Research ArticleOpen accessIn the abstractIMPLEMENTATION AND EVALUATION OF IMAGE PROCESSING TECHNIQUES ON A VISION NAVIGATION LINE FOLLOWER ROBOTWalaa E. Elhady, Heba A. Elnemr, Gamal SelimIn a fast growing industrial world, carriers are required to carry products from one manufacturing plant to another which are usually in different buildings or separate blocks. This study intends to automate this sector using vision controlled mobile robots instead of laying railway tracks which are both expensive and inconvenient. To achieve this purpose an autonomous robot with computer vision … …Journal of Computer Science, Vol. 10, Issue 6 · 1 Feb 2014 · 7,749 accessesView PDFCite
Research ArticleOpen accessIn the abstractPrediction of Days After Anthesis of Developing Tomato (Solanum lycopersicum) Fruit from Blossom-End Changes in ColorTiznado-Hernández Martín Ernesto, Delia Moreno-Velázquez, Angel Javier Ojeda-Contreras, Andrés Ochoa-MezaThe development of mathematical models to predict the physiological status of a developing fruit can be a useful tool to reduce the variation in fruit response to postharvest treatments. The objective of this study was to develop a mathematical model to predict Days After Anthesis (DAA) in tomato fruit from changes in the blossom end color. Around 160 tomato flowers … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 4 Sep 2013 · 8,107 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Algorithm for Mining Spatially Co-located Moving ObjectsG. Manikandan, S. SrinivasanMining co-location patterns from spatial databases may disclose the types of spatial features which are likely located as neighbors’ in space. Accordingly, we present an algorithm previously for mining spatially co-located moving objects using spatial data mining techniques and Prim’s Algorithm. In the previous technique, the scanning of database to mine the spatial co-location patterns took much computational cost. In … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 2 Mar 2013 · 6,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractEr3+-Doped Soda-Lime Silicate Glass: Artificial Pink GemstonePichet Limsuwan, Kheamrutai Thamaphat, Jakrapong Kaewkhao, Weeranut KaewwisetEr3+-doped soda-lime silicate glasses of the composition (in mol%) (65-x)SiO2:25Na2O:10CaO:xEr2O3 (where x = 0, 1, 2, 3, 4 and 5) were fabricated by conventional melt quenching technique. The physical and optical properties were measured and investigated. The erbium oxide enters the glass network as a modifier by occupying the interstitial space in the network and generating the NBOs to the … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 29 Aug 2012 · 7,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability and Ergonomic Design Features of Tractor Mounted Hydraulic Elevator for Coconut HarvestingKishor Purushottamrao Kolhe, Ashok G. Powar, Amit D. Dhakane, Sham H. MankarProblem statement: The most important design criterion of mechanized device was safety; safety comprises both the safety of operator and safety of maintenance personnel. Failures and safety of harvesting platform of Tractor Mounted Hydraulic Elevator (TMHE) powered by tractor PTO was tested by finite element method for the mechanical harvesting of coconut orchards using digital ergonomic hart rate meter. The … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 20 Sep 2011 · 8,335 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Performance of Multivariate Bernoulli Model based Documents Clustering Algorithms using Transformation TechniquesPerumal Pitchandi, Nedunchezhian RajuProblem statement: Document clustering is the most important areas of data mining since they are very much and currently the subject of significant global research since such areas strengthen the enterprises of web intelligence, web mining, web search engine design and so forth. Generative models based on the multivariate Bernoulli and multinomial distributions have been widely used for text classification. … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the abstractSynthesis and Characterization of Silver/Clay Nanocomposites by Chemical Reduction MethodMansor Bin Ahmad, Kamyar Shameli, Majid Darroudi et al.Problem statement: Silver Nanoparticles (Ag-NPs) have been synthesized by using chemical reduction method into the interlayer space of a Montmorillonite (MMT) as a solid support which is used to antibacterial application and polymer nanocomposites for fabrication of medical devices. Approach: AgNO3 and NaBH4 were used as a silver precursor and reducing agent, respectively. The properties of Ag/MMT nanocomposites were studied … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 8,175 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecure Antnet Routing Algorithm for Scalable Adhoc Networks Using Elliptic Curve CryptographyV. Vijayalakshmi, T. G. PalaniveluThe secure end-to-end route discovery in the decentralized Mobile Adhoc Networks (MANETs) should have to meet the requirements of prevention of DoS attacks on data traffic, should be adaptive and fault tolerant and must have high speed, low energy overhead and scalability for future development. In this research a secure routing using antnet mechanism and mutual authentication using Elliptic Curve … …Journal of Computer Science, Vol. 3, Issue 12 · 31 Dec 2007 · 6,959 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Cell-Responsive Nanophase Hydroxyapatite for Tissue EngineeringR. Murugan, S. RamakrishnaScaffold plays a critical role in engineering bone tissues by providing necessary structural support for the cells to accommodate and guiding their growth in the three dimensional (3D) space. Therefore, designing scaffold that mimic composition and structural aspects of the bone is of great importance to promote cell adhesion, cell-matrix interactions, osteointegration, tissue formation and continued function. Nanophase hydroxyapatite (HA) … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,168 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Variable Neighborhood Search Algorithm for Assigning Cells to Switches in Wireless NetworksMatthieu Andr, Gilles Pesant, Samuel PierreThe problem of assigning cells to switches in wireless networks consists of minimizing the total operating cost, that is, the cost of linking cells to switches and the cost of handover from one cell to another, by taking into account factors such as network topology, switch capacity and traffic load in the entire network. Such a problem is well known … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,753 accessesView PDFCite
