This paper compares all accident investigation reports covering railway accidents issued by the national investigation boards in Sweden, Norway and Denmark during a two-year period (2008-2009). By using content analysis, units of text describing attributed causes have been selected and categorized as belonging to one of three hierarchical levels; the micro level (technical malfunctioning and human

The paper presents two recently developed, Matlab-based analysis tools for realtime control systems. The first tool, called Jitterbug, is used to compute a performance criterion for a control loop under various timing conditions. The tool makes it easy to quickly judge how sensitive a controller is to implementation effects such as slow sampling, delays, jitter, etc. The second tool, called TrueTi

An increasing number of people today live with chronic diseases that affect their quality of life and that of their families. Health professionals confirm this finding based on their clinical interventions targeting families of chronically ill patients. The aim of this study was to describe and evaluate these interventions.

Biological nutrient removal processes for municipal wastewaters have received quite some attention during the past decades, especially due to the introduction of stricter legislation with respect to allowable effluent pollutant discharge limits. The necessity for performance improvement of existing activated sludge wastewater treatment plants (ASWWTPs) has created a need for detailed process model
