(author), Charbon, E. (author), Henderson, R. (author), Arlt, J. (author)Fluorescence lifetime of dye molecules is a sensitive reporter on local microenvironment which is generally independent of fluorophores concentration and can be used as a means of discrimination between molecules with spectrally overlapping emission. It is therefore a potentially powerful multiplexed detection modality in biosensing but requires...journal article 2010

(author)Micro features with high aspect ratios are one of the commonly encountered geometries found in micro products. In the literature, these structures are often used in demonstrator products machined by a micromilling process. In this paper, the challenges in micromilling thin ribs ith high aspect ratios have been studied. Due to the scaling effect,...journal article 2010

Li, H. (author), Bliemer, M.C.J. (author), Bovy, P.H.L. (author)Stochastic supply and fluctuating travel demand lead to stochasticity in travel times and travel costs experienced by travelers from time to time within a day and at the same time from day to day. Many studies show that travel time un-reliability has significant impacts on traveler’s choice behavior under uncertainty. Different theories are...conference paper 2010

Arias-Cuevas, O. (author), Li, Z. (author), Lewis, R. (author)The adhesion (or available friction) in the wheel–rail contact is the most important parameter for the braking and traction operation of rail vehicles. Since the beginning of railway transportation, sanding from the locomotive has been a common practice to enhance the wheel–rail adhesion. In recent years, sanding from electrical multiple units ...journal article 2009
