A classical solution for matching two image patches is to use the cross-correlation coefficient. This works well if there is a lot of structure within the patches, but not so well if the patches are close to uniform. This means that some patches are matched with more confidence than others. By estimating this uncertainty, more weight can be put on the confident matches than those that are more unc
OBJECTIVES: To examine whether the decrease in IMT progression rate in the carotid bulb induced by metoprolol CR/XL treatment (25mg once daily) observed in the β-blocker Cholesterol-lowering Asymptomatic Plaque Study (BCAPS) was accompanied by an effect on carotid plaque echogenicity. METHODS: Gray scale median (GSM) in carotid plaques, used as a score of echogenicity, was measured at baseline and
BACKGROUND: /st>Previous research suggests that the World Health Organization Surgical Safety Checklist time-out reduces communication failures and medical complications and supports development of better safety attitudes. Previous research also indicates that different values can affect the implementation of interventions. OBJECTIVE: /st>To investigate the actual usage of the checklist in practic
A high intake of omega-3 polyunsaturated fatty acids (ω-3 PUFAs), has been associated with reduced levels of blood pressure (BP). Their antihypertensive action may be due to the reduction of the ω-6/ω-3 ratio and the resulting competitive effect of ω-3 as compared to arachidonic acid (an ω-6 PUFA) as a substrate of cytochrome P450 (CYP450) enzymes involved in the production of vasoactive mediators
Integrated models including optics, structures, control systems, and disturbances are important design tools for Extremely Large Telescopes (ELTs). An integrated model has keen formulated for the European ELT and it includes telescope structure, main servos, primary mirror segment control system, wind, optics, wavefront sensor, deformable mirror, and an AO reconstructor and controller. There are t
Popular Abstract in English This work is focused on two accident types: accidents between motorized vehicles and pedestrians, and accidents between motorized vehicles and bicyclists. It aims at better understanding how the number of accidents is related to the number of road users; and how the speed at the site and age of the victim is related to how severe the injuries are. The work relies on sevThe aims of this work are to better understand (1) the relation between exposure and the risk of an accident between pedestrians and motorized vehicles and between bicyclists and motorized vehicles occurring at urban intersections and (2) how the speed environment and the victim´s age relate to the injury severity/outcome once a pedestrian or a bicyclist has been struck by a motorized vehicle. Cro
The paper examines and illustrates different trends in relation to historical energy use-related intensities and corresponding CO2 emission trends. The methodology encompasses a decomposition quantitative approach for estimating decoupling trends to energy use and economic and demographic parameters driving CO2 emission levels. The analysis covers both global and regional trends for the period 197
Popular Abstract in English The Andean region and the Amazon Basin of South America have been identified as regions of origin and the domestication of many plants. Some of the food crops from these regions such as potato and cassava, have gained global import¬ance, while the majority of food crops are hardly know outside their present area of cultivation. In the first part of this study, underutiBoth the nutritional and functional properties of starch are directly influenced by the molecular structure of its polymers: amylose and amylopectin. It is therefore important to have reproducible methods for quantifying the molecular size. In the first part of the thesis, the composition, crystallinity, degree of branching, morphological, thermal and pasting properties, and susceptibility of the
I kapitlet problematiseras den sociala rättigheten till skolutbildning på gymnasial nivå i Sverige med fokus på yrkes- och lärlingsutbildning utifrån ett medborgarskapsperspektiv. Syftet är att analysera hur ungdomarnas sociala rättighet till gymnasial utbildning förverkligas av statliga och kommunala aktörer. Jag avgränsar mig till att studera hur skolrepresentanter och tjänstemän på lokal nivå,
If we admit that, with the exception of language, human perception is predominantly visual, it is reasonable to think that all phenomena conveyed by the visual senses have something in common, but then visual semiotics/visual culture will comprehend much more than painting, sculpture, and architecture. The double coding hypotheses of cognitive psychology, as well as Lessing’s classical opposition
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul
This case-control study of tobacco smoking and acute myeloid leukemia (AML), emphasizing specific associations with morphologic and cytogenetic subtypes, comprised smoking histories for 333 cases and 351 controls. Smoking status (ever smokers versus life-long non-smokers) showed no evident effect on AML risk. However, an effect of smoking was indicated at high cumulative smoking doses (pack-years)
The European Union has initiated a number of initiatives to improve resource efficiency in Europe. The Ecodesign Directive is one of the policy instruments that could aid the transition towards a more resource efficient economy. So far, the Directive has mainly been applied to set requirements related to energy efficiency, but there is potential for setting legal standards that increase product du
In his recent work, Eco abandons his conventionalist theory of pictures, which was heavily censored by, among others, the present author. In so doing, however, Eco now goes to the other extreme, claiming that television images are like mirrors, which are no signs. It is my contention that Eco fails to come up with a more acceptable theory of iconicity. Since Eco is one of the few semioticians conc
The paper examines the reception of and revisions made to the teachings of the Italian astrologer-monk Placido de Titi (1603 – 1668) in Protestant England following the decline of astrology during the 18th century, particularly as found in the writings of John Worsdale (1766 – c. 1826), whose role in the emergence of modern astrology is to a certain extent reappraised, and of his contemporary crit
