Sensory studies of an energy dense drink for elderly people
The average length of life is increasing in the western world, hence the older population is growing. A common health problem among the elderly is malnutrition.
Malnutrition causes decreased body strength and is associated with an amplified risk of infections, depression, fractures and increased mortality. The health
care system is therefore faced with the challenge to prevent malnutrition among the growing population of elderly. This could be done by providing nutritious
foods developed to meet the specific needs of elderly. The overall objective of this project was to test a healthy energy dense drink based on oats targeted for the elderly
consumers as a strategy to prevent malnutrition among elderly.

Utsikten : Hållbara uppvärmningsalternativ för vandrarhemmet på Finnhamn
Finnhamn is a small group of islands in the Stockholm archipelago. At Stora Jolpan, the biggest island, there is a hostel. The main building was built in 1915 and is called Utsikten. The purpose of this project is to on behalf of the Archipelago Foundation (Skärgårdsstiftelsen) find alternative systems that can replace the existing heating system of Utsikten (an oil-fired boiler and electricity heaters) to a system with renewable energy. The alternative system that this project focuses on is a system of solar collectors combined with a wood chip boiler.
Bearbetning av befintligt bostadsprojekt med syfte att uppnå passivhusstandard
I detta examensarbete har energiberäkningar och analyser enligt FEBY12 gjorts på ett radhusområde för att undersöka vad som krävs för att lågenergihusen ska uppnå passivhusstandard. Att uppföra energisnåla byggnader är i dagens samhälle viktigt för alla företag eftersom människor blir allt mer energimedveten och krav från beställare blir allt högre. I arbetet har en modell av radhusområdet modellerats i Revit Architecture för att på ett smidigt sätt få korrekta värden i de olika energiberäkningsprogrammen Vasari, Energihuskalkyl och PHPP. Programmen har helt olika kvalitéer därför har en jämförelse och analys av programmen utförts. Analyser har tydligt visat att det krav som finns för att uppnå passivhusstandard på värmeförlusttalet är betydligt svårare att uppnå än det krav som ställs på den levererade energin. För att uppnå passivhusstandard vidtogs diverse åtgärder såsom U-värde för väggar förbättrades, ventilationsaggregatets verkningsgrad höjdes samt fönsterpartierna reducerades avsevärt. .

