High-Quality Spatio-Temporal Rendering using Semi-Analytical Visibility

We present a novel visibility algorithm for rendering motion blur with per-pixel anti-aliasing. Our algorithm uses a number of line samples over a rectangular group of pixels, and together with the time dimension, a two-dimensional spatio-temporal visibility problem needs to be solved per line sample. In a coarse culling step, our algorithm first uses a bounding volume hierarchy to rapidly remove

A sorption balance study of water vapour sorption on anhydrous cement minerals and cement constituents

The phenomenon of water vapour sorption by powdered cement constituents exposed to different relative humidities and temperatures was studied. The individual clinker phases C3S, C2S, C(3)A, C(4)AF, calcium sulfates and CaO were tested. Using a water sorption balance, the amount of chemically and physically sorbed water per unit of surface area of the powders and the relative humidity at which wate

Annual direct medical cost of active systemic lupus erythematosus in five European countries

Objectives To evaluate the annual direct medical cost of managing adult systemic lupus erythematosus (SLE) patients with active autoantibody positive disease in Europe. Methods A 2-year, retrospective, multicentre, observational study was conducted in five countries (France, Germany, Italy, Spain and the UK). Data included patients' characteristics, disease activity and severity, flare assessments

Skill relatedness and firm diversification

Because of the importance of human capital, a firm's choice of diversification targets will depend on whether these targets offer opportunities for leveraging existing human resources. We propose to quantify the similarity of different industries' human capital or skill requirements, that is, the industries' skill relatedness, by using information on cross-industry labor flows. Labor flows among i

Ionic surfactants with polymeric counterions.

This review summarizes recent progress in our understanding of aquoeus "complex salts" of ionic surfactants with polymeric counterions. Complex salts are simplified versions of the much-studied mixtures of oppositely charged polyelectrolytes and surfactants, and are also good model systems to study the fundamentals of polyion-mediated forces in colloidal systems. Comparisons are made with conventi

Corporate-internal vs. national standard - A comparison study of two ergonomics evaluation procedures used in automotive manufacturing

Manufacturing corporations sometimes use corporate-internal procedures to evaluate and monitor the ergonomic status of the workplace. This article describes an industrial case study in the Swedish automotive sector, where an internally developed evaluation procedure was compared with a procedure based on a Swedish national standard provision. It was found that the national standard procedure tende

Watching television in later life: A deeper understanding of TV viewing in the homes of old people and in geriatric care contexts

A secret among staff at nursing homes is that they are often ambivalent about old residents spending so much time watching TV since it is a common cultural perception that it makes the viewer passive. The purpose of this paper is to highlight the importance of reflecting on the TV viewing habits old people bring with them when they move into geriatric care. The findings are based on a study involv

From the origin of sex-determining factors to the evolution of sex-determining systems

Sex determination is typically classified as either genotypic or environmental. However, this dichotomy obscures the developmental origin and evolutionary modification of determinants of sex, and therefore hinders an understanding of the processes that generates diversity in sex-determining systems. Recent research on reptiles and fish emphasizes that sex determination is a multifactorial regulato

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H -> gamma gamma, H -> ZZ* -> 4l and H -> WW* -> l nu l nu. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of root s = 7 TeV and root s = 8 TeV, corre

Effective emotions - the enactment of a work ethic in the Swedish meeting industry

The meeting industry – an encompassing term for services related to various kinds of professional meetings, from mega-conventions to the ordinary work meetings – is increasingly consolidated and legitimated as a specific sector in the service in-dustry. New professions such as meeting designers, meeting facilitators and meet-ing consultants are emerging, promoting new knowledge in this field. By f

Number-ratio fluctuations in high-energy particle production

In this article we will discuss the previously proposed quantity nu(dyn) [ C. Pruneau, S. Gavin, and S. Voloshin, Phys.Rev.C 66, 044904 (2002)], as a measure of the number-ratio fluctuations in high-energy particle production. We will show that nu(dyn) has pleasing mathematical properties making it ideal for the purpose. We will demonstrate its relation to two-particle correlations and how this me

Effects of work ability and health promoting interventions for women with musculoskeletal symptoms: A 9-month prospective study

Background: Women working in the public human service sector in 'overstrained' situations run the risk of musculoskeletal symptoms and long-term sick leave. In order to maintain the level of health and work ability and strengthen the potential resources for health, it is important that employees gain greater control over decisions and actions affecting their health - a process associated with the

Online impairments-aware routing within a path computation element

A Path Computation Element (PCE) is a computing device in a network capable of calculating paths. Once a PCE receives a path computation request, the PCE is suppose to provide a response within a reasonable short time. However, computing a feasible path is not a straightforward task, since the computational problem must consider several constraints in a short time. In this paper we propose an algo

Abstract in Norwegian Hensikten med denne rapporten er å få frem kunnskap om hvordan spørsmål om mer effektiv og miljøvennlig energibruk ivaretas ved boligutbygging. Rapporten fokuserer først og fremst på institusjonelle drivkrefter og barrierer knyttet til kommunale planog byggesaksprosesser, og hvordan dette påvirker ulike aktørers praksis. Sentrale spørsmål i studien er følgende: • Hvordan ivar

Current status of transplantation and organ donation in the Balkans-could it be improved through the South-eastern European health Network (SEEHN) initiative?

Organ donation and transplantation activity in the majority of Balkan countries (Albania, Bosnia and Herzegovina, Croatia, Macedonia, Moldova, Montenegro, Serbia, Romania and Bulgaria) are lagging far behind international averages. Inadequate financial resources, unclear regional data and lack of governmental infrastructure are some of the issues which should be recognized to draw attention and pr
