A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.

TitleSystems, Stability and Power. The Discourse of Information in Organizing Knowledge.AbstractThe aim of this Master's thesis is to inquire into the consequences of an unequal distribution of power between information discourses in the field of knowledge organisation. A deconstruction of Jennifer Rowley's and John Farrows introductory textbook Organizing Knowledge from 2000 is related to the major discourses of information in LIS. Questions posed in this study are: What meaning is ascribed to information in the material studied? Which information discourses are given a dominant position? Which are excluded? and: How does this affect the construction of the library and information science student's identity, in relation to practices of knowledge organisation? The theoretical framework is provided by Ernesto Laclau's and Chantal Mouffe's theory of discourse and combined with techniques for text analysis originating from the work of Norman Fairclough.The analysis reveals a strong domination of a cognitive discourse of information that underlines the importance of information systems for the organisation of knowledge.

Denna rapport beskriver arbetet med utvecklingen av en ny modell för kaplanturbiner. Utvecklingen bygger på två kopplade differentialekvationer som under arbetets gång anpassats och implementerats i turbinmodellen.Modellen beskriver hur vattenflöde och turbinmoment påverkas av avvikelsen från den optimala kombineringskurvan för vinklarna på turbinens ledskena och löphjul, och är anpassad för ett referensaggregat med tillgängliga provdata. Även övriga enheter i vattenkraftaggregatet modelleras och sätts samman med frekvensregulator och elnät för att simulera aggregatets reglerstabilitet i önätsdrift.Verifieringen av turbinmodellen sker genom försök att återskapa de befintliga verkningsgradskurvorna med hjälp av modellen. Resultatet visar en god följning av de verkliga kurvformerna, dock med något lägre maximal verkningsgrad.Verifieringen av önätmodellen sker genom att prova stabiliteten i nätfrekvens och turbineffekt vid stegpålastningar. Resultatet ger en stabilare reglerstabilitet än i verkligheten, men uppfyller ändå förväntningarna på en fungerande modell.This report describes the development of a new kaplan turbine model.

In this thesis proposals for different designs of a borehole thermal energy storage (BTES) have been developed for the building DN-huset in Stockholm, Sweden. To build a BTES results in savings in energy costs by approximately 44 %, i.e. 2 million Swedish crowns annually. Furthermore, a BTES would reduce the annual environmental impact with roughly 75-157 tonnes of CO2 equivalents per year, depending on how the electricity consumption?s environmental impact is estimated.

This study was conducted in the Master program at The Music Pedagogical Center (MPC) at The Royal College of Music in Stockholm. Korta musikresor (Short Music Journeys) is the Swedish term used for a receptive method of music therapy adapted from the tradition of The Bonny Method of Guided Imagery and Music (BMGIM) and the theory and practice of Expressive Arts Therapy. The KMR method uses carefully selected short pieces of music, lasting between 2 and 5 minutes, to work on various psychological problems and life- crises. The music session is conducted in a slightly altered state of consciousness with a clear focus being established beforehand in a verbal dialogue with the psychotherapist. There is also the possibility of using artwork to process and explore the imagery after the music listening.

In industrial control systems PID-control remains the prevalent strategy, also for processes that would benefit from model based control. The purpose of this thesis is to evaluate whether model based control can be readily implemented in an industrial control system. To this end a simulated surge tank with a simulated industrial control system is studied. For evaluation two scenarios with specified objectives are selected.Following a review of LQR and versions of MPC, Predictive Functional Control (PFC) is considered the most suitable for implementation. PFC is a form of MPC developed with industrial applications in mind and therefore has several advantages for implementation in an industrial control system.

Purpose ? The purpose of this thesis is to develop a total cost model for container transports and create a tool that calculates a suitable transport quantity from an economic view, which fulfills the demands on delivery service. To achieve this purpose the following questions will be answered:Which costs are affected by the decision between the two transport alternatives LCL and FCL?   How does the decision of sending product LCL or FCL influence the delivery service?  How can a tool be constructed to simplify the decision-making process regarding the choice of sending products LCL or FCL?  Method ? A total cost model was developed. This model is supported from existing literature.

Inom byggbranschen uppstår dagligen fel och problem. Tidigare studier har visat att kostnaderna för att åtgärda dessa uppgår i genomsnitt till 4,4 % av produktionskostnaden. Dessa felkostnader är endast de som upptäcks under produktionsfasen. Ska man även räkna in de som upptäcks och åtgärdas under brukstiden kan siffran uppgå till hela 10 % av produktionskostnaden.Syftet med detta examensarbete var att få större förståelse för varför fel uppstår i byggprocessen och vad som ligger till grund till dessa, samt ta reda på vilka nya metoder det finns inom planering och projektering. Arbetet har skett i samarbete med Peab Karlstad och innefattade undersökningar av tre olika byggprojekt.

The aim of this study was to map and date glacial flutings with ice flows deviating from the predominating northwesterly ice flow direction in the southern part of Norrbotten County in northern Sweden, and also to investigate if parts of the glacial landscape are older than previously thought. The traditional view is that most landforms in the area were formed during the late Weichselian (W3). Analysis of the new high resolution elevation model (2 m grid) derived from laser scanning was performed after treating the data with a hillshade tool in ArcMap to reveal terrain features such as flutings. The analysis resulted in a map showing four main groups of deviating ice flows (N-S, NO-SV, SO-NV and S-N) and several westerly ice flows. The majority of flutings with deviating ice flows were found in low terrain.

This paper aims to explore the possibility of reading the Temple cleansing stories of John and Mark through Bruce J Malina?s honor/shame model, as E. Randolph Richards do. The analysis searches in John?s and Mark?s Temple cleansings for the presence of the notions of honor and shame, as Malina uses those concepts in his model.

The interest in building low energy houses has increased along with the rising engagement inthe climate questions. With the advancing energy prices it is highly suitably for those whobuild and administer their buildings in long-term to build energy-saving houses. 40 % ofSweden?s total energy consumption constitutes of the energy in residences, therefore it iscrucial to take advantage of all the free energy as we possibly can. With crucial questions likequality of living and profit low energy building is a subject that concerns us all.Three proposals for apartment blocks are presented in this work on a real estate in Stockholm.Each proposal is developed through unique processes of design with the purpose to displaypossibilities to deal with the energy requirements of today and tomorrow through energybased architecture.The first proposal is an apartment block based on a traditional design process, the demands ofthe property owner and it?s affected by opinions from architects.

The most predominant method for forest harvesting in Sweden is the cut-to-length method based on two-machines, a harvester that fells trees and cut them in a predefined length, and a forwarder which transports logs to a landing area for further transport to a processing facility. New machine solutions have to be much gentler to the ground than today?s machines. To be able to develop a forestry machine that preserves the terrain requires a proper understanding of the interaction between tire and soil.The goal of the project is to contribute to the existing knowledge of forest machine tire-soil interaction and to develop a tire-soil model that enables dynamic simulations of forest machines operating in rough terrain. The modeling has especially been focused on the interaction between tires and soft ground.A comparison of theoretical data of different WES-based terrain interaction models and a comparison test data from a full scale field test is presented.

I have examined acclimatization models in pre-school. My emphasis is on the shorter acclimatization models. To begin pre-school is a big change, not only for small children, for the whole family as well. It is important to get a good acclimatization in pre-school, and one of the things it takes to achieve that is to interact with the parents. The reason why I chose this subject was because we have not studied much literature about this subject during our education to become pre-school teachers.
