Statistisk behandlig av driftsdata : Ur Garpenberggruvans driftcentral
Boliden Mineral Ab's mine in Garpenberg, Dalarna is going through a massiveexpansion. The annual ore production is being increased from 1,4 million tons to 2,5million tons in less than two years period of time. Along this expansion thedepartment of mining techniques is administrating a project of optimizing the shortterm planning for the mining production. Garpenberg have since mid 90s storedinformation from all mining processes in a database.The information consists of time data from all the different activities required in themining process, for example charging, blasting, loading etc. The database also containstime data of delays that are affecting the production.
Utvärdering av möjligheten att tillvarata energi ur processvatten : En undersökning gjort vid Olofsfors AB på uppdrag av UMIA AB.
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Den globala uppvärmningen : vad kommer att hända med morgondagens värld?
Mankind faces a serious threat. Its activities, for example the burning of fossil fuels, have led to an enhancement of the greenhouse effect - something that has given rise to a global warming. The climate is becoming warmer, a change that has important effects on the nature as well as for humans and their society. Sea level rising, extreme temperatures are becoming more common, glaciers and other ice caps melt and storms becomes more intense when they appear. The main cause is the emission of greenhouse gases into the atmosphere - carbon dioxide in particular.

Brickbandets utemiljöer : vårdplan 2006
In the centre of Bromma, east of Brommaplan is the part of Bromma named Riksby. Riksby was built in the early 1940:s as a part of the westward expansion of Stockholm. Other places that were built at the same time was for ex. Stora Mossen and Abrahamsberg. This work is about the outdoor environment of the housing co-operative of Brickbandet.
Variation in frequency of alleles in the MTNR1A gene with possible impact on ability of ewes to show oestrus out of season
In Swedish sheep industry it is desired to have lambs slaughtered evenly distributed over the year. Swedish sheep are generally seasonal breeders with lambs born in the spring and slaughtered in the autumn. Some of the breeds, e.g. Swedish Finewool and Roslag sheep breeds have shown ability to lamb out of season. For increased knowledge on the possibilities to breed for out-of-season lambing in Swedish sheep breeds, the aim of this master thesis is to study the variation in frequency of two alleles in the MTNR1A gene in the three breeds; Gotland, Swedish Finewool, and Roslag sheep.
Flygallianser : Nyckeln till framgång
Vi ville med vår uppsats undersöka om strategiska allianser inom den internationella flygbranschen har lett till att medlemmarna i alliansen åtnjutit en förbättrad lönsamhet och expansion i verksamheten.Den alliansen vi hade fokus på för undersökningen var Star Alliance och vi granskade utvecklingen av de utvalda lönsamhetsmåtten hos de fem flygbolagen som var med och upprättade denna allians. Vi undersökte även lönsamhetsfaktorerna för fyra flygbolag, som för den studerade tidsperioden inte ingick i någon strategisk allians. Dessa användes som jämförelseobjekt.Urvalet gjordes utifrån att det var just dessa fem flygbolag som upprättade alliansen och att denna allians var den första av sitt slag. Urvalet av de fyra jämförelsebolagen gjordes utifrån att dessa var de få flygbolag av den traditionella typen som under studiens utvalda tidsperiod inte ingick i någon liknande allians.Vi genomförde undersökningen genom att samla information hämtad ifrån flygbolagens årsredovisningar från 1994 till 2004 och försökte upptäcka trendbrott i nyckeltalens utvecklingar efter det att Star Alliance upprättades. För att förstärka tillförlitligheten av undersökningen använde vi de fyra jämförelseflygbolagen och genomförde en statistisk hypotesprövning för att testa om det förelåg någon signifikant skillnad gällande utvecklingen av lönsamhetsfaktorerna mellan bolagen i Star Alliance och jämförelsebolagen.Resultatet av vår undersökning var att ingen tydlig lönsamhetsförbättring skett för bolagen inom Star Alliance.
Klimatanpassning med grönstrukturplanering : Med exempel från Malmö stad
Climate change is expected to lead to increased rainfall and higher temperatures, among other things. This will have a major impact on our cities. Floods can lead to property damage as well as damages to human and animal health. Higher temperatures will increase the frequency of heat-related health risks and premature deaths. The consequences of climate change will be particularly large in our cities because of the city's morphology with a high amount of paved surfaces and buildings that affect the natural processes in areas such as drainage and absorption of solar radiation.
Den interaktiva IR-forskningens genomslag i söktjänsterna på webben
The theoretical focus in this master is information retrieval (IR), and especially the part of IR that includes interactivity. This research is by some researchers called IIR. Our principal aim was to examine if search engines on the WWW are taking advantage of research results from IIR research. A way to do this is to look at the application of special features, in this case query expansion (QE) and relevance feedback (RF). Both these methods aim for a better matching of documents and the searchers information need.
Undersökning av förskolan Temmelburken certifierad enligt Miljöbyggnad : Termiskt klimat, energianvändning och höjning av certifieringsnivån
WSP building physics in Stockholm has certified the preschool Temmelburken in Bromma with the system of certification Miljöbyggnad. The rating of the building became BRONZE. In this thesis the preschool has been investigated with respect to the three areas: thermal climate, use of energy and improving of the level of certification. The thermal climate at the preschool has been investigated by a questionnaire survey and by measurements in order to do comparisons between the results from the two investigations as well as with the results of the simulations that WSP has done at the certification of the preschool. The differences between the results from the simulations and the questionnaire survey for winter as well as from the measurement performed with a comfort meter the 19th of March are concidered to be reasonably small since they give rise to the same rating according to Miljöbyggnad. Operational data for the use of energy for the preschool have been obtained in order to do comparisons with simulations performed by WSP and Svenska Besiktningar AB. The comparison shows that the simulated values for the specific use of energy are lower than what the real specific use of energy would be for the preschool, since just the operational data for the heat energy is higher than the simulated values. At the investigation of the possibility of improving the level of certification it was found that the rating of the preschool can be raised from BRONZE to SILVER by improving the ratings of the ?thermal climate summer? and the ?daylight?.

