Research ArticleOpen accessEvery word in the titleModern Propulsions for Aerospace-Part IIRelly Victoria Virgil Petrescu, Raffaella Aversa, Bilal Akash et al.Speaking about a new engine ionic means to speak about a new aircraft. The paper presents in a short time the actual engines ion chambers (called the ion thrusters) and other new ionic motors proposed by the authors. The engine (ionic propulsion unit of ions, that accelerates the positive ions through a potential difference) is approximately ten times more efficient … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 1 · 25 Apr 2017 · 8,118 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExperimental Study of Particle Emissions from a Modern 5 kW Pellet StoveIgor V. Dyakov, Benjamin Bergmans, Svend Bram et al.This work is dedicated to the determination of the particle emission from a commercially available bottom feed 5 kW pellet stove. Two-stage dilution was applied to provide the operational stability and conditioning of the sample. The analysis of particle emission was performed by means of the Electrical Low Pressure Impactor with 14 stages, able to separate particles from 0.006 to … …Energy Research Journal, Vol. 7, Issue 2 · 25 Oct 2016 · 6,998 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGRAPHSJ 3: A MODERN DIDACTIC APPLICATION FOR GRAPH ALGORITHMSGianluca Costa, Claudia D’Ambrosio, Silvano MartelloIn 2009 the authors developed an open source Java application and framework, GraphsJ, to help the students in their approach to the study of graph algorithms, by guiding them to understand their logical structures through experiments on numerical instances. After four years, the availability of Java 7 and of new tools suggested the implementation of a new major release. We … …Journal of Computer Science, Vol. 10, Issue 7 · 10 Feb 2014 · 7,857 accessesView PDFCite

Research ArticleOpen accessIn the keywordsAbout Aircraft's New Power and PropulsionRelly Victoria Virgil Petrescu, Florian Ion Tiberiu PetrescuEven though the current classical methods of aerospace propulsion are much improved, some of the most modern methods have already been introduced, including propulsion with electric motors. Energy can be obtained from hydrogen burners, honeycomb burners to protect the combustion of hydrogen that burns 10 times faster than conventional fuels or alcohols. Hydrogen storage is also done in honeycomb cell … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 5 Mar 2020 · 7,325 accessesView PDFCite
Review ArticleOpen accessIn the keywordsAn Exoplanet has Smothering Stratosphere without WaterRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuIn some earlier works, the authors of the present study have shown that a modern ship should resemble a UFO, an accelerated particle jet propulsion with a particle accelerator on board the ship, accelerating to the very best big. The problem as an idea is clear and simple, but the current technologies we have in the field of fixed particle … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 6,995 accessesView PDFCite
Research ArticleOpen accessIn the keywordsThe Role of Developmental Psychology to Understanding History, Culture and Social ChangeGeorg W. OesterdiekhoffDevelopmental psychology of the past generations has evidenced that the whole pre-modern humankind stood on pre-operational or concrete-operational stages. Only the modern humankind has also developed the fourth stage of human development, the adolescent stage of formal operations. Lew Vygotski was 1933 one of the first to earmark convincingly the connection of socialisation (school education) and cognitive development as a … …Journal of Social Sciences, Vol. 10, Issue 4 · 29 Jan 2015 · 12,911 accessesView PDFCite
