An Impedance Tuning Unit (ITU) has the ability to tune the impedance of for instance the antenna to better match another impedance. To effectively characterize a circuit containing an ITU, several functions in a measurement system need to be remotely controlled. In this paper such a measurement system is described. A line tune screw creates impedances for the ITU to match and a digital acquisition
A bidirectional algorithm for computing spectral coefficients of convolutional and tailbiting codes is presented and used to obtain new codes.
Group A streptococci are common human pathogens that cause a variety of infections. They express M proteins which are important cell wall-bound type-specific virulence factors. We have found that a set of strains, associated primarily with skin infections, express M proteins that bind plasminogen and plasmin with high affinity. The binding is mediated by a 13-amino-acid internal repeated sequence
Popular Abstract in Swedish Många kemiska processer och reaktioner utspelas på ytan av material. Vissa fenomen, såsom korrosion, är uppenbara för blotta ögat, medan andra kan vara mindre uppenbara. Några saker som kanske inte direkt brukar associeras med ytor är katalytiska reaktioner (som oxidering av kolmonoxid, CO, till koldioxid, CO2), och elektriska egenskaper. Forskning på ytor kan, för att The work presented in this dissertation addresses two main topics: (i) graphene supported nanoparticles and their stability upon gas adsorption, and (ii) intercalation of different molecules under graphene and their reactions under graphene. From an interplay of X-ray photoelectron spectroscopy, scanning tunneling microscopy, low energy electron diffraction, and density functional theory an atomic
Abstract.Over the past decade, a new global regime of anti-corruption has taken shape. Pushed by NGOs such as Transparency International, and with coalitions of international organizations, Western governments, and private business circles, we now have a framework of conventions and regulations that impel governments and international firms to act with integrity and to prevent corruption in busine

Languages can be classified into three types, e.g. situation-oriented (e.g. Russian, Chienese, etc.), speaker-oriented (e.g. Bulgarian, Turkish, etc.) and hearer-oriented (e.g. English, Danish, etc.) (Durst-Anderssen 2005, 2006, 2008). In this paper, it is argued that the difference in spoken and written discourse can be compared to different patterns in these classificatory types, and historical
