power supplies. They are widely used in different types of electronic devices such as battery charger, electric vehicles, and in portable devices like cellular phones, laptops, computers etc. In battery charging applications of hybrid plug in electric vehicles full bridge dc-dc converters are commonly used. The fundamental problem regarding the conventional full bridge DC/DC converter topology is the voltage spikes across output diodes due to

Analyzing Due Process in the Workplace ELIHU M. GERSON AND SUSAN LEIGH STAR Tremont Research Institute Every office is an open system, and the products of office work are the result of decentralized negotiations. Changing patterns of task organization and alliance inevitably give rise to inconsistent knowledge bases and procedures. This implies that there are no globally correct answers to problems addressed by OIL%. Rather, systems must deal with multiple competing, possibly irreconcilable

DAME TALS OF COMPUTERS We are living in an information age dependent upon digital information. Digital information is electronic information, the result of computer processing. Every type of job relies upon getting information, using it, managing it, and relaying information to others. Computers enable the efficient processing and storage of information. Do not think of a computer merely as the machine with the keyboard and the mouse, although that might be true for some types of computers. Embedded

What is Human Services Wendy L. Coghill BSHS/302 April 6, 2013 Instructor Jean Holtz What is Human Services According to the National Organization of Human Services, “ The field of Human Services is broadly defined, uniquely approaching the objective of meeting human needs through an interdisciplinary knowledge base, focusing on prevention as well as remediation of problems, and maintaining a commitment to improving the overall quality of life of service populations (NOHS, 2013). The Human

Fluid Mechanics Learning Objectives Outcomes • Explain the pressure-depth relationship. Pressure increases with depth. • Define Pascal’s Principle. Pascal's Principle states that the pressure is transmitted evenly through a liquid. • Describe how to use Pascal’s Principle in practical application. When you inflate a balloon with air, it expands evenly in all directions, this is an example. • Describe Archimedes Principle. States that the mass of a liquid displaced by a floating body is

Kinetic Theory Objectives • Describe how the kinetic-molecular theory is used to explain how gases behave at different temperatures. (Exploration 1) • Analyze data that shows how gas particle mass affects that gas’s behavior. (Exploration 2) • Describe the Maxwell-Boltzmann Distribution. (Explorations 1 and 2) Description of Activity The kinetic-molecular theory states that a collection of gas molecules’ average kinetic energy has a specific value at any given temperature

Magna Carta The Magna Carta is often thought of as the cornerstone of liberty and a defense against unjust rule in England. The Magna Carta is also a type of constitution. Just like the English have the Magna Carta, the Americans have the Constitution. To better describe the Magna Carta I’m going to tell you some more about the line of events that led up to this famous document. First there was the landing of the pilgrims in 1620 at the Plymoth Rock “for the glory of god and the advancement

Problems for February 23, 2000 Problem 2. Microwaves in a microwave oven are produced by electrons circling in a magnetic field at a frequency of 2.4 GHz. a) What is the magnetic field strength? b) The electrons’ motion takes place inside a special tube called a magnetron. If the magnetron can accommodate electron orbits with a maximum diameter of 2.5 mm, what is the maximum electron energy? Problem 3. An electron moves in a circular path perpendicular to a constant magnetic
