Research ArticleOpen accessIn the abstractA Block Cipher Algorithm for Multimedia Content Protection with Random Substitution using Binary Tree TraversalP. Vidhya Saraswathi, M. VenkatesuluMany people consume multimedia content (images, music, movie) on portable devices like DVD player, MP3 player, Portable Multimedia Player and also through Internet. Problem statement: The conventional algorithms such as DES and AES cannot be used directly in multimedia data, since multimedia data are repeatedly have high redundancy, large-volumes and require real-time operations, such as displaying, cutting, copying, bit-rate conversion … …Journal of Computer Science, Vol. 8, Issue 9 · 15 Aug 2012 · 7,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Large Capacity Endplate Steel ConnectionsMohamed Eldemerdash, Taher Abu-Lebdeh, Moayyad Al NasraProblem statement: Extended endplate connection is one of the most widely used beam-to column steel connections because of its fabrication simplicity, good overall performance and cost effectiveness compared with other connection types. The objective of this research is to develop three-dimensional finite element models to study the behavior of large capacity eight-bolt extended un-stiffened wide endplate steel connections, using current-technology … …Journal of Computer Science, Vol. 8, Issue 4 · 28 Jan 2012 · 6,912 accessesView PDFCite

Research ArticleOpen accessIn the abstractThe Effect of Air Entry Values on Hysteresis of Water Retention Curve in Saline SoilS. Konyai, V. Sriboonlue, V. Trelo-GesProblem statement: The saline soil in Northeast Thailand is caused by saline groundwater rise in unsaturated zone to accumulate as salt at soil surface. Approach: This problem had been exacerbated in the last few decades by human activities e.g., deforestation and salt mining. This salinity problem can be solved by capillary rise control of saline groundwater flow. Results: The soil … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,937 accessesView PDFCite

Research ArticleOpen accessIn the abstractFeature Selection in Data-Mining for Genetics Using Genetic AlgorithmV. N. Rajavarman, S. P. RajagopalanWe discovered genetic features and environmental factors which were involved in multifactorial diseases. To exploit the massive data obtained from the experiments conducted at the General Hospital, Chennai, data mining tools were required and we proposed a 2-Phase approach using a specific genetic algorithm. This heuristic approach had been chosen as the number of features to consider was large (upto … …Journal of Computer Science, Vol. 3, Issue 9 · 30 Sep 2007 · 6,627 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Physical Refining on Palm Vitamin E (Tocopherol, Tocotrienol and Tocomonoenol)Chiew Wei Puah, Yuen May Choo, Ah Ngan Ma, Cheng Hock ChuahThis study reports the effect of physical refining on palm vitamin E including α- tocopherol, α-, γ and α-tocotrienols as well as α- tocomonoenol. A method using HPLC with fluorescence detector using normal phase silica column is described. An isocratic elution with n-hexane/THF/2-propanol (1000:60:4, by vol.) as mobile phase was used. The structure of the α- tocomonoenol was determined using … …American Journal of Applied Sciences, Vol. 4, Issue 6 · 30 Jun 2007 · 8,362 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum CelluloseA. Rezaee, J. Derayat, S. B. Mortazavi et al.In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function of pH, adsorbent dose and contact time. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 8,283 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUncertainty Assessment for the Buckling Analysis of Glass Columns with Random ParametersMohammad Momeni, Chiara BedonLoad-bearing elements composed of glass, as known, are often susceptible to buckling collapse mechanisms. This intrinsic characteristic (and thus potential limitation for design) typically derives from the use of relatively small thicknesses to cover large spans and surfaces, thus resulting in a multitude of columns, beams, or plates that are characterized by high slenderness. In the literature, accordingly, several and … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 22 Dec 2020 · 6,295 accessesView PDFCite
