High Performance Computing (HPC) facilities serve as infrastructure for solving demanding computational problems met in various domains. HPC involves expensive resources both material and operational. Therefore, leveraging its operation at his peak capacity is very important from economic efficiency perspective. Nowadays, it is very difficult for a regular researcher that needs HPC services to have...
With the rapid increase of image sensors resolution, some pressure moved on compression algorithms again. Fractal compression is known to provide good performance in terms of compression ratio. But more than ever, the focus is on execution time of these algorithms. Large and fast access memories are hard to provide and very expensive. Therefore, a fast compression algorithm can reduce the expensive...
Many domains like deep learning, machine learning, and computational finance uses GPU's for decreasing the execution time. GPUs are widely used in data centers for high performance computing where virtualization techniques are intended for optimizing the resource utilization (e.g. GPU cloud computing). However, these data centers have some downsides like energy consumption and acquisition cost.
Nowadays an extensive attention is given to UAVs and their applications. One applications category can be underserved by hybrid systems composed from UAV and ground WSN. UAV can gather data from ground WSN which, at its turn could be initially deployed by the UAV itself. Ground nodes are limited in battery life, therefore, an efficient communication algorithm will improve their energy autonomy. This...
This article submits an architecture for supporting decentralized control. The focus is on optical bus as a solution to overcome the main disadvantages of decentralized control. Even though decentralized control is mediated as being a better solution than centralized one, we continue to find centralized control in practice. One reason is the bottleneck introduced by the field bus communication between...
The paper presents a novel architecture based on frequent utilization of PDAs and mobile phones as human machine interface (HMI) in controlling various systems. There are two main considerations discussed. One is with regards to real-time constraints in the context of industrial process control. The second is the possibility of transferring some tasks from the process controller towards the Android...
For a class of affine systems with stable system matrix and oscillating behavior, the control objective consists of oscillations damping while tracking a piecewise constant reference signal. Under some controllability assumptions, a control solution consists of a pole assignment procedure combined with the internal model principle. The paper discusses, within a simulation experiment, a possible extension...
