Background: Data from 1998 showed that CT represents about 10% of all the diagnostic X-ray examinations and almost 70% of the total radiation dose from medical diagnostic examinations in Sweden. Because of this there is a strong need to minimize the radiation dose and adapt the dose to each patient’s examination area and anatomy. Today practically all-modern CT systems are delivered with automatic
Title: Critical success factors that influence the corporate venturing process Seminar date: 2013-05-02 Course: ENTN39 Internship and Degree Project Authors: Martin Zündorf & Marcus Holgersson Advisor/s: Joakim Winborg Purpose: We investigated the influence of different factors on the corporate venturing process. Therefore we combined several factors from the organizational level with cha
Risk measures such as Value at Risk are highly dependent on a sample of daily returns. The daily return can be measured in different intervals and this thesis examines how the choice of the daily return interval affects derivative pricing, risk measures, fund performance and products with collateral agreements. It is shown that the VaR measure varies significantly with the choice of daily return i
Directional crack growth criteria in compressed elastic–plastic materials are considered. The conditions at the crack tip are evaluated for a straight stationary crack. Remote load is a combined hydrostatic stress and pure shear, applied via a boundary layer assuming small scale yielding. Strains and deformations are assumed to be small. Different candidates for crack path criteria are examined. M
This textbook advocates patients’ empowerment for improving health outcomes and health system performance. It emphasizes the important implications of improving communication between patient and health professionals and the adherence to treatment regimens. Based on research including theories of Stages of Change and Decision Balance, and by incorporating examples from daily clinical practice, this
The research work that I describe in my thesis deals with three different heterogenisation approaches for synthesising a heterogeneous transition metal catalyst used for direct C-H activation reactions. The three heterogenisation approaches considered in my research are: (1) heterogenisation of a molecular catalyst on a polymer support using covalent bonds, (2) heterogenisation of a catalyst on a
A new Grain stream cipher, denoted Grain-128AEAD is presented, with support for authenticated encryption with associated data. The cipher takes a 128-bit key and a 96-bit IV and produces a pseudo random sequence that is used for encryption and authentication of messages. The design is based on Grain-128a but introduces a few changes in order to increase the security and protect against recent cryp
3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing. Even though there exist various pose estimation algorithms, they usually deal with common daily objects applied in lab environments. However, coping with real-world industrial objects is a much harder challenge for most pose estimation techniques due to 3D pose estimation is a crucial element for enabling robots to work in industrial environment to perform tasks like bin-picking or depalletizing.

Effects of a mindfulness-based program, Compassion and Attention in the Schools (Compas), were studied in 358 pupils in grades 5, 7, and 8 in Sweden. An experimental group undertook Compas practices in class three times a week during an eight-week period. A control group undertook content area academic lessons .

The operating range in HCCI mode is limited by the excessive pressure rise rate and therefore high combustion induced noise. The HCCI range can be extended with turbocharging which enables increased dilution of the charge and thus a reduction of combustion noise. When the engine is turbocharged the intake charge will have a high temperature at increased boost pressure and can then be regulated in The operating range in HCCI mode is limited by the excessive pressure rise rate and therefore high combustion induced noise.

Background: A hip fracture is a common cause of morbidity, functional disability, and decreased health-related quality of life (HRQOL). With demographic changes showing a growing proportion of older people, hip fractures will be an increasing challenge for healthcare services in the future. Hip fractures threaten the independence of individuals in their everyday lives. In Sweden, more than one thi
MI, motivational interviewing, is a counseling method for increasing a person's motivation for behavior change with a large prevalence in social work. MI emphasizes building trusting social worker-client relationships and is presented as concrete and simple to follow. MI's benefit is limited by actual opportunities for change through poverty, the labor market and health. The article aims to critic
Public health care systems face major challenges. The burden of resource constraints and continuous demands of rationings urge decision makers in countries like Sweden, Norway and the UK to find new financial solutions. One proposal that has been put forward is co-payments. In this presentation we explore ethical problems associated with co-payments in publicly funded health care systems. The issuPublic healthcare systems face major challenges. The burden of resource con-straints and continuous demands of rationings urge decision makers in countries like Sweden, Norway and the UK to find new financial solutions. One proposal that has been put forward is co-payment, where patients are given the option to pay the public healthcare provider for additional care, or more e
The aim of this article is to study how selected variables influence delays in train traffic. Data has been collected on train movements, timetables, weather and capacity utilization on a highly utilized single-track railway line in southern Sweden during 2014. Based on this dataset, we have analysed how different factors affect delays in passenger traffic. We measure delays in a novel way, as devThe aim of this article is to study how selected variables influence delays in train traffic.

Precise knowledge of the temperature during cutting processes is of high interest as the temperature of a cutting tool dictates the performance, and for the workpiece it controls the quality and integrity of the generated surface. For the first time, in this study, a novel technique has been developed utilizing phosphor thermometry for 2D surface temperature measurement of a cutting tool in metal
Air pollution is a global health problem and in Mozambique, indoor air pollution is primarily caused by cooking over an open fire. This study examines the potential of coconut charcoal as a cleaner cooking fuel and as a possible source of income for women in the village of Linga Linga, Mozambique. Previous research conducted in the village identified a need to investigate the willingness of the co
Biological neural network functionality depends on the vast number of connections between nodes, which can be challenging to implement artificially. One radical solution is to replace physical wiring with broadcasting of signals between the artificial neurons. We explore an implementation of this concept by light emitting/receiving III-V semiconductor nanowire neurons in a quasi-2D waveguide. They
From the end of the nineteenth century and one hundred years onward, home sewing was an important part of many women’s duties, but it was also a pleasure, something that existed parallel with the emerging mass-produced ready-to-wear industry. The paper patterns used for home dressmaking were often sold and distributed through women’s magazines. These pattern sections were both a kind of reader ser
