Building a System

Why is it important to use systems  analysis and design methodologies when building a system?

Why not just build the system in whatever way seems to be “quick and easy”?

 What value is provided by  using an “engineering” approach?

Also, Give a specific example of an  organization (not one listed in the book) that does a good job of this and why.

human dependence

·         One – Are alternative energy sources the answer to ending human dependence on oil?

·         Two –Is global warming due to human actions? Can the human race take action to stop global warming?

·         Three – Is genetic engineering the answer

Quantum mechanics

quantum mechanics

Important Guidelines:

· Show all the major solution steps

· Always end your answers with the proper units 

Solve and submit the following problems:

4. (I) If an electron’s position can be measured to an accuracy of 2.0 x how accurately can its speed be known?

6. (I) The boson, discovered in 1985, is the mediator of the weak nuclear force, and it typically decays very quickly. Its average rest energy is 91.19 GeV, but its short lifetime shows up as an intrinsic width of 2.5 GeV (rest energy uncertainty). What is the lifetime of this particle?

8. (II) A free neutron (m = 1.67 x kg) has a mean life of 900 s. What is the uncertainty in its mass (in kg)? 

14. (I) For n = 5, I = 3, what are the possible values of and  and  ? 

18. (I) List the quantum numbers for each electron in the ground state of nitrogen (Z = 7) 

20. (I) Calculate the magnitude of the angular momentum of an electron in the n = 4, I = 3 state of hydrogen.

Technical Term Project Paper

Assignment 5: Technical Term Project Paper You are a small project management  consulting company called Big-Proj that is looking for that big break. You are  one of ten (1 of 10) project managers in your organization. Recently, you made a  persuasive and high-level presentation of your company’s approach to managing  projects on time and on schedule in accordance with the PMBOK®. Leads are  pouring in. It looks like business is about to pick up. Your small but  experienced team of ten (10) PMP-certified project managers have managed a wide  range of small capital projects, namely wiring closets, wireless, data center  moves, network upgrades, and ERP deployments. You have been selected to  initiate, plan, execute, monitor, and control and close a data center move in a  30-day period. Overview Fiction Corporation is a large national retail  chain of 10,000 employees and 500 retail outlets. Fiction is moving its primary  data center operation to a new headquarters building several miles away. The  company wishes to upgrade its network and correct any security flaws in its  infrastructure as part of this move. The Fiction CEO has informed you that the  capital budget cannot exceed $500,000 and must not interrupt business  operations. What follows is a brief overview that will serve as your foundation  in developing the network design. The data in the center supports remote  retail locations, an off-site 100-seat call center and 3 remote warehousing  operations 24 hours a day. Any significant downtime to its production systems  would impact Fiction Corporation’s operations and profitability. From the data  processing viewpoint, the move includes 2 large UPS, 4 RS/6000 AIX application  servers, 10 virtualized servers, and 20 PC servers. The network consists of  approximately 500 remote location retail stores connected via frame relay (with  ISDN backup) to 10 routers at the data center running a common LAN shared by the  entire organization. The retail operations also run WLANs that are on their own  subnet. You will have a T1 link and ISDN as its backup. Network managers also  need to monitor the status of remote systems. The SNMP management system must be  able to detect and report failure of the remote system or its communications  link and the status of individual applications. The company wishes a seamless  migration that minimizes impact to its customers and employees. Any gaps in  this background will require you to make sound technical and persuasive  assumptions that satisfy the customer’s goals that are within the budget  guidelines. You were selected in part due to your detailed analysis and  agreement to an implementation cost that will not exceed $500,000. Your network  migration plan will be in accordance to the PMBOK® process areas and will use  standard project management software to manage the budget and associated tasks.  Key to the success of this plan is adherence to the scope, time, and cost  baseline. Technically, the client must ensure the availability of a T1 link  between the remote sites to support remote bridging and development of  configurations for all the remote routers. Students may have to create  fictitious assumptions and details in support of this assignment. Write a ten  to fifteen (10-15) page paper that addresses the following: 1. Describe how  you would initiate the project. 2. Create a project plan for moving the data  center, considering the budget and time constraints. 3. Develop an inclusive  plan that incorporates the five (5) process areas and nine (9) knowledge areas  of the PMBOK®. 4. Create the project work breakdown structure and resource  sheet in Microsoft Project or its open source alternative. 5. Describe how  you will monitor and control the plan. 6. Explain the methods you would use  to close the project.
