Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of the Performance of Single-Phase Capacitor-Run Induction MotorMahdi Salman AlshamasinThe aim of the study was to suggest optimal solution for the impact of harmonics on the performance of Capacitor-Run Motor (CRM), the most commonly used single-phase motor. Therefore, investigations were carried out over the entire slip from no-load condition up to the locked-rotor condition, for harmonics of various orders in the case of using Pulse-Width Modulation (PWM) speed control. … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractSerum Levels of Insulin-Like Growth Factor-I, Thyroid Hormones and Skeletal Muscle Fiber Size in Castrated Lambs with and Without Androgen TreatmentBani Z. Ismail, O. M. AL-Ababneh, M. B. AL-ZghoulTwelve, intact male lambs, 1-2- weeks old, were divided into 3 groups, Group W (4 lambs) were castrated at age less than 1 month, group WT (4 lambs) were castrated at the same age and treated with testosterone and group R (4 lambs) were left intact and served as control. Testosterone Propionate replacement was administered intramuscularly at a dose of … …American Journal of Applied Sciences, Vol. 6, Issue 3 · 31 Mar 2009 · 7,122 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of a Smart Multi Purpose Electronic Nose SystemMahmoud Z. Iskandarani, Nidal F. ShilbayehAn electronic nose system for multi application purposes is designed and tested. Our hardware design allows various types of sensors to be used for different applications. The system is capable of being interfaced to both analog and digital instruments with special filtering devices that isolate the system from surrounding signals. The design of the system is distinguished through the use … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Implementation of Myoelectric Controlled ArmTariq M. Younes, Mohammad A. AlKhedher, Abdel-Hamid Soliman, Aiman Al AlawinIn this study a discrimination system, using a neural network for Electromyogram (EMG) externally controlled Arm is proposed. In this system, the Artificial Neural Network (ANN) is used to learn the relation between the power spectrum of EMG signal analysed by Fast Fourier Transform (FFT) and the performance desired by handicapped people. The Neural Network can discriminate 4 performances of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 16 Sep 2019 · 6,281 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Cost Smart Sensor DesignTakialddin A. Al SmadiProblem statement: Sensor with local processing power that enables it to react to local conditions without having to refer back to the central controller. The size and the cost of smart sensor circuit have been reduced. Approach: The use of microcontroller, such as (PIC16C715), with an 8-bit ADC (Analogue to Digital Converter) in one chip. This reduction in the circuit … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 1 · 11 Feb 2016 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Programmable Gate Array-Based Pulse-Width Modulation for Single Phase Active Power FilterN. A. Rahim, Z. IslamProblem statement: The design and implementation of a sinusoidal Pulse-Width Modulation (PWM) generator for a single-phase hybrid power filter is presented. Approach: The PWM was developed in an Altera® Flex 10 K Field Programmable Gate Array (FPGA) and the modulation index was selected by calculating the DC bus voltage of the active filter through a digital controller, by Proportional-Integral-Derivative (PID) … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,293 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Internal Flow Patterns on Heat transfer Performance of a Closed-end Oscillating Heat Pipe at Vertical PositionS. Rittidech, L. Yodluk, K. SongsornThis article describes the effects of varying bond numbers (Bo) and aspect ratios (Le/d) on flow pattern of a close-end oscillating heat-pipe (CEOHP). The CEOHPs used employed a glass tube with inside diameter of 3 mm. The length of evaporator of 100 and 150 mm (the lengths of evaporator adiabatic and condenser section were equal) were employed with 10 turns. … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,062 accessesView PDFCite
Research ArticleOpen accessIn the abstractANN Based DSPIC Controller for Reactive Power CompensationR.A. Jayabarathi, N.B. DevarajanIn India with a power shortage of about 10% of installed capacity, the transmission and distribution losses are relatively high. One of the reasons for the large loss is the excessive reactive loads on the primary distribution feeder. With the right amount of reactive power compensation, as system load varies, line losses can be considerably reduced. The application of Artificial … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 6,851 accessesView PDFCite
