چکیده
Empirical studies of an abstract semantic model, augmented transition network (ATN), with Object Composition Petri Net (OCPN) to model multimedia presentations are performed in this paper. An ATN consists of a set of states and directed arcs and uses a regular expression as its input. The advantages to use a regular expression are its simplicity and ease of modiication. Simulation experiments to compare ATN and OCPN are performed in this paper. The results show that ATN requires fewer nodes and arcs to represent a multimedia presentation than OCPN does. These results indicate ATN handles on-line multime-dia presentations more eecient and requires less precious main memory space.

A Context-aware Architecture for Mental Model Sharing through Semantic Movement in Intelligent Agents
Recent studies in multi-agent systems are paying increasingly more attention to the paradigm of designing intelligent agents with human inspired concepts. One of the main cognitive concepts driving the core of many recent approaches in multi agent systems is shared mental models. In this paper, we propose an architecture for sharing mental models based on a new concept called semantic movement....

متن کاملDeveloping a BIM-based Spatial Ontology for Semantic Querying of 3D Property Information
With the growing dominance of complex and multi-level urban structures, current cadastral systems, which are often developed based on 2D representations, are not capable of providing unambiguous spatial information about urban properties. Therefore, the concept of 3D cadastre is proposed to support 3D digital representation of land and properties and facilitate the communication of legal owners...
متن کاملInvestigation and Statistical comparison of the soil empirical desalinization models for salin-sodic soils (Case study: Khuzestan province)
Accumulation of soluble salts in arid areas which are similar to most regions of Iran is inevitable in soil surface and profile because of low precipitation and high evaporation. High concentration of soluble salts in soil profile caused severe problems for root water uptake thus plant growth stopped. Reducing soil salinity to optimized content by leaching and avoiding soil pounding must be con...
