Question

In this Application, create a structural model that depicts the system’s interactions with the students in the WestEast College case. Perform the following steps:

• Identify the classes implied by the case.
• For each class, create a CRC card that includes appropriate attributes such as the student’s ID number, name, address, and phone number.
• Explain and justify your choices.
• Briefly explain the relationship between your structural model and your functional model.

WestEast College Case

WestEast College hires you as a systems analyst to design its new admission/registration system.

WestEast College is one of the top ranked schools in the United States. It is a small private college with nearly 3,000 students, 100 faculty, and 50 supporting staff (including 10 full-time and four part-time IT staff who are responsible for supporting all academic and operational IT needs).

The college accepts new and transfer students from other colleges and countries. The college only accepts online applications.

Once prospective students have completed and submitted their application and the college receives it, they submit additional documentation such as transcripts, recommendation letters, a personal essay, residency information, proof of language proficiency, and financial aid documents.

Once students are accepted, they take a placement test for math and English. If students pass the required tests, they are assigned general education classes (such as math, English, and social studies). If they do not pass a subject, they are assigned intensive classes in the failing subject.

Students progress through four years of classes and must maintain a 2.00 GPA or they are placed on probation for 2 quarters. If they drop below 2.00, students are dismissed. They must score at least a C to move to the next class or they must repeat the class (a D is not an acceptable grade).

Students must finish their degrees in no more than 5 years and cannot switch majors more than twice.

Students eligible for graduation must pass an assessment test in their major before they may graduate.

Answer 1

We investigated the relationship between structural network properties and both synchronization strength and functional characteristics in a combined neural mass and graph theoretical model of the electroencephalogram (EEG). Thirty-two neural mass models (NMMs), each representing the lump activity of reasonably large groups of interacting excitatory and inhibitory neurons, were reciprocally and excitatory coupled using random rewiring as described by Watts and Strogatz. Numerical analysis of the network revealed an abrupt transition towards a synchronized state as a function of increasing coupling strength alpha. Synchronization increased with increasing degree and decreasing regularity of the network. Parameters of the functional network showed a diverse dependency on structural connectivity: normalized clustering coefficient gamma and path length lambda increased with increasing alpha. For sufficiently large alpha, however, gamma decreased with increasing rewiring probability p, while lambda increased. Hence, a structured functional network exists despite the randomness of the underlying structural network. That is, patterns of functional connectivity are influenced by patterns of the corresponding structural level but do not necessarily agree with those.
