Introduction             Electroplating can be defined as the deposition of a metallic coating through the subjection of an object with a negative charge to a solution containing a salt containing positive metal ions. Under the influence of an electric charge, the positive ions are attracted to the negatively charged object where they are reduced hence…

INTRODUCTION – HARMONIC LAOD FLOW ANALYSIS SOFTWARE Power Systems of today are very large, complex interconnected network of various components. Major components of a power system can be subdivided into: a. Generation b. Transmission and Sub transmission c. Distribution Conventional ac electric power systems are designed to operate with sinusoidal voltages and currents. However, nonlinear…

{draw:frame} {draw:frame} I. INTRODUCTION *II. *BASIC CONCEPT OF SVPWM Space Vector Modulation treats the two level inverter of fig. 1 as a single unit which can be driven to eight unique states that each state creates a corresponding voltage vector. An electric-motor control system, comprising: *a two level voltage source inverter. III. *IMPLE*MENTATION OF SPACE…

Secondarily, its thickness allows for wear over the life of the clutch. However, that wear results from a fundamental drawback of diabetics design. Since the armature is thick and massive, it has a high inertia, and all of its originally stationary mass must be “spun up” to match the rapidly rotating pulley and friction disk…

Introduction: The purpose of this article is to criticize Kurt Lewin’s model of change. I will shows how successful change can be encouraged and facilitated for long-term success. The article compares the characteristics of Lewin’s Three-Step Change Theory. According to me Kurt Lewin’s theory is agoal and plan oriented because it only consider about change…

Introduction             In John Mcphee’s book The Control of Nature, he attempts to look into several natural phenomena and how people have attempted to cope with the serious effects brought about by these events. In Atchafalaya, Mcphee notes that attempt of man to “prevent the Mississippi from changing course by controlling flows diverted into the…

Lab #3: Initial Velocity of a Projectile Theory: How can we determine the initial velocity of a projectile? Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics, there are the x…

The purpose of this experiment is to show that the magnitude and direction of the resultant of several forces acting on a particle may be determined by drawing the proper vector diagram and that the particle is in equilibrium when the resultant force is zero. Principles RABx = Ax + Bx RABy = Ay +…

Sir Issac Newton Essay, Research Paper Sir Isaac Newton ( 1642 – 1727 ) Isaac Newton was born in Lincolnshire, on December 25, 1642. He was educated at Trinity College in Cambridge, and resided at that place from 1661 to 1696 during which clip he produced the bulk of his work in mathematics. During this…

Introduction Statics is a branch of Mechanics that studies the forces and their effects in rigid bodies in balance. Just like humans, objects and buildings need a skeleton too. This is known as the structure. Bridges, amusement parks, chairs, and many other objects that surround us, have structures, if they didn’t they wouldn’t be able…
