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.

Purpose: The purpose of this thesis is to examine the ERK model's relevance, validity and potential need of development to better reflect how it looks today (2013). Method: The study is conducted through three surveys; the first two were face interviews with companies that sponsor Swedish soccer teams and the third study was conducted with a questionnaire to supporters outside a soccer stadium. Results: A model that would better reflect the reality of today (2013) could contain company pride, chairman?s whim, exposure, relationships and associations..

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.

The building industry are currently going through a huge alteration. The introduction of BIM (Building Information Modeling). 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.

The purpose of this comparative study is to investigate if the views of Sayyid Qutb and Tariq Ramadan regarding social structure and religion are possible to unite with western liberal democracy. The basis of the study is the problematizing approaches written by Qutb and Ramadan regarding the possible unity between Islam and democracy. These problematizing approaches are then tested on the political philosophy of liberalism to see if a unity is possible.The result showed that Qutb's view did not meet the criteria of democracy, which wasn't surprising due to his negative views on the system. However, Ramadan's reformist view on Muslim identity did unite with the views of liberal democracy, though questions regarding the possibility of creating and preserving a European Muslim identity in the secular society were immediately brought to attention.The importance in Qutb's view is social equality, unity and submission to God and the importance of Ramadan's view is to create and preserve a European Muslim identity and adapt to the society where you live and participate as a citizen. Qutb's view will not tolerate diversity and one is to keep or convert to the Muslim faith.

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.

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.

Företaget Radius Control Systems AB sysslar huvudsakligen med utveckling och underhåll av SCADA applikationer. Radius hade önskemål om att kunna visa väderinformation från en väderstation i Radius egna övervakningssystem Uni-View. Detta skulle ske via ABB: s styrsystem AC 800M/ 800xA, med en PM856 processor. Arbetet handlar om att upprätta kommunikation mellan en PLC och väderstation, och från PLC vidare upp till Uni-View. Rapporten behandlar hela arbetsprocessen med början från en prototyp till ett fungerande system.

As the western society gradually turns into a knowledge- and risk society, where science and scientific innovations increasingly both promise to save the world and destroy it, a shift in the relation between the scientific community and the rest of society has emerged. A shift from a top-down one-way transfer view regarding communication, to a dialogue-based interactive co-production model, where the public are part of setting the agenda for research and contribute to the knowledge production. Or at least in theory, in EU documents and in many different country's policy documents. In practical application however, one might have a hard time see the implementation of such model.As a more comprehensive and dialogue-based science communication is depending on the possibility for scientist themselves to engage and fell the need to engage, we have focused on their thoughts.In this thesis we have examined six scientists view on, and work with, science communication, as well as their perceived social and structural conditions. We have also examined action plans and strategy documents from three Swedish universities that in different ways mention science communication and interaction with the broader society.

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.

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.

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.

Rapporten grundar sig på en studie i att utröna möjligheterna för att förenkla och effektivisera Metrias kartproduktion genom användning av Arc View 3.1 samt Arc View tillsammans med Adobes programvaror Illustrator och Photoshop. Två kartor skapades under arbetets gång, en översiktskarta och en centralortskarta över Gällivare. Moment som ingick var: Terrängskuggning, adressättning, symbol- och färgsättning av kartor samt test av kartframställning med hjälp av Adobes programvaror. Olika höjd- och solvinklar prövades vid terrängskuggning. Adressättning av vägar gjordes till en interaktiv funktion där gatuadressen fördes över från fastighetsdataregistret till GSD-Ekonomiska kartans vägskikt.
