The tragic Deepwater Horizon accident in the Gulf of Mexico in 2010 as well as the increase in deepwater offshore activity have increased public interest in counter-measures available for sub-surface releases of hydrocarbons. To arrive at proper contingency planning, response managers urge for a system for instant detection and characterization of accidental releases. Along these lines, this paper...
Detecting epileptic electroencephalography (EEG) signals, both automatically and accurately, is significant in ambulatory long-term monitoring patients with epilepsy. In this study, it is presented a novel epileptic-like event detection algorithm based on a mixture of amplitude, frequency and spatial analysis with rule-based decision. In this work, EEG signals from 6 different subjects were searched...
ITER CODAC Design identified the need for two types of Plant System. Slow control plant system, based on industrial automation technology with maximum sampling rates below 100 Hz, and fast control plant system based on embedded technology with higher sampling rates and more stringent realtime requirements. The latter is applicable to diagnostics and Plant Systems in closed-control loops whose cycle...
The Multithreaded Application Real-Time executor (MARTe) software provides an environment for the hard realtime execution of codes while leveraging a standardized algorithm development process. The Experimental Physics and Industrial Control System (EPICS) software allows the deployment and remote monitoring of networked control systems. Channel Access (CA) is the protocol that enables the communication...
Data acquisition on the ISTTOK tokamak is being upgraded from VME to PCI using a general purpose especially developed transient recorder PCI acquisition board with 8 galvanic isolated 14 bit, 2 MSamples/sec channels, 512 Mbytes of SDRAM, and integrated FPGA/DSP capabilities. Due to the wide range of ISTTOK signal spectrum, data-reduction is crucial to efficiently use data retrieval and analysis systems...

Eight independent multi-rate signal interpolators, with real-time change of rate capability, were implemented on a field programmable gate array. The interpolator main building blocks are a cascaded integrator-comb (CIC) filter and the respective compensation filter. The latter performs a fixed rate change of 4 and was implemented as a 129 taps finite impulse response (FIR) filter. The FIR filter...
The need to control in real-time the plasma parameters in fusion devices leads to the development of algorithms requiring intensive computation and providing results on a few hundred microseconds. The present paper's objective was the implementation of the current filaments method (CF) to model in real-time the ISTTOK plasma shape and position. The hardware used was the on site developed PCI-TR-256...
