Research ArticleOpen accessIn the abstractSingle-Electron Transistor (SET) Process and Device Simulation Using SYSNOPSYS TCAD ToolsUda Hashim, Amiza RasmiSimulation of semiconductor device fabrication and operation is important to the design and manufacture of integrated circuits because it provides insights into complex phenomena that cannot obtained through experimentation or simple analytic models. Process and device simulation is commonly using for the design of new very large scale integration (VLSI) devices and processes. Simulation programs serves as exploratory tools in … …American Journal of Applied Sciences, Vol. 3, Issue 7 · 31 Jul 2006 · 7,418 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of X-Ray Diffractometry (XRD) for Identification of Fritillaria According to Geographical OriginWang Shujun, Yu Jinglin, Gao WenyuanFritillaria is a traditional Chinese herbal medicine for anti-tussive and expectorant use in China and some other Asian countries. The Fritillaria Chinese medicine material derived from different geographical origins is always difficult to discriminate each other. The objective of the study is to develop a nondestructive and simple method to identify five Fritillaria Chinese materia medica such as Fritillaria thunbergii … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,108 accessesView PDFCite
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 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 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
