Spinn-off på Stockholmsbörsen : En eventstudie om hur moderbolagets aktiekurs reagerar vid nyheten om spinn-off
Problem Are there any abnormal changes in the parent company's share price at the news of a spin?off.ObjectiveThe main purpose of the study is to investigate how the news of a spin-off affects the parent company's share price. In other words if the news of the Spin-off gives an abnormal return on the Stockholm Stock Exchange during the specific period of 1998?2008. In addressing this, the paper will also investigate the following sub sections: are there any differences in the abnormal returns in various sectors and what the reasons to perform a spin?off in the Swedish market are.MethodAn event study in which market data is used to measure specific events? impact on the value of the company and on the effects on the stock market.
Analys, modellering och återskapande av fordonsdynamiska rörelser i tåg
The purpose of this thesis was to analyse, model and finally generate dynamic vehicular motions in a train. The objective with the analysis was to find important motions for a realistic train experience. The motions from the analysis were then weighted against possibilities for generation in a motion platform.A dynamic motion model was created to model the selected motions. The model was implemented in a simulation environment, more specifically MATLAB/Simulink. The simulation environment was used to simulate the model and to generate outputs to control a motion platform.
Ett krig - tre sidor : En kritisk diskursanalys av Irakkriget i brittiska, svenska och amerikanska medier
Will the discourse in a country effect the way an event is presented in the media? And will the event be presented in similar ways in different countries? These are the questions my paper aims to answer. By using critical discourse analysis I have analyzed the reporting of the Iraqi War in three big newspapers; one from USA, one from Sweden and one from Great Britain. The results show that the discourse in each country play a big part in how the news get presented in the media, and this is shown in how the news gets reported. The three countries had three different views on the same war.
Har mega-event utvecklats? : En innehållsanalys om hur hållbarhetsrapportering har utvecklats över tid i mega-event
Begreppet hållbarhet definieras som ?en utveckling som tillfredställer dagens behov utan att äventyra kommande generations möjligheter att tillfredställa sina behov?. Inom företagsvärlden blir det allt mer vanligt att hållbarhetsrapportera vilket även organisationer tagit efter. Mycket forskning har bedrivits inom hållbarhetsormrådet, dock har författarna sett att det saknas forskning kring hur mega-event ställer sig till begreppet. Detta resonemang har lett författarna till följande problemformulering: Hur har utvecklingen av hållbarhetsrapportering sett ut över tid i mega-event? Studiens teoretiska ramverk inleds med en historisk utveckling av CSR från 1950-talet fram tills idag samt hur det används i mega-event.
Brand i förorten : En studie av etiken i journalistiken
A great fire seized a suburb in a small town in Sweden in the autumn of 2011. Parts of a shopping mall were burnt to the ground by youngsters. Due to the suburb's earlier problems, the event was a tough ethical dilemma for the town's journalists.The purpose of this thesis was to study and examine the local newspapers ethical treatment of this event. How do they motivate their decisions on what to publish and what not to publish? How do the articles treat ethical dilemmas? What do the journalists think about ethical journalism?This study is based on a survey of the articles published about the fire in the two local newspapers seven days after the fire.
Aktiva trasdockor med samverkande kontrollsystem i dataspel
Animation av karaktärer är en viktig del inom dataspel. Den interaktiva, oförutsägbara naturen av spel kräver att karaktärer måste kunna reagera dynamiskt på händelser i miljön för att upplevas som realistiska. För att göra detta möjligt räcker det inte att använda tekniker baserade på förinspelad animationsdata eller fysisk simulation av karaktärer i medvetslöst tillstånd.Ett system som kombinerar kontinuerlig fysisk simulation av karaktärer med ett kontrollsystem baserat på förinspelad animation åstadkommer fysiskt korrekta rörelser hos en karaktär. Genom att utöka ett sådant system med introducerandet av möjligheten för flera samtidigt samverkande kontrollsystem, baserade på dynamiska såväl som förinspelade tekniker, i ett uniformt interface kan en karaktärs rörelser modulariseras. Detta tillåter sammanställandet av en ?verktygslåda? av rörelser.En sådan uniform verktygslåda, kombinerad med en kontrollerande artificiell intelligens, gör det möjligt att utveckla fullt självständiga virtuella karaktärer i en dynamisk miljö..
read me. do you copy ? - en undersökning av litterär interaktionsdesign i utställningsrummet
We are heading for a line, and its a fine one. This project is a dialogue between you and I; about the dialogue itself. The initial interest was to use literary text to address the visitor in the exhibition space. The purpose was to make man aware of its relation to others and narrative objects. I planned for the dialectical event in every descision.
