Micro-power wind energy convertors have recently increased in popularity. The reasons for this are among other things the increasing cost of electric energy and enviromental concern. In this thesis the connection of these micro-power wind energy convertors to the utility network …
… has permeated through the rendering in leaking connections and fittings for windows, doors, canopies, balconies, terraces and awnings. Behind the plaster carrier, which consists of either polystyrene or rigid mineral wool, plasterboard has often been used as a wind protection …
… that hinge planting offers an environment where seedlings are protected from wind, frost heaving and erosion while they at the same time are offered an adequate water and nutrient supply. Choice of planting spot was found to be crucial after mounding. A low planting position …
… is dependent on a well working video link, good base-height ratio and calm wind conditions.
… data for precipitation, temperature, solar radiation,relative humidity and wind speed, which enables long-term simulations of water andnitrogen flows. Three different simulations were performed, one for present climate as areference scenario with climate data from 1971-2000, and …

Detaljerad information om vindförhållandena på en site är en nödvändighet för att göra beräkningar av lönsamhet i ett vindkraftsprojekt. Mätningarna behöver vara kontinuerliga och så korrekta som möjligt. Därtill bör de göras under minst ett års tid eftersom vindförhållandena på …
… conditions such as high or low ambient temperature, heavy rain or strong winds. In this study, the daytime shelter-seeking behaviour of three groups of horses housed outdoors was studied during the summer. The aim was to evaluate whether shelter use is related to weather …
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which …
