Research ArticleOpen accessIn the abstractDetection and Diagnostic Approach of COVID-19 Based on Cough Sound AnalysisMuzhir Shaban Al-Ani, Thabit Sultan Mohammed, Awni Ismail Sultan et al.Coronavirus (COVID-19) started at the end of 2019 and then spread out around the world as a pandemic at the beginning of 2020. At that time, researchers began to work on detecting and diagnosing this virus, where many methods have been applied for this reason. This study focuses on how to diagnose coronavirus through patients’ cough. Accordingly, real samples were … …Journal of Computer Science, Vol. 17, Issue 6 · 29 Jun 2021 · 7,806 accessesView PDFCite
Research ArticleOpen accessIn the abstractContinuous Wavelet Transform Based Spectral Decomposition of 3d Seismic Data for Reservoir Characterization in Oyi Field, se Niger DeltaChukwuemeka Ngozi Ehirim, Andifon Sylvester AkpanContinuous Wavelet Transform (CWT) is one of the most used wavelet transform based spectral decomposition methods in the direct detection of hydrocarbons and as an indicator of stratigraphic variability due to its optimal time-frequency resolution and variable time window requirements. CWT based spectral decomposition was applied on a 3D Post Stack Time Migrated (PSTM) seismic data acquired over a producing … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 28 Apr 2017 · 7,796 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Needle-Leaved Species in Increasing the Risk of Fire by Using Remote Sensing, Case Study: Forests of Golestan, IranAkram Karimi, Sara Abdollahi, Hamid Reza Kabiri Balajadeh et al.The present research was conducted to determine the sensitivity of needle-leaved species compared to broad-leaved in causing a natural fire in Golestan province. Vegetation and moisture stresses of plants were studied in both needle and mixed leaved forest the fire occurred in 2010-2014. In order to examine the normal condition of each indicator, the time series was produced from 2000 … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 30 Mar 2018 · 7,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinancial Development and Economic Growth in Nepal: New intuitions from a Time Series Causality MethodUttam Paudel, Satish Chandra Bhatta, Umesh KhatriGeneralized empirical evidences about impact and direction of causality between financial development and economic growth ignoring the differences of structure and other factors seem less effective to understand the contributions of financial as well as real sector development to economic growth by country specific factors in Nepal. This paper has established the short run or long run relationship and the … …Journal of Social Sciences, Vol. 14, Issue 1 · 28 Mar 2018 · 8,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvolution of Time Concept in Physics and in PhilosophyC. Sivaram, Kenath Arun, O. V. KirenWhat is ’time’? This is a question that has perplexed many a physicist and philosophers alike. The perception of the passage of time appears ingrained in all biological systems where growth, evolution and decay of objects, etc. are measurable indicators of the passage of time. Here we look at various physical models of time, from Newtonian to relativistic. We also … …Physics International, Vol. 6, Issue 2 · 9 Jul 2015 · 8,964 accessesView PDFCite
Research ArticleOpen accessIn the abstractA MIXTURE DROPOUT MECHANISM IN A LONGITUDINAL STUDY WITH TWO TIME POINTS: A METHADONE STUDYZohreh Toghrayee, Parvin Jalili, Heng Chin Low, Ardavan TaghvaOne of the most important issues that confront statisticians in longitudinal studies is dropouts. A variety of reasons may lead to withdrawal from a study and produce two different missingness mechanisms, namely, missing at random and non-ignorable dropouts. Nevertheless, none of these mechanisms is tenable in most studies. In addition, it may be that not all of dropouts are nonignorable. … …Journal of Mathematics and Statistics, Vol. 10, Issue 3 · 26 Apr 2014 · 6,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasurement of Fibrinogen Concentration in the Plasma of Dogs: A Comparison Between Heat Precipitation and Modified Thrombin Clotting Time MethodLabrini V. Athanasiou, Theodoros A. Petanides, Manolis K. Chatzis, Manolis N. SaridomichelakisFibrinogen is a glycoprotein that plays a key role in blood clotting and is also a non-specific indicator of inflammation. The most widely used techniques for measuring plasma fibrinogen concentration include heat precipitation (Millar’s technique) and modified thrombin clotting time (Clauss method). Both techniques have been automated in a haematology analyzer (QBC-Vet Autoreader®, IDEXX; Millar’s technique) and in a newly … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 2 · 18 May 2013 · 7,453 accessesView PDFCite
Research ArticleOpen accessIn the abstractClinical and Functional Profile of Amyotrophic Lateral Sclerosis Patients: A One Year Follow UpMarco Orsini, Marcos R.G. de Freitas, Osvaldo J.M. Nascimento et al.Problem statement: Amyotrophic Lateral Sclerosis (ALS) is a progressive and degenerative disease that affects the anterior horn motor neurons of the spinal cord and pyramidal tracts. In Brazil, there are few epidemiological data on this disease. Recently, some important findings have been reported, allowing a better understanding on the underlying processes of neuronal death, as well as the characteristics of … …Neuroscience International, Vol. 2, Issue 1 · 6 Oct 2011 · 7,777 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Growth, Sensory Characteristic and pH as Potential Spoilage Indicators of Chinese Yellow Wet Noodles from Commercial Processing PlantsSuwaibah Ghaffar, Abdulamir AS, Fatimah Abu Bakar et al.Problem statement: This study was conducted to evaluate the potential use of microbial growth, sensory characteristic (odour) and pH as potential spoilage indicators of Chinese yellow wet noodles. Approach: Samples were collected from 3 commercial processing plants namely, Automated Processing (AP), Semi-automated Processing (SP) and Manual Processing (MP). The samples were kept at ambient temperature (28±2 °C) and monitored microbiologically … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 8,583 accessesView PDFCite
Research ArticleOpen accessIn the abstractVoltage Collapse Risk Associated to Under-Voltage Capacitive Compensation in Electric Power System OperationHeraldo Silveira Barbuy, Alexandre Rocco, Luiz Augusto Pereira Fernandes, Geraldo Caixeta GuimarãesProblem statement: In the operation of an Electric Power System (EPS), it has been usual to provide reactive power injection to avoid an under-voltage bus condition. In some situations an adequate voltage profile will not be a guarantee against Voltage Collapses (VCs) that may cause blackouts as seen in many occurrences around the world. The repeatedly injection of reactive power … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,258 accessesView PDFCite
