IOT based Smart Unlawful Electricity Usage Surveillance and Warning System

The global issue of electricity theft has a negative impact on both the utilities and the people who use the energy. It impairs utility company economic growth, creates electrical risks, and has an effect on consumers' expenses for electricity. The emergence of smart grids is crucial for the detection of power theft as they provide vast amounts of data, including information on consumer consumption that can be used to identify theft using over voltage and over current detection methods. The solution presented in this article employs an Arduino uno micro controller board and IOT to monitor and maintain surveillance on power theft. An alarm with SMS notification will be sent to the officials and the power will be shut off whenever there is a power outage or tampering with an energy meter

Gravitation search algorithm: Application to the optimal IIR filter design

This paper presents a global heuristic search optimization technique known as Gravitation Search Algorithm (GSA) for the design of 8th order Infinite Impulse Response (IIR), low pass (LP), high pass (HP), band pass (BP) and band stop (BS) filters considering various non-linear characteristics of the filter design problems. This paper also adopts a novel fitness function in order to improve the stop band attenuation to a great extent. In GSA, law of gravity and mass interactions among different particles are adopted for handling the non-linear IIR filter design optimization problem. In this optimization technique, searcher agents are the collection of masses and interactions among them are governed by the Newtonian gravity and the laws of motion. The performances of the GSA based IIR filter designs have proven to be superior as compared to those obtained by real coded genetic algorithm (RGA) and standard Particle Swarm Optimization (PSO). Extensive simulation results affirm that the proposed approach using GSA outperforms over its counterparts not only in terms of quality output, i.e., sharpness at cut-off, smaller pass band ripple, higher stop band attenuation, but also the fastest convergence speed with assured stability

Design and Practical Application of a Cost Effective Intelligent Female Surveillance System Using GPS, GSM, and Arduino Technology

This paper suggests a cost effective, portable and intelligent surveillance system for women that they can utilize in risky or emergency situations. In this design, an Arduino Nano microcontroller, a GPS module, and a GSM module are the main parts used. Whenever an emergency arises, the user can instantly send an emergency message to a preset phone number along with their current location. The emergency activation button is in a handy place on the gadget, which is tiny enough to carry in a pocket or purse. This device will improve women's protection and security, particularly in places with high crime rates or poor public safety
