CHAPTER I 1.1 Introduction: These days‚ hot products like mobile phones‚ GPS and computers can be secured at the touch of a fingerprint. Designing in security at the start of a new product development process is more effective than adding it on later. Unlocking your mobile phone by scanning your fingerprint is not a thing of science fiction. It’s an everyday reality for millions of mobile phone users‚ the greatest proportion of who live in Asia. But designing-in security to mobile phones can be

Friction is the force resisting the relative motion of solid surfaces‚ fluid layers‚ and material elements sliding against each other. There are several types of friction: Dry friction resists relative lateral motion of two solid surfaces in contact. Dry friction is subdivided into static friction ("stiction") between non-moving surfaces‚ and kinetic friction between moving surfaces. Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other.[1][2]

These false images can either be externally imposed or internally fabricated. In either case‚ one must have the courage to look through this ignorance so that ones true self can be exposed. After reading Mirrors it was obvious that‚ Lucy Grealy cared what others thought about her physical appearance. In time‚ however

Fingerprint Removal Essay Fingerprints have been used for centuries to help put criminals behind bars and the innocent out of jail‚ but some fugitives believe they can alter themselves to have no fingerprints and therefore have no way of being traced. However‚ fingerprints are not easy to get rid of‚ but that does not stop those crazy enough to try. John Dillinger‚ a notorious escape artist and bank robber‚ was on the verge of getting permanently locked away. He believed his only chance of not

Fingerprint Debate The value of fingerprinting and background checks is to make sure that the students are being protected. It is extremely important that for the safety of the students as well as the other teachers the school must do thorough background and fingerprinting checks. In doing background and fingerprinting checks you can tell the employer with pieces of information about the teachers background’s that can share credit reports‚ social Security number‚ criminal records

experiment is to study the friction loss along a pipe. In this experiment‚ water and mercury have been used to demonstrate the law of resistance with different types of flow which are laminar and turbulent flow. The variation of head loss will be obtained and hence determined the Reynold numbers and friction factor. In the end of the experiment‚ the law of resistance which is the relationship between i and u will be determined and hence established the critical R and friction factor. 1.0 Introduction

Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

Introduction The purpose of this lab is to determine: the coefficient of friction between a rubber stopper and a wooden ramp the coefficient of static friction between a wooden block and a wooden ramp the coefficient of kinetic friction between a wooden block and a wooden ramp The design of this experiment was done by placing a rubber stopper / wooden block onto a wooden ramp and tilting the ramp at a certain degree to cause the stopper / block to move. The measurements of the vertical distance

you didn’t do is not only unfair‚ but also injustice. Although fingerprints are crucial evidence and data of a case‚ it’s not the only piece of information available. While trying someone for a case‚ it’s only lawful if the jurors understand the process and basic principles of the technique. However‚ the system of unskilled jurors can be improved. These days‚ fingerprinting people seems pretty cunning. With a DNA database‚ fingerprints seem like a reliable source. For example‚ if a homicide were to
