… and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%. But in the end it was discovered that the circuit was only able to deliver 70A when the thought was 200 A. More over …
Today produces the wind power 2,5 TWh (TWh = terawatt hours) of Sweden’s total energy input of around 620 TWh. The Parliament has adopted a national planning objective where the wind-based electricity production will increase to 30 TWh in 2020. This requires that landowners will …
Med fokus på Kvarteret Trettondagen
… heating mix ? 0,79 District heating from waste ? 0,04 Electricity from wind power ? 0,05 The results show that the passive houses in Trettondagen and Oxtorget were the only ones that passed the German limit of 120 kWh/m2Atemp,year. The low energy usage in Trettondagen could be …
… the rapidly growing energyprices. 1. Is it possible to design a micro scale powerplant? 2. Is it economically interesting for a potential customer to by such a product? The aim with this report is therefor, with the help of design work and calculations, to answer these questions …
… for control. Furthermore, the unequal distribution of resources results in a power asymmetry, hence the incentive to conceal deficiencies is difficult to eliminate and therefore a perceived need for control is reflected in the requirements. For the administrators this results in …
… converting the thermal energy of a combustion engine to mechanical/electric power the efficiency of the combustion engine can be increased. In this work the performance of a truck engine has been investigated with the aim to increase its efficiency by decreasing the heat losses …
… to other types of heating, their electricity use has decreased and the total power output from many of the secondary substations has decreased significantly. Because of this, many of these stations today are well oversized, which in turn means that the energy losses in these …

<em>En kvantitativ studie av bilder och skribenter på Aftonbladets viktsajt ur ett genusperspektiv </em><em></em>
… women and men. As for the viewing perspectives, our study shows that the power relationship between the depicted and the viewer often is equal for both women and men. The power relationship is however more equal for women than for men, the power relationship for the men is more …
Jämförelse mellan tre utvecklade versioner av ett vattenvärmedrivet torkskåp
… increasing problem caused by the high share of electricity produced in coal power plants. These contribute to high carbon emissions when only about 1/3 of the heat generate electricity and the remaining 2/3 of the heat cools off. Combined heat and power plants (CHP) have high …
… their daily life andhow these experiences may contribute to the awareness of power in professional relations.The study is based on three semi-structured narrative interviews and the main result showedthat, according to my interpretation, ECT as a treatment obliterated memories …
… using oil as a fuel many companies are looking to new and innovative ways to power their aircraft. One of these new ways to power an aircraft is using fuel cells powered using hydrogen and oxygen, thus producing nothing but water vapour and small amounts of nitrogen dioxide as …
