Research ArticleOpen accessIn the abstractThe Application of Electrochemical Impedance Techniques in Analyzing the AC Response of Some Two-electron Transfer Dye SystemsFarouk RashwanThe Electrochemical Impedance Spectroscopic techniques (EIS) were used to investigate the behavior of some dye compounds (quinoid systems) characterized with 2e-transfer processes. For this purpose, Alizarin Red S (ARS), Alizarin Cyanine (AC), Alizarin Viridin (AV) and carminic acid were chosen for the measurements. The EIS experiments were performed using a small AC amplitude (10 mV p-p) in addition to a … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 6,780 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Note towards Reshaping Java's FeaturesN. S. Kutti, Z. A. Al-Khanjari, H. A. Ramadhan, J. FiaidhiProgramming Languages continually go through the refinement process due to several findings such as lack of robustness, lack of flexibility, lack of simplicity and lack of standard. This may require pruning undesirable features, sometimes softening of hard nature of some features and adding new features to improve the scope of the languages. Recently Java has emerged as a refined language … …Journal of Computer Science, Vol. 1, Issue 4 · 30 Dec 2005 · 6,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractEOS: Evolutionary Overlay Service in Peer-to-Peer SystemsL. I. Zhijun, Liao MinghongThe peer-to-peer (P2P) systems nowadays can be mainly classified into two categories: structured and structure-less systems based on their overlay organization. The structured systems can achieve determinate efficiency due to their rigorous structure with the cost of losing robustness and vice versa. We provide a semi-structured overlay based on the separation of routing structures and overlay organizations in this paper … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 6,349 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroduction to the Besov Spaces and Triebel-Lizorkin Spaces for Hermite and Laguerre expansions and some applicationsA. Iris, P. LopezWe introduced new definitions of Besov spaces and Triebel-Lizorkin spaces associated with multidimensional Hermite expansions and multidimensional Laguerre expansions. We showed that the set of p-integrable functions is a Triebel-Lizorkin space with respect to the Gaussian measure and similarly, with respect to the probabilistic Gamma measure. Also, we showed that the Gaussian Sobolev spaces and Laguerre Sobolev spaces are Triebel-Lizorkin … …Journal of Mathematics and Statistics, Vol. 1, Issue 3 · 30 Sep 2005 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectrochemical Characteristics of Some Purpurins in Aqueous and Nonaqueous SolutionsFarouk A. Rashwan, Hossnia S. Mohran, Ahmed A. El-SamahyThe Electrochemical Impedance Technique (EIS) and the Cyclic Voltammetric method (CV) were used to investigate the behavior of purpurin (P), Anthrapurpurin (AP) and Benzopurpurin (BP) in aqueous and in N, N-dimethylformamide (DMF) media. In the CV experiments, both the radical and the dianion of these substances were assumed to form of limited stability due to chemical protonation. In case of … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,743 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of A.C. Impedance Spectroscopic and Cyclic Voltammetric Behavior of Some Heterocarbonyl Compounds in Both Aprotic and Aqueous MediaFarouk A. RashwanThe electrochemical behavior of eosin, isatin and alloxan in aqueous KNO3 and NaClO4 solutions on the Hanging Mercury Drop Electrode [HMDE] and in aprotic DMF and CH3CN on the Pt-disk electrode at 298 K was investigated using the Cyclic Voltammetry (CV) and the Electrochemical Impedance Techniques (EIS). In the CV experiment, the electroreduction of eosin in both aqueous and non-aqueous … …American Journal of Applied Sciences, Vol. 2, Issue 7 · 31 Jul 2005 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroducing Song Form Intelligence into Streaming AudioKevin CurranWhen receiving streaming media over a low bandwidth wireless connection, users can experience not only packet losses but also extended service interruptions. These dropouts can last for as long as 15 sec. During this time no packets are received and if not addressed, these dropped packets cause unacceptable interruptions in the audio stream. A long dropout of this kind may … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,572 accessesView PDFCite
Research ArticleOpen accessIn the abstractRevisiting Share Market Efficiency: Evidence from the New Zealand Australia, US and Japan Stock IndicesChristopher Gan, Minsoo Lee, Au Yong Hue Hwa, Jun ZhangThis study aims to re-examine the market efficiencies in New Zealand Stock Exchange (NZSE) and Australia Stock Exchange (ASX) stock indices to investigate whether Groenewold’s[1] findings still hold in the period after the financial liberalization (January 1990-January 2003). In addition, the study also examines whether the larger US NYSE and Japanese NIKKEI stock indices have any influence on the NZSE … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a LOW Cost IC TesterLiakot Ali, Roslina Sidek, Ishak Aris et al.Low cost Integrated Circuit (IC) testing is now a burning issue in semiconductor technology. Conventional IC tester, Automatic Test Equipment (ATE), cannot cope with the today’s continuously increasing complexities in IC technology. Deterministic algorithm, which is an idea of 1960’s, is adopted in the ATE. Recently pseudo-random testing approach of IC testing has been emerged as an economically viable alternative … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 7,063 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Current Sensor for IDDQ Testing of CMOS ICMohd Liakot Ali, Nurul Huda KhamisThis study presents the design of an off-chip current sensor for IDDQ testing of CMOS (Complementary Metal-oxide Semiconductor) ICs (integrated circuit). It provides a linear voltage signal of IDDQ current with a conversion factor of 5 mV/μA without any amplification. A voltage-controlled switch is used to bypass the transient current peaks. It has also been shown that the sensor is … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,834 accessesView PDFCite
