Research ArticleOpen accessIn the keywordsKernel Density Estimation for Interdeparture Time of GI/G/1 QueuesHsing Luh, Berlin WuThe departure process of a single queue has been studied since the 1960s. Due to its inherent complexity, closed form solutions for the distribution of the departure process are nearly intractable. In this study, kernel type estimators of the density of interdeparture time in a GI/G/1 queue are studied. Uniform strong consistency of the estimators in a GI/G/1 queue and … …Journal of Mathematics and Statistics, Vol. 1, Issue 1 · 31 Mar 2005 · 6,585 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Mathematical Modeling of the Turbulence Combustion Biodiesel in a Compression Ignition Engine: Theoretical FrameworkFrancis Mouzong Bongne, Zacharie Merlin Ayissi et al.The present work proposes a new model for biodiesel combustion in an internal combustion engine. This model first includes the balance equations of gas dynamics with heat release. Secondly, a model with special properties that take into account turbulence effects is incorporated. The chemical models implemented in this study are for a biofuel used at less than 100% and for … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 4 · 30 Sep 2024 · 5,021 accessesView PDFCite
Review ArticleOpen accessIn the keywordsNeutrino Mass Mechanisms in 3-3-1 Models: A Short ReviewCarlos Antônio de Sousa PiresIn this study we review some mechanisms that provide light neutrinos in the framework of 3-3-1 gauge models without exotic leptons. In regard to the minimal 3-3-1 model, we call the attention to the fact that the perturbative regime of the model goes until 5 TeV. This requires alternative mechanisms in order to generate light neutrinos. In this review we … …Physics International, Vol. 6, Issue 1 · 28 Aug 2015 · 8,161 accessesView PDFCite
Research ArticleOpen accessIn the keywordsA Comparison between Electrical and Optical Chromatic Dispersion Compensation in Wavelength Divison Multiplexing Network Regarding to Electrical Pulse ShapesMohammad Syuhaimi Ab-Rahman, Majid MoghaddasiProblem statement: Besides of some impairment that has been inherited form single channel, specialists confronted with new obstacles in WDM implementation which bared them for achieving desired performance. Although Chromatic Dispersion (CD) exists in single channel too, it can worsens new nonlinearities which are occurs just in WDM systems. So CD compensation in WDM is even more vital than single … …Journal of Computer Science, Vol. 8, Issue 1 · 29 Oct 2011 · 6,920 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMethods of Utilizing Tropical Peat Land for Housing SchemeYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper discusses some of the methods and recent technologies in utilizing cheap marginal land such as tropical peat for housing scheme. Buildings on peat are usually suspended on piles, but ground around it may still settle. Therefore a suitable method of construction should be tackle to overcome serious problem such as localized sinking and slip failure, massive primary and … …American Journal of Environmental Sciences, Vol. 3, Issue 4 · 31 Dec 2007 · 6,669 accessesView PDFCite
Research ArticleOpen accessIn the keywordsCompressibility Behavior of Tropical Peat Reinforced with Cement ColumnsYouventharan Duraisamy, Bujang B.K. Huat, Azlan A. AzizThis paper presents the compressibility of tropical peat reinforced with cylindrical cement columns. When a cement column is installed vertically in peat, its compressibility is reduced because of the hardened skeleton matrix formed by cement particles bonding with adjacent soil particles in the presence of pore water. The effects of the cement column diameter on the compressibility have been investigated … …American Journal of Applied Sciences, Vol. 4, Issue 10 · 31 Oct 2007 · 7,434 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLarge Eddy Simulation of an Ammonia JetM. Salinas-Vazquez, A. Espinosa, E. Barrios, W. VicenteA compressible jet flow of ammonia was studied through a series of Large Eddy Simulations. Simulations were focused in the zone where the inertial effects are much bigger than the gravitational ones. The ammonia jet is discharged into an air medium and the gases are treated as a two non-reactive ideal gas mixture. Different simulations were performed, going from the … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractParameter-Expanded Data Augmentation for Analyzing Nominal Data With Missing Values Using Multinomial Probit ModelsSuwash Silwal, Xiao ZhangNominal data occur in many scientific fields, such as health-related studies, transportation, and econometrics. Due to the ubiquitousness of missing data, it is inevitable to analyze nominal data with missing values. As is well known, statistical methods for analyzing nominal variables are quite limited. The Multinomial Probit (MNP) model has been an essential tool for analyzing nominal categorical data, but … …Journal of Mathematics and Statistics, Vol. 22, Issue 1 · 23 May 2026 · 1,804 accessesView PDFCite
Research ArticleOpen accessIn the abstractExploring the Impact of Incorporating Fine-Grained Materials on the Resistance Characteristics of Cement-Reinforced ClaySayed Amirhossein Hosseini Chaleshtori, Mohammad Alibabaei ShahrakiThis study, conducted with meticulous attention to detail, examined the influence of fine-grained materials on the resistance components of clay, with and without cement reinforcement. Micro-silica, perlite, crystal barite, gypsum, silica and talc were added to investigate this matter and samples were created and modeled under standard laboratory conditions. The current study aimed to examine the effectiveness of organic granules … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 13 Aug 2024 · 5,579 accessesView PDFCite
Research ArticleOpen accessIn the abstractNon-Antibiotic Immunomodulatory Combination Treatment for Staphylococcus aureus Infections: In vitro Preliminary Studies IJatna Isha Rivas Zarete, Dominique Lyles, Benjamin Adu-AddaiDespite advancements in prevention measures, infectious mastitis is a common disease of economic significance in cattle. Clinical mastitis affects 20 to 25% of cows each year. Staphylococcus aureus (S. aureus) causes an estimated 10-11.7% of clinical bovine infectious mastitis cases in the US. Antibiotic therapy tends to fail 50% of the time and nature and vaccine immunity usually fails, due … …American Journal of Infectious Diseases, Vol. 18, Issue 4 · 14 Feb 2023 · 5,677 accessesView PDFCite
