Turkiet : Att vara eller att inte vara - Medlem av den Europeiska Unionen
This thesis aims at studying the European Union?s actions against applicant states. In this case Turkey has been chosen as a variable, because of its unique applying accession.Turkey is a country which has been applying for a membership of the European Union since 1989 and Turkey is the only state which has been searching for membership for more than twenty years. Turkey has been given a lot of critic of not fulfilling the political criteria of the Copenhagen criteria?s.
Implementation av ett interface till Emotiv Epoc
The eld of Brain-computer interfaces (BCI) concerns linking together an external device with the brain of a human or an animal. By doing this the conventional use of a mouse or keyboard can be circumvented, which can greatly benefit people with different types of diseases that cause paralysis or other loss of motor control, such as Amyotrophic lateral sclerosis (ALS). A BCI can also be used for cognitive training of either healthy or mentally impaired subjects to increase cognitive capabilities.In this thesis an implementation of an interface is made against such a device, the Emotiv EPOC Headset. The result is meant to be a stable basis for further study using the device. An in-depth study of the history of EEG and its current use in clinical work and research in the topics of BCI as well as Human-computer interaction (HCI) is presented.
Styrr?ntans olika effekt p? bostadsmarknaden - En komparativ studie om hur bostadspriserna p?verkas olika av r?ntef?r?ndringar i stora och sm? st?der.
This quantitative study aims to investigate whether there is a difference in the effect of the policy rate on the price per square meter for condominiums between small and large cities in Sweden. The study encompasses a total of seven Swedish municipalities, of which three located in large cities and four in small cities. Data regarding housing sales and additional variables have been collected for all municipalities, and the price per square meter is the dependent variable in the regressions performed on the dataset, which constitutes the empirical basis of the study. The aim is further to contribute to an increased understanding of how the effect of the policy rate might differ between Swedish cities and why. The results of the study show significant differences in how the policy rate affects the price per square meter in a small city compared to a large city, with the effect being greater in the latter.
Anställningsotrygghetens effekt på självskattad hälsa, i hög respektive lågkonjunktur
The subject of this study was to research whether or not the effect of job insecurity on self reported health differs between good and bad times in the economic climate. Two different years of a national health survey from the Swedish institute of health (FHI) served as data, with 2007 representing good economic climate and 2009 doing the opposite. Both years consisted of data from a national health survey distributed to 20 000 random individuals in Sweden, where 2007 had 5738 valid cases and 2009 had 10 373. A quantitative method was used to determine the difference, consisting of a three variable cross tabulation with chi2-analysis as well as a model of binary logistic regression for each of the two years.The cross tabulation found a significant difference between the two years, with those reporting job insecurity having less of a chance to report bad health during the year representing bad economic climate. While the logistic regression showed the same tendency, the two years could not be significantly differed from each other in that part of the analyzes.With this in mind, the conclusion from the whole test was that no significant difference could be found between the years regarding the health effect of job insecurity..
EU:s kamp mot terrorismen : Ett hot mot dess egna värdegrunder?
The aim of this study is through a policy analysis to illuminate the decisions that the EU has taken to respond to the terrorist attacks in the US, Madrid and London and through this analysis try to explain the problem of each decision and find out if these decisions might risk the individual rights of the European Union?s citizens.In order to reach this purpose the following questions are to be answered: In what way has the EU?s decision-making process, regarding its fight on terrorism, been affected by the terrorist attacks in Madrid and London? What consequences may the EU?s decisions against terrorism have on the individual rights?The method that has been used is qualitative studies of literature and the main material is overarching policy documents from the EU.The conclusions are that the bombings in Madrid and London have increased the speed of the decision-making process and more areas have been included in the union?s fight against terrorism. If individual rights are at risk by the union?s decisions there are reasons to be concerned. But my conclusion is that the European Union has to have strong and effective instruments to answer to the threat of terrorism..
Distribuerad kognition i cockpit Nu och Då
Denna studie replikerar Hutchins studie 1995 ?How a cockpit remember its speed?, för att undersöka skillnader och likheter i dagens cockpits.Syftet med studien är att ta reda på ifall dagens cockpit distribuerar kognitionen på samma sätt som förr det vill säga används till exempel fartbuggar och andra artefakter på liknande sätt. Samt att ta reda på om det har ändrats mycket hur detta då påverkar cockpit kommer ihåg hastighet inför landning.För att få reda på detta så har observationer gjorts i cockpit under landning. Sammanlagt så observerades sex landningar. Under dessa observationer intervjuades också piloterna om hur de hade beskrivit cockpits minne av hastigheter.Resultatet i studien visar att det finns mycket som fortfarande fungerar på liknande sätt som tidigare.
