## Optical Mark Recognition using MATLAB

Optical Marking Recognition (OMR) Optical Marking Recognition using MATLAB Software is for marking tests or extract data from documents such as survey. This software obtained marked data from specific sheet designed for this, called as OMR sheet. Basically, this recognition software falls in category of image processing.  We are going to write our own code […]

## Turns per Volts Derivation Transformer Design

Derivation of Formula for Calculation of Turns per Volts of Transformer Design For designing a transformer, we need certain number of turns on each side for a specific rating transformer. Voltages on each side have direct relation with number of turns. So, we are interested in finding  voltage per turn and for designing, turns per voltage. […]

## Cruise Control using Fuzzy MATLAB tool

Fuzzy Logic:           Designing a controller for non-linear systems is difficult. For conventional controller design we require mathematical  model and higher order differential equations. Some times we linearize mathematical model and design controller for system by applying well developed techniques for solving linear equations. But, as we know that real life […]

## Basics of Some Solid State Switches

Switches are devices which allows the current in one direction and blocks the current in other. Solid state switches are devices made up of semi conducting elements with doping in them. Power electronics and most of the devices around us made up of these switching elements. They found application in every circuit of power electronics. […]
