Mars, like planet Earth, is a complex and vast world with a long history. The authors of this book give a new insight of Mars by adopting an original outline based on history rather than on subtopic (atmosphere, surface, interior). They focus on the past and present evolution of Mars and also incorporate all the recent results from the space missions of Mars Express, Spirit and Opportunity. This book goes to the heart of current planetological research, and illustrates it with many beautiful images. |

When one thinks of Mach 3 aircraft, what generally comes to mind is the Lockheed SR-71 or perhaps the MiG 25. But there was another Mach 3 design, one that was a good deal larger and five times heavier than the Blackbird or the Foxbat. Perhaps even more futuristic looking, the North American Aviation XB-70A Valkyrie was the culmination of General Curtis LeMay's quest for the ultimate strategic bomber. |

Iam writing this from Las Vegas, where our Renewable Energy World North America event has just taken place. Meanwhile, across the ocean (and much closer to my usual UK home) the world’s leading climate scientists have been gathered in Copenhagen at a conference entitled Climate Change: Global Risks, Challenges and Decisions. Primarily a scientific rather than political gathering, it paves the way for COP 12, which takes place in Copenhagen in December. |

Multiple-input multiple-output (MIMO) radar has been receiving increasing attention in recent years from researchers, practitioners, and funding agencies. MIMO radar is characterized by using multiple antennas to simultaneously transmit diverse (possibly linearly independent) waveforms and by utilizing multiple antennas to receive the reflected signals. Like MIMO communications, MIMO radar offers a new paradigm for signal processing research. |

Industrial robots for working in factory environment were widely researched and lead enormous development in the 20th century. But the research subjects are moving to Service Robotics with the busy life style of humans in the 21st century. Humans have great concern in healthy life and do not want to get 3D jobs (difficult, dangerous and dirty) as well as repeated simple jobs. For these reasons, Service Robots which do these jobs instead of humans are the main focus of research nowadays. |

The first robots (they were called automatons in those days) were purely mechanical, driven by clockwork or steam power. The arrival of electronics greatly increased the scope of what robots could be made to do. Modern concepts of robotics began to emerge. The big advances came when engineers started putting complex digitial circuitry on a single chip. These were microprocessors, capable of millions of operations per second. Microprocessors are widely used in computers, robots, and many other devices that depend on high-speed, digital processing. |

This book is an account of the physics of radiation and its interaction with matter in a particular spectral region, I t is concerned with physical principles as they relate to far-infrared electromagnetic waves. In studying physics from such a point of view one naturally cuts across many of the usual boundaries of specialist research, but, in a field that has been beset by a sea of experimental difficulties, it is particularly desirable to be familiar with many, or most, aspects of the field. |

Neuroscience has discovered that our brain’s very design makes it sociable, inexorably drawn into an intimate brain-to-brain linkup whenever we engage with another person. That neural bridge lets us impact the brain—and so the body—of everyone we interact with, just as they do us. Even our most routine encounters act as regulators in the brain, priming emotions in us, some desirable, others not. The more strongly connected we are with someone emotionally, the greater the mutual force.

The source of linear algebra is the solution of systems of linear algebraic equations. Linear algebra is the foundation upon which almost all applied mathematics rests. This is not to say that nonlinear equations are less important; rather, progress in the vastly more complicated nonlinear realm is impossible without a ¯rm grasp of the fundamentals of linear systems. Furthermore, linear algebra underlies the numerical analysis of continuous systems, both linear and nonlinear, which are typically modeled by di®erential equations. |

Feng shui (Science of Wind and Water) has been known in the West for the last 150 years but has mostly been regarded as a primitive superstition. During the modern period, successive regimes in China have suppressed its practice. However, in the last few decades, feng shui has become a global spiritual movement with professional associations, thousands of titles published on the subject, countless websites devoted to it andmillions of users. |
