This paper describes the usage of descriptive process modeling in the association with simulation for analyzing the dynamic effects of processes. At first a method to build a comprehensive descriptive model is presented, which can build the foundation for the simulation model. Based upon the understanding of the static process, parts of the dynamic model can be modeled can be created. The initi...

In this paper, we report on a study that was performed within the “Semantics of History” project on how descriptions of historical events are realized in different types of text and what the implications are for modeling the event information. We believe that different historical perspectives of writers correspond in some degree with genre distinction and correlate with variation in language us...

The recently developed code FREYA (Fission Reaction Event Yield Algorithm) generates large samples of complete fission events, consisting of two receding product nuclei as well as a number of neutrons and photons, all with complete kinematic information. Thus it is possible to calculate arbitrary correlation observables whose behavior may provide unique insight into the fission process. We firs...

todays, dynamic models are supposed as the most important tools in erosion and sediment phenomenadue to their complexities and existence of many affecting factors. towards, the present study wasconducted in the kojour watershed for daily sediment modeling using daily rainfall, discharge andsediment during 2007 to 2010. the modeling process was carried out all data and the monthly andseasonally ...

In this paper we will present a framework for modeling and management of complex systems. There are various approaches for modeling of these systems. One of the approaches is events driven modeling and management of complex system. Such approach is needed in information systems that provide information in real-time. Most of the existing modeling approaches use only information about type of eve...

With the widespread availability of event-history data, demographers have increasingly eschewed registration-system data in favor of survey data. We propose instead using survey and registration-system data in combination, via a constrained maximum-likelihood framework for demographic hazard modeling. As an application, we combine panel survey data and birth registration data to estimate annual...

This paper deals with the formalization of Unified Modeling language (UML) by means of Petri Nets. In order to improve the semantics of UML dynamic diagrams, we define a new method of embedding UML StateCharts into Interval Timed Petri Nets (ITPN). This method considers all kinds of hierarchical states together with the most of pseudo-states like history ones. Besides consistencies analysis, ti...
