Research ArticleOpen accessIn the abstractA HYBRID FIREFLY ALGORITHM WITH FUZZY-C MEAN ALGORITHM FOR MRI BRAIN SEGMENTATIONMutasem K. AlsmadiImage processing is one of the essential tasks to extract suspicious region and robust features from the Magnetic Resonance Imaging (MRI). A numbers of the segmentation algorithms were developed in order to satisfy and increasing the accuracy of brain tumor detection. In the medical image processing brain image segmentation is considered as a complex and challenging part. Fuzzy c-means is … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 10 Sep 2014 · 8,074 accessesView PDFCite
Research ArticleOpen accessIn the abstractMEDICAL IMAGE SEGMENTATION FOR ANATOMICAL KNOWLEDGE EXTRACTIONMs Maya Eapen, Reeba KorahComputed Tomography-Angiography (CTA) images of the abdomen, followed by precise segmentation and subsequent computation of shape based features of liver play an important role in hepatic surgery, patient/donor diagnosis during liver transplantation and at various treatment stages. Nevertheless, the issues like intensity similarity and Partial Volume Effect (PVE) between the neighboring organs; left the task of liver segmentation critical. The … …Journal of Computer Science, Vol. 10, Issue 7 · 22 Feb 2014 · 6,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPLEMENTATION AND EVALUATION OF IMAGE PROCESSING TECHNIQUES ON A VISION NAVIGATION LINE FOLLOWER ROBOTWalaa E. Elhady, Heba A. Elnemr, Gamal SelimIn a fast growing industrial world, carriers are required to carry products from one manufacturing plant to another which are usually in different buildings or separate blocks. This study intends to automate this sector using vision controlled mobile robots instead of laying railway tracks which are both expensive and inconvenient. To achieve this purpose an autonomous robot with computer vision … …Journal of Computer Science, Vol. 10, Issue 6 · 1 Feb 2014 · 7,746 accessesView PDFCite
Research ArticleOpen accessIn the abstractDeveloping Inner Peace and Joy through Art EducationSusmita LakhyaniProblem statement: Art Education has been given place in the curriculum yet there is a general misconception that the subject Art is of lesser importance and treated as a mere entertaining fringe. The present study looks into this matter. The basic key question, therefore, is-Does process of art education that is art instruction, promotes creative aspects of students and develops … …Journal of Social Sciences, Vol. 8, Issue 2 · 18 Feb 2012 · 11,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Influence of Parents in Adolescents' MisbehaviorHabibah Elias, Nooreen NoordinPositive relationships within the family, parental support, a consistent and constructive parental discipline style and adult supervision tend to be related negatively to adolescents deviant behaviors and their associations with deviant peers. Poor family relationships were found to be associated with higher levels of delinquent behaviors, possibly due to the fact that parents in those families provided poor role models … …Journal of Social Sciences, Vol. 7, Issue 3 · 18 Jul 2011 · 8,384 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 · 8,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproved Dielectric Model for Polyvinyl Alcohol-Water Hydrogel at Microwave FrequenciesYou Kok Yeow, Zulkifly Abbas, Kaida Khalid, Mohamad Zaki Abdul RahmanProblem statement: The study described rigorous dielectric modeling for Polyvinyl Alcohol (PVA)-water hydrogel mixture at microwave frequencies. Approach: A commercial open-ended coaxial sensor was used to measure the dielectric constant, loss factor and ionic conductivity, σ of PVA-water hydrogel mixture ranging concentration of 80-100% water content. Results: The sensor was operating between 0.13 and 20 GHz at and above of … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,045 accessesView PDFCite
