Analytical System Dynamics
"Analytical System Dynamics: Modeling and Simulation" combines results from analytical mechanics and system dynamics to develop an approach to modeling constrained multidiscipline dynamic systems. This combination yields a modeling technique based on the energy method of Lagrange, which in turn, results in a set of differential-algebraic equations that are suitable for numerical integration. Using the modeling approach presented in this book enables one to model and simulate systems as diverse as a six-link, closed-loop mechanism or a transistor power amplifier.
Nonlinear Approaches in Engineering Applications
Nonlinear Approaches in Engineering Applications focuses on nonlinear phenomena that are common in the engineering field. The nonlinear approaches described in this book provide a sound theoretical base and practical tools to design and analyze engineering systems with high efficiency and accuracy and with less energy and downtime. Presented here are nonlinear approaches in areas such as dynamic systems, optimal control and approaches in nonlinear dynamics and acoustics. Coverage encompasses a wide range of applications and fields including mathematical modeling and nonlinear behavior as applied to microresonators, nanotechnologies, nonlinear behavior in soil erosion,nonlinear population dynamics, and optimization in reducing vibration and noise as well as vibration in triple-walled carbon nanotubes.
Principles of Analytical System Dynamics
A novel approach to analytical mechanics, using differential-algebraic equations, which, unlike the usual approach via ordinary differential equations, provides a direct connection to numerical methods and avoids the cumbersome graphical methods that are often needed in analysing systems. Using energy as a unifying concept and systems theory as a unifying theme, the book addresses the foundations of such disciplines as mechatronics, concurrent engineering, and systems integration, considering only discrete systems. Readers are expected to be familiar with the fundamentals of engineering mechanics, but no detailed knowledge of analytical mechanics, system dynamics, or variational calculus is required. The treatment is thus accessible to advanced undergraduates, and the interdisciplinary approach should be of interest not only to academic engineers and physicists, but also to practising engineers and applied mathematicians.

Sprache in der Klasse
In dieser Arbeit wird eine Primarschulklasse in einer zweisprachigen Schweizer Stadt untersucht. Die Schulklasse zeichnet sich durch besonders heterogene muttersprachliche Verhältnisse aus. Der schweizerdeutsche Klassendialekt wird mittels zahlreicher dialektologischer Variablen beschrieben, und es zeigt sich, daß im Zusammenspiel von sozialer Dynamik innerhalb der Klasse und innerlinguistischen Bedingungen rasch eine recht hohe sprachliche Konformität entsteht. Über einen soziographischen Zugang wird die Klassenstruktur beschrieben, und es zeigt sich ein starker Zusammenhang zwischen den linguistischen und sozialpsychologischen Datenreihen. Die soziale Netzstruktur innerhalb der Klasse ...
