Displacement value in suppositories

by

The Fundamental Problem: Density Mismatch Imagine a suppository mould is like a fixed-volume ice cube tray. When you pour water in, each “cube” holds exactly 1 gram. The mould is calibrated for a specific volume. Now, the suppository base (e.g., cocoa butter) has a known density. The manufacturer calibrates the mould so that when you use pure base, the resulting suppository … Read more

Input and Output Design

by

The input design is the link between the information system and the user. It comprises the developing specification and procedures for data preparation and those steps are necessary to put transaction data in to a usable form for processing can be achieved by inspecting the computer to read data from a written or printed document or it can occur by having people keying the data directly into the system.

A quality output is one, which meets the requirements of the end user and presents the information clearly. In any system results of processing are communicated to the users and to other system through outputs. In output design it is determined how the information is to be displaced for immediate need and also the hard copy output.

Number System

by

When we type some letters or words, the computer translates them in numbers as computers can understand only numbers. A computer can understand the positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number.

The value of each digit in a number can be determined using −

  • The digit
  • The position of the digit in the number
  • The base of the number system (where the base is defined as the total number of digits available in the number system)

Feasibility Studies

by

As the name implies, a feasibility study is an analysis of the viability of an idea. The feasibility study focuses on helping answer the essential question of “should we proceed with the proposed project idea?” All activities of the study are directed toward helping answer this question.
