Research ArticleOpen accessIn the abstractA COMPARISION OF VARIOUS EDGE DETECTION TECHNIQUES IN MOTION PICTURE FOR IDENTIFYING A SHARK FISHShrivakshan Gopal Thiruvangadan, Chelliah ChandrasekarThe significant feature of detecting the motion image objects in this study it try identify the shark fish videos by removing the Background of the image. The main method involved in the detecting from the background is the foreground detection of the image. There are many techniques which usually ignore the fact that the background images consist of different image … …Journal of Computer Science, Vol. 9, Issue 11 · 18 Sep 2013 · 6,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Analysis on Same Filter Different Sources for Selection of Spectral Filters in Optical DemultiplexerMohammad Syuhaimi Ab-Rahman, Hadiguna, Latifah Sarah SupianThe cost effective demultiplexer based on POF is reported in this study. The demultiplexer is fabricated by combining optical splitter with the suitable filter for wavelength selection. Therefore this study we 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 … …Journal of Computer Science, Vol. 9, Issue 7 · 18 Jun 2013 · 6,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Multipath Routing and Wavelength Allocation Using Traffic Grooming in Optical Wavelength Division Multiplexing Mesh NetworksV. Rajamani, T. KavithaIn optical WDM mesh networks, traffic grooming is essential in order to utilize the bandwidth efficiently to minimize the cost and meet the user service requirement. By grooming traffic, it is possible to reduce the total cost of all Add drop multiplexer needed. Also for the high processing capability in a WDM network, the path should be capable of carrying … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,522 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical System Monitoring Based on Reflection Spectrum of Fiber Bragg GratingMohammad Syuhaimi Ab-Rahman, Nani Fadzlina Naim, Mastang Tanra, Harry RamzaProblem statement: This study presents fiber fault monitoring approaches for Fiber-to-the Home (FTTH) with a Passive Optical Network (PON). Current fiber fault monitoring approaches are difficult to be implemented due to its complexity and high loss as the amount of branches increase. Approach: A fiber fault monitoring scheme is proposed whereas Fiber Bragg Grating (FBG) is placed on each branch … …Journal of Computer Science, Vol. 8, Issue 6 · 28 Apr 2012 · 7,191 accessesView PDFCite
Research ArticleOpen accessIn the abstractCustomer-Made 3×3 Polymer Optical Fiber Splitter Based on Green Technology using Fusion TechniqueMohammad Syuhaimi Ab-Rahman, Nik Nur Syahirah Mohammad, Hadi Guna et al.Problem statement: Polymer Optical Fiber (POF) has many advantages making it the choice of today’s communication, especially in automotive industry. This communication requires low cost ways for much information to be sent simultaneously. Because of this, using Wavelength Division Multiplexing (WDM) concept, a low cost and green 3×3 POF splitter is fabricated. It is fabricated using cheap and easy-to-find tools … …Journal of Computer Science, Vol. 8, Issue 4 · 11 Feb 2012 · 6,842 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 abstractLinear Protection Schemes Analysis in Scattered Placement Fiber-To-The Home-Passive Optical Network Using Customer Access Protection Unit SolutionMohammad Syuhaimi Ab-Rahman, Siti Asma Che Aziz, Kasmiran JumariProblem statement: This study highlights on restoration scheme proposed against failure in working line at the drop region for Fiber-To-The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. Approach: Survivability scheme against failure is focused on scattered residence … …Journal of Computer Science, Vol. 8, Issue 1 · 26 Oct 2011 · 7,347 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Challenge for Routing Algorithms in Optical Multistage Interconnection NetworksMehrnaz Moudi, Mohamed OthmanProblem statement: A class of dynamic interconnection networks is Multistage Interconnection Networks (MINs) that connects input devices to output devices through a number of switch stages. MINs have assumed importance in recent years; because of their cost-effectiveness. Optical MINs are one type of MINs that have large transmission capacity in the communication networks. There is a major problem in Optical … …Journal of Computer Science, Vol. 7, Issue 11 · 29 Aug 2011 · 7,852 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Ultra-Precision Polishing of Large Aperture Reaction Bonded Silicon Carbide MirrorYong Shu, Yifan Dai, Ziwen Zheng, Shengyi LiProblem statement: Silicon Carbide (SiC) optical materials have become the first choice for mirrors in space optical systems and large ground-based optical systems due to their outstanding mechanical, physical and optical properties. Compared with traditional optical glasses, SiC optical materials are provided with the characteristics of high hardness and multiphase, which embarrass the high efficient fabrication of SiC mirrors with … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 10,815 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.
