A plane wave impinges on a laterally double-periodic inhomogeneous lossy dielectric structure. Using a wave splitting approach, and an expansion of the fields and permittivity in entire domain basis functions, the scattered fields are determined via a propagator. The formulation is originally intended for constitutive parameters which vary continuously but is here applied to structures with an abr
Online sports betting is a billion-dollar industry with fierce competition to deliver the best possible experience. To be able to withstand the competition from rivals, bookmakers needs to be able to differentiate themselves with innovative and cutting edge solutions that offers a complete user experience. The goal of this master thesis is to investigate how sportsbook users perceive current betti
We present a comprehensive study of the concentration-induced growth of nonionic wormlike micelles in dilute solutions, below the overlap concentration, where we combine static and dynamic light scattering and NMR self-diffusion. The data are analyzed in detail in terms of the number-averaged contour length, assuming an exponential size distribution, as predicted by theory, and that the micellar f
Radiative lifetimes of 17 high-lying excited states in Rh I aremeasured using the time-resolved laser-induced fluorescence method. Out of these lifetimes, 13 are new and the remaining four confirm previous measurements. Furthermore, we report the first theoretical investigation of Rh I, where the radiative decay properties of all experimentally known levels below 47 000 cm(-1) are calculated using
How people react to a fire alarm has been studied in retrospect as well as in experiments. In the present study, the choice of exit was examined with respect to the distance to exits and open or closed emergency exit. The second part deals with some communication aspects regarding identification of signs. It is shown that the subjects prefer a familiar ordinary cash exit even if the distance to th
A fully integrated 1 V CMOS Bluetooth front-end for low IF has been designed and measured. The front-end consists of a common-gate LNA and a passive mixer and fulfils the requirements of the Bluetooth specification 1.0B. The front-end has a maximum signal headroom in all nodes since no transistors are stacked, and no external components are needed for the input matching. The measurements show a ve

Popular Abstract in Swedish Arbetslivet är en av de viktigaste delarna i människors livssituation och ett av de viktigaste incitamenten för välfärden i ett samhälle. Stora förändringar har skett för ungdomar beträffande arbetslivet och inträdet i arbetslivet under de senaste decennierna. Bl.a. de stora förändringarna gör att ny kunskap krävs för att ge möjlighet att stärka ungdomarna i deras inträThe aim was to gain knowledge of experiences of unemployment in young adults with special regard to quality of life (QOL) and to highlight work attitudes and related factors among adolescents. Three studies were performed in Kristianstad municipality, Sweden. In Study 1, a questionnaire was sent in 1998 to 264 unemployed young adults (md=22 years, range 20?25) and to a control group of 528 random
The great development of the food industry in the last few years and the increase of the global food trade have highlighted the importance of developing reliable safety assessment and the establishment of strict directives in order to assure its correct performance and the security of consumers. In this sense, the application of nanotechnology has played an important role to carry out very sensiti
We describe a new method for gas flux measurements that is a combination of differential absorption lidar (DIAL) and wind videography. The wind speed was measured by an imaging method that calculates the horizontal displacement of the plume with cross-correlation techniques. High spatial and temporal resolution is achieved with histogram equalization and window-filtering techniques. Simultaneous m
A new two-state polymer folding model is proposed, in which the folding of a stiff helical polymer is enabled by allowing for short sequences of coils connecting shorter and separated helices. The folding is driven by short-range attraction energy among stacked helices and is opposed by the free-energy cost of forming coils from helical monomers. Principal outcomes of the model are equilibrium dis
A drawback when hobbing lead crowned helical gears is that the gear tooth will be manufactured with alignment errors, often denoted flank twist. Together with other source deviations, these errors must not exceed the predetermined tolerances if the gear is to be finished hobbed. A simulation model is developed where the hobbing process can be analysed without additional errors resulting from real
Vibrationally resolved C1s photoelectron spectra of benzene and d(6)-benzene have been recorded using monochromated synchrotron radiation at photon energies of 330 eV. The spectrum of normal benzene displays considerable vibrational structure. Particularly noteworthy is the strong excitation of a combined CCH-bending and CC-stretching mode which splits the main peak into two well-defined maxima. I
