Research ArticleOpen accessIn the abstractThinging-Based Conceptual Modeling: Case Study of a Tendering SystemSabah Al-Fedaghi, Esraa HaidarIn computer science, models are made explicit to provide formality and a precise understanding of small, contingent “universes” (e.g., an organization), as constructed from stakeholder requirements. Conceptual modeling is a fundamental discipline in this context whose main concerns are identifying, analyzing and describing the critical concepts of a universe of discourse. In the information systems field, one of the reasons … …Journal of Computer Science, Vol. 16, Issue 4 · 15 Apr 2020 · 7,943 accessesView PDFCite
Research ArticleOpen accessIn the abstractA 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 PDFCite
Review ArticleOpen accessIn the abstractAn 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
Review ArticleOpen accessIn the abstractNASA has Found the Most Distant Black HoleRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuScientists have uncovered a rare relic from the early universe: the farthest known supermassive black hole. This matter-eating beast is 800 million times the mass of our Sun, which is astonishingly large for its young age. Researchers report the find in the journal Nature. "This black hole grew far larger than we expected in only 690 million years after the … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,292 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout Robotics, Mechatronics and Automation that Help us Conquer the Cosmic SpaceRelly Victoria Virgil PetrescuHere we have to mention that all these SF writings and many others that have existed over time, especially in the 20th century, have influenced alongside obvious screenings, young people and not just them, to think more about our role, robots, into a better world. The robot's key role is to help the man make his work easier, safer, more … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 6 May 2019 · 6,745 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnder WaterRaffaella Aversa, Relly Victoria Petrescu, Antonio Apicella, Florian Ion Tiberiu PetrescuWith a 361 million square Km surface and a volume of 1370 million of cubic kilo, world seas and oceans have represented and still remain the privileged space for living species evolution. Other than being the 70% of the Earth surface, water environment, contrary to the terrestrial one where life essentially develops in 2 dimensions, is a 3D fully volume … …OnLine Journal of Biological Sciences, Vol. 17, Issue 2 · 10 Jun 2017 · 7,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Elite Pool-Based Big Bang-Big Crunch Metaheuristic for Data ClusteringIbrahim Al-Marashdeh, Ghaith M. Jaradat, Masri Ayob et al.This paper delves into the capacity of enhanced Big Bang-Big Crunch (EBB-BC) metaheuristic to handle data clustering problems. BB-BC is a product of an evolution theory of the universe in physics and astronomy. Two main phases of BB-BC are big bang and big crunch. The big bang phase involves a creation of a population of random initial solutions, while in … …Journal of Computer Science, Vol. 14, Issue 12 · 19 Jun 2018 · 7,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn a New Equation for the Design and Development of Space Launch VehiclesZaheen Abdur RahmanIt is a general consensus amongst the global scientific community that space is the final frontier for human exploration. It has also been reasoned by them that in order to survive in this hostile universe, humanity has to become a multi-planetary species. For that reason, according to calculations made after mapping the human genome, over 10,000 people are needed to … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 26 Feb 2018 · 7,410 accessesView PDFCite
Review ArticleOpen accessIn the abstractStructure of Buried Ice on MarsRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuAfter the older evidence that there is carbon dioxide on Mars made up of oxygen 2 and carbon now we have evidence that there is even normal water on the marble consisting of hydrogen 2 and oxygen. In other words, we have Martian oxygen combined with carbon and hydrogen, so we can extract oxygen directly to the site to initially … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 22 Jan 2018 · 7,212 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA Data Used to Discover Eighth Planet Circling Distant StarRelly Victoria Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuDiscovering the origins of life and colonizing extraterrestrial planets are two of the greatest ambitions that the international scientific community has today. Today, NASA is more prepared than ever to embark on an unprecedented race to conquer other worlds. The Kepler mission, named after Johannes Kepler, the German astronomer of the 16th-17th centuries, was scheduled to begin on March 7, … …Journal of Aircraft and Spacecraft Technology, Vol. 2, Issue 1 · 18 Jan 2018 · 7,904 accessesView PDFCite
