Energy efficiency is today more important than ever, mainly due to the high energy prices and the approaching climate changes. Heating of buildings is an essential area within energy efficiency. Many buildings are old and were built at a time when the energy prices were low and the term ?energy efficiency? was unheard of. By applying today?s broad range of energy saving actions on these old, and thereby often, heating ineffective buildings, this area has a large potential in reducing energy consumption and costs.Churches and chapels are generally old buildings with, in many cases, ineffective heating systems and therefore consume much more energy than needed.

ABSTRACTThe discussions about energy use have increased year by year everywhere in the society, and so also in the healthcare sector. But what is actually energy use in a hospital facility, and what affects it?The typical way today to express the energy use is in kWh/m2. The problem with a key performance indicator that is expressed as energy use in relation to a specific area is that it does not take into account the activity in the building. Even though the activity to a very high extent affects the energy use.

In today's society, the availability of energy plays an integral part in our everyday lives. Unfortunately, the price of energy in Sweden has increased in recent decades. A large part of our energy consumption goes to heating modules for houses, where heating methods that depend on energy sources such as electricity, district heating, fuel oil, gas and biofuels are the most common ones. During the winter period, the increase in energy costs becomes significantly evident, especially for small property owners. This increase in energy cost is most noticeable for home owners with electric heating.This thesis is written at the Halmstad University, in cooperation with a company, which makes parts of this thesis confidential.

There is always a need for more effective ways to store energy in order to reduce the human impact on the environment. One step on the way can be the use of flywheels as kinetic energy storage devices. Low frictional losses are essential for a flywheel to be effective. To minimize these losses active magnetic bearings (AMB) can be used to keep the shaft centered instead of the more conventional ball-bearings. AMBs use actuators and a fast control system that needs correct and noise-free measurement data of the shaft position and the current in the actuators to work properly.This thesis explains the process of constructing power electronics and a current measurement system for active magnetic bearings (AMB).

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

This thesis deals with different methods for measuring moisture-related dimensional changes ofwood. Typically relative humidity is measured to determine if the ambient climate around anobject is harmful to it or not. Values between 40 to 65% RH are recommended for hygroscopicmaterials. To know how a wooden object actually reacts to changes in the surroundingenvironment requires methods that involve the object itself. Because of the wood anisotropy,differences in wood structure, finishes and other restraints, it is not always possible to predict themovements.This paper addresses various measurement methods, primarily methods that have been testedin the field of conservation, with examples of their use.

WesDyne TRC AB is a fully owned subsidiary of the global WestinghouseElectric Corporation. WesDyne is a world leader in non-invasive methods for theinspection of nuclear power plants. One of the inspection platforms used to scanfor defects in and around the welds in the reactor vessel is called the T-crawler.The T-crawler operates under water in a radioactive environment by stepping onthe vessel (reactor tank) inner wall using suction cups. The environment is harshand many traditional positioning sensors are not suitable for implementation. Thisthesis investigates the possibility to use a gyroscope and a pressure sensor tocreate an alternative and independent positioning system.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

The main ambition 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 tariff regulation. Interviews have been conducted with specific network companies and Energimarknadsinspektionen. The proposed regulation of 2012 is discussed from the government?s proposition.This paper clearly shows that the authority´s work has been conducted in a very unprofessional manner during the period of The Network Tariff Model.

Denna studie syftar till att kartlägga vilka organisationskulturella framgångsfaktorer som finns representerade i Gores organisationskultur samt om det finns ett samband mellan dessa faktorer och ledarskapet på Gore.

This thesis is a product development project that was performed at Alfa Laval Tumba AB. In the past Alfa Laval have manufactured gas separators for engines where gas flows were cleaned from oil. A new business area for this kind of technology has shown to be the manufacturing industry where oil mist has to be separated from the vented air. Therefore a new and bigger design is needed to be able to handle the greater gas flows. A product like that would be a strong competitor on the market when the maintenance would be low in comparison to today?s equipment.During the project several concept suggestions were developed using customer interviews and research as input.
