The title of my PG project which i have done was Performance Evaluation of Solar Still with Inclined Side walls. solar still is a innovative and environmental friendly concept for generating the drinking water from the natural evaporation process. But the drawback of it was the effeciency and ouput was much low when compared with existing methods, so i just inovated the conventional solar still with some changes in design like providing inclination of about 25 degree to the two side walls of the still and tested the performance and i got positive results and the increase in efficiency of about 15% greater than the conventional still and got the increase in productivity of about 20% greater than the conventional still.

Electronic Braking System for Motor Drives is the title of my ug project. which is suitable for the industry where accurate braking of D.C motor at proper position is required even it is fully loaded. The motor braking concept is slightly similar to the dynamic braking, but the dynamic braking is suitable for d.c motor with no load. since if the braking is applied with full load in dynamic braking, then the dynamic resistor will burn out. so instead of resistor, a parallel inverter is coupled in the braking circuit and the output of the parallel inverter is coupled to potential transformer primary side with short-circuited secondary side. hence the accurate and high speed braking is achieved even the motor is fully loaded.

Automatic Black rice remover is the title of my diploma final year project. The project is suitable and related to rice mill industry. colour sensor is used for sensing the rice colour and then the data is feeded to microcontroller then the actuation for removing the odd(Black rice) is removed through pneumatic actuator.
