Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

?The modern library in the network society?A study of cultural politicians and librarians opinions about libraries' use of social mediaSocial media is becoming more and more interacted in our daily lives and Carlsson (2013) argues that today's libraries have undergone major challenges in the digital information technology's entry in the library arena. The new technology has led to sum up in one question: how a library should relate to the digital information technology, the issue has applied in particular the social communications media, such as Facebook, Twitter and more. The purpose of this paper is to examine the culture of politicians and librarians 'perceptions of public libraries' use of social media linked to the libraries and their democracy promotion efforts. This is analyzed from Castells theories about the network society and the digital divide.In summary, the study concluded that the majority of the culture politicians and librarians believe that social media is a part of the future of the library.

The purpose of this study has been to examine the archival management at the 14 Student Nations in Uppsala. This may be relevant to study to extend the research in the field that Berndt Frediksson calls ?empirical archival science?. Another reason is that the Student Nations hold a unique position as organisations and their archivists holds a unique position from a professional point of view as they mostly consist of students without professional archivist training. I have mainly focused on why the archival management at the Nations looked as they did.

In 2011, I and fellow student at Gotland University created a multimedia game. To fit the time constraints a ?vertical slice? was created. This means a small sample of the game is taken which allows the user to understand how the game works, and at the same time, get a visual demonstration of how the game is designed. The goal of the project was to create a narrative for stadium games in which the backstory is told as players interact with their surroundings.

In a world characterized by increasing sustainability challenges, organizations are continuously facing new demands; creating new requirements of change management and incorporation of new strategic decisions. Today, organizations are responding to the emergence of new sustainability directives and regulations at a EU level, whence the latest sustainability framework CSRD (Corporate Sustainability Reporting Directive), becomes particularly relevant. Companies are therefore facing the challenge of integrating strategic management in their navigation, preparation and maneuvering of new directives; a transition that requires new strategic decisions and adaptations. The purpose of this study is to qualitatively examine how CSRD affects organizations in terms of corporate changes, operational adaptations and strategic decisions, as well as what capabilities are essential to incorporate. The study also aims to investigate relevant challenges and opportunities associated with the new directive.

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.

Since several rules of law have a consideration of age, the Swedish labor law collides in many ways with the prohibition of age discrimination. The employment directives of EU were implemented in the member countries after the shift of the millennium. Sweden was the last member to introduce age as a ground of discrimination in its legislation. The purpose of this thesis is to investigate whether the Swedish regulations, regarding age discrimination and its application, is compatible with the EU.  The aim is also to investigate what is required to exclude the prohibition of age discrimination. The labor law provisions concerning the retirement age given in 32 a and 33 §§ LAS, priority rules according to 22 § LAS and the collectively agreed holiday benefit, which is regulated according to a worker's age, is to be investigated to see if they actually qualify for the exclusion of the prohibition against age discrimination. Furthermore, the paper intends to describe if the Swedish legislation has taken account of the research available on the subject of "age" and ?age discrimination?.

The thesis deals with packaging of real estate?s; an approach concerning tax benefits with the purpose to sell real estates in a more beneficial process than what is doable in direct sales. The proceeding can be beneficial because of the rules in Inkomstskattelagen (19999:1229) regarding underpriced transfers and selling of business related shares.  The real estate owner initiates the procedure through an establishment of an affiliate to a previously wholly owned parent company, where the real estate is the solitary asset of the affiliate. In order to fulfill the rules of underpriced transfers the transfer from the parent company shall be valued in regards to the tax value, else it will be taxed.

The environment has become an important part in people´s lives, and in today´s society stakeholders demands have increased upon companies when it comes to sustainability reports. How these sustainability reports are designed depends on whom it?s for, laws and regulations, and the companies own norms and values. The purpose of sustainability reports is to measure, monitor and compare a company´s enviromental impact. It?s not only about integrating economics, but also enviromental and social standards together to get both financial and competitive advantages.Sustainable Value method is a new model and is the first real method that can be used to evaluate a company´s resources, both financial, social and enviromental to a sustainable value.This model is used to compare the resource efficiency between companies.In this thesis, a documentary study with an experimental approach has been made.Sustainability reports from six selected companies (in the engineering and forestry sector) have been investigated with respect to their accounting for carbon dioxide, and an experiment using the method ?Sustainable Value Approach? was subsequently performed.

