Artificial neural networks classify myocardial perfusion images

Popular Abstract in Swedish Populärvetenskaplig sammanfattning på svenska Datortolkning av myokardscintigrafibilder Kärlkramp och hjärtinfarkt sammanfattas ibland under benämningen ischemisk hjärtsjukdom, en vanligt förekommande sjukdom i många industriländer. Sjukdomen beror främst på förträngningar i hjärtats kranskärl, dvs. de kärl som förser hjärtmuskulaturen med blod. Sjukdomen går att behaIn the studies of this thesis, a method for automated classification of myocardial perfusion images was successfully developed and evaluated. The results show that the method, based on artificial neural networks, was equally good, or even better than human experts. It was also found that physicians interpreting myocardial perfusion images benefit from the advice of the artificial neural networks.

The Great Trajanic Frieze. The Study of a Monument and of the Mechanisms of Message Transmission in Roman Art

The Great Trajanic Frieze is a Monument firmly entranched in the tradition of Graeco-Roman art.The study of the different components of its imagery, such as composition, iconography and antiquarian details, reveals how it transmits and transforms this tradition. The imagery reveals itself as conscentiously structured to present and repeat a limited set of concepts to the viewer. The book also pres

NMR Diffusion Studies of Association in Surfactant Systems Inclusion Complexes, Micellar Solutions and Microemulsions

The aim of this thesis has been to investigate self-diffusion behavior of host-guest complex, microemulsion and polymer solution. Pulsed Field Gradient NMR (PFG-NMR) was shown to provide detailed molecular information in all system studied. The general strategy was to measyre the diffusivities of the species and from there get molecular insight into the aggregation and dynamics of the system.

Rheology of building materials

This document is a survey of the longterm deformations of building materials. A description of these deformations, common to all the materials, is given. The following materials are considered: concrete, cellular concrete, wood, fìberboard, partícle board, plywood, and to a lesser extent polymers and aluminium. The influences of time, stress, temperature and moisture are discussed.

Psykoterapi mot migrän

Abstract in Undetermined Resultat visar att aga och känslokyla hade förekommit i större utsträckning i migränikernas uppväxtmiljö, skriver Bertil Persson, Psykologiska institutionen i Lund, apropå sin avhandling om genetiskt inflytande, uppväxtförhållanden och personlighet i migränfamiljen.

Tigern som tolkar. Konfrontationer i Gustaf Wingrens teologi med särskild hänsyn till teologins uppgift inom universitet, samhälle och kyrka

Popular Abstract in Swedish I inledningen till detta arbete ställer jag några frågor, såsom vilka filosofiska och teologiska förutsättningar som påverkar Wingrens teologi, om han är medveten om dessa och är kritisk till dem. Detta är viktigt eftersom huvudsyftet med avhandlingen är att spåra de grundläggande tankeförutsättningarna hos honom. Wingren själv anser att tron är förutsättning för det teThe purpose of this study is to represent and critically analyse the theology of the Swedish theologian and professor in Lund, Gustaf Wingren (1910-2000), with special reference to his confrontational views on the role of theology at the university, in society and in church. The Lundensian school was famous for demonstrating a strictly scientific character of theology as an objective argumentation

Performance of heat exchangers using nanofluids

Heat exchangers are equipments being used for transfer of heat between two or more fluids at different temperatures (Sundén 2012). They are widely used in various fields, including power plants, automotives, space heating, refrigeration and air-conditioning systems, chemical plants, petrochemical processes, electronic cooling, and environment engineering. Many heat transfer enhancement techniques
