Infrared thermography has evolved into one of the most valuable diagnostic tools for Predictive Maintenance of electrical equipment from reliability and safety point of view.

By detecting anomalies often invisible to the naked eye, thermography allows corrective action to be taken before costly system failures occur or where safety of man and machine are at stake. By utilizing thermography to inspect electrical systems and components under load, the faulty components can be identified and thus heavy loss of health and wealth is avoided.

“Design and Development of 89C51 Microcontroller Based Infrared Remote Control system for Audio Amplifier”
Introduction
 It consist of two sections:the receiving section and the transmitting section.
 The receiving section consists of an Infrared remote.
 In this project I’m using a Sony Infrared remote.
 Whenever a key is pressed on the remote a coded pulse train is emitted. The pattern of the pulse train depends on the key pressed.

Different types of Non-Destructive tests (NDT) are there to detect voids and cracks in concrete such as Ultrasonic Pulse Echo, Ultrasonic Pulse Velocity, Ground Penetrating Radar, Impact Echo Method, X-ray Scanning Method, Rebound Hammer Method, Infrared Thermography Method .In which Infrared Thermography method is discussed in this paper
As concrete is used in newer areas and evidence is coming to light of premature deterioration in concrete structures there is a need to develop new methods for quality control at the time of concrete construc ....etc

Abstract— Computational Private Information Retrieval (cPIR) protocols allow a client to retrieve one bit from a database, without the server inferring any information about the queried bit. These protocols are too costly in practice because they invoke complex arithmetic operations for every bit of the database. In this paper, we present pCloud, a distributed system that constitutes the first attempt toward practical cPIR. Our approach assumes a disk-based architecture that retrieves one page with a single query. Using a striping technique, ....etc
