Chapter 19, Problem 19.4E
Explanation of Solution
Wicked Problem of Medical records:
A wicked problem is a problem that is so complex and which involves so many related entities that there is no definitive problem specification.
- Different stakeholders see the problem in different ways and no one has a full understanding of the problem as a whole.
- A wicked problem does not have any definite problem specification.
- The specifications are mostly changing, incomplete and hard to recognize and contradictory.
- A wicked problem cannot be solved with a linear approach and hence it is difficult to solve a wicked problem.
The development of a national medical records system is a wicked problem because of the following reasons:
- Patient records are maintained in their own way by different medical specialties and institutions according to how they use these records. In a national system, there is no general agreement on what information must be maintained and the way in which that information is presented...

In the GoF book, List interface is defined as follows:
interface List {
int count(); //return the current number of elements in the list
Object get(int index); //return the object at the index in the list
Object first(); //return the first object in the list
Object last(); //return the last object in the list
boolean include(Object obj); //return true is the object in the list
void append(Object obj); //append the object to the end of the list
void prepend(Object obj); //insert the object to the front of the list
void delete(Object obj); //remove the object from the list
void deleteLast(); //remove the last element of the list
void deleteFirst(); //remove the first element of the list
void deleteAll(); //remove all elements of the list
(a) Write a class adapter to adapt Java ArrayList to GoF List interface.
(b) Write a main program to test your adapters through List interface.
(c) Same requirement as (a) and (b), but write an object adapter to adapt Java ArrayList to GoF

In modern packet-switched networks, including the Internet, the source host segments long, application-layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 (attached) illustrates the end-to-end transport of a message with and without message segmentation. Consider a message that is 106 bits long that is to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 5 Mbps. Ignore propagation, queuing, and processing delays.
a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host?
b. Now…
Consider a packet of length L that begins at end system A and travels over three links to a destination end system. These three links are connected by two packet switches. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1, 2, 3. The packet switch delays each packet by dproc. Assuming no queuing delays, in terms of di, si, Ri, (i = 1, 2, 3), and L, what is the total end-to-end delay for the packet? Suppose now the packet is 1,500 bytes, the propagation speed on all three links is 2.5 * 10^8 m/s, the transmission rates of all three links are 2.5 Mbps, the packet switch processing delay is 3 msec, the length of the first link is 5,000 km, the length of the second link is 4,000 km, and the length of the last link is 1,000 km. For these values, what is the end-to-end delay?
