Verteilte Geschäftsprozesse nutzen das Internet, um auf heterogenen Rechnerstrukturen Dienste auszubieten. Modellierungstechniken und Implementierungssprachen für solche Dienste werfen im Vergleich mit herkömmlichen Rechnern ...

This paper proposes a strategy for parallel composite event detection in Active database systems (DBS). Up to now, the detection is sequential and totally synchronized, and thus preserves the timely order of events during ...

Interorganizational cooperation is more and more organized by the paradigm of services. The service-oriented architecture (SOA) provides a general framework for service interaction. It describes three roles, service provider, ...

There exist many different Petri net formalisms. In this paper, we present the Petri Net Cube which helps to structure and classify the variety of Petri net formalisms. We show, that three basic aspects are sufficient for ...

We propose and investigate Multi-Channel Extremely Opportunistic Routing (MCExOR) which is a protocol that extends Extremely Opportunistic Routing by utilizing multiple RF channels in multi-hop wireless networks. Large ...

Abstract State Machines (ASM) have been introduced as “a computation model that is more powerful and more universal than standard computation models” by Yuri Gurevich in 1985. Here we provide a bunch of intuitive and ...

The internet today has grown to be more than just being a basis for exchanging information. It steadily becomes a platform for processing business processes. Many companies distribute their service with the help of web ...

For the two-sample location problem we consider a general class of tests, all members of it are based on U-statistics. The asymptotic efficicacies are investigated in detail. We construct an adaptive test where all statistics ...

For the two-sample location and scale problem Lepage (1971) constructed a test that is based on a combination of the Wilcoxon test statistic and the Ansari-Bradley test statistic. We replace both components by arbitrary ...
