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

Detailed report on five seminars held in Malmö and Leicester, exploring ways in which Christian, Muslim, and secular groups work together in multicultural contexts, using dialogue as a means of effective "striving/Jihad" against social discrimination and exclusion. Includes reflections by the Christian and Muslim authors
In a previous paper (Mårtensson 1988 a), results of tests performed on hardboard in tension under cyclic humidity were presented and comparison with a suggested constitutive model was made. This paper presents the result of further work that has been carried out concerning modelling of the behaviour of tempered hardboard subjected to moisture loading combined with mechanical loading. Tests were ma
A primary purpose of traditional systems analysis is seen as ‘capture’ or ‘elicitation’ of user requirements, in order to produce specifications as a basis for information systems design. Such a view presupposes that user requirements are pre-existing and clear, and that the particular ‘users’ concerned know what they are, and can therefore articulate them. We would argue that none of these assump
Popular Abstract in Swedish Ett flertal produkter som framställs inom den kemiska och biotekniska industrin produceras i stora turbinomrörda tankar. Kvaliteten av produkten och utbytet av processen påverkas av blandningsförhållandena i dessa tankar. Blandningsförhållandena i processen påverkas av vätskans hastighet och dess intensitet. I olika regioner av reaktorn, impeller regionen och bulk regiTurbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. Local turbulent flow parameters, the turbulent kinetic energy and the local energy dissipation rate,
