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

Jia, X. (author), Li, Y. (author), Xia, K. (author), Bauer, G.E.W. (author)Spin valves incorporating perpendicularly magnetized materials are promising structures for memory elements and high-frequency generators. We report the angular dependence of the spin-transfer torque in spin valves with perpendicular equilibrium magnetization computed by first-principles circuit theory and compare results with experiments by...journal article 2011

Li, Z. (author)In numerous radar applications, new problems concerning target detection in a clutter environment may occur. These problems cannot be solved using classical methods on the base of our current utilization of the reflection properties of various objects and their environment. Radar features that may assist in solving these problems are sought in...doctoral thesis 2011

Li, S. (author)Ultrafiltration (UF) is a proven technology in water treatment nowadays. However, fouling remains a major challenge in the operation of UF, especially in regard to colloidal NOM fouling. In general, a number of colloidal NOM fouling mechanisms may occur, such as adsorption, gel formation. Colloidal NOM fouling is influenced by multivalent...doctoral thesis 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

Mirzaee, H. (author), Li, L. (author), Ryan, J.K. (author), Kirby, R.M. (author)Theoretically and computationally, it is possible to demonstrate that the order of accuracy of a discontinuous Galerkin (DG) solution for linear hyperbolic equations can be improved from order $k$+1 to 2$k$+1 through the use of smoothness-increasing accuracy-conserving (SIAC) filtering. However, it is a computationally complex task to perform...journal article 2011

(author)A high-speed and hardware-only algorithm using a center of mass method has been proposed for single-detector fluorescence lifetime sensing applications. This algorithm is now implemented on a field programmable gate array to provide fast lifetime estimates from a 32 × 32 low dark count 0.13 ?m complementary metaloxide-semiconductor single-photon...journal article 2011

Li, S.J. (author), Shen, C. (author), Sarro, P.M. (author)This paper presents a silicon micromachined filter for micro- and nanoparticles. The filter is vertical and completely buried beneath the surface. The buried aspect allows additional features to be integrated above the filter, while the vertical aspect allows the creation of highly uniform pores and efficient use of die area. The filter is...journal article 2011

Van Mieghem, P. (author), Stevanovi?, D. (author), Kuipers, F. (author), Li, C. (author), Van de Bovenkamp, R. (author), Liu, D. (author), Wang, H. (author)The decrease of the spectral radius, an important characterizer of network dynamics, by removing links is investigated. The minimization of the spectral radius by removing m links is shown to be an NP-complete problem, which suggests considering heuristic strategies. Several greedy strategies are compared, and several bounds on the decrease of...journal article 2011

Minchin, E. (author), Li, X.X. (author)The traditional system of design-bid-build has long been the principal delivery system for horizontal construction; it has been employed by all the transportation departments in the United States for almost a century. The shift toward design-build (DB) as a time saving method has been successful in many ways, but use of the system has exposed...conference paper 2011

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
