Kumar, N. (author), Abdi, F.F. (author), Trzesniewski, B. (author), Smith, W.A. (author), Planken, P.C.M. (author), Adam, A.J.L. (author)We demonstrate emission of terahertz pulses from a BiVO4/Au thin film interface, illuminated with femtosecond laser pulses. Based on the experimental observations, we propose that the most likely cause of the THz emission is the Photo-Dember effect caused by the standing wave intensity distribution formed at the BiVO4/Au interfaces.journal article 2015

We perform renormalization group analysis (RG) of the Navier-Stokes equation in the presence of constant mean velocity field $\mathbf U_0$, and show that the renormalized viscosity is unaffected by $\mathbf U_0$, thus negating the ``sweeping effect", proposed by Kraichnan [Phys. Fluids {\bf 7}, 1723 (1964)] using random Galilean invariance....conference paper 2015

Kumar, S.S. (author)The sustained increase in computational performance demanded by next-generation applications drives the increasing core counts of modern multiprocessor systems. However, in the dark silicon era, the performance levels and integration density of such systems is limited by thermal constraints of their physical package. These constraints are more...doctoral thesis 2015

Kumar, M. (author), Schuttelaars, H.M. (author), Roos, P.C. (author), Möller, M. (author)In this paper, a three-dimensional semi-idealized model for tidal motion in a tidal estuary of arbitrary shape and bathymetry is presented. This model aims at bridging the gap between idealized and complex models. The vertical profiles of the velocities are obtained analytically in terms of the first-order and the second-order partial...journal article 2015

Kumar, A. (author)A seismic survey should be designed such that imaging of the acquired data leads to a sufficiently accurate subsurface image. For that purpose, methods for acquisition geometry analysis and design are available. These methods are used to judge whether an acquisition geometry is suited for the specified objectives. Conventional 2D and 3D...doctoral thesis 2015

Kumar, Kavisha (author), Ledoux, H. (author), Stoter, J.E. (author)In addition to buildings, the terrain forms an important part of a 3D city model. Although in GIS terrains are usually represented with 2D grids, TINs are also increasingly being used in practice. One example is 3DTOP10NL, the 3D city model covering the whole of the Netherlands, which stores the relief with a constrained TIN containing more than...conference paper 2016

Kumar, Kavisha (author), Ledoux, H. (author), Stoter, J.E. (author)Point cloud data are an important source for 3D geoinformation. Modern day 3D data acquisition and processing techniques such as airborne laser scanning and multi-beam echosounding generate billions of 3D points for simply an area of few square kilometers. With the size of the point clouds exceeding the billion mark for even a small area,...conference paper 2016

Wei, X. (author), Kumar, M. (author), Schuttelaars, H.M. (author)Along-channel and cross-channel sediment transport in tidal estuaries is usually driven by tides, density gradients, Coriolis’s force, wind stress, channel curvature and bathymetric variations. Since the water motion is influenced by density-induced gravitational circulation which in turn affects the salinity distribution, the coupled water...abstract 2016

Chen, Wen L. (author), Roos, Pieter C. (author), Schuttelaars, H.M. (author), Kumar, M. (author), Zitman, T.J. (author), Hulscher, SJMH (author)Because wind is one of the main forcings in storm surge, we present an idealised process-based model to study the influence of topographic variations on the frequency response of large-scale coastal basins subject to time-periodic wind forcing. Coastal basins are represented by a semi-enclosed rectangular inner region forced by wind. It is...journal article 2016

Koc, Y. (author), Raman, Abhishek (author), Warnier, Martijn (author), Kumar, Tarun (author)Power grid outages cause huge economical and societal costs. Disruptions in the power distribution grid are responsible for a significant fraction of electric power unavailability to customers. The impact of extreme weather conditions, continuously increasing demand, and the over-ageing of assets in the grid, deteriorates the safety of...journal article 2016
