Описание: The object of this book is to teach the beginner the basics of three popular power system analysis programs. These programs are designed to simulate and analyze electrical power generation and distribution systems in normal operation and in short-circuit. The programs also have many add-on options like protection selection, arc flash analysis, transmission line sag & tension, raceway calculations, transient motor starting, etc. The programs have Demo (demonstration or trial) versions to allow people to tryout and learn about them. This book provides the engineer and technologist with information needed to use the Demo versions of SKM, ETAP, and EDSA for load flow and short-circuit analysis. The beginner learns how to use them on a small, but realistic, three-phase power system. The information gained is similar to that which students pay for in company-taught "Introduction to ..." courses. However, with this book, the student avoids paying tuition, learns at times of his own convenience, and can compare the different programs. In this book, load flow (power-flow) and short-circuit analyses are done on a small steady-state three-phase power system with manual methods. Then, each program is used to carry out the same analyses. Since in practice, three-phase systems are the most often analyzed, only three-phase systems will be considered in this book. The DC and single-phase capabilities of the programs will not be considered. The person using this book should already have an analytical electrical background. Academically, he should be educated to at least the level of a university two-year electrical engineering technology program.

Описание: For many people at midlife the pace of life is so frenetic and full that we do not take the time to "let the land lie fallow." But it is especially at this juncture that many want to ask some hard questions of God and of ourselves.

46 Years
"It's been forty-six years since I left Vietnam."
--Mark W. Olver, 2014
Framed as a novel, 46 Years introduces Mark W. Olver, one smart, funny, young man and how he endured during the harrowing years of 1966-1969 while a foot soldier in the Vietnam War. As a member of Delta Company, First Battalion, 26th Infantry, First Infantry Division, nineteen-year-old Mark--from rural Pennsylvania--provides the bulk of the novel through descriptive, sometimes humorous, but often shocking letters written to his mom after being drafted. A fact-based narrative created from interviews with an older Mark and his mom, frames the letters, providing a rich, candid experience of one young soldier. During his time in country, Mark finds himself in a culture foreign to him and unknowingly begins a steady stream of information-filled letters so moving that his mom is carried along with him each step of the way, a trail of his long journey, of living in dugout holes, of cutting trails through the jungle mire, and the relentless monotony of military life. Often simply a note, this steadfast retelling of the day's or week's events serve as that tether or bond to the real world of family and friends for Mark, a documented story of how our young infantrymen must have endured. Mark writes home more letters than anyone he knows, that is, until the unthinkable occurs on April 23, 1968, when an enemy mortar attack changes his life once again, this time forever. All this time, Mark has no idea that while away his mom saves every letter, every scrap. Now a Purple Heart recipient and disabled veteran, Mark looks back at the letters and speaks out about the effects on one human life--his own. From long ago and far away, this story reaches out to today's readers through the innocent letters of an American boy forty-six years ago.

Описание: Military intervention short of full scale war is not a new phenomenon as a means of pursuing national interests. With the end of the cold war, military intervention has taken a new twist in the form of peace operations. The United States Air Force (USAF) in particular is being used as a tool of national policy in peace enforcement operations with increasing regularity. The USAF was involved in the conflict in the former Yugoslavia and maintained an air presence in both Turkey and Saudi Arabia to control the Iraqi repression of its civilian population. This involvement raised a fundamental question about when and how airpower should be used as an effective coercive force in peace enforcement operations. Peace enforcement is a military intervention in an ongoing conflict that uses military force to coerce one or more belligerents to comply with mandated restrictions. The purpose of this intervention is to create the proper security conditions such that other peace efforts such as humanitarian relief and diplomatic peacemaking can help the belligerents resolve the conflict without the use of force. This study uses Operation Provide Comfort in northern Iraq and the Unified Taskforce/United Nations Operations in Somalia II (UNITAF/UNOSOM II) as case studies to examine how airpower influenced these peace enforcement operations.
