Research ArticleOpen accessIn the abstractEco-Efficient Product Design Using Theory of Inventive Problem Solving (TRIZ) PrinciplesIssac Lim Sing Sheng, Teoh Kok-SooProblem statement: In recent years, much attention has been focused on the eco-efficiency of product development. The majority of environmental decisions are only made in the later stages of product development where not much modification can be done. To produce eco-efficient products, environmental decisions ought to be considered in the early stages of product development. With the demand of developing … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 11,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedded Systems Education for Multiple DisciplinesAli H. El-Mousa, Ashraf Al-SuyyaghProblem statement: This study described the process and experience of designing and developing an embedded systems first course that serves different disciplines at the University of Jordan together with its associated laboratory. The course serves three different departments with varying requirements and varying student initial background. The stages of the design process of the course and associated labs are explored. … …Journal of Computer Science, Vol. 6, Issue 2 · 28 Jun 2010 · 7,103 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,926 accessesView PDFCite
Research ArticleOpen accessIn the abstractModification Approach of Fuzzy Logic Model for Predicting of Cutting Force When Machining Nickel Based Hastelloy C-276Basim A. Khidhir, Bashir Mohamed, Mahmoud A.A. YounisProblem statement: Most Nickel based Hastelloy C-276 is a difficult-to-machine material because of its low thermal diffusive property and high strength at high temperature. Machinability consideration of nickel based Hastelloy C-276 in turning operations has been carried out using ceramic inserts under dry conditions. Approach: This study described a modification approach applied to a fuzzy logic based model for predicting … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,464 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Optimization of a 1.55 µm Waveguide Based on Silicon Planar Photonic CrystalsR. Bchir, A. Bardaoui, M. Machhout et al.Background: Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Objective: First, we varied the thickness of the Silicon slab and the pore radius in order to obtain optimum design parameters … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,476 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 abstractModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,169 accessesView PDFCite
Research ArticleOpen accessIn the abstractAgent-Based Design for E-learning EnvironmentKhadidja Harbouche, Mahieddine DjoudiWe presented an agent-based e-learning environment. Our aim was to allow many users to interact collectively and intelligently with the environment. In this cooperation model, human users and artificial agents carry out tasks in the learners’ service. We define the internal structure of our kernel supposed to work within Internet/Intranet settings. Design was structured in three parts: individual learning space, … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Consumption and Performance’s Library on DSPs: Case Study MPEG2Jalel Ktari, Mohamed Abid, Nathalie Julien, Johann LaurentThe growing demand for portable electronic devices has led to an increased emphasis on power consumption within the semiconductor industry. As a result, designers are now encouraged to consider the impact of their decisions not only on speed and area, but also on power throughout the design space exploration. This article presents a high-level design space exploration methodology. It allows … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 6,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impacts of Total System Design Factors on Human Performance in Power PlantsA. Azadeh, J. Nouri, I. Mohammad FamThe objective of this study is to evaluate the impact of total system design factors (TSD) on human performance in a power plant. The TSD factors are defined as design factors, which have an impact on the overall performance of the power plants in the context of total human engineering or macroergonomy. The systems being studied are the control rooms … …American Journal of Applied Sciences, Vol. 2, Issue 9 · 30 Sep 2005 · 6,677 accessesView PDFCite
