Research ArticleOpen accessIn the abstractNumerical Solution of the Taylor-Quette Flow Problem: A Commodious Statistical ApproachAyoob Karimi, Hassan Zeytoonian, Shahin NavardiProblem statement: The main problem in solving of the Boltzmann equation by statistical methods is its long computational time (CPU time). The problem of decreasing of CPU time usage in statistical solution methods of Boltzmann equation for rarefied vortex flows was studied. Approach: In this study the Boltzmann equation in a rarefied Taylor-Quette flow regime was solved using the new … …Physics International, Vol. 1, Issue 1 · 31 Mar 2010 · 7,782 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Statistical Speech Segmentation Using Connectionist ApproachM. S. Salam, Dzulkifli Mohamad, S. H. SallehProblem statement: Speech segmentation is an important part for speech recognition, synthesizing and coding. Statistical based approach detects segmentation points via computing spectral distortion of the signal without prior knowledge of the acoustic information proved to be able to give good match, less omission but lot of insertion. These insertion points dropped segmentation accuracy. Approach: This study proposed a fusion … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of MultiScale Hidden Markov Modeling Wavelet Coefficients to fMRI Activation DetectionFangyuan Nan, Yaonan Wang, Xiaoping MaProblem Statement: The problem of detection of functional magnetic resonance images (fMRIs), that is, to decide active and nonactive regions of human brain from fMRIs is studied in this paper. fMRI research is finding and will find more and more applications in diagnosing and treating brain diseases like depression and schizophrenia. At its initial stage fMRI detection are pixel-wise methods, … …Journal of Mathematics and Statistics, Vol. 4, Issue 4 · 31 Dec 2008 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Maturity Level in Laying Hen Manure by Chemical and Thermogravimetric AnalysisAlice Dall’Ara, Francesco Antolini, Laura Billi et al.This study aims at investigating maturity levels in manure from laying hens in order to encourage its agronomic re-utilization. In fact the use of unstable/insufficiently mature manure could potentially damage both soils and crops. Effective, easy to reproduce methods are needed in order to assess bio-stabilisation and maturity levels, particularly for biomass that has not undergone conventional composting. This study … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,542 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Probability Curves Obtained from 2 Quantitative Allergen-specific IgE Assays: FEIA and 3gAllergyTMT. M. Li, T. Chuang, S. M. Li, D. Hovanec-BurnsThe validity and benefit of probability curves in allergen-specific IgE (sIgE) testing and their applicability to more than a few allergens are still pending. One study[1] presented probability curves for 4 food allergens and proposed decision points to rule out the need for food challenges in his clinic. Since then, such cutoffs were reported by Boyano-Martinez[2] to be dependent on … …American Journal of Immunology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractPossibility and Evidence-Based Reliability Analysis and Design OptimizationHong-Zhong Huang, Liping He, Yu Liu et al.Engineering design under uncertainty has gained considerable attention in recent years. A great multitude of new design optimization methodologies and reliability analysis approaches are put forth with the aim of accommodating various uncertainties. Uncertainties in practical engineering applications are commonly classified into two categories, i.e., aleatory uncertainty and epistemic uncertainty. Aleatory uncertainty arises because of unpredictable variation in the performance … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 1 · 26 Mar 2013 · 7,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractManagement of Data for Health Performance Measurement in the Industrialized Dairy HerdMogens Agerbo Krogh, Carsten EnevoldsenOne part of dairy herd management is to handle disease occurrence by means of health promotion, disease prevention, timely medical treatments, or eradication of disease. Supporting this part of herd management is an essential task for the cattle veterinarian. The study objective was to identify principles and tools for analysis of herd health data in industrialized dairy herds. The analysis … …American Journal of Animal and Veterinary Sciences, Vol. 7, Issue 4 · 23 Nov 2012 · 8,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Simple Robust Control Chart Based on MADMoustafa Omar Ahmed Abu-ShawieshControl charts are one of the most powerful tools used to detect aberrant behavior in industrial processes. The Shewhart S-control chart is one of the most widely used statistical process control techniques developed to control the process variability based on the fundamental assumption that the underlying distribution of the quality characteristic is normal. When the underlying normality assumption is not … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 14,264 accessesView PDFCite
Research ArticleOpen accessIn the abstractNatural Repellent Anthraquinone Applied on Cereal Grain Seeds and Seedlings Against Pigeons (Columba livia) in CaptivityKan Khoomsab, Itsara TangsuwanThis research aims to test the effects of cassia leaf extract on the eating behavior of pigeons for application as a natural repellent. Senna siamea (Cassia) leaves were oven-dried and blended into fine pieces and processed by the simplest extraction method (maceration) with ethyl alcohol 70% solution and were then extracted with hot continuous extraction (Soxhlet extraction) with ethyl alcohol … …American Journal of Agricultural and Biological Sciences, Vol. 14, Issue 1 · 16 Dec 2019 · 7,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Components of Data Governance Framework for MOOC Providers in IndonesiaYakob Utama Chandra, Harjanto Prabowo et al.The COVID-19 pandemic had a universal and synchronous impact on all countries globally, leading to the implementation of the social distancing policy that mandated all activities take place within one's own house. One of the implementations is distance education. Since the pandemic, e-learning, which is the dominant use of information technology in the education sector, has gained widespread recognition and … …Journal of Computer Science, Vol. 20, Issue 12 · 31 Oct 2024 · 4,777 accessesView PDFCite
