CHAPTER 1: INTRODUCTION
Here is an inexpensive auto cut-off circuit, which is fabricated using transistor and other discrete components. It can be used to protect loads such as refrigerator, T.V., and VCR from undesirable over and under line voltages, as well as surges caused due to sudden failure/resumption of main power supply. This circuit can be used directly as a standalone circuit between the mains supply and the load, or it may be inserted between an existing automatic/manual stabilizer and the load.
The over/u ....etc

Green House technique can increase cultivation output if a proper potion of agro-tech can be administered such as...the use of polytunnel(lost cost alternative to glass green house making it possible to grow even Mediterranean crops in India+exotic ,off seasonal vegetables for food industry), LED lighting for faster crop growth, climate control system driven by solar and wind hybrid power and use of organic/ household manure. With unsatisfactory cultivation in India adding to the woes of the farmers this project holds great promise and it could ....etc

Pile driving at large construction sites produces formidable noise. Marine pile driving similarly can produce high sound pressures underwater”but these can be lethal to fish and can harass marine mammals, including those protected by federal law. This problem has contributed to costly construction delays on major bridge projects. To protect marine life, engineers have designed air bubble curtains to reduce underwater sounds. Air provides an effective barrier to sound propagating through water, because of the difference in density betwee ....etc

Vertical Take “ off and Landing
INTRODUCTION
Twenty years after ever jet flight took place, vertical takeoff and landing (VTOL) emerged as a concept, which was soon to be successfully implemented. Dr A.A Griffith, in 1941 who was then the chief engineer of Rolls Royce ltd. put forward this idea in his paper to the aeronautical research council. He proposed the idea of using small lift engines for lift only and not for normal flight. He claimed that there was great advantage in using a wing configuration and prop ....etc

The recognition of off-line unconstrained handwriting is one of the most challenging and interesting problems in Optical Character Recognition (OCR). Although many research have been done in this field for about 40 years, a number of problems are still open to us. In this seminars, an integrated recognition system for off-line unconstrained handwriting is proposed. The proposed system consists of seven main modules: skew angle correction, printed-handwritten text discrimination, line segmentation, slant correction, word segmentation, character ....etc

AUTOMATIC SPEED CONTROLLER FOR FANS WITH ON/OFF CONTROL BY LIGHT

ABSTRACT
The circuit designed here lets us turn ON/OFF a fan or any device by just directing a torch light or any other light towards its light-dependent resistor. In short we are tiying to develop a remote control for turning ON/OFF an electronic device.
During summer nights, the temperature is initially quite high. As time passes, the temperature starts dropping. Also, after a person falls asleep, the metabolic rate of one's body decreases. Thus, init ....etc
