Research ArticleOpen accessIn the abstractA Self-Tuning Proportional-Integral-Derivative Controller for an Autonomous Underwater Vehicle, Based On Taguchi MethodM. Santhakumar, T. AsokanProblem statement: Conventional Proportional-Integral-Derivative (PID) controllers exhibit moderately good performance once the PID gains are properly tuned. However, when the dynamic characteristics of the system are time dependent or the operating conditions of the system vary, it is necessary to retune the gains to obtain desired performance. This situation has renewed the interest of researchers and practitioners in PID control. … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Projects in E-Learning Course: A Case of an Information Technology ProjectMohammed Ghaouth Belkasmi, Toumi Bouchentouf, Mostafa Azizi, Abdelhamid BenazziProblem statement: Achieving projects is primordial in the process of teaching in several disciplines, particularly software engineering courses. However, proposing this learning activity in a context of e-learning is not automatically guaranteed by the current platforms, even unsupported by the existing standards for creating educational content. Approach: Through this study, starting from the model developed in the “XESOP-Jaxe” project to … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeature Analysis of Recommender Techniques Employed in the Recommendation EnginesGopinath Ganapathy, P. K. AruneshProblem statement: Recommender Systems (RS) have become a widely researched area as it is extensively used in web usage mining and E-commerce platforms. Approach: There were a number of recommender systems available to suggest the web pages for the web users. Results: A recommender system acted as an intelligent intermediary that automatically generates and predicts information and web pages, which … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 6,698 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving Term Extraction Using Particle Swarm Optimization TechniquesMohammad Syafrullah, Naomie SalimProblem statement: Term extraction is one of the layers in the ontology development process which has the task to extract all the terms contained in the input document automatically. The purpose of this process is to generate list of terms that are relevant to the domain of the input document. In the literature there are many approaches, techniques and algorithms … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,138 accessesView PDFCite
Research ArticleOpen accessIn the abstractMyocardial-Infraction Based on Intelligent TechniquesIbrahim Abdulrab AhmedProblem statement: Heart disease is the leading cause of death in the world. One of the most common types of heart diseases is Myocardial-Infraction. The ability to automatically identify Myocardial-Infraction from cardiac profiles test is important for clinical diagnosis and treatment. Approach: The aim of this study is to see whether the heart is healthy or not, in another words … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,607 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioInfoPhysics Models of Neuronal Signal Processes Based on Theories of Electromagnetic FieldsKang Cheng, Chang H. ZouProblem statement: The aphasia is one of human language and action related brain associative diseases. The mechanisms of the diseases and the brain association are still unclear. In this study, we proposed our models of the neuronal signal processes, in a view of BioInforPhysics, to understand the mechanisms. Approach: Our models are based on today’s solidest Electromagnetic Fields (EMF) theoretic … …Neuroscience International, Vol. 1, Issue 1 · 10 Feb 2010 · 6,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Multi-form Multiple Choice Editor Exam Tool Based on HTML Website and Artificial Intelligence TechniquesA. Rjoub, Y. Eyadat, A. Ghazawi et al.Problem statement: The educators argue that in the post modern world changes in the nature of work, globalization, the information revaluation and today's social challenges will all impact on educational priorities and thus will require a new mode of assessment. Approach: The objectives of this study were to: (1) Present a novel software package tool to create multiple choice and … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Numerical Estimation of Thermal Contact Resistance in Contacting SurfacesM.H. Shojaefard, K. GoudarziFor some manufacturing processes, the heat transfer between the components, the tools and the environment has an effect on tool-life and the accuracy of the formed component. Consequently, the measurement of Thermal Contact Resistance (TCR) is of increasing interest to researchers and industrial engineers participating in the manufacture of high-precision components. A new transient method and measurement apparatus are used … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,451 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploiting Surrounding Text for Retrieving Web ImagesS. A. Noah, A. Azilawati, T. M.T. Sembok, T. W.T.S. MeriamWeb documents contain useful textual information that can be exploited for describing images. Research had been focused on representing images by means of its content (low level) description such as color, shape and texture, little research had been directed to exploiting such textual information. The aim of this research was to systematically exploit the textual content of HTML documents for … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Model Reference Adaptive Controller Based-On Neural-Fuzzy Techniques for Nonlinear Dynamical SystemsHafizah Husain, Marzuki Khalid, Rubiyah YusofThis paper presents a direct neural-fuzzy-based Model Reference Adaptive Controller (MRAC) for nonlinear dynamical systems with unknown parameters. The two-phase learning is implemented to perform structure identification and parameter estimation for the controller. In the first phase, similarity index-based fuzzy c-means clustering technique extracts the fuzzy rules in the premise part for the neural-fuzzy controller. This technique enables the recruitment … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,939 accessesView PDFCite
