Nowadays high energy physics scientists build and design systems that are complex in terms of the huge amount of subsystems and individual components. A single subsystem may consist of a few tens of thousands digital and analogue channels and sensors. As a result, the data rates captured in modern systems may result in gigabytes per second. Complex systems could generate various alarms and provide...
This paper describes a novel Polyhedral Source-to-Source Compiler (PSSC) that enables automatic recognition of parallel regions of C/C++ code and annotating them with OpenMP/OpenACC pragmas. The proposed source-to-source compiler uses polyhedral model to detect and optimize parallel loops. Loop optimization is done on intermediate code representation by Polly compiler and then it is mapped to original...
European XFEL project developed in Hamburg by Deutsches Elektronen-Synchrotron contains a linear accelerator capable of generating light pulses at extremely short wavelengths, which will enable observing short lasting phenomena at atomic scale. Mode-locked lasers are commonly used in such facilities. Laser diode driver (LDD) is a significant element in the beam monitoring system, which will be used...
The paper presents a module for acquisition of stereoscopic image through SDI interface, designed for Registration of Stereoscopic Image project. As a component of an upgradable FPGA-based system for rapid calibration of 3D camera rigs, the module serves the purpose of acquiring an SDI stream from a set of two cameras and outputting it to either a dedicated SDI output or an HDMI output after processing...

The photovoltaic (PV) module efficiency depends inversely on its temperature. The PV-module temperature is a function of a few factors, and the ambient (air) temperature is one of the most significant, therefore greatly influencing the amount of produced electric energy. Therefore, in summer periods the temperature is the least favorable for photovoltaics. This paper presents the simulation results...
Thermal issues in today's VLSI circuits are under intensive research due to technology scaling and increasing power density. Nowadays, more than a half of IC failures is caused by exceeded heating of a semiconductor structure. Therefore, it is necessary to constantly develop accurate methods capable of predicting temperature profile inside the chip structure. We propose a model to obtain variation...
The paper presents results of studies on piezoelectric generators, in which energy of mechanical vibrations is harvested and converted to electric energy. These piezoelectric generators were proposed, as an alternative to a battery-based solution, for powering of sensor nodes in condition monitoring systems of large rotary machines such as turbogenerators in power plants. Since a performance of three...
