Värdering och jämförelse av kvalitetsfaktorer för lokal kollektivtrafik i Helsingfors och Göteborg
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.
Kalkylarbete för byggnadsprojekt med Vico Office : För- och nackdelar med 5D BIM
AbstractBuilding Information Model/Modeling/Management (BIM) is a tool that allows for efficient working methods. BIM saves time and money while providing the potential for visualization. This method of working is based on a 3D-model, and then a fourth and fifth dimension are connected. 5D modeling means that a spreadsheet creates cost estimates based on the 3D model. This provides opportunities to carry out calculations in the early stages of the projects. Calculations are currently performed manually and do not contribute to the development that the construction industry requires.
Vad kan skriftspråk avslöja? : -en jämförande studie av barn med och utan läs- och skrivsvårigheter
????The aim is to examine how written production differs between students with and without difficulties in writing. The study also examine how different difficulties within writing interplay. It is based on analysis of ten-year old student texts with 30 texts from both an experimental and a control group. Texts were written in 1991.Both spelling, technique of writing and syntactic complexity differ between the groups.
Hej Litteraturen! : En studie av ett läromedel i litteraturhistoria ur ett genusperspektiv
The purpose of this study is to examine, from a gender perspective, Utbildningsradions TV-program Hej Litteraturen! in the light of feminist literature studies conducted during the last twenty years. I want to examine if the feminist literature studies have had any impact on contemporary teaching material regarding the question of how much space in time is given to men versus women and which female authors are included in the literary canon. Hej Litteraturen! is a TV program produced in 2010 intended for high school teaching of literature history. By conducting a content analysis in which I divide the study in a quantitative and a qualitative component, I have investigated how much space and time is given to female writers and how they are presented. My analysis draws on use Yvonne Hirdman?s theory of the gender system. The result shows that the female authors get 37 percent of the total reference space and 42 percent of the time-space. The program has sought to describe male and female authors equally and gives them weight and relevance to the sections in a similar manner. In conclusion, Hej Litteraturen! is a tutorial which embraces parts of the criticisms that have existed in historical literature review papers in general and literary history textbooks in particular. Hej Litteraturen! has worked on gender aspects of the program and by picking up contemporary authors as reference points for literary history in the present, the program contributes not only not only in renewing the literary canon, but also in balancing out the dominance of male writers in the history of literature..

SMED implementation vid slipoperation
The thesis has investigated how Sandvik Coromant could implement the SMED principle on one of their grinders groups and what improvements it would lead to. The aim of the thesis is to identify the current situation and investigate how their setup times would be affected by SMED. The work initiated with a literature analysis about the SMED principles and then proceeded with an analysis of the current situation where the activity was time mapped. The analysis consisted of time trials of the process that the thesis would include. The time studies revealed opportunities for structural improvements to create environment for a more structured process.

Lärarundantaget - Om patenträttigheter vid universitet och högskolor betraktat ur ett principal-agent perspektiv
Rapporten syftar till att belysa och analysera den svenska lagstiftningen som har kommit kallas lärarundantaget ur ett mikroekonomiskt perspektiv. Lagtexten reglerar patenträttigheter främst mellan enskilda forskare och högskolor. Syftet med analysen är att kommentera eventuella ekonomiska effekter på utformningen av system för ersättning och dess effekter på incitament att bedriva forskning. Ett resonemang om effektiv riskdelning vid kontraktsformulering förs även. Rapporten bygger främst på ekonomisk litteratur och artiklar publicerade i tidningar med ekonomisk anknytning.
Involvering och värdeskapande i portföljföretag : Statliga och privata venture capital-företag
The major difference between venture capital-firms and other financiers is that their business idea is not only providing capital but also knowledge in business development. The ownership structure of an venture capital-firm can be private as well as public. The Swedish government is today one of the major actors in the Swedish venture capital-industry. The purpose of this study is to shed light on how venture capital-firms involve itself in its portfolio firm and if this contributes to an increased value of the portfolio firm. We also try to shed light on differences in how a public and a private venture capital-firm gets involved in its portfolio firm and if there is any difference in how they can contribute to added value.We have chosen to interview two public and two private venture capital-firms and one of their portfolio firms.

Ohälsa och effektivitet ? en uppsats om effektivitet och informationsproblem på Försäkringskassan
Frånvaron av priser och förvirring kring vem som konsumerar tjänsten gör att effektiviteten i sjukförsäkringsadministrationen inte kan bedöms utifrån den gängse nationalekonomiska definitionen. I denna uppsats definierar jag kriterier för effektivitet i handläggning av sjukförsäkringen. Vad och hur mycket som skall produceras bestäms av politikers efterfrågan. Hur det skall produceras på rätt sätt varierar mellan olika sjukfall. Utifrån dessa kriterier analyseras därefter lösningar på ett principal-agentproblem inom Försäkringskassan.

Aspektorienterade vittringsprocesser : En studie i ett nordiskt klimat
Weathering on rocks is an important component of the world?s geomorphology. One way to measure weathering on rocks is to analyse rock hardness. This is a study conducted in the northern hemisphere on granite rocks in Uppsala, Sweden. A Schmidt hammer is used to create a correlation analysis between the aspects on three glacial erratic boulders and rock weathering.
Marginaliserad kunskap? ? En kritisk studie av representationen av genusvetenskaplig litteratur i klassifikationssystem och ämnesordslistor
The main focus of this master?s thesis concerns the relation between subject representation, power and gender. Classification systems and subject heading lists are products of their cultural and social context and some subjects and disciplines are given a greater value than others. Our aim in this thesis is twofold; to discuss and critically analyse the prevailing gender norms that are expressed trough classification systems and subject heading lists and to examine how they manage to represent gender studies as a multidisciplinary subject in theory as well as in practice. We are also discussing the particular problems with the representation of multidisciplinary subjects in general.
Ventilhus för salivsug i dentalutrustning
The purpose of this work is to find out if the suctionvalve to the salivaejector for dental equipment in a simple way can be improved or if a new design is needed. The result of the examination of the suctionvalve shows that the friction between the piston and the seal is high and that this causes the valve in a few cases sheaves. The study concluded that only small changes in material or detail, improve the component..
