Immersive 3D environments are used in virtual product creation to support designers during the design process. Various approaches exist that focus on immersive sketching techniques, as sketching is a prominent technique in the early phases of product design. This thesis addresses the question whether automatic shape creation from sketched input strokes in an immersive 3D environment supports th...

We consider the problem of incremental cycle analysis for dataflow models in the Embedded Systems Modeling Language (ESMoL). We give a general form of a cycle enumeration algorithm that makes use of graph hierarchy to improve analysis efficiency. Our framework also stores simple connectivity information in the model to accelerate future cycle analyses when additional components are added or mod...

Image-based rendering is one of the hottest new areas in computer graphics. Instead of using 3D modeling and painting tools to construct graphics models by hand, IBR uses real-world imagery to rapidly create photorealistic shape and appearance models. However, IBR results to date have mostly been restricted to static objects and scenes. Videobased rendering brings the same kind of realism to co...

Constructing complex software systems by integrating different software components is a promising and challenging approach. With the functionality of software components given by models it is possible to ensure consistency of such models before implementation in order to successfully build the system. Models consisting of different submodels, the absence of an overall formal semantics and the n...

Agent researchers are still trying to determine useful ways of representing agents and agent-based systems. So this paper presents a proposal for a Systematic Approach for Agent Design by using Unified Modeling Language (UML) diagram. In this paper we illustrate notions for the behavior of an agent using and extending UML class diagrams. Focus on representing the agent migration from take reque...

We present an implicit modeling system as a tool for creating a wide range of aesthetic models. Because of their ability to form blends and produce both organic shapes as well as man-made objects, implicit surfaces are a good medium for artists seeking new ways to experiment with 3D modeling. Implicit models can be created using our sketch-based modeling tool Shapeshop and also by using a proce...

Recent work within the CBR community has studied more systematic means of interrelating different types of domain knowledge, tasks, and methods for building and maintaining CBR systems. This paper reviews work from the knowledge acquisition community, targeted at methodologies and tools for analysis, modeling, and maintenance of knowledge components. It is argued that the knowledge level is the...

Designing components and composing them into an architecture inherently involves describing their behavior. The classical software engineering approach to specifying requirements for large-scale components is to start with use cases. However, employing use cases to component architectures triggers the need of (i) assembling the behavior specified by several use cases, (ii) composing the behavio...

Repast is a widely used, free, and open-source agent-based modeling and simulation toolkit. Three Repast platforms are currently available, each of which has the same core features but a different environment for these features. Repast Simphony (Repast S) extends the Repast portfolio by offering a new approach to simulation development and execution. This tutorial presents a simple “boids” styl...

This paper suggests a component-based software development framework for 3rd party logistics (3PL) business. This framework integrates two engineering methodologies in order to identify the most reusable software components that can be used in several types of 3PL business models. UML (Unified Modeling Language) is used to design lower-level software components and DEMO (Design and Engineering ...
