In this work we present a discrete event model to design and implement a real time system simulator. This kind of software is useful to verify and evaluate algorithms and models, and to compute performance metrics. The discrete event model…

Multiple ontologies over shared domain has been produced in the geographic ontology-design field for GIS environments. In geneal, each GIS solution has its own data model or application ontology. Ontology model mapping could provide a common language from which several…

The main purpose of this book is to present the contents of an introductory course in databases. In this regard, one can find a number of material validity and recognized different scopes. This work is developed under the guidelines that…

In order to manage projects efficiently, agile methodologies for software development tools that improve production processes have emerged. This paper discusses the adaptation and implementation of the SCRUM methodology in a software development company of the NEA (Northeast Argentina) used…

Reuse-oriented software methodologies have emerged to provide a set of rules or guides for development and evolution of software systems by reusing existing domain engineering artefacts such as requirements, architecture, components, test cases, etc. Domain engineering methods, such as software…

This study proposes the use of abstract software models in order to meet the diversity of embedded platforms. A UML 2.0 Profile for Modeling Application and Platform of Embedded Software (called PROAPES) is proposed. Such profile is intended to generically…

Many refactorings are simple but tedious, which makes them good candidates for automation. Common refactorings include renaming identifiers, moving code between classes or functions, and encapsulating variables. Most integrated development environments (IDEs) – including Eclipse, IntelliJ IDEA, Microsoft Visual Studio,…

In this paper a fully automatic scheme for embedding visually recognizable watermark patterns to video objects is proposed. The architecture consists of 3 main modules. During the first module unsupervised video object extraction is performed, by analyzing stereoscopic pairs of…

Music education should start from an early age. Theories of child development and learning emphasize the importance of manipulating physical objects. Music learning and teaching has traditionally been carried out mainly by visual and auditory activities. With this in mind,…

Based on our experience, in this paper we present the main aspects of two different approaches to implement low cost multi-touch tables: projection based and LCD based. The former uses a video projector to build a feedback image on the…
