William H. Paloski, Ph. D. Human Adaptation and Countermeasures Office NASA Johnson Space Center Artificial gravity is an old concept, having gotten its start in the late in the 19th century when Konstantin Tsiolkovsky, considered by many to be the father of the Russian space program, realized that the human body might not respond well to the free fall of orbital space flight. To solve this problem, he proposed that space stations be rotated to create centripetal accelerations that might provide inertial loading similar to terrestrial gravitational loading. Einstein later showed in his...

In this testament to the distinguished career of H.S. Houthakker a number of Professor Houthakker's friends, former colleagues and former students offer essays which build upon and extend his many contributions to economics in aggregation, consumption, growth and trade. Among the many distinguished contributors are Paul Samuelson, Werner Hildenbrand, John Muellbauer and Lester Telser. The book also includes four previously unpublished papers and notes by its distinguished dedicatee.

Creativity is one of the least understood aspects of intelligence and is often seen as intuitive' and not susceptible to rational enquiry. Recently, however, there has been a resurgence of interest in the area, principally in artificial intelligence and cognitive science, but also in psychology, philosophy, computer science, logic, mathematics, sociology, and architecture and design. This volume brings this work together and provides an overview of this rapidly developing field. It addresses a range of issues. Can computers be creative? Can they help us to understand human creativity? How can...

In Everyday Conceptions of Emotion, prominent anthropologists, linguists and psychologists come together for the first time to discuss how emotions are conceptualised by people of different cultures and ages, speaking different languages. Anger, fear, jealousy and emotion itself are concepts that are bound up with the English language, embedded in a way of thinking, acting and speaking. At the same time, the metaphors underlying such concepts are often similar across languages, and children of different cultures follow common developmental pathways. The book thus discusses the...

Reducing Space Mission Cost is the first complete treatment of the technology, process, and problems in the most critical areas of modern spaceflight. The demand to reduce cost is unrelenting. This pioneering book addresses all aspects of this problem, including:

• Technology and processes for reducing cost
• Cost reduction in mission engineering, spacecraft design, manufacture, launch, and operations
• Implementation methods and problems
• The price of reducing cost
• 10 detailed case studies of what works in practice in:
  • Science missions
  ...

This third edition of Space mission analysis and design carries on the tradition of the first two editions of providing a practical handbook for space mission engineering' - the process of defining mission parameters and refining requirements to meet the often fuzzy objectives of a space mission at minimum cost and risk. SMAD III both updates the technology and provides a greater emphasis on the design of smaller spacecraft and the process of reducing cost. It hasbeen expanded to include more detail of multi-satellite manufacturing and the design and selection of constellation parameters. The...

Der vorliegende Band enthalt Husserls einzige weitgehend vollstandig erhaltene Vorlesung aus seiner Hallenser Zeit, die er 1896 unter dem Titel Logik' gehalten und im Hinblick auf eine Veroffentlichung teilweise bearbeitet hat. Dieses husserlsche Buchprojekt wird hier der Offentlichkeit zum ersten Mal zuganglich gemacht. In der Vorlesung entwirft Husserl hauptsachlich eine in den Logischen Untersuchungen zwar angekundigte, aber nicht mehr realisierte objektive Logik, die sich in Idee und Terminologie eng an Bolzano anschliesst. Die einleitenden Bemerkungen der Vorlesung uber...

Mission Geometry; Orbit and Constellation Design and Management (OCDM) is the most complete treatment available for many elements of space mission design and astronautics. Among these topics not covered elsewhere in the literature are:

• The most extensive coverage available of constellation design and management;
• Relative motion of satellites (global, local, at similar and widely differing altitudes);
• Definition of an Orbit Cost Function for comparing the cost of access to and maintenance of alternative orbits;...

This book focuses on the interrelationship of social, technical, and organizational aspects of and related to the product development process. It originated from activities in practice in industry and research laboratories. In order to ensure relative autonomy from the short-term economic interests of a given industrial branch or specific company, the research for this work was first conducted in pursuit of a PhD thesis intended to provide practice-oriented results. With the ansatz practice - theory - practice, a generalizable approach was achieved. It then evolved to cover additional issues...

The present book Essential Spaceflight Dynamics and Magnetospherics describes, in the first instance, some of the key aspects of celestial mechanics and spaceflight dynamics. It begins with classical two and three body problems illustrative of the aesthetic aspects of applying analytical methods of investigation to celestial mechanics. Then, osculating orbital elements are introduced as well as analysis techniques sufficient to evaluate the influence of various disturbing forces on spacecraft. Next a theory of manoeuvres is outlined and the methodology of making...
