High-quality video is being increasingly delivered over Internet Protocol networks, which means that network operators and service providers need methods to measure the quality of experience (QoE) of the video services. In this paper, we propose a method to speed up the development of no-reference bitstream objective metrics for estimating QoE. This method uses full-reference objective metrics, wh

Several room acoustic parameters have to be considered in ordinary public rooms, such as offices and classrooms, in order to present the actual conditions, thus increasing demands on the acoustic treatment. The most common acoustical treatment in ordinary rooms is a suspended absorbent ceiling. Due to the non-uniform distribution of the absorbent material, the classical diffuse field assumption is
This is the report of the work carried out for project "Dagsljusanvändning i byggnader" of the Swedish Energy Agency, project number 41816-1. This research provides background scientific information on the daylight performance of multi family apartment blocks located in Stockholm, and Örebro, Sweden. A sample of 54 buildings that consist of 10 888 individual rooms was evaluated using advanced dayl
Objective: To study the difference in incidence and risk of fragility fractures between rheumatoid arthritis (RA) patients followed up early in the disease and the general population in Sweden; and the fracture risk changes in RA patients diagnosed in the 1990s and 2000s because of earlier, more potent pharmacological treatment in the later period. Method: Patients with early RA were recruited fro
Background—The effects of ticagrelor pretreatment in patients with ST-segment–elevation myocardial infarction undergoing primary percutaneous coronary intervention (PCI) is debated. This study investigated the effects of ticagrelor pretreatment on clinical outcomes in this patient group. Methods and Results—Patients with ST-segment–elevation myocardial infarction undergoing primary PCI were includ
Ligand exchange on square-planar Pt(1,4-dithiane)2(2+), Pd(1,4-dithiane)2(2+), and Pt(Me2S)4(2+) has been studied as a function of temperature and pressure by H-1 NMR line-broadening, isotopic labeling, and magnetization transfer experiments with deuteriated nitromethane as solvent. Second-order rate constants and activation parameters are as follows: for 1,4-dithiane exchange on Pt(1,4-dithiane)2
Mutations in the genes that code for collagen VI subunits, COL6A1, COL6A2, and COL6A3, are the cause of the dominantly inherited disorder, Bethlem myopathy. Glycine mutations that interrupt the Gly-X-Y repetitive amino acid sequence that forms the characteristic collagen triple helix have been defined in four families; however, the effects of these mutations on collagen VI biosynthesis, assembly,
New robot applications increasingly require external sensing to accomplish robustness and performance despite the variations and uncertainties that come with the increasing demands on flexibility for manufacturing of customized products. The demands on productivity then require high performance, which for well known feedback-control reasons means short response times from external process event to
The concept of run-o triangles is widely used within the actuarial eld. Its purpose is to estimate Incurred But Not Reported claims for insurance portfolios, in order to set appropriate reserves that are in compliance with regulatory requirements as well as the company's risk appetite. In this thesis, a parametric approach is proposed, where the portfolios are modeled using non-stationary dist
Det har blivit allt vanligare med direkthandel i stora enplansvaruhus, där kunder plockar sina varor direkt från pallställ. Dessa pallställ går ofta från golv till tak och är lastade med varor ända upp till taket. I taket förekommer ofta fackverksbalkar i stål som bär upp stomsystemet. Vid en eventuell brand i ett pallställ kan det bli stor lokal flampåverkan med snabb upphettning i delar av fackve
Sverige har beslutat att år 2020 implementera barnkonventionen och konventionen blir då erkänd som svensk rätt. Barnets rätt att komma till tals i alla förfaranden som berör barnet är en grundläggande princip i barnkonventionen. Norge implementerade barnkonventionen år 2003 vilket resulterade i att barnets rättigheter stärktes. Barnets rätt att komma till tals är lagstadgad i föräldrabalken men t
BACKGROUND: The ankle region is frequently involved in juvenile idiopathic arthritis (JIA) but difficult to examine clinically due to its anatomical complexity. The aim of the study was to evaluate the role of ultrasonography (US) of the ankle and midfoot (ankle region) in JIA. Doppler-US detected synovial hypertrophy, effusion and hyperemia and US was used for guidance of steroid injection and to
Aims Oral anticoagulation with vitamin K antagonists (VKAs) for stroke prevention in atrial fibrillation (AF) is effective but has significant limitations. AZD0837, a new oral anticoagulant, is a prodrug converted to a selective and reversible direct thrombin inhibitor (AR-H067637). We report from a Phase II randomized, dose-guiding study (NCT00684307) to assess safety, tolerability, pharmacokinet
Sverige är sedan 1971 ansluten till FN-konventionen om avskaffande av alla former av rasdiskriminering. Konventionen tillkom som en reaktion mot rasdiskriminerande förtryck i form av apartheid och kolonialism. Varje konventionsstat är enligt konventionens art. 4(b) skyldig att olagligförklara och förbjuda organisationer som främjar och uppmanar till rasdiskriminering. Trots upprepad kritik från In 1971, Sweden ratified the United Nations convention on the elimination of all forms of racial discrimination. It was established as a reaction to racial oppression, such as apartheid and colonialism. All state parties are, under article 4, obliged to prohibit and criminalise organisations who in any way promote or encourage racial discrimination. Sweden has, in spite of criticism from the conve
Active suspensions of microswimmers such as bacteria or microalgae are found in oceans or lakes, and within living organisms, such as the human body. These suspensions can exhibit complex flow patterns and enhanced diffusion of passive tracer particles due to the advection from the long-ranged dipolar flow fields of the swimmers. The diffusion of tracers at varying radii is poorly understood but o

The app-industry today is ruled by two giants, namely Android and iOS. For companies and developers, it is essential to deliver their product to the majority of users, thus adapting to both platforms. The platforms involve their own way of developing applications and only barely resembles each other. A problem that the industry faces resides here, having to hire staff with knowledge in either Andr
