Research ArticleOpen accessIn the abstractNonlinear Growth Models for Modeling Oil Palm Yield GrowthAzme Khamis, Zuhaimy Ismail, khalid Haron, Ahmad Tarmizi MohammedThis study provided the basic needs of parameters estimation for nonlinear growth model such as partial derivatives of each model, determination of initial values for each parameter and statistical tests of industrial usage. Twelve nonlinear growth models and its partial derivatives for oil palm yield growth are presented in this study. The parameters are estimated using the Marquardt iterative method … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 15,101 accessesView PDFCite
Research ArticleOpen accessIn the abstractValidation of Some Bridge Pier Scour Formulae Using Field and Laboratory DataThamer A. Mohamed, Megat J.M.M. Noor, Abdul H. Ghazali, Bujang B.K. HuatEstimation of maximum local scour depth at the bride pier site is necessary for the safety and economy of the designed bridge. Numerous formulae are available and almost all of these formulae were developed based on laboratory data. Validation of these formulae is necessary in order to ascertain which of the formulae will give a reasonable estimate of the local … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 7,826 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Environmental Performance-HSEQ Management System, Regarding the International and Iranian Oil and Gas General ContractorsJ. Nouri, M. Abbasspour, E. Roayaei, H. NikoomaramThe ever-increasing significance of the health, safety, environment and quality Management system has led general contractors including those involved in the oil and gas industry to place the implementation of this integrated system on their agenda, in a way that the implementation and execution of this system is considered as one of their operation and development strategies. The purpose of … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 7,085 accessesView PDFCite
Review ArticleOpen accessIn the abstractEEG-based Processing and Classification Methodologies for Autism Spectrum Disorder: A ReviewGunavaran Brihadiswaran, Dilantha Haputhanthri, Sahan Gunathilaka et al.Autism Spectrum Disorder is a lifelong neurodevelopmental condition which affects social interaction, communication and behaviour of an individual. The symptoms are diverse with different levels of severity. Recent studies have revealed that early intervention is highly effective for improving the condition. However, current ASD diagnostic criteria are subjective which makes early diagnosis challenging, due to the unavailability of well-defined medical … …Journal of Computer Science, Vol. 15, Issue 8 · 23 Aug 2019 · 10,401 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Analysis of Deep Learning Libraries: TensorFlow and PyTorchFelipe Florencio, Thiago Valenç, Edward David Moreno, Methanias Colaço JuniorThrough the increase in deep learning study and use, in the last years there was a development of specific libraries for Deep Neural Network (DNN). Each one of these libraries has different performance results and applies different techniques to optimize the implementation of algorithms. Therefore, even though implementing the same algorithm and using different libraries, the performance of their executions … …Journal of Computer Science, Vol. 15, Issue 6 · 11 Apr 2019 · 10,293 accessesView PDFCite
Review ArticleOpen accessIn the abstractDoes Intellectual Capital Affect the Volatility of Returns? An Empirical Investigation on Italian Listed CompaniesBrett W. Cantrell, Daniela Coluccia, Stefano Fontana, Silvia SolimeneIn modern information economies, economic success increasingly depends on the ability to apply knowledge and to transform it into firm value. While intellectual capital plays a critical role in firm success, it is an intangible asset that is difficult to measure and that is unrecorded by the firm. Difficulties in measuring intellectual capital, as well as the dynamic nature of … …American Journal of Applied Sciences, Vol. 14, Issue 12 · 10 Jan 2018 · 8,520 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Skid Resistance for Different Roadway Surface TreatmentsOsama A. Abaza, Tanay Datta Chowdhury, Mahmoud ArafatPavement skid resistance impacts road functionality and can affect user safety and vehicle operation costs. This study was an investigation of the effect of sealcoats on skid resistance. Seven different sealcoats-fog seal, chip seal, slurry seal, sand seal, high-friction seal, cape seal, and glass seal-were lab and field tested. Laboratory samples were further tested in the field on pavement sections. … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 10 Nov 2017 · 8,136 accessesView PDFCite
Research ArticleOpen accessIn the abstractSelf-Perceived Entrepreneurship Skills for Undergraduates of Private University in MalaysiaLeow Meng Chew, Lau Siong Hoe, Tan Choo Kim, Lillian Wang Yee KiawThis study was conducted on a random group of undergraduates in one of the private university in Malaysia to assess the self-perceived entrepreneurial skills of the undergraduates. As there was no standard instrument for this purpose, a simple questionnaire consisting of twelve questions was devised and used. The results were analyzed and reported by running the data in a few … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 3 Jun 2016 · 7,489 accessesView PDFCite
Research ArticleOpen accessIn the abstractExact Permutation Algorithm for Paired Observations: A General and Efficient VersionDavid T. MorseFor the better part of a century, methods have been illustrated for the enumeration of all possible permutations of cases from which an exact characterization of the likelihood of obtaining results as or more extreme as that observed may be determined without having to rely on parametric assumptions or schemes that may be only asymptotically correct. The challenge is the … …Journal of Mathematics and Statistics, Vol. 10, Issue 4 · 5 Jan 2015 · 6,672 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransformation Box-Cox for Stabilisation of Diversity in Group Random DesignYenny Sylvia, Djunaidy SantosoIn the field of research, there are a variety of statistical methods used. Hypothesis testing is one test that is often used to obtain the conclusions of the research conducted. One hypothesis testing that is often used is the testing of hypotheses through ANOVA (Box et al., 1978). However, in determining the validity of a hypothesis is obtained, there are … …Journal of Computer Science, Vol. 11, Issue 1 · 22 Sep 2014 · 7,175 accessesView PDFCite
