The present thesis focuses on the numerical simulation of the flowfield in gas turbine burners. Due to the higher and higher requirements regarding pollutant emissions there is a need for new combustion technologies. In gas turbines one method to obtain low pollutant levels is the use of lean premixed or partially premixed combustion. However, in lean combustion problems regarding the flame stabi

Water resources management in water scarce regions like the Southern Africa Development Community (SADC) is challenging with both large hydro-climatic-induced scarcity and the considerable inter-annual fluctuations at the centre of the allocation problem. Water must be allocated both in time and space using acceptable criteria and most importantly, all stakeholders must adhere to the decisions imp

The dissertation deals with the ideology of martyrdom of the Hebrew chronicles, written in response to the persecutions of the Jews in a number of German communities during the beginning of the First Crusade. Elements of this ideology is analysed in relation to earlier Jewish tradition as well as contemporary Christian theology of martyrdom

Popular Abstract in Swedish Nästa år är det 400 år sedan Galileo Galilei för första gången riktade ett teleskop mot objekt på himlen. Allt sedan dess har teleskopet varit det viktigaste instrumentet för astronomins utveckling och med dess hjälp har vår kunskap om universum revolutionerats. Tack vare utvecklingen av teleskopet under dessa århundraden har allt ljussvagare objekt kunnat studeras, ochThis thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. The aim of this project was to gain hands-on knowledge in the development of a real adaptive optics system and eventua

Coherent folded acoustic phonons in a multilayered GaSb/InAs epitaxial heterostructure were generated by femtosecond laser pulses and studied by means of ultrafast x-ray diffraction. Coherent phonons excited simultaneously in the fundamental acoustic branch and the first back-folded branch were detected. This represents the first clear evidence for phonon branch folding based directly on the atomi

This paper initially presents an introduction to the Swedish land administration system, particularly focusing on the parts of the Real Property Register that compose the cadastre. Here, a brief retrospect of the long tradition of land related registration follows by an account of the current components, functions and parties concerned. The second part of the paper then discusses a vision, express

Scanias motormonteringsverkstad i Södertälje använder sig av en motorpall för att internt hantera motorer. Motorpallen används även externt som transportemballage för motorleveranser tex. till Scanias slutmonteringsenheter. Motorpallen är anpassad till samtliga Scanias motorer och är tillverkad av stål. Scania uppskattar att totalt 2 500 motorpallar cirkulerar i det slutna flödet och att kostnaden

This paper presents a theory to quantify the informational value of human acts. We argue that living is functioning against entropy. Acting is presented as a set of decisions and choices to create order that we use as the foundation to develop the concept of complexity of human acts. Frequency theory of probability is then applied to characterize human acts in terms of their degree of freedom and
