Research ArticleOpen accessIn the abstractPOWER QUALITY DIAGNOSIS IN DISTRIBUTION NETWORK USING WAVELET TRANSFORMH. H. Goh, H. L. Ting, Q. S. Chua et al.Power quality is one of the most concerns to the electric power suppliers, equipment manufacturers and the users of various electrical and electronic equipments. This paper presents the use of a continuous wavelet transform to detect and analyse voltage sags and swells. Characteristics which include duration and magnitude of the investigated signals are measured. Unlike other approaches where the detection … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 26 Dec 2013 · 7,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpulse Radio Ultra Wide Band Based Mobile Adhoc Network Routing Performance AnalysisM. Sreedhar, C. VenkateshThis study presents with the routing overhead analysis of impulse radio - Ultra Wide Band based wireless networks which Employs Dynamic Nature Routing (EDNR) method for determining and selecting the stable route in Mobile Adhoc Network (MANET). This method requires only two sample packets and uses piggyback information on Route-Request (RREQ) and Route-Reply (RREP) packets during a route-discovery procedure. Conventional … …American Journal of Applied Sciences, Vol. 10, Issue 4 · 15 Apr 2013 · 5,891 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Working Integrated Model for the Diffusion of Construction InnovationAhmad Rahman Songip, B.H. Lau, Kamaruzaman Jusoff, Hayati Nor RamliConstruction industry is said to be low in innovation and adoption of innovations is necessary to gain competitive advantage in a liberalized and globalized marketplace. This study investigated the factors that influenced the diffusion of construction innovations and developed an integrated framework to improve the diffusion process. A conceptual model was developed to guide the study and the modification of … …American Journal of Applied Sciences, Vol. 10, Issue 2 · 9 Feb 2013 · 8,045 accessesView PDFCite
Research ArticleOpen accessIn the abstractDerivation of the Limits for Control Chart Using the Median Absolute Deviation for Monitoring Non-Normal ProcessK. S. Adekeye, P. I. AzubuikeProblem statement: The Shewhart and S control charts, in the literature, were combined to evaluate the stability of a process. These charts were based on the fundamental assumption of normality of the quality characteristics under investigation. Approach: In practice, the normality assumption was often violated by real life data, therefore, use of the Shewhart and S control charts on real … …Journal of Mathematics and Statistics, Vol. 8, Issue 1 · 24 Dec 2011 · 8,440 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 abstractAsymptotic Distribution of Coefficients of Skewness and KurtosisNarges AbbasiProblem statement: In literature, a classic method which has been used to recognize the distribution so far is the measurement of its skewedness and kurtosis. However, there remains a question: how would these measurements work for skewed normal distribution when the size of the sample is large? Approach: This research aimed to determine the asymptotic distribution of skewedness and kurtosis … …Journal of Mathematics and Statistics, Vol. 5, Issue 4 · 31 Dec 2009 · 9,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Morphological, Biochemical and Biological Studies of Halophilic Streptomyces sp. Isolated from Saltpan EnvironmentDeepika T. Lakshmipathy, Krishnan KannabiranProblem statement: Dermatophytes have developed resistance to the existing antifungal antibiotics. As a part of our continuous search we had isolated, identified and characterized actinomycetes from the halophilic environment having antagonistic activity against the dermatophytes namely Trichophyton, Microsporum and Epidermophyton. Approach: Actinomycetes were isolated from the soil sample collected from the Ennore saltpan region, Chennai, India and screened for antidermatophytic … …American Journal of Infectious Diseases, Vol. 5, Issue 3 · 30 Sep 2009 · 7,743 accessesView PDFCite
Review ArticleOpen accessIn the abstractNanoboticsRelly Victoria Virgil PetrescuNanobotics (or Nanorobotics) is a field of emerging technology that deals with the creation of robots whose components are typically the size of a molecule or nanometer (10-9 meters). More specifically, nanorobotics refers to nanotechnology, an engineering discipline that designs and builds nanorobots that have movement, processing and transmission characteristics, program execution, etc. Nanomachines are largely in the research and … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 19 Jul 2020 · 7,788 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Permutation Test for Comparing Two Correlated Receiver Operating Characteristic CurvesOkeh Uchechukwu Marius, Onyeagu SidneyThe area under the Receiver Operating Characteristic (ROC) curve (AUC) is a summary measure when comparing two ROC curves. However, this summary measure is less informative when two ROC curves cross and have the same AUCs. In order to detect differences between ROC curves and to be able to tackle the problem of exchangeability of the labels between two diagnostic … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 24 May 2020 · 8,132 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of the Efficacy of Landslide Susceptibility ModelsJordan Henrique de Souza, Gislaine dos Santos, Gabriela Guimarães Gouvêa de Oliveira et al.This research aims to analyze the efficacy of SHALSTAB, IPT, SAGA, SMORPH and modified SMORPH models in evaluating landslide susceptibility. Statistical analysis concerning both the efficacy of the models in the prediction of landslide risks and the concordance between the models according to landslide occurrence or non-occurrence was performed. For this work, logistic regression, Receiver Operating Characteristic (ROC) curves, Kappa … …American Journal of Environmental Sciences, Vol. 15, Issue 3 · 31 May 2019 · 8,846 accessesView PDFCite
