However, the provenance of quartz-porphyry clasts in a Devonian conglomerate have also been investigated in northwestern Svalbard. This information is important for reconstructions of plate movements in the high Arctic during the Caledonian orogeny and earli

The SCR technique is used (1998) in five Swedish wood fired CHP plants. These plants are among the first references in the world for SCR in combination with bio fuels. The experiences show some problems with the catalyst function because of deactivation and ash-plugging. The deactivation has been handled by seasonal washing of the catalyst. In this work the cause for and the extent of catalyst dea

Liberalisation and deregulation of public utility sectors has been introduced in several European countries. In 1994 Swedish municipalities were instructed to reorganise waste collection routines by enlarging the number of fractions to be able to reuse waste fractions in an environmental benign way. The public waste sector have to a considerable extent been diversified and deregulated. At the same

Sex allocation is an important field in evolutionary biology, both historically and currently. However, while sex allocation theory has successfully predicted sex ratio bias in some taxa, most notably parasitic wasps, vertebrates are notorious for their poor fit to theoretical models. We argue that this arises from the use of very complex model systems to test relatively simple theoretical models.

Grundkurser vid LTH har ofta problemet att motivera studenten eftersom han/hon inte omedelbart kan koppla teorin till sin vardag eller till kommande profession. Ett väl dokumenterat sätt att synliggöra användning av kunskap är låta studenterna arbeta aktivt med realistiska problemställningar på en lagom nivå, t.ex. i projekt eller cases. I grundkursen i matematisk statistik för V och L använder vi

Recent literature presents methods for the analysis of concatenated coding schemes by solely characterizing the behavior of the component codes [4], [12], [16], [9], [7]. Component codes are analyzed either analytically using unique properties of special component codes, e.g., single-parity-check code or accumulator, or via simulations. The goals of this paper are to find fundamental insights into

In this paper we show that systematic convolutional encoders perform as well as nonsystematic ones when they are used together with M-algorithm decoders. We describe the algorithm and give a brief historical review.
