Research ArticleOpen accessIn the abstractSelection of Spectral Filters for Optical Demultiplexer Via Same Source Different Filters Testing TechniqueMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah Supian, Malik SulaimanThis study aims to evaluate the effectiveness of selected color filter film for demultiplexer construction where only signals with certain wavelengths are allowed to pass through the demultiplexer while the other signal that carrying different wavelengths are absorbed. Characterization testing and analysis is done based on recorded data. Demultiplexer components are characterized by the Same Source at Different Filters (SSDF) … …Journal of Computer Science, Vol. 9, Issue 4 · 9 May 2013 · 6,247 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Thin-Film as Wavelength Filter in Wdm-Pof NetworkMohd Syuhaimi Ab. Rahman, L. S. Supian, Hadi Guna et al.Problem statement: Huge capacity for data transmission and bandwidth are becoming a need nowadays. High cost of implementation using optical fibers prevents utilization of the technology as wide as possible. Approach: Wavelength Division Multiplexing (WDM) was a technique that offers the solution for providing better bandwidth. WDM technique allows several signals that have different wavelengths to be transmitted in a … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 9 Dec 2011 · 7,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign Based on Intra-Class Correlation CoefficientsRobert Lew, Gheorghe DorosProblem statement: Reliability studies are concerned with the study of "consistency" or "repeatability" of measurements. Often times (but not always) the reliability coefficients are Intra-class Correlation Coefficients (ICC). Depending on the design or the conceptual intent of the study there are three types of intra-class correlation coefficients, termed intra-class correlation coefficients Case 1, 2 and 3, for measuring the reliability … …Current Research in Biostatistics, Vol. 1, Issue 1 · 30 Jun 2010 · 18,541 accessesView PDFCite
Research ArticleOpen accessIn the abstractSorting N-Elements Using Natural Order: A New Adaptive Sorting ApproachShamim Akhter, M. Tanveer HasanProblem statement: Researchers focused their attention on optimally adaptive sorting algorithm and illustrated a need to develop tools for constructing adaptive algorithms for large classes of measures. In adaptive sorting algorithm the run time for n input data smoothly varies from O(n) to O(nlogn), with respect to several measures of disorder. Questions were raised whether any approach or technique would … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractHybrid Photovoltaic Thermal (PV/T) Air and Water Based Solar Collectors Suitable for Building Integrated ApplicationsAdnan Ibrahim, Goh Li Jin, Roonak Daghigh et al.Problem statement: Experiments have been conducted to investigate the effect of mass flow rates on the electrical, thermal and combined of photovoltaic thermal efficiencies of the hybrid collectors. Approach: Two photovoltaic thermal solar collectors were designed and fabricated. The first collector, known as spiral flow absorber collector, designed to generate hot water and electricity. The second collector, known as single … …American Journal of Environmental Sciences, Vol. 5, Issue 5 · 31 Oct 2009 · 8,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtection for an Immediate Split Structure of Tree-Based EPON Architecture-Ideal Condition AnalysisMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: Ethernet Passive Optical Network (EPON) was proposed to overcome the bandwidth bottleneck at the Access Networks due to its simplicity, cost effective and wide spread deployment. A failure in access networks can cause serious problems, because access network transmit aggregated high speed traffic from hundreds of subscribers. Protection and restoration mechanisms have been applied in backbone networks, but … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,276 accessesView PDFCite
Research ArticleOpen accessIn the abstractImage Recognition Using Combination of Discrete Multi_Wavelet and Wavenet TransformDr Mikhled AlfaouriFocus of the method was to present image identification and labeling using new combination of dynamic transforms. This method is based on using the combination of the Discrete Multi-wavelet Transform (DMWT) and Wavenet Transform (WN). In this method, the resulting coefficients were computed by the proposed multi-wavelets transform for single-level decomposition. The low pass sub bands of the upper left … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermal Hydraulic Analysis of Double Ended Hot Leg Pipeline Break Accident in AP1000 ReactorM.M. Sadeghiazad, F. Choobdar RahimIn the present research, the Loss of Coolant Accident (LOCA), as a postulated accident in nuclear reactors, in its worst condition called large LOCA has been modeled. A specific type of large LOCA in which a totally guillotine break occurs in the hot leg pipe is the Double Ended Hot Leg (DEHL). Once the ‘LOCA’ occurs, the pipe is break … …Energy Research Journal, Vol. 11, Issue 1 · 14 May 2020 · 7,661 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhishing Website Detection Using Improved Multilayered Convolutional Neural NetworksHadia Bibi, Syed Rehan Shah, Mirza Murad Baig et al.The internet has become an essential part of many fields: Communication, entertainment, commerce, industrial production, agriculture, etc. Unfortunately, online users are vulnerable to various attacks; this could lead to financial damages and loss of personal information. Phishing is seen as an internet threat and a cybercrime where anyone can capture personal information and data by posing as a reliable source. … …Journal of Computer Science, Vol. 20, Issue 9 · 6 Jul 2024 · 6,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractHospital-Based Antibiotic Therapy in Benin: A Point Prevalence Survey at the Departmental and Teaching Hospital of Borgou-Alibori in 2022Cossi Angelo Attinsounon, Aldin Gnaha, Carine Laurence Yehouenou et al.Antimicrobial resistance is a public health problem. The main factor favoring the development of antibiotic resistance is the abusive or inappropriate use of antibiotics. This study is the first to take all services into account and aims to describe antibiotic therapy practices in the Departmental and Teaching Hospital of Borgou-Alibori (DTH-BA). Patients and methods: This was a cross-sectional, descriptive survey … …American Journal of Infectious Diseases, Vol. 19, Issue 4 · 10 Feb 2024 · 6,095 accessesView PDFCite
