During the last years, virtual 3D city models have been widely used in application fields such as urban planning, environment simulations, and disaster management. With the development of high-rise buildings and the increasing densely built-up areas, an increasing number of authorities and companies have shown interest in integrating 3D city models with the cadastre. This is because on one hand, t
A major challenge when designing general purpose graphics hardware is to allow efficient access to texture data. Although different rendering paradigms vary with respect to their data access patterns, there is no flexibility when it comes to data caching provided by the graphics architecture. In this paper we focus on volume ray-casting, and show the benefits of algorithm-aware data caching. Our M
Introduction Using body mass index (BMI) as a proxy, previous Mendelian randomization (MR) studies found total causal effects of general obesity on polycystic ovarian syndrome (PCOS). Hitherto, total and direct causal effects of general- and central obesity on PCOS have not been comprehensively analyzed. Objectives To investigate the causality of central- and general obesity on PCOS using surrogat
Choices of regularization parameters are central to variational methods for image restoration. In this paper, a spatially adaptive (or distributed) regularization scheme is developed based on localized residuals, which properly balances the regularization weight between regions containing image details and homogeneous regions. Surrogate iterative methods are employed to handle given subsampled dat
This thesis compares how Sweden and Finland’s contrasting exchange rate regimes shaped their export sector performance during the 2008 Global Financial Crisis. While both are small, open Nordic economies, Sweden maintained a floating currency and independent monetary policy, whereas Finland adopted the euro and ceded monetary control to the European Central Bank. The study evaluates export revenue
The movement and distribution of ecologically important herbivores such as elephants are of great significance to conservation biologist seeking to understand the fundamental triggers that influence their mobility and the extent to which these parameters affect how they utilize their immediate and surrounding resources. The recent advancement in animal tracking technology coupled with the availabi
Popular Abstract in Swedish Många av dagens stora folksjukdomar, såsom cancer, diabetes och hjärt-kärlsjukdomar, kopplas i allt högre grad samman med olika riskfaktorer som beror på förändringar i arvsmassan. Dessa nya kopplingar har möjliggjorts tack vare den extrema utveckling av genetiska mätmetoder som har skett under de senaste 15 åren. Med de nya metoderna kan förekomsten och aktiviteten hosThis thesis deals with methods for extracting robust and relevant information from high-dimensional data sets, and statistically guided visualization methods for representing the data in an informative and easily accessible way. High-dimensional data sets are becoming increasingly prevalent in many different scientific disciplines. In this thesis, we focus particularly on so called "omics" data. T
The present study describes the development and testing of a tool for dolphin research. This tool was able to visualize the dolphin echolocation signals as well as function as an acoustically operated “touch screen”. The system consisted of a matrix of hydrophones attached to a semi-transparent screen, which was lowered in front of an underwater acrylic panel in a dolphin pool. When a dolphin aime
How was the atomic age visualized in Egypt in the years immediately after the creation of the bomb? What role did gendered images, symbols and metaphors play in narrating and normalizing nuclear technology? How can these help us understand nuclear policy today? This article engages visual and textual media, including satirical magazines, cultural journals and film. It presents a plurality of image
This article is a Bioarchaeology of Care and Disability focused analysis of an individual who suffered a severe fracture of the left knee in Late Medieval Lund, Scania (1300–1536 CE). We question the degree to which written sources from the period represent the reality of the disability experience, and to that end how identities intersect in the Medieval urban landscape. Following an index of care
Background: Three-dimensional time-resolved (4D) phase-contrast (PC) CMR can visualize and quantify cardiovascular flow but is hampered by long acquisition times. Acceleration with SENSE or k-t BLAST are two possibilities but results on validation are lacking, especially at 3 T. The aim of this study was therefore to validate quantitative in vivo cardiac 4D-acquisitions accelerated with parallel i
A high spatiotemporal resolution technique for instantaneous flow field measurement has been developed, enabling one-dimensional velocimetry and flow field visualization within a converging–diverging nozzle. By employing femtosecond laser-induced long-lived, high-intensity plasma emission in a CO2/N2 gas flow, coupled with an ICCD camera, we achieved instantaneous one-dimensional velocity measurem
Extracellular matrix (ECM) surrounding conidia and germlings of B. sorokiniana was studied using light microscopy (LM), scanning (SEM) and transmission electron microscopy (TEM). Conidial ECM surrounding dry-inoculated, ungerminated conidia was fluid-like and observed only using a cryo-preparation technique, suggesting that the material was water soluble. ECM enveloping germlings appeared fibrilla
The early science results from the new generation of high-resolution stellar spectroscopic surveys, such as Galactic Archaeology with HERMES (GALAH) and the Gaia European Southern Observatory survey (Gaia-ESO), will represent major milestones in the quest to chemically tag the Galaxy. Yet this technique to reconstruct dispersed coeval stellar groups has remained largely untested until recently. We
INTRODUCTION: Reporting of sex and gender analysis in medical research has been shown to improve quality of the science and ensures findings are applicable to women and men. There is conflicting evidence on whether efforts by funding agencies and medical journals to encourage reporting of sex and gender analysis has resulted in tangible improvements. This study mapped the inclusion of sex and gend
Upplevelserummet blir alltmer viktigare. Tidigare undersökningar om upplevelserummet har enbart fokuserats på de fysiska faktorerna. Men vad som även behöver undersökas är vilka faktorer utöver de fysiska som kan påverka en människas uppfattning om upplevelserummet och beteendet. Vårt syfte är att undersöka vilka faktorer som främst påverkar samt hur dessa påverkar kundens kvalitetsuppfattning av
Urbanization is driving cities to grow, often through urban densification. Utilising computer-based simulations executed over 3D representations of the city is imperative in addressing the challenges posed by implementing sustainable urban densifications; like ensuring adequate access to daylight and limiting noise pollution. However, since these simulations are usually resource-intensive, timecon
