In this paper, we present a new approach to conservative bounding of displaced Bézier patches. These surfaces are expected to be a common use case for tessellation in interactive and real-time rendering. Our algorithm combines efficient normal bounding techniques, min-max mipmap hierarchies and oriented bounding boxes. This results in substantially faster convergence for the bounding volumes of di
Seven aliphatic dicarboxylic acids (C3-C9) along with phthalic acid, pinic acid and pinonic acid were determined in 35 aerosol (PM10) samples collected over the year at Vavihill sampling station in south of Sweden. Mixture of dichloromethane and methanol (ratio 1:3) was preferred over water for extraction of samples and extraction was assisted by ultrasonic agitation. Analytes were derivatized usi
Background: The merozoite surface protein 1 (msp1) is one of the most studied vaccine candidate genes in mammalian Plasmodium spp. to have been used for investigations of epidemiology, population structures, and immunity to infections. However methodological difficulties have impeded the use of nuclear markers such as msp1 in Plasmodium parasites causing avian malaria. Data from an infection trans
Recently, the performance of many-light algorithms, where thousands of light sources are used to compute the lighting in a scene, has improved so much that they have reached the realm of real-time rendering. In general, the algorithm that is considered “best” is the one that is the fastest in terms of time per frame. Given that power efficiency may become or already is one of the most important op
Since the emulsification in the High-Pressure Homogenizer (HPH) is controlled by hydrodynamic forces, the turbulent flow field in the valve region is of significant interest. Computational Fluid Dynamics (CFD) simulations have been used for this in many studies. However, there are reasons to question if the utilized turbulence models, with their inherent assumptions and simplifications, could accu
In this paper we address the problem of translating high-level stream programs, such as those written in MPEG's RVC-CAL dataflow language, into implementations in programmable hardware. Our focus is on two aspects: sufficient language coverage to make synthesis available for a large class of programs, and methodology and tool support providing analysis and guidance to improve and optimize an initi
From a control design point of view, modern diesel engines are dynamic, nonlinear, MIMO systems. This paper presents a method to find low-complexity black-box dynamic models suitable for model predictive control (MPC) of NOx and soot emissions based on on-line emissions measurements. A four-input-five-output representation of the engine is considered, with fuel injection timing, fuel injection dur
Partitioning and mapping are important design decisions in exploiting the parallelism of programs that are to be run on systems with multiple processing elements. In this paper we introduce a fast, incremental approach for mapping dynamic dataflow programs to multiprocessor systems. We use causation traces and architecture descriptions as input for the mapping process that devises several heuristi
Particle image velocimetry is performed on a model of a high pressure homogenizer, scaled for qualitative similarity of the one phase turbulent flow field in a production scale homogenizer. Flow fields in gap entrance, gap and gap outlet chamber are obtained with high resolution. The measurements show gap flow development and formation of a turbulent wall adherent jet when exiting into the outlet
Europeiska rådets förslag till ett direktiv om tillbörlig aktsamhet för företag i fråga om hållbarhet (”Förslaget”) syftar till att införa skyldigheter för vissa företag (”Företag/Företaget”) relaterat till hållbarhet. Ett av skälen till Förslaget var framväxten av globala värdekedjor, som tenderar att ge upphov till kränkningar av mänskliga rättigheter. Förlagan till Förslaget var Förenta nationeThe European Council’s proposal for a corporate sustainability due diligence directive (the “Proposal”) aims to introduce obligations and respon-sibilities for some companies (“Company/Companies”) related to sustainability matters. Part of the reasons for the Proposal was the emergence of global value chains, which are prone to contain human rights violations. The model for the Proposal was the Un
The inability to provide adequate education for refugee children in Transit and Reception Centres in the Republic of North Macedonia during the refugee crisis (2016-2017), defines the context-specific precarious conditions that stimulated teachers on-the-ground to seek new educational methods. The research questions inquire about the teachers’ methods outside the scope of formal/non-formal educati
This thesis exists within the debate of sustainable environmental management, examining the potential of rights of nature in overcoming problems caused by the current neoliberal conservation paradigm such as inequalities in power, lack in indigenous inclusion, as well as using contextually inappropriate approaches. In examining this a qualitative comparative case study research design is applied o
This chapter examines elite polarisation as a challenge to governance in parliamentary democracies. We emphasise the distinction between ideological polarisation based on substantive policy disagreements from affective polarisation, characterised by identity-based animosity that creates barriers to cooperation even when policy compromise might otherwise be possible. While parliamentary regimes hav
This position paper examines the growing dominance of health economics in Swedish healthcare governance and argues that its elevated epistemic authority produces significant risks for the sustainability and ethical integrity of care systems. Drawing on feminist theories of care and critical political economy, the paper interrogates the assumption that care can be adequately represented, valued, or
I Sverige är aktiebolaget idag vår vanligaste associationsform och fördelarna är många. Den förmod¬ligen starkaste av dem är regeln om det begränsade ansvaret för aktieägare. Genom denna regel åtnjuter aktieägare skydd mot att behöva gälda bolagets borgenärer med mer än det redan satsade aktiekapitalet. Med detta som bakgrund kan det begränsade ansvaret sägas vara en direkt förutsättning för förveIn Sweden, the most common type of company is the limited stock company (aktiebolag), which brings about several advantages. The strongest one is probably the shareholders’ limited liability. By this rule, the stock owners acquire protection from having to atone for any company debt exceed¬ing the already submitted equity stock. Keeping this in mind, one can consider the limited liability being an
In this paper, we show that a software implementation of IND-CCA-secure Saber key encapsulation mechanism protected by first-order masking and shuffling can be broken by deep learning-based power analysis. Using an ensemble of deep neural networks trained at the profiling stage, we can recover the session key and the secret key from 257 × N and 24 × 257 × N traces, respectively, where N is the num
Cavitation is common in high-pressure homogenizers, and has severe negative effects such as noise and mechanical wear, but may also have a beneficial effect in promoting fragmentation. Greater knowledge concerning cavitation in the homogenizer valve is thus important in optimizing the design and utilization of emulsification equipment. The aim of this study was to locate the region of cavitation a
