The purpose of the functional analysis was to determine Nuclear Weapons Complex (NWC) functions, relationships, and interdependenceis for National Nuclear Security Administration (NNSA) management and the Integrated Project Teams (IPTs) to enhance transformation decision-making. It was determined that decison-makers needed a tool for remaining cognizant of the various functions performed at the sites and ensuring that they were properly reallocated in each of the Supplemental Programmatic environmental Impact Statement PEIS) transformation alternatives. The NWC functional was a tool designed for this purpose. This functional analysis was prepared by the Systems Engineering & Integration (SE&I) group at the Savannah River Site and the Systems Integration Technical Support (SITS) organization at Sandia National Laboratories as the request of the NNSA Office of Transformation (NA-10.1). Functional analysis is the next step in the Systems Engineering process after setting goal and requirements. Functional analysis divides a system into smaller parts, called functional elements, which describe what we want each part to do. We do not include the how of the design or solution yet. At this point we don't want to limit the design choices, because it might leave out the best answer. In later steps we will identify alternatives, optimize them, and select the best ones to make up the complete system. The name Function comes from mathematical functions, which act on an input value and produce a different output value. Similarly, in the Systems Engineering method, functions transform a set of inputs to a set of outputs. The purpose of functional analysis is to divide a complex system into smaller and simpler parts, so that eventually they can be individually designed. One way to divide into parts is along the time axis. A large project can be divided into phases that are sequential in time, where each phase adds new capabilities. Technical projects are often divided into several design phases, production, testing, and delivery, where milestones for a given phase must be completed before going on to the next phase. Within a part of a system, some tasks must happen in a sequence or process in time order. So each step in the sequence can be identified as a function. Another way to divide functions up is when they do different things at the same time, but have inputs and outputs that connect them. There is no single answer for how best to divide up a system., Westinghouse Savannah River Corporation, 2007, 2.5, NY: Viking, 1985. Book. As New. Hardcover. We take numbers for granted. They are an integral part of our life. We use numbers to measure temperature, distances; ingredients for an experiment or for baking a cake; to communicate to a medical provider on how intense our pain is or the score of an important game. Numbers are everywhere.today. But where did the idea of numbers come from? Did the concept of numbers stem from a central civilization or develop simultaneously among various cultures? These are the questions the author attempts to answer. From the humble beginning of counting items to the most sophisticated mathematic equations, the author traces the development of numbers over the ages among well-known and little known ancient cultures.

"IMPACT" is his eighth book, is different from his earlier writings, and books. Sheppard was a young preteen boy throughout World War II. A then small Lee County, Florida, was home to two major Army Air Fields training facilities during the War, Page Field, and Buckingham Army Air Field. Sheppard's father, W.A. Sheppard who had served in the trenches during World War I, as a young man, at age 45, re- enlisted in the Army Infantry shortly after Pearl Harbor, leaving behind his wife, Mary and three children. John, the youngest son, tracked the progress of the War on all fronts, through the radio, newsreels, local newspaper, and magazines for three years. In this process through many local and Army contacts young John studied the criteria and capacity of and recognized by sight and sound each of every Army Air Force bomber and fighter planes that trained in Lee County. This included all of the major Army war planes of World War II, except the B-29. In addition through his mother Mary's "home front program" of bringing young soldiers to every Sunday dinner with the children, the family made many lasting friends and impacts with scores of young men. Sheppard weaves the connections to these people and events through historic and actual happenings of friendships and circumstances. Early in his book, the author explains the mathematical theory "Six Degrees of Separation," conceived in the 1920's, by which when carried out to six degrees, each of us, is connected with every other human being on the earth. His measured connections through people and events of both World Wars are never more than three degrees of separation from the author and his family. Sheppard as his Father, served in the Army Infantry. He praises the accomplishments of the men and women in the Armed Forces, past and present. And he recognizes the individuals through which the connections have come, and describes significant events and people locally connected, of both World Wars, that have heroically defended and contributed to the causes of both World Wars, and the fragile and broken peace that has followed each Wars. But, he leaves to the reader to contemplate the price paid over the last 100 years of many wars and continues to be paid in lives of the dead, the wounded, the survivors, the time, the unsettled issues, to all of the sides of the Wars, participants and non-participants alike, and the perilous place where the world is today. We have been the beneficiaries of those sacrifices. In the words of Irving Berlin's God Bless America, "While the storm clouds gather, far across the sea, let us pledge allegiance to a Land that's free." Many of the brave have kept us free, and even today we may be called on again, to defend our Homeland. Sheppard closes his book with the hope that somehow and in some time to come that the nations, and peoples of the world, all humankind can learn to live in peace, one with the other., CreateSpace Independent Publishing Platform (November 26, 2014), 2014-01-01, 3, Paperback / softback. New. Where do stars come from and how do they form? These are profound questions which link the nature of our Universe to the roots of mankind. Yet, until a recent revolution in understanding, the proposed answers have been raw speculation. Now, accompanying penetrating observations, a new picture has come into prominence.This book presents the latest astounding observations and scientific ideas covering star formation, star birth and early development. It encompasses all aspects, from the dramatic stories of individual objects, to the collective influence of entire stellar systems.The very first stars to come into existence and the nurturing of planets are discussed to provide the reader with a comprehensive overview. Presenting background information with only the essential mathematics, this book will appeal to scientists wishing to expand their horizons, students seeking solid foundations, and general readers with enquiring minds., 6<
