In this paper we present analytical expressions for the angle-of-arrival (AOA) power density function (PDF) and its application in geometrically based channel models for urban environments. We make comparisons with experimental results for wideband channel models, published in the open literature, in order to evaluate the theoretical clusters PDF in angle domain proposed. The comparison with exper

Since year 2000 a number of national energy management systems (EnMS) standards and specifications have been developed. To support EnMS implementation in industry some governments have launched agreements centered around energy management practices. National experiences show that such policy programs can achieve significant energy efficiency improvements. Implementation of industrial EnMSs has gra

Popular Abstract in Swedish Anatomi och taxonomi för ca 125 cetrarioida lavar är undersökt. Gruppen består av släktet Cetraria (islandslavar) i vid bemärkelse. Speciell tonvikt har lagts på reproduktiva strukturer som sporsäckar och konidier. Cetrarioida lavar är speciellt vanliga i Sydostasien och Nordamerika, men finns företrädda även i Sverige. Avhandlingen består av 15 välillustrerade delpubliThe anatomy of the cetrarioid lichens (Parmeliaceae) has been studied, and the taxonomy revised. Special attention has been paid to reproductive structures, in particular the asci and pycnoconidia. Two types of asci are recognized. The Cetraria type is narrowly clavate, bears an amyloid ring structure in the tholus, and has a small axial body. The Lecanora type, specifically the Melanelia form, is

Many high spin rotational bands in superdeformed nuclei have been found in the A ~ 140-150 region, but so far no linking transitions to known normal-deformed states have been found in these nuclei. Therefore, configuration and spin assignments have to be based on indirect spectroscopic information. Identical bands were first discovered in this region of superdeformed shapes. At present, som

In this thesis, theoretical studies of the transport properties of three nanoscale systems: one-dimensional (1D) quantum wires (QWRs), zero-dimensional (0D), laterally confined, double-barrier resonant tunnelling structures (DBRTSs) and three-terminal ballistic junctions (TBJs), have been performed. In the first part of the thesis, an overview of the realization and properties of such systems is g

This article discusses the question if vowel harmony is an areal or genetic feature.

Sammanfattning Denna rapport handlar om tillväxt och kommunala strategier för att nå tillväxt. I rapporten görs en översikt över olika tillväxtbegrepp och hur kommuner kan välja att prioritera bland olika målsättningar. Dessutom görs en analys av vilka faktorer som påverkar utfallet av kommunernas arbete samt hur de kan agera strategiskt för att skapa tillväxt. Trots att kommuner i grunden kan

The supply of fresh food is being transformed: retailers are gaining increasing power and control from manufacturers and the location and nature of production is evolving. This new title, based on groundbreaking research, will enable logistics professionals to recognise the opportunities available in this changing market and successfully manage change in the supply chain. The international practi
