United States Diplomatic Codes and Ciphers, 1775-1938 is the first basic reference work on American diplomatic cryptography. Weber's research in national and private archives in the Americas and Europe has uncovered more than one hundred codes and ciphers. Beginning with the American Revolution, these secret systems masked confidential diplomatic correspondence and reports.During the period between 1775 and 1938, both codes and ciphers were employed. Ciphers were frequently used for American diplomatic and military correspondence during the American Revolution. At that time, a system was popular among American statesmen whereby a common book, such as a specific dictionary,was used by two correspondents who encoded each word in a message with three numbers. In this system, the first number indicated the page of the book, the second the line in the book, and the third the position of the plain text word on that line counting from the left. Codes provided the most common secret language basis for the entire nineteenth century.Ralph Weber describes in eight chapters the development of American cryptographic practice. The codes and ciphers published in the text and appendix will enable historians and others to read secret State Department dispatches before 1876, and explain code designs after that year.
Events at Pearl Harbor angered 9th grade English teacher Norman Edward Robinson. At the age of 34 he left his teaching job at the school (in Monmouth, Indiana,) and joined the United States Navy. While he was gone, from 1942-1945 the school held his job open. School officials promised that his teaching job would still be waiting for him when he eventually returned from the war. He traveled with the U.S. Navy as a Pharmacist First Mate to many countries, just a few of them being: Bougainville, Guadalcanal, Hawaii, The New Hebrides, New Zealand, Pago Pago, the Panama Canal, Philippines and Samoa. He participated in training exercises on islands such as: Efati and Espirito Santos prior to being sent to Bougainville. Mate Robinson also served (and wore stars) for his service in the battlefields at both Pivi Village and Pivi forks. The opening Biography section explores the permanent relocation of his entire family from Belfast, Ireland to their new residence located at 2515 E. Riverside Drive in Indianapolis, Indiana. It was in the year of (1910.) It delves deeply into his other immediate family members giving explanations of how their relationships intertwined. Outlines of Normans many educational accomplishments prior to those war years appear. It was his long time girl friend (of 9 years, Mary Katherine Mitchell) that waited so patiently for him to return after W.W. II in Indianapolis, Indiana. You will be reading much more about their bitter/sweet relationship in the later part of the book. This book gives some glimpses interspersed with family stories, pictures, weather conditions and recipes describing the everyday routine daily life of those war years from 1941-1945. Narratives of the letters that flew back and forth with his family members, church friends and neighbors while he was serving are also included.

Written by an author who has devoted the past twenty-five years ofhis life to studying and designing shock wave engines, this uniquebook offers comprehensive coverage of the theory and practice ofshock wave engine design. The only book treating the completepreliminary design of shock wave engines, it provides engineerswith practical step-by-step guidelines applicable to the design andconstruction of small, light- weight, low-powered industrialturbines as well as high performance jet aircraft engines. In his discussions of the advantages and disadvantages of shockwave versus other types of combustion engines, Dr. Weberdemonstrates how and why shock wave engines can be made to workmore efficiently than conventional gas turbines. Among otherthings, he shows quantitatively why combustion temperatures can besignificantly higher in shock wave engines than conventional gasturbines. He evaluates temperatures of moving parts in terms ofcombustion and engine inlet temperatures, and explores the effectof shock coalescence, expansion fan reflections and intersectionson port sizes and locations. And throughout, real and imaginedperformance problems are posed and proven solutions given for shockwave engines--alone and in conjunction with conventional gasturbines or reciprocating internal combustion engines. Designed to function as a practical guide, Shock Wave Engine Designoffers concise step-by-step design techniques in a readily usableformat. Engineers will find precise, detailed directions on suchessentials as how to size wave rotor blade lengths and heights andthe correct rotor diameter for a specified power, and materialselection for rotor and stator. And one entire chapter (Chapter 12)is devoted exclusively to a detailed example design for a 500 hpengine. An authoritative, highly practical guide to state-of-the-art shockwave engine design, this book is an important resource formechanical and aerospace engineers who design aircraft engines orvirtually any type of turbomachinery. Timely, authoritative, practical--an important resource forengineers who design aircraft engines or virtually any type ofturbomachinery Written by a pioneer in the field, this book offers a comprehensivecoverage of state-of-the-art shock wave engine design principlesand techniques. The only book treating the complete preliminarydesign of shock wave engines, this unique guide provides engineerswith: * Concise step-by-step guidelines applicable to the design andconstruction of small, lightweight, low-powered industrial turbinesas well as high-performance jet aircraft engines * In-depth treatments of pressure exchangers, wave engines, andwave engines compounded with reciprocating IC engines * A chapter-length example design for a 500 hp engine * A brief but thorough review of all essential thermodynamics andgas dynamics needed to develop flow equations and calculationmethods
Critical Thinking and American Government contains 41 critical thinking exercises that use a wide variety sources to actively engage students in understanding and thinking critically about American government and politics. These sources include court decisions, the Federalist Papers, legislation, public opinion polls, elections results, apportionment and population tables, data on topics such as African-American representation in Congress, among many others. The critical thinking exercises require students to interpret and analyze data, discover basic relationships among variables, read critically, summarize information accurately, and formulate generalizations and hypotheses. The exercises are based on the scholarship of teaching and learning. Each exercises contains clear and discrete student learning objectives which facilitate the measurement and assessment of student outcomes and learning.
SUNNY DAYS AND RAIN is the dramatic story of two young boys and thier ability to cope as thier lives and friendships change. The play is the classic tale of growing up and growing apart mixed with a contemporary humor designed to draw in audiences from all walks of life. People who watch or read this play are instantaneously drawn to its simplicity and its ability to connect to thier own experiences. No one ever claimed that growing up was easy, but it is something that everyone must do no matter how hard they fight it. 2 males, 2 females (age range: 15-22)
