Hållbar design för en bättre värld -med hemlösa i fokus

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

Förståelse för visualiserad elförbrukning i publik miljö : En användbarhetsstudie av touchdisplayen Urban Energy

Hur publika displayer skall utformas och anpassas efter sin miljö på bästa sätt är ännu ett outforskat område. I takt med att miljöfrågor blivit än mer aktuella i dagens samhälle har det också etablerats ett behov av att förändra vårt beteende exempelvis i form av energieffektivisering. Syftet med denna uppsats är att undersöka hur en publik touchdisplay för elvisualisering skall utformas för att vara förståelig, intuitiv och säker från publik genans. En användarstudie i form av en utvärdering av en interaktiv touchdisplay kallad Urban Energy monterad i Göteborg har gjorts under ledning av Interactive Institute Swedish ICT. Touchdisplayens primära syfte är att uppmärksamma förbipasserande på stadens elförbrukning och uppmuntra till energimedvetenhet.I denna studie rekryterades 17 förbipasserande deltagare villiga att testa denna display med hjälp av två uppgifter och en enkät.

Arbetsrationalisering genom samarbete : en fallstudie

To be a part of the future we have to make a profit, one way to improve the profit margin is by reducing the fixed costs. This paper discusses the financial results of equipment cooperatives in crop production. Through a case study of three farms in Södermanland, we have an example of how it can look today and how it could look tomorrow. The three farms are crop-producing farms with slightly different orientation. Jursta Gård, 155 hectares, and Djursnäs Säteri, 215 hectares, have grains crop and oilseed crops as the main crops, and Nibble Gård, 340 hectares, mostly have pasturelands and some grain crops.

Användande av diffusionsspärr vid tilläggsisolering av äldre byggnader med trästomme

In the current situation a big part ofthe settlements that exist in Sweden isin need of renovation and energyefficiency in order to survive.Therefore, also many of the older houseswith a wooden structure are in a need ofenergy efficiency, which can be done ina variety of ways, including addinginsulation.This project deals with whether the useof a diffusion barrier or a vaporbarrier affects a wall structure byadding insulation to an older house witha timber frame. The insulation materialswhich are concidered in thisinvestigation are mineral wool and woodfiber insulation. Efforts are focused onthe effects of moisture on theseinsulation materials.To demonstrate the differences thatarise the moisture measurement programWUFI have been used to simulate avariety of wall designs. These designsare developed in consultation with theconstruction carers who are active inthe industry.Using WUFI graphs illustrating themoisture levels of the wall structureswere obtained and from these conclusionsvould be drawn. The work demonstratesthe differences that arise when using adiffusion barrier or vapor barrier inwall construction.

Utveckling av hygienfunktioner i diskmaskiner : Desinfektion med ånga

This report is the result of a thesis work in Integrated Product Development, regarding hygienic features in dishwashers and especially disinfection by the use of steam.The thesis is performed at Electrolux Primary Development Dishcare in Stockholm and in collaboration with the Department of Machine Design at the Royal Institute of Technology.The targets of the thesis are to prove the advantages of a technology suitable to implement as a hygienic feature inside a dishwasher and to realize a functional prototype of a differentiated hygienic feature that does not exist on the market today.The process followed to perform the thesis is the process defined for Electrolux Primary Development.The technology chosen for development is disinfection by heating the water on the surface of the dishware, by the use of steam.A number of tests on how steam behaves when injected into the dishwasher tub have been performed, providing the results that have been taken in consideration when designing the prototype.The prototype consists of a pipe system provided with nozzles to eject the steam into the upper parts of the dishwasher. Tests of the final prototype show that thermal disinfection of water in a dedicated area of the tub can be reached within 9 minutes. The operation requires 0,17 liters of water and consumes 0.2kWh..

