Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

Simple Harmonic Motion Objective The purpose of this experiment was to investigate the different variables describing simple harmonic motion (SHM) using a spring-mass system in vertical oscillation. We measured the position and velocity of the spring-mass system under different conditions in order to extract parameters used to describe SHM such as amplitude‚ frequency‚ and phase. We tested whether the predicted behaviour based on our mathematical model of SHM was cohesive with the observed parameters

technique of video image processing used to solve problems associated with the real-time road traffic control systems. There is a growing demand for road traffic data of all kinds. Increasing congestion problems and problems associated with existing detectors spawned an interest in such new vehicle detection technologies. But the systems have difficulties with congestion‚ shadows and lighting transitions. Problem concerning any practical image processing application to road traffic

USA Received 1 July 2002; accepted 21 May 2003 Abstract The most frequently used inspection methods‚ i.e.‚ visual examination‚ dye penetrant examination‚ magnetic particle examination‚ eddy current examination‚ and ultrasonic examination‚ are‚ for the most part‚ effective and reliable. There have been instances‚ however‚ particularly in the aviation field‚ where the designated methods of inspection were not able to detect cracks‚ and as a result catastrophic failures occurred

Types of Information Security Controls Harold F. Tipton Security is generally defined as the freedom from danger or as the condition of safety. Computer security‚ specifically‚ is the protection of data in a system against unauthorized disclosure‚ modification‚ or destruction and protection of the computer system itself against unauthorized use‚ modification‚ or denial of service. Because certain computer security controls inhibit productivity‚ security is typically a compromise toward which security
