Two new kinds of fractional-rate trellis source codes based on linear congruential recursions are evaluated. Properties of good codes are given. Square error distortion is similar to or better than competing schemes
Jämlikhet står inte i strid med variation och mångfald i samhället, utan är en garanti för att varje människa ges reella möjligheter att utveckla sin särart.
“Can an engineer, using a current simulation modelling programs, produce evacuation flow rates of a live emergency evacuation a priori to the analyses of the evacuation?” The above question is explored with reference to previous pre-evacuation modelling attempts and a new series of “small-scale” underground train evacuation experiments conducted under the METRO research project. METRO is concerne
Popular Abstract in Swedish År 2011 är det exakt 20 år sedan lärarkåren kommunaliserades. Reformen ger fortfarande upphov till diskussioner, inte minst från liberalt håll diskuteras idag lärarprofessionens status och vilka konsekvenser kommunaliseringen har medfört. I Professionens problematik analyseras motiven bakom kommunaliseringen. Historikern Johanna Ringarp visar att reformen var ett led i On 8 December 1989, the Swedish Parliament resolved that the state regulation of teaching positions would be terminated beginning on 1 January 1991. The parliament’s decision came on after fierce debates that took place in both teacher staff rooms and in public in 1989. Almost 20 years later, the reform still gives rise to controversy, and current political debates also touch on the possibility of
In this paper, a new algorithm that is able to identify and track multipath clusters in the delay-angular domain is introduced. The introduced algorithm avoids calculations of a single distance measure from quantities with different nature; instead it performs the clustering via extracting multiple 1D waveforms from the 2D delay-angular domain. The results from applying this algorithm to measured
This paper challenges one of the fundamental propositions within economic geography; that location in knowledge regions contributes to firm performance in general and especially for knowledge intensive firms that compete on the basis of knowledge. Our analysis of Swedish micro-data on 32,535 firms from 2004-2011 provides evidence that knowledge intensive firms benefit less from local knowledge spi
This paper discusses a computer-aided planning methodology and its applicability for planning of industrial production and working environments as well as for planning of residential and working environments for the differently abled. The methodology has been developed and evaluated in six case studies in mechanical industries and in six case studies related to adaptations for the differently able

Detectable debris discs are thought to require dynamical excitation (`stirring'), so that planetesimal collisions release large quantities of dust. We investigate the effects of the secular perturbations of a planet, which may lie at a significant distance from the planetesimal disc, to see if these perturbations can stir the disc, and if so over what time-scale. The secular perturbations cause or
