Research ArticleOpen accessIn the abstractLow Cost Long Distance Detector for Explosives and Chemical Analysis by IEC ApplicationGeorge H. Miley, Heinrich Hora, Frederick Osman et al.A radiation source for detecting specific chemicals at several meter distances even behind walls, car doors or other barriers is the application of Million electron Volts (MeV) neutrons from nuclear fusion reactions at such low intensities to avoid any danger for human bodies. The chemical analysis consists in the neutron activation of nuclei emitting then gamma radiation of lines very … …American Journal of Applied Sciences, Vol. 2, Issue 11 · 30 Nov 2005 · 6,513 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Operational Features of Pumping Stations Equiped with Parallel-Connected Centrifugal Pumps for Land-ReclamationKhalid S. Al-RababaThe required water supply of a pump could be provided by means of different combinations of pressure piping and pumping units at different operational costs. The basic indices describing the operational modes for the individual and group pumping units, including the values of the efficiency, are computed. The adequacy of the calculational results that based on the developed mathematical models … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,802 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Fully Integrated Dual-Band Low Noise Amplifier for IEEE 802.11 and Hiper LAN ApplicationMow Shouxian, Ma Jianguo, Yeo Kiat Seng, Do Manh AnhA fully-integrated dual-band Low Noise Amplifier (LNA), which can be used for IEEE 802.11 and Hiper LAN applications, was investigated in this paper. The proposed LAN was implemented entirely pm a single chip based on a standard 0.18 μm 1P6M CMOS process. It draws 13 mA current from a 1.5-V voltage supply and achieves power gains of 17 and 10 … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,288 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordWomen in Informal Trade Amidst COVID-19: SOA Market CameroonTlholohelo Mojakisane, Brivery Siamabele, Matildah Kaliba, Rudo Phiri MumbaSARS-CoV-2, which stands for severe acute respiratory syndrome coronavirus 2, became a global health emergency in 2019. Even though the pandemic reached the African continent relatively late in 2020, it had already been terrorizing other parts of the world. In wake of the COVID-19, trade restrictions were imposed and affected the traders across the continent, but the impacts were enormous … …Journal of Social Sciences, Vol. 19, Issue 1 · 19 Jan 2024 · 6,023 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordDesign and Analysis of SRAM Cell for Smart ApplicationPushkar Praveen, Rakesh Kumar SinghIn today's circuittechnology, power consumption and savings are key concerns. The driving reasonsbehind these innovations are portable devices that require high throughput andlow power dissipation, such as computers, phones, and Personal DigitalAssistants (PDAs). In portable devices, reducing or decreasing IC dissipatedpower through design optimization is a big problem, and restricted batterylifespan places very severe restrictions on overall power usage. In … …Journal of Computer Science, Vol. 18, Issue 9 · 17 Sep 2022 · 5,726 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordLow Power Analog Multiplier Using MifgmosK. Duraisamy, U. RagavendranA novel 4-quadrant analog multiplier using Floating Gate MOS (FGMOS) transistors operating in saturation region are implemented. Floating gate MOSFETs are being utilized in a number of new and existing analog applications. These devices are not only useful for designing memory elements but also we can implement circuit elements. The main advantage in FGMOS is that the drain current is … …Journal of Computer Science, Vol. 9, Issue 4 · 14 May 2013 · 6,343 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordA Fast Series Active Filter using Sliding Mode Control to Correct and Regulate Unbalance Voltage in Three-Phase SystemTheerayuth ChatchanayuenyongProblem statement: A Sliding Mode Controller (SMC) with fast reference voltage generation to correct and regulate unbalance voltage in three-phase system was proposed. Approach: The compensation algorithm was not based on three-symmetrical component decomposition so the controller can yield a fast response that was essential in such a critical real time control work. The reference voltages were fed to the … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 7,221 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effects of Harmonic Components on Transformer Losses of Sinusoidal Source Supplying Non-Linear LoadsI. Daut, H. S. Syafruddin, Rosnazri Ali et al.An important consideration when evaluating the impact of harmonics is their effect on power system component and loads. Transformers are major components in power systems. The increased losses due to harmonic distortion can cause excessive losses and hence abnormal temperature rise. The measurement of iron losses and copper losses of single-phase transformers is important in particular for transformers feeding nonlinear … …American Journal of Applied Sciences, Vol. 3, Issue 12 · 31 Dec 2006 · 8,398 accessesView PDF Cite
