The latency and amplitude of the midlatency auditive evoked potential's (AEP) Nb-trough has been found to indicate the depth of anaesthesis. The aim of this paper is to present a system that reliably estimates these parameters without a long time delay. The result shows that it is possible to estimate and track changes in latency and amplitude of the Nb-trough with a delay below 1 minute at a stim
Hur man beskriver och eftersträvar välbefinnande är viktigt, eftersom det påverkar både forskning och samhället i stort. Denna avhandling handlar om hur välbefinnande definieras och mäts, vilket både innefattar en kritisk diskussion kring befintliga teorier om välbefinnande samt en utveckling av empiriska metoder och statistiska verktyg för att öka vår förståelse gällande hur personer uppfattar ocHow to define and measure individuals’ well-being is important, as this has an impact on both research and society at large. This thesis concerns how to define and measure the self-reported well-being of individuals, which involves both theorizing as well as developing and applying empirical and statistical methods in order to gain a better understanding of well-being.The first paper critically re
The spectral characters of the electroencephalogram activity (EEG) is of interest both in studies of the EEG and in estimation oI Evoked Potentials. Often parametric methods assume an underlying model like AR or ARMA [1]. To avoid the model assumption a non-parametric multiple-window meihod for spectral estimation is used in this paper. The method uses Slepian's Discrete Prolate Spheroidal Wave Fu
An algorithm for estimation of event related signals dis-turbed by coloured noise, e.g. Evoked Potentials disturbed byEEG, has been investigated. The method is based on GeneralSingular Value Decomposition, GSVD, and estimates a singleEvoked Potential without averaging. There are no assumptionsabout the model for the EEG. The EP is described as a sum ofdamped sinusoids. The algorithm is tested with
A study is done concerning event related potentials in coloured noise, such as evoked potential signals (EP) in EEG. Two estimators, both based on the least square version of the Prony method, combined with singular value decomposition, have been investigated. The EP is described by a sum of damped sinusoids in both estimators. In the first estimator the noise is described by an ARMA—process and in
PurposeThe activities of academic researchers are increasingly regulated by neo-liberal ideals, including expectations that researchers are visible online and actively promote their output. The purpose of this paper is to explore how researchers take on this responsibility. It uses the concepts of genre, authorship and self-writing in order to understand how the story of an academic life is constr
Many analyses and debates developed in the last decades around trade unions’ revitalisation, pointing to different national traditions in the varieties of capitalism. Gender equality adds a new perspective to these debates, showing that women can be a crucial test for, and an instrument of, trade union revitalisation. In the current situation in Italy, what are the main challenges facing working w
The paper’s title evokes a conversation; in fact it has been constructed like a joint revisitation of Bianca Beccalli’s forty years work on labour, gender, and politics, reconsidering old challenges and facing emergent ones. The paper deals with two levels of analysis: a historical and sociological interpretation of social movements, work, and politics on the one side, while dealing on the other s
