Research ArticleOpen accessIn the abstractNumerical Analysis of Pulsatile Blood Flow in a Stented Human Coronary Artery with a Flow DividerVahab Dehlaghi, Mohammad Tafazoli Shadpoor, Siamak NajarianShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Local flow alterations created by a different stents without and with flow divider were studied to compare the hemodynamic effects of Stent design properties on restenosis in stented human coronary artery. Blood pressure and shear stress values were computed in three different … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 6,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent Voice-Based Door Access Control System Using Adaptive-Network-based Fuzzy Inference Systems (ANFIS) for Building SecurityWahyudi, Winda Astuti, Syazilawati MohamedSecure buildings are currently protected from unauthorized access by a variety of devices. Even though there are many kinds of devices to guarantee the system safety such as PIN pads, keys both conventional and electronic, identity cards, cryptographic and dual control procedures, the people voice can also be used. The ability to verify the identity of a speaker by analyzing … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 8,547 accessesView PDFCite
Research ArticleOpen accessIn the abstractApproaches for Categorization of Reusable Software ComponentsParvinder Singh Sandhu, Janpreet Singh, Hardeep SinghReuse repositories manager manages the reusable software components in different categories and needs to find the category of reusable software components. In this paper, we have used different pure and hybrid approaches to find the domain relevancy of the component to a particular domain. Probabilistic Latent Semantic Analysis (PLSA) approach, LSA, Singular Value Decomposition (SVD) technique, LSA Semi-Discrete Matrix Decomposition … …Journal of Computer Science, Vol. 3, Issue 5 · 31 May 2007 · 6,902 accessesView PDFCite
Research ArticleOpen accessIn the abstractResource Leveling Using Petrinet and Memetic ApproachK. Raja, S. KumananThe problem of scheduling activities dynamic for a project, within the available resources and adhering to precedence relationships is NP hard combinatorial. Traditional approaches and their extensions are limited in application for simultaneous scheduling of resources with leveling. Considering the need for improved modeling and scheduling techniques, this paper proposes the use of Petrinet based approach aided by memetic algorithm. … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Complexity Performance Effective Task Scheduling Algorithm for Heterogeneous Computing EnvironmentsE. Ilavarasan, P. ThambiduraiA heterogeneous computing environment is a suite of heterogeneous processors interconnected by high-speed networks, thereby promising high speed processing of computationally intensive applications with diverse computing needs. Scheduling of an application modeled by Directed Acyclic Graph (DAG) is a key issue when aiming at high performance in this kind of environment. The problem is generally addressed in terms of task … …Journal of Computer Science, Vol. 3, Issue 2 · 28 Feb 2007 · 9,663 accessesView PDFCite
Research ArticleOpen accessIn the abstractMaking Sense of Industrial Accidents: The Role of Job SatisfactionSeth A. Gyekye, Simo SalminenThe study examined causality attributions made for workplace accidents and how these attributions may be influenced by job satisfaction. It was part of an extensive exploratory work on causal attributions for industrial accidents in Ghana's work environment. It was carried out in a field setting where the participants were actual accident victims (n=121), co-workers (n=117) and supervisors (n=82) at their … …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractWell-Posedness of Second Order Uniformly Elliptic Boundary Control Systems with Additive or Multiplicative UncertaintyAda ChengBoundary control systems arises naturally in many applications. Any modelling of real systems involve uncertainty. Sufficient conditions for well-posededness for additive or multiplicative uncertainty are presented through the use of matrix theory. …Journal of Mathematics and Statistics, Vol. 2, Issue 4 · 31 Dec 2006 · 6,137 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Phenotypically Suppressed Cancer Cell As a Therapeutic TargetKimberly D. Kyker, Jessica E. Thorpe, Satyendra S. Shenoy et al.Bladder cancer recurs in up to 70% of patients judged to be tumor-free after treatment. Like other cancers, delayed appearance of metastases is common. These findings suggest the malignant phenotype can be suppressed, to emerge later. Following up on previous research in our laboratory showing that normal extracellular matrix can suppress the malignant phenotype of bladder cancers, we here demonstrate … …American Journal of Pharmacology and Toxicology, Vol. 1, Issue 4 · 31 Dec 2006 · 6,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Design of a Complex Software System with ArchjavaDjamal Bennouar, Tahar Khammaci, Abderrezak HenniSoftware development by assembling components represents a very promising way for the design of high quality software at lower costs. The assembly is specified by the Architecture Description Languages (ADL). ArchJava is an ADL that is characterized by its independence from the application domain and its close position to the implementation level, thus making it very attractive for practitioners. Until … …Journal of Computer Science, Vol. 2, Issue 11 · 30 Nov 2006 · 6,414 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Virus AlgorithmsJyoti Kalyani, Karanjit S. Kahlon, Harpal Singh, Anu KalyaniSecurity of wired and wireless networks is the most challengeable in today's computer world. The aim of this study was to give brief introduction about viruses and worms, their creators and characteristics of algorithms used by viruses. Here wired and wireless network viruses are elaborated.
