Research ArticleOpen accessIn the abstractProteomics Approach for Investigating the Disease Resistance Using Cucumber as Model PlantSaligrama A. Deepak, Junko Shibato, Hideo Ishii et al.The profile of proteins induced in cucumber leaves pretreated with Acibenzolar-S-Methyl (ASM) and challenge inoculated with Colletotrichum orbiculare are presented. ASM was applied to the first leaf and the third leaf collected at different time intervals of 0-48 h and the total protein extracted using trichloroacetic acid acetone was analyzed by two-dimensional gel electrophoresis. Increased expressions of pyridoxine biosynthesis protein, … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 3 · 30 Sep 2008 · 7,243 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Minimal Duration Essential for Isolation of Humic Acids From Soils in Forest Restoration ProgrammesMohd Ramzan Nur Hanisah, Osumanu Haruna Ahmed, Kasim Susilawati et al.This study was conducted to investigate whether a simple and rapid method could be developed for extracting, fractionating and purifying soil HA in forest rehabilitation programmes. Humic acids from 10 g of soil were extracted with 100 mL of 0.10 M NaOH. Different extraction periods (4, 8, 12, 16, 20 and 24 h) were tested. Samples were centrifuged (16,211 G … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractGraph Based Segmentation in Content Based Image RetrievalP. S. Suhasini, K. S.R. Krishna, I. V.M. KrishnaProblem statement: Traditional image retrieval systems are content based image retrieval systems which rely on low-level features for indexing and retrieval of images. CBIR systems fail to meet user expectations because of the gap between the low level features used by such systems and the high level perception of images by humans. To meet the requirement as a preprocessing step … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractToxicity of Reference Sediment SamplesK. R. Beg, S. AliThis study was done to determine toxicity of certified reference sediment to be used for quality assurance in sediment toxicity testing program. Certified Reference Harbor Sediment (HS-4B for PAHs) and Estuarine Sediment (LGC-6137 for Trace Metals) were procured commercially from LGC Company, UK, and repeatedly analyzed against solid phase Microtox toxicity assay to determine EC50 values. Both PAHs rich and … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 6,722 accessesView PDFCite
Research ArticleOpen accessIn the abstractAbdominal and Thoracic Aortic Aneurysm ModelingMona Abdolrazaghi, Mehdi NavidBakhsh, Kamran HassaniModeling is a beneficial tool for understanding cardiovascular system functioning and pathophysiology of the system. The present study is concerned with left ventricle Pressure-Volume diagrams obtained by modeling of aortic aneurysms using the cardiovascular electronic system. In addition, these graphs were compared with a normal condition. The electrical circuit of the cardiovascular system consists of 42 segments including the main … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,611 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Empirical Validation of Object-Oriented Design Metrics for Fault PredictionJie Xu, Danny Ho, Luiz F. CapretzProblem Statement: Object-oriented design has become a dominant method in software industry and many design metrics of object-oriented programs have been proposed for quality prediction, but there is no well-accepted statement on how significant those metrics are. In this study, empirical analysis is carried out to validate object-oriented design metrics for defects estimation. Approach: The Chidamber and Kemerer metrics suite … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,992 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Model Reference Adaptive Controller Based-On Neural-Fuzzy Techniques for Nonlinear Dynamical SystemsHafizah Husain, Marzuki Khalid, Rubiyah YusofThis paper presents a direct neural-fuzzy-based Model Reference Adaptive Controller (MRAC) for nonlinear dynamical systems with unknown parameters. The two-phase learning is implemented to perform structure identification and parameter estimation for the controller. In the first phase, similarity index-based fuzzy c-means clustering technique extracts the fuzzy rules in the premise part for the neural-fuzzy controller. This technique enables the recruitment … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the abstractMining Functional Dependency from Relational Databases Using Equivalent Classes and Minimal CoverJalal Atoum, Dojanah Bader, Arafat AwajanData Mining (DM) represents the process of extracting interesting and previously unknown knowledge from data. This study proposes a new algorithm called FD_Discover for discovering Functional Dependencies (FDs) from databases. This algorithm employs some concepts from relational databases design theory specifically the concepts of equivalences and the minimal cover. It has resulted in large improvement in performance in comparison with … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractPitch Angle Control of Variable Speed Wind TurbineYousif El-TousThe aim of this study is to design a simple controller to maximize the extracted energy of wind turbines. In this study the pitch angle control of variable speed wind turbine is investigated. In particular, it concentrates on the extraction of maximum available energy, reduction of torque and output power variations, which gives stresses in the gearbox and mechanical structure. … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 8,740 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhancing P300 Component by Spectral Power Ratio Principal Components for a Single Trial Brain-Computer InterfaceS. Andrews, Ramaswamy Palaniappan, Andrew Teoh, Loo chu KiongHere we present a novel approach to detect P300 wave in single trial Visual Event Related Potential (VERP) signals using improved principal component analysis to enable a faster brain-computer interface (BCI) design. In the process, the principal components (PCs) are selected using novel methods, namely spectral power ratio (SPR) and sandwich spectral power ratio (SSPR). We set out to assess … …American Journal of Applied Sciences, Vol. 5, Issue 6 · 30 Jun 2008 · 7,884 accessesView PDFCite
