Abstract in UndeterminedThe machined subsurface often undergoes severe deformation and possible microstructure changes in a small scale subsurface layer. Mechanical behavior of this shallow layer is critical for component performance such as fatigue and wear, thus characterization of the mechanical behavior of the machined subsurface in terms of micro/nano hardness, modulus, residual stresses and

De ekonomiska effekterna av resfria möten (RM) har jämförts med en organisations omsättning och beräknas i snitt uppgå till: reducerat behov tjänsteresor: 1 procent; ökade IT-kostnader: 0,25 procent och insparad restid: 0,5 procent. Effekten av ökad effektivitet och flexibilitet för de anställda och för organisationen är mer svårbedömd; men den kan vara lika stor som de andra effekterna tillsamman

Popular Abstract in English Insects, birds, bats and pterosaurs have all evolved the ability to fly, even though it requires a lot of energy. The advantage is obvious: one can move about vertically, to go where others cannot, find and access distant food sources or escape your predators. But flying is also a very fast mode of transportation, and when you count the amount of energy required to get Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. To this end I studied the aerodynamic performance of a jackdaw (Corvus mone

X-ray diffraction methods have been used to study the crystal structure of different compounds, both organic and inorganic. The inorganic compounds were all synthesized by solid state reactions. A new compound, Re4As6S3, was synthesized and its structure was solved by Rietveld methods. Re4As6S3 is a cluster compound described by a rock-salt-type arrangement of ReAsS3- and As5- clusters. This stru

Esports is computer games played in a competitive environment, and analytics in this domain is focused on player and team behavior. Multiplayer Online Battle Arena (MOBA) games are among the most played digital games in the world. In these es, teams of players fight against each other in enclosed arena environs, with a complex gameplay focused on tactical combat. Here we present a technique for se

Popular Abstract in Swedish Denna avhandling är en s.k. sammanläggningsavhandling och innehåller tre delarbeten. Delarbete I är publicerat, delarbete II är under revision inför publikation och delarbete III är i manuskriptform. Syftet med mina studier har varit att undersöka regleringen av insulinsekretion från de insulinproducerande cellerna i bukspottkörteln med fokus på ett specifikt protein - Pancreatic beta-cell dysfunction and insulin resistance are the two hallmarks of type 2 diabetes. An early sign of beta-cell dysfunction is impaired nutrient-induced insulin release. Several insulin secretagogues act by increasing the formation of intracellular cAMP. Thus, accurate regulation of cAMP is of vital importance for the ability of the beta-cell to respond properly to these stimuli. The

Popular Abstract in Swedish Kontroll av fororeningar i dagens fusionsmaskiner aer ett inte alltfor stort problem. De kan dock anvandas for diagnostiskt syfte eftersom deras linjeemission avslojar ett flertal intressanta plasmaparametrar. For att kunna maeta egenskaper som jontemperatur, jondensitet och plasmarotation i ett fusionsplasma, aer det av yttersta vikt att den spektroskopiska tolkningen The spectrum and energy levels C IV and the 3l4l' system of the Mg-like ions in the iron group elements has been investigated. This has led to several hundred identified transitions, many of them previously unknown. Using the Charge Exchange diagnostic system at JET, ion temperatures, rotation velocities and densities have been derived from visible spectroscopic measurements on fully ionised light

The impact of European Union law on the regional and local levels in the Member States has been underestimated for a long time now. Today, however, it is clear that the impact of European Union law on these levels is important, not least as a consequence of the deregulation that has been carried out in most Member States in recent years. As local markets open up for competition, the scope of EU la

The purpose of this paper is to compare pension schemes with respect to their intergenerational redistributive effects caused by economic and demographic changes. It is shown how these effects depend on the specific design of the pension scheme, with special attention devoted to the indexation problem. There is a potential trade-off between financial stability of the pension system and a “desired”

Friction may be a major obstacle for stability and control performance. Based on a nominal control law, which stabilizes a nonlinear dynamical system to an equilibrium or to a desired limit cycle motion and which is derived without taking the friction disturbance into account, a method for compensating the impact of the friction is presented and stability analysis for the closed loop system is pre

This master thesis explores four television plays written and directed by Samuel Beckett: Eh Joe, Ghost Trio, ...but the clouds..., and Night and Dreams. The plays are read in accordance with the film-philosophical approach to cinema outlined in Gilles Deleuze's books on cinema. The master thesis attempts to position these plays as images in relation to the movement- and time-image as well as to t
