, packet loss, and a statistical summary of the results, typically including the minimum, maximum, the mean round- trip times, and standard deviation of the mean. The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol suite. It is used by network devices, like routers, to send error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached. ICMP differs from transport protocols such as TCPand UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end- user network applications (with the exception of some diagnostic tools like ping and traceroute). The Internet Control Message Protocol (ICMP) has many messages that are identified by a “type” field. You need to use 0 and 8 ICMP code types. => Zero (0) is for echo-reply => Eight (8) is for echo-request. To .
