The book collects many techniques that are helpul in obtaining regularity results for solutions of nonlinear systems of partial differential equations. They are then applied in various cases to provide useful examples and relevant results, particularly in fields like fluid mechanics, solid mechanics, semiconductor theory, or game theory.In general, these techniques are scattered in the journal literature and developed in the strict context of a given model. In the book, they are presented independently of specific models, so that the main ideas are explained, while remaining applicable to various situations. Such a presentation will facilitate application and implementation by researchers, as well as teaching to students.

This volume summarizes the results of a priority program launched by Deutsche Forschungsgemeinschaft (DFG) called KONDISK-Dynamics and Control of Systems with Mixed Continuous and Discrete Dynamics. The program was motivated by the need for a more comprehensive approach to hybrid systems both in the computer science and the control engineering communities. Technical systems nowadays are composed of physical components with mostly continuous dynamics and computerized control systems where the reaction to discrete events plays a major role, implemented in Programmable Logic Controllers (PLCs), Distributed Control Systems (DCSs) or real-time computer systems. Several practical examples of systems with mixed continuous-discrete dynamics are presented, such as a conveyor belt, an annealing furnace, a membranous filtration process, a titration plant, a diesel engine, robotic arms, a chemical reactor, tank systems, or an aircraft elevator system.

Dem anhaltenden Globalisierungsdruck sind die in Europa meist einzelbetrieblich organisierten Hotels kaum noch gewachsen. Um im internationalen Verdrangungswettbewerb bestehen zu konnen, muss die europaische Hotellerie ihren potenziellen Kunden einen Mehrwert bieten, den diese von der Markenhotellerie nicht erhalten. Der Autor zeigt Moglichkeiten auf, wie es der europaischen Individualhotellerie gelingen kann, sich durch den Aufbau internationaler Dienstleistungskompetenzen erfolgreich zu behaupten.

When companies decide upon a strategy to achieve and sustain growth, they can choose between different options to reach this goal. If external growth is chosen, alliances and acquisitions are typically considered alternative governance structures that involve cooperative efforts on the inter-organizational level. Despite this similarity, each of the two governance types has its own strengths and weaknesses: alliances are based on contracts and offer the firm a substantial level of flexibility while acquisitions are ownership-based and imply a higher degree of commitment but also control. In the course of the governance decision, tradeoffs have to be made between flexibility and control. The challenge managers have to decide, which of the two governance modes suits a specific situation best and will achieve superior results for the company. Prior research shows that a company's history in inter-organizational governance influences its future governance choices. Firms that have cooperated in an alliance in the past make different governance choices than firms who lack this experience. In general, companies tend to choose governance modes they are already familiar with for future transactions. In addition, whether the partner firms know each other and have worked together before also influences the choice between alliances and acquisitions. This book lays its focus on situations, where companies have allied in the past and are now deciding upon the appropriate governance form for yet another cooperation. Situations where no alliance experience exists and governance choices other than alliances and acquisitions are not considered here. For academics as well as practitioners, it is then of major interest to identify exactly how knowing the target firm from past alliances affects the decision between alliances and acquisitions. However, prior research on the influence of partner-specific alliance experience on governance choice yields mixed results. While it has been pr
