The Micro Telecommunications Computing Architecture (MTCA) standard is a modern platform, that is gaining popularity in the area of High Energy Physics (HEP) experiments. The standard provides extensive management, monitoring and diagnostics functionality. The hardware management is based on the Intelligent Platform Management Interface (IPMI), that was initially developed for management and monitoring...
Fast evolution of high-performance cameras in recent years has made them promising tools for observing transient and fast events in large-scale scientific experiments. Complex experiments, such as ITER, take advantage of high-performance imaging system consisting of several fast cameras working in the range of visible and infrared light. The paper presents a first implementation of complete image...
The distributed data acquisition and control systems in large-scale scientific experiments, like e.g. ITER, require time synchronization with nanosecond precision. A protocol commonly used for that purpose is the Precise Timing Protocol (PTP), also known as IEEE 1588 standard. It uses the standard Ethernet signalling and protocols and allows obtaining timing accuracy of order of tens of nanoseconds...
The computation speed offered by nowadays embedded systems allows combining advanced signal processing and data acquisition in dedicated architectures optimized for given applications. Such architectures can be used for 2D/3D signal analysis and reconstruction in such broad areas as: medical signal processing - tomography object reconstruction (USG, PET, CT, OCT, etc.), biomedical image analysis -...
This paper studies hot spot and thermal coupling problems in future multicore architectures as CMOS technology scales from 65 nm feature size to 15 nm. We demonstrate that the thermal coupling between neighboring cores will dramatically increase as the technology scales to smaller feature sizes. The simulation studies were based on solving the heat equation using the analytical Green's function method...
The Advanced Telecommunications Computing Architecture (ATCA) standard describes a powerful platform, implementation of which is considered to be adopted as a base for the control system of the X-ray Free Electron Laser (X-FEL), being built at Deutsches Electronen-Synchrotron (DESY) in Hamburg, Germany. The Low Level Radio Frequency (LLRF) control system is composed of a few ATCA Carrier Boards. Each...
The main goal of this article is to show a new approach to software development and integration. Article shows how Service Oriented Architecture can change the way of business and IT cooperation. Based on BPEL language Document Management System illustrates how easily business people can change business logic of application without any special technical knowledge.
The linear particle accelerators use superconducting cavities working with high operating gradients. The electromagnetic wave, transferred to the cavity as a set of successive pulses, causes mechanical stresses inside the cavity. Therefore, the resonance frequency of the cavity is significantly modulated, which may lead to cavity detuning in range of hundreds of Hz. The piezoelectric actuators are...
The downsizing of transistor dimensions enabled in the future nanotechnologies will inevitably increase the number of faults in the complex ULSI chips. To maintain the production yield at acceptable level, several levels of protection mechanisms will have to be implemented to tolerate the permanent and transient faults occurring in the physical layers. In this paper, we study fault tolerance at the...
Mobile phones market has become one of the most important industry in United Kingdom. In recent years mobile phones have gained more and more popularity and the number of their sales is still increasing. This success is caused by a few reasons. First of all, mobile phones enable people to communicate easily all over the world. Secondly, modern mobile phones provide additional features that make them...
