Att ta vara på solens fulla uppvärmningskapacitet
The purpose of this bachelor´s report is to expand the knowledge about heat supply of a small house in Malmö. The heat supply will be provided from solar panels in combination to two accumulator tanks which will storage the up heated water and a pellet boiler.The technique used here is warmth storage in water over seasons, which will provide the total need of heating for the house. Accumulator tanks in combination to solar panels gets more and more common in Sweden but this far it´s unusual to use it for storage over seasons. This report will highlight many of the difficulties associated whit heat storage and give information about a system's possible design and function.The design of this system is decided early on. An accumulator tank is placed 2 meters down in the earth on the backside of the house.
Drömmar : drömmen som inspiration och utgångspunkt för ett konstnärligt arbete
The theme of my exam project, the practical work and the essay will be the phenomena of dreams. The dreams you have when you are asleep, the dreaming state of mind, places where your mind takes you, when you no longer decide what to think of. It is a fascination about what our mind creates itself. This essay brings up the theme out from seeing the dreams and the unconsciousness as a source of inspiration, both in personal development and from an artistic point of view. How has the world of dreams bin used as inspiration in the art? .
Gott föräldraskap kräver kompetenta föräldrar : en studie om hur maktrelationer mellan föräldrar och samhälle framträder i en statlig text om föräldrastöd
Uppsatsen handlar om konsumenter som producerar produkter som sprids och konsumeras av andra konsumenter. Fenomenet kallas i denna uppsats för konsumentproduktion och jag har inte hittat bra litteratur om ämnet. Dagens allmänt citerade marknadsföringslitteratur som studerats i denna undersökning nämner inte konsumentproduktion som sprids till andra konsumenter. Den litteratur om Open Source som studerats nämner konsumentproduktion, men terminologin för konsumentproduktion är oklar och fokus sätts aldrig på ämnet. Litteraturen i motsats till denna uppsats nämner dessutom bara en mycket speciell och extremare variant av konsumentproduktion som produceras av högt kompetenta programmerare; istället för att som i denna uppsats ge bilden av att även andra konsumenter med andra eller ingen kompetens alls utför konsumentproduktion.
Konsolidering av v?vsp?nda papperstapeter: analys och metodutveckling
Printed and painted wallpaper on a weaved fabric backing was a common way to decorate homes in Sweden during the eighteenth and nineteenth centuries. Not much is written about the craftsmanship in relation to the hanging of these wallpapers and even less about the conservation of the objects. Even so, many wall segments remain in situ and in museums and are more often than not in dire need of conservation such as deacidification and consolidation. These are composite objects, consisting of cellulose materials with different properties along with adhesives and paints. Analysis of the materials is required to ensure safe handling and choice of conservation materials, and to establish a treatment plan which will be executed in several steps.
This thesis aims to identify these steps and develop a method for conserving the wall segments with suitable materials, preferably without altering the source material to any significant degree.
Nätverksövervakning av industriella miljöer : En lösning med öppen källkod
Denna uppsats undersöker möjligheten att använda ett nätverksövervakningssystem för att även övervaka maskindrivna processer. Kan man baka ihop övervakningen av den maskinella processen och datorn som styr maskinen i ett och samma system? Detta genomförs genom att identifiera och implementera ett lämpligt övervakningssystem i en befintlig maskinell laborationsmiljö. Arbetet utvärderas därefter enligt ett antal felscenarion och även utifrån ett systemadministratörsperspektiv. Intervjuer med praktiker inom industribranchen utförs också för att dra ytterligare slutsatser..
Norrkila arena : visuell beskrivning av arena
A home for elderly is planed to be built at Zakrisdal, Karlstad, Sweden. The heat source for the building was at the time not determined. In order by the local government of Karlstad this report is meant to examine if the need of heat could be provided only by solar heat combined with a seasonal heat storage. The problem to solve is, if the need of heat from the home for elderly is provided from only solar heat, whitch dimensions of the solar collectors and the storage is needed?.
Solenergi En del i ett långsiktigt, hållbart byggande
The sun is essential to life on earth and no matter where you are, there is a constant need ofenergy. Nearly 800 000 years ago man learned for the first time to use fire in a controlled way.Since then, fire has given us the opportunity to inhabit places despite a cold climate. In Swedenthe resident sector accounts for a major part of the total consumption of energy. In a time whenenvironmental issues and greenhouse effects are increasing, we also see a future of rising energyprices. With this perspective, we have in this bachelor thesis in the Building Environment at theRoyal Institute of Technology, KTH, in Stockholm decided to focus on the renewable energysource, solar energy.The energy from solar radiation is a free resource and does not have any negative effects uponthe environment.
Gräfsnäs dolda skatter
This paper examines how to use different kinds of source material for building surveys. The studyexamines how to use legends, construction archaeological surveys and Ground Penetrating Radar(GPR) as source material, and use them against each other to ensure the reliability they have.As a starting point I used Gräfsnäs castle ruin in Alingsås, Sweden, as an example. Gräfsnäs castlewas probably built in the Middle Ages and was rebuilt through the ages until it became a ruin in thelate 1800s. The castle ruin is today Alingsås most visited attraction.The investigation has focused on three areas which are located in the very ruin; rescue tunnels, thecellar vault and the treasure.There are legends that describe how the castle lord of Gräfsnäs fled an attack of the Danes in 1612 ina rescue tunnel which ended at the beach. At the construction archaeological surveys carried out in1935-36 they found a sewer in the courtyard that was once served as rescue tunnel and ended in themoat.

Värmeöverföring i bergvärmesystem : En numerisk analys av den ringformade koaxiala borrhålsvärmeväxlaren
The borehole heat exchangers of today suffer from poor thermal and hydrodynamic performance. The purpose of this thesis is to improve the performance of ground source heat pump systems and thermal energy storages by increasing the energy efficiency of the borehole heat exchangers. For this reason, the annular coaxial borehole heat exchanger (CBHE) has been analyzed. This type of heat exchanger is interesting in terms of both thermal and hydrodynamic performance. A model has been set up in the program Comsol Multiphysics in order to investigate the heat transfer characteristics along the borehole.
Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen
During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.
Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank
The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.
"I världen, men icke av världen" : Konstruktionen av kristen manlighet i Skånes Missionssällskap ca 1939-1945
The aim of this study is to analyze the construction of "Christian masculinity" during the modern era. This is made in opposition to earlier research that has claimed that masculinity could not be constructed religiously, that is, without at the same time being constructed as effeminate or anti-masculine.Using a wide variety of theoretical concepts - such as discourse analysis, class, secularisation, masculinity as constructed from countertypes, and finally masculinity as a homosocial construction - I analyze a free church in Sweden, the Scanian Missionary Society (Skånes Missionssällskap), during the period of ca 1939-1945 (the society was a district of the Swedish Covenant Church, or Svenska Missionsförbundet), in order to argue for the standpoint that masculinity, in fact, could be constructed religiously. The primary source is the society's weekly journal Sydposten.The main results in this study can be summarized as follows: 1) The leading men in the Scanian Missionary Society did, in fact, construct a Christian masculinity, i. e. a masculinity whose core values and ideals were Christian, e.g.