Tjustempiren : fallstudier av Casimirsborg och Blekhem
This paper concerning the regional architectural term known as the Tjust Empire style analyses manor houses built in the Tjust area by the east coast of Småland in the period 1810-1860. The term Tjust Empire style was invented in 1937 by PhD. Manne Hofrén in his dissertation on architecture in Kalmar län in the period 1650-1850. The aim of the paper is firstly to determine whether there is a distinct difference between the regional Tjust Empire style in architecture and the common Swedish empire style or as its Swedish equivalent is known; the Karl Johan style. Secondly, the paper strives to analyse why and how the Empire style became so popular in the area during this period, focusing on architecture as a means to express social identity and status.
En kvalitetsanalys av EU:s direktiv om förnybar energi
There's no doubt today that mankind has contributed to the changing climate byher use of fossil fuels. This must change in the nearby future. The Europeanleaders are expressing concern that renewable energy sources are not beingused to their full potential. The 2001/77/EC Directive on Electricity Productionfrom Renewable Energy Sources was accepted in 2001 to encourage thedevelopment of energy production from renewable sources, which isconsidered a step towards the fulfillment of the goal of the Union, that 12% ofthe gross energy consumption should come from renewable energy sources bythe year 2010.The objective of this thesis is to illuminate the common legislation of the EUregarding renewable energy with regard to goal fulfillment, judicial quality,conflicts with other goals of the EU and other faults. The objective is reachedby a hermeneutic study in which interpretation of written text is the mainmethod.
Energiaspekter på gestaltning : fallstudie Energihuset i Uppsala
This thesis has been carried out at the Department of Urban and Rural Development at SLU Ultuna during the spring semester 2009. The topic of the paper is how energy consumption can be influenced through design and if the conditions for good design decreases when solutions based on energy efficiency are used. The report is divided into one literature study and one part where energy efficient solutions are used in a design. The thesis work has its origin in a project called "Energihus i Uppsala." The planned building will be a center for energy research in Uppsala. The project aims to demonstrate to the public what is currently happening in research related to energy.
Vätskekopplade värme- och kylåtervinningssystem Utveckling av ett verktyg för energiberäkningar
According to a decision of the European Commission, measures are to be taken to reduce the use of energy in the EU. The goal is to reduce it by 20 % compared to the current use. This shall be done to the year 2020 (European Commission, 2011). One industry that use large amounts of energy is the construction of buildings which account for almost a third of the energy use (Brogren, 2012). The major part of the energy that is used in the construction industry is not used when the buildings are built, but rather during the rest of their subsequent lifetime.
Hydraulisk och termisk grundvattenmodellering av ett geoenergilager i Stockholmsåsen
Geothermal energy can be extracted from an aquifer, where the groundwater is used as heatexchange medium while heat and cold are stored in the surrounding material in the aquiferand to some extent in the groundwater. Application of aquifer storage for the use ofgeothermal energy is mainly used in large scale facilities and is limited to sites with suitableaquifers in the form of ridges, sandstone and limestone aquifers.Löwenströmska hospital in the municipality of Upplands Väsby, north of Stockholm, islocated nearby the northern part of the Stockholm esker. This means that it can be profitableand environmentally beneficial for the hospital to examine the possibilities of aquifer storagein the esker material next to its property.The purpose of this master thesis has been to investigate if geothermal energy storage with aseasonal storage of heat and cold can be applied within Löwenströmska hospital?s propertyarea using groundwater modeling. A hydraulic groundwater model was constructed inMODFLOW based on a simplified conceptual model of the groundwater system.
Bluetooth Low Energy som trådlös standard för hemautomation
Allmänheten har en stor efterfrågan av produkter inom området för hemautomation. Den senaste bluetoothstandarden Bluetooth Low Energy skapar nya möjligheter för intressanta produkter som underlättar vardagen. Lösningar som IR och Wi-Fi ger inte de förutsättningar som krävs för att på ett energisnålt och praktiskt sätt erbjuda sådana produkter, något som Bluetooth Low Energy gör. I denna rapport diskuteras standarden i syfte att redogöra för hur den kan användas för att automatisera ett hem.För detta examensarbete implementerades en strömbrytarprototyp och en iOS-applikation, vilka användes för att unders öka och påvisa ett koncept för hur tekniken kan tillämpas för hemautomation. Resultaten visar att teknikens räckvidd är dess främsta begränsning.

The effect of new raw materials on pellet prices
As demand for renewable energy is increasing rapidly, the market for biomass pellets
is expected to continue to grow in the near future. Most of the new raw materials that
are discussed for pellet production have one thing in common; the production costs
will increase compared to using traditional raw materials such as sawdust and planer
shavings. The aim of this thesis is to investigate to what degree increased use of new
raw materials for pellet production will affect the general pellet prices in Sweden and
to survey what plans Swedish pellet producers have concerning new raw materials.
To investigate the raw material situation of the Swedish pellet producers an industry
survey was performed. Literature studies were also made on previous research in the
subject field. Calculations of the production costs for pellets were done for the raw
materials sawdust, wet sawmill chips and energy wood respectively.
New raw materials are already used by the large-scale pellet producers in Sweden.
Det medeltida Fårö : en empirisk studie av tre husgrunder på en medeltida ödegård
The aim of the study was to through empirical studies interpret the relation between three partially investigated house foundations, on an abandoned farm in Langhammars on northern Fårö. This relation focused upon two main questions; the time of use and the spatial distribution of the archaeological finds.Trough comparative analysis two of these houses can establish to have been contemporary, the third one is too roughly examined. A discussion about the hypothec idea of two or three contemporary farms was made with a negative result.In house 1 smaller processing of tools of flint has taken place near the fireplace in the larger room. A concentration of pottery was also visible near the fireplace, likely to be connected to cooking and eating. The smallest room in the northeast part of the house could have functioned as a storeroom and/or held workshop activities.The archaeological finds and the distribution of it, strongly indicates that house 1 mostlikely consisted of a dwelling house and house 2 functioned as a workshop; linked to activities with handicrafts.
