Several techniques are proposed to retrieve the most relevant HTML documents to user query. Among these techniques is the genetic algorithm which iteratively creates several generations using selection, crossover and mutation before producing the final result. In this paper, a new hybrid crossover technique is proposed to enhance the quality of the retrieved results. This technique is applied to HTML documents and evaluated using recall, precision and recallprecision measures. Its performance is compared to three well known techniques of crossover. The results show high improvement in the quality of the retrieved documents in terms of these measures.

The Electrocardiogram (ECG) is a diagnostic tool that measures and records the electrical activity of the heart. Interpretation of the ECG signal allows diagnosis of a wide range of heart conditions. These conditions can vary from minor to life threatening. In this paper real ECG records provided by the MIT-BIH Arrhythmia Database are used to build an efficient mechanism for detecting abnormalities in the ECG records. Prior to the detection, selected filters are used to eliminate any interference while maintaining the useful information within the signal. Detection of Heartbeat-related abnormalities of other heart diseases such as AV blockage and Ventricular Fibrillation is implemented. Results of ECG signal preprocessing and abnormality detection demonstrate the suitability of the selected filtering techniques and the efficiency of the detection mechanisms.

BNGA is a computer programs production that employs the engine of GA as a base for building its programs. BNGAs' genotypes (solutions) have a list of integers that are used to develop the phenotypes (programs). These phenotypes are developed by using the grammatical syntax of the programming language. In this paper, BNGA is investigated and designed to study the symbolic regression and classification problems. Detailed analysis of these problems are examined and the results were clearly in favor of BNGA. All results were compared experimentally with other suggested techniques. Through these experiments, BNGA proved as a competitive approach that can be applied in practice to solve the problems of both computer science and engineering. © 2012 IEEE.

In this paper, we describe the semantic annotation process for developing a semantic web application to a university's library. Semantic annotation is the step that adds the effectiveness and reality to the semantic web application. It is annotating the documents published and distributed throughout the Web. The semantic annotation in this paper concerns about the research papers of the university's faculty. Semantic annotation is nothing but tagging the instances data of ontology already created with classes then map in to the related ontology classes. Here we are going to use two tools for building annotation library, these tools are: OntoMat and OntoStudio. © 2012 NSP.

Objective: To determine the incidence and trends of gestational diabetes mellitus (GDM) in Bahrain from 2002 to 2010, and to investigate 2 possible risk factors within the affected population. Methods: In a retrospective survey, data on maternal body weight and age were collected from women who gave birth in government maternity units in Bahrain and who were screened for GDM during pregnancy using the 2-step approach and criteria of the US Expert Committee on the diagnosis and classification of diabetes. Results: Among 49 552 pregnant women, 4982 (10.1%) were diagnosed with gestational diabetes. The Cox-Stuart test for trend analysis suggested that there was an increase in the incidence of gestational diabetes from 7.2% in 2002 to 12.5% in 2010 (P < 0.01). For the period 2006-2010, maternal age, and weight at onset of pregnancy and at time of delivery were positively associated with risk of GDM with an odds ratio (95% confidence interval) of 1.094 (1.081-1.107), 1.081 (1.001-1.104), and 1.027 (1.013-1.040), respectively. Conclusion: A combination of increasing maternal weight, maternal age, and incidence of GDM among women in Bahrain indicates a significant future burden on health services. © 2011 International Federation of Gynecology and Obstetrics.
