Abstract in UndeterminedThis article presents an integrated environment for application scheduling, binding and routing used for the run-time reconfigurable, operator based, ROMA multimedia architecture. The environment is very flexible and after a minor modification can support other reconfigurable architectures. Currently, it supports the architecture model composed of a bank of single (double)
The effect of disperse phase volume fraction on the turbulence in a scale model of a high-pressure homogenizer was studied experimentally. Velocity fields of the continuous phase were measured using particle image velocimetry. Refractive index matching combined with digital filtering enabled measurement with disperse phase present. Geometry and physical properties were carefully scaled in order to
Abstract As custom multicore architectures become more and more common for DSP applications, instruction selection and scheduling for such applications and architectures become important topics. In this paper, we explore the effects of defining the problem of finding an optimal instruction selection and scheduling as a constraint satisfaction problem (CSP). We incorporate methods based on sub-grap
For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and o
Light field reconstruction algorithms can substantially decrease the noise in stochastically rendered images. Recent algorithms for defocus blur alone are both fast and accurate. However, motion blur is a considerably more complex type of camera effect, and as a consequence, current algorithms are either slow or too imprecise to use in high quality rendering. We extend previous work on real-time l
Soot, which is produced from biomass burning and the incomplete combustion of fossil and biomass fuels, has been linked to regional and global climate change and to negative health problems. Scientists measure the properties of soot using a variety of methods in order to quantify source emissions and understand its atmospheric chemistry, reactivity under emission conditions, interaction with solar
Providing accessible, acceptable and appreciated public transport for elderly people is essential. This work studies the relation between elderly people’s preferences of standard factors in different public transport systems, and their physical capacity. Three public transport systems are focused, service route traffic, trunk route traffic and special transport service, which demand different capa
Since the 1960s, product designers, architects, lighting planners, gamers and scientific visualizaiton specialists have craved the ability to work in real-time three-dimensional photorealistic virtual worlds. The authors, one specializing in making computer graphics more convincing and the other focusing on making them faster, present the achievements and challenges in the race for real-time photo
Den digitala teknikens framsteg möjliggör för företag att ha mer flexibla modeller för förmedling av varor och tjänster till konsumenterna. I detta nya eko-system, vilket brukar refereras till som gig-ekonomin, organiseras arbete via digitala plattformar. Gig-arbete som förmedlas via digitala plattformar skapar ett förhållande mellan tre parter, där det finns en beställare, en plattform och en utfDigitalization enables companies to establish more flexible business models when offering services and merchandise to its consumers. In this new eco-system, work is organized via digital labour platforms. This phenomenon is typically referred to as the gig-economy. The platform connects a so-called ’gig-worker’ to a buyer of a service. This tri-party relationship blurs the otherwise traditional wo
Internet of Things (IoT), det vill säga fysiska objekt med inbyggd elektronik som kan kopplas upp mot internet och styras eller utbyta data över nätet, har idag blivit en självklar del i många personers vardag. Det kan vara allt från hälsoarmband och kylskåp, till glödlampor och termostater. Som förutspås har vi dock ännu inte sett det stora genombrottet för denna teknik och vad den kan komma att The Internet of Things (IoT), i.e. physical objects with embedded electronics that can be connected to the internet and be controlled or exchange data over the network, has become an integral part of many people's daily lives. IoT devices can be anything from fitness trackers and refrigerators to light bulbs and thermostats. However, as is being predicted, we have yet to see the major breakthr
“I choose you, of my own free will”, en B-uppsats av Sofia Gripse och Veronika Persson vid Institutionen för kommunikation, Lunds universitet. Denna studie syftar till att undersöka hur kärlek och romantiska relationer konstrueras och representeras i säsong tre av tv-serien "The Summer I Turned Pretty". Med utgångspunkt i en kvalitativ innehållsanalys analyseras hur heteronormativa föres
Mat är väsentligt för människan och är även en stor del av hennes kultur. Då mat är en så stor del av människans vardag så är det inte konstigt att det även förekommer i det innehåll hon publicerar på sociala medier som Instagram. Vi har myntat begreppet slampig matlagning som innefattar det matinnehåll på internet som likt food porn enbart ska konsumeras med ögonen. Till skillnad från food porn,

In this study, a hydrochemical and biological investigation, and a vulnerability assessment were conducted on the Los Bambinos aquifer during the spring of 2020. A literature study on previous studies conducted in the area was also made. This aquifer is located on the southwestern slope of the Barva volcano, northeast of Alajuela, Costa Rica. The hydrochemical investigation found the groundwater t
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
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
