The purpose of this master thesis is to investigate if the mobile library has a similar role as the public library. To study this further we intend to examine the value and function of the mobile library. Answers are sought to the following questions: Can the mobile library be seen as a public library in a smaller scale? How do the users experience the value and function of the mobile library? What does the library staff think of the value and function of the mobile library for the users? What would the consequences be if the service of the mobile libraries would not exist? The method used was qualitative interviews. The groups of respondents are mobile library users and library staff.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

The purpose of the study is to explore how social media can be used as a forum to discuss politics and also how young people use critical reflection to evaluate the information available on social media. To achieve the purpose, a qualitative research is used. The empirical data is collected through semi-structured interviews with six high school students who voted in the Swedish parliamentary elections in/of 2014. The empirical data were then analyzed based on previous research on social media, and the school's mission to foster individuals who think critically. The analysis is also based on the theory of deliberative democracy model.

WesDyne TRC sysselsätter sig med oförstörande provning av Kärnkraftverk, både i Sverige ochutomlands. WesDyne TRC tillverkar och konstruerar robotar vilka är kapabla till att utföra dentyp av inspektion som efterfrågas av kärnkraftverken.En av dessa inspektionsrobotar är T-skannern, en smal robot vilket gör den lämpad till att utförainspektionsarbeten i smala spaltutrymmen. Fyra sugkoppsmoduler får manipulatorn att fästa motreaktortanksväggen. Detta genom att skapa undertryck med hjälp av trycksatt vatten. Dettrycksatta vattnet regleras med hjälp av ventiler.

Denna rapport är resultatet av ett examensarbete som har utfört på Security Qube System, SQS, i Skellefteå. Med filosofin att tjuven aldrig ska belönas konstruerar och tillverkar SQS värdetransportväskor med ett patenterat skalskydd. Väskorna är designade för transport och lagring av sedlar, lösa eller packade i plastpåsar, samt ATM kassetter. Deras problem är att väskorna blir tunga, svårhanterliga och har otydliga gränssnitt. Uppgiften har varit att utveckla en värdetransportväska, ämnad för en ATM kassett, med avseende på design, funktion och användarvänlighet.

A cars powertrain consists of everything that is needed for its propulsion. The components in the driveline that transfer the power from the engine to the driven wheels are not absolutely stiff, hence they will wind up due to the torque and act as torsion springs. If you suddenly demand a bigger torque by stepping on the accelerator pedal, a so called tip in manoeuvre, and that torque is acquired from the engine as quickly as possible, the driveline will not be able to transfer that fast torque change due to its weakness and as a result it will start to oscillate. These oscillations will be transferred to the driven wheels and make the car to accelerate jerkily which will be experienced as uncomfortable by the passengers. Furthermore, there is a backlash in the driveline that will make the weakness in the driveline even more excited than it should have been if the backlash did not existed.To avoid too big problems with these oscillations there is a control system that controls the demanded torque.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

I denna studie behandlas området långsiktigt digitalt bevarande, med fokus på digitala signaturers lämplighet för autenticering av digitala handlingar. Den teori som beskrivs tar upp vad en digital signatur är, vilka problem dessa har på lång sikt samt konceptet Trusted Archival Services som ett koncept för arkivering av digitala handlingar. Det empiriska materialet har samlats in genom intervjuer med tre valda respondenter. Dessa respondenter har valts utifrån deras praktiska erfarenhet inom detta område. De slutsatser som har kunnat dras av studien är att digitala signaturer inte är en lämplig teknik för att säkerställa autenticiteten i digitala handlingar på lång sikt.

The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.

A prefabricated timber frame house previously built by Villafabriken AB has been modeled in Autodesk Revit Architectural, a 3D-program based on BIM-technology. This has been done tosee if it?s possible to produce the publications that Villafabriken demands from the designengineer?s work, and examine which possible extra values that may arise compared to traditional 2D-CAD drawing.BIM is short for Building Information Modeling. Everything is stored in a single database and a change in the project file is automatically updated across the project. BIM provides more than just drawings since information from the model can be retrieved in various ways such as lists and quantity schedules.It was possible to produce the publications that Villafabriken demanded using Revit, but BIM doesn?t only mean a new way of drawing, it also require a change in the company?s process were the information from the model is being used..

Ericsson?s factory in Kumla, Modules Kumla, became a hub for radio modules and micro base stations, which enables mobile communication through radio base stations, in 2004. Because of this the factory focuses more on the logistics operations. This has led to a need to be able to plan the capacity for the materials handling system. This master thesis has therefore been performed at Modules Kumla to develop a capacity calculation model for the material handling flow during the autumn of 2005.The work has contained a mapping of the material handling flow regarding to which activities was performed and how much time they consumed.

The purpose of the essay is to analyze the welfare state from a gender perspective. Further, the paper analyzes and critically examines three different normative solutions provided by Irish Marion Young, Nancy Fraser and Jürgen Habermas for the realization of a welfare state that includes women.Habermas argues that the welfare state has created a situation of dependency and state paternalism which reduces both individual and collective self-determination. Young follows Habermas? argument. She argues for a political climate where justice is reduced to the distribution of material goods rather than the elimination of underlying relations of domination and gender specific patterns.

Examensarbetet har utförts på Metso Refiner Segments AB i Hagfors, Värmland. Gjuteriet arbetar mot pappersindustrin och produkten de tillverkar kallas för malsegment. Malsegmenten sitter monterad på två stora skivor i en raffinör, vilket används för att framställa mekanisk pappersmassa. För att minska personalkostnaderna och för att få bort ett monotont moment för operatörerna vill Metso automatisera den station där malsegmenten härdas. Värmebehandlingen sköts idag av två operatörer och är tänkt att efter en automatisering kunna skötas av en operatör.

Målet med detta arbete är att hitta en lämplig lösning för lastsimulering vid test av bussar.Projektet utfördes i samarbete med Laxå Special Vehicles (LSV) som ska bygga entestbuss åt Scania.Scania har tidigare en testbuss med ett lastsystem som ska bytas ut när det ska byggasen ny testbuss. Uppgiften i detta arbete blir att ta fram och utveckla ett helt nytt lastsystemför den nya testbussen. Information om den buss som ska byggas har samlats in ochutifrån detta har via brainstorming framkommit flera möjliga lösningar som sedan harutvärderats.Metodiken som projektet arbetat efter är systematisk konstruktion enligt Johannesson,Persson och Pettersson (2004). Denna metod kan delas in i fem steg,Produktspecifikation, Konceptgenerering, Utvärdera koncept, Detaljkonstruktion ochslutkonstruktion.Det lastsystem som Scania använder idag har några nackdelar, bland annat att det ärbesvärligt att ställa om systemet från ett lastläge till ett annat. Samt att det under vinternär problem med att systemet fryser då systemet använder sig utav vatten somviktmedium.Ett av de lösningskoncept som tagits fram valdes att arbeta vidare med till enslutkonstruktion.
