Analys och förbättring av en mätenhet för laddning av elfordon
Reducing the CO2-pollution, resulting from the combustion of fossil coal for energyproduction, is important to affect environmental changes. One way to achieve a reductionis to use the oxy-fuel technology. The technology uses O2 and re-circulated flue gasduring the combustion which results in a flue gas mainly consisting of CO2. The flue gascould then be compressed and stored without environmental effects. A problem thatfollows from the compression is the risk of acidification in sensitive parts of the process.Acidification can occur because of reactions following from the contact of condensedwater and sulphur- and nitrogen-oxides which are also present in the flue gas.This report compiles and evaluates the basis of a scientific unit with the purpose ofexploring the possibilities of extracting impurities of SOx and NOx from the flue gases.The dimensions of the unit are based on basic conditions, defined for an existing oxy-fuelprocess at Chalmers, and on the results of computer modelling.
Digital doggy bag : iPhone applikation som tar med dina mat- och dryckupplevelser
In this project an iPhone application for storing food and drink experiences was developed with focus on an easy interaction design. The already existing market of similar applications were studied and evaluated to extract their positive and negative features. Interviews with experts within the food and drink business where made in the pre study to get a good perception of how to divide and categorize the sections in the application. To optimize the usability, workshops with potential users with different technical experiences where continuously held during the development of the design.During the development two variants of development environments where evaluated. The final result of the application was developed in the environment that made the best impression and seemed to be the best alternative.The resulting product has a thought out design meant to be easy to understand, even for the first time users.
Strukturerat lärande genom Action Design Research. En studie om visualisering av behörigheter
As organizations are generating more business intelligence in their systems, more employees need access those systems. As a result some sort of permission management needs to be implemented to ensure the information remain safe. Access Control Matrix (ACM) is one way of managing permissions and is widely used among organizations. The issues that comes with ACM is that the matrix itself gets difficult to manage and overview as its complexity increases with the number of permissions. The study utilizes Action Design Research to develop a tool for visualizing permissions.
Det offentliga rummets dragningskraft : En gestaltande fallstudie om offentliga rum i Hässleholm
The thesis is a case study that deals with public space based on how people use them. Public spaces are an important part of our city life and everyday life. Quality public spaces and places are due to its design and use, which are the primary aspects of this study. Hässleholm has been the location for the case study inventory items. Five different methods have been the basis for the study, and through them it has been possible to study what makes a room usable and unusable and what criteria is necessary for people to want to stay in the public rooms.
Crossmediadesign : Den unika processen
I denna artikel ämnar vi, genom att studera olika modeller med stöd för olika designsituationer, att skapa en modell som specifikt stöder design av crossmediaproduktioner då en sådan inte existerar i dagsläget. Genom att själva arbeta med en crossmediaproduktion för Non smoking generation fick vi chansen att på nära håll studera designprocessen och kunde på så sätt identifiera dess beståndsdelar och aktörer. Baserat på dessa och i kombination med teorier om design och crossmedia kunde vi skapa en egen modell som kan stödja framtida designers och producenter i deras arbete med designen av crossmedia..
Sjöars känslighet för klimatförändringar ? vilka faktorer påverkar?
The Earths climate is changing at a higher rate, i.e between 1861 and 1994 the annual mean temperature in Scandinavia increased with 0,68º C and according to recent climate models the annual mean temperature is likely to rise with another 3º C during this century.A warmer climate in many ways is associated with changing conditions for lake ecosystems. An expected higher water temperature and a stronger summer stratification of the water column increases the risk of anoxic conditions at the lake bottom. Thus anoxic conditions are likely to cause a phosphate leakage from the sediment, i.e. a higher internal loading of phosphate.In this project, the extremely warm summer of 2002 has been used as an example for a possible scenario for a future climate. By comparing levels of phosphorus in the summer of 2002 with a ten-year median value, a phosphorus related sensitivity to climate change has been analyzed for 55 Swedish lakes.
Prestandabaserad design genomkonceptuell energianalys : Performance-based design through conceptual energy analysis
This degree project aims to investigate the potential and possibilities for conceptual energyanalyses in the early stages of the design process. Many key decisions are made in theearly stages of a project regarding the shape and orientation of the building. Conceptualenergy analyses can provide the architects with insight regarding different design option?srelative energy performance.As the demands for more sustainable buildings increases, so does the need for earlyenergy analyses. Performing analyses in the early stage requires many assumptions andguesswork which could lead to a large margin of error.The offering from Autodesk is a module in Revit Architecture/MEP and the stand aloneprogram Project Vasari (under development).
Miljösystemanalys av alternativa avloppssystem i ett urbant område ?Svartvattensystem : Skogaberg ? Ett pilotprojekt i Göteborg
Starting point to this Paper is the idea and wish to adapt the society and its different activities to a recycle society. A building area in Göteborg is planned and investigated for such adaptation. In the district named Skogaberg, about 130 households totally are planned from what 20 are blocks of flats. The idea with this project is to constitute an alternative sewage system, a Blackwater system, were the fractions of most nutrients and least pollution are separated, taken care of and utilised. The aim is to get a market and use the nutrients of the organic waste from the household in agriculture use.
Föroreningstransport i grundvatten : En modelljämförelse
This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.
Tillagning i mikrovågsugn och dess effekt på livsmedel : En jämförelse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin. However, for the majority of nutrition values the differences are quite small.

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.
Vindpark Vänern : Fundamentteknik och Logistik
An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. Results from these test where used to calculate the treatment effectiveness and resulting energy potential at the mill.The literature study and constituent analysis showed that toxicity of the water to be treated, due to wood extractives and sulphur content, was of concern. Detoxification chemicals targeting these constituents where used in the anaerobic treatment trial.
