Research ArticleOpen accessIn the abstractA Control-Oriented Coverage Metric and its Evaluation for Hardware DesignsShireesh Verma, Kiran Ramineni, Ian G. HarrisProblem statement: Dynamic verification, the use of simulation to determine design correctness, is widely used due to its tractability for large hardware designs. A serious limitation of dynamic techniques is the difficulty in determining whether or not a test sequence is sufficient to detect all likely design errors. Coverage metrics are used to address this problem by providing a set … …Journal of Computer Science, Vol. 5, Issue 4 · 30 Apr 2009 · 7,531 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeveling Process of Total Electron Content (TEC) Using Malaysian Global Positioning System (GPS) DataY. Norsuzila, M. Abdullah, M. IsmailThe signals from the satellites of the Navstar Global Positioning System (GPS) travel through the earth's ionosphere on their way to GPS receivers. However, ionospheric delay is one of the main sources of error in GPS. The magnitude of the ionospheric delay is influenced by the Total Electron Content (TEC) along the radio wave path from a GPS satellite to … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 3 · 30 Sep 2008 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Twelve Dielectric Moisture Probes for Soil Water Measurement under Saline ConditionsM. Inoue, B.A. Ould Ahmed, T. Saito, M. IrshadRecently the research on the determination of soil water content and electrical conductivity using automated technique has received tremendous attention. Selecting the type of system that should be used for soil water measurement under saline conditions depends on its precision. A laboratory study was carried out to measure the soil water content (θ) and soil solution electrical conductivity (ECw) using … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractRice Grain Moisture Determination Using Microstrip Wide-Ring and Microstrip Coupled-Line SensorsHou Kit Mun, Kok Yeow You, Mohamad Ngasri DimonDetermining the Moisture Content (MC) inside rice grain is an important element for grain processesing such as harvesting, storage, quality control and transportation. A microstrip wide-ring sensor and a microstrip coupled-line sensor with low insertion loss were developed to operate at relatively low frequency to determine the MC and relative complex permittivity of rice grain. The complex permittivity for rice … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 3 Apr 2015 · 7,443 accessesView PDFCite
Research ArticleOpen accessIn the abstractSwarm Optimization Techniques for Segmenting Gel Electrophoresis ImagesSara Ibrahim Ibrahim, Mohamed Abd Allah Makhlouf, Ghada.S. El-Tawel, M.E. WahedGel Electrophoresis (GE) are discussed as the main tool to dissociate DNA sequences. It helps in analyzing the genome such that each image resulting from it consists of lanes that include several bands. Image segmentation plays the foremost role in image processing. It helps in producing accurate results in medical diagnosis. Image segmentation works by dividing an image into regions … …Current Research in Bioinformatics, Vol. 5, Issue 1 · 18 Jun 2016 · 8,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractA VISION-BASED TRAVELLED DISTANCE ESTIMATION ALGORITHM IN AN INDOOR ENVIRONMENT USING A MOBILE ROBOTMamadou Diop, Chot Hun Lim, Tien Sze Lim, Lee-Yeng OngAutonomous navigation for a mobile robot still remains as a challenging area to be explored. In an indoor environment, while GPS is unavailable and wheel encoder suffer from error accumulation due to wheel slips, vision-based travelled distance estimation can be considered as an alternative approach for more accurate measurements. This study presents a new algorithm to estimate travelled distance of … …Journal of Computer Science, Vol. 10, Issue 12 · 26 Dec 2014 · 8,703 accessesView PDFCite
Research ArticleOpen accessIn the abstractRELIABILITY OF THE GERMAN LANGUAGE VERSION OF THE PRESCHOOL AND KINDERGARTEN BEHAVIOR SCALES SECOND EDITIONAida Al Awmleh, Alexander WollThe purpose of this study was to examine the reliability and validity of the English and German language versions of the behavior rating scale, Preschool and Kindergarten Behavior Scales, Second Edition (PKBS-2) and make a comparison between them. Data were collected from (37) preschool-age children using both the English and German versions. Internal consistency, testing and retesting, alternate [language] versions … …Journal of Social Sciences, Vol. 9, Issue 2 · 20 Aug 2013 · 8,149 accessesView PDFCite
Research ArticleOpen accessIn the abstractHuman Face Detection and Recognition using Web-CamPetcharat Pattanasethanon, Charuay SavithiProblem statement: The illuminance insensitivity that reflects the angle of human facial aspects occurs once the distance between the object and the camera is too different such as animated images. This has been a problem for facial recognition system for decades. Approach: For this reason, our study represents a novel technique for facial recognition through the implementation of Successes Mean … …Journal of Computer Science, Vol. 8, Issue 9 · 17 Aug 2012 · 8,275 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 abstractSummarizing Relational Data Using Semi-Supervised Genetic Algorithm-Based Clustering TechniquesRayner AlfredProblem statement: In solving a classification problem in relational data mining, traditional methods, for example, the C4.5 and its variants, usually require data transformations from datasets stored in multiple tables into a single table. Unfortunately, we may loss some information when we join tables with a high degree of one-to-many association. Therefore, data transformation becomes a tedious trial-and-error work and … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,588 accessesView PDFCite
