Buch. Condizione: Neu. Neuware - This book familiarizes both popular and fundamental notions and techniques from the theory of non-normed topological algebras with involution, demonstrating with examples and basic results the necessity of this perspective. The main body of the book is focussed on the Hilbert-space (bounded) representation theory of topological \*-algebras and their topological tensor products, since in our physical world, apart from the majority of the existing unbounded operators, we often meet operators that are forced to be bounded, like in the case of symmetric \*-algebras. So, one gets an account of how things behave, when the mathematical structures are far from being algebras endowed with a complete or non-complete algebra norm. In problems related with mathematical physics, such instances are, indeed, quite common.

Buch. Condizione: Neu. Neuware - At present we are looking at increased life expectancies and prolonged periods of employment. The aged workforce as a natural result of this phenomenon presents society with great challenges.

Buch. Condizione: Neu. Neuware - Capillary Electrophoresis (CE) is a powerful analytical technique used to separate compounds and is increasingly being used in routine analytical laboratories. Analysis and Detection by Capillary Electrophoresis presents developments enabling the enhancement of the detection sensitivity in CE, including the different strategies used to achieve sensitivity requirements. It describes techniques allowing sample preconcentration and sensitive continuous detection systems and looks at recent developments such as chiral analysis in CE and electrochemical detection in microchips. UV-Vis absorbance detection, as the most widely used detection system in CE, is also presented. Analysis and Detection by Capillary Electrophoresis delves into the practical approaches used in the field and will greatly benefit analytical chemists, as well as students, teachers, technical analysts, scientists and researchers involved in capillary electrophoresis.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -It has widely been recognized that submodular functions play essential roles in efficiently solvable combinatorial optimization problems. Since the publication of the 1st edition of this book fifteen years ago, submodular functions have been showing further increasing importance in optimization, combinatorics, discrete mathematics, algorithmic computer science, and algorithmic economics, and there have been made remarkable developments of theory and algorithms in submodular functions. The 2nd edition of the book supplements the 1st edition with a lot of remarks and with new two chapters: 'Submodular Function Minimization' and 'Discrete Convex Analysis.' The present 2nd edition is still a unique book on submodular functions, which is essential to students and researchers interested in combinatorial optimization, discrete mathematics, and discrete algorithms in the fields of mathematics, operations research, computer science, and economics. 410 pp. Englisch.
