Research ArticleOpen accessIn the abstractThree Dimensional Flow Analyses in a Diagonal Type MHD GeneratorTriwahju Hardianto, Nobuomi Sakamoto, Nob. HaradaThis paper studied development of the three dimensional flow fields in a diagonal channel MHD generator. A diagonal insulating sidewalls type channel is proposed in this work. The partial-differential equations for the three momentum, the enthalpy and the electrical fields are solved by a finite-difference calculation procedure. The turbulence phenomenon is represented by two-equation turbulence model. Calculations have been made … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,917 accessesView PDFCite
Research ArticleOpen accessIn the abstractMathematical Modeling and Interpretation of PbPc Gas Sensor ArrayNidal F. Shilbayeh, Mahmoud Z. IskandaraniThe voltage/current characteristics and the effect of NO2 gas on the electrical conductivity of a PbPc gas sensor array is investigated. The gas sensor is manufactured using vacuum deposition of gold electrodes on sapphire substrate with the lead-phathalocyanine vacuum sublimed on the top of the gold electrodes. Two versions of the PbPc gas sensor array are investigated. The tested types … …American Journal of Applied Sciences, Vol. 3, Issue 6 · 30 Jun 2006 · 6,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractMPLS over Segmented WDM Optical Packet Switching NetworksHakim Mellah, Fouad M. AbbouWavelength Division Multiplexing (WDM) is a promising solution for data transport in future all-optical wide area networks. Such networks consist of fibers joined by dynamically controllable cross-connects which provide purely optical transport between pairs of network access stations. Optical packet switching (OPS) is optical switching with the finest granularity. Incoming packets are switched all-optically without being converted to electrical signal. … …Journal of Computer Science, Vol. 2, Issue 5 · 31 May 2006 · 6,750 accessesView PDFCite
Research ArticleOpen accessIn the abstractHarmonics Study and Comparison of Z-source Inverter with Traditional InvertersB. Justus Rabi, R. ArumugamThis paper presents an Impedance Source Inverter for A.C electrical drives. The impedance source inverter employs a unique impedance network cable with inverter main circuit and rectifier. By controlling the shoot-through duty cycle, the z-source inverter system using MOSFETS provide ride-through capability during voltage sags, reduces line harmonics, improves power factor and high reliability, and extends output voltage range. Analysis, … …American Journal of Applied Sciences, Vol. 2, Issue 10 · 31 Oct 2005 · 7,281 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
Review ArticleOpen accessIn the abstractSome Aspects of Modern DronesRelly Victoria Virgil PetrescuToday drones have become so important that everyday life can no longer be conceived without them. The paper wishes to present some essential aspects regarding modern drones, their capabilities and their uses. Drones and minnies drones have penetrated deep into technology, industry, agriculture, the military and police area, security services, security and control, aerial surveillance, signaling, aerial filming, cartography, danger … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 16 Jun 2021 · 8,444 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Model of Calcium Carbonate System of Soil SolutionAbdulmalik A. Batukaev, Anatoliy P. Endovitsky, Andrey G. Andreev et al.Carbonate system determines the basic processes of soil formation and evolution. The aim of research was to show the importance of chemical Carbonate Calcium Equilibrium (CCE) in soil solutions. CCE causes a degree of soil solution’s saturation with CaCO3 as a factor of carbonate geochemical cycle. CCE depends on chemical composition, pH, Eh, buffering properties of liquid phase, dissolution, migration, … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 18 May 2016 · 7,978 accessesView PDFCite
HypothesisOpen accessIn the abstractNew Opportunities for Fullerenes and for GrapheneClive DelmonteThis is a conjecture which defines a new class of electrically conducting polymer that chemically confines metals, ions or clusters within an electric potential constraining them to react in ways novel to chemistry. The polymers are planar on a planar surface and adhere as a П-bonded electron sheet to planar, electron-delocalized surfaces as in Fullerenes, graphene (both sides) and graphite. … …Current Research in Nanotechnology, Vol. 6, Issue 2 · 1 Jan 2016 · 13,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractAcquisition and Research of the p-3C-SiC Epitaxial Layers Based on the 6H-SiC Semi-Insulating SubstratesLebedev Alexander Alexandrovich, S.P. Lebedev, E.V. Bogdanova et al.By now we know almost nothing about works on production of p-3C-SiC. Probably, it is due to the fact that the basic acceptor impurity (aluminium) accumulates on the interfaces of the twins and other structural defects in the 3C film and it is electrically neutral. We managed to produce the highly doped layers p-3C based on the conducting substrates of … …American Journal of Applied Sciences, Vol. 12, Issue 3 · 27 May 2015 · 6,466 accessesView PDFCite
Research ArticleOpen accessIn the abstractON THE ABSENCE OF ANTIMATTER FROM THE UNIVERSE, DARK MATTER, THE FINE STRUCTURE PARAMETER, THE FLUCTUATIONS OF THE COSMIC MICROWAVE BACKGROUND RADIATION AND THE TEMPERATURE DIFFERENCE BETWEEN THE NORTHERN AND SOUTHERN HEMISPHERE OF THE UNIVERSEEmmanuil ManousosThe theory of selfvariations correlates five cosmological observations considered to be unrelated by the physical theories of the previous century. The absence of antimatter from the Universe, the Dark Matter, the slight variation of the fine structure parameter, the temperature fluctuations of the cosmic microwave background radiation and the temperature difference between the northern and southern hemisphere of the Universe … …Physics International, Vol. 5, Issue 1 · 28 Nov 2014 · 8,881 accessesView PDFCite
