Research ArticleOpen accessIn the abstractEffect of Adding Dexmedetomidine versus Fentanyl to Intrathecal Bupivacaine on Spinal Block Characteristics in Gynecological Procedures: A Double Blind Controlled StudySubhi M. Al-Ghanem, Islam M. Massad, Mahmoud M. Al-Mustafa et al.Problem statement: The purpose of this study was to evaluate the onset and duration of sensory and motor block as well as operative analgesia and adverse effects of Dex Metedo Midine (DXM) or fentanyl given intrathecally with plain 0.5% bupivacaine for spinal anesthesia. Approach: seventy six patients classified as American Society of Anesthesiologists (ASA) status I, II and III scheduled … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 14,172 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of adjusting PH on Stretchability and Meltability to White Brined Nabulsi CheeseAyman Suliman Mazahreh, Jihad M. Quasem, Ali Faleh Al-Shawabkeh, Ibrahim Abdullah AfanehProblem statement: Boiled white brined (Nabulsi cheese) is the mostly consumed in Jordan; this cheese should show meltability and high stretchability in order to fit in the production of high quality Kunafa and other popular local sweets and pastries.The most outstanding characteristic of Nabulsi cheese is the long keeping ability (more than one year) without cooling, since it is preserved … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 3 Apr 2009 · 7,786 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntelligent OkiKoSenPBX1 Security Patrol Robot via Network and Map-Based Route PlanningMbaïtiga ZacharieProblem statement: With an increased demand for security and limited numbers of trained security personnel, some security mangers have a lot of ground to police and limited staff to cover it. To compensate for shortages of security staff and to reduce the stress of security managers, we have developed an intelligent patrol robot system called "OkiKoSenPBX1". The system integrates a … …Journal of Computer Science, Vol. 5, Issue 1 · 31 Jan 2009 · 7,410 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpeed Estimation of Adaptive Fuzzy-Controlled Piezo-Electric Motor using MLP-Neural NetworkShebel ALSABBAH, Tariq MUGHRABIThe speed of ultrasonic motor of piezo-electric type is usually measured using mechanical sensors such as pulse encoders. However, these sensors are costly and bulky. In this paper, a numerical speed estimation approach of a piezo-electric motor (PEM) is implemented using multilayer perception neural network (MLP-NN). The proposed model evaluates rotational speed and load torque based on the amplitude and … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 6,785 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Twelve Dielectric Moisture Probes for Soil Water Measurement under Saline ConditionsM. Inoue, B.A. Ould Ahmed, T. Saito, M. IrshadRecently the research on the determination of soil water content and electrical conductivity using automated technique has received tremendous attention. Selecting the type of system that should be used for soil water measurement under saline conditions depends on its precision. A laboratory study was carried out to measure the soil water content (θ) and soil solution electrical conductivity (ECw) using … …American Journal of Environmental Sciences, Vol. 4, Issue 4 · 31 Aug 2008 · 7,450 accessesView PDFCite
Research ArticleOpen accessIn the abstractTime-Marching Method for Computations of High-Speed Compressible Flow on Structured and Unstructured GridK.C. Ng, M.Z. Yusoff, K. Munisamy et al.The development of Computational Fluid Dynamics (CFD) compressible codes for 2D structured quadrilateral grid and 3D unstructured hexahedral grid is described. The high-speed flow in a nozzle blade cascade is predicted numerically by solving the 2D/3D Euler Equations in a coupled manner. The new finite volume CFD solvers employ second-order accurate central differencing scheme for spatial discretization and multi-stage Runge-Kutta … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 2 · 30 Jun 2008 · 7,348 accessesView PDFCite
Research ArticleOpen accessIn the abstractMiniature-Autopilot Evaluation SystemKamal Ali, Lamarious CarterThis research describes a Hardware in the Loop Simulator (HILS) that was developed to enhance the quality of attitude data received from autopilots. The described system aided in adjusting the contribution of individual IMU sensors and thereby improved the accuracy of IMU data. The HILS system outlined in this research is a gimbaled platform equipped with four stepper motors and … …Journal of Computer Science, Vol. 4, Issue 1 · 31 Jan 2008 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modeling Approach for Collision Avoidance in Robotic SurgeryReza Ramezanifard, Javad Dargahi, Siamak Najarian, Farhad Tabatabai GhomsheWe present a new system that can be used in combination with an array of ultrasonic piezoelectric sensors and has application in surgical navigation procedures. Using the proposed assembly, the maneuverability of the surgical tools can be enhanced and the incidence of potentially damaging contact with non-target tissue can be reduced. The emphasis of our work was based on controlling … …American Journal of Applied Sciences, Vol. 4, Issue 9 · 30 Sep 2007 · 6,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Near Real-time Early Warning System on Erosion HazardsFaisal H. Ali, Tew K. HuiWith many incidences of landslides, mudslides and erosion occurrences lately, especially in the highlands in Malaysia, properties were damaged and lives were lost. Seeing the need of resolving and minimizing such untoward incidences, a study has been embarked on developing a near real-time early warning system on erosion hazards so as to provide an early warning to the public, whenever … …American Journal of Environmental Sciences, Vol. 2, Issue 4 · 31 Dec 2006 · 6,706 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew RFID System Architectures Supporting Situation Awareness under Ubiquitous EnvironmentsDongwon Jeong, Young-Gab Kim, Hoh InMany sensors providing situation data will be in everywhere under the ubiquitous environment. The current RFID system should be extended to recognize and use situation information from the sensors. This study proposes RFID system architectures that are suitable for the ubiquitous environment. This study applies the situation awareness concept to and extends the current RFID system architecture to be able … …Journal of Computer Science, Vol. 1, Issue 2 · 28 Jul 2006 · 7,045 accessesView PDFCite
