Rothkrantz, L.J.M. (author), Fitrianie, S. (author)During major disaster events, human operators in a crisis center will be overloaded with under-stress a flood of phone calls. As an increasing number of people in and around big cities do not master the native language, the need for automated systems that automatically process the context and content of information about disaster situations from...conference paper 2015

Morales-Espana, G.A. (author), Gentile, C. (author), Ramos, A. (author)This paper provides the convex hull description for the basic operation of slow- and quick-start units in power-based unit commitment (UC) problems. The basic operating constraints that are modeled for both types of units are (1) generation limits and (2) minimum up and down times. Apart from this, the startup and shutdown processes are also...journal article 2015

Hwang, P.A. (author), Fois, F. (author)Ocean surface roughness and wave breaking are the two main contributors of radar backscattering from the ocean surface. The relative weightings of the two contributions vary with the microwave polarization: the VV (vertical transmit vertical receive) is dominated by the Bragg resonance scattering mechanism, and the HH (horizontal transmit...journal article 2015

De Lange, M.F. (author)A novel class of materials, i.e. Metal-Organic Frameworks (MOFs), has successfully been developed that is extremely suited for application in heat pumps and chillers. They have a superior performance over commercial sorbents and may potentially contribute to considerable energy savings worldwide. Globally about 33 % of the energy consumption is...doctoral thesis 2015

Zadpoor, A.A. (author)The relationship between hip deformities and osteoarthritis has recently received a lot of attention. In particular, it has been shown that both osteoarthritis and its precursors, such as the hip deformities that lead to femoroacetabular impingement (FAI), are more prevalent in elite athletes compared with the general population. However, the...journal article 2015

(author), Bonaldi, M. (author)We present an oscillating micromirror with mechanical quality factors Q up to 1.2×106 at cryogenic temperature and optical losses lower than 20 ppm. The device is specifically designed to ease the detection of ponderomotive squeezing (or, more generally, to produce a cavity quantum optomechanical system) at frequencies of about 100 kHz. The...journal article 2015

Mahapatra, P.S. (author)For the past two decades, interferometric synthetic aperture radar (InSAR) has been used to monitor ground deformation with subcentimetric precision from space. But the applicability of this technique is limited in regions with a low density of naturally-occurring phase-coherent radar targets, e.g. vegetated nonurbanized areas. Third-party end...doctoral thesis 2015

Dintzner, N.J.R. (author), Van Deursen, A. (author), Pinzger, M. (author)Evolving a large scale, highly variable system is a challenging task. For such a system, evolution operations often require to update consistently both their implementation and its feature model. In this context, the evolution of the feature model closely follows the evolution of the system. The purpose of this work is to show that fine-grained...journal article 2015

Zeilemaker, N.S.M. (author)P2P networks employ the resources available at peers to reduce the load at, or eliminate the need for a server. In order to achieve these goals, protocols are implemented which aim to allow peers to collaborate efficiently. However, these same protocols can make peers an easy target, as their willingness to collaborate can be susceptible to...doctoral thesis 2015

Bal, M. (author), Ansari, M.H. (author), Orgiazzi, J.L. (author), Lutchyn, R.M. (author), Lupascu, A. (author)We present experiments on the dynamics of a two-state parametric fluctuator in a superconducting flux qubit. In spectroscopic measurements, the fluctuator manifests itself as a doublet line. When the qubit is excited in resonance with one of the two doublet lines, the correlation of readout results exhibits an exponential time decay which...journal article 2015

Giepman, R.H.M. (author), Schrijer, F.F.J. (author), Van Oudheusden, B.W. (author)This study investigates the effects of boundary layer transition on an oblique shock wave reflection. The Mach number was 1.7, the unit Reynolds number was 35 × 106 m?1, and the pressure ratio over the interaction was 1.35. Particle image velocimetry is used as the main flow diagnostics tool, supported by oil-flow and Schlieren visualizations....journal article 2015

Xiong, Q. (author), Zhu, Q. (author), Zlatanova, S. (author), Du, Z. (author), Zhang, Y. (author), Zeng, L. (author)Indoor navigation is increasingly widespread in complex indoor environments, and indoor path planning is the most important part of indoor navigation. Path planning generally refers to finding the most suitable path connecting two locations, while avoiding collision with obstacles. However, it is a fundamental problem, especially for 3D complex...conference paper 2015

Two 25 L lab-scale UASB reactors were operated at an ambient temperature which varied between 17.1 and 28.6 °C. Ascaris suum egg was selected as the model egg considering its similarity...journal article 2015

We elaborate different parts of spatial model such as geometry, topology and semantics, and then present how they contribute to the processing of indoor tracks. The initial results of our experiment reveal...conference paper 2015

Yu, Z. (author)Fly ash is a by-product of burning coal in electric power generating plants. It is commonly known that owing to its pozzolanic properties fly ash is widely used as a partial replacement for Portland cement in concrete. The use of fly ash in concrete not only reduces the landfill costs of fly ash, but also reduces the use of Portland cement in...doctoral thesis 2015
