Research ArticleOpen accessIn the abstractA Novel Approach to Medical Image SegmentationNandagopalan Shanmugam, Adiga B. Suryanarayana, Sudarshan TSB et al.Problem statement: Segmentation is a vital aspect of medical imaging. It aids in the visualization of medical data and diagnostics of various diseases. Ultrasound image segmentation, in particular echocardiographic image segmentation, is required to identify the regions of interest such as Left Ventricle (LV) and other cardiac cavities. Existing methods do not address the drawbacks of speed and quality of … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,214 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteractive Computing Framework for Engineering ApplicationsJovana Knezevic, Jerome Frisch, Ralf-Peter Mundani, Ernst RankProblem statement: Even though the computational steering state-of-the-art environments allow users to embed their simulation codes as a module for an interactive steering without the necessity for their own expertise in high-performance computing and visualisation, e.g., these environments are limited in their possible applications and mostly entail heavy code changes in order to integrate the existing code. Approach: In this … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,207 accessesView PDFCite
Research ArticleOpen accessIn the abstractProposing the new Algorithm and Technique Development for Integrating Web Table Extraction and Building a MashupRudy A.G. Gultom, Riri Fitri Sari, Bagio BudiardjoProblem statement: Nowadays, various types of data in web table can be easily extracted from the Internet, although not all of web tables are relevant to the users. As we may know, most web pages are in unstructured HTML format, making web table extraction process very time consuming and costly. HTML format only focuses on the presentation, not based on … …Journal of Computer Science, Vol. 7, Issue 2 · 25 Feb 2011 · 7,679 accessesView PDFCite
Research ArticleOpen accessIn the abstractPesticide-Tolerant Bacteria Isolated from Agricultural Canals in the Lower Rio Grande Valley of South TexasSandra Puente Aguirre, Kristine L. LoweAtrazine and oxamyl are commonly-used pesticides in the Lower Rio Grande Valley of South Texas. Problem statement: Pesticides may become environmental contaminants due to overuse, runoff and other mechanisms and may impact non-target organisms and ecosystems. Pesticides may be degraded by indigenous microorganisms or by abiotic means. In this study, waterborne bacteria from agricultural canals were examined to assess potential … …OnLine Journal of Biological Sciences, Vol. 10, Issue 3 · 30 Sep 2010 · 7,610 accessesView PDFCite
Research ArticleOpen accessIn the abstractWall Shear Stress Distribution in Patient Specific Coronary Artery BifurcationVahab Dehlaghi, Frank GijsenProblem statement: Atherogenesis is affected by hemodynamic parameters, such as wall shear stress and wall shear stress spatial gradient. These parameters are largely dependent on the geometry of arterial tree. Arterial bifurcations contain significant flow disturbances. Approach: The effects of branch angle and vessel diameter ratio at the bifurcations on the wall shear stress distribution in the coronary arterial tree … …American Journal of Applied Sciences, Vol. 7, Issue 9 · 30 Sep 2010 · 7,365 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptable User Interface Based on the Ecological Interface Design Concept for Multiple Robots Operating Works with UncertaintyHiroshi FurukawaProblem statement: When supervising a team of semi-autonomous robots, the operator’s task is not only the manipulation of each robot but also achievement of the top goal that is assigned to the entire team of humans and robots. The operators are demanded to comprehend highly complex states and make appropriate decisions in dynamic environment using the limited cognitive resources. The … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,196 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow (Un)biased are Airport Security Screening Procedures? A Social-Cognitive ExperimentPoornima Madhavan, Jeremy R. BrownProblem statement: This research examined the role that social-cognitive biases such as gender biases and racial biases play in decision making processes during the screening of carry-on luggage at airports. This research is unique in that no research so far has addressed the social-psychological underpinnings of airport security screening procedures. Approach: Participants (n = 36) performed a computer simulated task … …Current Research in Psychology, Vol. 1, Issue 1 · 30 Jun 2010 · 8,009 accessesView PDFCite
Research ArticleOpen accessIn the abstractFocusing of the Flow Capture for Local Exhaust Ventilation SystemsS. Y. Spotar, A. L. SorokinProblem statement: The extraction hoods commonly used as inlet element of the local ventilation systems exhibit limited emission capture over moderate distances from the source of the hazardous emissions. Proposed inclusion of a swirling peripheral jet was found to increase the effective length over which the extraction hood successfully captures harmful fumes. However information on a detailed pattern field of … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,329 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Extraction from Computer Acquired Images of a Given 3D Environment for Enhanced Computer Vision and its Applications in Kinematic Design of RobosK. SelvarajProblem statement: Literature review was mainly aiming at recognition of objects by the computer and to make explicit the information that is implicit in the attributes of 3D objects and their relative positioning in the 3D Environment (3DE) as seen in the 2D images. However quantitative estimate of position of objects in the 3DE in terms of their x, y … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of Airflow and Aerodynamic Forces Acting on a Rotating Turbine VentilatorA.S. Farahani, N.M. Adam, M.K.A. AriffinProblem statement: Rotating turbine ventilators were generally found in most countries. They were simple in structure, light in weight and cheap to install. It was quite surprising that, the aerodynamics of this common device had not been numerically examined and the design process of most of these ventilators had developed progressively through trial and error methods. Approach: This study was … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,711 accessesView PDFCite
