Research ArticleOpen accessIn the abstractSpeech Compression for Noise-Corrupted Thai Expressive SpeechSuphattharachai ChomphanProblem statement: In speech communication, speech coding aims at preserving the speech quality with lower coding bitrate. When considering the communication environment, various types of noises deteriorates the speech quality. The expressive speech with different speaking styles may cause different speech quality with the same coding method. Approach: This research proposed a study of speech compression for noise-corrupted Thai expressive … …Journal of Computer Science, Vol. 7, Issue 10 · 6 Aug 2011 · 6,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractLogo Recognition System Using Angular Radial Transform DescriptorsOmar Mohammed Wahdan, Khairuddin Omar, Mohammad Faidzul NasrudinProblem statement: The shape-based logo recognition systems have been developed to automate the logo registration process. The logo recognition operation faces many challenges such as having to recognize logos that might be scaled, rotated, translated and added with noises. Different types of logo’s shapes further add to the complex nature of this problem. Approach: We developed a logo recognition system … …Journal of Computer Science, Vol. 7, Issue 9 · 26 Jul 2011 · 7,200 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Exploration Using a Three-Axis Tactile Sensing InformationS. C. Abdullah, Jiro Wada, Masahiro Ohka, Hanafiah YussofProblem statement: To advance the robust object recognition of robots, we present an algorithm for object exploration based on three-axis tactile data that is necessary and sufficient for the evaluation of contact phenomena. Approach: The object surface contour is acquired by controlling the finger position so that the normal force, measured by optical three-axis tactile sensors, remains constant as two … …Journal of Computer Science, Vol. 7, Issue 4 · 4 Apr 2011 · 7,318 accessesView PDFCite
Research ArticleOpen accessIn the abstractOccupational Stress and Family Difficulties of Working WomenMaryam Zarra-Nezhad, Ali Moazami-Goodarzi, Leila Hasannejad, Khadijeh RoushaniProblem statement: Work and family are the two most important aspects in women’s lives. Balancing work and family roles has become a key personal and family issue for many societies. There are many facets in working mother’s lives that subject to stresses. They deal with home and family issues as well as job stress on a daily basis. Imbalance between … …Current Research in Psychology, Vol. 1, Issue 2 · 31 Dec 2010 · 16,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractParallel Approach for Content Based Medical Image Retrieval SystemM. Emmanuel, D.R. Ramesh Babu, Jayashree Jagdale et al.Problem statement: Parallel implementation of a CBIR system for medical applications due to the rapid progress in the technologies for obtaining and storing digital images for diagnostic purposes in medicine. Approach: For feature extraction Wavelet decomposition was used for texture, global color histograms for color and novel wavelet based approach for shape feature extraction. The system had been implemented in … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 7,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractProgrammable System on Chip Distributed Communication and Control Approach for Human Adaptive Mechanical SystemAhmad ‘Athif Mohd Faudzi, Koichi SuzumoriProblem statement: Communication and control are two main components in any Mechatronics system. They can be designed either by centralized or decentralized approach. Both approaches can be chosen based on application designed and specific requirements of the designer. In this study, decentralized or normally called distributed approach was selected to solved communication and control of a human adaptive mechanical system … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 6,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Fuzzy Knowledge Based Controller for Autonomous Robot Motion ControlMbaitiga ZacharieProblem statement: Research into robot motion control offers research opportunities that will change scientists and engineers for year to come. Autonomous robots are increasingly evident in many aspects of industry and everyday life and a robust robot motion control can be used for homeland security and many consumer applications. This study discussed the adaptive fuzzy knowledge based controller for robot … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 6,912 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimizing Feature Construction Process for Dynamic Aggregation of Relational AttributesRayner AlfredProblem statement: The importance of input representation has been recognized already in machine learning. Feature construction is one of the methods used to generate relevant features for learning data. This study addressed the question whether or not the descriptive accuracy of the DARA algorithm benefits from the feature construction process. In other words, this paper discusses the application of genetic … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,935 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Seismic Active Earth Pressure Using Curved Failure Surface with Localized StrainHemanta HazarikaProblem statement: Correct evaluation of the earth pressure against retaining structure during earthquake is essential for the safe and economic design of geotechnical structures. Progressive deformation in the backfill and the assumed shape of failure wedge affect the calculated values of seismic earth pressures. However, no research until now is available that considers both of these two factors in an … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 3 · 30 Sep 2009 · 7,550 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent OkiKoSenPBX1 Security Patrol Robot via Network and Map-Based Route PlanningMbaïtiga ZacharieProblem statement: With an increased demand for security and limited numbers of trained security personnel, some security mangers have a lot of ground to police and limited staff to cover it. To compensate for shortages of security staff and to reduce the stress of security managers, we have developed an intelligent patrol robot system called "OkiKoSenPBX1". The system integrates a … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,418 accessesView PDFCite
