Finite scale homogenization of periodic bianisotropic structures
Texture compression of light maps using smooth profile functions
Light maps have long been a popular technique for visually rich real-time rendering in games. They typically contain smooth color gradients which current low bit rate texture compression techniques, such as DXT1 and ETC2, do not handle well. The application writer must therefore choose between doubling the bit rate by choosing a codec such as BC7, or accept the compression artifacts, neither of wh

Principles and nomenclature for the quantification of light
This chapter does not deal with any practical aspects of light measurement, only with theoretical concepts. The following concepts are explained: energy fluence, energy fluence rate, photon fluence, photon fluence rate, radiance and mol, as well as the following superfluous or obsolete terms and synonyms: actinic flux, space irradiance, scalar irradiance, spherical irradiance, vectorial irradiance
Interwar Film Culture in Sweden : Avant-Garde Transactions in the Emergent Welfare State
A survey over Swedish film culture between the world wars, focused on the connections between avant-garde filmmakers and cinephiles in the work for an institutionalised film culture (film archives, film journals, film schools etc.)
Improving Ethanol Production from Lignocellulose Hydrolyzates: Fed-batch Fermentation, Yeast Cultivation and Strain Development for Increased Tolerance
Ethanol production by the yeast Saccharomyces cerevisiae from dilute acid lignocellulose hydrolyzate was studied with the aim to improve fuel ethanol production. Specifically, the problem of inhibition was addressed. Lignocellulose hydrolyzate contains not only sugars, but also several compounds, such as furfural and 5-hydroxymethyl furfural (HMF), which can inhibit yeast growth and ethanol produc
Tool Life and Wear Model in Metal Cutting, Part 1 - Influence of Varying Flank Wear Criterion on Colding's Tool Life Equation
The tool life model formulated by Bertil Colding is limited to the use of a specified tool life criterion. The Colding equation describes the relationship between tool life, cutting speed and the equivalent chip thickness. The Colding equation is based on five constants which have unique values for each selected value of the tool life criterion. This paper investigates how these Colding constants
Eldens återsken : Första världskriget i svensk föreställningsvärld
Reflections of Fire. Images of the First World War in Sweden This thesis investigates the cultural impact of the First World War in Sweden, and how it shaped Swedish images and narratives about war and neutrality from 1914 to 1935. In line with Paul Fussell, George L. Mosse, and Jay Winter, among others, I discuss the symbolic, discursive aspects of the war at a popular, everyday level. The theor

Always on the wing - Fluid dynamics, flight performance and flight behavior of common swifts
The aerodynamics and kinematics behind the flight of animals are relatively unknown. Although animal flight has been studied for several hundreds of years, it is only in recent time that we have the technical abilities to study the mechanistic basis of animal flight. This thesis represents an attempt to widen the knowledge about animal flight by studying one of the most advanced flyers of the natu

Process control of an Open Plate Reactor
A new chemical reactor, the Open Plate Reactor, is being developed by Alfa Laval AB. It combines good mixing with high heat transfer capacity. With the new concept, highly exothermic reactions can be produced using more concentrated reactants. In the paper, the reactor type is presented and a process control system is developed.A utility system to provide the reactor with cooling water is designed

MeV Protons for the Characterization of Aerosols in Work Environments
In this paper the advantages of accelerator-based chemical analysis of work environment aerosols are discussed. Use of the PIXE method is central, but in order to take full advantage of the possibilities of an accelerator laboratory, it should be combined with nuclear methods such as particle-induced nuclear reactions and/or particle scattering for simultaneous measurements of light elements. It i
Att återskapa det förflutna - mellan kunskap och upplevelse
This text shows how the use of archaeological evicence in reconstructing the past give different views of each period in the past, from the Stone Age to the Middle Ages. Reconstructing the past is an adventure based on both knowledge and experience.
