Book Description
This book contains mechanism analysis and synthesis. In mechanism analysis, a mobility methodology is first systematically presented. This methodology, based on the author's screw theory, proposed in 1997, of which the generality and validity was only proved recently, is a very complex issue, researched by various scientists over the last 150 years. The principle of kinematic influence coefficient and its latest developments are described. This principle is suitable for kinematic analysis of various 6-DOF and lower-mobility parallel manipulators. The singularities are classified by a new point of view, and progress in position-singularity and orientation-singularity is stated. In addition, the concept of over-determinate input is proposed and a new method of force analysis based on screw theory is presented. In mechanism synthesis, the synthesis for spatial parallel mechanisms is discussed, and the synthesis method of difficult 4-DOF and 5-DOF symmetric mechanisms, which was first put forward by the author in 2002, is introduced in detail. Besides, the three-order screw system and its space distribution of the kinematic screws for infinite possible motions of lower mobility mechanisms are both analyzed.

Book Description
Locality is a fundamental restriction in nature. On the other hand, adaptive complex systems, life in particular, exhibit a sense of permanence and time lessness amidst relentless constant changes in surrounding environments that make the global properties of the physical world the most important problems in understanding their nature and structure. Thus, much of the differential and integral Calculus deals with the problem of passing from local information (as expressed, for example, by a differential equation, or the contour of a region) to global features of a system's behavior (an equation of growth, or an area). Fundamental laws in the exact sciences seek to express the observable global behavior of physical objects through equations about local interaction of their components, on the assumption that the continuum is the most accurate model of physical reality. Paradoxically, much of modern physics calls for a fundamen tal discrete component in our understanding of the physical world. Useful computational models must be eventually constructed in hardware, and as such can only be based on local interaction of simple processing elements.

Book Description
Motivation It is now possible to build powerful single-processor and multiprocessor systems and use them efficiently for data processing, which has seen an explosive ex pansion in many areas of computer science and engineering. One approach to meeting the performance requirements of the applications has been to utilize the most powerful single-processor system that is available. When such a system does not provide the performance requirements, pipelined and parallel process ing structures can be employed. The concept of parallel processing is a depar ture from sequential processing. In sequential computation one processor is in volved and performs one operation at a time. On the other hand, in parallel computation several processors cooperate to solve a problem, which reduces computing time because several operations can be carried out simultaneously. Using several processors that work together on a given computation illustrates a new paradigm in computer problem solving which is completely different from sequential processing. From the practical point of view, this provides sufficient justification to investigate the concept of parallel processing and related issues, such as parallel algorithms. Parallel processing involves utilizing several factors, such as parallel architectures, parallel algorithms, parallel programming lan guages and performance analysis, which are strongly interrelated. In general, four steps are involved in performing a computational problem in parallel. The first step is to understand the nature of computations in the specific application domain.

Book Description
Semantics of Parallelism is the only book which provides a unified treatment of the non-interleaving approach to process semantics (as opposed to the interleaving approach of the process algebraists). Many results found in this book are collected for the first time outside conference and journal articles on the mathematics of non-interleaving semantics. It gives the reader a unified view of various attempts to model parallelism within one conceptual frame work. It is aimed at postgraduates in theoretical computer science and academics who are teaching and researching in the modelling of discrete, concurrent/distributed systems. Workers in the information technology industry who are interested in available theoretical studies on parallelism will also be interested in this book.

Book Description
Excerpt from Theories of Parallelism: An Historical Critique Haec hactenus... Some years ago I made use of this expression incidentally in the course of my annotated edition of the First Book of Euclid's Elements, with reference to an historical sketch of the Theory of Parallelism. After much hesitation and with much diffidence, somewhat augmented by the appearance (after the first draft of this little volume had been prepared) of Dr Heath's most learned and elaborate Thirteen Books of Euclid's Elements, I have here tried to disburden conscience and memory by drawing up in chronological order my notes on the treatment of parallelism by about 40 Geometers of rank. Except for the last generation, I believe that these 40 names are the most noteworthy throughout twenty-two centuries in this connexion. As is well known, any theory of parallelism is not an isolated fragment of geometrical research, but must be capable of supporting the whole superstructure of the Science of Space. And the historical study of this matter is interesting, not least because it displays, in a manner partly amusing and partly pathetic, the dulnesses, limitations, prejudices and aberrations of professedly logical minds. Frail and imperfect demonstrations were once viewed with considerable complacency. Up to the middle of last century the treatment of parallelism was a favourite lurking-place for paralogisms. Wonderful indeed is the serene illumination of Truth by which the student works in this twentieth century. Compared with it, the Renascence was only a stirring and awakening out of sleep in the dim twilight of the early dawn. If it is not impertinent in me to suggest it, we seem to be finding the Balance of Truth. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
This little book is not a text-book of psychology. It is exclusively concerned with one particular psychological problem, a problem, however, that stands at the very centre of psychology. The relations between mind and body are analysed; that is to say, the following three psychedelic problems are successively raised: What is the mind? What is the body? What are the relations between mind and body? But it is only the third problem which is extensively dealt with; the first two are only briefly defined.
