Mineral dressing, especially metal minerals in Indonesia, is carried out using appropriate methods based on their properties and characteristics. The method often used gravity concentration. technology that makes use of it a shaking table. This tool works the difference specific pаrtіcle size flowing film concentration which exerts thrust against pаrtіcles deck. In an effort to meet needs pract...

parallel computing is a topic of interest for a broad scientific community since it facilitates many time-consuming algorithms in different application domains.in this paper, we introduce a novel platform for parallel computing by using mpi and openmp programming languages based on set of networked pcs. umzhpc is a free linux-based parallel computing infrastructure that has been developed to cr...

workspace analysis is one of the most important issues in the robotic parallel manipulator design. ‎however, ‎the unidirectional constraint imposed by cables causes this analysis more challenging in the cabledriven redundant parallel manipulators. controllable workspace is one of the general workspace in the cabledriven redundant parallel manipulators due to the dependency on geometry parameter...

An automatic geomagnetic station for monitoring the Earth’s magnetic field variations was installed in December 2020 at Talos Dome, a remote site on Antarctic Plateau, about 300 km away from permanent observatory Mario Zucchelli Station (MZS). Designed and assembled laboratory of electronics Istituto Nazionale di Geofisica e Vulcanologia (INGV) Rome, this autonomous is formed by vector magnetom...

This paper considers the problem of detecting rogue base station in WiMAX/802.16 networks. A rogue base station is an attacker station that duplicates a legitimate base station. The rogue base station puzzles a set of subscribers who try to get service which they believe to be a legitimate base station. It may lead to disturbance in service. The strategy of attack depends on the type of network...

We study a dynamic allocation problem that arises in various scenarios where mobile clients joining and leaving the system have to communicate with static stations via radio transmissions. Restrictions are a maximum delay, or laxity, between consecutive client transmissions and a maximum bandwidth that a station can share among its clients. We study the problem of assigning clients to stations ...
