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

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

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

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

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

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

The US EPA Method 1694 (which is specific to the analysis of pharmaceuticals and personal care products) was evaluated for analysis of selected hormones: 17a- and 17b-estradiol, estriol, estrone, 17a-ethynylestradiol, diethylstilbestrol, equilin, equilenin, testosterone, progesterone and norgestrel in filtered sewage influent/effluent and seawater. The extraction of hormones from fortified water m
