Part (a) The cyclopentadienyl anion (C5H5 - ) is commonly used aromatic ligand. The secular equations for describing the interactions of the five unhybridized p orbitals lead to a matrix of the form:
( ?11 − ??11 ?12 − ??12 ?13 − ??13 ?14 − ??14 ?15 − ??15
?21 − ??21 ?22 − ??22 ?23 − ??23 ?24 − ??24 ?25 − ??25
?31 − ??31 ?32 − ??32 ?33 − ??33 ?34 − ??34 ?35 − ??35
?41 − ??41 ?42 − ??42 ?43 − ??43 ?44 − ??44 ?45 − ??45
?51 − ??51 ?52 − ??42 ?53 − ??53 ?54 − ??54 ?55 − ??55)
where ??? is the Hamiltonian integral for orbitals ? and ? and ??? is the overlap integral for orbitals ? and ?. This matrix can be simplified using the approximations of Hückel molecular orbital (MO) theory, which involves two constants ? and ?.
(i) Explain the approximations of Hückel MO theory in terms of ??? and ???, and define ? and ?.
(ii) Re-write the above matrix applying these assumptions. [You may write this matrix (and only the matrix) on paper and copy and paste and image of it into your word document if you wish.] (iii) Briefly explain (without performing any calculations) how this matrix is used to determine the energies and coefficients of the MOs.

Several issues have arisen on the Recreation and Wellness Intranet Project. The person from the HR department who was supporting the project left the company, and now the team needs more support from that group. A member of the user group that supports the project is extremely vocal and hard to work with, and other users can hardly get a word in at meetings. You are getting weekly status reports from all of the team members, but many of them do not address obvious challenges that people are facing. The team is having difficulty deciding how to communicate various project reports and documents and where to store all of the information being generated. Recall that the team members include you, a programmer/analyst and aspiring project manager; Patrick, a network specialist; Nancy, a business analyst; and Bonnie, another programmer/analyst.
Tasks
1. Summarize three different communications media that could be
used for getting more support from the HR department and which you
think would be most effective.
2. Prepare a sample of a good weekly progress report that could be
used for this project. Include a list of tips to help team members
provide information on these reports.

Read through the Ridgeline Mountain Outfitters (RMO) case study in the text book ( system analysis and design in a changing word). Identify the company's business processes from the key functional areas of their business. DRAW A BUSINESS USE CASE DIAGRAM to show the business processes that take place in the business. The business use case diagram must clearly demonstrate your understanding of their business requirements, and must be sufficient to aid the systems analysts' roles in providing the systems use case diagrams that the designers and developers can use in building the proposed system that can solve the company's overall problems either as a whole or part, in a specified business area. You can provide only one use case diagram where you indicate all the actors and use cases, or you can have multiple diagrams as long as you are able to graphically represent the actors and uses cases and their associations in the business processes that take place in the business. Note that this is a business use case diagram where you have to show your understanding of the business requirements for a proposed business information system for the RMO project.

Step 1: Select any four sorting algorithm and two searching algorithms
Step 2: Understand the logic of all the algorithms
Step 3: Create java program and use your sorting/searching source codes and integrate it into your main java project.
Step 4: Create a separate java class for each algorithm
Step 5: Create a random function that generates at least 100000 random integer numbers from 1 to 1 million(No need to print out or store the numbers)
Step 6: Insert start transaction and end transaction for each sorting and searching methods
Step 7: Calculate the time in milliseconds for each sorting and searching class
Step 8: Compare the performance of each algorithm

Assembly Line Assignment:
This week you are going to design and balance an assembly line. We are going to take the simple task of making cupcakes, break the work up into stations, calculate cycle times for each station, balance the work load between stations, and calculate the efficiency of the operation. The steps for the assignment are below.
1)Design an assembly line to manufacture cupcakes from scratch.
2)Balance the assembly line.
3)Measure the efficiency.
Assignment Format: The best way to do this is Excel. You can use cell borders and insert shapes to build the assembly line. Use the math functions in Excel to balance your line and calculate efficiencies. The final report should be in Word in APA format. Use the following sections.
1)Introduction-how you set up the line, what is done at each station and cycle time. You can cut and paste in your diagram from Excel.
2)Line Balance-what you did to balance the line, you can copy in your Excel work if needed.
3)Efficiency-provide and analyze the operational efficiency.