This thesis suggest an explanation for is how it is possible to understand that the large arena project in Växjö grew to cost sums of money that initially in the project not would have been an alternative to discuss, how goals changed and how the institutional environment changed the prerequisites of the project. As empirical part of the research, to describe and analyze the project, the municipality?s documentation of the project have been analyzed and semi-structured interviews have been made. Theoretical perspective is taken from the neo-institutionalism in sociology of organizations and change, and theories of the complexity of large projects with major symbolic value and importance. The project starts with the municipality?s investment and cost to be hold back, defined as a necessary condition in order to fulfil an ambitious drive towards new sport arenas.  Eventually the necessary condition was abandoned and the arenas were built with the municipality responsible for the investment, cost and risk in the project.

The viscosity of air buildings is a hot topic within the construction performers, which the industry feel they have too little knowledge about. This study is mainly aimed against air density in apartment buildings and airflow measurement. The study consists of a theoretical reference, educational visit, interviews and a survey conducted among construction workers at Magistratshagen in Linkoping.Earlier requirement in terms of air leakage through the climate screen was removed and today there are only energy requirement for a dwelling in Boverkets Building Regulations. The difference between a passive and a typical air tight construction is that the passive house have a maximum requirement of 0.3 l /s m2 of air leakage through the building climate screen. The requirement imposed on passive houses is to minimize the supply of power and energy for heating the building.Air tight constructions have heavy demands on the performance and accuracy of everyone involved with the project. The client must specify their requirements and also be prepared to pay for any additional costs. The architect and building planners have to design the building with regard to air tightness. Finally, the construction workers are required to do a careful work in order to get all the connections in the building air tight.The study suggests that an air tight building is a closed system where no forced ventilation exists. There are no reasons not to build too tight as long as there is a functioning ventilation. In this study the authors ask themselves how an air tight building changes over time. No theoretical information has been found on these changes, but the respondents assume that air density decreases with time. The deterioration is mainly assumed to be caused by construction materials changes over time. The study shows that construction workers knowledge of air tight construction is mixed, which they themselves admit in the survey..

BakgrundLek har en stor betydelse för människans utveckling, då den ger oss spänning, glädje och lust. Leken är nära kopplad till fantasi och barn utforskar sin omgivning och formar sin personlighet genom lek. Leken är en arena där barn lär och utvecklas av och med varandra. Pedagoger skall i leken inta en medupptäckande roll samtidigt som pedagogen stöttar, utvecklar och driver lekaktiviteten framåt.SyfteI vår studie vill vi få kunskap om och analysera pedagogers syn på lekens betydelse för barns utveckling samt få kunskap om hur pedagoger använder sig av leken som ett pedagogiskt verktyg i förskoleklassen.Metod Vår metod är kvalitativ och vi har inspirerats av etnografi i vårt val av forskningsansats. I vår undersökning har vi observerat sex pedagoger, genomfört fältsamtal samt intervjuat fyra förskollärare i fyra förskoleklasser vid fyra skolor.

De förändringar som sker i arbetslivet med bland annat ökade krav, medför att det blir allt viktigare att bedriva folkhälsoarbete på denna arena. Det finns ett flertal studier som handlar om hur viktigt ledarskapet är, men endast en liten del av studierna tar upp chefers medvetenhet om ledarskapets påverkan på medarbetarna. Ledarens medvetenhet om sitt ledarskap har stor betydelse för medarbetarnas hälsa och chefen utgör den främsta arbetsmiljöfaktorn på många arbetsplatser. Syftet med denna studie är att studera kommunala chefers syn på hälsa, deras medvetenhet om ledarskapets påverkan på medarbetarnas hälsa samt känslan av ansvar för medarbetarhälsan. För att studera ämnet användes kvalitativ forskningsmetod med halvstrukturerade personliga intervjuer.

How does a social welfare officer know when a parent with mental illness or behavioral symptoms is harmful to the children? As a social you are confronted with different ethical dilemmas on a daily basis. The social welfare officers have to follow their own authorities, laws, guidelines and regulations while at the same time do everything to satisfy their clients? needs. This inconsistency can sometimes be difficult to handle.

Through certain exceptions in the Swedish regulation on credit agreements for consumers, a new form of instrument for credits has arisen on the national market. The instrument, which is most commonly known as easy credits and was first seen on the Swedish market for consumer credits in 2006, has developed to become part of a vast problem with excessive debt incursion. In order to counteract this development and to harmonise the internal market within the EU, directive 2008/48 EC on credit agreements for consumers was introduced in 2008. In Sweden, the implementation of the directive has led to a proposition for a new regulation on credit agreements for consumers (SFS 2009/10:242 Ny konsumentkreditlag) coming into effect on the 1 January 2011. The proposition puts up stricter rules on creditors granting consumer credits in their course of business, and revokes the former exemption on information and practices preliminary to the conclusion of the credit agreement for minor credits.