Fo?r att genomfo?ra studien har en kvalitativ studie genomga?tt i from av en flerfallsstudie med de svenska modefo?retagen; Odd Molly, Bjo?rn Borg och Hunky Dory.
E-handel 2005: en undersökning av olika betalsätt och företags påverkan på konsumenters tillit till betalning vid e-handel
E-handel kan definieras som köpande och säljande av information, produkter och tjänster via datornätverk. E-handel är ett effektivt sätt att utföra handel på då det erbjuder konsumenten många fördelar. E-handeln har expanderat kraftigt de senaste åren och beräknas växa oavbrutet under de närmaste åren. Ett av de största hindren mot denna beräknade expansion är konsumenternas bristande tillit till de betalsätt som erbjuds i dagens e-handelssystem. Konsumenter är helt enkelt osäkra att använda de betalsätt som existerar.

Förutsättningar för att utnyttja solceller i Sala-Heby relaterat till ekonomiska stöd
There have been several projects with solar installations in Sweden, and Sala-Heby Energi (SHE) wanted to create a solar plant. The question answered in this thesis is whether it is economically viable to create such a source of sustainable, renewable energy. The plant would be built with the help of the financial effort from 120 customers. This economic union would sell the electricity to the SHE, for SEK 4.50 per kWh up to a certain level over a period of 10 years. It would be a long term commitment to environmentally friendly electricity, using solar cells which convert sunlight directly into electricity.In year 2009 there was introduced a new state aid for photovoltaic systems, to create an increased and continuing interest in solar cells.
VINDKRAFTSETABLERINGAR : EN JÄMFÖRANDE STUDIE OM NÄRBOENDES INSTÄLLNING TILL VINDKRAFT OCH VINDKRAFTSETABLERINGAR I SVERIGE OCH BRASILIEN
To achieve a sustainable development, three aspects have to take equal place in the society; environmental, economical and social. To reduce the impact on the environment and the amount of greenhouse gases supplied to the atmosphere, industrialized countries and less developed countries must start cooperating. Also the use of renewable energy sources, like solar, hydro and wind power, have to increase.Wind power has great potential as a future energy supply. It is cost efficient, quickly developed and the resource is abundant and available worldwide.Examinations made in Sweden, indicates that there are difficulties establishing wind power at the same pace as the environmental goals, set by the Swedish government, requires. Mainly because people living nearby potential areas for wind power farms, appeal against the decision.This study aims to investigate differences between how people in Sweden and Brazil look at wind power as a future energy source and at the establishing process.
