We apply causal loop diagrams (CLD) to picture how complex societal scenarios can be understood in terms of interdependent drivers and mechanisms between actors from the public and private sectors respectively. And we show how un-sustainable scenarios can be understood in terms of insufficient balancing feed-back in the system. We apply the methodology to picture such imbalances as funda- mental d

Investigation of a novel condition monitoring approach, combining artificial neural network (ANN) with a sequential analysis technique, has been reported in this paper. For this purpose operational data from a Siemens SGT600 gas turbine has been employed for the training of an ANN model. This ANN model is subsequently used for the prediction of performance parameters of the gas turbine. Simulated

Sentiment analysis, or opinion mining, is the process of extracting sentiment from documents or sentences, where the expressed sentiment is typically categorized as positive, negative, or neutral. Many different techniques have been proposed. In this paper, we report the reimplementation of nine algorithms and their evaluation across four corpora to assess the sentiment at the sentence level. We e

We focus on improving resilience of cloud services (e.g., e-commerce website), when correlated or cascading failures lead to computing capacity shortage. We study how to extend the classical cloud service architecture composed of a load-balancer and replicas with a recently proposed self-adaptive paradigm called brownout. Such services are able to reduce their capacity requirements by degrading us

Our presentation will try to clarify the differences between Postphenomenology and Postpositivism. Contemporary studies of technology and its relation to science are very much inspired by the works of Don Ihde and Bruno Latour.Updated February 2016.

By applying Doppler-free saturated absorption spectroscopy in the regime of high integrated sample absorption, high-contrast Doppler-free laser transmission signals can be obtained as demonstrated in experiments on the sodium D lines. Natural linewidth background-free signals are observed.

This paper explores the evolution of Swedish fiscal policy from one extreme approach to another one in less than four decades. After the demise of the Bretton Woodssystem in the early 1970s, Swedish fiscal policy was based on a Keynesian approach with the goal to stabilize the business cycle and maintain full employment using a large set of instruments in a discretionary manner. In the wake of the

I bokens första studie, "Samhällsbyggarnas tv-undervisning. Estetik och ideologi i utbildningsprogram för televisionen" författad av Ann-Kristin Wallengren, ställs frågan om hur ett programs form och estetik är kopplat till samtidens samhällsbild och ideologier. Genom analyser av ett antal samhällskunskapsprogram för skolbarn visas hur utbildningsprogrammen från 1960-talet och framåt har förändrat

“The death of distance” has become the battle cry of a modern generation of managers, policy makers and scientists who embrace the new globalized economy and its promise of frictionless exchange across the world. While highly influential, this view does not, however, stand unchallenged. Over the last 15 years, there has been a growing interest in the geographical clustering of industry. Well-known