Företagsförvärvs inverkan på den kortsiktiga avkastningen : En eventstudie om kursutvecklingen vid offentliggörandet av ett förvärv
Purpose: The main objective of this study is to research whether an announcement of an acquisition generates positive/negative abnormal short-term return towards the buying company?s shareholders. The secondary purpose is to research whether any differences could be due to selected factors: firm size and industry.Method: The study is quantitative in nature where the research aims at the stock price movement around the announcement of an acquisition. The sample size includes 30 companies between the years 2000-2010. The abnormal return is investigated by an Event Study.Conclusion: Our study shows that the publication gives a positive abnormal return in comparison to the respective sector indexes.
Visualization of Particle In Cell Simulations
A numerical simulation case involving space plasma and the evolution of instabilities that generates very fast electrons, i.e. approximately at half of the speed of light, is used as a test bed for scientific visualisation techniques. A visualisation system was developed to provide interactive real-time animation and visualisation of the simulation results. The work focuses on two themes and the integration of them. The first theme is the storage and management of the large data sets produced.
Standardisering av brukarrelaterade indata för energiberäkningar på kommersiella lokaler
In this thesis, input data for energy performance calculations on commercialpremises have been studied. In energy performance calculations, where internal heat gain parameters are unknown, template values that, in a reasonable way represent the activity in the room, are necessary. These values can be used as input data for whole-year calculations, or for calculations on shorter periods of time.The purpose of the Sveby project is to create standardized work practice in energy issues for the construction industry. The work in this thesis is conducted to correlate with the purpose of the Sveby project, with aims of contributing with information and guidelines for the continuing work with commercial premises.In this report, suggestions for template values for internal gains parameters, based on research and calculations in the field are presented. Suggestions on how these can be implemented in a user-friendly way for two energy performance calculation software are also given, VIP Energy and IDA ICE.
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.
Eventstudie av reporäntans effekt på aktiemarknaden
För alla intressenter på aktiemarknaden är det av stor vikt att fastställa hur olika faktorer påverkar börskurserna. Styrräntan är en sådan tänkbar faktor och mycket forskning har skett angående dennes påverkan på aktiemarknaden, främst på den amerikanska marknaden. De tidigare amerikanska studierna av eventuella samband mellan förändringar av styrräntan och aktiemarknaden har kommit till slutsatsen att sambandet existerar samt att det är av negativ karaktär. När höjningar av styrräntan har utannonserats har man sett en sänkning av aktiekurserna och vise versa.Denna uppsats undersöker genom en event studie om det finns något samband mellan reporänteförändringar och börskurser på den svenska marknaden. Fyra branschindex från Stockholmsbörsen har används och studien gäller samtliga reporänteförändringar mellan januari 2004 till oktober 2008.
Kombinerat system för ventilation och rumsuppvärmning : Parameterundersökning i simuleringsmodell för takvärmesystem
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.
Abnorm avkastning för konkurrenter till budmottagande företag - En empirisk studie av företag listade på Nasdaq OMX Nordic
This paper aims to investigate abnormal returns for rivals to bidder targets in connection with the announcement of the bid. The study is based on 38 bids placed between September 2006 - January 2011 and 137 rival firms listed on Nasdaq OMX Nordic. We measure cumulative abnormal returns, CAR, for rival firms through an event study. We find that rival firms earn significant positive CAR in connection with the announcement of the bid. This is in line with the two-sided signaling effect presented by Akhigbe et al.
