Two methods for visual evaluation of image quality of clinical radiographs have been compared. In visual grading analysis (VGA) specified anatomical structures in an image are visually compared with the same structures in a reference image, and in a free-response forced error (FFE) experiment - an extension of conventional ROC (receiver operating characteristics) analysis - the objective is to cor
Big Data analytics and Artificial Intelligence (AI) technologies have become the focus of recent research due to the large amount of data. Dimensionality reduction techniques are recognized as an important step in these analyses. The multidimensional nature of Quality of Experience (QoE) is based on a set of Influence Factors (IFs) whose dimensionality is preferable to be higher due to better QoE
Background: Many existing patient-reported outcome measures are extensive regarding both patient burden and administration, and in terms of analysing and reporting results. The VascuQoL-6 (VQ6) - a short version of the original Vascular Quality of Life Questionnaire (VascuQoL), a disease-specific instrument for peripheral arterial disease - was recently developed. However, the VQ6 has not yet been
Bathing water is of great concern as almost all bodies of water in Sweden today are affected by human activities. Usage of models for bathing water quality may give the possibility to assess and evaluate short-term contamination. The main objective of this thesis was to develop and evaluate a script for degradation of the faecal indicator bacteria Escherichia coli, E. coli, in an aquatic environme
This paper re-introduces the view on migration causes by the Austrian School of Economics. Austrian economics has not earned its fame in the field of migration, but rather on advocating libertarian economics. Nonetheless Mises outlined a migration model, which can be understood by adding some clarifications by Hayek. Given that the institutional barriers to migration raised by the state are remove
Parks, remnants of natural habitats and other green areas are important for preserving biodiversity in urban areas. Here, we investigate the relative importance of habitat type and connectivity for butterfly species richness in the city of Malmo, Sweden. Further, we compare species richness and composition in the urban habitats with that in the surrounding agricultural landscape using previously p
This paper deals with the quality aspects of e-learning courseware as seen by different quality stakeholders. In 2011, researchers and practitioners from more than 12 countries joined an initiative called “epprobate” with the aim of building a consensus on how to create a quality label and related consultative services for those who wish to enhance the educational value of their e-learning coursew
Fresh-cut fruit and vegetable are minimally processed products that have to maintain their quality (appearance, texture, flavour and nutritive value) similar to those of the fresh product. The fundamental principle underlying the quality of these commodities is that they are metabolic active tissues and, as a consequence, show physiological response to preparation procedures as well as to the envi
Objectives The main aim of this study was to evaluate the performance of 10 individual sensors of the same make, using objective measures of key image quality parameters. A further aim was to compare 8 brands of sensors. Study Design Ten new sensors of 8 different models from 6 manufacturers (i.e., 80 sensors) were included in the study. All sensors were exposed in a standardized way using an X-ra
Maternal smoking during pregnancy has been reported to negatively impact sperm counts of the sons. Sufficient data on the effect of paternal smoking is lacking.
Using the density of food left in a patch after foraging - i.e. the giving-up density (GUD) - as a behavioural indicator, short-term foraging studies on birds in the dry and wet fringing forests and savanna habitats of the Amurum Forest Reserve, Laminga, Nigeria, were used to evaluate whether widespread food abundance will affect their behaviour in these apparently-different habitats. The effect o
Stroke incidence in those of working age has been reported to be increasing significantly, implying strong incentives for research concerning working ability after stroke. This study focused on differences in subjective aspects of work and dimensions of quality of life after having experienced stroke. Sixty-five persons answered a postal questionnaire. The median age at the time of the stroke was
