Prediktion av villapris och dess faktorers inverkan.
A villas price depends on several important factors. By statistical data, a mathematical multiple regression model was modeled. The model has important explanatory variables such as living space, renovation year and standard points has been taken into consideration, in order to assess their impact on the final price for private homes.By using a statistical program,Minitab 16, the final model was selected with eight explanatory variables. The regression for this model explains up to 67.3 % of the variation on the final price.The results showed percentage wise that the standard points had the greatest impact on the price, there after renovation year and then living space..
Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.

Modellering och reglering av drivenheter i gaffeltruck
To enable the enhancement of the driver's environment in a forklift, an alternative form of steering has been evaluated. An earlier concept with a combined driving and steering wheel has been exchanged to a concept with two driving wheels. A link wheel has replaced the combined driving and steering wheel. The steering is done through differentiation of the velocities of the two driving wheels. The scope of this master thesis is to create a simulation model, create a control program and to evaluate the concept of two driving wheels.

Which also implements a lot of new ways of solving problems that building modeling can cause. This report is written for Uppsala University in cooperation with Temagruppen in Uppsala. However, it contains a comparison between two different systems that checks building models.
Kompatibilitet med BIM-koncept : Revit Structure 2012 och Robot Structural Analysis 2012
This thesis deals with the compatibility between analysis software Revit Structure2012 and Robot Structural Analysis 2012. The purpose is to become more aware ofinformation management models to be compatible across different softwareapplications. The structural model is made to be optimal for the compatibility of othersoftware Aim is also to gain an understanding of the transferring methods that exist,and which method is most convenient to use and to examine whether the methodswork in practice. Objective of this project is to make the modeling processtime-efficient for constructors. Models do not need to be structured in severaloccasions in different software; it only needs an optimal model that transfers properlybetween software.The method used in the thesis consist cases where the transferring process isexamined.
Dynamisk modellering av kärnreaktor
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
ABB Gate Model : En processledningsmetod för ABB:s produktutveckling
Organisations tend to focus more and more on product and process development to increase their competitiveness. Several major organisations, among them ABB, have developed models aimed to more effectively control and manage product development processes. ABB is using its standardised model ABB Gate Model for this. The purpose of this thesis is to analyze how the introduction of ABB Gate Model has affected the outcome of decisions and also the decision-making in the product development process. The study is limited to elucidate the version of ABB Gate Model handling product development projects.
Förändringarna i den tyska familjepolitiken : Ett steg bort från den konservativa välfärdsmodellen?
The purpose of this paper is to analyze the ongoing changes in German family policy. It explores the issue of whether the German welfare state, in this policy field, can still be regarded as a conservative welfare model or rather approaches a more liberal or social democratic model. A qualitative method is used to analyze the material, especially from the German government, including press releases, other public documents and also articles from the political weekly magazines Der Spiegel and Die Zeit. The changes analyzed are the new parental benefit, the expansion of child care, the concept of whole-day schools and the system of joint taxation. The point of departure is Gösta Esping-Andersen?s categorization of three types of welfare states: the social democratic, the conservative and the liberal.
Beslutsmodell för inköp och lagerhållning av motorer i ett produktionssystem : En fallstudie på Sandvik
AbstractIt is important to choose which spare parts to keep in stock. With the right spareparts in stock the costs for inventory and production loss will decrease. Cavalieri et al. (2008) highlights that the balance between inventory cost and production loss is underestimated. It affects the company and must be considered before decision on purchase.The problem with spare engines is that they are all more or less critical for the production. That can be a reason for why no previous research targeting engines and classification of with engine should be kept in stock has been found.

Verksamheters kemikaliehantering : En undersökning hur restauranger och lantbruk lever upp till lagstiftningen kring deras kemikaliehantering
Denna studie jämför hur Capital Asset Pricing Model (CAPM) och Fama-French trefaktorsmodell förklarar och förutspår avkastning på en global aktiemarknad. CAPM utgår ifrån att investerarna förväntar sig en riskfri ränta adderat marknadspremien multiplicerat med företagens exponering mot marknaden. Fama-Frenchs är en utvidgning av CAPM modellen, där företagens storlek och book-to-market-värde läggs till som förklarande variabler för avkastning. Genom regressionsmodeller och prediktioner för portföljer indelade i storlek och book-to-market jämförs modellerna. Fama-French tycks vara genomgående bättre på att förklara och förutspå avkastning under perioden 1990m07-2013m02 för samtliga portföljer, förutom portföljen för stora företag med medelhögt book-to-market värde.
