Matching Nondeterministic Services with Operating Guidelines
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, ...
Modeling Event-driven Time Series with Generalized Hidden Semi-Markov Models
This report introduces a new model for event-driven temporal sequence processing: Generalized Hidden Semi-Markov Models (GHSMMs). GHSMMs are an extension of hidden Markov models to continuous time that builds on turning ...
Distributed Abstract State Machines and Their Expressive Power
Gurevich’s sequential Abstract State Machines (ASMs) are taken as a basis for the construction of distributed ASMs as sets of sequential ASMs. A theorem on the expressive power of distributed ASM is proven in analogy to ...
Daubechies Versus Biorthogonal Wavelets for Moving Object Detection in Traffic Monitoring Systems
Moving object detection is a fundamental task for a variety of traffic applications. In this paper the Daubechies and biorthogonal wavelet families are exploited for extracting the relevant movement information in moving ...
