Diffusion MRI is an imaging technique capable of inferring information about the tissue microstructure, based on magnetic resonance imaging (MRI). Diffusion MRI data can be analysed using tractography, a tool able to represent the structure of the white matter (WM) in the brain. Tractography is commonly used qualitatively, but in this report, an algorithm for quantitative tractography was develope
Diffusion tensor magnetic resonance imaging (DT-MRI or DTI) is an imaging technique that is sensitive to the diffusion movement of water contained in tissue. It is used to quantify parameters such as the diffusivity and its directionality. Because diffusion is intimately connected to the tissue microarchitecture DTI is one of the few techniques that can quantify tissue microstructure non-invasivel
Breast tomosynthesis (BT) is a new X-ray modality that reconstructs the breast volume in many slices instead of, as in mammography, showing a single 2D projection of the breast. The slice thickness is typically 1 mm for clinically used BT-units. In screening the review of breast images with BT takes two to four times longer than the review of mammography images. In an effort to reduce the review t
Introduction: Arterial spin labelling (ASL) is a non-invasive magnetic resonance imaging (MRI) technique for assessment of perfusion. ASL uses magnetically labelled blood water as a diffusible endogenous tracer to measure the perfusion of brain tissue, i.e. the cerebral blood flow (CBF). Traditionally, ASL samples images at a specific point in time allowing the CBF to be calculated using a model o
The purpose is to investigate whether the correlation between equity returns and changes in CDS spreads is stronger for sub-investment grade companies than for investment grade companies in the European iTraxx indices.
The thesis is an attempt to investigate the use of “informal justice as a political method” ( or “IRPM” in short) by the two Swedish right-wing organizations “info14/Fria Nationalister” and “Svenska motståndsrörelsen” using the organizations’ own web-published material for the period of 2000-2009, and to put the organizations’ use of “IRPM” into a Swedish empirical context. The thesis goes about
Near Field Communication (NFC) is a form of wireless communication technology enabling data transfer by putting two devices close to each other. The main idea behind NFC is to integrate wireless payment and tag reading in mobile phones along with peer-to-peer communication. An example of the benefit with NFC peer-to-peer communication is that it gives the possibility to quickly set up a Bluetooth
The Single Molecule Spectroscopy Group at the department of Chemical Physics in the Chemical Centre of Lund University conducts research involving spectroscopy on single molecules of organic dyes. Fluorescence microscopy using a wide-field scheme has been used and such a scheme has many advantages such as full image capture at once when using a high sensitivity CCD or CMOS camera. Using different
An engineer always strive to help in the continuous exploration of the unknown. By doing so we go further out in space and further down in scale. This is the case with microfluidics which in the last years have gotten a lot of attention. This thesis will examine and better try to understand and optimize a fluidic system that uses ultrasonic trapping. Its application may be everything from enrichin
In this Master's thesis I present a means of finding active sources of cortical electrical activity from electroencephalogram (EEG) data acquired during operation of a brain-computer interface (BCI). A novel subspace-based technique was used to suppress spatially correlated EEG interference sources, followed by a technique that estimates the source parameters with a near maximum likelihood per
This thesis, issued by Securitas Direct, investigates the possibility of using acoustic emission as a basis for an intrusion alarm application. Piezoelectric elements were used to detect and characterize fractures in glass, metal and wooden materials. As a comparative study, the functionality and possibilities of using an existing glass break detector, GlassAlertTM, on wooden materials were invest
This essay examines the implicit relationship between political science and rare events, or so called Black Swans. The purpose is to analyze Black Swan weakness by evaluating the nature of political analysis and political theories. The key to this assessment is the analysis of the predictive powers of political analysis and theories. This essay claims, on the basis of Karl Poppers historicism crit
During the devastating civil wars in Liberia and Sierra Leone women’s organizations played an important role for the emergence of peace, and are still influential in the building of equal and democratic societies. In Liberia, however, the women’s movement was more successful in influencing and affecting the warring parties for peace and gender equality and the purpose of this thesis is to outline
This thesis aims to develop a theory on the role of water in an intrastate peacebuilding process, which is an area of research that has not yet been explored. The notion presented and which drives the following argumentation is that water with its practical, essential, local and cooperative characteristics could be an important factor in a peacebuilding context. The theoretical discussions take as
Giant Unilamellar Vesicles (GUV) have the potential to play a dominating role in future scientific efforts to understand and model biological systems through the creation of artificial cells. GUV:s span a wide range of possible applications that include their use as biosensors, cell encapsulation agents and biomicroreactors. In order to allow GUV:s to reach their full potential, efficient, reliabl
̊r 1947 utbröt den så kallade Kashmirkonflikten och det har sedan dess varit mycket oroligheter mellan Indien och Pakistan om vem som har rätt till Kashmirområdet. Denna avhandling syftar till att förklara vilka faktorer som har bidragit till Kashmirkonfliktens uppkomst samt analysera hur dessa faktorer påverkat konfliktens utbrott . Det görs genom att analysera både internationella och inhemska f
This study is about citizen participation in regional visionary development and focuses on what makes the democratic system legitimate. The primary purpose of the study is to evaluate the regional visionary plan in aspect to normative ideas about democracy. This democratic norm is borrowed from K. Sjövik and focuses on citizen participation in all aspects of democracy. The primary material for thi
Since the mid 90s more focus has been put on the problems surrounding hooliganism, especially in the media. This began when football referee Anders Frisk was injured during a football game. Nowadays, the police use more and more resources to prevent the problems with hooliganism and new laws have been instituted to handle the problem. More and more politicians, football players, coaches, and club
Through discourse analysis I investigate how the Swedish liberal party, Folkpartiet, constructs two opposing identities in their discourse of alienation (in Swedish utanförskap). I draw from Torben Bech Dyrbergs theory on how identities are constructed through the logics of difference and equivalence (1997). Laclau and Mouffe are the main inspirations for analyzing the organization of the discours
