Research ArticleOpen accessAll words, across the recordDetection of Subsurface Defects in Concrete Bridge Deck JointsWonchang Choi, Larry Rickard, Taher Abu-Lebdeh, Miguel PicornellProblem statement: The integrity of deck joints in highway bridges plays a major role to determine overall performance of bridge system. As the bridge maintenance program, the defects in deck joints have historically been detected by conventional non-destructive testing and evaluation methods such as visual inspection, chain-dragging and by the detecting sounds under the traffic. Future bridge maintenance challenges will … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 4 · 31 Dec 2011 · 7,777 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDetection of Aberrant Data Points for an effective Effort Estimation using an Enhanced Algorithm with Adaptive FeaturesS. Malathi, S. SridharProblem statement: The spiraling growth of IT industry has witnessed an unprecedented change in the software development paradigm, from algorithmic models to machine learning techniques. At present, there are no standard methods to predict the accuracy of software cost estimation, which is an important goal of the software community. Approach: This study proposes a simple and systematic algorithmic procedure for … …Journal of Computer Science, Vol. 8, Issue 2 · 21 Nov 2011 · 7,095 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAnalysis of Diffusion Coefficient using Reversed-Flow Gas Chromatography-A ReviewKhalisanni Khalid, Rashid Atta Khan, Sharifuddin Mohd. ZainProblem statement: Since the earliest publication on the technique, Reversed-Flow Gas Chromatography (RF-GC) has been used to determine physicochemical properties by measuring the value of one in the presence of another. The method is precise, accurate and simple compared to other conventional techniques. Approach: The experimental setup consists of a small modification of a commercial gas chromatograph, so that it … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 7,227 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordAn Alternative Ray Tracing Algorithm for Understanding Scenes with Embedded ObjectsNancy Dandachy, Dimitri Plemenos, Safwan Chendeb, Bachar El HassanProblem statement: In the virtual world domain, the existing techniques of exploration, were not able alone to resolve the understanding problem of scenes with embedded object, also they are time and memory consuming. As a solution, a novel method that enhances the visualization of 3D ray traced scenes with embedded objects by creating a hole proportional to its interior parts … …Journal of Computer Science, Vol. 6, Issue 6 · 30 Jun 2010 · 7,294 accessesView PDF Cite
