Research ArticleOpen accessIn the abstractSimulation of the Pedestrians' Influence to the Capacity of Motorised Vehicles in a RoundaboutT. Tollazzi, T. Lerher, M. ŠramlA new approach is suggested for dimensioning roundabouts with mathematical modeling of traffic flows using the discreet simulation method, and considering the statistically evaluated entry data for vehicles’ and pedestrians’ traffic flows. The simulation results are useful when determining the capacity of the roundabouts, which will function in different circumstances. The presented model derives from the expected time void in … …American Journal of Applied Sciences, Vol. 5, Issue 1 · 31 Jan 2008 · 6,901 accessesView PDFCite
Research ArticleOpen accessIn the abstractSome Algorithms to Identify Rational Structures in Stochastic Processes with ExpectationsConcepción González-Concepción, María Candelaria Gil-Fariña, Celina Pestano-GabinoThis research was concerned with the identification of rational models in stochastic processes and we use the Padé-Laurent Approximation to identify a Transfer-Function Model with Expectations. We mention the T-table method and focus in studying the generalised epsilon-algorithm, emphasizing the main role of the statistical significance of their numerical entries. Empirical work is made for non-causal TF models using both … …Journal of Mathematics and Statistics, Vol. 3, Issue 4 · 31 Dec 2007 · 6,754 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Reconfigurable Execution Core for Merged DSP MicrocontrollerA. K. Rath, P. K. MeherThe study presents an execution core which can be reconfigured either for calculation of digital convolution or for computation of discrete orthogonal transform by appropriate local buffer initialization of processing cells. It is shown that the data flow pattern can be changed by a single bit control signal. The proposed core can be connected to port 1 of Intel 8051 … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractAsymptotic Behavior for Solution of Reaction-Diffusion SystemsM. Yahi, K. SaoudiThe existence, uniqueness, and asymptotic behavior of the solution of a balanced two-component reaction-diffusion system have been investigated. It was shown that a global and unique solution existed and its second component can be estimated using the Lyapunov Functional. It was, also, demonstrated that each component of the solution converged, at infinity, to a constant which can be found in … …Journal of Mathematics and Statistics, Vol. 3, Issue 3 · 30 Sep 2007 · 6,849 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrevalence of Oncogenic HPV Types in Sardinia (Italy): Implications for the Impact of Prophylactic Anti-HPV VaccinesStefania Montisci, Sabrina Pitzalis, Marianna Greco et al.Infection with high-risk HPV genotypes is considered an essential step in cervical carcinogenesis. Recently, prophylactic anti-HPV vaccines have shown to provide effective protection in clinical trials. However, protection appears to be type-restricted, thus, its real extent will depend on HPV types prevalence in the target population. Here we report HPV prevalence in 555 Italian women with various stages of HPV-related … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 7,040 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultistage Median Ranked Set Sampling for Estimating the Population MedianAbdul Aziz Jemain, Amer Al-Omari, Kamarulzaman IbrahimWe modify RSS to come up with new sampling method, namely, Multistage Median Ranked Set Sampling (MMRSS). The MMRSS was suggested for estimating the population median and to increase the efficiency of the estimator for specific value of the sample size. The MMRSS was compared to the Simple Random Sampling (SRS), Ranked Set Sampling (RSS) and Median Ranked Set Sampling … …Journal of Mathematics and Statistics, Vol. 3, Issue 2 · 30 Jun 2007 · 7,148 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Merged DSP Microcontroller for Embedded Systems using Discrete Orthogonal TransformA. K. Rath, P. K. MeherIn this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be possible to … …Journal of Computer Science, Vol. 2, Issue 5 · 31 Aug 2006 · 6,921 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simulation-Based Comparison of Multimedia Traffic Prioritization Schemes for High-Performance Input-Queued Packet SwitchesSalman A. AlQahtaniThis study investigates the problem of enabling Quality of Service (QoS) of multimedia traffic at the input port of high-performance input-queued packet switches using a simulation-based evaluation. We focus on the possibility of assuring QoS of multimedia traffic in such switches by implementing traffic prioritization at the input port where each input-queue has been modified to provide a separate buffer … …Journal of Computer Science, Vol. 2, Issue 4 · 30 Apr 2006 · 7,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeta Architecting: Towered a New Generation of Architecture Description LanguagesAdel Smeda, Tahar Khammaci, Mourad OussalahThe techniques of meta-modeling and meta-levels have become a mature concept and have been largely used to solve real problems in programming languages, distributed environments, knowledge representation, or data bases. In this article it is shown how the same techniques can be applied in component-based software architecture. It also shown the need to propose mechanisms of reflexivity within the domain … …Journal of Computer Science, Vol. 1, Issue 4 · 31 Dec 2005 · 6,483 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Integrated Production Scheduling System in the Process IndustryMohamed K. Omar, Yasothei A.P. Suppiah, Siew C. TeoThis study introduces a three-level hierarchical production planning and scheduling approach developed and implemented in a resin factory. Our approach proposes at the first level a mixed-integer linear programming for solving the aggregate planning model. At the second level, a weighted-integer goal-programming model is developed to disaggregate the developed aggregate plans. A sequencing algorithm is developed for the third level … …Journal of Computer Science, Vol. 1, Issue 3 · 30 Sep 2005 · 6,867 accessesView PDFCite
