Det energisnåla isoleringsmaterialet

This bachelor essay is divided into two parts, the first being a construction of a single-familyhouse and the second an in-depth study of five different isolation materials, analysed from anenergy perspective.The first part, the construction of the single-family house, has been created from knowledgeacquired during three years of studying at KTH Royal institute of Technology in Stockholm, inthe program Architecture and the Built Environment. The constructed house is a one-floorhouse of 137m2with façade plaster, situated in Borlänge, Sweden. The house has a wooden framewhich is built on a on sight cast concrete foundation, on the ground. The house?s roof is a gableroof, which has an angle of 24 degrees.

Solel från ljudbarriär : längs Annetorpsvägen i Hyllie, Malmö

City of Malmö has ambitions for the district Hyllie to become a demonstrative area ofsustainable urban development. As a part of this the following report aims to investigate the potential in using noise barriers combined with photovoltaics along Annetorpsvägen to generate solar electricity. To quantify the losses that shadows from buildings along the roadmight cause, a 3D-model of the area was constructed in SketchUp. This digital model made it possible to simulate shadows and how they change over the year. A reference model of a photovoltaic noise barrier (PVNB) was constructed and used to find the dates on which the solar cells are shadowed depending on building heights and positioning of the barrier.The results show that two lengths with a total distance of 400 meters is appropriate for applying photovoltaic noise barriers.

Elevers värderingar av föräldramedverkan i grundskolan. : En enkätundersökning

AbstractParental participation is something that is included in school either we like it or not. Several studies have been done about this phenomena but not many of them have examined the pupils estimation about parental participation. Therefore did we get interested about the pupils situation because why haven?t almost anyone asked the pupils about this phenomena when it?s constructed fore them? To learn more about the pupils estimation did we a questionnaire in twelve different classes with children in the ages between 10-16 years. The results we got from the questionnaire concerning the pupils estimation about parental participation were both expected and unexpected.Keywords: Parental participationQuestionnairePupil estimation.

VILKEN STRANDVEGETATION BIDRAR TILL DET ORGANISKA MATERIALET I KUSTN?RA SEDIMENT? Kols?nkor/k?llor, nedbrytbarhet och eDNA sp?rning

Coastal sediments are important carbon sinks, storing organic matter and thereby helping to reduce the amount of greenhouse gases in the atmosphere. However, they can also act as carbon sources if the deposited organic matter decomposes rapidly, contributing to increased greenhouse gas emissions and global warming. Rapid decomposition partly depends on the degradability of the material itself. In this literature review, I examine which coastal plant species dominate different locations along the Swedish coast, based on coverage data from the ClimScape project (www.climscape.se). For the most dominant species, I investigated the type of organic matter they may contribute to the sediments and based on those results I qualitatively assessed which sites that may function as carbon sinks or sources.

Idén var det inget fel på : En processutvärdering av omfördelningen av befintliga arbetsuppgifter på ett frivårdskontor

The essay discusses a process of change at probationservice office. The purpose of the change was to decrease specialisation and increase flexibility of the probation officers. The change encountered several problems where the correctional supervisor was percieved to act unsurely and indecisively whilst parts of the staff constructed and implimented several courses of action to prevent the process of change..

Prestations- och kvalitetsstudie av maskiner för rensning av skogsdiken

Ditch cleaning is increasingly important in Swedish forestry. This study compare different concepts concerning machinery, namely two general-purpose excavators of different sizes, 8 tonnes and 15 tonnes, versus a dedicated machine constructed solely to deal with ditch-cleaning. The machines were tested on rough as well as on gentle terrain and on open terrain as well as in young stands in connection with thinning. The conclusions were that the excavators are more versatile and have greater capacity than the dedicated machine, while the latter excels in quality of work. Interestingly, there was no significant difference in performance between the both excavators..

Undersökning av energibesparande metoder för multiplikator

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

Det kulturella tomrummet : En diskursanalys av kulturprojekt bland elever på särskilda ungdomshem

This essay deals with the rationale and aims for doing cultural or aesthetic activities and projects in schools, and gives special focus to a specific group of students, attending schools provided at special residential homes for young people (sa?rskilda ungdomshem). These homes receive young people with psychosocial and substance misuse problems and who show tendencies towards criminal behavior. The essay investigates how working with a cultural project in schools at these residential homes is justified and also elucidates how this specific group of students and their problems are constructed in the documents surrounding the project. The essay will further ponder over possible educational and pedagogical consequences of these constructions.The investigation has its theoretical frame work in curriculum theory.

Laserprojektor

This report describes a thesis project on 15hp. The purpose of the thesis project is to build a laser projector that reacts on sound waves and thus get a laser beam to draw visualizations of sound waves on a wall. The idea was that the design would be independent and not have to be plugged into any audio equipment. This was achieved by absorbing sound waves into a microphone. Another factor was to get a ?do it yourself? -feeling of the design and therefore it was chosen to be constructed using for example, old hard-drives.The result was a relatively large and bulky designed laser projector that can draw sound waves on a wall..

Viking center

My diploma thesis has focused on creating a proposal for a Viking center in Stockholm that meets the international interest. A building dedicated solely to the Viking heritage. My ambition has been to give the Viking center an architecture that can serve as scenography for its exhibitions and to give the visitors a feel for the Vikings that they have been craving.  A boat-shaped building in tribute to the Vikings boat building skills with curved stems of equal height that gives a familiar silhouette to the city.  A wood building constructed of curved beams and wood columns painted with tar..

Beräkning av ASME-flänsar enligt EN-standard

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

"Jag tror att det är ärftligt och att det är biologiskt.. och så tror jag att det är.. eller ja.. jag tror att det är biologiskt". Konstruktionen av ADHD och DAMP i skolans och vetenskapens värld

The purpose of this study was to investigate the understanding of the diagnoses ADHD and DAMP within different professional categories in the educational system, how it is being addressed and how this affect their work with children diagnosed with ADHD or DAMP. We also wanted to shed some light on the debate between Kärfve and Gillberg, about whether the diagnoses of ADHD and DAMP are social constructed problems or biological and genetic disorders. More specifically, our study was of a qualitative nature and consisted of interviews with seven persons working in six different professions within the educational system. The respondents all worked in school environments but with varied roles and thus varied experience of children with ADHD/DAMP. The interviews and literature studies revealed the complexity of ADHD and DAMP and also the diversity of the debate regarding the diagnoses.

Kommunala webbplatser för alla eller några? : Kvalitativa intervjuer med webbansvariga i tio sydsvenska kommuner

There is a need for examining the accessibility of public web sites and for several reasons. First, public organizations possess considerable amounts information of interest to its citizens and which ought to be easily accessible. Secondly, international and national guidelines for web publishing support the different types of requirements experienced by web users and, in particular, with regard to accessibility for people with disabilities. The thesis examines the design of public web sites from two different aspects. Web sites can be built up and structured from the management view of the public organization, or, they can be constructed with a view to user needs and requirements.
