Global Optimization in Computer Vision: Convexity, Cuts and Approximation Algorithms

Computer vision is today a wide research area including topics like robot vision, image analysis, pattern recognition, medical imaging and geometric reconstruction problems. Over the past decades there has been a rapid development in understanding and modeling different computer vision applications. Even though much work has been devoted to modelling different problems, less work has been spent on

Investigation of local flame structures and statistics in partially premixed turbulent jet flames using simultaneous single-shot CH and OH planar laser-induced fluorescence imaging

We report on the application of simultaneous single-shot imaging of CH and OH radicals using planar laser-induced fluorescence (PLIF) to investigate partially permixed turbulent jet flames. Various flames have been stabilized on a coaxial jet flame burner consisting of an outer and an inner tube of diameter 22 and 2.2 mm, respectively. From the outer tube a rich methane/air mixture was supplied at

Benchmark Simulation Model No 2: finalisation of plant layout and default control strategy

The COST/IWA Benchmark Simulation Model No 1 (BSM1) has been available for almost a decade. Its primary purpose has been to create a platform for control strategy benchmarking of activated sludge processes. The fact that the research work related to the benchmark simulation models has resulted in more than 300 publications worldwide demonstrates the interest in and need of such tools within the re

Ohlin on the Great Depression : Ten Newspaper Articles 1929–1935

Bertil Ohlin was a most active commentator on current economic events in the interwar period, combining his academic work with a journalistic output of an impressive scale. He published more than a thousand newspaper articles in the 1920s and 1930s, more than any other professor in economics in Sweden. Here we have collected 10 articles by Ohlin, translated from Swedish and originally published i

Age- and gender-specific mortality rates in childhood hypertrophic cardiomyopathy

Aims Hypertrophic cardiomyopathy (HCM) is the commonest inherited cause of sudden cardiac death in children; current guidelines suggest HCM screening after 12-15 years of age. The study aims to establish the age range at highest risk. Methods and results Cohort study from six regional centres of paediatric cardiology, including children presenting with sudden death; n = 150 (59% = male; 39% famili

Prescribed physical activity. A health economic analysis.

Popular Abstract in Swedish Det finns övertygande bevis för att fysisk inaktivitet ökar såväl sjuklighet som dödlighet när det gäller flertalet av våra vanligaste folksjukdomar. Inaktivitet är den globalt sett fjärde största riskfaktorn och orsak till förtida död, efter högt blodtryck, tobak och högt blodsocker. Enligt WHO:s beräkningar uppgår antalet dödsfall i världen orsakat av inaktivitet tillThe overall aim of this thesis was to estimate health economic consequences of the four-month primary care program ”Physical Activity on Prescription (PAP)”. Inactivity means a highly increased independent risk factor for public health diseases and morbidity, and is an economic burden to society. Evidence for cost effective interventions aiming at increasing physical activity (PA) level among inac

Biological effects of 2-oxoglutarate with particular emphasis on the regulation of protein, mineral and lipid absorption/metabolism, muscle performance, kidney function, bone formation and cancerogenesis, all viewed from a healthy ageing perspective state of the art - review article

The fact that men and women are living longer than they have ever done before is something in which we can all rejoice. However, the process of ageing is associated with changes in skeletal, muscular, gastrointestinal, neural hormonal and metabolic processes that seriously affect an individual's performance and quality of life. Indeed, Such changes can be contributory to a loss of independence in

Monte Carlo feature selection and rule-based models to predict Alzheimer's disease in mild cognitive impairment

The objective of the present study was to evaluate a Monte Carlo feature selection (MCFS) and rough set Rosetta pipeline for generating rule-based models as a tool for comprehensive risk estimates for future Alzheimer's disease (AD) in individual patients with mild cognitive impairment (MCI). Risk estimates were generated on the basis of age, gender, Mini-Mental State Examination scores, apolipopr

Dynamic early Holocene vegetation development on the Faroe Islands inferred from high-resolution plant macrofossil and pollen data

Vegetation dynamics during the earliest part of the Holocene (11,250-10,250 cal yr BP) have been reconstructed from a lacustrine sequence on Sandoy, the Faroe Islands, using detailed plant macrofossil and pollen evidence. The plant macrofossils suggest the initial vegetation was sparse herb and shrub tundra, with Salix herbacea and open-ground species, followed by the development of a denser and m

External and internal factors influencing self-directed online learning of physiotherapy undergraduate students in Sweden: a qualitative study.

Online courses have become common in health sciences education. This learning environment can be designed using different approaches to support student learning. To further develop online environment, it is important to understand how students perceive working and learning online. The aim of this study is to identify aspects influencing students' learning processes and their adaptation to self-dir

Factors influencing insulin sensitivity in patients with mild primary hyperparathyroidism before and after parathyroidectomy

Objectives. Primary hyperparathyroidism (PHPT) is associated with cardiovascular disease. The aims of this study were to investigate lipid and glucose metabolism in mild PHPT, and to identify whether insulin sensitivity correlates with circulating levels of adiponectin, SHBG, and osteocalcin before and after parathyroidectomy (PTX). Materials and methods. Forty-five patients with PHPT were examine

Neural dynamics of inflectional and derivational processing in spoken word comprehension: laterality and automaticity

Rapid and automatic processing of grammatical complexity is argued to take place during speech comprehension, engaging a left-lateralized fronto-temporal language network. Here we address how neural activity in these regions is modulated by the grammatical properties of spoken words. We used combined magneto- and electroencephalography to delineate the spatiotemporal patterns of activity that supp

Incidence and Survival Analyses in Children with Solid Tumours Diagnosed in Sweden 1983-2007.

Aim: Solid tumours constitute 40% of childhood malignancies. The Swedish Childhood Cancer Registry is population-based and includes all children with cancer reported from the six paediatric oncology centres in Sweden. The aim was to investigate incidence and survival. Methods: We used the new WHO ICCC-3 for reclassification of the patients. Incidence and survival analyses were performed in the stu

Charge correlations using the balance function in Pb-Pb collisions at root s(NN)=2.76 TeV

In high-energy heavy-ion collisions, the correlations between the emitted particles can be used as a probe to gain insight into the charge creation mechanisms. In this Letter, we report the first results of such studies using the electric charge balance function in the relative pseudorapidity (Delta eta) and azimuthal angle (Delta phi) in Pb-Pb collisions at root s(NN) = 2.76 TeV with the ALICE de
