A total of 89 patients with alcoholic cirrhosis and 40 healthy subjects were included in a study to assess the prevalence of intestinal bacterial overgrowth and to analyze its relationship with the severity of liver dysfunction, presence of ascites, and development of spontaneous bacterial peritonitis (SBP). Bacterial overgrowth was measured by means of a(More)
This paper presents an application of diverse soft-computing techniques to adaptive traffic light controls. The proposed methodology consists of two main phases: off-line and on-line. First, clustering techniques and optimization methods are used at the off-line stage to discover the prototypes which characterize the traffic mobility patterns at an(More)
In this work, a concept representation model (FISCRM) has been developed, which is based on two types of fuzzy interrelations between words, synonymy and generality, obtained from a fuzzy dictionary of synonyms [1] and a fuzzy ontology respectively. The model has been put into the metasearcher FISS (Fuzzy Interrelations and Synonymy based Searcher) which is(More)
The quality of class diagrams is critical because it has a great influence on the quality of the object oriented information system (OOIS) which are finally delivered. This fact motivated us to define a set of measures for evaluating the structural complexity (an internal quality attribute) of class diagrams made using the Unified Modeling Language (UML),(More)
Bacterial translocation (BT) has been involved in the pathogenesis of spontaneous bacterial peritonitis (SBP) in experimental cirrhosis. Because malnutrition is a common feature in cirrhosis, the aim of this study was to evaluate the effect of nutrition on BT and SBP. We induced cirrhosis in 44 Sprague-Dawley rats by administration of oral CCl4, and,(More)
This article presents a semantic-based Web retrieval system that is capable of retrieving the Web pages that are conceptually related to the implicit concepts of the query. The concept of “concept” is managed from a fuzzy point of view by means of semantic areas. In this context, the proposed system improves most search engines that are based on matching(More)
Nowadays, the impact of technological developments on improving human activities is becoming more evident. In e-learning, this situation is no different. There are common to use systems that assist the daily activities of students and teachers. Typically, e-learning recommender systems are focused on students; however, teachers can also benefit from these(More)
