Texture is an innate property of all surfaces referring to visual patterns not resulting from the presence of a single color or intensity. Albeit being intuitively obvious, texture lacks a precise definition. Humans often distinguish textures with properties like periodicity, directionality, granularity, and randomness. Because of the importance and usefulness of texture information, various te...

Parallel Programming relies on the coordination of computing resources, so that they simultaneously work towards a common objective. Achieving this requires extra effort from the software designer, because of the increased complexity involved. Furthermore, as Parallel Programming is considered a means to improve performance, the software designer has to consider sophisticated and cost-effective...

The need for interaction between knowledge -based systems (KBS) and the user has increased, mainly, to enhance the acceptability of the reasoning process and of the solutions proposed by the KBS. Based on this need, we p ropose Design Patterns to facilitate the development of interaction characteristics in KBSs. Particularly, we define a design pattern to provide explanation, since we consider ...

processing applications. It rst contrasts XML with more traditional approaches to language processing. Second, the main processing paradigms for XML are brie y discussed, with a number of example applications. Several forces that in uence how XML is processed or generated are identi ed and discussed. Then a design pattern is presented that resolves these forces in a particular way. The main obj...

Current models for software components have made component-based software engineering practical. However, these models are limited in the sense that their support for the characterization/specification of design components primarily deals with syntactic issues. To avoid mismatch and misuse of components, more comprehensive specification of software components is required, In this paper, we pres...

In this paper we present a novel approach to personal photo album management allowing the end user to efficiently access the collection without any need for tedious manual annotation or indexing of the photos. The proposed work exploits methods and technology from the field of computer vision and pattern recognition for face detection, face representation and image annotation to automatically c...

In this study,we analyze the network effect in amodel of a personal communicationmarket, by using amulti-agent based simulation approach.We introduce into the simulationmodel complex network structures as the interaction patterns of agents. With complex network models,we investigate the dynamics of amarket inwhich twoproviders are competing.We also examine the structure of networks that affect ...

Existing container-based development strategies provide solutions to the problem of encapsulating cross-cutting concerns in component-based software systems. These approaches fall short, however, in enabling tractable reasoning. To extend existing work in reasoning about parameterized components to container-based approaches, we view containers as parameterized components. We present a model of...

We present a generic architecture for content-based retrieval of images, which can be extended to the requirements of large distributed and heterogeneous collections. The system is modeled as a multi-agent system where an autonomous search agent encapsulates an independent image retrieval algorihtms. An optimal team of agents is dynamically selected for every retrieval problem. A flexible proto...

The problematic issues in the development of manufacturing software systems are related to the various nature of manufacturing systems, which are wide, dynamic and complex. The purpose of this paper is to provide a solution by using framework-based software engineering to solve these problems. Framework-based software engineering is the idea of constructing software systems based on the integra...
