These Transactions publish archival papers in the broad area of Petri nets and other models of concurrency, ranging from theoretical work to tool support and industrial applications. ToPNoC issues are published as LNCS volumes, and hence are widely distributed and indexed. This Journal has its own Editorial Board which selects papers based on a rigorous two-stage refereeing process. ToPNoC contains: - Revised versions of a selection of the best papers from workshops and tutorials at the annual Petri net conferences - Special sections/issues within particular subareas (similar to those published in the Advances in Petri Nets series) - Other papers invited for publication in ToPNoC - Papers submitted directly to ToPNoC by their authors The 7th volume of ToPNoC contains revised material from the 5th International Summer School "Advanced Course on Petri Nets", held in September 2010 in Rostock, Germany. The nine papers cover a diverse range of topics including modeling, verification, partial order semantics, and synthesis of Petri nets. In compliance with their origin as course material, the papers are written in survey or tutorial style and give a comprehensive overview of the state of the art in their respective areas.

This book constitutes the refereed proceedings of the 9th International Conference on Business Process Management, BPM 2011, held in Clermont-Ferrand, France, in August/September 2011. The volume contains 22 revised full research papers carefully reviewed and selected from 157 submissions, as well as 5 industrial track papers and abstracts of three invited talkes. The papers address innovative research of highest quality from computer science, management information science, service-oriented computing, and technology management.

This volumecontainstheproceedingsofthe 5thInternationalWorkshoponWeb Services and Formal Methods (WS-FM 2008) held during September 4-5, 2008 in Milan, Italy, co-located with the 6th International Conference on Business Process Management (BPM 2008). Previous editions of the workshop were held in Pisa, Italy (WS-FM 2004), Versailles, France(WS-FM 2005), Vienna, Austria (WS-FM 2006) and Brisbane, Australia (WS-FM 2007). The aim of the workshop series is to bring together researchers working on web servicesand formal methods in order to catalyzefruitful collaboration. Web service (WS) technology provides standard mechanisms and protocols for - scribing, locatingandinvokingservicesavailableallovertheweb.

However, researchisstillneededto moveWStechnologyfrom skilled handcrafting to well-engineeredpractice. Formal methods can play a f- damental role in the shaping of such innovations. For instance, they can help us de?ne unambiguous semantics for the languages and protocols that underpin existing WS infrastructures, and provide a basis for checking the conformance and compliance of bundled services. The WS-FM series has a strong tradition of attracting submissions on formal approaches to enterprise systems modeling in general, and business processmodeling in particular. Potentially, this couldhave a signi?cant impact on the on-going standardization e?orts for WS technology. The main topics of the workshop include: formal approaches to servi- orientedanalysisanddesign, to enterprisemodeling and business processmod- ing; WS coordination and transactions frameworks; formal comparison of di?- ent models proposed for WS protocols and standards; types and logics for WS; goal-drivenandsemantics-baseddiscoveryandcompositionofWS;model-driven development, testing, and analysis of WS; security, performance and quality of services; innovative application scenari

This volume consists of the proceedings of the 30th International Conference on Applications and Theory of Petri Nets and Other Models of Concurrency (PETRI NETS 2009). The Petri Net conferences serve as annual meeting places to discuss the progress in the ?eld of Petri nets and related models of conc- rency. They provide a forum for researchers to present and discuss both app- cations and theoretical developments in this area. Novel tools and substantial enhancements to existing tools can also be presented. The satellite program of the conference comprised four workshops and seven tutorials. This year, the conference was co-located with the 20th IEEE/IFIP International Symposium on Rapid System Prototyping (RSP 2009). The two conferences shared ?ve - vited speakers. Detailed information about PETRI NETS 2009 can be found at http: //petrinets2009. lip6. fr/. The PETRI NETS 2009 conference was organized by Universit e Pierre & 1 Marie Curie as a part of MeFoSyLoMa, gathering research teams from numer- ous universities in Ile-de-France: CNAM, ENS de Cachan, Universit e Evry-V- d'Essone, Universit e Paris-Dauphine, Universit e Paris 12, Universit e Paris 13, and Telecom Paris-Tech. It took place in Paris, France, during June 22-26,2009. We would like to express our deep thanks to the Organizing Committee, chaired by Fabrice Kordon, for the time and e?ort invested in the conference and for all the help with local organization."

Das Lehrbuch befasst sich mit dem prazisen Denken, einer Schlusselkompetenz im Studium der Informatik. Es bildet die Vorstufe fur das Verstandnis der logischen Grundfunktionen der Informatik. Das Erlernen der mathematischen Logik ist ein wesentlicher Bestandteil des Grundstudiums, da das logische Denken in der Informatik auf den gleichen Regeln und Techniken basiert wie in der Mathematik. Der Autor fuhrt umfassend in die Aussagenlogik ein und erklart unter anderem die Bedeutungen von logischer AEquivalenz, Implikation und Induktion fur diesen Fachbereich. Daruber hinaus definiert er den Beweis aus Sicht der Mathematik und stellt grundlegende Beweisstrategien vor, die im Studium benoetigt werden. Mit den in diesem Lehrbuch vorgestellten Techniken des prazisen Denkens erwerben die Studenten die Fahigkeit, Begriffe punktgenau zu definieren, Aussagen trennscharf zu formulieren und ihre Richtigkeit angemessen zu begrunden. Viele praxisnahe Aufgaben und Loesungshinweise innerhalb der Kapitel erleichtern die UEberprufung und Vertiefung des Lernstoffs. Der Autor richtet sich vornehmlich an Bachelorstudenten der ersten Semester. Sie finden in diesem Werk eine optimale Vorbereitung auf die Logik-Seminare ihres Informatikstudiums. Die vermittelten Kompetenzen verbessern dabei nicht nur das Verstandnis im Informatik-Studium, sondern sind ebenso fur das spatere Berufsleben von grosser Bedeutung. Daruber hinaus erhalten auch interessierte Laien mit diesem Buch einen interessanten Einblick in die Welt der Informatik und Mathematik und lernen, dass die Fahigkeit zu prazisem Denken auch jenseits dieser Fachbereiche hilfreich sein kann.
