Research ArticleOpen accessIn the abstractDetermination of Kinetic Correction Coefficient of Fluid Flow Using a Generic Multiple Orifice Physical Scale Model StructureEmmanuel M. AdigioProblem statement: Diesel particulate filters are fast becoming integral parts of diesel engines, light and heavy duty, due to their potential in the reduction of particulate matter from exhaust gases and their noise muffling property. Consequently, several researchers are developing mathematical models for the study of fluid flow through the filter substrate and in the aiding of filter systems design. … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementing a Large Data Bus VLIW MicroprocessorWeng Fook Lee, Ali Yeon Md ShakaffMicroprocessors have grown tremendously in its computing and data crunching capability since the early days of the invention of a microprocessor. Today, most microprocessors in the market are at 32 bits, while the latest microprocessors from IBM, Intel and AMD are at 64 bits. To further grow the computational capability of a microprocessor, there are two possible paths. One method … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,945 accessesView PDFCite

This new emerging research field offers enormous opportunities for e-Science applications such as astrophysics, bioinformatics, aerospace modeling, cancer research etc. Grid involves coordinating and sharing of computing power, application, data storage, network resources … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,368 accessesView PDFCite
Research ArticleOpen accessIn the abstractAerodynamic Noise Prediction Using stochastic Turbulence ModelingArash Ahmadzadegan, Mehran TadjfarAmongst many approaches to determine the sound propagated from turbulent flows, hybrid methods, in which the turbulent noise source field is computed or modeled separately from the far field calculation, are frequently used. For basic estimation of sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations (turbulent noise source field). A simple and … …American Journal of Applied Sciences, Vol. 5, Issue 9 · 30 Sep 2008 · 7,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Stent Geometry on Phase Shift between Pressure and Flow Waveforms in Stented Human Coronary ArteryVahab Dehlaghi, Siamak Najarian, Mohammad Tafazzoli ShadpourShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Alterations of the phase shift between pressure and flow waveform created by a different stents were studied to compare the hemodynamic effects of stent design properties on restenosis in stented human coronary artery. Blood pressure waveforms were computed in three different sites, … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,252 accessesView PDFCite
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 abstractStability Analysis and Stability Chart for Unsaturated Residual Soil SlopeBujang B.K. Huat, Faisal Hj. Ali, R. S.K. RajooIn tropical residual soils most hill slope failures are caused by rainfall. It is therefore important to consider dynamic hydrological conditions when attempting to analyze the stability of residual soil slopes. This paper describes a coupled hydrology/stability model that has been developed to overcome the limitations of the standard method of analysis used to investigate stability of tropical soil slopes. … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,325 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Real-time Image Processing with a Compact FPGA-based ArchitectureRidha Djemal, Didier Demigny, Rached TourkiThis study have presented a filed programmable gate array implementation of a real time video smoothing algorithm. In comparison with smoothing video techniques like deblocking filters in H.264 or smoothing in JPEG2000, the proposed method is implemented in hardware and its computational cost and complexity are reduced where all pixel processing related to uncompressed video is done on the fly. … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 7,001 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Sentiment-Based Evaluation of Museum Display Design through Hybrid IndoBERT and Rule-Based LexiconErneza Dewi Krishnasari, Yaddarabullah, Bayyinah Nurrul Haq et al.Traditional museums remain vital cultural institutions but face persistent challenges in engaging contemporary audiences. The Wayang Museum in Indonesia, despite partial digital renovation, continues to rely heavily on static, text-based displays that often hinder visual comfort and informational comprehension. Conventional sentiment analysis techniques have demonstrated limitations in accurately capturing the subtle feedback from visitors, particularly within the culturally nuanced contexts … …Journal of Computer Science, Vol. 22, Issue 5 · 30 May 2026 · 1,326 accessesView PDFCite
