This paper studies the effect of temporary speed restrictions (TSR) in railways. We present a method for analyzing the effect of TSR. TSR, or slow orders, are imposed on the railway to ensure safe use of the infrastructure. We have documented that TSRs give variations in the running times for trains...
The pioneering work of Mike Batzle and his colleagues has provided a fundamental understanding of mechanisms behind dispersion and attenuation of elastic waves in fluid-saturated rocks. It also has made way for a realization that these phenomena need to be accounted for in a better way when...
The objective of this review is to analyze the advances in risk analysis during the past 30 years and to offer an overview on its recent progress and applications for chemical and process industries. Although the general approach of quantitative risk assessment (QRA) remains unchanged since its...
