Buch. Condizione: Neu. Neuware - This volume deals with first and second order complex equations of hyperbolic and mixed types. Various general boundary value problems for linear and quasilinear complex equations are investigated in detail. To obtain results for complex equations of mixed types, some discontinuous boundary value problems for elliptic complex equations are discussed. Mixed complex equations are included in the quasilinear case, and the text considers both boundary value conditions in the general oblique derivative case and multiply connected domains. Complex analytical methods are used to investigate various problems as well. In particular, hyperbolic numbers and hyperbolic complex functions are introduced to handle hyperbolic complex equations. Researchers and graduate students in mathematical analysis will find this text indispensable.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Human factors considerations are increasingly being incorporated into the product design process. Users are seen more as being important factors in the overall look and usability of products than just as passive users. We are now treated as cognitive and physical components of the person/product system. The author, who is one of the leading lights in the field of cognitive ergonomics, looks at approaches that assume that if a task can be accomplished with a reasonable degree of efficiency and within acceptable levels of comfort, then the product can be seen as fitting to the user. In this book it is argued that in practice these approaches can be dehumanizing. People are more than merely physical and cognitive processors. They have hopes, fears, dreams, values and aspirations, indeed these are the very things that make us human.Designing Pleasurable Products looks both at and beyond usability, considering how products can appeal to use holistically, leading to products that are a joy to own. 226 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The theory of optimal control systems has grown and flourished since the 1960's. Many texts, written on varying levels of sophistication, have been published on the subject. Yet even those purportedly designed for beginners in the field are often riddled with complex theorems, and many treatments fail to include topics that are essential to a thorough grounding in the various aspects of and approaches to optimal control.Optimal Control Systems provides a comprehensive but accessible treatment of the subject with just the right degree of mathematical rigor to be complete but practical. It provides a solid bridge between 'traditional' optimization using the calculus of variations and what is called 'modern' optimal control. It also treats both continuous-time and discrete-time optimal control systems, giving students a firm grasp on both methods. Among this book's most outstanding features is a summary table that accompanies each topic or problem and includes a statement of the problem with a step-by-step solution. Students will also gain valuable experience in using industry-standard MATLAB and SIMULINK software, including the Control System and Symbolic Math Toolboxes.Diverse applications across fields from power engineering to medicine make a foundation in optimal control systems an essential part of an engineer's background. This clear, streamlined presentation is ideal for a graduate level course on control systems and as a quick reference for working engineers. 460 pp. Englisch.
