Research ArticleOpen accessIn the abstractAn Environmental Decision Support System Based on a Multidimensional PrototypeGeorgakellos Dimitrios, Macris AristomenisThe present study utilizes the principles and data provided by the Environmental Priority Strategies (EPS) methodology in order to create a multidimensional prototype, which intends to assist the damage assessment process in this kind of projects. The EPS system, based on Life Cycle Assessment (LCA) methodology, is developed to help designers and product developers in finding which one of two … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of RNA-DNA Duplex Base Triplets to Antisense DrugsJie Yang, Yao Leng, Ju BaoSixty-four sets of three-dimensional models of RNA-DNA duplex base triplets were constructed based on codons by homology modeling method using software InsightII on Indigo workstation, which should be helpful for the study of RNA-DNA annealing, the basis of nucleic acids interactions and some peculiar motifs for design antisense oligonucleotides. Our research result reveal that the energies (such as E, Ec, … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 2 · 30 Jun 2005 · 6,531 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncreasing the Strength of Standard Involute Gear Teeth with Novel Circular Root Fillet DesignV. Spitas, Th. Costopoulos, C. SpitasIn this study the idea of spur gear teeth with circular instead of the standard trochoidal root fillet is introduced and investigated numerically using BEM. The strength of these new teeth is studied in comparison with the standard design by discretizing the tooth boundary using isoparametric Boundary Elements. In order to facilitate the analysis the teeth are treated as non-dimensional … …American Journal of Applied Sciences, Vol. 2, Issue 6 · 30 Jun 2005 · 7,586 accessesView PDFCite

Research ArticleOpen accessIn the abstractA Note on the Role of Abstraction and Generality in Software DevelopmentPavol Návrat, Roman FilkornAlthough the evolving field of software engineering introduces many methods and modelling techniques, we conjecture that the concepts of abstraction and generality are among the fundamentals of each such methodology. This study proposed a formal representation of these two concepts, along with a two-dimensional space for the representation of their application. Based on the examples, we further elaborate and discuss … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,972 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Field Development Scheduling, East Unity Oil Field, SudanTagwa A. Musa, Ahmed A.E. Ibrahin, Guan ZhenLiang, Fei QiIn order to improve the reservoir performance in East Unity oil field Sudan, the studies focused on characterization, modeling and simulation of the actual performance and future development. A model was constructed using a three-phase, three dimensional, black oil simulator (ECLIPSE). In this study a data from East Unity oil field Sudan started production at July 1999 was used to … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,157 accessesView PDFCite
