Yang, Z. (author), Li, Z. (author), Dollevoet, R.P.B.J. (author)This paper presents a full finite element (FE) interaction model of wheel-track to study the wheel-rail impact noise caused by squat. The wheel, the rail and some other track components are modeled with finite elements in three dimensions, where necessary and appropriate. Realistic contact geometry, including geometric irregularity (squat) in...conference paper 2013

Li, Z. (author)Authorship verification is one subfield of authorship analysis. However, the majority of the research in the field of authorship analysis is on the authorship identification problem. The authorship verification problem has received less attention than the authorship identification problem. Thus, there is a demand for a study on the authorship...master thesis 2013

Wang, H. (author), Li, Q. (author), D'Agostino, G. (author), Havlin, S. (author), Stanley, H.E. (author), Van Mieghem, P. (author)Most real-world networks are not isolated. In order to function fully, they are interconnected with other networks, and this interconnection influences their dynamic processes. For example, when the spread of a disease involves two species, the dynamics of the spread within each species (the contact network) differs from that of the spread...journal article 2013

Li, R. (author)PostNL Parcels (PNP) is the market leader in the Dutch domestic parcels market. This booming market is growing with almost 11% per year in revenue. PNP can keep up with this trend due to shipment volumes provided by its larger business senders belonging to the Key Account Managers. However, with the middle and smaller business senders PNP is...master thesis 2013

Nayak, A.R. (author), Li, C. (author), Kiani, B. (author), Katz, J. (author)A submersible PIV system has been deployed to characterize mean flow and turbulence in the inner part of the coastal ocean bottom boundary layer (BBL), and their interaction with the bottom roughness. Five large datasets, each consisting of ~20,000 velocity distributions, are chosen for analysis to represent flow conditions spanning a range of...conference paper 2013

Tsaoulidis, D. (author), Li, Q. (author), Angeli, P. (author)The hydrodynamic characteristics of liquid-liquid segmented flow in small channels were studied using bright field ?-PIV. Experiments were carried out in a 0.5 mm ID channel made of PFA and flow parameters key for mass transfer applications, such as film thickness, circulation patterns and plug length were measured. The two test liquids used...conference paper 2013

Li, M. (author), Van Keulen, W. (author), Ceylan, H. (author), Van de Ven, M.F.C. (author), Molenaar, A.A.A. (author)This paper investigates changes in tire/pavement noise caused by variations in the road surface characteristics. This research is based on the analysis of noise and surface characteristics collected from sections with 25 mm thickness thin layer surfacings in the Netherlands. Investigations are first performed on the measured noise levels in 1...journal article 2013

Li, S. (author)This is a personal graduation project under the studio of Complex Cities and Regional Planning in the spatial planning chair of Urbanism track in TUD. The motivation of exploring the theme as ‘Landscape into Urbanism’ comes from the increasingly emerging environmental risks globally in urban areas. As the medium between artificial urban...master thesis 2013

Li, W. (author), De Vriend, H.J. (author), Wang, Z. (author), Van Maren, D.S. (author)High-resolution morphological modeling of fluvial processes with complex, rapidly varying flows has been limited so far by model accuracy or computational efficiency. One of the most widely used numerical algorithms is based on the total variation diminishing method, solved by either upwind or centered approaches. An upwind scheme preserves high...journal article 2013

Fan, S. (author), Li, M. (author)Concrete cracking is inevitable, and can be the result of one or a combination of factors such as dry shrinkage, thermal contraction, fatigue, and embedded steel corrosion. The presence of cracks leads to further deterioration, service life reduction of concrete infrastructure, and frequent maintenance and repairs. These challenges can be...conference paper 2013

Shen, L. (author), Li, S.B. (author), Van der Zwaag, S. (author), Sloof, W.G. (author)The oxidation crack healing of Cr2AlC and Cr2(Al,Si)C was studied and compared with known healing of Ti2AlC. The oxidation induced crack healing of Ti2AlC is relatively fast and leads to full strength recovery, but the oxidation product contains besides ?-Al2O3 also undesired TiO2. However, when oxidizing Cr2AlC only ?-Al2O3 is formed, but full...conference paper 2013

(author)Crystalline solids are solid materials whose constituent atoms, molecules, or ions are arranged in a highly regulated fashion. Due to lack of rotational freedom in their stacking, they have been known as fragile materials. Even though some efforts have been dedicated to bind or mend defects/cracks in amorphous materials like concrete or polymers...conference paper 2013

(author)This paper investigates the needs or criteria for sustaining well-being in crowded situations through two focus group discussions with a total of ten participants. We conclude that pursuing crowd well-being could be divided into two different cases: one is obtaining the enhancement of the current state in normal situations, and the other is...conference paper 2013

(author)Within a virtual organization, more than one institution might be involved in the regulation of actors’ behavior. Each institution specifies a set of norms covering a specific aspect of the problem domain with a governance scope defining its remit. Together, they govern the participants and reflect the objectives of the organization. With actors...conference paper 2013

Li, Y. (author)Scale is an important parameter of images. Different objects or image structures (e.g. edges and corners) can appear at different scales and each is meaningful only over a limited range of scales. Multi-scale analysis has been widely used in image processing and computer vision, serving as the basis for many high-level image analysis systems....doctoral thesis 2013
