Buch. Condizione: Neu. Neuware - Since the classic studies of Woodworth (1899), the role ofvision in the control of movement has been an importantresearch topic in experimental psychology. While many earlystudies were concerned with the relative importance of visionand kinesthesis and/or the time it takes to use visualinformation, recent theoretical and technical developmentshave stimulated scientists to ask questions about howdifferent sources of visual information contribute to motorcontrol in different contexts.In this volume, articles arepresented that provide a broad coverage of the currentresearch and theory on vision and human motor learning andcontrol. Many of the contributors are colleagues that have metover the years at the meetings and conferences concerned withhuman movement. They represent a wide range of affiliation andbackground including kinesiology, physical education,neurophysiology, cognitive psychology and neuropsychology.Thus the topic of vision and motor control is addressed from anumber of different perspectives. In general, each author setsan empirical and theoretical framework for their topic, andthen discusses current work from their own laboratory, and howit fits into the larger context. A synthesis chapter at the end of the volume identifies commonalities in the work and suggests directions for future experimentation.…

Buch. Condizione: Neu. Neuware - In this revolutionary work, the author sets the stage for the science ofthe 21st Century, pursuing an unprecedented synthesis of fields previouslyconsidered unrelated. Beginning with simple classical concepts, he endswith a complex multidisciplinary theory requiring a high level ofabstraction. The work progresses across the sciences in severalmultidisciplinary directions: Mathematical logic, fundamental physics,computer science and the theory of intelligence. Extraordinarily enough,the author breaks new ground in all these fields.In the field offundamental physics the author reaches the revolutionary conclusion thatphysics can be viewed and studied as logic in a fundamental sense, ascompared with Einstein's view of physics as space-time geometry. This opensnew, exciting prospects for the study of fundamental interactions. Aformulation of logic in terms of matrix operators and logic vector spacesallows the author to tackle for the first time the intractable problem ofcognition in a scientific manner. In the same way as the findings ofHeisenberg and Dirac in the 1930s provided a conceptual and mathematicalfoundation for quantum physics, matrix operator logic supports an importantbreakthrough in the study of the physics of the mind, which is interpretedas a fractal of quantum mechanics. Introducing a concept of logic quantumnumbers, the author concludes that the problem of logic and theintelligence code in general can be effectively formulated as eigenvalueproblems similar to those of theoretical physics. With this important leapforward in the study of the mechanism of mind, the author concludes thatthe latter cannot be fully understood either within classical or quantumnotions. A higher-order covariant theory is required to accommodate thefundamental effect of high-level intelligence. The landmark resultsobtained by the author will have implications and repercussions for thevery foundations of science as a whole. Moreover, Stern's Matrix Logic issuitable for a broad spectrum of practical applications in contemporarytechnologies.…

Buch. Condizione: Neu. Neuware - The book summarizes present scientific knowledge in plant physiology with regards to plant production. The authors, mainly professors of plant physiology at agricultural universities in Czechoslovakia, present the individual fields of plant physiology with regard to the demands of agricultural practice and education of students and doctorani at these universities.The first chapters discuss metabolism ie. photosynthesis, respiration, mineral and heterotrophic nutrition, and water regime of plants. What follows is a discussion of the physiology of plant growth, development and movements, and finally resistance of plants against unfavourable abiotic and biotic effects.The book shows how to increase the yield of crops by manipulating photosynthesis and also studies the possible flow of photosynthetic products to the commercially valuable parts of the biomass. Rational plant production, however, cannot do without knowledge of plant nutrition and water regime as a theoretical basis for fertilization and irrigation. The reader will find this knowledge detailed as well as information about the ecological and physiological principles of the resistance of plants against drought, frost, heat, diseases and other unfavourable effects.…
