Abstract: Simultaneous Localization and Mapping (SLAM) is a core capability for autonomous robots, drones, and embedded vision systems, but its front-end processing—including sensor data acquisition, feature extraction, and data association—demands high computational throughput with strict power constraints. This paper presents an energy-efficient FPGA-based architecture for SLAM front-end processing, optimized for real-time performance.....

Key Words: Energy-efficient computing, FPGA architecture, SLAM front-end, real-time processing, hardware acceleration, embedded systems, feature extraction, low-power design, parallel processing, autonomous navigation.

Abstract: The reliable operation of power systems cannot be achieved without efficient and precise operation and maintenance methods. Based on the problems existing in actual operation and maintenance, and starting from the demand orientation, this paper focuses on the characteristics of low efficiency, reliance on judgment experience, and uncertainty of manual inspection in substations, and proposes a target detection method based on deep learning and YOLOv7. This method is an improvement on the traditional target detection. Through ablation and comparison experiments, the improved model can enhance detection accuracy, reduce the network model, and increase detection speed compared with the traditional model.....

Abstract: ZnS thin films were synthesized on varying molar concentrations (MC) (0.05-0.20M) using Chemical Bath Deposition (CBD) technique and studied the growth surface morphology, crystal structures and optical properties using FESEM, XRD and UV-vis-spectrophotometer. The surface structures were observed with regular distribution of ZnS nanoparticles with particle sizes 6.7nm – 11.54nm and were confirmed with XRD results. The crystal growth showed depended on molar concentration of Zn+2 and S-2 ions. Maximum peak in the XRD spectra....

Abstract: Background: Satellite communication systems operating at microwave and millimeter-wave frequencies are significantly affected by atmospheric propagation impairments, particularly rain attenuation. As Mongolia plans to launch its national satellite communication infrastructure at the 113.6°E geostationary orbital position, accurate estimation of rain-induced signal degradation becomes essential for reliable link design and system planning. Materials and Methods: This study evaluates rain attenuation for satellite communication links across Mongolia using internationally standardized propagation models recommended by the International Telecommunication Union Radiocommunication Sector (ITU-R). The....

Abstract: In contemporary electric drive systems, where high efficiency, lower current consumption, and enhanced torque output are crucial, the design and performance optimization of three-phase induction motors for traction applications have grown in importance. The results of this study's application of the multi-objective optimization (MOO) approach to induction motor design are contrasted with those of conventional motor design, single-objective optimization (SOO), and experimental measurements. Important performance metrics, such as output power, torque, efficiency..

Abstract: The goal of this work is to show how to design and build a mobile robotic rover that has a controlled electromagnetic pulse (EMP) unit built in. This will help reduce threats from a distance in dangerous places. The main goal of the system is to limit the length of time that people are exposed to dangerous situations by making it possible for a robotic rover with a two-degree-of-freedom (2-DOF) robotic arm to work wirelessly. EMP may hit the target with perfect accuracy with the arm. The system uses microcontrollers to control the movement of the rovers, the activation of the arms, and the triggering of EMP.......
