Next generation wireless systems have to be able to efficiently deal with fast fading environments in order to achieve high spectral efficiency. Using multiple-input multiple-output (MIMO) systems and exploiting receive diversity, their spectral efficiency can be greatly increased. Commonly, the channel is estimated via training symbols, before the data detection is carried out based on the previo

Small scale embedded systems and sensors have become a booming research area over the past few years. One of the primary concerns regarding such systems is small scale and efficient code to facilitate small memory footprint requirements and low power consumption. In the communications sector there has been considerable effort put into reducing the scale of protocol stacks and making them more powe

Grade changes in polyethylene reactors, i.e., changes of operating conditions, are performed on a regular basis to adapt to market demands. In this paper, a dynamic optimization procedure is presented built upon the Modelica language extended with Optimica constructs for formulation of optimization problems. A Modelica library for the Borstar R multistage polyethylene reactors at Borealis AB, cons

The project “Arson - a societal problem” has been running with funding from a number of players since 2008. The project consists of a number of sub-projects and the work presented in this report was conducted within the sub-project: "Technical- and risk-based methods to prevent and mitigate the consequences of arson". The goal and purpose of the project was to develop and evaluate technical system

The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. Attention has also been devoted to the quest for sustainability within the field of chemistry. The concept of “green chemistry” is being intro

This paper deals with unequal error protection for code symbols of convo-lutional codes. The unequal error protection can be achieved due to different distanceproperties of output sequences and is sometimes described in terms of the correspondingeffective free distances. However, in many situations the effective free distance does notprovide enough information on the error-correcting capability. W

Jag har analyserat grundkursen i Patobiologi på termin 4 inom Läkarprogrammet som grund för pedagogisk utvecklingsplan. Kursen ges i både Lund (LÄLA42) och Malmö (LÄMA42) och har gemensam kursplan, identiska mål och kriterier för examination. Kursens syfte är att ge studenterna goda och relevanta kunskaper samt färdigheter i patobiologi, men ger även undervisning i laboratoriemedicinsk diagnostik

Two modeling approaches for a multi-cylinder cardboard dryer were compared with respect to fitting parameters and model structure. Model 1 includes internal mass transfer while model 2 does not. One important fitting parameter for all models is the contact heat transfer coefficient between the cylinder and the paper. Two different correlations, a constant value and a moisture dependant (linear) he
