Measurements and analysis of UWB channels in industrial environments

Communication in industrial environments is an important scenario for ultra wideband (UWB) systems. The characteristics of this environment differ considerably from office environments, where most of the channel measurements reported in the literature are performed. In this paper, we present the results and analysis of UWB channel measurements in an industrial environment. We investigate both peer

Cholesterol-lowering properties of oats: Effects of processing and the role of oat components

The cholesterol-lowering effect of oats has been studied for almost fifty years. The effect has hitherto essentially been associated with its content of β-glucans, the primary soluble dietary fibre in oats. Few studies have been published regarding the extent to which other oat components may contribute to the effect and how processing of oats may influence the cholesterol-lowering properties. The

The structure of the depots show that they mainly are collections of means of payment. It is demonstraded that the structure changes through time showing the development towards a monetarian economy

Automatic Tuning of Simple Regulators with Specifications on Phase and Amplitude Margins

The paper describes procedures for automatic tuning of regulators of the PID type to specifications on phase and amplitude margins. The key idea is a simple method for estimating the critical gain and the critical frequency. The procedure will automatically generate the appropriate test signal. The method is not sensitive to modelling errors and disturbances. It may be used for automatic tuning of

Innovations and social problem solving: A comparative study

This article explores the practical implementation of two innovative projects in Denmark and Sweden. The research is motivated by the high political interest for innovations as a modern quick fix to societal problems. Innovations are regarded as an all-round solution; however, research has mainly been focused on technical and economical factors without considering social problem solving. Utilizing

Robust Performance Optimization of Open Loop Type Problems Using Models From Standard Identification

This paper discusses the problem of finding the controller that optimizes the expected H2-norm for an uncertain system. The paper gives a unification of many similar results. The approach is motivated by the so called stochastic embedding approach. A closed form solution is given using a minimum of calculations for a class of problems including interesting signal processing applications such as fe

Transverse Instabilities in the MAX IV 3 GeV Ring

Collective effects in MAX IV 3 GeV storage ring are strongly enhanced by the combination of low emittance, high current and small effective aperture. Three passive harmonic cavities (HC) are introduced to lengthen the bunches, by which beam stabilization is anticipated via decoupling to high frequency wakes, along with Landau damping. The role of the transverse impedance budget of the MAX IV 3 GeV

Supply chain design and coordination in humanitarian logistics through clusters

Purpose of this paper: The cluster thinking in the humanitarian world has been suggested as a solution to the lack of coordinated disaster response in the past 10 years. Clusters on diverse functions including sheltering, logistics and water sanitation can be viewed as an effort of functional coordination, i.e. horizontal coordination within a functional area. The purpose of this paper is to contr
