We propose a multilayered multiagent simulator that can simulate traffic in any urban environment on earth, subject to specific weather conditions. We adopt an agent-based approach for the behaviors of the vehicles and the drivers. We additionally propose a behavioral model to realistically emulate the driving behaviors of humans.

A systematic procedure for sensitivity analysis of a case study in the area of air pollution modeling has been performed. Contemporary mathematical models should include a large set of chemical and photochemical reactions to be established as a reliable simulation tool. The Unified Danish Eulerian Model is in the focus of our investigation as one of the most advanced large-scale mathematical mo...

We report on a combination of system theoretic simulation modeling methodology with the JavaBeans component model as a basis for a component-based simulation framework. While system theory formalisms can serve as formal, mathematical foundations for modular, hierarchical modeling and simulation, the JavaBeans component model provides the appropriate implementation base. The result of the synerg...

A growing and important area of Model-Based Development (MBD) is model evolution. Despite this, very little research on the evolution of Simulink models has been conducted. This is in contrast to the notable amount of research on UML models, which di↵er significantly from Simulink. Code clones and their evolution across system versions have been used to learn about source-code evolution. We pos...

The concept of component-based development (CBD) is widely practiced in software (SW) development. CBD is based on reuse of the existing components with the new ones. The objective of this paper is to propose a novel process model for CBD. Importance of repository has also been discussed. A survey has been conducted to evaluate the proposed model. The results of the survey show that proposed pr...

The adoption of new technology depends on various factors, such as the type of technology, the context or culture in which the technology is introduced, and the individual decisions by people within that culture. This work presents an approach that uses an agent-based model to encompass the detailed behavior of individuals and their immediate network of relationships, as well as an influence-ba...

This paper reviews the nature of detailed design process and discusses the implementation of a knowledgebased system founded on a protocol analysis study. The main objective is to discuss the features of a knowledgebased modeling approach, NoDes (kNOwledge based modeling for detailed DESign process). This approach was first used for the development of the WIND, which is an interactive Knowledge...

The creation of 3D computer models is an essential task for many applications in science, engineering and arts and is frequently performed by untrained users. In many cases speed and simplicity of the modeling process is more important than matching the geometry of the modeled object exactly. Sketch-based modeling has been suggested as an important tool for such applications. In this paper we e...

In this paper, we introduce surface plenoptic function (SPF) as a tool for the sampling analysis of image-based rendering (IBR). SPF is a plenoptic function defined on the object surface. It can be mapped onto the normal IBR representation via a coordinate transform. By assuming some properties of the SPF, we can provide insightful analysis on the sampling of the IBR representation, for both un...

We present an interface for 3D object manipulation in which standard transformation tools are replaced with transient 3D widgets invoked by sketching context-dependent strokes. The widgets are automatically aligned to axes and planes determined by the user’s stroke. Sketched pivot-points further expand the interaction vocabulary. Using gestural commands, these basic elements can be assembled in...
