Due to restrictions following the Covid-19 pandemic,major changes regarding teaching have been called for. Sincestudents’ presence in lab classrooms has been very restricted alsophysical labs have had to be transformed into e.g. simulationsperformed at home or via remote connections. After lifting of therestrictions, hybrid learning where both physical and simulatedlab environment are combined hav
Symmetry and dominance breaking can be crucial for solving hard combinatorial search and optimisation problems, but the correctness of these techniques sometimes relies on subtle arguments. For this reason, it is desirable to produce efficient, machine-verifiable certificates that solutions have been computed correctly. Building on the cutting planes proof system, we develop a certification method
Throughout the past decade, neural network-based vision has been increasingly integrated into robots. It is well-known, however, that neural networks can be unreliable, especially when faced with inputs that differ from their training data. With the goal of making neural network-based vision more reliable for robotic applications, this thesis explores uncertainty estimation, and adaptability.A
Abstract:This doctoral thesis is addresses two topics in integrated circuit design: multiband direct conversion cellular receivers for cellular frequencies and beam steering transmitters for millimeter wave communication for the cellular backhaul. The trend towards cellular terminals supporting ever more different frequency bands has resulted in complex radio frontends with a large number of RF in
The vehicle-estimation problem is approached by fusing measurements from wheel encoders, an inertial measurement unit, and (optionally) a global positioning system in a Rao-Blackwellized particle filter. In total 14 states are estimated, including key variables in active safety systems, such as longitudinal velocity, roll angle, and wheel slip for all four wheels. The method only relies on kinemat
There has been little interest in the longitudinal movement of the arterial wall. It has been assumed that this movement is negligible compared with the diameter change. Using a new high-resolution noninvasive ultrasonic method, we measured longitudinal movements and diameter change of the common carotid artery of 10 healthy humans. During the cardiac cycle, a distinct bidirectional longitudinal m
AIMS: Cardiovascular disease (CVD) is one of the leading causes of mortality and morbidity worldwide, including in Sweden. The main aim of this study was to explore the temporal trends and spatial patterns of CVD in Sweden using spatial autocorrelation analyses.METHODS: The CVD admission rates between 2000 and 2010 throughout Sweden were entered as the input disease data for the analytic processes
The aim of this paper is to critically examine, discuss, draw conclusions, and come up with ideas how to harmonize GIS education in order to realize the envisaged clientele benefits globally. The paper draws experiences and lessons learnt, with examples from ongoing joint GIS MSc programs/courses being implemented in Mozambique, Rwanda, and Uganda. All the five courses (3 in Uganda, 1 in Mozambiqu
Gaussian models are frequently used for road elevations. However, these models are often only valid for short sections of the road. Here we present a comprehensive approach to describe various aspects of road surface/elevation by using extensions of Gaussian models arising from random gamma distributed variances. These random variances result in the Laplace distribution and thus we refer to the so
Amiralsgatan, Rosengård, is a highway area in Malmö. It consists of segregated streets with no connection between them with limited social activities. Rosengård’s population is mainly immigrants, living in the Million Housing Program, hence low-wage living, which makes them segregated from the rest of Malmö. The aim of this project is to integrate Rosengård into the rest of Malmö by achieving a he

Popular Abstract in Swedish Aneurysm är ett sjukdomstillstånd som är känt sedan ca 2000 år före vår tideräkning, och bukaortaaneurysm (bråck på stora kroppspulsådern i buken) beskrivs i publikationer från 1500-talet. På 1800-talet försökte man sig på att behandla med ligering, tyvärr med dåligt resultat, och först på 1920-talet beskrivs den första lyckade ligeringen. Behandling med graftrekonstrukThe incidence of abdominal aortic aneurysms (AAA) is increasing. The risk of rupture is related to diameter. However, rupture may occur also in small AAA. To evaluate the size of an aneurysm when related to the predicted normal aortic diameter might be a better predictor of risk. AAA:s, range 40-55 mm were studied in relation to gender. No difference in AAA diameter was found. However, body surfac
We study geometric reconstruction problems in one-dimensional retina vision. In such problems, the scene is modeled as a two-dimensional plane, and the camera sensor produces one-dimensional images of the scene. Our main contribution is an efficient method for computing the global optimum to the structure and motion problem with respect to the L-infinity norm of the reprojection errors. One-dimens
Abstract in UndeterminedIn this paper, a number of channel estimation algorithms for iterative receivers are compared for the case of an up-link orthogonal frequency division multiplexing interleave division multiple access (OFDM-IDMA) system. Both pilot based algorithms, used to obtain an initial estimate, as well as semi-blind decision-directed algorithms working as a component of the iterative
Connecting science to political agenda-setting is essential for a sustainable transition and acceptable politics. This task is complicated by phenomena like post-truth, for which facts are a non-issue. However, post-truth is not the only issue. The practice of political spin, in which the significance of facts is reconstructed according to specific interests poses another threat to scientific cred
