Research ArticleOpen accessIn the abstractModified Curvelet Thresholding Algorithm for Image DenoisingAl-Dahoud Ali, Preety D. Swami, J. SinghaiProblem statement: This study introduced an adaptive thresholding method for removing additive white Gaussian noise from digital images. Approach: Curvelet transform employed in the proposed scheme provides sparse decomposition as compared to the wavelet transform methods which being nongeometrical lack sparsity and fail to show optimal rate of convergence. Results: Different behaviors of curvelet transform maxima of image and noise … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,261 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Critical Knowledge Characteristics on Degree of Inter-Firm Technology TransferA. W. Sazali, A. Haslinda, U. Jegak, C. R. RaduanProblem statement: The current issue on inter-firm technology transfer in the developing countries is centered on the efficiency and effectiveness of the transfer process by the Multinationals (MNCs). Thus, organizations in the developing countries are striving hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs) as an efficient mean … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,897 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Absorptive Capacity and Recipient Collaborativeness as Technology Recipient Characteristics on Degree of Inter-Firm Technology TransferA. W. Sazali, C. R. Raduan, U. Jegak, A. HaslindaProblem statement: As an efficient means to increase global competitiveness, technological capabilities and potential for local innovation, organizations in the developing countries are working hard to collaborate, learn and internalize their foreign partner’s technological knowledge by forming strategic alliances or International Joint Ventures (IJVs). Technology recipient characteristics, as one of the important actors/facilitators of inter-firm technology transfer, have increasingly become … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,805 accessesView PDFCite
Research ArticleOpen accessIn the abstractElementary Combinatorial-Probabilistic Proof of the Wallis and Stirling FormulasMikhail KovalyovThis short note provides a remarkably simple derivation of the Wallis and Stirling formulas based on elementary estimates applied to binomial coefficients. As a byproduct an elementary proof of the central limit theorem for the binomial distribution is also obtained. …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 8,088 accessesView PDFCite
Research ArticleOpen accessIn the abstractRobust Estimations as a Remedy for Multicollinearity Caused by Multiple High Leverage PointsArezoo Bagheri, Habshah MidiProblem statement: The Least Squares (LS) method has been the most popular technique for estimating the parameters of a model due to its optimal properties and ease of computation. LS estimated regression may be seriously disturbed by multicollinearity which is a near linear dependency between two or more explanatory variables in the regression models. Even though LS estimates are unbiased … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 8,251 accessesView PDFCite
Research ArticleOpen accessIn the abstractHardware Implementation of a Genetic Algorithm Based Canonical Singed Digit Multiplierless Fast Fourier Transform Processor for Multiband Orthogonal Frequency Division Multiplexing Ultra Wideband ApplicationsMahmud Benhamid, Masuri B. OthmanProblem statement: Ultra Wide Band (UWB) technology has attracted many researchers' attention due to its advantages and its great potential for future applications. The physical layer standard of Multi-band Orthogonal Frequency Division Multiplexing (MB-OFDM) UWB system is defined by ECMA International. In this standard, the data sampling rate from the analog-to-digital converter to the physical layer is up to 528 … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 7,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwarm Negative Selection Algorithm for Electroencephalogram Signals ClassificationNasser Omer Sahel Ba-Karait, Siti Mariyam Shamsuddin, Rubita SudirmanProblem statement: The process of epilepsy diagnosis from EEG signals by a human scorer is a very time consuming and costly task considering the large number of epileptic patients admitted to the hospitals and the large amount of data needs to be scored. Therefore, there is a strong need to automate this process. Such automated systems must rely on robust … …Journal of Computer Science, Vol. 5, Issue 12 · 31 Dec 2009 · 7,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fragile Watermarking Scheme for Image Authentication with Tamper Localization Using Integer Wavelet TransformP. MeenakshiDevi, M. Venkatesan, K. DuraiswamyProblem statement: In recent years, as digital media are gaining wider popularity, their security related issues are becoming greater concern. Method for authenticating and assuring the integrity of the image is required. Image authentication is possible by embedding a layer of the authentication signature into the digital image using a digital watermark. In some applications tamper localization is also required. … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 7,734 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Stripping Frequency on Semen Quality of Endangered Caspian Brown Trout, Salmo trutta caspiusSaeed Hajirezaee, Bagher Mojazi Amiri, Ali Reza MirvaghefiProblem statement: Because of dramatic declines in stocks of endangered Caspian brown trout males, Salmo trutta caspius in Caspian Sea, each male brooder is stripped indispensably more than once during the spawning season in other to artificial insemination in hatchery. The aim of the present study was to assay the changes of indicators of semen quality (sperm motility, sperm production, … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractForecasting Gold Prices Using Multiple Linear Regression MethodZ. Ismail, A. Yahya, A. ShabriProblem statement: Forecasting is a function in management to assist decision making. It is also described as the process of estimation in unknown future situations. In a more general term it is commonly known as prediction which refers to estimation of time series or longitudinal type data. Gold is a precious yellow commodity once used as money.
