Research ArticleOpen accessA Hypothesis Which Supports the Possibility of the Existence of Dark Matter with Negative MassFlorian Ion Tiberiu PetrescuThe paper presents an algorithm for calculating the negative mass of an atomic electron, a fact that from a physical point of view shows the possibility of the existence of the matter with the negative mass that could constitute the dark matter that separated from the normal matter with the positive mass due to the huge masses of different matter … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 Jan 2020 · 7,918 accessesView PDF Cite

Research ArticleOpen accessStructure of a Photovoltaic Electric LocomotiveFlorian Ion Tiberiu PetrescuThe paper proposes to start studies at the global level for the implementation of photovoltaic electric locomotives. The question the author asks is why such trains have not been implemented so far, is there no interest in such a thing? This may avoid the current rush to implement 5G technologies in an already extremely dangerous form for humanity, the rush … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 16 Nov 2019 · 7,191 accessesView PDF Cite

Review ArticleOpen accessThe Energy of the Sea Must Begin to be Massively ExtractedNicolae Petrescu, Florian Ion Tiberiu PetrescuThe present paper is intended to be a plea for the extraction of energy from the seas and oceans because this energy is very large quantity from an objective point of view and in addition it is clean, renewable and sustainable, friendly and totally non-dangerous, being a very high energy which it is permanently lost, energy from which if we … …Energy Research Journal, Vol. 10, Issue 1 · 21 Oct 2019 · 6,971 accessesView PDF Cite

Review ArticleOpen accessPermanent Magnetic FluidsNicolae Petrescu, Florian Ion Tiberiu PetrescuA team of researchers at the University of Massachusetts Amherst has accidentally obtained the first magnetized permanent liquid in the world, the droplets of this liquid moving in unison and able to associate in different forms while being manipulated exterior by means of a magnet, according to a new study published in the latest issue of the journal Science, reports … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 3 · 22 Aug 2019 · 8,842 accessesView PDF Cite

Research ArticleOpen accessEnergy Sources TodayNicolae Petrescu, Florian Ion Tiberiu PetrescuThe paper intends to go through some major energy sources that need to be further developed in order to provide the energy needed for an indefinite period of time. It is proposed that both water and solar energy, as well as wind energy together with nuclear energy, are important, but other modern energy sources capable of generating energy directly or … …Energy Research Journal, Vol. 10, Issue 1 · 21 Aug 2019 · 6,862 accessesView PDF Cite

Research ArticleOpen accessSome Aspects of the Human Body’s HydraulicsRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThis paper presents some aspects related to the human body’s hydraulics in the desire to make readers aware of how to maintain all the blood vessels of the human body in order to maintain the entire healthy, functional, young, vigorous circulatory system for a while the longest possible. The problem is complex because it has to be viewed from all … …OnLine Journal of Biological Sciences, Vol. 19, Issue 3 · 9 Aug 2019 · 7,178 accessesView PDF Cite

Research ArticleOpen accessNew 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 PDF Cite

Research ArticleOpen accessFree 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 PDF Cite

Research ArticleOpen accessMachine Motion Equations Presented in a New General FormatNicolae Petrescu, Florian Ion Tiberiu PetrescuConsidering the increased importance of robots nowadays, when no large factory or factory can work without robots, we want to present in the work the motion equations of the machine in an original form, both in terms of aspect and their deduction. The machine's motion equations can be used in dynamic calculations at any type of machine, whether it be … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 22 May 2019 · 6,131 accessesView PDF Cite

Review ArticleOpen accessThe Yield of the Thermal EnginesNicolae Petrescu, Florian Ion Tiberiu PetrescuThis paper presents an algorithm for determining the dynamic parameters of the main classic mechanism of internal combustion engines. It shows the distribution of forces (on the main engine mechanism) to internal combustion engines. With these forces and together with the kinematic coupling speeds, the efficiency of the thermal engine is determined. The method applies separately for two distinct situations: … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 14 May 2019 · 6,191 accessesView PDF Cite
