Review ArticleOpen accessIn the abstractNikola TESLARelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Nicolae Tesla, has remained and spent most of his life, making it hard to pronounce "Teslea"), is considered to be the inventor of the alternating current and uncovered cableless power transmission. It is attributed to the transmission of energy through monophase, biphasic, polyphase alternating currents and transmission of non-wired energy by electromagnetic waves (oscillations) in the industrial alternating current frequency … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 6 Nov 2017 · 13,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractAirlanderRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Man always dreamed of flying. The important thing is not that it succeeded but that it has evolved permanently, improving its flight. The main problem in aviation was also the safety of the flight. How to keeps in the air, even when serious problems arise. Generally, the porting was made with engines and wings. But such support can’t be very … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 2 · 5 Jul 2017 · 7,925 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Rotation Effect on Shear Horizontal Surface Wave in a Piezoelectric Semi-Space Covered by a Semiconductor FilmFatimah AlshaikhIn this study, a mathematical model of the rotation effect on Shear Horizontally wave (SH-wave) propagation in a piezoelectric semi-space covered by a semiconductor film is investigated. The semiconducting layer is rotating with a constant angular velocity and the interface between the piezoelectric substrate and the semiconductor layer is imperfectly bonded. Furthermore, the surfaces of the bilayer system assumed free … …Journal of Mathematics and Statistics, Vol. 13, Issue 2 · 29 Apr 2017 · 7,211 accessesView PDFCite
InvestigationOpen accessIn the abstractDesign and Realization of Pre-Amplifier and Filters for on-Board Radar SystemN. Dinesh Kumar, R. Divya Ravali, Panchavati R. SrirekhaToday's warfare situation incorporates a considerable measure of innovative weaponry and every nation is attempting to outmaneuver the other utilizing high engineering, henceforth it is of most extreme criticalness to be at the front line of the bleeding edge innovation and having the best weapons conceivable to secure the country. One of the innovations which give the one having it … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 9 Nov 2015 · 7,803 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimations of Neutrino and Graviton Masses by a Phenomenological Mass Relation for Stable ParticlesDimitar T. ValevThe ratio between the proton and electron masses was shown to be close to the ratio between the shortest lifetimes of particles, decaying by the electromagnetic and strong interactions. The inherent property of each fundamental interaction is defined, namely the Minimal Lifetime of the Interaction (MLTI). The rest mass of the Lightest Free Massive Stable Particle (LFMSP), acted upon by … …Physics International, Vol. 6, Issue 2 · 25 Aug 2015 · 8,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractQuality Measurements on the Radio Interface of the Mobile Communication in the Proximity of the Power SystemSaid Ghnimi, Adnen Rajhi, Ali Gharsallah, Fakhreddine KhlifaProblem statement: The electric power lines and its associated equipments generally produce an electromagnetic noise in their environment, which are likely to have dangerous effects on propagation environment to the Global System for Mobile communication (GSM) cellular mobile network. Approach: In this study, we analyzed the characteristics of the power line noise and its correlation with the GSM burst; showing … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 26 Mar 2015 · 7,000 accessesView PDFCite
Research ArticleOpen accessIn the abstractHIGH IMPEDANCE SURFACES FOR FLEXIBLE AND CONFORMAL WIRELESS SYSTEMSHaider R. Khaleel, Hussain M. Al-Rizzo, Ayman Issac, Said AbushamlehRecent years have witnessed a great deal of interest from both scientific and academic communities in the field of flexible electronic systems. Most flexible electronic systems require the integration of flexible antennas operating in specific frequency bands to provide wireless connectivity which is highly demanded by today’s network oriented society. On the other hand, High Impedance Surfaces have become very … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 2 · 26 Jun 2014 · 7,218 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Lense-Thirring Effect in the Anomalistic Period of Celestial BodiesIoannis Haranas, Omiros Ragos, Ioannis GkigkitzisIn the weak field and slow motion approximation, the general relativistic field equations are linearized, resembling those of the electromagnetic theory. In a way analogous to that of a moving charge generating a magnetic field, a mass-energy current can produce a gravitomagnetic field. In this contribution, the motion of a secondary celestial body is studied under the influence of the … …Space Science International, Vol. 1, Issue 2 · 9 Dec 2013 · 8,457 accessesView PDFCite
