Research ArticleOpen accessEvery word in the titleResonance Caused by the Gravitational waves On an Earth SatelliteMohamad RadwanThe present work deals with the motion of an Earth satellite taking into account the oblateness of the Earth and of a passing Gravitational wave. The oblateness of the Earth is truncated beyond the second zonal harmonic, J2, which plays the role of the small parameter of the problem. The conditions for resonance are determined and the resonance resulting from … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 6,769 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVisual Contact between Two Earth’s SatellitesM. E. Awad, M. A. Sharaf, E. H. KhatabProblem statement: In this study, an analytical expression for predicting mutually visible between Earth’s satellites is developed. Approach: A relative satellite-satellite visibility function is developed in terms of orbital elements for two satellites in the same orbital plane. Also, a simple computational algorithm is expressed to compute the visibility function. Results: This study presents a new and easy method to … …American Journal of Applied Sciences, Vol. 9, Issue 5 · 27 Feb 2012 · 6,979 accessesView PDFCite
Research NotesOpen accessIn the abstractMetadata Stewardship and Quality in Telecom SectorBhola Gan Chaudhuri, Shalli RaniThe spread of the telecom network infrastructure, constellations of satellites and the use of the Internet of Things (IoT) have brought about unprecedented volumes of heterogeneous information which facilitate the contemporary monitoring systems of the environment and the earth. Metadata control and information quality have also become significant in the telecom industry in controlling data reliably, enhancing data services, and … …Journal of Computer Science, Vol. 22, Issue 10 · 22 Oct 2026 · 335 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Satellite Custody of Moving Ground TargetsDavid SchusterMaintaining persistent custody of ground targets from Low Earth Orbit (LEO) is a key challenge in space-based surveillance and reconnaissance. Traditional rule-based tasking strategies struggle with scalability as the number of assets and targets grows. In this paper, we present a centralized Reinforcement Learning (RL) approach using Proximal Policy Optimization (PPO) to coordinate four LEO satellites tasked with tracking two … …Journal of Computer Science, Vol. 22, Issue 3 · 25 Mar 2026 · 1,575 accessesView PDFCite
Research ArticleOpen accessIn the abstractCohesion Analysis of Rubber Stand Ages Using Object-Based Image Analysis and Spatial AutocorrelationJiradech Majandang, Suepsai Prasansat, Patiwat Littidej et al.Latex and rubber wood are crucial raw materials used in various industries and play a significant role in the economies of many countries, particularly in tropical regions. Mapping the areas where these materials are planted and classifying the age of rubber stands is important for managing growth assessment, yield assessment, and estimating the number of mature rubber trees that will … …Journal of Computer Science, Vol. 20, Issue 12 · 29 Nov 2024 · 5,293 accessesView PDFCite
Letter to the EditorOpen accessIn the abstractDiscussion on Google Earth Pro SoftwarePedram Jafari ShalkouhiGoogle Earth is a free-of-charge geographic browser that gains images from satellites, the atmosphere, the ocean, and other graphical data by means of the internet. The present letter shows that Google Earth Pro which is known as an updated version of Google Earth cannot present enough information to users. In other words, images provided by Google Earth are more original … …Journal of Aircraft and Spacecraft Technology, Vol. 8, Issue 1 · 27 Feb 2024 · 8,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeolocation System Module Creation to Validate User Location Coordinates in an Android Application Using Flutter FrameworkElmer Matthew Japara, Samsul Arifin, Edy IrwansyahThe target audience for this scientific paper's writing is anyone who is interested in the statistical information that will be used to create a method for determining the separation between two coordinate points. Given that as technology advances, a growing number of applications will make use of geolocation data for economic purposes, such as processing location data to maximize product … …Journal of Computer Science, Vol. 19, Issue 8 · 9 Aug 2023 · 6,378 accessesView PDFCite
Research NotesOpen accessIn the abstractTime-Resolution of Climate Change Monitoring Volcanic Cycles, Stromboli, Ocean Floor Biota and Pandemics (?)Giovanni Pietro Gregori, Gabriele PaparoClimate change is an ongoing, poorly understood and disquieting challenge. The primary drivers are debated. Clear evidence is however suggestive of a time variation of the planetary release of endogenous energy. In fact, soil exhalation is an unprecedented challenge for humankind, as a phenomenon of this kind happens only every 27.40.05 Ma, while human history spans only the last 30,0000 … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 7 Sep 2021 · 6,252 accessesView PDFCite

Research ArticleOpen accessIn the abstractSensing the Hydrogeomorphology and Palaeohydrologic Features of Mars Planet with Inference from the Egyptian Desert: An Insight from Satellite ImagesMohamed YousifThe water access in any planet of the universe can be considered a crucial evidence for life existence. The study of Mars has special importance where it has a complex preserved geological record of a time period longer than on Earth. Many regions of Mars planet are subjected to observations through the obtained satellite images in comparison to similar areas … …Space Science International, Vol. 4, Issue 1 · 27 Apr 2020 · 13,200 accessesView PDFCite
