Li, C. (author), Wang, H. (author), Van Mieghem, P. (author)The largest eigenvalue ? 1 of the adjacency matrix powerfully characterizes dynamic processes on networks, such as virus spread and synchronization. The minimization of the spectral radius by removing a set of links (or nodes) has been shown to be an NP-complete problem. So far, the best heuristic strategy is to remove links/nodes based on the...conference paper

Li, Z. (author), Arias Cuevas, O. (author)The adhesion level between wheel and rail has been since the beginning of railway a crucial parameter in the design and operation of rail vehicles. In the last decades, many railway organizations have suffered from low adhesion problems as consequence of the increased exploitation of the rail infrastructure. Leaves and water have been widely...conference paper 2009

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

Qian, S. (author), Li, V.C. (author), Zhou, J. (author)Strain hardening cementitious composites (SHCCs) have seen increasing field applications in past decade, yet existing quality control test methods for tensile properties are sometime difficult to implement. This paper presents a new simple inverse method for quality control of tensile strain capacity by conducting beam flexural test. It is shown...conference paper 2010

Oregui, M. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author), Moraal, J. (author)In railway tracks, short wave rail surface defects give rise to high wheel-rail dynamic forces and noise. Having a better insight into short wave defect occurrence could lead to development of adapted maintenance methods or track design to delay or avoid defect, so that the high short wave defect related maintenance costs may be reduced. As part...conference paper 2011

Cornelissen, H.J. (author), Ma, H. (author), Ho, C. (author), Li, M. (author), Mu, C. (author)A novel method is presented to inject the light of millimeter-sized high-brightness blue LEDs into light guides of submillimeter thickness. Use is made of an interference filter that is designed to pass only those modes that will propagate in the light guide by total internal reflection. Other modes are reflected back to the LED cavity and...conference paper 2011

Verhagen, A.A. (author), Teunissen, P.J.G. (author), Van der Marel, H. (author), Li, B. (author)A key issue with GNSS carrier phase ambiguity resolution is that often the full set of ambiguities cannot be fixed fast and reliably. A possible strategy is then to resolve only a subset of ambiguities, one for which the probability of correct fixing, the so-called success rate, is sufficiently close to 1. However, a proper subset selection...conference paper 2011

Ying, S. (author), Guo, R. (author), Li, L. (author), Van Oosterom, P.J.M. (author), Ledoux, H. (author), Stoter, J.E. (author)In this paper the design and development of a prototype 3D Cadastral system will be presented. The key aspects of this system are that the model is based on Land Administration Domain Model (LADM) and that the spatial profile is based on a full 3D topological structure. The prototype development starts with profiling the LADM (selecting relevant...conference paper 2011

Li, J. (author), Liu, X. (author), Scarpas, A. (author), Tzimiris, G. (author)In the Netherlands an asphaltic surfacing structure for orthotropic steel bridge decks mostly consists of two structural layers. The upper layer consists of Porous Asphalt (PA) because of reasons related to noise hindrance. For the lower layer a choice between Mastic Asphalt (MA) or Guss Asphalt (GA), can be made. In this paper, a typical Dutch...conference paper 2012

Oregui, M. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)Rail joints have a shorter service life than most other railway track components. The discontinuity between rail ends turns the rail joint into a weak spot, and consequently, into a track component demanding more frequent maintenance measures, which result in high maintenance costs. Moreover, difficulties are often found when assessing the...conference paper 2012
