… in the farm operation. The aim with the biogas plant is to produce non fossil electrical and gas heat for own customs, to reduce smell impact from stables and to make possible different types of research investments within the area.This study has implemented multiple cases study …
hur stora är förlusterna?
… crop is grown on the farm and how the farmers protect themselves. On one farm electric fences are used with a good result, while one other said that it has no effect. Instead he argues that the only method that works is hunting, and that keeps the wild boars away from the field …
… (CE). CE separates protein due to their physiochemical properties by an electric gradient making proteins migrate through a capillary in different velocities depending on their respective charge in a determined pH. Protein quantification was obtained by comparing …
… A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different …
… information about the situation. At the Department of Computer Science and Electrical Engineering of the university, there is an ongoing project which aims to provide the ability of medical examination at distance by employing haptic robots. This thesis describes the process of …
Tidigare meningsskiljaktigheter samt undersökning av förutsättningar för framtida reglering
… of this degree project is to illustrate the fundamental problems of today’s electric tariff regulation and the usage of the analyzing tool; The Network Tariff Model. There is a further discussion of potential problems and clear improvements of the 2012 years proposed network …

… be slightly more profitable. In the calculations it was considered that an electric boiler would back up the heat pumps during cold days. With heat pumps, the energy bought for heating and hot water would be about 55 kWh/m2year, which is well below the goal of maximum 118 …
Bestämning av verkningsgrad
… usage of support energy in the biogas process is essentially district heating, electricity and oil. Theoverall efficiency term is the energy produced in the gas minus the supporting energy divided with theenergy from possible biogas production of the substrates. For calculation …
<em>Hur påverkas hyresgästerna av </em><em> en ombyggnad </em>
… of the tenants are dust, noise and difficult accessibility. Temporary electricity, water and ventilation failure are other types of disturbances that often occur at a reconstruction project. In this thesis, most of the disturbances are identified and also some approaches to …
… to a jack which is then placed inside the buoy. The jack is then powered by an electric engine. The report discuss what forces the buoy will be exposed to and then the structural integrity of the design is evaluated through simulations. Finnaly we look into the possibility of …
… PD, are a physical phenomenon in which discharges occur locally due to large electric fields. PD can occur in or adjacent to the insulation of stator windings and causes breakdown of the insulating materials. PD measurement can provide an idea of how widespread the PD activity …

… members and sponsors provided their time and knowledge in form of carpenters, electricians, plumber, painters and various hobby-carpenters. To plan and push through this project has not been easy with many different individuals involved. One important part has been to elect one …
… improvement. A new type of frequency control will be introduced onthe Nordic electricity market with the purpose of relieving the primary control. It willserve as a link between today's primary control and secondary control.
… the industry is used through an Organic Rankine Cycle (ORC)?process to produce electricity. An ORC-process is a thermodynamic circle process in which a refrigerant is used as the working fluid. The refrigerant makes it possible for the circle process to operate at lower …
