Energiberäkningar för passivhus
AbstractClimate and environmental issues are of paramount importance. Researchers agreethat we must all contribute to a reduction of gases that contribute to climatechange. Energy consumption must decrease within all sectors and the promotionof renewable sources of energy must be introduced.Each sector should aspire to decrease its energy consumption. Energyconsumption is strongly linked to waste gases that contribute to climate change.Passive houses are a part of the construction industry's methods to attain energyconservation.Passive houses are derived from low energy houses and super insulated houses. Apassive house is intended to obtain heat from the inhabitants and through theiractivities.
Produktkoncept: lekhjälm i vintermiljö : ett nytt produktsortiment
A protection helmet for young people (3-7 years) in winter environment has been developed in this thesis. The result is a concept proposal for development at STIGA Sports AB in Eskilstuna. This thesis work has been performed during 20 weeks, for a Master of Science in Product and Process development at Mälardalen University Eskilstuna Sweden in September 2009 to January 2010. The helmet is shown as a CAD model with detailed solutions to the outer shell, interior and adjustability (in sizes 50-56 cm) which are the three focused areas in the development. Also a physical model in scale 1:1 has been developed and is shown in this thesis work.To achieve the best result possible the process started with an analysis of the market and the product.
Jakten på legitimitet, trovärdighet och det svarta guldet- Hur använder sig olje-och gasbolag av CSR för att erhålla " The licence to operate in Arktis"
Should libraries first and foremost be a source of free informationwhere the citizens can find whatever information they want, or dothe librarians have a responsibility for what kind of works theypresent to people on their shelves? A wild debate broke out inSwedish media in September 2012, after the artistic leader ofKulturhuset in Stockholm; Behrang Miri decided to weed out allthe Tintin albums from the children´s library Tiotretton. Hewanted to start a debate on stereotypes in children´s fiction, andwhat damage they do to children who face them. The purpose ofthe thesis is to carry out a discourse analysis of this media debate,and to identify the different views that are expressed on thedemocratic mission of the libraries, what media they shouldpresent. The method and theory is based on the discourse theory ofErnesto Laclau and Chantal Mouffe and their concepts are used toarrange the analysis around certain themes that build up twodifferent discourses; ?Freedom of information discourse? and the?Weeding out discourse?.The two main questions are: What views of the public librariesselection of works are expressed in the Tintin debate in Tiotretton,and how do the views relate to each other? What concepts arespecific for the debate, and what meanings do they get in thesedifferent views?In the concluding chapter I discuss which consequences theseopposing opinions can have for the future selection processes ofthe library..
Design och konstruktion av kaross till ögonstyrt arkadspel
Tobii Technology AB is a global leading company in eye tracking. The technology is a part of acomputer screen called an eye tracker. It enables computers to follow eye movement whichfurther make it possible to control the computer by only using your eyes.The mission was to develop an arcade game for eye controlled games that Tobii can use in theirmarketing or as a tool when doing researches about the interest in the technology amongst gamecompanies. The product realization involved designing an innovative, functional and futuristiccase which gathered the existing hardware and software to build the final prototype. In order toattract users it was important to focus on the visual expressions.Initially, the project started off with an information retrieval which contained interviews, fieldstudies, tests and literature studies.
Kiselalgernas missbildningar under toxiska förhållanden
A research of 14 toxic affected study sites in Sweden showed a significant increased proportion of deformed diatoms.
The six metal polluted study sites in the region of Dalarna showed a 4, 2% average of deformed Fragilaria (deformed diatoms reference sites, 0, 1%).
The results also indicate a significant increased proportions of deformed diatoms in the eight pesticide polluted sites in the south and middle of Sweden, compared to the reference sites, howsoever the toxic content was low.
The results indicate that there are no lager differences in neither teratological forms nor variations that segregate metal polluted and pesticide polluted shells. One of the reasons may be that both heavy metals and pesticides can affect the development of the diatom shell..
Passivhus ur en brukares perspektiv
Ett passivhus är ett hus som i stort sett enbart värms upp av människorna och elapparaterna som finns i huset. Särskilda krav för att få kalla huset för passivhus måste uppfyllas.Vi har gjort en enkätundersökning på tre olika passivhusprojekt för att utreda vad de boende tycker om inomhusklimatet. De utvalda projekten finns i Värnamo, Frillesås och Glumslöv. Enkätsvaren visar att de boende i Frillesås är mycket nöjda, medan mer än 50 % av dem som bor i Glumslöv tycker att det är för varmt på sommaren och för kallt på vintern. För att utreda om de olika konstruktionerna har någon inverkan på inomhusklimatet har beräkningar och simuleringar i datorprogrammen VIP+ och IDA gjorts.
Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud
The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.
Utveckling av Mätmetoder för Färdmotstånd
The student project Elba at KTH started in 2011 and is a project where a battery driven prototype car is developed. The vehicle competes in Eco Shell Marathon in Rotterdam, Holland. In this competition the vehicle that travels a certain distance including several starts and stops with the lowest energy consumption wins. To minimize the consumption is therefore very important, which requires knowledge of the vehicles energy losses.A vehicle's energy losses depends on several factors and can be divided into the powertrain efficiency and the driving resistance. The driving resistance can then be divided in to rolling and air resistance, if smaller losses like vibrations are ignored.
Från ståtlig befästning till vittrande världsarv : En jämförelse av byggnadstekniska metoder för sammanbindning av skalmurar
This is a final year project considering constructional techniques for joining cavity walls. The project is related to an ongoing scientific programme about the restoration of The City wall of Visby located on Gotland. The programme was set by Riksantikvarieämbetet as a reaction to a collapse of the outer masonry wall shell which took place in February 2012.The City wall of Visby is a medieval fortification built out of limestone during the 13th century. The wall is constructed as a cavity wall with two separate masonry shells connected to each other through an intermediate core. During the 14th century the wall was heightened which lead to a higher stress, especially in the outer wall face.
Nollenergihus i Borlänge : Är det möjligt med biomassa, solenergi och vindkraft?
This report is of technical character and treats how to plan a small building in Borlänge, Sweden.The technical components that have been treated in the report are the construction, foundation,installations and thermic abilities of the house. In addition to planning this house the report alsocontains a part that deepens in net zero energy buildings. The purpose of the report is toinvestigate if the house in Borlänge can be constructed to meet net zero energy buildingdemands.Energy efficient houses such as passive- and net zero energy houses are showing more frequenton the market in Sweden. Ongoing climate changes and growing consciousness about theenvironment in society have contributed to that the environment is a well discussed topic. Toconsume small amounts of energy and at the same time produce local energy is thereforesomething that lies in the future and future houses.
Den villkorliga självkänslans relation till self-efficacy
A self-esteem that is contingent on affirmation from others leaves the individual psychologically vulnerable. Ccontingent self-esteem has been shown to be either relationship or competence based. The aim of the current study was to examine the relationship between relationship based self-esteem, competence based self-esteem, the under dimensions of those, and self-efficacy. Questionnaires were handed out to 69 university students. The results indicated that competence based self-esteem predicted a significantly low self-efficacy.
LEED i Sverige och i byggprojektet Borgarfjord 3.
This thesis provides a good introduction to the American environmental certification system LEED, Leadership in Energy and Environmental Design, and trough compar-isons between Sweden and the United States an explanation to the systems design is given. The work is closely linked to a LEED Core & Shell project in Stockholm, Swe-den, where the goal is to reach the second highest rating in LEED - Gold.This thesis gives a broad description of the LEED system and a more profound study of the energy sector, Energy and Atmosphere. Here, for example, an analysis has been made of how the energy consumption of an imaginary building designed according to the requirements of the BBR (Swedish building code) performs in comparison to the Baseline building in LEED.The existing model of Borgarfjord 3, which served as a case study in this work, has al-so been modified to investigate the energy savings that could have been achieved by adding extra insulation to the building. A description of the problems, regarding how the Swedish district heating system (DES) is treated in LEED, is given as well as the suggested modifications. This is an issue that will be pursued during the process of shaping a new, international, version of LEED due to be launched 2012..
Nyutveckling av Nålträdarsystem
This thesis work is performed on VSM Group Ltd in Huskvarna that produces sewing machines under the trademarks Pfaff and Husqvarna Viking. On these sewing machines is an application that helps the user to thread the needle. The aim with the work has been to study today's applications on VSM and their competitors' sewing machines in order to since developing a new Needle-threader that divides itself from all the ones used today. The objective with the work has been an entire new concept with an operational prototype.As a base the competitor analysis was used where today's applications was studied in order to identify positive and negative aspects of these. This led to a number off ?concept families? where different variants off the same ideas were collected and evaluated.
