Regressionsmodellering av dynamiska råemissioner från statiska mätningar
By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.
Matematik : Hur motivera elevens lärande i köksmatematik?
In Adult Education-Restaurant students often have a negative attitude towards the subject of math. Often mathematics is associated with what experiences the students had of this subject in elementary school - experiences that many times reduce the motivation for the same that is so frequent in the catering industry, in different contexts. Mathematics more or less unconsciously permeates restaurant profession at large, and as a chef you must realize the importance of mathematics in your daily work in the kitchen. The purpose of the work is to develop the mathematics lesson weight and volume by planning and designing more stimulating lessons accommodated in the kitchen - combining calculation problems with the work in a real kitchen environment. The aim is to help increase the students? motivation for and understanding of the importance of mathematics in the kitchen work. An action-oriented research method was used where students in a survey were asked to answer questions about their previous experiences with mathematics and how they themselves thought that motivating lessons on mathematics in cooking should be designed. The survey revealed that the majority of the students thought that the mathematics lessons weight and volume preferably should take place in the kitchen.

Utvärdering av ett IR-system i en informationssökningsprocess ett holistiskt perspektiv
The research objective of this thesis was to conduct a holistic evaluation of an operational information system. By holistic evaluation we mean that an equal focus was placed on both the system system perspective and its users user perspective, in the actual environment where the system and its users function contextuality. In addition, the methodological objective of the study was to test a new research approach in a real life setting. The participants of the study were twenty newspaper journalists employed at Göteborgs-Posten GP. The information system NewsLink is a manually indexed full-text database containing all articles published in GP since 1994.
Pedagogiska miljöer : Barns och pedagogers uppfattningar om den pedagogiska miljöns erbjudande utifrån ett genusperspektiv
Background: Investors have several options to choose from when the goal is to achieve the highest yield at the lowest cost and risk. Stocks are a common investment options, but is also associated with risks. Portfolios are usually constructed with several different assets to reduce the unsystematic risk of investment. Funds are similar to composite stock portfolios, the big difference is that they dealt with in their entirety and investors may not affect the fund's content. The problem remains that whether you choose stocks or mutual funds there is still uncertainty as to how the future will unfold.

Ägande av hyresbostäder i Sverige : Marknadstrender under perioden 2006 ? 2012
The real estate industry is a sector where the companies generally have a capital structure which is high leveraged. The financing? with the related terms ? is therefore specifically of high importance for the companies in the sector. Traditionally, the way of obtain financing is by borrowing from the bank. Lately, due to new bank regulations, the banks have become more restrictive in their lending which have lead to a growth of other financing alternatives.
Finanskrisens påverkan på fastighetsbolagens finansiering : Alternativa finansieringslösningar
Denna uppsats behandlar hur fastighetsbolagens finansiering har utvecklats efter finanskrisen, hur finanskrisen specifikt har påverkat fastighetsbolagens finansieringsverksamhet samt i vilken utsträckning fastighetsbolagen har börjat använda alternativa finansieringssätt i sin verksamhet. Detta ämne är intressant då finanskrisen har haft en stor inverkan på det ekonomiska klimatet världen över vilket också inkluderar de svenska fastighetsbolagen och de svenska bankerna.Uppsatsen kombinerar en kvantitativ undersökning av alla svenska börsnoterade fastighetsbolagskapitalstrukturer med en kvalitativ undersökning bestående av ett antal intervjuer medrepresentanter från flera fasighetsbolag och banker.Den kvantitativa undersökningen visar att det skett stora förändringar i fastighetsbolagensfinansiering. Användningen av alternativa finansieringssätt, såsom preferensaktier, obligationer,MTN- och Certifikatsprogram har blivit vanligare i fastighetsbolagen. En stor anledning till detta är att bankerna i många fall har velat begränsa sin utlåning till fastighetsbolagen samtidigt som kreditmarginalerna har ökat på grund av bland annat högre kapitaltäckningskrav för bankerna.Utvecklingen av fastighetsbolagens finansiering kommer fortsätta framöver och alternativa finansieringssätt kommer i större utsträckning användas som komplement till banklån och stamaktiekapital..
En usabilityutvärdering av Umeå Universitetsbiblioteks OPAC
This is a heuristic evaluation of Umeå university library?s Online Public Access Catalog (OPAC). It makes use of four of Nielsen?s ten heuristics, flexibility and efficiency to use, match between the system and real world, visibility of system status, and aesthetic and minimalist design. The evaluation was done by having 3 evaluators inspect the interface individually, as per Nielsen?s (1990) recommendation of 3-5 evaluators.
vindkraftens påverkan på elkvaliten
This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.
Fastighetsinvesteringar
As a result of increased property prices on apartment buildings in Halmstad many local investors thinks that the market behaves illogical. This because these investors can?t find any profitability in many real estate transactions. The valuation between different investors on the same object therefore goes their separate ways. One example of this is a property in central Halmstad which starting price was about 23 million SEK.
Vad är bakgrunden till utländska investerares intresse av den svenska fastighetsmarknaden? : Why are foreign investors interested in the Swedish real estate market?
Den svenska marknaden för kommersiella fastigheter är het och har varit det under lång tid. Bland annat konstateras i en undersökning från revisionsbolaget Pricewaterhouse Coopers och Urban Land Institute att Stockholm, efter London och Paris, just nu rankas som Europas tredje mest attraktiva stad för utländska investerare att köpa och äga fastigheter i.Detta väckte vår nyfikenhet att konkretisera de faktorer som kan ha lett fram till att utländska fastighetsinvesterare attraheras av den svenska fastighetsmarknaden.Genom att vända oss till företag med stor inblick i de förhållanden som råder på den svenska fastighetsmarknaden fick vi intervjusvar från fem representanter.Arbetet med teorin gjorde att vi förväntade oss ett visst svar men intervjuerna gav oss ett helt annat resultat. Denna uppsats belyser många faktorer som gör Sveriges fastighetsmarknad lättillgänglig. Dock påvisar vår studie att framförallt transparensen och likviditeten på den svenska fastighetsmarknaden är det som gör den så intressant för utländska investerare.Transparensen på den svenska fastighetsmarknaden, som är en stor konkurrensfördel på den globala marknaden, hotas av skattetekniska konstruktioner. Att inte förlora denna fördel på den internationella investeringsmarknaden är ett problem som måste lösas.

Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle
The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable.
The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.
