This paper is an assessment of whether the Nordic countries constitute an optimum currency area (OCA) or not. Hodrick Prescott-­?filtered data of real Gross Domestic Product (GDP) and rate of employment are used to investigate the similarity of business cycles between the target countries through a series of correlation analysis with Sweden as the base reference country and also by using a linear regression model. Additionally there is an evaluation of trade volume and labour mobility between the countries. Our results indicate that Iceland had the least similar business cycles within the Nordic countries and that the area should therefore possibly comprise Denmark, Finland, Norway and Sweden. .

The amount of information stored on the internet grows daily and naturally the requirements on the systems used to search for and analyse information increases. As a part in meeting the raised requirements this study investigates if it is possible for a automatised text analysis system to distinguish certain groups and categories of words in a text, and more specifically investigate if it is possible to distinguish words with a high information value from words with a low information value. This is important to enable optimizations of systems for global surveillance and information retrieval. The study is carried out using word spaces, which are often used in text analysis to model language. The distributional character of certain categories of words is examined by studying the intrinsic dimensionality of the space, locally around different words.

Learning Management Systems (LMSs) hold great potential to support learning activities, for example by providing teachers and students with new and extended spaces for interaction and collaboration. However, this potential appears to be difficult to realize, and despite their perceived learning benefits, the reality is that LMSs are being used primarily for administrative purposes. Meanwhile, external pedagogical tools are successfully put into practice to improve learning outcomes, and the aim of this study is therefore to identify and discuss benefits and disadvantages associated with the LMS as a concept. By interviewing secondary school teachers, we disentangle the idea of integrating administrative and pedagogical aids into a single platform, providing detailed insight into the use of digital tools in secondary education. The study contributes to a deepened understanding of integrated learning environments, and we conclude that there is a conflict between structure and flexibility that needs to be addressed before determining the design of a digital learning space..

Today?s media consumption and viewing behavior has led to an expansion in the marketand resulted in a media convergence. The competition gets fiercer with each player andthe outcome for the linear TV channels has to be to change in some way. This is aqualitative interview study with producers at Sweden?s leading children channel?Barnkanalen?, how they experience the adoption to this new media landscape.

In this master thesis work, a new method called MultiScat, is compared with the conventional method with alfa-correction, for computing concentrations from intensities in X-ray spectrometric analysis. The conventional model is a linear model, which only takes the photoelectric effect into consideration. It doesn't consider Rayleigh and Compton scattering even though it has a great impact on the measured intensities. Here MultiScat differs a lot. MultiScat is based on a solution of the Boltzmann transport equation.

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

When one experiences a place, it is a complex composition of both social and spatial factors.One of these spatial elements, is scale, which is influenced both by the room size and itsproportions. This paper aims to explore both large and small scale concepts and thus increasethe understanding of how scale directly and indirectly affects the experiences and uses ofurban space.First, is a theoretical discussion of scale in relation to aesthetics and the differencesbetween real scale and perceived scale. Next, is an analysis of spatial perception usingexamples from two existing sites. One, which is understood to have been planned in a largescale and one which is understood to have been planned in a small scale.When preparing this paper, the focus quickly became the importance of scale as itrelates to street spaces. The perception of a street usually takes place while in motion, whichforces it to be perceived in sections.

The aim of this study is to investigate the needs and wishes of 10-13- year old children, so called tweens, when it comes to their local library. What kind of library do the children want? How does the mission and different functions for the children's library of today correspond to the needs of the children? Children of this certain age have been interviewed in focus groups where they have had freedom to ?create? their own library and discuss what they consider important in a library. Skot- Hansen, Rasmussen & Jochumsen's model (2011) with four important spaces for a library - performative space, learning space, inspiration space and meeting space has been part of analyzing the result. These four different areas for the library have been divided into threefunctions: a place for being, a place for learning and a place for creating.The result of the thesis shows, among others, that even though many of the aims of the libraries and the results of research correspond to the ideas and needs of the children, one of the most important functions for the children is the library as a place to relax, a quiet room, where they can dive into their books and other media, which has not been discussed in the research I have taken part of.

This report aims to study the condominium prices in central Stockholm and the factors thataffect these prices. A linear regression model was set up and data about relevant covariatessuch as floor area, mortgage rates and where the condominium is situated were gathered toassess if and how they influence the price. The raw data was processed and enhanced to gain asmuch relevant information as possible to the model. To determine the covariates? influence onthe final price, regressions were ran and various tests were performed on the output data.

A study of paleomagnetic remanence and anisotropy of magnetic susceptibility (AMS) has been performed on the Öje-Diabase in Dalarna, Sweden, and on basic dikes associated with the alkaliquartzsyenite/granite Noran-pluton in central Sweden. Based on isolation of directions of characteristic magnetization in the basic rocks, a division into three different groups (A,B,C) has been made. Group Aconsists of dolerites of Jotnian origin, both dolerites from the Öje-Diabase and dikes associated with the Noran-pluton are included in this group, making them coeval. Group B is suspected to show a re-magnetization from the later part of the Svekonorwegian orogeny. Group C belongs to the Blekinge-Dalarna-Dolerites (BDD). Thermal demagnetization of dolerites revealed two different types of demagnetization behaviours, one where magnetite clearly was the source of the remanence, and an other with a linear decrease in magnetization intensity. The measurements of magnetic anisotropy reveals a magnetic fabric with an almost horizontal foliation and a lineation that indicates a fairly uniform NNW/ S-SE flow direction of the magma..

The essay is written at the request of Nyköping municipality park management by PatRadestedt who wanted a design proposal for one of the five courtyards at the Tessin Schoolin Nyköping. The Tessin School is located 2 miles from the center of Nyköping and the schoolhouses approximately 900 students. To make a design proposal for the courtyard that lies atthe canteen I decided from the outset that I wanted to take some of the Tessin SchoolStudents' opinions and wishes regarding their own outdoor spaces. I had a workshop witheight students from the arts program with the image orientation in which they had to drawand tell them what they wanted to do in the courtyard. The outcome of the workshop, Iused to move forward in my future work with a concept that fit into the environment, wethen apply it in my final design proposal.

For research purposes Saab has developed a generic mathematical model denoted VEGAS of an aircraft with a configuration similar to JAS 39 Gripen. Today parts of Gripen backup control system are used also for VEGAS making the system subject to both corporate and defense secrecy. The main objective of this master thesis is to design, verify and implement public pitch axis flight control system for VEGAS. Furthermore, simplifications regarding the design process is to be examined. Design of pitch axis flight control system for the entire flight envelope has been carried out.

This thesis aims to open the Pandora?s Box of hedge fund styles through an index-based style analysis. This information asymmetry is due to both less strict disclosure requirements and inherent nature of hedge funds. We employ a multiple unconditional linear regression model wherein 23 Swedish hedge funds are regressed on 10 style indices. In addition to the increased interest in hedge funds and their performance drivers, our unique approach with regressing return on return motivates this study.

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
