Research ArticleOpen accessEvery word in the titleInformation Systems Development Knowledge Sharing-Organizational Justice, Physical Distance and Social InterdependenceMarzanah A. Jabar, Cheah Chee Yeong, Fatimah SidiProblem statement: Knowledge hoarding in Requirements Elicitation (RE) phase could lead to Information Systems Development (ISD) project failure. Many researchers have discussed important factors in knowledge sharing. Nevertheless, the success rate for ISD projects is low and there are other major factors for consideration. Approach: Review was conducted to identify potential gaps in existing literature and to explore new factors … …Journal of Computer Science, Vol. 8, Issue 1 · 26 Oct 2011 · 7,247 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Sense of Progression and Cognitive Distance on Path Choice and Walking Behavior While Aiming To Reach DestinationMohammad Paydar, Samira RamezaniProblem statement: Studies focused on walking behavior have indicated the relationship of different factors of built environment with walking to reach destination and walking for recreation. Furthermore, according to literature on path choice behavior, there is a relationship between walking behavior and path choice of pedestrians. Empirical studies on path choice behavior have also shown that the effects of different … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 3 · 30 Sep 2010 · 8,162 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Distance Measurement Between Stereo Vision and Ultrasonic SensorSurachai PanichProblem statement: The traditional approaches in mobile robot research are the use of stereo vision systems to extract range information from pairs of images. One of the difficulties of techniques in navigation is that the intrinsic computational expense of extracting three dimensional information from stereo pairs of images. Approach: To compare performance sensor readings from environment between stereo vision and … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,244 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenomic Distance between Thymidylate Synthase and Dihydrofolate Reductase Genes Does Not Correlate With Phylogenetic Evolution in BacteriaVitor Hugo MoreauProblem statement: Dihydrofolate Reductase (DHFR) and Thymidylate Synthase (TS) exist as bifunctional enzymes coded into unique polypeptide chain in protozoans. Bifunctional DHFR-TS is associated with an increase in the enzymatic activity by channeling the substrate between the active sites. In some bacteria, DHFR and TS genes are neighbors in the genome, whereas in others, they are located millions of base … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 1 · 31 Mar 2010 · 8,188 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison of Exact Algorithms for Rectilinear Distance Single-Source Capacitated Multi-Facility Weber ProblemsChansiri Singhtaun, Peerayuth CharnsethikulProblem statement: The objective of this study is to develop efficient exact algorithms for a single source capacitated multi-facility location problem with rectilinear distance. This problem is concerned with locating m capacitated facilities in the two dimensional plane to satisfy the demand of n customers with minimum total transportation cost which is proportional to the rectilinear distance between the facilities … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Feb 2010 · 7,524 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA New Distance Based Route Maintenance Strategy for Dynamic Source Routing ProtocolMuhammad F. Sjaugi, Mohamed Othman, Mohd. Fadlee A. RasidAlthough DSR can respond a route quickly, it yields a long delay when a route is rebuilt. This is because when source node receives RERR packet, it will try to find alternative routes from the route cache. If alternative routes are not available, the source node, then, will enter route discovery phase to find new routes. We introduced a new … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 8,314 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Swarm-based Distance Vector Routing to Support Multiple Quality of Service (QoS) Metrics in Mobile Adhoc NetworksR. Asokan, A. M. Natarajan, A. NivethaQuality of Service support for Mobile Ad-hoc Networks is a challenging task due to dynamic topology and limited resource. The main purpose of QoS routing is to find a feasible path that has sufficient resources to satisfy the constraints. A fundamental problem in QoS routing is to find a path between a source and destination that satisfies two or more … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,665 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Distance of the Submerged Vanes from the Outer Bank on Sediment Movement within 180° BendJaafar S. Maatooq, Barq A. AdhabA small aspect ratio of submerged vanes when used near the outer bank at the angle of attack between 10° to 20° and at the initial height above the bed between 20-40% of flow depth is considered one of the most successful river training structures. Vanes when located within the bends of river, produces helical swirls at inverse action with … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 3 · 3 Jul 2017 · 7,474 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNormalized Web Distance Based Web Query ClassificationS. Lovelyn Rose, K. R. ChandranProblem statement: The problem is to classify a given web query to a set of 67 target categories. The target categories are ranked based on the degree of similarity to a given query. Approach: The feature set is the set of intermediate categories retrieved from a directory search engine for a given query. Using direct mapping and Normalized Web Distance … …Journal of Computer Science, Vol. 8, Issue 5 · 9 Mar 2012 · 6,589 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleShape Retrieval through Angular Distance with Shortest Augmenting Path AlgorithmD. Chitra, N. Devarajan, T. ManigandanProblem statement: The shape of an object is very important in object recognition. Shape matching is a challenging problem, especially when articulation and deformation of a part occurs. These variations may be insignificant for human recognition but often cause a matching algorithm to give results that are inconsistent with our perception. Approach: We proposed a customized approach to measure similarity … …Journal of Computer Science, Vol. 7, Issue 12 · 21 Oct 2011 · 6,817 accessesView PDFCite
