In this contribution, we estimate the spatial diversity order and spatial correlations from channel sounder measurements of doubly-selective vehicle-to-vehicle MIMO radio channels in the 5.2 GHz band. Ivrlac and Nossek [1] have defined a diversity measure for MIMO Rayleigh fading channels which is based on the spatial correlations of the channel. Subsequently, Nabar et al. [2] have shown the exist

Popular Abstract in Swedish Tillgången på energi har varit av stor betydelse för utvecklingen av det det moderna industrisamhället. Samtidigt skapar energianvändningen ett flertal miljöproblem med lokal, regional och global utbredning. Syftet med denna avhandling är att studera olika strategier för att minska miljöpåverkan från det svenska energisystemet och bedöma strategiernas tekniska och ekonoEnergy use accounts for the dominating fraction of total sulphur dioxide (SO2), nitrogen oxide (NOx), volatile organic compounds (VOCs) and carbon dioxide (CO2) emissions. In this thesis, different strategies for reducing these emissions are evaluated, using a bottom-up approach. The thesis is divided in two parts. Part I (two articles) deals with how energy efficiency improvements and the increas

In this paper, we argue that, in addition to non-agreeing passives, Finnish has even an agreeing passive. The agreeing passive shows similar behaviour to non-canonical passives in other languages, such as get-passives in English. The agreeing passive differs from ordinary copular constructions in various ways, most importantly in the availability of an event-interpretation. Agreeing and non-agreei

In logistics, transport purchasers are increasingly facing environmental challenges. The role of logistics managers is important because their decisions as to how and where resources are used can potentially have major impacts on the environment. The challenge for logistics managers is to determine how to incorporate environmental management principles into their daily decision-making processes. 1

Understanding spatial and temporal variability in the distribution of seabirds is fundamental for the conservation and management of marine ecosystems. In the absence of large-scale systematic survey data, the application of standard habitat modelling techniques to predict the at-sea distributions of seabirds at large spatial scales has been limited. In this study, we examine the utility of relati

Many attempts have been made to catch the essence of Joseph Conrad’s work by examining the contents of his ideas. This thesis argues instead that the important factor is the preferred spatial structures of his world-views and the interplay between them. Above all, Conrad’s work can be seen as a battle-ground between closing and opening structures. The former have a claustrophobic effect on the con
