The growing demand for high-efficiency electric propulsion systems in modern satellite missions has intensified interest in alternative propellants for Hall-effect thrusters (HETs). Although xenon remains the standard propellant due to its favorable atomic mass and low ionization energy, its high cost and limited global supply motivate the exploration of viable substitutes such as krypton and argon. This study presents a comprehensive comparative analysis of noble gas propellants for Hall…

This tutorial review provides a comprehensive exploration of advanced Structured Query Language (SQL) techniques, building upon foundational database knowledge to equip aspiring programmers and administrators with sophisticated data management skills. The review covers ANSI SQL standards applicable across major database management systems, including Oracle, SQL Server, and MySQL [1, 4]. Key topics include the intricate use of aggregate functions for data summarization and statistical…

This report presents a comprehensive study on the implementation and simulation of advanced flight control systems for Unmanned Aerial Vehicles (UAVs). The work is divided into two primary domains: the practical application of the Pixhawk Pilot Support Package (PSP) within the MATLAB/Simulink environment and the theoretical construction of a six-degree-of-freedom (6 DOF) dynamic model for fixed-wing aircraft. By leveraging the PSP, we demonstrate the integration of hardware-in-theloop (HIL)…

Telemetry data that reflects the operational condition of onboard subsystems is continuously produced in vast quantities by satellite systems [1, 5]. For ensuring satellite reliability and preventing system failures, it is necessary to identify unusual trends in this data. Telemetry signals are frequently difficult for conventional anomaly detection techniques to handle because of their complicated temporal and multidimensional character. This study suggests a multimodal deep learning…

Over the past 15 years, the open data movement has transformed from a niche policy initiative into a global phenomenon that touches nearly every aspect of modern society. This paper presents a comprehensive content analysis of open data research published in peer-reviewed journal articles from 2010 to 2025. Through systematic review and thematic analysis, we trace the evolution of open data research across five distinct periods: Foundation (2010-2012), Growth (2013-2016), Maturation…
