Space Gear in Action (An Augmented Reality Experience) by Rebecca E. Hirsch Pdf
Explore outer space through interactive augmented reality experiences! Space suits protect astronauts during launches and landings and allow people to go on space walks. But astronauts need a lot more gear than just their suits to complete missions. Sometimes, they build their own tools in space using 3D printers. Augmented reality features add to this exciting exploration of space gear.
"Astronauts need a lot of gear to complete missions. They can even build their own gear in space using 3D printers. Augmented reality makes space come alive in this exciting adventure"--
From the earliest days of flight, design of comfortable yet protective flying clothing has proved almost as great a challenge as the creation of airplanes and spacecraft. With more than 150 illustrations, this volume shows how researchers and designers culled life-saving ideas from sources both expected and obscure: deep-sea divers' equipment, pressurized inner tubes, tomato worms, and medieval armor.
The Peacekeepers by Gene Dewese,Gene DeWeese,Deweese Pdf
Exploring a deserted alien spaceship, Lt. Commander Data and Lt. Geordi LaForge suddenly find themselves transported light-years away -- into the middle of a deadly conflict! While Captain Picard and the crew of the "U.S.S. Enterprise(TM) " search feverishly for the missing crewmen, Data and LaForge discover they are in a station almost identical to the one they were exploring, high in orbit around an earth-type world. Years before, the occupants of that planet accidentally stumbled onto the ship and its advanced technology -- and since then have used its weapons to keep the nations on the planet below disarmed, and at peace. Now their own arrival has precipitated a crisis on the station. Somehow, data and LaForge must find a way to restore trust between the planet below and the station's guardians up above -- before a final, destructive war breaks out!

To most mechanics a gear is a gear."A yellow primrose by the shore, A yellow primrose was, to him And it was nothing more;"And, in fact, the gear is often a gear and nothing more, sometimes barely that. But, if the mechanic will look beyond the tips of his fingers, he will find that it can be something more; that it is one of the most interesting objects in the field of science research, and not the simplest one; that it has received the attention of may celebrated mathematicians and engineers; and that the study of its features will not only add to his practical knowledge, but also to his entertainment. There is an element in mathematics, and in its near relative, theoretical mechanics, that possesses an educating and disciplining value beyond any capacity for earning present money. The thinking, inquisitive student of the day is the successful engineer or manufacturer of the future. The book is filled with wonderful turn of the century illustrations of gear wheels and gear cutting of every description.
Starring internationally renowned actors Martin Landau, Barbara Bain, Barry Morse and Catherine Schell, the British–made Space: 1999 was the only truly original space adventure of the mid–1970s. Sandwiched between the demise of the original Star Trek and the opening of the Stars Wars series on the big screen, Space: 1999 featured a richly-visualized world where space was terrifying and mysterious, where not all problems were solvable by technology and the space travelers were very human. From the science fiction show’s conception in 1973 to its cancellation in 1977, this reference work covers each of the 48 episodes in depth, including a full plot synopsis, writer, director, guest star credits, and critical commentary that examines both the episode and other shows that have used similar plotlines. The popularity of Space: 1999 memorabilia and its many fan clubs are fully discussed, along with the possibility of a future movie or reunion show that would tie up the loose ends caused by the show’s abrupt cancellation.
Goal-Directed Decision Making by Richard W. Morris,Aaron Bornstein,Amitai Shenhav Pdf
Goal-Directed Decision Making: Computations and Neural Circuits examines the role of goal-directed choice. It begins with an examination of the computations performed by associated circuits, but then moves on to in-depth examinations on how goal-directed learning interacts with other forms of choice and response selection. This is the only book that embraces the multidisciplinary nature of this area of decision-making, integrating our knowledge of goal-directed decision-making from basic, computational, clinical, and ethology research into a single resource that is invaluable for neuroscientists, psychologists and computer scientists alike. The book presents discussions on the broader field of decision-making and how it has expanded to incorporate ideas related to flexible behaviors, such as cognitive control, economic choice, and Bayesian inference, as well as the influences that motivation, context and cues have on behavior and decision-making. Details the neural circuits functionally involved in goal-directed decision-making and the computations these circuits perform Discusses changes in goal-directed decision-making spurred by development and disorders, and within real-world applications, including social contexts and addiction Synthesizes neuroscience, psychology and computer science research to offer a unique perspective on the central and emerging issues in goal-directed decision-making

