Research ArticleOpen accessIn the abstractDetermination of Metoprolol and Felodipine in Binary Mixture Using Chemometric-Assisted Spectrophotometric and High-Performance Liquid Chromatographic-UV MethodsHesham Salem, Ola M. AbdallahFour methods were developed for simultaneous determination of metoprolol and felodipine without previous separation. In the first method both drugs were determined using first derivative UV spectrophotometry, with zero crossing measurement at 222 and 235 nm for metoprolol and felodipine, respectively. The second method depends on first derivative of the ratios spectra by measurements of the amplitudes at 250.1 nm … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 8,028 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Nonlinearity Under Cyclic Loading In Neutron FlowAtwa D. Zeyad, E.I. StarovoitovThe influence of neutron irradiation on the nonlinear elastoplastic deformation of the constructions components under cyclic force disturbance was investigated. The formula of irradiation reinforcement was suggested depending on the experimental data, and the theorem of variable loading was proved. The problem of metal-polymeric sandwich beam was solved numerically. …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractDependencies Management in Dynamically Updateable Component-Based SystemsSaleh Alhazbi, Aman JantanThis paper discusses dependencies analysis significance when updating component-based system dynamically. It presents a service-based matrix model and nested graph as approaches to capture components' dependencies; it discusses using dependencies analysis for safe dynamic updating in component-based software systems; we advocate using service-based dependencies rather than component-based which refelect accurate effect during dynamic reconfiguration. …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractWavelet and ANN Based Relaying for Power Transformer ProtectionS. Sudha, A. Ebenezer JeyakumarThis paper presents an efficient wavelet and neural network (WNN) based algorithm for distinguishing magnetizing inrush currents from internal fault currents in three phase power transformers. The wavelet transform is applied first to decompose the current signals of the power transformer into a series of detailed wavelet components. The values of the detailed coefficients obtained can accurately discriminate between an … …Journal of Computer Science, Vol. 3, Issue 6 · 30 Jun 2007 · 6,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractProtein Molecular Structures, Protein SubFractions, and Protein Availability Affected by Heat Processing: A ReviewPeiqiang YuThe utilization and availability of protein depended on the types of protein and their specific susceptibility to enzymatic hydrolysis (inhibitory activities) in the gastrointestine and was highly associated with protein molecular structures. Studying internal protein structure and protein subfraction profiles leaded to an understanding of the components that make up a whole protein. An understanding of the molecular structure of … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 8,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Pulsewidth Analysis in the Presence of PMD and PDL in Optical Fibers Using Neural Network AlgorithmA. Sivasubramanian, V. C. RavichandranIn long haul networks, the random birefringence induced in the optical fiber leads to a considerable Polarization Mode Dispersion (PMD). Polarization Dependent Loss (PDL) mainly occurs in optical components and depends on the state of polarization of optical signals. The presence of PMD and PDL causes pulsewidth narrowing and the pulsewidth reduction depends on states of polarization at which the … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,055 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Quality and IndicatorsJorge Matute, A.P. GuptaThis study highlights the importance of collecting good quality data from multidisciplinary studies. Bias in data may be the result of instrument inaccuracies, imprecise data recording techniques, inaccurate data entry to computers or inappropriate statistical analysis and presentation. Recommendations for good data quality control are given. Different types of data are discussed: raw data, simple indicators and complex indicators. It … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Simulation of an Absorption Diffusion Solar Refrigeration UnitB. Chaouachi, S. GabsiThe purpose of this study was the design and the simulation of an absorption diffusion refrigerator using solar as source of energy, for domestic use. The design holds account about the climatic conditions and the unit cost due to technical constraints imposed by the technology of the various components of the installation such as the solar generator, the condenser, the … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow Youth in India and Lebanon Rate their IntelligenceRamzi Nasser, Sushila SinghalA sample of 648 Lebanese and 252 Indian students estimated their intelligences based on Gardner's 10 multiple intelligence. Males rated higher their body kinesthetic and religious dimension (spiritual) while females rated higher their verbal and intra-personal estimates of intelligence. Using the educational level of the parent, no significant correlation with self-estimates of intelligence for each of the national samples was … …Journal of Social Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 7,097 accessesView PDFCite
Research ArticleOpen accessIn the abstractProbabilistic Artificial Neural Network For Recognizing the Arabic Hand Written CharactersKhalaf khatatneh, Ibrahiem M.M. El Emary, Basem Al-RifaiThe objective of this study was to present a new technique assists in developing a recognition system for handling the Arabic Hand Written text. The proposed system is called Arabic Hand Written Optical Character Recognition (AHOCR). AHOCR was concerned with recognition of hand written Alphanumeric Arabic characters. In the present work, extracted characters are represented by using geometric moment invariant … …Journal of Computer Science, Vol. 2, Issue 12 · 31 Dec 2006 · 6,915 accessesView PDFCite
