Review ArticleOpen accessPhrase in the titleUnveiling the Future: A Survey of Electric Propulsion Systems and their Pivotal Role in Shaping the Next Frontier of Space ExplorationJinadu Abdulbaqi, Okikijesu Omolona Olajide, Ayodeji Tunde AkangbeElectric propulsion represents the future of space travel, which is a promising technology for Earth-orbital and deep space missions, including potential applications in human Mars missions. The past decade has witnessed substantial progress in the conceptualization and experimentation of electric thrusters and their propellants, signaling a transformative era in space exploration. This review provides an overview of the comparison between … …Journal of Aircraft and Spacecraft Technology, Vol. 7, Issue 1 · 10 Jan 2024 · 6,851 accessesView PDFCite
Research ArticleOpen accessIn the abstractLess Biased Approach for Sandstone Pore SegmentationDaffa Abiyyu Murtadha Kurnia, Iman Herwidiana KartowisastroReservoir characterization is a fundamental process in estimating reserves within petroleum and hydrogeological systems, where the precise determination of pore space dictates the validity of fluid flow models. Although X-Ray Computerized Tomography (XRCT) has become the standard non-destructive evaluation method for visualizing the internal structure of rocks, the data interpretation process still faces challenges during the image segmentation stage. Conventional … …Journal of Computer Science, Vol. 22, Issue 6 · 15 Jun 2026 · 1,196 accessesView PDFCite
Technical ReportOpen accessIn the abstractMagnetic Fusion Plasma DriveFlorian NeukartIn the evolving realm of space exploration, efficient propulsion methods are paramount to achieve interplanetary and possibly interstellar voyages. Traditional propulsion systems, although proven, offer limited capabilities when considering longer-duration missions beyond our immediate cosmic vicinity. This study introduces and thoroughly investigates the Magnetic Fusion Plasma Drive (MFPD) propulsion system, a novel fusion-powered propulsion mechanism. Through rigorous theoretical underpinnings and … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 2 · 4 Mar 2024 · 7,189 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,371 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Clustering using Two-Stage Eagle Strategy Based on Slime Mould AlgorithmRachid Oucheikh, Achraf Touil, Mouhsene FriDataclustering is considered an important component of data mining which aims tosplit a given dataset into disjoint groups having the same similarities. Thedeveloped techniques for clustering have some challenges to cluster entities incomplex search space and most of them aim to maximize the sum of inter-clusterdistances and minimize the sum of intra-cluster distances. This objectivefunction is nonlinear and hard to … …Journal of Computer Science, Vol. 18, Issue 11 · 7 Nov 2022 · 5,795 accessesView PDFCite
Research ArticleOpen accessIn the abstractImproving the Exploration Strategy of an Automated Android GUI Testing Tool based on the Q-Learning Algorithm by Selecting Potential ActionsGoh Kwang Yi, Salmi Binti Baharom, Jamilah DinResearchers have proposed automated testing tools to minimise the effort and resources spent on testing GUIs. A relatively simple strategy employed by the proposed tools thus far is the observe-select-execute approach, where all of a GUI’s actions on its current state are observed, one action is selected and the selected action is executed on the software. The strategy’s key function … …Journal of Computer Science, Vol. 18, Issue 2 · 2 Mar 2022 · 6,787 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrajectory Optimization for First Human Asteroid Exploration MissionAtiksha Sharma, Santosh KosambeAfter the successful completion of robotic expeditions on Mars, an ultimate goal was set for space fairing nations and agencies around the world to send astronauts to Mars by 2030. Unfortunately, a mission to Mars would last upwards for years meanwhile several asteroids fly close to the Earth. A manned trip to an asteroid would be a valuable stepping stone … …Journal of Aircraft and Spacecraft Technology, Vol. 4, Issue 1 · 8 Aug 2020 · 6,435 accessesView PDFCite
Case ReportOpen accessIn the abstractRetroperitoneal Hydatid Cyst Masquerading as a Retroperitoneal Cystic TumorK. Hemanth Kumar, Anish Choudhary, Amaresh Aruni, N.V.K.N. KarthikHydatid disease is an endemic disease, with canines the primary host and humans the intermediate host. Liver, spleen and lungs are most common involved organs, but it can involve any organ. Retroperitoneal hydatid cyst are categorised into two types, primary and secondary. Primary retroperitoneal hydatid cyst is rare disease, with most of the cases diagnosed intra-operatively, hence pre-operative high index … …American Journal of Infectious Diseases, Vol. 15, Issue 3 · 29 Aug 2019 · 7,269 accessesView PDFCite
Review ArticleOpen accessIn the abstractNASA’s Exploration Missions to the Red PlanetSantosh KosambeThe exploration missions to the red planet were started in 1960 by the Soviet Union, since then the planet has gain attention of all the scientists and explorers worldwide. Several exploration missions have been launched by the space organizations and nations to explore the Martian surface. NASA launched its first exploration mission to Mars in 1964 in the form of … …Journal of Aircraft and Spacecraft Technology, Vol. 3, Issue 1 · 6 Jul 2019 · 6,973 accessesView PDFCite
Review ArticleOpen accessIn the abstractAbout the Space RobotsRelly Victoria Virgil PetrescuToday, robots help us more than ever in all major operations, everyday life and become a daily reality, making it an integral part of major human projects. If they are still the majority in the machine industry, they will soon become as many in other industries and at the same time will grow strongly for human support in conquering extraterrestrial … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 25 May 2019 · 6,969 accessesView PDFCite
