Research ArticleOpen accessIn the abstractPresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstructing Gibbs Measure in a Rigorous WayFarida Kachapova, Ilias KachapovEquilibrium statistical mechanics studies mathematical models for physical systems with many particles interacting with an external force and with one another. In this paper we describe an interaction model that generalizes several of these models in one model. An infinite model is constructed as the limiting case of finite interaction models, that is as a thermodynamic limit. The key point … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Oct 2019 · 6,591 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew About the Balancing of Thermal MotorsNicolae Petrescu, Florian Ion Tiberiu PetrescuThe paper presents a new method of balancing the thermal motors, the method that perfectly fits the engines with modern internal combustion. This new constructive method imposes a new in-line engine design in order to better balance it, thus achieving a static balancing and total dynamics of the new type of internal combustion heat engine. The method can also be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 Jul 2019 · 5,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfrared Thermography for the Characterization of Painted Vaults of Historic Masonry BuildingsClaudia Casapulla, Alessandra Maione, Luca Umberto ArgientoThe infrared thermography is a type of non-destructive investigation which can find interesting application in acquiring information about the structural features of ancient masonry buildings. In this case, in fact, the needs of preservation of the historical values have to be compound with the needs of achieving a proper level of knowledge of the parameters influencing the structural behaviour in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 2, Issue 1 · 20 Feb 2018 · 7,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometry and Determining the Positions of a Plan Transporter ManipulatorRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.The conveyor mechanism (working in a plan) to be presented in this study is a classic case of manipulating conveyor, simply with a single degree of mobility. It is a very common mechanism used in classical mechanics, being encountered at lifting platforms, at handicapped chairs, at cranes, forklifts, automatic machines and machines, or at older steam locomotives where it having … …Journal of Mechatronics and Robotics, Vol. 1, Issue 2 · 1 Jan 2018 · 6,551 accessesView PDFCite
Review ArticleOpen accessIn the abstractSome Special AircraftRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.In this study, the authors want to present a few more distinct aircraft from a constructive and functional point of view. Their role has often been determined by the need to achieve or fulfill certain more or less strategic objectives. Such ships will also be built in the future more and more often in order to be able to respond … …Journal of Aircraft and Spacecraft Technology, Vol. 1, Issue 3 · 19 Aug 2017 · 7,458 accessesView PDFCite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDFCite
Research ArticleOpen accessIn the abstractMeasuring the Operating Efficiency of Solar Cell Companies in Taiwan with Data Envelopment AnalysisJui-Min HsiaoThis study discusses the Data Envelopment Analysis (DEA) approach to measure the operating efficiency of solar cell companies. With active and constructive advancement of the government, competition in the solar cell industry became even tenser. When drawing up the competitive strategies, one firm should identify the key indicators of its operating efficiency. This study incorporates three inputs (the number of … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 7 Nov 2012 · 6,920 accessesView PDFCite
Research ArticleOpen accessIn the abstractController Based Observer in Switched System with Norm Bounded UncertaintyMongi Besbes, Elyes MaherziProblem statement: This study discusses the robust stabilization of norm bounded discrete switched systems. Approach: The proposed method is using the second Lyapunov approach and the poly-quadratic function concept. The stabilization conditions are written through linear matrix inequality relations. The control law is based on a static output feedback with the use of a switched observer. The synthesis conditions of … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 11 May 2012 · 6,904 accessesView PDFCite
