Research ArticleOpen accessAll words, across the recordSmooth Formant Peak Via Discrete Tchebichef TransformNur Azman Abu, Ferda Ernawan, Fadzilah SalimWith the growth in computing power, speech recognition carries a strong potential in the near future. It has even become increasingly popular with the development of mobile devices. Presumably, mobile devices have limited computational power, memory size and battery life. In general, speech recognition operation requires heavy computation due to large samples per window used. Fast Fourier Transfom (FFT) is … …Journal of Computer Science, Vol. 11, Issue 2 · 10 Sep 2014 · 7,187 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordShortage Level of Matching Kidney and Pancreas Organs for Implant is EstimatedRamalingam ShanmugamOrgan transplants are increasingly done worldwide. The organ donors might be dead or alive. There are legal, ethical, medical and administrative issues to procure organs and to transplant them. However, the donor’s organs must fully match the recipient’s requirement before they are quickly transported as the time is the essence. The kidney or pancreas organs are more in demand. When … …International Journal of Research in Nursing, Vol. 4, Issue 2 · 1 Nov 2013 · 6,516 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparison and Analysis of Vertical Coherence in the Shallow Water of Two ocean regionV. G. Sivakumar, V. Rajendran, R. SaranyaNoise characteristics at shallow water is highly variable due to wave guide nature of the shallow water environment, reflection of noise from the bottom surface; due to biological activities and also due the sound speed in shallow water vary substantially. Thus noise field characterization is complex in shallow water. The ambient noise data was collected in the shallow water of … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 5 Jun 2013 · 6,488 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordComparative Analysis of Satellite Image Pre-Processing TechniquesT. Sree Sharmila, K. Ramar, T. SreeRenga RajaSatellite images are corrupted by noise in its acquisition and transmission. The removal of noise from the image by attenuating the high frequency image components, removes some important details as well. In order to retain the useful information and improve the visual appearance, an effective denoising and resolution enhancement techniques are required. In this research, Hybrid Directional Lifting (HDL) technique … …Journal of Computer Science, Vol. 9, Issue 2 · 1 Apr 2013 · 7,308 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHigh Frequency of Stop Codons in the Human Immunodeficiency Virus-1 Protease Gene Frame in Human Immunodeficiency Virus+ Individuals with Below Detectable Levels of Plasma Viremia During Highly Active Antiretroviral TherapyMagdalena Czubala, Kabo Matlho, Maria Arriaga et al.We performed sequence analysis of HIV-1 proviral protease gene fragment (560 base pairs) amplified from ex-vivo peripheral blood mononuclear cells of 83 HIV+ individuals with Below Detectable Levels (BDL) (<20-40 RNA copies/ml plasma) and detectable levels of plasma HIV viremia while on HAART. Noteworthy was the systematic presence of stop codons identified only in the BDL group and not in … …American Journal of Infectious Diseases, Vol. 8, Issue 3 · 14 Nov 2012 · 8,073 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance, Analysis of Filtering Schedule Using Deblocking Filter for the Reduction of Block Artifacts from MPEQ Compressed Document ImagesM. Anto Bennet, I. Jacob RaglendProblem statement: The visual effects of blocking artifacts can be reduce by using deblocking filter. Also with out smoothing the natural edges,the perceived quality of video sequence can be enchanced. This study propose a method to remove blocking artifacts in low bit-rate block based video coding. Approach: The proposed algorithm has two separate filtering modes, which are selected by pixel … …Journal of Computer Science, Vol. 8, Issue 9 · 8 Aug 2012 · 7,264 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordPerformance Analysis on 16-Channels Wavelength Division Multiplexing in Free Space Optical Transmission under Tropical Regions EnvironmentSalasiah Hitam, Siti Norziela Suhaimi, Ahmad Shukri Mohd Noor et al.Problem statement: Wavelength-Division-Multiplexing (WDM) is a promising technique for meeting the growing demand for increased bandwidth and various types of services in the optical access network. For wide area or metropolitan networks, fibers are deployed to provide huge bandwidth. In access networks, the fiber-to-the-home will partially solve the last mile problem. However, some environmentally sensitive area such as housing areas, … …Journal of Computer Science, Vol. 8, Issue 1 · 2 Nov 2011 · 10,358 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTrends in Maximum Daily Rainfall in Marginal Desert Environment: Signs of Climate ChangeKhaldoun A. Al-Qudah, Abdullah A. SmadiProblem statement: Change in intense precipitation has been used as an indicator for anticipated climate change. The trend in maximum daily rainfall in 10 rainfall stations distributed in the north and north east of Jordan has been investigated. Based on mean annual rainfall and geographic location, rainfall stations were divided into subhumid, semi-arid and arid stations. Approach: The regression approach … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 7,401 accessesView PDFCite
