An investigation of a potential multipurpose readout modality for two and three-dimensional dosimetry using optical computed tomography scanners

Radiochromic film, polymer gel and radiochromic plastic are three different kinds of dosimeters developed for radiation therapy. Even though all three types of dosimeters are suitable for optical scanning, the proposed readout method is different for each detector system. In this study, the scanning properties of three optical CT scanners were investigated to determine if they could be developed i

Improved analysis of MRI tractography data: Group comparisons of parameters along fibre tracks

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 Imaging in the Cervical Spinal Cord: Implementing methods for acquisition, processing and evaluation

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

Effects of slabbing and slice thickness on image reading time and micro calcification detection in breast tomosynthesis

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

Perfusion MRI: Non-Linear Stochastic Regularization for Deconvolution of Model-Free Arterial Spin Labelling Data

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

Informell rättsskipning som politisk metod

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

What affects related party Transaction? Evidence from Public Listed Companies in China and the U.S.

This study aims to find out the factors that could affect a firm’s RP transactions considering different social situation, extent of economic development and other culture factors. We examine related party transactions of the listed companies in China which stands for the emerging markets and in the U.S. which stands for the developed markets. We expect the conclusion that factors such as firm siz

The MaP of Opportunities- How to Create Value in the Older Machine Segment

MC, Machine Corporation, although historically successful is facing challenges as the industry in which they operate is matured. They thus need to find new ways of generating revenues. The service and parts market penetration rate decreases in the Danish market as the machine ages, but the need of service and parts increase why we argue that there is a market potential not being exploited as of to

Accounting for Gifts: How Consumers Understand Free on the Internet

Purpose: To investigate how consumers understand free services on the Internet. Theories: The research is primarily based upon theories of gift giving. Methodology and analysis: The Internet is not a tangible marketplace and in order to understand the value of the free services online, we used consumers' behavioral accounts to explain how they perceive the free services that are common online.

Sverigefonder - fondorganisatoriska egenskapers påverkan på prestation

Syfte: Det första delsyftet med uppsatsen är att undersöka om fonderna i vårt urval har presterat under en 10 års period. För att mäta prestationen har vi använt oss av Sharpekvoten, Treynorindex samt Jensens Alpha. Huvudsyftet med undersökningen är att undersöka om prestationen sedan kan härledas till fondernas organisatoriska egenskaper. Resultaten ska kunna ge bättre vägledning för privata inve

Importance of legitimacy based on trust in startup ventures

The purpose of this paper is to make a personal reflection of the last year when I have been studying the Master’s Programme in Entrepreneurship at Lund University and the experiences I have had during this time. This paper mainly explores the importance of legitimacy and what you need to do to adapt and maybe change to fit in on a market but also the importance of trust, both within your own orga

Different shades of pink

The purpose of this study is to gain a deeper understanding about the consumption of contemporary charity in Western society on the example of the Swedish breast cancer charity Rosa Bandet. The study reveals exciting nuances of contemporary charity consumption, among them the glamourisation and disarming of cancer, the commercialisation and merchandisation of charitable giving, the changing role o

Riskbedömning - Potentiella klienters risk ur revisorers perspektiv

Sammanfattning: Syfte: Syftet med detta examensarbete är att förklara hur revisorer ser på risk när de bedömer potentiella klienter. Metod: Ett positivistiskt angreppssätt och en deduktiv ansats, med en kvantitativ metod, har använts för att nå fram till resultat för analysen. Teoretiskt perspektiv: Studien utgår ifrån ett eklektiskt teoretiskt angreppssätt och tidigare forskning inom området. Teo

Value for Money Assessment in Public Private Partnership Projects

Public Private Partnership, PPP, is a public procurement method involving the private sector used in several countries all over the world, now upcoming in Sweden. The UK, most prominent within this method, states that it offers good value for money, but the economic and financial benefits of PPP are still uncertain and subjects of debate. In order for the projects to be successful and to achieve v

The Concept of Human Dignity in International Law

As we have evolved, human beings have developed a wide range of disciplines and discourses through which we address, analyse, dissect, explore and seek to progress, various aspects of our lives and what it is to be a human person. When considered from the perspective of each of these individual disciplines or vantage points different human features and aspects become the focus, depending on the le

Do human rights exist without social rights?

This thesis is to introduce the international fora of social human rights, focusing on the social security system of Finland. To demonstrate the complexity of the subject, analyses are made in solidarity, nature of norms and social dialogue. Regardless of the efforts of the International Labour Organization to stabilize social security matters by different Conventions and Covenants, at the nation

Effects of allocation of attention on initial racial face discrimination

Utilizing a modified version of the affect misattribution procedure, event-related brain potentials of 32 Caucasian participants were examined in order to study the effects of allocation of attention on early racial face perception and discrimination. When attention was directed away from faces, towards ambiguous non-face stimuli, larger N1s, peaking at approximately 110 ms after stimulus onset, w
