This paper presents the application of several optical measurement techniques for the characterization of the combustion behavior of the pilot burner of a gas turbine combustor developed according to the lean premixed prevaporized (LPP) concept. The vaporization of the kerosene fuel (Jet-A) and its consequent mixing with air has been visualized using combined Laser-Induced Fluorescence (LIF) and M
This thesis is a study of landownership that took place in Scania in southern Sweden in the 1860s. Basically it was a conflict between an alliance of tenant farmers and rural poor against estate owners in a time of agrarian change, a time characterized by mass evections of tenants and increasing proletarization. The participants of the movement, led by the self-taught lawyer Samuel Tullberg, claim

This thesis is divided in two parts, one that deals with the development of the new data acquisition system at Lund Nuclear Microprobe, and a second part that deals with different applications. A CAMAC based data acquisition system has been installed at the Lund Nuclear Microprobe facility. The system is a true multi-parameter and multi-detector system with fast FERA bus readout and in crate memor
Due to the increasing usage of embedded instruments in many electronic devices, new solutions to effectively access these instruments appeared, including the new IEEE 1687 standard. The approach supported by IEEE 1687 allows a flexible access to embedded instruments through the Boundary Scan interface. The IEEE 1687 network includes a set of reconfigurable scan chains. This paper addresses the iss
This talk describes the various stages of ATLAS Data Challenge 2 (DC2) in what concerns usage of resources deployed via NorduGrid's Advanced Resource Connector (ARC). It also describes the integration of these resources with the ATLAS production system using the Dulcinea executor. ATLAS Data Challenge 2 (DC2), run in 2004, was designed to be a step forward in the distributed data processing. In p
The problem of empty names derives from the fact that empty names fail to refer. The reference failure of empty names implies that sentences containing empty names lack truth-conditions. As a consequence those sentences are meaningless, according to many theories of meaning. The present dissertation addresses the problem of empty names and proposes a solution to the problem at hand. In brief, the
Structure from sound can be phrased as the problem of determining the position of a number of microphones and a number of sound sources given only the recorded sounds. In this paper we study minimal structure from sound problems in both TOA (time of arrival) and TDOA (time difference of arrival) settings with collinear constraints on e.g. the microphone positions. Three such minimal cases are anal
Background Variations in colonoscopy practice exist, which may be related to healthcare quality. Aims To determine factors associated with three performance indicators of colonoscopy: complete colonoscopy, adenomatous polyp diagnosis, and duration. Patients Consecutive patients referred for colonoscopy from 21 centres in 11 countries. Methods This prospective observational study used multiple
