Research ArticleOpen accessIn the abstractThe Marginalization of Globally-Born Businesses: Ethnically Divided Trade in Hamburg and the World Economy-The Case of Global Persian Carpet Trade through Ethnic NetworksShahamak RezaeiProblem statement: Persian carpets have long been a major commodity in the world market, controlled by the Tehran Carpet Bazaar and the Hamburg Free Harbor. Today about 200 private traders in the Hamburg Free Harbor area export their carpets to about 10,000 private carpet traders throughout the world, these being mainly of Iranian origin. The case of Persian Carpet represents … …American Journal of Economics and Business Administration, Vol. 1, Issue 2 · 30 Jun 2009 · 7,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractImplementing a Vector Controller Using 68k ProcessorsMohammad Bagher, Bannae Sharifian, Mohammad Reza Feyzi et al.Problem statement: This study described the design of a 3-phase AC Induction Motor (ACIM) vector control drive with position encoder coupled to the motor shaft. Approach: It was based on free scale's (Motorola's) 68k micro processor devices. Although the free scale 56F80x (56800 core) and 56F8300 (56800E core) families were well-suited for digital motor control and offer all things was … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,686 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradative Plasmid and Heavy Metal Resistance Plasmid Naturally Coexist in Phenol and Cyanide Assimilating BacteriaBahig El. Deeb, Abdullah D. AltalhiProblem statement: Heavy metals are known to be powerful inhibitors of xenobiotics biodegradation activities. Alleviation the inhibitory effect of these metals on the phenol biodegradation activities in presence of heavy metals resistant plasmid was investigated. Approach: Combination of genetic systems of degradation of xenobiotic compound and heavy metal resistance was one of the approaches to the creation of polyfunctional strains … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 11,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractDistributed Mutual Exclusion Based on Causal OrderingMohamed Naimi, Ousmane ThiareProblem statement: Causality among events, more formally the causal ordering relation, is a powerful tool for analyzing and drawing inferences about distributed systems. The knowledge of the causal ordering relation between processes helps designers and the system itself solve a variety of problems in distributed systems. In distributed algorithms design, such knowledge helped ensure fairness and liveness in distributed algorithms, … …Journal of Computer Science, Vol. 5, Issue 5 · 30 May 2009 · 6,748 accessesView PDFCite
Research ArticleOpen accessIn the abstractClosed form Solution for Scheduling Arbitrarily Divisible Load Model in Data Grid Applications: Multiple SourcesMonir Abdullah, Mohamed Othman, Hamidah Ibrahim, Shamala SubramaniamScheduling an application in data grid was significantly complex and very challenging because of its heterogeneous in nature of the grid system. When the Divisible Load Theory (DLT) model had emerged as a powerful model for modeling data-intensive grid problem, Task Data Present (TDP) model was proposed based on it. This study presented a new Adaptive TDP (ATDP) for scheduling … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 8,433 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe New Variable-Length Key Symmetric CryptosystemDavood Rezaei Pour, Mohamad Rushdan Md Said, Kamel Ariffin Mohd Atan, Mohamed OthmanProblem statement: In this study, we proposed a new 64-bit block cipher that accepted a variable-length key up to 512 bits, which was suitable for implementation in a variety of environments. Approach: The cipher algorithm was a 16-round Feistel network with a bijective function f and was made up of two key-dependent 16×16 S-boxes, bitwise rotations, and a carefully designed … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Land Uses' Consequences in Coastal Area of Faliraki and Delta Penaeus River in GreeceAgisilaos EconomouProblem statement: The areas of Faliraki and Delta Pinaeus river is presented with downgrade in natural resources that has a direct affect on the future development of these areas. This research investigated (i) whether land uses have downgraded the coastal areas (ii) to which degree the determination of land uses can play an important role in the reduction of environmental … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 7,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalytical Investigation of Hyperbolic Equations via He's MethodsD.D. Ganji, M. Amini, A. KolahdoozPerturbation methods depend on a small parameter which is difficult to be found for real-life nonlinear problems. To overcome this shortcoming, two new but powerful analytical methods were introduced to solve nonlinear heat transfer problems in this Letter, one is He's Variational Iteration Method (VIM) and the other is the Homotopy-Perturbation Method (HPM). Nonlinear hyperbolic equations were used as examples … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,115 accessesView PDFCite
Research ArticleOpen accessIn the abstractNonlinear Behavior of Single Piles in Jacket Type Offshore Platforms Using Incremental Dynamic AnalysisMohammad Amin Assareh, Behrouz AsgarianThe operation for offshore oil has become an important issue in the recent years. Offshore platforms are some of those structures which are built to withstand environmental and accidental loads during oil exploitation operation. One of the most usual types of these platforms is the Jacket Type Offshore Platform (JTOP) which can be divided into three important parts, which are … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 9,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Robust Video Watermarking AlgorithmTahani Al-Khatib, Ali Al-Haj, Lama Rajab, Hiba MohammedProblem statement: Video watermarking is well known as the process of embedding copyright information in video bit streams. It had been proposed in recent years to solve the problem of illegal manipulation and distribution of digital video. Approach: In this study, an effective, robust and imperceptible video watermarking algorithm was proposed. This algorithm was based on a cascade of two … …Journal of Computer Science, Vol. 4, Issue 11 · 30 Nov 2008 · 6,870 accessesView PDFCite
