The topic of the thesis is the analysis of velocity encoded medical images, acquired using magnetic resonance imaging or other means. The application in mind is to use such data to determine the motion and deformation of the human heart, which is of clinical and physiological interest. As the velocity measurements are noisy and degraded, an important issue is the regularization of the measurements
Ergonomics are, in most cases, focusing on the human being when evaluating assembly system designs. This results in the human performance being expressed isolated from the technical environment. On the other hand, technicians are prone to concentrate on the hardware. These conditions underline the need to pursue a more integrated evaluation and design procedure in order to avoid the drawbacks of t
High-pressure torsion was used for the deformation processing of high-purity aluminum (4N-Al), while high-resolution electron-backscatter diffraction was used for the analysis of evolution of qualitative and quantitative microstructural characteristics. This study reveals a rather full picture of microstructure evolution in the high stacking fault energy fcc material and makes a continuous link be
A growing body of studies emphasizes the discovery of opportunities and the decision to exploit them as the essence of entrepreneurial activity. Following this stream of research, we present a study of the influence of entrepreneurs’ career experience and career motives on two alternative modes of decision making logic; causation and effectuation. Causal reasoning is a process that rests on logic
This study explores entrepreneurial decision-making with respect to non-analytic and analytic behaviour among novice and expert entrepreneurs. In order to understand and categorise subcomponents, or strategies, of these two styles of decision-making think-aloud protocols were used. By exploring and comparing behaviour within various entrepreneurial scenarios, and segmenting it using precise catego
After the Fukushima accident in 2011, Sweden and Germany acted differently. Sweden stressed its nuclear power plant while Germany made a complete turn and decided on a nuclear power settlement by 2022. It raises questions why Germany and Sweden acted differently after the Fukushima accident. The purpose of this thesis is to analyze why a political decision was taken on a nuclear power phase out in
This case study explores how members of a large complex organization make sense of its efforts to be more adaptable. Using ideas from institutional theory, we problematize efforts toward adaptability and identify adaptability as an area where organizations engage in some degree of hypocrisy, meaning that they talk about being flexible to stay competitive in a fast-paced environment, but often act
In the current study, the aim was to investigate whether attentional bias—an automatic and nonconscious pre-attentive process of filtering sensory information for emotional relevance—could be induced in normal students, by manipulating levels of stress. In a within-subject experimental design where each participant completed 3 word search puzzles, it was predicted that the ratio at which participa
Företagskultur är ett komplext fenomen som fått allt större plats på ledningsnivå. Att en stark företagskultur har en positiv korrelation till goda ekonomiska resultat är något många forskare är överens om, men när det gäller frågan om hur företag bör hantera socialiseringen av en ny kandidat, finns det många olika teorier. Denna uppsats redogör för hur fem olika företag skapat starka företagskultOrganisational culture is a complex phenomenon that is widely discussed on manage-mental levels. Many researchers agree about the fact that a strong organisational culture correlates with successful financial results, but when discussing how companies socialize an individual into a desirable behavior, there are many different contradictory theories. In this thesis, we explore how five different co
This thesis examines the representation of rape in J. M. Coetzee’s Disgrace (1999), Shani Motoo’s Cereus Blooms at Night (1996), Ian McEwan’s Atonement (2001), and Joyce Carol Oates’ Rape: A Love Story (2003). The analysis of the novels is introduced by a background chapter that outlines the literary history of the rape metaphor and feminist attitudes towards the representation and definition of r
Fjärranalys av insekter med laserljus I detta examensarbete utvecklades ett instrument som använder en bredbandig ljusstråle för fjärranalys av insekter. Tjockleken av en jungfrusländas vinge mättes på 87 m avstånd och med en 4 nm noggrannhet. Insekter spelar en huvudroll i ekosystemet och är avgörande för den biologiska mångfalden. Att urskilja och övervaka var miljontals insekter i våra miljöeInsects play a major role in the ecosystem and are an important factor for biodiversity. Using laser remote sensing to distinguish and monitor the millions of insects in-situ, holds large potential to speed up and improve the otherwise time consuming process of trapping and subsequent analysis. In this work, the spectral analyser for an elastic hyper spectral lidar in the SWIR, with 64 effective s
As Artificial Intelligence (AI) is progressing to take over decision making in different industries, the threat that comes with the use of these systems is also increasing. One major threat is the risk of these systems acting biased, causing discrimination to parts of the population. To tackle the risk of AI systems acting biased it is important to understand how these biases originate in the firs
This study examines whether the European Commission and the European External Action Service (EEAS) exercise collaborative leadership in the European Union's (EU) external climate security policy. While the academic debate acknowledges that both actors are very engaged in addressing external climate-related security risks, it does not answer whether they exercise a leadership role. Theoretical
Den 1 juli 2018 trädde den så kallade samtyckeslagstiftningen ikraft, vilket innebar en stor förändring i den svenska regleringen av våldtäktsbrottet. Lagstiftningen blev nu frivillighetsbaserad och samtidigt infördes ett nytt brott, oaktsam våldtäkt. Straffansvar i våldtäktsmål är därmed även aktuellt då den tilltalade agerat grovt oaktsamt. Denna uppsats syftar till att klargöra hur domstolar reIn 2018, Sweden passed a new law regarding rape, which is based on consent. Prior to this, a certain amount of force or threat was required, but the current legislation is based on the lack of voluntary participation. A new offense was passed, negligent rape. Thus, criminal liability for rape does not only come in question in cases of intent, but also in cases of gross negligence. The main purpose
After almost two years living in Malmö, I discovered Nyhamnen by reading about the municipality plans for the area in a local newspaper. The mere realization that I was not aware of such a large area, only five minutes walking from the central station was both surprising and challenging. Since then, the aim of this thesis has been to develop an urban proposal that even though it is an academic exe
Many agree that estimating portfolio risks has better estimation possibilities, than estimations on returns. Therefore investors attempts to construct better, more efficient riskmanaged portfolios by diversifying portfolios through factors rather than traditional asset classes. This entails very often in estimations of correlation matrices so complex it cannot be fully analyzed. Hierarchical clust
This thesis is a study of the public social life of children in an urban environment and of implementation of techniques and tools that would transform urban spaces in a typically large metropolitan city into a child friendly space. The common conception of children as the future citizen rather than as active citizens have lead to completely ignoring the needs of children during the designing proc
