Exterior Colours at Rural Dwellings in Southern Sweden during the 19th Century - To increase knowledge regarding local differentiations

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

Start-up Optimization of a Combined Cycle Power Plant

In the electricity market of today, with increasing demand for electricity production on short notice, the combined cycle power plant stands high regarding fast start-ups and efficiency. In this paper it has been shown how the dynamic start-up procedure of a combined cycle power plant can be optimized using JModelica. org, proposing a way to minimize the start-up time while maximizing the power pr

The meaning of meaning in biology and cognitive science. A semiotic reconstruction.

Abstract. The essay aims at integration of different concepts of meaning developed in semiotics, biology, and cognitive science, in a way that permits the formulation of issues involving evolution and development. The concept of sign in semiotics, just like the notion of representation in cognitive science, have either been used so broadly as to become almost meaningless, or they have been outrigh

A Chemometric Approach to Process Monitoring and Control - With Applications to Wastewater Treatment Operation

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

I historiens ljus

This chapter deals with Drottningholm Palace during the 19th century and examines issues concerning architecture and interiors.

Towards a Green Energy Economy?

The global financial crisis provided an opportunity for countries to reduce their dependence on fossil fuels. Green energy technologies were heavily promoted as a way to reinvigorate economies, create jobs and reduce CO2 emissions. However, despite multiple policy efforts, data show that emissions continue to rise. The limited progress made in many parts of the world has been insufficient to offse
