To select the most suitable simulation algorithm for a given task is often difficult. This is due to intricate interactions between model features, implementation details, and runtime environment, which may strongly affect the overall performance. An automated selection of simulation algorithms supports users in setting up simulation experiments without demanding expert knowledge on simulation. Roland Ewald analyzes and discusses existing approaches to solve the algorithm selection problem in the context of simulation. He introduces a framework for automatic simulation algorithm selection and describes its integration into the open-source modelling and simulation framework James II. Its selection mechanisms are able to cope with three situations: no prior knowledge is available, the impact of problem features on simulator performance is unknown, and a relationship between problem features and algorithm performance can be established empirically. The author concludes with an experimental evaluation of the developed methods.
Geschäftsmodelle in der digitalen Ökonomie, die darauf angelegt sind, Gewinne aus der Nutzung von Daten zu erzielen, stellen die herrschenden Regeln der Gewinnbesteuerung vor besondere und neuartige Herausforderungen. Das fängt bereits bei der rechtlichen Zuordnung der Daten an, die wiederum für die Einordnung als steuerbilanzrechtliches Wirtschaftsgut von Bedeutung ist. Im internationalen Kontext ist entscheidend, wo die Wertschöpfung zu verorten ist und welchem Staat das Besteuerungsrecht deshalb zusteht. Hier setzt die Arbeit von Stephan Kristl an, indem der Datenfluss im Automobilkonzern steuerlich gewürdigt wird.

This book constitutes the refereed proceedings of the 6th International Conference on Computational Methods in Systems Biology, CMSB 2008, held in Rostock, Germany, in September 2008. The 21 revised full papers presented together with the summaries of 5 invited papers were carefully reviewed and selected from more than 60 submissions. The papers cover theoretical or applied contributions that are motivated by a biological question focusing on modeling approaches, including process algebra, simulation approaches, analysis methods, in particular model checking and flux analysis, and case studies.
Bde. 16, 18, 21, and 28 each contain section "Verlagsveränderüngen im deutschen Buchhandel."
