Discrete-Time Cellular Neural Networks Implemented on Field-Programmable Gate-Arrays to Build a Virtual Sensor System

Image processing is one of the popular applications of Cellular Neural Networks. Macro enriched field-programmable gate-arrays can be used to realize such systems on silicon. At first glance a pipelined approach, based on circuit switching, seems promising. The digital implementation supports the handling of grey-level images at 180 to 240 Mpixels per second by exploiting the Xilinx Virtex-II macr

Industrial energy efficiency improvement – the role of policy and evaluation

Popular Abstract in Swedish Industrin i Sverige och i många andra länder står för en stor del av samhällets energianvändning och energi utgör en nödvändig insats i industrins processer och förädling av produkter. Industriell tillverkning sysselsätter dessutom många arbetstagare både direkt och indirekt i utbytet med övriga delar av samhället och ekonomin. Samtidigt medför energianvändning och relaAt EU and to a varying degree at Member State (MS) level, industrial energy efficiency improvement (EEI) is considered an attractive means for reaching political objectives of different dimensions, not least environmental. For energy-intensive manufacturing industry in particular, EEI can lead to cost reductions, improved profitability and competitiveness. However, research and other analyses show

Interactive Tools for Education in Automatic Control

Experiments have shown that the time is now ripe for a new generation of interactive learning tools for control. The tools are based on objects which admit direct graphical manipulation. During manipulations, objects are updated instantaneously, so that relations between objects are maintained all the time. The tools are natural complements to traditional education, and allow students to quickly g

Functional activation of the frontal lobes. Regional cerebral blood flow findings in normals and in patients with frontal lobe dementia performing a word fluency test

The present study examined the utility of the Word Fluency Test (WFT) as a frontal-lobe-activating test in brain imaging. Regional cerebral blood flow (rCBF) was measured during rest and during the WFT in 49 healthy volunteers and in 15 patients with frontal lobe dementia (FLD). The results showed a highly significant frontal lobe activation in 85% of the normal subjects. This finding was not rela

Approximating a Post-Contingency Stable Operation Region in Parameter Space through Time-Domain Simulation

Operating criteria for power systems, such as theN−1-criterion, are often based on evaluating whether the system is vulnerable to a specific set of contingencies. Therefore, a major part of power system security is concerned with establishing regions in parameter space where the system is vulnerable to specific contingencies. In this article we exploit the possibility of using Monte Carlo simulati

Do lighting control and user interface design matter to occupant behaviour? The case of optimal lighting use in non-residential buildings

Popular Abstract in Swedish Att reducera energianvändningen för belysning i byggnader är viktigt för att uppnå målet att minska koldioxidutsläppen. Ett sätt att nå målet är om vi kan förändra människors beteende vilket kan ge en stor energibesparing. Feedback rörande energianvändning har ofta använts för att förändra beteende, men effektiviteten hos detta tillvägagångssätt är mer ifrågasatt för apThe lowering of energy use from artificial lighting in buildings is vital to reaching the goal of reducing CO2 emissions. Hence, changes in individuals’ behaviours regarding lighting use have received increased attention. Feedback on energy use has often been used to change individuals’ behaviour. However, it is not clear to what extent this approach can be applied for non-residential buildings, w
