On the Possibilities of Detecting Surface Charges with Second Harmonic Generation and Optical Diagnostics of Polymeric Insulators

Optical second-harmonic generation can be a sensitive probe of atoms and molecules at a surface or interface. For this reason, the method was chosen to study surface charges. Our measurements have been limited by large fluctuations in the frequency-doubled light and the mean value of the signals did not give any consistent changes due to changes in the surface charge. A solid metal constituted the

Coordinate representations for rigid parts in multibody dynamics

The paper is concerned with coordinate representations for rigid parts in multibody dynamics. The discussion is based on the general theory of the dynamics of multibody systems under constraints. General configuration coordinates are introduced and the requirement of their regularity is discussed. The use of Euler angles, quaternions and linear coordinates, where quaternions and linear coordinates

MIMO Encoder and Decoder Design for Signal Estimation

We study the joint design of optimal linear MIMO encoders and decoders for filtering and transmission of a vector- valued signal over parallel Gaussian channels subject to a real- time constraint. The objective is to minimize the sum of the estimation error variances at the receiving end. The design problem is nonconvex, but it is shown that a global optimum can be found by solving a related two-s

Social Science Research on technology and the Elderly - does it exist?

Background: Despite the fact that old people´s technological needs have been payed much attention to in the last decennium, especially old users of information- and communication technology, technology has not found its natural place in research on ageing in modern societies. Purpose: This article examines to what extent social science research exist in the field of ageing and technology and where

Two-year outcome of Galantamine treatment in Alzheimer’s disease in a routine clinical setting.

Objectives: To describe and evaluate the two-year outcome on cognition (MMSE, ADAS-cog) and global rating (CIBIC) of galantamine treatment in Alzheimer’s disease (AD) in a routine clinical setting. Methods: The Swedish Alzheimer Treatment Study (SATS) is an open, longitudinal, multicenter study evaluating cholinesterase inhibitor (ChEI) treatment in AD. Patients are investigated at baseline, at 2

Att göra skillnad: Maskuliniteter i den internationella humanitärrätten och ICRC:s film ”International Humanitarian Law: A Universal Code"

Abstract in Undetermined I detta paper analyserar jag maskuliniteter i relation till den internationella humanitärättens (IHL) materiella innehåll som sådant samt i relation till ICRC:s tolkning och framställning av IHL i filmen ”International humanitarian law: A universal code”. Analysen utgår från Connells Masculinities, Pettmans Worlding Women, samt antar ett intersektionellt perspektiv i analy
