Taschenbuch. Zustand: Neu. Neuware - The satellite industry is driven by the need to reduce costs. One way they have sought to do this is by reducing the size and weight of the satellite because of the extremely high cost per kilogram incurred launching a payload into orbit. The main difficulty in this approach is the lack of power capacity in a small satellite. One of the largest loads on a satellite's power system is the communications system. This has driven the need for a low-power communications system. This document examines a novel method of communicating optically with a low-Earth-orbit satellite from the ground without the need for a laser on the payload. The goal is to show the feasibility of such a system as a solution to the small satellite low-powered communication problem. Specially, that the system described herein: is capable of ground to low-Earth-orbit communications, has very little space-borne mass, and draws little power from the satellite. First, the system (hereafter referred to as LOWCAL 'Lightweight Optical Wavelength Communication without A Laser in space') will be explained with details of the formats used and the link budgets. Discussions will be presented on the development of some of the system hardware (the laser diode driver, liquid crystal driver, and decision electronics for both the up and down links.) Finally, experimental test results of the entire system operating in a laboratory environment are presented and compared to theory. The results of the laboratory experiment support the original thesis: retro-modulated optical communications can meet the needs of the small satellite community. The system is capable of 10-kbps communication, has low space-borne mass, and draws little power from the satellite (less than 100-mW measured for the laboratory experiment, less than 1.5-W calculated for the Shuttle experiment).This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.

Taschenbuch. Zustand: Neu. Neuware - In Under Prairie Skies, C. Thomas Shay asks and answers the question, What role did plants play in the lives of early inhabitants of the northern Great Plains Since humans arrived at the end of the Ice Age, plants played important roles as Native peoples learned which were valuable foods, which held medicinal value, and which were best for crafts. Incorporating Native voices, ethnobotanical studies, personal stories, and research techniques, Under Prairie Skies shows how, since the end of the Ice Age, plants have held a central place in the lives of Native peoples. Eventually some groups cultivated seed-bearing annuals and, later, fields of maize and other crops. Throughout history, their lives became linked with the land, both materially and spiritually.…

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - Essay from the year 2013 in the subject History Europe - Other Countries - Ages of World Wars, grade: A, Memorial University of Newfoundland (Memorial University of Newfoundland), language: English, abstract: The Origins of the Blitzkrieg is a brief examination of the evolution of strategy and tactics that paved the way to one of the most successful styled campaigns in warfare. Popularly employed to devastating success in the Second World War, Blitzkrieg's history simply did not begin from the thinkers of the interwar period, its origins stem even further back.An extremely likely outcome during an era when both sides of the conflict struggled initially to make sense of new advanced weapons of war. This paper not only briefly examines the struggle of the Central Powers and Allies in trying to reconcile the many stalemates of the war, but also outlining coupled with analysis of the very foundations of what would later be pieced together in its totality as lightning war.…
