Research ArticleOpen accessIn the keywordsExperimental Antenna and Circuit Model for Charging an Electronic Device from the Ambient Electromagnetic WavesPankaj Chandra Kar, Md. Ariful Islam, Amit Paul et al.Electronic device use is on the rise as more and more tasks in everyday life are conducted online. As a consequence, charging is a unique aspect of any electronic device. However, the capacity of any electronic device's battery is fixed. On the other hand, charging the unit at any time and in any place is incredibly difficult. As a result, … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 18 Jan 2022 · 7,204 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMODELING THE UNIVERSE AS A QUANTUM WELLMichael Harney, Julie SealBy modeling the Universe as a quantum well for standing waves and solving Schrodinger’s equation for a particle trapped in this well, the solutions for the allowable rest-energies of all particles in the Universe are obtained, from the mass of the photon up to the mass of the Universe. The quantum numbers that predict the allowable rest-energies of all particles … …Physics International, Vol. 5, Issue 1 · 19 Mar 2014 · 8,241 accessesView PDF Cite

Research ArticleOpen accessIn the abstractACKA 500 WATT POWER AMPLIFIER FOR A 144 MHZ CHANNEL BASED ON A VHF PUSH-PULL POWER MOS TRANSISTORAgus Harjoko, Tri Wahyu SupardiIn a wireless communication, a signal power amplifier is needed to carry signals over a long distance. Many signal amplifiers are made of tube as the amplifying component and as such they suffer low efficiency. This study presents results of the research on designing and implementing solid state 144MHz signal amplifier employing MOSFET BLF278 as the active component of the … …Journal of Computer Science, Vol. 9, Issue 10 · 5 Sep 2013 · 7,615 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNanoscale Pitch Standards Sample Fabricated using Laser-Focused Atomic DepositionYan Ma, Tongbao Li, Yajun Zhao et al.Problem statement: Nanotechnology is already a large sector of industry and science research and it is expected to continue to grow at very fast rate. The determination of absolute measurements of length at the nanometer scale and below is very difficult and expensive. So the nanoscale metrology standard is needed. Approach: The laser-focused atomic deposition is a new way to … …Current Research in Nanotechnology, Vol. 2, Issue 2 · 3 Sep 2012 · 7,245 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Role of Sine and Cosine Components in Love Waves and Rayleigh Waves for Energy Hauling during EarthquakeZainal Abdul Aziz, Dennis Ling Chuan ChingProblem statement: Love waves or shear waves are referred to dispersive SH waves. The diffusive parameters are found to produce complex amplitude and diffusive waves for energy hauling. Approach: Analytical solutions are found for analysis and discussions. Results: When the standing waves are compared with the Love waves, similar cosine component is found in both waves. Energy hauling between waves … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 7,582 accessesView PDF Cite
