Research ArticleOpen accessIn the abstractPERFORMANCE ANALYSIS OF BRAIN TUMOR DIAGNOSIS BASED ON SOFT COMPUTING TECHNIQUESP. Shantha Kumar, P. Ganesh KumarComputed tomography images are widely used in the diagnosis of brain tumor because of its faster processing, avoiding malfunctions and suitability with physician and radiologist. This study proposes a new approach to automated detection of brain tumor. This proposed work consists of various stages in their diagnosis processing such as preprocessing, anisotropic diffusion, feature extraction and classification. The local binary … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 27 Dec 2013 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractImaging Spectroscopy and Light Detection and Ranging Data Fusion for Urban Features ExtractionMohammed Idrees, Helmi Zulhaidi Mohd Shafri, Vahideh SaeidiThis study presents our findings on the fusion of Imaging Spectroscopy (IS) and LiDAR data for urban feature extraction. We carried out necessary preprocessing of the hyperspectral image. Minimum Noise Fraction (MNF) transforms was used for ordering hyperspectral bands according to their noise. Thereafter, we employed Optimum Index Factor (OIF) to statistically select the three most appropriate bands combination from … …American Journal of Applied Sciences, Vol. 10, Issue 12 · 28 Oct 2013 · 7,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractYoung Adult Perception and Attitude Toward Conspicuous Consumption and PovertyToni Yvette Sims-MuhammadThis study explores the perception and attitude of young adults toward conspicuous consumption portrayed in mass media and their conception of poverty. Many young adults may not realize the cadre of consumerist ideologies portrayed throughout the culture and mass media such as buy more, buy newer and improved, buy wants over needs, buy comparatively, buy exclusively and buy to prove. … …Journal of Social Sciences, Vol. 8, Issue 4 · 20 Mar 2013 · 7,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Fuzzy Petri-Net Based Conceptual Model for Risk Prediction in Enterprise Resource Planning Acquisition Decisions for Small and Medium EnterprisesVijayakumar Bharathi, Dhanya Pramod, Ramakrishnan RamanThis study identifies and evaluates certain critical pitfalls in the acquisition phase of ERP adoption in Small and Medium Enterprises (SMEs) and develops a model for evaluating the risk of failure. On the acquisition stage a set of risks has been identified based on past research work and each of these risks have been explained through a set of well-defined … …Journal of Computer Science, Vol. 9, Issue 1 · 18 Mar 2013 · 7,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Evaluation of Adaptive Filter and Neuro-Fuzzy Filter in Artifacts Removal From Electroencephalogram SignalPaulchamy Balaiah, IlavennilaProblem statement: This study presents an effective method for removing mixed artifacts (EOG-Electro-ocular gram, ECG-Electrocardiogram, EMG-Electromyogram) from the EEG-Electroencephalogram records. The noise sources increases the difficulty in analyzing the EEG and obtaining clinical information. EEG signals are multidimensional, non-stationary (i.e., statistical properties are not invariant in time), time domain biological signals, which are not reproducible. It is supposed to contain … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 15 Aug 2012 · 7,090 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Polydextrose on Feces Consistency and Macronutrient Digestibility in Healthy DogsK. Vasupen, C. Yuangklang, A. C. Beynen, A. W.C. EinerhandProblem statement: There is evidence that the addition of 3% STA-LITE® polydextrose to a dry food reduces clinical signs of osteoarthritis in dogs. For the application of polydextrose as functional ingredient of dog foods, information as to its impact on the acceptance of food, feces consistency, fecal odor and digestibility of macronutrients and minerals is required. Approach: A feeding experiment … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 3 · 5 Oct 2011 · 8,524 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Boundary Detection of Wall Motion in Two-dimensional Echocardiography ImagesFaten Abed Ali Dawood, Rahmita Wirza Rahmat, Mohd Zamrin Dimon et al.Problem statement: Medical image analysis is a particularly difficult problem because the inherent characteristics of these images, including low contrast, speckle noise, signal dropouts and complex anatomical structures. An accurate analysis of wall motion in Two-dimensional echocardiography images is “important clinical diagnosis parameter for many cardiovascular diseases”. A challenge most researchers faced is how to speed up the clinical decisions … …Journal of Computer Science, Vol. 7, Issue 8 · 15 Jul 2011 · 8,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractAccurate Determination of Nonlinear Refractive Index for Some Binary Glass SystemsElSayed MoustafaProblem statement: This study investigates the relation between the nonlinear optical susceptibility (χ(3)) and the ratio (α1/αo-2), then the nonlinear index determination for some binary glass systems. Recently suitable relationship between the oxidation polarizability and the nonlinear optical properties was established for simple oxides glasses. So in this study more attention and investigation is paid to the trend of that … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of Gamma irradiation in treatment of Waste Activated Sludge to Obtain Class a BiosolidsMohammed I. AL-Ghonaiem, Abdelnasser Salah Shebl Ibrahim, Ali Abdullah Al-SalamahProblem statement: The main objective of the current study was investigation of the possible application of Gamma irradiation for treatment of the activated sludge generated wastewater treatment stations, to achieve the standard requirements in term of pathogens content. Approach: Activated sludge samples were collected from Riyadh wastewater plant and analyzed quantitatively for the presence of important bacterial parameters including fecal … …American Journal of Environmental Sciences, Vol. 6, Issue 6 · 31 Dec 2010 · 7,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of an Educational Scenario Exercise on Participants' Competencies of Systemic ThinkingSimon BurandtProblem statement: Education for sustainable development (ESD) aims to shape key competencies of individuals and therefore needs methods to enable learners to acquire these competencies. Systemic thinking can be regarded as a meta-competency in ESD, because it contains many important aspects found in most key competencies of ESD. Scenario analysis is described as a learning environment that fosters the acquisition … …Journal of Social Sciences, Vol. 7, Issue 1 · 18 Dec 2010 · 8,741 accessesView PDFCite
