  5. In image processing and pattern recognition how you can determine a square block in an image? Explain.                                                                                         5
Section D
  1. Technical Writing                                                                                              10
      1. Let you are an IT Officer in IT Department of your organization and IT Department has much more computers in the store to be distributed to all units. One of your organization's unit requested your department to provide three computers to computerize their official activities and data.Your in-charge commanded you to visit the site and prepare a report addressing the following points given below:
          1. a.What is the current IT infrastructure in the unit?
          2. b.Status of man power dedicated in the IT field.
          3. How they are using the computers?

                            Prepare a report as addressed above.Let you think that it would be better to provide three computers to the unit.Describe what will be the effect after providing three computers to it.Give reasonable cause in the report for providing the computers to the unit.

       2. Case Study:                                                                                             (10+10=20)
                          Ministry of Health and Population is willing to computerize its data basic.       This new system will be able to tell the population of the country,zone and district and even of the ward of a specific place.The system will update is data in monthly basis so that the birth rate and death rate can be easily be seen.
                          a). Now as an computer engineering,draw a context and data flow diagram                                 for the possible system.
                          b). Design the efficient database schema for the proposed system will                                         appropriate normalization methods.
