Abstract

This article aims to reduce power losses and improve system reliability by determining the optimal number, location and size of Photovoltaic Distributed Generators (PV-DG). The PV-DG is modeled as a negative load, draws reactive power from grid and injects real power to the grid. Optimum allocation of PV-DGs and their sizing is obtained by harmony search algorithm (HS) and teaching-learning-based optimization (TLBO) approaches. IEEE 33-bus distribution system was successfully demonstrated by the proposed approach. HS has proven its superiority against TLBO algorithm as it uses less DGs rating devices to enhance distribution system performance. The new contribution in this research is to optimize the number of DGs and does not operate with a given number of DGs (1 DG, 2 DG ,…..) as most of previous works. Another contribution is to study the optimization under several loading conditions.

Abstract

Using the heuristic search approach, this article has attempted a methodology to reduce power (I2R) loss through optimal reconfiguration in the radial distribution system, resulting in a better and optimal design. The suggested approach is verified by testing it on IEEE 33-bus and IEEE 69-bus systems. MATLAB simulation is used to test the proposed solution and the results are presented in this paper.

Abstract

Pressure measurement is critical in many process industries. For commercial purposes, industry uses a variety of pressure sensors for measurement, including sensors based on Micro Electro-Mechanical Systems (MEMS) technology. In this paper, a comparative study with two different Pulse-Width Modulation (PWM) based MEMS pressure sensor has been made. A similar study was made on a sensor with parallel plate mechanical switch and a cantilever based mechanical switch. The result shows that a better mechanical stability can be achieved by the parallel plate structure and better stability is achieved with cantilever structure.

Abstract

This paper presents obstacle detection using image processing and ultrasonic sensor devices. This innovation allows visually handicapped people to navigate confidently and quickly using ultrasonic instrumentation and image processing using Raspberry Pi to detect nearby obstacles and guide them with real-time voice information. This solution makes use of Google Assistant and the Python programming language. The main goal of this project is to assist visually challenged people, and the device can be attached to a hat. This is a simple wearable gadget for the blind.

Abstract

Vehicle accident rates are proportional with the increase in vehicular traffic. Road accidents results in injuries, loss of life and wealth, and in addition, causes lots of personal inconveniences due to the legal proceedings and insurance claim procedures. Most accidents occur due to the human error and non-compliance with traffic rules. The objective of this paper is to propose a technological solution for the implementation of road signs in cases where the driver inadvertently misses these signs. The solution uses RFID technology, thereby alerts the driver and reduces the speed of the vehicle. This project will be useful in sensitive areas such as hospitals, school areas, accident prone areas, etc. where speed limits are enforced. When a vehicle enters a speed limit zone, the vehicle receives an RF signal from a specially programmed RFID tag placed on the lanes, and the vehicle is controlled based on the programmed information. In any worst case scenario the vehicle would be stopped with the help of RFID EM-18 module installed in the vehicle.
