On the interconnection of message passing systems
Elsevier (2008)One of the most important abstractions for designing distributed programs is the broadcast facility. In this paper, we study the interconnection of distributed message passing systems. We have shown that totally ordered ... -
A parametrized algorithm that implements sequential, causal, and cache memory consistencies
Elsevier (2008)In this paper, we present an algorithm that can be used to implement sequential, causal, or cache consistency in distributed shared memory (DSM) systems. For this purpose it includes a parameter that allows us to choose ...

Log-polar mapping template design: From task-level requirements to geometry parameters
Elsevier (2008)The best parameters defining the geometry of a visual sensor generally depend on the particular visual task the sensor is intended to be used in. However, translating task requirements directly into low-level geometric ...

Contextualizing data warehouses with documents
Elsevier (2008)Current data warehouse and OLAP technologies are applied to analyze the structured data that companies store in databases. The context that helps to understand data over time is usually described separately in text-rich ...

Analysis and placement of storage capacity in large distributed video servers
Elsevier (2008)In this paper, we study how to distribute storage capacity along a hierarchical system with cache-servers located at each node. This system is intended to deliver stored video streams in a video-on-demand way, ensuring ...

Impact of the -1438G>A polymorphism in the serotonin 2A receptor gene on anthropometric profile and obesity risk: A case-control study in a Spanish Mediterranean population
(2008)Research into the genetic factors that regulate food intake is arousing great interest. The polymorphism -1438G>A in the serotonin 2A receptor or 5-hydroxytriptamine (5-HT) type 2A receptor (5-HTR2A) gene has been ...

Stability bounds in networks with dynamic link capacities
Elsevier (2008)We address the problem of stability in networks where the link capacities can change dynamically. We show that every network running a greedy scheduling policy is universally stable at any injection rate r < 1 / (C d), ...

Evaluation of color prediction models in the decoration of ceramic tiles
The Ceramic Society of Japan (2008) -
Integrating data warehouses with web data : a survey
IEEE Computer Society (2008)This paper surveys the most relevant research on combining Data Warehouse (DW) and Web data. It studies the XML technologies that are currently being used to integrate, store, query, and retrieve Web data and their ...

Assessment of disease named entity recognition on a corupus of annotated sentences
BioMed Central (2008)Background: In recent years, the recognition of semantic types from the biomedical scientific literature has been focused on named entities like protein and gene names (PGNs) and gene ontology terms (GO terms). Other ...

Influence of color spaces over texture characterization
Instituto Politécnico Nacional (Mèxic). Centro de Investigación en Computación (2008)Images are generally represented in the RGB color space. This is the model commonly used for most cameras and for displaying on computer screens. Nevertheless, the representation of color images using this color space has ...

Dante: A Self-Adapting Peer-to-Peer System
Springer Verlag (2008)In this paper we introduce DANTE, an unstructured P2P system in which the topology of the underlying overlay network can be dynamically adapted to the system conditions. Such an adaption is performed by the peers in an ...

The Role of Face Parts in Gender Recognition
Springer Verlag (2008)This paper evaluates the discriminant capabilities of face parts in gender recognition. Given the image of a face, a number of subimages containing the eyes, nose, mouth, chin, right eye, internal face (eyes, nose, ...
-
A Tool for the Creation and management of level-of-detail models for 3D applications
World Scientific and Engineering Academy and Society (WSEAS) (2008)Real-time visualization of 3D scenes is a very important feature of many computer graphics solutions. Current environments require complex scenes which contain an increasing number of objects composed of thousands or ...
-
Safe and Economic Re-Use of Ontologies: A Logic-Based Methodology and Tool Support
Springer Verlag (2008)Driven by application requirements and using well-understood theoretical results, we describe a novel methodology and a tool for modular ontology design. We support the user in the safe use of imported symbols and in the ...
-
On the Complementarity of Face Parts for Gender Recognition
Springer Verlag (2008)This paper evaluates the expected complementarity between the most prominent parts of the face for the gender recognition task. Given the image of a face, five important parts (right and left eyes, nose, mouth and chin) ...
