Research ArticleOpen accessIn the abstractA FAST AND ACCURATE METHOD FOR AUTOMATIC CORONARY ARTERIAL TREE EXTRACTION IN ANGIOGRAMSRohollah Moosavi Tayebi, Puteri Suhaiza Binti Sulaiman, Rahmita Wirza et al.Coronary arterial tree extraction in angiograms is an essential component of each cardiac image processing system. Once physicians decide to check up coronary arteries from x-ray angiograms, extraction must be done precisely, fast, automatically and including whole arterial tree to help diagnosis or treatment during the cardiac surgical operation. This application is very helpful for the surgeon on deciding the … …Journal of Computer Science, Vol. 10, Issue 10 · 27 Jun 2014 · 8,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Channel Estimation Technique for Complexity Reduction of Least Minimum Mean Square ErrorHany Mohamed El-Ansary, Hussein Ghouz, Ashraf Mamdouh Aziz, Gamal MabroukChannel estimation technique is to predict the frequency response of the radio channel using pilot signal. Channel estimation technique is important part of LTE receiver design. Such technique is used to recover the transmitted signal correctly and to know how the channel conditions are changed over frequency and time. Each channel estimator has a specified complexity computed according to its … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 6,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Newton Raphson Algorithm for Optimizing Transmission Control Protocol PerformanceJ. Viji Priya, S. SuppiahWireless networks are growing rapidly. TCP is the most widely-used protocol on Internet and so optimizing TCP performance is very important for fast efficient data transfer. The different existing TCP variants and solutions they have not been analyzed together to identify the bottlenecks in wireless networks. TCP has a major problem in its congestion control algorithm which does not allow … …Journal of Computer Science, Vol. 9, Issue 5 · 20 May 2013 · 6,302 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Multidictionary Based Text CompressionM. Baritha Begum, Y. VenkataramaniThe amount of digital contents grows at a faster speed as a result does the demand for communicate them. On the other hand, the amount of storage and bandwidth increases at a slower rate. Thus powerful and efficient compression methods are required. The repetition of words and phrases cause the reordered text much more compressible than the original text. On … …Journal of Computer Science, Vol. 8, Issue 12 · 8 Nov 2012 · 6,942 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality of Service Aware Reverse Pathad-Hoc On-Demand Distance Vector ProtocolK. G. Santhiya, N. ArumugamMobile Ad-hoc Network (MANET) is aninfra structureless network that does not require any built-in infra structure and central control. Due to very fast mobility of nodes, there will be drastic changes in the network topology. So an adaptive routing protocol is needed for effective and reliable routing in MANET. Ad-hoc On-demand Distance Vector (AODV) routing protocol is the efficient and … …Journal of Computer Science, Vol. 8, Issue 11 · 20 Sep 2012 · 7,061 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Fuzzy Neural Approach for Medical Image RetrievalC. Sriramakrishnan, A. ShanmugamImage retrieval based on a query image is necessary for effective and efficient use the information that is stored in medical image databases. Medical Image Retrieval is difficult as not only the localization and directionality of human visual system is to be considered but also the pathological condition. Image identification and segmentation for feature extraction pose a challenge to image … …Journal of Computer Science, Vol. 8, Issue 11 · 8 Sep 2012 · 6,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C. ChellappanProblem statement: The Security in WSN has become a challenge because of its inherent limitations of resources imposed on the sensor nodes. Authentication and key management scheme allows WSNs to be used with confidence and maintains integrity of data in sensor networks. Approach: In the WSN limited resource scenario the generation of public key done and are randomly pre distributed … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 18 Aug 2012 · 7,339 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Optimal Load Sharing Technique For Grid ComputingD. Ramesh, A. KrishnanProblem statement: Grid and Cloud Computing is the fast growing industry, in which the grid computing shares the resources in the organization in an effective manner. Resource sharing requires more optimized algorithmic structure, otherwise the waiting time and response time are increased and the resource utilization is reduced. Approach: In order to avoid such reduction in the performances of the … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 29 May 2012 · 6,965 accessesView PDFCite
Research ArticleOpen accessIn the abstractEfficient Web Usage Miner Using Decisive Induction RulesK. Poongothai, S. SathiyabamaProblem statement: Web usage mining is the technique of extracting useful information from server logs (user’s history) and finding out what users are looking for on the Internet. This type of web mining allows for the collection of Web access data for Web pages. Scope: The web usage data provides the paths leading to accessed Web pages with prefrences and … …Journal of Computer Science, Vol. 8, Issue 6 · 14 Mar 2012 · 6,899 accessesView PDFCite
Research ArticleOpen accessIn the abstractFPGA-Based Architecture for a Generalized Parallel 2-D MRI Filtering AlgorithmSami Hasan, Said Boussakta, Alex YakovlevProblem statement: Current Neuroimaging developments, in biological research and diagnostics, demand an edge-defined and noise-free MRI scans.
