As many of the industries use induction motors. So, controlling of induction motor plays a very vital role. So,
our project concentrates on controlling the speed of induction motor using Android phone remotely by the help of the
Bluetooth technology. We use Android application which uses Bluetooth to connect to the Bluetooth modem of
control circuit which is connected to the motor. Bluetooth modem is interfaced with microcontroller. The Bluetooth
slave modem receives the command from the mobile phone. The Bluetooth modem sends the signal to the
Microcontroller. The Microcontroller decodes the signal and sends to the relays. Then, respective relay operates to
change the speed of Induction motor from 0% to 100%.
We are not only controlling the speed of the Induction motor, using feedback network we can also detect the
over temperature, high voltage, low voltage, MCB tripping on account of any faults. And we are also adding an extra
application which is very important in industries. That is, monitoring of phase lines. Because these types of
uncertainties like over temperature, high voltage, low voltage etc are likely to happen in Industries. So, this project
will be very helpful in industries, house hold, shopping malls etc.Development of Software for Estimation of Structural Dynamic Characteristics ...
This document describes the development of software to estimate the structural dynamic characteristics of mechanical systems in real time. The software uses LabVIEW to analyze data from sensors measuring the response of a mechanical beam to applied forces. Signal processing methods extract parameters like resonance frequencies and damping from the sensor data. The software is also designed to provide closed-loop control to achieve a desired acceleration level at a specified point on the structure. This allows testing structural vibration within set parameters in the laboratory prior to flight.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
