In this project we propose to measure the glucose level of a person in non-invasive way. Some biological parameters of human body are closely related with glucose levels. Keeping this fact in mind using sensors and machine learning we have developed a sensor based glucose measuring device which will measure body glucose level in non-invasive way. We will use PPG sensor for the purpose of glucose measurement. Our goal is to replace the present invasive-glucose measurement with our designed non-invasive glucose monitoring device. Also our designed device will be low-cost.

The aim of this study is to make an automated exchangeable railway track at junction crossing and centralized monitoring system to detect the exact position of the train for safety surveillance as well as efficient railway scheduling and changeable railway routes. The proposed model is based on Arduino microcontroller to reduce complexity and execution cost. Infrared sensors have been employed to track down the position of the moving train. DC motor along with manually-made linear actuator has been used to control the switch gate movement. Total system can be monitored and visualized by a software that shows train position. There is also a scope for statistical data collection and implementation.  This system can work both automatically and manually from the control room. This model works for multi-junction railway tracks and one or more train moving along the track simultaneously.

An autonomous trash collecting robot which moves to search for  trash lying on ground and collects them to the trash-container attached to it can be a solution to the problem. The trash detection is done via deep learning algorithm. An ultrasonic sonar sensor on the robot detects object along the path and with camera module obtains pictures of the object.Via deep learning technics object is classified into trash or not trash. The prototype robot is of lowcost and can detect a wide range of trash with high accuracy therefore has good environmental as well as economic impact.

In this project a copy-move image forgery detection scheme is developed based on a block matching algorithm. 2D-DWT is performed on the forged image and then DWT domain blocks are considered, where only approximate DWT coefficients are utilized. In order to reduce the computational burden, unlike conventional approaches, instead of performing block matching operation among all blocks, some candidate blocks are first selected from the non-overlapping blocks based on a similarity measure. In the next stage, all overlapping blocks are compared with the candidate blocks.

In this project a railway track  changing system was designed .The process was first simulated in proteus software and later was it was implemented in hardware.

In this project a switch code lock circuit has been implemented which can operate without any programming. This circuit is simple and made up of simple magnetic relay and switch. The main principle of this circuit is that the final appliance (which can be a door lock, or a simple motor) works only when all the switches in series are turned on at a time. If any switch which is in parallel is turned on, the appliance is turned off. In real life, these switches can be arranged in any order to turn on the appliance.

In this work layout ,conduit and connection diagram as well as switching diagrams and Distribution board ,Sub distribution board connection diagram , earthing ,wire settings etc. were designed to serve the necessary electrical supply purpose of a two unit six storied buildings as well as corresponding calculations were also performed.

A fire alarm have been developed  which consists of three major parts named rectifying part, amplification part and relay module. The rectification of an AC wave to dc has been done using a bridge rectifier consisting of 4 diodes, a capacitor and a Zener diode. For amplification and temperature detection BJT's have been used which are pretty much sensitive to temperature. The relay module works as a controller of an SPDT switch by presence of flow of current through a coil. If the currents flows in the coil, so will a closed loop appear which will let the current to flow. And this make the alarm to be activated and make people know of the fire which will save their lives. Using PSpice Simulation we can predict the behavior of the circuit which saves our time and cost.
