Short note on Uniform Gradient Cash Flow and PERT

-

 Uniform Gradient Cash Flow

If the cash flow has the proper form its present worth can be determined by using the uniform gradient factor(P=G(P/G, i, n). The uniform gradient factor finds the present worth a uniformly increasing cash flow. For example, if the cash flow in period 1 is 2000 and in period 2 is 2100. it would be uniform if the subsequent amounts increased by 100 in each subsequent period. This gradient in this example would be equal to 100.


PERT

A PERT chart is a project management tool that provides a graphical representation of a project's timeline. The Program Evaluation Review Technique (PERT) breaks down the individual tasks of a project for analysis. PERT charts are considered preferable to Gantt charts in some cases because they identify task dependencies, but they're often more difficult to interpret.

A PERT chart allows managers to evaluate the time and resources necessary to manage a project. the Project Evaluation Review Technique, or PERT, is used to identify the time it takes to finish a particular task or activity. It is a system that helps in the proper scheduling and coordination of all tasks throughout a project. It also helps in keeping track of the progress, or lack thereof, of the overall project. In the 1950s, the Project Evaluation Review Technique was developed by the US Navy to manage the Polaris submarine missile program of their Special Projects Office.A PERT chart uses circles or rectangles called nodes to represent project events or milestones. These nodes are linked by vectors, or lines, that represent various tasks.

Advantages of PERT

Here are several benefits of using PERT in project management:

  • It helps maximize the use of resources.
  • It makes project planning more manageable.
  • It’s useful even if there is little or no previous schedule data.
  • It enables project managers to better estimate or determines a more definite completion date.

Disadvantages of PERT

Like any other method, PERT comes with its share of limitations:

  • In complex projects, many find PERT hard to interpret, so they may also use a Gantt Chart, another popular method for project management.
  • It can be tedious to update, modify, and maintain the PERT diagram.
  • It entails a subjective time analysis of activities and, for those who are less experienced or are biased, this may affect the project’s schedule.

Suppose that a data warehouse for Big-University consists of the following four dimensions: student, course, semester, and instructor, and two measures count and avg_grade. When at the lowest conceptual level (e.g., for a given student, course, semester, and instructor combination), the avg_grade measure stores the actual course grade of the student. At higher conceptual levels, avg_grade stores the average grade for the given combination. a) Draw a snowflake schema diagram for the data warehouse. b) Starting with the base cuboid [student, course, semester, instructor], what specific OLAP operations (e.g., roll-up from semester to year) should one perform in order to list the average grade of CS courses for each BigUniversity student. c) If each dimension has five levels (including all), such as “student < major < status < university < all”, how many cuboids will this cube contain (including the base and apex cuboids)?

a) A Snowflake Shema is shown in figure below: b) The specific OLAP operations to be performed: 1. Roll-up on course from course_id to department. 2. Roll-up on a student from student_id to university. 3. Dice on course, student with department ="CS" and university = "biguniversity" 4. Drill-down on a student from the university to student_name. c) N = 4 dimensions The cube will contain 54 = 625 cuboids.

Suppose that a data warehouse consists of the four dimensions; date, spectator, location, and game, and the two measures, count and charge, where charge is the fee that a spectator pays when watching a game on a given date. Spectators may be students, adults, or seniors, with each category having its own charge rate. a) Draw a star schema diagram for the data b) Starting with the base cuboid [date; spectator; location; game], what specific OLAP operations should perform in order to list the total charge paid by student spectators at GM Place in 2004?

Discuss classification or taxonomy of virtualization at different levels.

Taxonomy of virtualization Virtualization is mainly used to emulate the execution environment, storage, and networks. The execution environment is classified into two: – Process-level – implemented on top of an existing operating system.  – System-level – implemented directly on hardware and does not or minimum requirement of the existing operating system. OR,  Virtualization covers a wide range of emulation techniques that are applied to different areas of computing. A classification of these techniques helps us better understand their characteristics and use  V irtualization is mainly used to emulate  ● Execution Environments: To provide support for the execution of the programs eg. OS, and Application.  ○ Process Level: Implemented on top of an existing OS that has full control of the hardware  ○ System Level: Implemented directly on Hardware and do not require support from existing OS.  ● Storage: Storage vi...
