1. INTRODUCTION 1. OVERVIEW In order to achieve several small scale and large scale objectives in various electronic circuits‚ it is highly essential to regulate the voltage supply‚ given to electronic circuits. This project‚ namely VARIABLE VOLTAGE REGULATOR‚ aims at fulfilling such small goals‚ using the 3-terminal voltage regulator LM317. The circuit consists of an IC LM317 and a set of resistors and capacitors‚ in addition to the transformer and the rectifying element. The AC

Fad: The Fading Correlation Between Fashion and Social Class Change is inevitable‚ as Charles Darwin has proven through his theory of evolution. Starting from as early as the 13th century to the present day‚ fashion and its role in society has significantly evolved. The evidence of this evolution shows exactly how the connection between fashion and social status within different societies has changed over time. Fashion is a very popular part of any culture‚ with a variety of different colors‚ fabrics

However‚ only when the sample is large can we meaningfully divide the data into 100 groups( percentiles).

If an otherwise excellent experiment is summarized by a weak conclusion‚ the results will not be taken seriously. Success or failure

Absorption and Variable Costing‚ Inventory Management Absorption and Variable costing are very important tools for cost accounting. Both of these costing methods allow you to see the cost of your inventory‚ in a different way. For example the absorption method allows you to assign all costs to the product‚ while variable costing allows only variable costs to be assigned to the product. Inventory management is extremely important as well because it ties into efficiency and lowering your costs

Technology is in every part of our lives and everyday items have a great number of variable social‚ economic‚ cultural and symbolic meanings to different individuals. In our discussion group we see how simple everyday items such as cups‚ purses‚ pop cans‚ keys‚ cell phones and other items evoke different associations and meanings for individuals. There are a wide variety of other items that were also discussed and students shared their perspective about the meanings of these items as well. A summary

Correlation is a statistical technique used by statistics experts and researchers to determine if and to what extent are two variables related in a research. For instance‚ being in a relationship is correlated to being married. In this care correlation technique will determine if indeed being in a relationship has any relationship to being married. In this case it will also determine how likely or unlikely a person in a relationship will marry. Covariance on the other hand measures to what extent

What is learning style:- The various preferences and methods employed by learners in the process of learning. Every individual have different style and techniques of learning. Some people may find that they have a dominant style of learning‚ with far less use of the other styles. Others may find that they use different styles in different circumstances. There is no right mix. Nor are your styles fixed. You can develop ability in less dominant styles‚ as well as further develop styles that you

Types of Variables Binary variable Obsevations (i.e.‚ dependent variables) that occur in one of two possible states‚ often labelled zero and one. E.g.‚ “improved/not improved” and “completed task/failed to complete task.” Usually an independent or predictor variable that contains values indicating membership in one of several possible categories. E.g.‚ gender (male or female)‚ marital status (married‚ single‚ divorced‚ widowed). The categories are often assigned numerical values used as lables
