Research ArticleOpen accessIn the abstractImproving Reliability and Productivity of an Aluminum Extruder by Implementation of Direct Torque Control TechnologyMazouz A. SalahatProblem statement: The linear motor drive is widely used in driving an extrusion puller in an aluminum extrusion industry. The main disadvantage of this drive is manual and step-wise torque control. This research was done to replace the linear motor drive by AC drive with direct torque control technology. Approach: Mathematical calculations were carried to select an AC drive which … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,267 accessesView PDFCite
Research ArticleOpen accessIn the abstractImprovement on the Design of a Cabinet Grain DryerAdzimah K. Stephen, Seckley EmmanuelProblem statement: Grains are routinely seen dumped in villages and major cities during the peak of harvest. Therefore it is necessary that these grains are properly dried and stored to ensure availability and wholesomeness throughout the year. Advancements have taken place in the practice of drying since the first world war. Manufacturing methods have greatly improved production rate and the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,720 accessesView PDFCite
Research ArticleOpen accessIn the abstractDisplacement of Boron from the Silicon Crystal Nodes by Interstitial Si Atoms During Implantation and AnnealingM. Jadan, A. R. Chelyadinskii, V. Y. YavidThe process of boron displacement from the nodes into interstitial positions of interstitial Si atoms in silicon (Watkins effect) on the conditions of implantation and annealing has been investigated with the help of X-ray diffraction and electrical methods. It was revealed that the efficiency of the Watkins substitution is determined by the ion current density (level of ionization). With increasing … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,983 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign of a Synchronous Reference Frame Controlled Fuzzy Logic Based Distribution Static Compensator to Enhance Distribution System Power QualityRekha Sampath, Lokesh Mallaiah, Ashwini A V et al.The demand for enhanced power quality in distribution systems has increased due to the widespread utilization of various AC loads, including rectifiers, inductive loads, and variable speed drives. When these nonlinear loads are combined with renewable energy sources, harmonics are introduced in the system. These can affect the way other equipment in the network works and leave the system vulnerable … …Journal of Computer Science, Vol. 22, Issue 2 · 27 Feb 2026 · 1,710 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHighly-Efficient Advanced Thermoelectric Devices from Different Multilayer Thin FilmsSatilmis Budak, Zhigang Xiao, Barry Johnson et al.The efficiency of the thermoelectric materials and devices is shown by the dimensionless Figure of merit, ZT. ZT is calculated by multiplying the Seebeck coefficient with square of the electrical conductivity and absolute temperature and dividing it all by the thermal conductivity. Thermoelectric devices were prepared using different multilayered thin film structures in the order of SiO2/SiO2 + Ge/Ge/Sb + … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 2 · 27 Apr 2016 · 8,368 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordTHE ELECTRICAL PROPERTIES OF Mg-Cu-Zn FERRITES IRRADIATED BY γ-RAYS OF 60Co SOURCEMohamed Eltabey, H. Ebrahim Hassan, Ismail Abd Elrahim AliFerrite samples with chemical formula MgxCu0.5-xZn0.5Fe2O4 (x = 0.0, 0.2 and 0.4) was prepared by the conventional ceramic method. The enhanced changes in the dc/ac resistivity and the dielectric constant due to γ-rays irradiation by 60Co source were measured using the two probes technique. The samples showed decreasing of their resistivity at room temperature after irradiation for both dc and … …American Journal of Applied Sciences, Vol. 11, Issue 1 · 10 Dec 2013 · 7,478 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordManagement of Effective Factors in Components’ Supply Chain on Losses of Electric Distribution SystemM. Esmaeil Honarmand, M. Sadegh Ghazizadeh, Ali KermanshahRestructuring in the electrical distribution utilities, the loss management is one of the critical activities to enhance network efficiency. Accordingly, management of technical loss would be the main target of the asset managers. For loss management, the usual methods of loss calculation and estimation need numerous data which is not used to real networks. In this research, a practical method … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 21 Apr 2018 · 7,551 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHistory Based Probabilistic Backoff AlgorithmNarendran Rajagopalan, C. MalaPerformance of Wireless LAN can be improved at each layer of the protocol stack with respect to energy efficiency. The Media Access Control layer is responsible for the key functions like access control and flow control. During contention, Backoff algorithm is used to gain access to the medium with minimum probability of collision. After studying different variations of back off … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 3 · 29 Aug 2012 · 7,662 accessesView PDFCite