De tre vise männen - En fallstudie av Kinas övergångsperiod
When Deng Xiaoping introduced his reform program, he began China's transition from a plan economy to a socialist market economy. Liberal theorists often argue that there is an automatic link between ?free market? and ?democracy?, however this link is not evident in China. This contradiction constitutes the problem area of this thesis.With a theoretical framework containing ?totalitarism? and ?Tang Tsous culturalist approach? I have analysed the leadership of CCP (China's Communist Party) and its strategies to maintain the Chinese political system.
Vitamin C? som i Choklad?: En studie av inkongruenta varumärkesutvidgningars inverkan på produktkategorin
The purpose of the study is to explain whether the introduction of a new and different brand by means of a brand extension affects consumers? perceptions of the product category that the brand is launched in. An experiment was carried out to study the following aspects: associations and constellations of associations to the product category, interest, perceived variation, and the perceived similarity with the category from which the brands were extended. In the study, brand breadth in the original product category was used as moderating variable. Aspects found to be affected by the brand extensions were associations to the product category, the constellations of these associations and the perceived similarity with the category from which the brands were extended.
Measurement technique for high speed flywheel
Örebro svets & hydraulik AB tillverkar lastknektar till Suzuki Garphyttan. På lastknektarna transporteras sedan stora rullar av tråd i stål. Knektarna har visat sig kollapsa efter viss tids användning och behöver därför en förbättrad konstruktion. Höga laster, tuff hantering samt ovarsamma lyft kan vara orsaker till att knektarna kollapsar. Örebro svets är väl införstådda var skadorna uppstår i nuvarande konstruktion och vill därför förstärka denna del och konstruktionen i sin helhet.Kraven på den nya konstruktionen, förutom att vara mer hållbar, är att befintligt mått mellan benen ska följas och att knekten ska vara staplingsbar vid transport till galvanisering.Nuvarande knektar har modellerats i CAD-programmet Pro/ENGINEER för att sedan analyseras med Finita Elementmetoden i beräkningsprogrammet ANSYS för att visa var deformation och spänningar uppstår.
L?gkonjukturens p?verkan inom byggf?retag
The purpose of this study was to gain a better understanding of how medium-sized construction companies adapt and how they choose to reorganize their operations in relation to the recession. The study has as its theoretical starting point theories about organizational learning, the impact of the economy on construction companies and strategies for dealing with recessions. The
method used to conduct the study was semi-structured interviews with representatives from 15 different construction companies. The results of the study show that they used several strategies to adapt and reorganize the business in accordance with the recession. Some construction companies had to make cost savings as a result of the recession.
Projektuppföljning - En studie av relationen mellan projektuppföljning och organisationsstruktur
This paper aims to examine performance monitoring in project organisations. The number of organisations that regularly performs projects as a key part of their operations grows rapidly, why this topic has become of large interest. Through a theoretical framework developed by Lars Östman in 1977, the performance monitoring system of the Swedish government-owned public utility Svenska Kraftnät is studied closely. The results from this analysis are then linked to an analysis of the organisation's internal structure through Mintzbergs generic organisational structures. Close connections are found between organisational structure and performance monitoring, which leads on to interesting observations about the connection between size of a project organisation and choice of monitoring method..
Sambandet mellan hästens huvud/halsposition och ryttarens rörelse i sadeln :
Dressage schooling is not a subject that rests on science, it is a matter of dependable experience. So far there hasn?t been so much research about it, but more and more is done. Especially the interaction between rider and horse is a nearly uninvestigated field. Riding skills is much about having the right position, and having the horses head and neck in different positions, but there are no research done that support or deny that this old ?knowledge? is for the best for the horse.
This study was performed to evaluate if the head and neck position of the horse, and the velocity, has any influence on the position of the rider.
Making Money in a Dirty Business
Academic research concerning how to determine the power situation in a supply chain where an investment product supplier is involved did not exist. Therefore new models has been developed that analyses the power relations and maps out the power situation in a supply chain. In the future these models can be applied on similar cases by modifying the included parameters. The new models show that case company FAS should focus on the big producers of garbage bag which are Trioplast, Rullpack and Miljösäck. By strengthen the brand FAS can make more money in these relations.

GPU accelerated SPH simulation of fluids for VFX
Fluids are important to the Visual Effects Industry but extremely hard to control and simulate because of the complexity of the governing equations. Fluid solvers can be divided into two categories, those of the Eulerian point of reference and those of the Lagrangian. Both categories have different advantages and weaknesses and hybrid methods are popular. This thesis examines Smoothed Particle Hydrodynamics, a Lagrangian method for physically based uid simulations. To allow the artist the exibility given by shorter simulation times and increased number of iterations, the performance of the solver is key.
