This paper presents a travel time model for multi-deep AS/RS, which determines the average travel times during a single command storage or retrieval and a dual command cycle. The model can determine the relocation probability, the number of expected relocations and the travel times in storage...

The PEM fuel cell model presented in this paper is based on modelling species transport and coupling electrochemical reactions to species transport in an innovative way. Species transport is modelled by obtaining a 2D analytic solution for species concentration distribution in the plane...

Some bias can occur when an increase in non-target-disease-specific mortality is not considered when modelling the outcomes of screening tests. </AbstractSection> Copyright Springer-Verlag Berlin Heidelberg 2013
