Review ArticleOpen accessIn the keywordsOn Mars there was WaterFlorian Ion Tiberiu PetrescuScientists overseeing Curiosity's mission on Mars confirmed that the shape and size of the pebbles on the dry tracks indicate that they were transported and eroded by the waters. According to them, the rover found the roots of rocks equivalent to the flowing waters on Earth. The planet Mars, the closest to Terra, had life conditions similar to our blue … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 11 May 2018 · 8,628 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Exploitation of Errors in Redundant Residue Number System ArchitectureYaw AfriyieResidue Number System (RNS) is an unweighted number system that symbolizes big integers with smaller numbers. It can perform operations in particular addition and multiplication in parallel. Because of this property, RNS is extensively used in communication, Finite Impulse Response (FIR), cryptography and signal processing devices. The transfer of data in digital channels is very important for some critical applications … …American Journal of Applied Sciences, Vol. 18, Issue 1 · 30 Jun 2021 · 7,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractFree Particle Spin SpeedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe electron and the proton are stable particles, compounds of the atoms, which in turn are the macroscopic scale components. A heated metal plate becomes the source of a cloud of electrons, which by an acceleration in an electromagnetic field becomes an electron beam. Protons are obtained by ionized hydrogen atoms; as the mass of the electron is negligibly small … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 5 Jul 2019 · 7,775 accessesView PDFCite
Review ArticleOpen accessIn the abstractNovel Approach for Characterizing Solid Rocket Motor (SRM)Aliyu Bhar Kisabo, Ngozi Nwokolo, Aliyu Funmilayo Adebimpe, Sholiyi Olusegun SamuelTo characterize SRM, the motor needs to be tested on a static test rig and certain performers indicators evaluated. In this study, the thrust with time from the SRM was acquired via a Digital Acquisition (DAQ) System and saved in Microsoft Excel® format(.csv). These thrust and time of the tested motor were then imported into MATLAB® for the purpose of … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 24 May 2019 · 6,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Real-Time Optimization Approach to the Efficiency of a Photovoltaic System by a Hybrid Tracking Technique using LabVIEWMohamed Redha Rezoug, Rachid ChenniAmong the lines of research on improving the efficiency of a photovoltaic panel, sun tracking techniques occupy a large part. In this article, an extension of Laboratory Virtual Instrument Engineering Workbench (LabVIEW); LabVIEW Interface For Arduino (LIFA) is used. It allows the driving of an Arduino board from LabVIEW, on which a collaboration technique between two categories of pursuit is … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 15 May 2018 · 7,955 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheoretical Analysis and Technical Seismicity Effect Assessment onto the Production Factory due to Traffic in Prešov CityDaniel Papán, Katarína Krkošková, Zuzana PapánováThe technical seismicity effect assessment caused by traffic is the aim of article. The highway structure, as the mine of vibration, includes common layers and also special materials with dumping properties. It is the geomesh reducing the crack creation caused by fatigue, the tension strength increase and excess settlement The stress concentration in the bitumen structure reduces and separates into … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 23 Nov 2017 · 7,113 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectron DimensionsRelly Victoria Virgil Petrescu, Raffaella Aversa, Shuhui Li et al.In this study, the theoretical principles necessary to determine the exact magnitude of a moving electron, depending on the speed of movement, will be exposed. The equations are specifically discussed to determine the radius R of the moving electron, which refers to the electron movement velocity v and the resting mass m0. The mechanical moment of inertia of a sphere … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 7,576 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiomechanically Inspired Shape Memory Effect Machines Driven by Muscle like Acting NiTi AlloysRaffaella Aversa, Francesco Tamburrino, Relly Victoria V. Petrescu et al.The research shows a bioinspired approach to be adopted to design of systems based on Shape Memory Alloys (SMAs), a class of Smart Materials that has in common with muscles the capability to react to an impulse (thermal for SMAs) with a contraction. The biomechanically inspired machine that is discussed in the paper refers to the antagonistic muscles pairs, which … …American Journal of Applied Sciences, Vol. 13, Issue 11 · 24 Nov 2016 · 9,109 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Linear Array Antenna Based on UWB Slot AntennaFaten Ben Ghenaya, Ridha Ghayoula, Ali GharsallahThis paper introduces the novel Ultra-Wide Band (UWB) antennas for UWB applications. We used two different structures, the first is fed by micro-strip line and the second is a compact coplanar waveguide fed planar slot antenna. These designs are a small on planar antenna. The substrate used is FR4 that have the characteristics following: Permittivity εr = 4.4 Impulse Radio … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 25 Mar 2016 · 7,431 accessesView PDFCite
Research ArticleOpen accessIn the abstractRoles of Macroeconomic Variables on Agricultural Diversification in NigeriaSunday B. Akpan, Samuel J. Udoka, Inimfon V. PatrickThe study examined the trend in agricultural diversification index from 1960 to 2014 in Nigeria. It also determined the influence of some macroeconomic variables on the estimated index. Augmented Dickey-Fuller-GLS unit root test showed that all series were integrated of order one. The long-run and short-run elasticity of the agricultural diversification index with respect to the specified macro-economic variables were … …American Journal of Economics and Business Administration, Vol. 7, Issue 2 · 9 Jul 2015 · 7,491 accessesView PDFCite
