The subject selected for this 2013 study is the Space Elevator Tether Climber. The objective of the one year study was to survey current concepts and technologies related to tether climbers, identify critical issues, questions, and concerns, assess their impact on the development of space elevators, and project towards the future. The following are a few of the conclusions: - The study used the concept of "constant power" as a baseline because of its ability to lower design requirements on the tether climber. - The mass breakout of 6 MT for a climber and 14 MT for customer payloads seems feasible. The estimate is that with a travel time of one week to GEO seven tether climbers can be on a tether simultaneously. - The communication architecture should be integrated into the space elevator infrastructure and nodal layout. - Solar power, as the sole source, appears achievable. - The use of laser power as the sole source also seems achievable.
In the last year, the International Space Elevator Consortium assessed that basic technological needs can be met with current capabilities: and, each segment of the Space Elevator Transportation System is ready for engineering validation. Because of the availability of a new material as a potential Space Elevator tether, the community strongly believes that a Space Elevator will be initiated in the near term. Included in the book is a series of appendices that are tremendous references to the status of the space elevator today. Included are a lexicon of space elevator terms, over 750 references in the bibliography, short descriptions of eight ISEC year-long studies and two IAA 4-year studies on space elevators, as well as a summary of over 20 Architectural Notes covering the development of space elevator technologies.
The International Space Elevator Consortium conducted a year-long study on the development of a space elevator Earth Port. This report addresses the functional requirements and missions leading to a mature engineering complex along the equator. The report represents the culmination of efforts by multiple contributors describing the functions and operations of the Earth Port and how it interacts with other space elevator nodes. The challenge was to bring in a fresh perspective on an Earth Port by leveraging experts in many fields beyond those normally associated with space elevators. As a result of the contributions from a variety of professional backgrounds, this study should reflect a more realistic perspective of the activities at the Earth Port of a future space elevator.
This study was designed to take the concept of Space Elevators and answer some questions relative to space debris. The team built upon the 2010 study on the topic and addressed many other issues to include: - The probabilities of orbital conjunctions between a space elevator and debris in Low Earth Orbit, Geo Earth Orbit, and Medium Earth Orbit. - The growth rate of space debris as it threatens operational space elevator (2010, 2019, 2030)? - Mitigation of risk for the space community through design, policies, operations, and lowering the threat. This year's study topic focused upon calculations for potential conjunction probabilities from densities of debris for 2010, 2019, and 2030. ""Space debris mitigation is an engineering problem with definable quantities such as density of debris and lengths/widths of targets. With proper knowledge and good operational procedures, the threat of space debris is not a show-stopper. However, mitigation approaches must be accepted and implemented robustly.
A complete introduction to analyzing and enjoying a wide variety of movies, for film students and movie lovers alike Thinking About Movies: Watching, Questioning, Enjoying, Fourth Edition is a thorough overview of movie analysis designed to enlighten both students and enthusiasts, and heighten their enjoyment of films. Readers will delve into the process of thinking about movies critically and analytically, and find how doing so can greatly enhance the pleasure of watching movies. Divided roughly into two parts, the book addresses film studies within the context of the dynamics of cinema, before moving on to a broader analysis of the relationship of films to the larger social, cultural, and industrial issues informing them. This updated fourth edition includes an entirely new section devoted to a complete analysis of the film adaptation of The Girl with the Dragon Tattoo, along with many in-depth discussions of important films such as Citizen Kane and Silence of the Lambs. The chapter on television integrates a major expansion distinguishing between television in the digital era of the convergence of the entertainment and technology industries in comparison to the era of broadcast analogue television. The final chapter places film within the current context of digital culture, globalization, and the powerful rise of China in film production and exhibition. The authors clearly present various methodologies for analyzing movies and illustrate them with detailed examples and images from a wide range of films from cult classics to big-budget, award-winning movies. This helps viewers see new things in movies and also better understand and explain why they like some better than others. Thinking About Movies: Watching, Questioning, Enjoying, Fourth Edition is ideal for film students immersed in the study of this important, contemporary medium and art form as well as students and readers who have never taken a class on cinema before.
This book focuses on the tactics and strategies used in business-to-business contract negotiations. In addition to outlining general negotiation concepts, techniques and tools, it provides insight into relevant framework conditions, underlying mechanisms and also presents generally occurring terms and problems. Moreover, different negotiating styles are illustrated using an exemplary presentation of negotiation peculiarities in China, the USA and Germany. The presented tactics and strategies combine interdisciplinary psychological and economic knowledge as well as findings from the field of communication science. The application scope of these tactics and strategies covers business-to-business negotiations as well as company-internal negotiations. The fact that this book does not necessarily stipulate any prior knowledge of the subject of negotiations also makes it highly suitable for nonprofessionals with a pronounced interested in negotiations. Nonetheless, it provides proficient negotiators with a deeper understanding for situations experienced in negotiations. This book also helps practioners to identify underlying mechanisms and on this basis sustainably improve their negotiation skills.
This ground-breaking Research Handbook provides a state-of-the-art discussion of the international law of Indigenous rights and how it has developed in recent decades. Drawing from their extensive knowledge of the topic, leading scholars provide strong general coverage and highlight the challenges and cutting-edge issues arising in international Indigenous rights law.
The Handbook of Logistics and Distribution Management provides an introduction to fundamental elements of modern logistics and distribution. It explores all stages of the supply chain from raw materials through to the final distribution of the finished product. This handbook covers vital areas, including: concepts of logistics and distribution; planning for logistics; procurement and inventory decisions; warehousing and storage; freight transport; and operational management. The 5th edition of The Handbook of Logistics and Distribution Management has been radically updated to reflect the latest advances in logistics and covers new topics studied on academic and professional courses. There are brand new chapters on humanitarian logistics, multichannel fulfilment and reverse logistics, as well as detailed discussion of the latest trends and issues that confront logistics. The Handbook of Logistics and Distribution Management is a practical handbook and an essential reference for logistics and supply chain practitioners as well as students undertaking professional examinations and degrees in the field of logistics and supply chain.
The study team took on the challenge of expanding the "body of knowledge" pertaining to the Apex and Geosynchronous elements of the Space Elevator. A special effort was made to describe the elements in the context of an entire Space Elevator. The report complements and expands earlier ISEC Space Elevator reports on the Climber, Operations Concept, Architectures & Roadmaps, and Earth Port. To do so, we have established; 1. A robust set of definitions within the Geosynchronous and Apex Regions, and 2. The Strategic Approach to Architectural Development of a Space Elevator
