Informationshantering kring nationella prov i matematik på gymnasiet

This work studied the information flow and information handling among different parties. The study focused on how educational materials on national tests from The Swedish National Agency for Education is managed by school principals and teachers and how the information is passed on to students. The data material was based on observations and interviews at two different high schools. Six teachers and their classes and principals participated in the study. The Agency was also interviewed.

Röstpremien - premien för aktiens rösträtt

This thesis aims to investigate the voting premium for companies differentiating voting rights between share classes on the Stockholm Stock Exchange. The voting premium represents the value of a vote attached to the share. The voting premium can be estimated from the price premium between two listed share classes with differentiated voting rights. Rydqvist's dissertation (1987) serves as a model for this study which investigates whether the theory of the so called "oceanic games", along with a proxy variable for cost of control, can predict the voting premium during 2010-2012. To the original model developed by Rydqvist, control variables for differences in liquidity between share classes are added to investigate for an increase in the explanatory power.

Utredning av reningsfunktionen hos Kungsängens dagvattendamm : en studie med flödesproportionell provtagning

Dagvatten kallas det regn- och smältvatten som rinner av från hårdgjorda ytor i stadsmiljön. Detta vatten för ofta med sig stora mängder av föroreningar som tungmetaller, näringsämnen och oljerelaterade ämnen, vilka kan göra stor skada om de når recipienter. För att rena dagvattnet och därmed minska föroreningsbelastningen byggs det allt fler öppna dagvattensystem som t.ex. våtmarker och dammar. Studier har visat att dessa system har hög reningseffekt och dessutom är de kostnadseffektiva.

Implementation av FlexRay prototypstack

FlexRay is a new communication protocol which is fast, reliable and flexible and therefore can meet the increasing demands on data communication in the vehicle industry. The protocol is developed by an industrial consortium containing among  others BMW, Daimler Chrysler, Motorola and Phillips. Today (May 2009) Hägglunds is using CAN for data transmission in their systems. CAN is getting obsolete and has difficulties in coping with the increasing flow of communication. In this report FlexRay and its communication capacity is studied.

Den moderna kommunikationen : En rapport om instant messaging och hur det används av unga vuxna studenter.

This paper describes the development of a simulation model for the ambulance flow in the Västra Götalands-region of Sweden, and an analysis tool for the output of the simulation model. The aim of the simulation model was to be able to evaluate the outcome from changes in the ambulance operations, such as a reorganization of ambulances or an increase in intensity of the ambulance calls. This evaluation is meant to serve as decision support for the strategic planning of the ambulance operations. The analysis tool was developed to visualize the abundant geographical data produced by the simulation model in a meaningful way. The simulation model was validated against historical data which showed that the dispatch time for the highest prioritized ambulance calls corresponds well with historical data.

Radialtätning till Retarder

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Att göra analoga objekt digitala : En kvalitativ studie om digitaliseringsprocessen i ett bibliotek

Contemporary libraries face challenges in transforming their organization to meet the digitalized society. To develop the process of digitization of literature is a natural way for libraries to go when they already have more visitors online than physically. Since the demand for digital material is so sought after, we feel challenged to address the challenges of the Internet as an emerging functional medium for distributing knowledge. These developments will be able to significantly modify the nature of literature as well as the existing system of quality assurance. In this study, we explored and analyzed a digitization project at a research library.

Det bästa för miljön, det bästa för Europa?- Europeiska kommissionens argumentation i frågan om EU-harmonisering av miljöskatter The best of the environment, the best for Europe?- European Commission' s official arguments on EU hormonisotian of environmen

This thesis tackles the subject concerning arguments as a conceptual basis forunderstanding the general strategy of the European Union Commission on issuesconcerning EU-harmonized environmental taxes, politically delicate and intergovernmentaldependent. The Commission's official proposals, communications and other relevant documents are subject to inquiry, where the theoretical bases are that harmonized environmental taxes in the EU is an issue conceived as supported by academic debate, and where the institutional arrangement in relation to an European-national dimension alongside the discursive context, allows meaningfulspace for arguments. The study makes a distinction between substantial (environmental cancerns in itself) and instrumental (other benefits, mostly economic ones) rationality as a foundation in various types of arguments.The study's main findings are that the Commission's official documents over the past 20 years, have been trying to keep a strong image of reason and knowledge based arguments for an EU-wide environmental tax reform. In particular, the types of arguments tend to appeal to the Member States by stressing the instrumental rationality in a European environmental tax reform, indicating the value of good arguments as a part of the Commission's main strategies. In sum, this may have further theoretical suggestions concerning questions of environmental and elimate change policies in a European context or other more general studies relying on theoretical assumptions of logics of argument, legitimacy or studies of motives behind action strategies in politically sensitive issues such as taxation at supranationallevel..

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

Irländska kvinnor vid the Old Bailey : Synen på irländska kvinnliga förbrytare i London 1674-1900

The Irish immigrants have been an important part of London throughout the centuries. Their presence can be found from the 17th century and onwards. Initially occupied as seasonal workers in agrarian fields the Irish later found alternative ways of supporting themselves as the Industrial Revolution transformed the whole of England. Despite their vital importance to the construction of what was to be known as "the modern Babylon" the Irish have been victims of both social prejudice and maltreatment. Some historians have imposed a comparison between the Irish in England and the African slaves in the United States.

Katalogen som tolkningsredskap : Bibliografiska relationer i Resource Description and Access (RDA), med särskild hänsyn till operationaliseringsproblem

The new cataloging code Resource Description and Access (RDA) provides a system of instructions for recording relationships between related resources by means of a controlled vocabulary of relationship designators. The purpose of this two years master?s thesis in Archive, Library and Museum studies is to examine the construction of this system, as well as its theoretical foundation. One theoretical point of departure is the necessity of operational definitions for consistent identification of bibliographic relationships. Another such point of departure is that the theoretical model on which RDA is based (the FRBR model) is not a complete description of the biblio­graphic universe, but merely a limited representation of a set of assumptions about that universe.The thesis first examines Barbara B.

Oxygen Health : Inlösning av syre i vatten

The project has been provided by Zenit design group and the goal for this project was tomanufacture and perform tests of a prototype that supersaturates water in a continuous flow ofwater. The project has involved finding and sorting out relevant data in scientific papers, books,communication with foreign manufactures and other platforms for information.The project has resulted in manufacturing of a test rig and an oxygen infuser based onmembrane technology. The test rigs purpose was to perform tests on oxygen infusers fordifferent comparison test and performance benchmarks in a in a laboratory provided by Zenit.The project led to satisfying results using the oxygen infuser manufactured by the authors withcomparable levels of saturation to the reference infuser.The theory behind this project is based on medical research, belonging terms will be explainedbut the authors have chosen to delimit the project from the medical area. The reason for this islack of knowledge in this area and its irrelevance to the mechanical engineering education insuch..