 Traditionella metoder eller en dansande rosa panter? : En jämförelse mellan traditionella marknadsföringsmetoder och gerillamarknadsföring

Every day consumers are bombarded with different marketing messages from all possible directions. At the same time consumers starts to actively and consciously avoid these messages. Therefore, marketers have to start thinking outside the box and find new ways to get consumers' attention. One of these methods is called guerilla marketing. The strength of guerilla marketing is its way to be unexpected and unusual.

DistroFS: En lösning för distribuerad lagring av filer

Nuvarande implementationer av distribuerade hashtabeller (DHT) har en begränsad storlek för data som kan lagras, som t.ex. OpenDHTs datastorleks gräns på 1kByte. Är det möjligt att lagra filer större än 1kByte med DHT-tekniken? Finns det någon lösning för att skydda de data som lagrats utan att försämra prestandan? Vår lösning var att utveckla en klient- och servermjukvara. Mjukvaran använder sig av DHT tekniken för att dela upp filer och distribuera delarna över ett serverkluster.

Emotioner och emotionella uttryck i Sverige och Grekland

The purpose is to explore and describe norms and values concerning emotions and emotional expression inSweden and Greece from an emotionsociological perspective. Do emotional regimes on a national level existand if they do, how do they differ? To answer this question qualitative interviews have been conducted withnine Greek/Swedes, men and women of different ages, who have lived in both countries and who speak bothlanguages. A quantitative survey study, employing a survey previously used in a Swedish study about emotions,has also been undertaken. Previous studies have shown that emotional regimes do differ historically and acrosscultures, but no study so far has focused on the differences between examples of North European and SouthEuropean cultures.The theoretical framework consists mainly of Hochschild´s theories about feeling/display rules and emotionwork, but the analysis also draws on Collin´s theory of interaction ritual chains and on Sociology of Emotionsmore broadly.The results suggest that different national regimes can be distinguished primarily in terms of display rules andin the skills of emotional alternations.

Cirkelträning - en kombination av styrka och kondition

In Sweden the amount of people with obesity has increased with almost 50 % during the past 20 years and is now including 500 000 people. A larger energy intake than energy consumption is today one of the most important cause of overweight and obesity that exist in the world. This requires more knowledge about healthier eating habits combined with moderate intensive exercise, exercise that is simple, effective and amusing. A god solution is a combination of fitness training and strength training, a type of circuit training. It is distinguished by a high intensive work in short periods and with a short break.

Småskaligt vattenkraftverk i Nyköpingsån

Interest in alternative energies is high in Sweden today, particularly in the agricultural sector. According to the Swedish lantbruksbarometern (2009), almost all respondents consider the use of some form of alternative energy from the farm. While interest in alternative energies is large, attention to the alternative energy straw has fallen and is almost nowhere mentioned in the literature today. Three years ago, in the Lantbruksbarometern nearly 44% of the farmers would be willing to invest in straw as heating system on the farm. How do the farmers decide to invest in alternative energies? With this information a problem is presented for this paper.

BAMBUVISKOS ? En hållbar fiber för framtiden?

Naturskyddsföreningen gav författarna uppgiften att undersöka förekommande viskosprocesser och alternativa regenereringsprocesser, detta för att identifiera hur hållbara de är ur ett miljöperspektiv och vilka processer som går att applicera på bambu. Detta för att se möjligheten att märka bambuviskos med Bra Miljöval och för att klargöra frekvent uppkommande frågor angående bambuviskos. Syftet är att se på de olika processernas kemiska innehåll samt vilka utsläpp de orsakar till luft och vatten. Ett delmål med rapporten är att den ska kunna användas som material vid vidareutveckling av kriterierna för Bra Miljöval Textil. Resultat som erhållits vid jämförelser av studerad litteratur är att de betydande faktorerna för miljöpåverkan från massaframställningen samt viskos- och lyocellprocessen beror av: använda kemikalier i processen, energianvändningen och vilken typ av energi, möjligheten till rening av utsläpp till luft och vatten samt återvinning av energi och kemikalier.
