Research ArticleOpen accessIn the abstractHigher-Order Newton-Cotes FormulasPedro Americo Almeida Magalhaes Junior, Cristina Almeida MagalhaesProblem statement: The present work offers equations of Newton-Cotes Integration until twenty segments. Approach: It shows Newton-Cotes closed and open integration formulas. The new type Newton-Cotes semi-closed or semi-open was proposed. Results: An analysis of error in the technique was made. To estimate the error of integration in discrete data, we propose apply different rules or mix several rules. Conclusion/Recommendations: … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 9,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvective Heat Transport in an Unconfined Aquifer Induced by the Field Injection of an Open-Loop Groundwater Heat PumpStefano Lo Russo, Glenda TaddiaProblem statement: The increasing diffusion of low-enthalpy geothermal open-loop Groundwater Heat Pumps (GWHP) providing buildings air conditioning requires a careful assessment of the overall effects on groundwater system, especially in the urban areas. The impact on the groundwater temperature in the surrounding area of the re-injection well is directly linked to the aquifer properties. Physical processes affecting heat transport within … …American Journal of Environmental Sciences, Vol. 6, Issue 3 · 30 Jun 2010 · 7,970 accessesView PDFCite
Research ArticleOpen accessIn the abstracte-Learning Management System Using Service Oriented ArchitectureMohammed A. Jabr, Hussein K. Al-OmariProblem statement: Service Oriented Architecture (SOA) defines how to integrate widely disparate applications for a world that is Web based and uses multiple implementation platforms. Using (SOA) one can build durable e-learning contents, regardless of changes or evolutions in technology. This means that new content should be added to existing content without costly redesign, reconfiguration, or recoding. Approach: In this … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 9,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractSingle Beam Z-Scan Measurements of Nonlinear Refraction and Nonlinear Absorption Coefficients in Silver Nano-FluidEsmaeil Shahriari, W. Mahmood Mat YunusProblem statement: The nonlinear refractive index and nonlinear absorption are two important optical phenomena which are extensively used in optical switching, optical limiting and labeling. Approach: In the present research we had measured nonlinearity of Ag nano-fluid prepared using γ-irradiation method. The measurement was carried out using a single beam z-scan technique. Under a CW laser beam excitation operated at … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,635 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of Open Heart Surgery (Coronary Bypass) on Depression and Social Adjustment of Hospitalized Heart PatientsFarah Naderi, Alireza Heideri, Marjan Kargarzadeh, Mohammad TahmasbiProblem statement: Post treatment preparation is critical period, as patients may have difficulties with psychosocial adjustment, especially related to dissatisfaction with side effects of medicine taking therapy and a lack of socialization skills/social competence. Different psychological issues arise for patients depending upon where they are in the medical treatment process. Approach: The current research was processed with the intention of … …Journal of Social Sciences, Vol. 5, Issue 4 · 31 Dec 2009 · 7,985 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Policy-Based Admission Control Scheme for Voice over IP NetworksSami Alwakeel, Agung PrasetijoProblem statement: In Voice Over IP (VOIP) network, when more calls are admitted to the network, more voice packet traffic is created. Since bandwidth is always limited, this may result network congestion and/or may affect voice quality. Thus, we needed a mechanism for improving the Quality of Service (QoS) by controlling VOIP calls admission. Approach: Given a specified bandwidth and … …Journal of Computer Science, Vol. 5, Issue 11 · 30 Nov 2009 · 6,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Platform to Develop a Secure Instant Messaging Using Jabber ProtocolGhossoon M.W. Al-SaadoonProblem statement: Open Source technologies are interesting in that they allow free experimentation and integration by anyone and anywhere. A Jabber user can control presence with very little effort. Another user, regardless of external platform, must subscribe to your presence. You have the choice of rejecting or accepting the subscription at the time it is submitted. Approach: Other applications of … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,163 accessesView PDFCite
Research ArticleOpen accessIn the abstractPolicies Affect the Application of Information and Communication Technologies by Agricultural Extension ServiceSeyed Jamal F. Hosseini, Mehrdad Niknami, Gholamreza H. Hosseini NejadProblem statement: The majority of rural population in Iran has limited access to agricultural information. However, bridging the digital divide between urban and rural areas has been a major challenge for authorities in Iran. Agricultural extension by its nature can have an important role in this regard. Approach: This study aimed at examining the perception of extension specialists in Iran … …American Journal of Applied Sciences, Vol. 6, Issue 8 · 31 Aug 2009 · 7,323 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Computer Simulation Model for Automated Quantification of Luteinizing Hormone SecretionAyman Al-Nsour, Hamza A. Ali, Buthynna Al-Dulaimi, Wisam H. Al-SewadiProblem statement: An automated software package is developed for quantifying Luteinizing Hormone (LH) release from pituitary gonadotropes in response to short pulses of Gonadotropin-Releasing Hormone (GnRH). Approach: These computer programs were designed to accommodate the release mechanism that consists of three stages, namely; (1) Production of different concentrations of effectors (such as receptor-hormone binds, G protein interactions, inositol 1,4,5-trisphosphate IP3), … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 6,938 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncremental DataGrid Mining Algorithm for Mobility Prediction of Mobile UsersU. Sakthi, R.S. BhuvaneswaranProblem statement: Mobility prediction is the important issue in Personal Communication Systems (PCS). Mobile users moving logs are stored in data grid located in different locations. Distributed data mining algorithm is applied on this moving logs to generate the mobility pattern of mobile users. As new moving logs are added to the data grid, existing mobility pattern becomes invalid and … …Journal of Computer Science, Vol. 5, Issue 2 · 28 Feb 2009 · 6,775 accessesView PDFCite
