Chronic diabetic foot ulcers are a source of major concern for both patients and health care systems. Oxygen deficiency plays a major role in the pathogenesis of these ulcers. Hyperbaric oxygen therapy (HBOT) has been proposed as a medical treatment for diabetic foot ulcers, but the clinical utility has not been established. Hyperbaric Oxygen in Diabetic patients with chronic Foot Ulcer (HODFU) st
The aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. Non-steroidal anti-inflammatory drugs (NSAID) are the first treatment of choice. The use of NSAIDs, especiall
Osteoarthritis (OA) is a common chronic disease and one of the major global causes for functional disabilities. The disease is characterized by loss and degradation of cartilage, commonly affecting the knees and hips. Delayed gadolinium-enhanced MRI of cartilage (dGEMRIC) is a previously presented method for identification of early OA using magnetic resonance imaging (MRI). By quantifying the T1 p
Modern spectroscopic techniques, such as nuclear quadrupole resonance (NQR), nuclear magnetic resonance (NMR), and Raman spectroscopy, rely heavily on statistical signal processing systems for decision making and information extraction. The first part of this thesis introduces novel robust algorithms for detection, estimation, and classification of signals obtained through these spectroscopic tech
This dissertation is a study of metaphors of emotion in rebétiko song texts. Rebétiko is a major popular-music style of modern Greece, consisting mostly of melancholic songs full of sorrow, disappointment, and misfortune, as well as passion and romance, but also of cheerful songs of revelry and a carefree attitude to life. Rebétiko as a music style developed in the Greek-speaking world and its dia
An increase of cycling is known to increase health, lower gas-emissions and lower traffic-congestion. In cities with a high modal-share of bicycling, a higher quality of life can be measured. “Supercykelvägar” in The Netherlands and Denmark are defined as forming the backbone of the regional cycling-network. Malmö is planning to implement six routes of “supercykelvägar” within the city and the fir
Management of intermittent renewable energy sources (RES) such as wind and solar is a significant issue for countries with interconnected electricity markets. Increasing amounts of electricity from intermittent RES increases the variability of electricity supply, causing electricity prices to become highly sensitive weather conditions. Unpredictable prices have a negative effect on new infrastruct
A very important aspect of the employees duty to the employer is to be loyal. The conflict between the freedom of speech and the employees loyalty duty is not new. However electronic trace like social media bring employees the possibility to present critics, disapproval and sometimes incorrect information to a large public. On the other hand the new technic also brings new possibilities to save th
This paper was set out to examine how discrimination lower incentives to attain human capital throughout different societal sectors and, thus, how human capital barriers affect economic growth. We aim to derive a generalized theoretical framework that is applicable to any group facing discrimination. Our secondary purpose is to apply the generalized theoretical framework to women and men in Sweden
This Report presents an evaluation method for fire and rescue service management. It focuses on success criteria and lays the groundwork for answering the question What is good management? In this report fire and rescue service management is defined as complex and the fire and rescue service as a complex system. This complicates evaluation, which now has to include complexity. A major part of this
The aim of this Master's thesis is to construct an algorithm that nds the optimal credit limit for an individual credit card holder. It should be optimal in the sense that the algorithm suggests the lowest credit limit required for reaching the business goal of generating "X SEK within d days after limit raise" for the issuer of the credit card. This is achieved in three stages. Firs
The concept of run-o triangles is widely used within the actuarial eld. Its purpose is to estimate Incurred But Not Reported claims for insurance portfolios, in order to set appropriate reserves that are in compliance with regulatory requirements as well as the company's risk appetite. In this thesis, a parametric approach is proposed, where the portfolios are modeled using non-stationary dist
This study is based on four unaccompanied young refugees' stories of their first experiences, and how they perceive their situation regarding the rights and acceptance as unaccompanied refugee children in Sweden. Method:Qualitative research method. Four semistructured interviews. Result: This study shows that unaccompanied refugees situation in Sweden do not always correspond to the reality th
The motivation to study the kind of problems appearing in this thesis has been ultrasound measurements of flows, from which velocity spectra along lines can be determined. These velocity spectra can mathematically be described by a new non-linear transform, here called the Doppler Spectral Transform (DST). The Doppler spectral transform has a very rich theory, into which some steps are taken here
Modern dead-ice environments in the glacier forefields of Brúarjökull, Iceland and Holmströmbreen, Svalbard were investigated with focus on landform and sediment genesis, as well as quantification of melting. Field monitoring and studies of multi-temporal aerial photographs, satellite imagery, and Digital Elevation Models (DEMs) provided data for the melting quantification. Sedimentological and ge
Rainfall characteristics of Kuala Lumpur, Malaysia, are studied in space and time; on a large scale, 550 km2, and long term scale to find out the monsoon influence, and on urban basin scale, 23 km2, to determine dynamic properties of rainfalls and spatial correlations, and on a point scale to determine the probabilities of very high rain intensities. The importance of spatial and temporal variabi
This thesis is based on studies of Lower Palaeozoic sedimentary successions within the central Scandinavian Caledonides. These deposits have been transported by considerable nappe displacement (several kilometres), and are today relatively isolated from the nearest coeval outcrops (Dalarna 250 km, Oslo Region 350 km). As a consequence, and due to the previously limited biostratigraphical control t
