Outage time after extensive blackouts depends very much on the power system restoration process. Power system restoration is a very challenging task to the operator since the situation is so far from normal conditions. This paper proposes a simulation-based tool that determines a feasible sequence of operator actions that restores power system operation. The effect of each candidate switching oper
The amount of electrical loads and the complexity of the electric system in a vehicle is increasing at the same time as the allowed development time is getting shorter. Possibilities to predict the electromagnetic behaviour is therefore of great importance. In this paper, a method for determining the parasitic components affecting crosstalk in a cable harness is proposed. The method suggests that

Detailed quantitative characterization of the combustion gases from a series of room fires is reported in this article. Three simulated room fires were conducted with a test room containing a typical domestic fuel load of furniture including a TV-set. Two types of TV-sets were studied in the experiments, i.e. those containing fire retarded and non-fire retarded enclosure material. The measurement
Popular Abstract in Swedish För att styra, övervaka och utvärdera processer inom processindustrin, samlas stora mängder data från mätgivare i olika delar av processen. Den tekniska utvecklingen inom mätteknik- och datorområdet har gjort det möjligt att mäta många olika storheter. Inom processindustrin kan antalet vara mycket stort; hundratals och ibland tusentals värden loggas kontinuerligt med inIn this work, various aspects of multivariate monitoring and control of wastewater treatment operation are discussed. A number of important difficulties face operators and process engineers when handling online measurements from wastewater treatment processes. These include, for instance, a high number of correlated measurement variables, non-stationarities, nonlinearities and multiscale process b
Ring-Contraction of sugar-derived epoxy alcohols, functionalised in position 1 and 6, by treatment with lithium bromide and N, N, N', N'-tetramethylurea in refluxing toluene gave enantiomerically pure a,b-unsaturated aldehydes of furanosides. O-Glycosidic epoxy alcohols gave only one, easily purified, aldehyde in approximately 30-60% yield depending on the substitution pattern. C-Glycosidic epoxy
When the metabolic activity of bacteria is exploited by the food and biotechnology industries, freeze-drying is commonly used to produce concentrated bacterial cultures with enhanced storage stability. The freeze-drying tolerance of the probiotic strain Lactobacillus reuteri and the biocontrol agent Pseudomonas chlororaphis has been characterized in this work. Lb. reuteri was found to have higher
Abstract The project’s main objective is to verify the existence of local colours and colour schemes in the exteriors of buildings. The research focused on 19th century dwellings in the rural areas of southern Sweden. The results and furthermore the conclusions are presumed to reveal locally differentiated colours used and to indicate rules governing the way in which the colours were combined duri
EuroScreen is a project specifically designed to capitalise on the major economic and cultural opportunities presented through screen tourism. The three year project, co-financed by the European Regional Development Fund and made possible by the INTERREG IVC programme, aims to exploit the screen sector as a proven catalyst for tourism development through the alignment of policies between the scree
