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.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.

This graduation paper is based on my interest for wood and its different tonal quality?s.After some time of thinking I decided to write my paper on the tonal difference between two of the most common woods in guitars, East Indian Rosewood and European Maple. I had built two identical guitars before my graduation paper in which the difference was the wood the back and sides were made of. One was being made of East Indian Rosewood and the other being made of European Maple.I chose to speak with a number of people with different angle of approach to the two kinds of wood and its tonal difference and quality?s.

This survey was made to investigate the possibility of using an alternative method of fencing inSwedish forestry. The most common way of fencing in Sweden today is made by a two meter highmetal net that is attached to turned impregnated poles. The fencing methods that have beeninvestigated is a fencing system made completely out of wood so called ?German wood fence?.Browsing of game in forest regeneration areas is often a big problem and some kind of protection ofthe plants is often necessary. There is several ways of building fences and the most common way isto use metal nets and impregnated poles, this leads to a problem when the fence has profiled itspurpose.

The responsibility to identify, protect, look after and develop cultural and historical values in our surroundings - urban as well as rural - falls on the local authorities. This essay focus on local preserve programs for cultural landscapes in Sweden?s municipalities. Programs for preserving cultural landscapes are important tools in the aim to reach a sustainable development of these values. The object of the essay is to delineate how the municipalities handle cultural landscapes in terms of how cultural and historical values is identified, how the landscape is divided and assessed and how different aspects of intangible and tangible values are taken into consideration.

As a guitarbuilder it is an advantage if you can control and understand what is creating the character of the tone. To approach this vast jungle of variables that controls the tone in a guitar, I built two guitars and in one, guitar 2, reduced the thickness of soundboard, back and sides.The purpose was to compare the guitars and establish if there was a significant difference and what it was, in the guitars ability to produce sound. The thought was also to try the thesis: loud but short, long but moderate tone. Also if a lighter built guitar has an advantage in producing a loud but short ton and vice versa.The instruments has been examined by five guitarist, one guitarbuilder and a professor in Speech, music and hearing at KTH in Stockholm.The relative obvious conclusion is that guitar 2 is a bit louder and has a clearer base and treble but the more part of the guitarists fancied guitar 1 better. This one has got more mass fore the tone to stay alive with.

In this thesis I have criticized traditional nationalism theories formulated by Eric Hobsbawm, Ernest Gellner, Benedict Anderson and Anthony D. Smith. The critique has been based on my belief that nationalism theories do not explain nations whose foundation is built on forward-looking, dynamic aspects such as economy, human and civil rights, and democracy. Traditional nationalism theories have been focused on historicizing perspectives whereas I want to draw attention to non-historicizing perspectives within the field of research. So far nationalism theories has had a shared past or a shared ethnicity as its focal point.

?Historiska Bakverk? is a project about different pastries from a historiacal perspective.The goal was to create illustrations and typography inspired by differentpastries, in order to communicate something about their history and what layunderneath. The project aimed to highlight, understand and acknowlage thepastries as an important part of our history and cultural heritage. Importantquestions I have dealt with throughout the project was in what way the pastriestell us about our history, how it has changed them through time. The result, aseries of posters for croissant, doughnut and pretzel, are a combination of boththeir history and my own experience of them.

After been told that an ordinary winter service for our combine should cost more than 20000 SEK, not included spare parts, I decided to write this paper about today?s requirement of the workshop on a farm. I think that the lack of proper premises is the reason way not more of the ordinary machinery maintenance or upkeep is performed on the farm. When I did my literature survey I found that the Swedish environmental code, set by the Swedish law regulate how drain or sewer should be built. The environmental code however leaves a lot for your own interpretation. It might not be so bad but it must be very hard for the local environmental office to interpretation the regulations, since they are the ones that gives permission for the sewer in your workshop.

This thesis deals with our heritage and the care of old buildings. In order to limit this vast area a specific attention has been brought upon the process of giving buildings a certain level of protection and after decision having it taken away, instead of giving a stronger protection level.Further limitation has been done through the choice of four buildings in Lund, within Lund University campus. These buildings all lost this certain level of protection. The participants in these kinds of cases have a level of power, what argumentation did they use?The methods being used are discourse analysis, phenomenology and the daily methods of the building care field..

Results have shown that flow batteries may be a solution in the future as an effective and environmental friendly method to an energy storage system (ESS). The technology is reliable and has a high efficiency that comes with low energy losses and a long lifetime. The range of possible fields is suitable for cutting energy peaks in the power grid, by always have a ready and available energy storage that balances the production. By comparing the advantages of flow batteries with conventional batteries it is mainly the fact that they can conserve energy for a long time without being self-discharged thanks to that the storage capacity is in principle endless and limited by the size of the electrolytes tanks that makes them a great energy storage system. The batteries won?t take any damage or decrease in performance when charging or discharging it or if you exhausts it to 100 % and leave it discharged for a long time.