Spaced Out! A Space Adventure by William Hairston Pdf
When I look back on my most recent space shuttle flight, I am convinced that my problems were most severe and uncommon. I have every right to be paranoid. There are simply times, exact and specific, when things go consistently against you; when bad luck is the only luck at hand; when, try as you might, you just can't change bad luck into good. And it seems that no one, or nothing, can really help you. I was blessed with a crew of four trained, seasoned and talented astronauts, but even their collective dedication and loyalty couldn't help me overcome the crisis and disasters I encountered. Merit and excellent qualifications were the basis on which my crew of astronauts and I were selected to command the Atlantis II space shuttle Mission, which had been originally scheduled to be second in line to launch five months before the terrible Challenger tragedy occurred in January, 1986, killing all seven of its crew-six astronauts and one schoolteacher-just one minute and thirteen seconds after a rather successful liftoff from its Cape Canaveral launch pad.

A little-known yet critical part of NASA history Life in Space explores the many aspects and outcomes of NASA’s research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASA’s work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush’s Vision for Space Exploration in the early twenty-first century. At the first flight of NASA’s space shuttle in 1981, hopes ran high for the shuttle program to achieve its potential of regularly transporting humans, cargo, and scientific experiments between Earth and the International Space Station. Mackowski describes different programs, projects, and policies initiated across NASA centers and headquarters in the following decades to advance research into human safety and habitation, plant and animal biology, and commercial biomaterials. Mackowski illuminates these ventures in fascinating detail by drawing on rare archival sources, oral histories, interviews, and site visits. While highlighting significant achievements and innovations such as space radiation research and the Neurolab Spacelab Mission, Mackowski reveals frustrations—lost opportunities, stagnation, and dead ends—stemming from frequent changes in presidential administrations and policies. For today’s dreams of lunar outposts or long-term spaceflight to become reality, Mackowski argues, a robust program in space life sciences is essential, and the history in this book offers lessons to help prevent leaving more expectations unfulfilled.

Deep Reinforcement Learning-based Energy Management for Hybrid Electric Vehicles by Yeuching Li,Hongwen He Pdf
The urgent need for vehicle electrification and improvement in fuel efficiency has gained increasing attention worldwide. Regarding this concern, the solution of hybrid vehicle systems has proven its value from academic research and industry applications, where energy management plays a key role in taking full advantage of hybrid electric vehicles (HEVs). There are many well-established energy management approaches, ranging from rules-based strategies to optimization-based methods, that can provide diverse options to achieve higher fuel economy performance. However, the research scope for energy management is still expanding with the development of intelligent transportation systems and the improvement in onboard sensing and computing resources. Owing to the boom in machine learning, especially deep learning and deep reinforcement learning (DRL), research on learning-based energy management strategies (EMSs) is gradually gaining more momentum. They have shown great promise in not only being capable of dealing with big data, but also in generalizing previously learned rules to new scenarios without complex manually tunning. Focusing on learning-based energy management with DRL as the core, this book begins with an introduction to the background of DRL in HEV energy management. The strengths and limitations of typical DRL-based EMSs are identified according to the types of state space and action space in energy management. Accordingly, value-based, policy gradient-based, and hybrid action space-oriented energy management methods via DRL are discussed, respectively. Finally, a general online integration scheme for DRL-based EMS is described to bridge the gap between strategy learning in the simulator and strategy deployment on the vehicle controller.
