Norconsult AB has developed a solarhousing concept, a house designed for the warm climate in the Middle East andwith large quantities of solar panels installed. The cooling system for the house was designed in an earlier report, the purpose of this thesis is to investigate the possibility of short and long term storage of thermal energy via an underground energy storage volume.Two different designs of the storage and three different filling materials have been integrated into a model to simulate different cases. The first design consisted of pipes installed in the ground, without insulation. The second design consisted of an insulated concrete box installed to prevent thermal energy from the surrounding soil to flow towards the lower temperature regions within the storage. The three different filling materials were dry saudi sand, water saturated saudi sand and the filling material used by the client for energy storage in Sweden.The results from the simulations show that neither of the designs, regardless of the filling material, managed to extract enough thermal energy from the house to the ground to uphold the demands of indoor climate.

Sedan ett antal år håller Försvarsmakten på att utveckla Försvarsmaktens Arkitektur och Försvarsmaktens Arkitekturramverk. Försvarsmaktens Arkitekturramverk skall vara ett stöd och styrning för Förvarsmaktens förändring och vidareutveckling, både nationellt och internationellt, samt spegla version 3 av NATO Architecture Framework. Ett försvarssystem vilket är utvecklat och används vid internationella insatser idag är Internationella Korvettstyrkan.Oförståelse för när, var och hur ett arkitekturramverk skall användas går att identifiera inom Försvarsmakten. Ett sätt, för att bringa förståelse för vad ett arkitekturramverk innebär, är att studera dess nytta. Denna uppsats har till syfte att visa på eventuell nytta med NATO Architecture Framework utifrån Internationella Korvettstyrkan.

This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.

The purpose of this study was to investigate the problems of building a new region in the Southeast part of Sweden. The idea of a big south Swedish region is brand new; no former studies in this area have been done before. The main analytical focus of this study is legitimacy, identity and democratic credentials. The study has been carried out by interviews with several leaders in organizations working with the collaborations of the smaller regions in to the big region. The method of this study has been a single-case study and dialogue interviews.

Thinning is the partial removal of trees in a forest stand prior to final harvest. The term can be divided in pre-commercial thinning where little if any volume is removed from the stand and commercial thinning where removals are intended to provide a positive economic result. From a silvicultural point of view, the goal of thinning is to enhance future crop tree quality by removing low-quality stems and providing sufficient space for the accelerated development of retained ones (Huuskonen & Hynynen, 2006). The goals of this study was to see if commercial thinning could positively affect the short and medium term timber supply (MTTS) in the Interior regions of British Columbia (BC), and whether or not Scandinavian forestry practices could be adopted in the BC context. The mountain pine beetle (Dendroctonus ponderosae Hopkins) has created significant forest planning problems in BC. The annual allowable cut (AAC) was raised to capture beetle-killed timber while still merchantable.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

With numerous applications in both military and civilian life, the demand for accurate 3D models of real world environments increases rapidly. Using an airborne laser scanner for the raw data acquisition and robust methods for data processing, the researchers at the Swedish Defence Research Agency (FOI) in Linköping hope to fully automate the modeling process.The work of this thesis has mainly been focused on three areas: ground estimation, image segmentation and classification. Procedures have in each of these areas been developed, leading to a new algorithm for ground estimation, a number of segmentation methods as well as a full comparison of various decision values for an object based classification. The ground estimation algorithm developed has yielded good results compared to the method based on active contours previously elaborated at FOI. The computational effort needed by the new method has been greatly reduced compared to the former, as performance, particularly in urban areas, has been improved.

The main purpose of this master thesis is to investigate the information seeking of lay politicians, part-time politicians and professional politicians in connection with the possible upcoming fusion of the two administrative regions, Västra Götaland and Värmland. The focus of this study has been to study how politicians use and evaluate information and sources of information, and to investigate if there are any differences in how different categories of politicians seek information. Seven politicians were interviewed using semi-structured questions, and a phenomenographic approach was used to analyze the data. In Sweden there are few available studies of how politician seek information, but some international studies have focused on information needs, information sources, selection and evaluation of information. I have used previous research, and data from respondents to compile and analyze my results in three descriptive categories.

This thesis deals with the concept of soft balancing, traditionally defined as the diplomatic means of restraining a dominant state's ability to exercise its military power. As the dominant power in today's unipolar system, the United States, and other states? behaviour towards it, is the focus of analysis. The aim of this thesis is to explore the possibilities of developing the concept of soft balancing so as to include strategies to restrain also the political and economic capabilities of a dominant power. The thesis also considers the possibilities of soft balancing that small states ? to a large extent overlooked in existing theories on the subject - can possess.As a state with policies that aim to reduce the U.S.

Örlogsfartygens utveckling går emot smygteknik, d.v.s. reducerade signaturer. Ett led i dettaär att spaningssensorer för luftspaning idag kan göras passiva. Smygfartyg utrustade medpassiv luftspaningssensor behöver en icke-röjande kommunikation mellan fartyg för att kunnaöverföra måldata, utan att den upptäcks s.k. ?tyst? kommunikation.Uppsatsen tar fram ett antal krav som ställs på den ?tysta? kommunikationen mellan korvetteri ett luftförsvar av ett skyddsföremål (ett annat fartyg).

The role of cultural policy within the general political planning of a community can vary both historically and regionally. The aim of this study has been to explore the cultural policy plans, during the 1990's, in the recently formed geographical region of "Västra Götaland". This is a qualitative study, carried out during 1999, and based upon structured interviews with five representatives of the cultural-policy sector in the "Västra Götaland" region. In order to identify connections and tendencies in a more general social context the aims of the five representatives regarding cultural policy have been explored from the perspective of three cultural policy paradigms, namely Dorte Skot-Hansen, Olav R. Spilling and Göran Nylöf.

Syftet med uppsatsen var att genom en socialpsykologisk undersökning studera hur soldater i Försvarsmakten upplever och hanterar konflikten mellan deras militära- och civila identitet.För studien intervjuades sex soldater som tjänstgör vid ett regemente i Sverige.Resultatet visade att flertalet av de intervjuade tyckes vara måna om att visa på en distansering från jobbet när de var lediga, och att de då ?återgick? till sin civila identitet, för att sen växla tillbaka när de var tillbaka i tjänsten. Emellanåt verkade det dock vara svårt för soldaterna att skilja de två åt och fler tycktes ?trilla? tillbaka till sin militära identitet, även i den civila vardagen. Det observerades därför ingen större konflikt mellan den militära och civila identiteten eftersom soldaterna tycktes välja en stabil identitet att använda sig av över tiden.  Hos flera av soldaterna fanns en ovilja att jämföras med de stereotypa ideal som allmänheten hade om dem och de valde därför att ta avstånd ifrån dem och definiera om situationen för de som hade den uppfattningen.

The aim of this report is to give a description of a diploma work of 20 points that has been performed during the spring 2006 at Ericsson AB in Borås. The report accounts for the problem and procedure during the diploma work. The software used for this project was embedded in a radio link. The RAM in this radio link was divided into several regions where two were used for memory allocation. The current allocation of memory in the radio link was not optimized with regards to performance, security and memory use and the configuration used made it difficult to determine the memory use of the system and the actual memory need.
