Det implicita avkastningskravet på Stockholmsbörsen: En jämförande empirisk studie med avseende på antalet börsintroduktioner för 1999 och 2012
This study examines the equity cost of capital between two periods distinguished by substantial differences in IPO activity. In light of the stemmed IPO flow to the Swedish stock exchange in 2012, this study regards the conjecture that the IPO count is related to the prevailing cost of equity capital for certain periods. By application of the Residual Income Valuation model the cost of equity capital is abstracted from sampled stock prices and compared at two points in time for which extreme highs and lows of IPO activity were observed. Using randomized samples from 1999 and 2012, significant differences between the estimated costs of capital are established. The findings indicate that the equity cost of capital, much as it may help influence, nevertheless plays a subordinated role in the going-public decision..

Kalvutdragaren - en hjälpande hand? :
The calf extrator?s function has been studied, through measuring traction and how
this varies in different situations, in comparison with corresponding manual
traction situations. This was done against the background that excessive force at
assisted calvings at dystocia can mean life threatening damages on the calf such as
grave acidosis, vertebral fractures, femur fractures and rib fractures. The calf
extractor has earlier been measured to pull with greater force than the established
maximum force of ?two strong men?.
Heteronormativa strukturer i asylprocessen : Dess uttryckssätt och påverkan
ABSTRACTThe aim of this study has been to analyse and understand the effects of heteronormative structures in the Swedish asylum process. Homosexual refugees, seeking asylum in Sweden, is in focus when proceeding an analysis about these social structures and normative phenomena. The main discourse, being handled in this study, is between homosexuality and heterosexuality. However, central findings in this study consists of how different approaches, such as gender based identities as well as sexual preferences and ethnic background, combined is influencing the asylum process and the treatment of the asylum seekers.The analysis is based upon legal material, as well as the guidelines and work ethics of the Migrationsverket, which is being compared with theoretical approaches on heteronormativity and structural hierarchy. To achieve a wider understanding of the area and to gain more information, we have also performed interviews with relevant sources.Key-words: Heteronormativity, asylum seekers, homosexuality, power structuresSara Haugbak & Jenny Thomsen, Sociology C, University of Växjö, Sweden.
Likvärdig utbildning för alla barn? En studie om boendesegregation och diskriminering i Sveriges grundskolesystem
The major focus in this study is structural inequalities in primary school in Sweden. UNESCO points out that in many developing countries, up to 40% of the children perform at or below the lowest proficiency level in language and mathematics. Sweden has been criticized by the UN about the large differences in educational achievements between different regions. Based on an official study Sweden considers that those differences are related to ethnically segregate residential areas. My research question is whether the Swedish government takes adequate consideration of the impact that socioeconomically aspects have on educational achievement.
Adaptiv katalysatormodell för reglering
This master?s thesis describes the development of a model of the catalystsystem aiming at control by an MPC. A well functioning model, which is suitable in control purpose, is important while emission legislation become more and more hard to fulfill for the car manufacturers. Much research has been done in the field of physical modeling of the system, but in this work a linear adaptive time discrete ARX-model is developed and validated.The systems tendency to change its dynamic during usage implies that the model must be adaptive. The developed model proved to be well functioning and shows promising conditions for the MPC design.

Automatisk plastlisthanterare
Today a lot of goods is transported on wood pallets because it?s practical and enabels a fast way to load cargo. The drawbacks with pallets are that they weight a lot, are big and are relatively expensive. Therefore IKEA has developed plastic lists that can replace the europallet in some applications. In this examwork an automatic handling equipment for plastic lists are design from a requirement specification to a finished machine.
EU:s tjänstedirektiv - ursprungsprincipen eller destinationsprincipen?
The Vaxholm conflict was initiated when the Swedish Trade Union for Construction Workers shut down a construction site in order to prevent a Latvian construction company to build a school after the two parties had failed to agree upon a collective agreement in compliance with Swedish regulations. An emotional public debate followed that resulted in a discussion of the proposal for the Services Directive of the EU, based upon the country-of-origin principle. In this thesis we will analyze whether the country-of-origin principle or the country-of-destination principle is best suited to capture the gains-of-trade that the common market hoards and improve welfare within the EU. We conclude that the country-of-origin principle is the more apt of the two, though it leads to some short-run costs such as structural unemployment. But these will be more than outweighed by the gains in aggregate welfare for the EU in the long run..
Kravhantering med hjälp av Use Case
Detta examensarbete ger en introduktion till området systemutveckling. Kravhantering har i alla tider varit en viktig del i systemutveckling. För att kunna lyckas med kravhanteringen under ett systemutvecklingsprojekt är det viktigt att använda sig av rätt teknik. En teknik som finns för att kunna hantera de krav som ställs på ett system är Use Case som härstammar från UML. Syftet med detta examensarbete var att ta reda på de för och nackdelar som har upplevts av användare som har arbetat med Use Case i samband med kravhantering.

Ekologisk gestaltning : en utvärdering av hur landskapsarkitektur påverkas av ett ekologiskt förhållningssätt
This paper examines and compares several different sites in Sweden in addition to one in Mexico regarding whether the ecological requirements theses sites have had during planning and construction has affected the design in any way. Is it possible that, for different reasons, one thinks ?like nature? when one thinks of ecology and, if true, how does this reflect on the spatial and structural design? This paper tries to identify if some sort of general design expression is used in projects with requirements on ecological sustainability. In total, five projects have been compared in different areas such as choice of materials and their composition.
These projects have an ecologically sustainable processing of water in common, although most also have ecological consideration in other areas as well.
Orsaker och sammanhang kring avvikelser i processen med prefabricerat byggande
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
