Design of a GSM Cell – Phone based Vehicle Monitoring & Theft Security System

This project will focus on developing an enhancement of the vehicle alarm security system via SMS. The system will manipulate a mobile phone to send SMS (Short Message Service). Even though the SMS can be sent using the features available in the mobile, the objective of this project is to activate the SMS sending by the mobile phone using external program, connected physically to the mobile phone. The study of telecommunication is an interesting field because it involves digital signal processing, signal and systems, programming and more. This inspires people to improvise the technology into daily use. In this project, the technology of telecommunication, to be specific; SMS, is integrated or improvised to the present vehicle security system. Instead of human to human telecommunication, this system creates new entity which is machine to human telecommunication. This system is an upgrading and improving vehicle security system by integrating SMS features to alert vehicle owners whenever intrusion occurs. This project involves hardware and software parts construction and the integration of both parts to create the system. We succeed in achieving the objective and in fact, add another feature to the system which will initiates a call to the owner after sending the SMS. In the end of this project, we will document all the hardware and software development and provide a simulation model of the system. An interfacing mobile is also connected to the microcontroller, which is in turn, connected to the engine. Once, the vehicle is being stolen, the information is being used by the vehicle owner for further processing. The information is passed onto the central processing insurance system which is in the form of the sms, the microcontroller unit reads the sms and sends it to the Global Positioning System (GPS) module and using the triangulation method, GPS module feeds the exact location in the form of latitude and longitude to the user’s mobile. By reading the signals received by the mobile, one can control the ignition of the engine

Synthesis, characterization, electrochemical and catalytic performance of NiO nanostructures and Ag-NiO nanocomposite

Nanocomposites comprising oxide and metal nanoparticles could significantly boost respective functionalities attributing to their synergistic properties. Present work reports synthesis of NiO and its composite; Ag-NiO nanocomposite. The study highlights electrochemical and catalytic performances of synthesized materials. The X-ray diffraction pattern, X-ray photoelectron spectra, magnetic and morphological study is presented with detailed analysis. Transmission electron microscopy images showed Ag nanoparticles distributed within NiO nanostructures. The cyclic voltammetry results showed specific capacitance of 231 F/g for Ag-NiO nanocomposite; higher than bare NiO (90 F/g) at 5 mV/s scan rate in 1 M KOH electrolyte. Moreover, the Ag-NiO nanocomposite exhibited significant catalytic activity towards methylene blue reduction with rate constant 1.1 × 10−2 s−1. The study covers basic analysis of NiO and Ag-NiO nanocomposite extending towards their functional performance
