Fakta och fiktion gör bilder till vetenskapens verktyg

Bildens roll i vetenskapen har skiftat med synen på vad vetenskap är. Det fanns en tid då bara det konstnärliga geniet ansågs kapabel att fånga sanningen i bild. Mot slutet av 1700-talet var det i stället sparsmakade grafiska illustrationerna som gällde; estetik ansågs leda till subjektiv förvillelse och blockera vetenskaplig kunskap. Med dagens digitala bildteknik har den vetenskapliga illustrati

Dealing with Complexity in Knowledge Sharing Processes’

In a context of complex problem spaces, human individuals need support to carry out in-depth inquiry, generating many, diverse possibilities, without suffering from information overload. In earlier work, we have demonstrated the potential of a model of four-valued logic to provide support in a knowledge sharing environment by codifying, not knowledge, but categories of argument/assertion. In this

Laser-Based Cancer Diagnostics and Therapy - Tissue Optics considerations.

Near-IR light penetrates deeply into tissue, but as the scattering coefficient is much larger than the absorption coefficient in this wavelength region, direct viewing through tissue is very difficult. In order to detect and locate inhomogeneities located inside tissue a time-resolved technique was developed, based on gated viewing, i.e. detecting the first arriving photons with the shortest path

Sparse bayesian classification of predicate arguments

We present an application of Sparse Bayesian Learning to the task of semantic role labeling, and we demonstrate that this method produces smaller classifiers than the popular Support Vector approach. We describe the classification strategy and the features used by the classifier. In particular, the contribution of six parse tree path features is investigated.

"Complete" High-Spin Structure of 57Co

A comprehensive high-spin decay scheme has been deduced for 57Co using the Gammasphere Germanium detector array coupled to the 4π charged-particle detector system Microball. Following the fusion-evaporation reaction of 28Si(36Ar,1α3p)57Co at 136 MeV beam energy about 90 excited states have been observed in 57Co, which are connected by some 230 γ-ray transitions. The proposed level scheme reaches 1

Morphological and electromyographical studies of trapezius myalgia in cleaners

Popular Abstract in Swedish Sammanfattning på svenska Avhandlingen är en sammanläggningsavhandling, bestående av fem delarbeten. I avhandlingen studeras yrkesrelaterad muskelvärk (myalgi) i kappmuskeln (trapezius) ur framförallt morfologiska, histopatologiska och elektromyografiska aspekter hos en förhållande stor grupp av försökspersoner. Försökspersonerna består av städerskor med och utan yrkesrPathomechanisms of work-related myalgia are poorly understood. Myalgia is caused by exitation of nociceptors present in the muscular tissue but not in the muscle fibres themselves. Morphological analysis can contribute to knowledge of excitation of nociceptors. Surface EMG is a widely used method in the research field of ergonomics. Knowledge of influence of myalgia, occupation, age and intrinsic

Stochastic Modelling and Analysis of Sub-pixel Edge Detection

Stochastic analysis of edge detectors can be made either by theoretical modeling of the image formation process and the edge detectors or by empirical stochastic analysis of the edge locations. In this paper we study and model the image formation process in detail. In particular the much neglected discretisation process is modelled and taken into account. This makes it possible to define and analy
