The objective of this Bachelor?s thesis is to investigate how the public library in Luleå has set about implementing an alternative classification system for its children's books section and to explore why this was done. We wanted to investigate both how they have adapted the new system to the children's own way of seeking information and the library personnel's experience of using the new shelving system. We have done seven interviews to answer these questions and our choice of literature is intended to put the process of change into a wider context. The answers show that the library was dissatisfied with the former system and have instead expressed a desire to shift the focus of their classification system to their users.

The aim of this paper is to examine how The Swedish Library Classification System, also known as the ?SAB-system?, has classified popular music. The investigation is limited to the classification category of ?Yx Jazz, Rock and Popular Music? within the SAB-system. The development of this category is studied.

Denna explorativa studie beskriver hur den interna kontrollen i organisationer kan påverkas under implementeringen av ett ERP system. Intern kontroll är en del av organisationens ekonomistyrning och består av organisationens rutiner och aktiviteter för att undvika risker och säkerställa att organisationens mål uppfylls. Eftersom implementeringen av ett ERP system är en riskfylld process är det viktigt att förstå hur den interna kontrollen påverkas. För att undersöka detta används i studien ramverket Internal Control - Integrated framework. Datainsamlig genomfördes på en stor IT-organisation där ERP systemet Navision 2009 implementeras och 10 respondenter från olika avdelningar intervjuades.

Sekretessbelagd.

Gamification är en strategi som använder spelmekanismer och spelkomponenter för att skapa motivation och engagemang hos användare av olika typer av system. Denna studie syftar till att undersöka om gamification kan användas för att motivera användare av system för tillverkningsindustrin.Studien har genomförts med en initial litteraturstudie och kvalitativa intervjuer med experter inom gamification samt utveckling av system för tillverkningsindustrin. Intervjufrågor har därefter ställts mot tidigare genomförd forskning, för att identifiera möjliga resultat.Resultatet av denna studie visar att spelmekanismer och spelkomponenter skulle kunna användas i ett system för tillverkningsindustrin, förutsatt att det finns ett tydligt affärsmål, mätbar och användbar data samt identifierade drivkrafter hos organisationens maskinoperatörer. Vidare har ett antal punkter identifierats som kan vara motiverande för en användare av system för tillverkningsindustrin:Möjlighet för operatörerna att följa utvecklingen i sitt expertområdeKartläggning av operatörernas drivkrafter, vilken därefter används för att förbättra operatörernas arbetssituation, med exempelvis mer givande uppgifterBelöningar som utdelas är matchade mot operatörernas preferenser, med syfte att vara mer effektiva som motivationsskapare.

This report describes a master thesis performed at Saab in Arboga. The main purpose was to build a controller for a system containing a turn table and an antenna beam. The idea is to use this system on a boat where it will be exposed to position disturbances due to waves. The desired behaviour is that antennas placed on the antenna beam should point towards the same target all the time. To solve this problem the system has been modeled and simulated in Matlab and Simulink.

A system for sampling of alcohol and aldehyde from diluted exhaust gases from vehicles powered by ethanol has been developed and tested. The major part of the work has been research of earlier work in the field and the construction of the sampling system.The part of the system constructed for the measurement of alcohol has been shown to work, however, more test should be performed. The part of the system constructed for the measurement of aldehyde was tested parallel to a commercially available system, based on the same principle of measurement, and has been shown to work well.Determination of the concentration of gaseous ethanol using a FID has shown the since earlier known fact that a FID is not able to measure a correct concentration of ethanol. Furthermore it has been shown that high concentrations of gaseous ethanol can not be kept in a bag more than a few minutes without a substantial decrease of the measured concentration..

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.

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

As companies grow, their need for computing power will increase, which traditionally resulted in companies having to invest in more IT resources. Now, with cloud computing, companies can easily hire computer power over the Internet, on-demand. Cloud computing offers a highly scalable environment where companies can store data and host their services. This paper employs a qualitative study with interviews and literature studies to explore opportunities and challenges associated with cloud computing from a system developer perspective. The aim of the paper is to find out how cloud computing changes the conditions for system development. The paper contributes with four different opportunities and challenges that the system developer must handle to succeed in the world of cloud computing.

A large amount of our time is spent indoors in an artificial climate. To make the experience pleasant there are requirements on the ventilation and the heating system. At the present time the most common form of heating is a radiator system complemented with a ventilation system. A ceiling heating system with combined heating and ventilation can replace the two separated systems. The benefit with a ceiling heating solution is that it saves space since the radiator system is no longer needed.

The thesis describes a completely new biofuel system to generate particle-free heat from combustion of ash-containing biofuel particles at high temperatures.The suggested system gives opportunities to introduce biofuels in new areas.Main components in the suggested system is a heat radiating combustion chamber intended for pulverized wood, combined with regenerators to extract heat from flue gases and simultaneously preheating the combustion air.The thesis contains a description of the suggested system, theoretical considerations, calculations regarding the combustion, and includes results from tests performed.The results from calculations and tests performed concludes that the system is workable and possible to apply..

Syftet med undersökningen är att ta reda på om begreppet ?Tekniska system? tas upp i förskolan. Dessutom undersöks hur förskolorna arbetar med teknik enligt den reviderade läroplanen, Lpfö 98.Som metod användes enkäter där pedagoger satt i arbetslagsgrupper och besvarade frågor. Enkäten används för att få en bättre bild av hur ålder, kön, tidigare utbildningar och yrkeserfarenhet förhåller sig till kunskapen av teknikämnet.Undersökningen visar att alla förskolor använde sig av begreppet tekniska system på ett eller annat sätt i samtal med barnen, till exempel vid toalettbesök, samt frågor ?vart tar rören vägen vidare till reningsverket??Vidare framkommer det att fler fortbildningsdagar och studiebesök är önskvärt för att pedagogerna ska få en större vetskap om begreppet tekniska system.

The purpose of this Master thesis is to examine how college library managers perceive shelves of book reservation system in an integrity perspective. Privacy is an important part of everyday life in the society of today and according to some people, for example a former library lawyer in the Swedish Royal Library, these shelves conflicts with the Swedish law of Secrecy (Sekretesslagen 9 kap. 22 §). I am therefore interested in how they perceive this system: what weaknesses and strengths it has, why they implemented it, how they have interpreted this law. To answer this I have used a qualitative method called phenomenography and done interviews with five college library managers.
