Jalali Sohi, A. (author), Hertogh, M.J.C.M. (author), Bosch-Rekveldt, M.G.C. (author), Blom, R. (author)Still, projects in the construction sector are delivered with time delays and cost overruns. One of the reasons for poor performance was assigned to project complexity. A combination of lean construction and agile project management are hypothesized as a possible solution to cope with project complexity. In this paper we aim to understand if the...conference paper 2016

Zhou, Y. (author), van Kampen, E. (author), Chu, Q. P. (author)Flapping-wing MAVs represent an attractive alternative to conventional designs with rotary wings, since they promise a much higher efficiency in forward flight. However, further insight into the flapping-wing aerodynamics is still needed to get closer to the flight performance observed in natural fliers. Here we present the first step necessary...conference paper 2016

Ho, H.W. (author), de Croon, G.C.H.E. (author), Chu, Q. P. (author)Monocular vision is increasingly used in Micro Air Vehicles for navigation. In particular, optical flow, inspired by flying insects, is used to perceive vehicles’ movement with respect to the surroundings or sense changes in the environment. However, optical flow does not directly provide us the distance to an object or velocity, but the ratio...conference paper 2016

Petrov, N. (author), le Chevalier, F. (author), Yarovoy, Alexander (author)In this paper the influence of clutter power spectrum on unambiguous radar target detection with single low pulse repetition frequency wideband waveform is analyzed. Impact of both stationary and diffuse clutter components for different signal bandwidths and coherent processing intervals (CPI) is studied. Exponential model of the ground clutter...conference paper 2016

Carvalho, João (author), Ghose, R. (author), Alves, D. (author), Leote, J (author)Expressions of ductile, soft-sediment deformations induced by ground movements due to past earthquakes are difficult to recognize in near-surface soils. We have carried out shallow S-wave reflection studies in a seismically active area located northeast of metropolitan Lisbon, Portugal. Identifying shallow disturbed zones and hidden fault...journal article 2016

Schiemann, M. (author), de Haan, A.B. (author), Wirtz, S. (author)Spray roasting of metal chloride solutions is frequently used in steel industries to recover pickling liquids. As spray roasting reactors are difficult to characterize experimentally, computational fluid dynamics simu- lations have been used to investigate reactor performance. These simulations require a particle formation model, which describes...journal article 2016

Minato, S. (author), Ghose, R. (author)Though well known for layer boundaries, the use of amplitude-versus-offset (AVO) variations for non-welded boundaries like fractures is not yet investigated. Depending on the seismic wavelength used, fractures can be regarded as thin, compliant zones in rocks, in different scales. We explore the potential of multiangle AVO inversion of P-P and P...journal article 2016

Kleinepier, T. (author), van de Valk, H.A.G. (author)Background: Despite extensive research on the family behavior of young adults, family dynamics of children of migrants remain largely unexplored. This is unfortunate as family transitions are strongly interlinked with transitions in other domains (e.g., education, work) and predictive for outcomes later in life.<br/><br/>Objective: We provide a...journal article 2016

van Riel, W. (author), Post, J.A.B. (author), Langeveld, J.G. (author), Herder, P.M. (author), Clemens, F.H.L.R. (author)Operational decision-making processes for networked infrastructure management often occur as a multi-actor planning problem, implying these are based on negotiations between different stakeholders in addition to available system quality information. As such, does more accurate data about actual structural condition lead to other or better...journal article 2016

Shamasundara, R. (author), Mulder, W.A. (author)Finite-element discretizations of the acoustic wave equation in the time domain often employ mass lumping to avoid the cost of inverting a large sparse mass matrix. For the second-order formulation of the wave equation, mass lumping on Legendre–Gauss–Lobatto points does not harm the accuracy. Here, we consider a first-order formulation of the...journal article 2016

Read, S.A. (author), Lindhult, Erik (author), Mashayekhi, A. (author)Our present economy is high-energy and demand-intensive, demand met through the use of high energy yield fossil fuels. Energy efficiency and renewable energy sources are proposed as the solution and named the ‘twin pillars’ of sustainable energy policy. Increasing energy efficiencies are expected to reduce energy demand and fossil fuel use and...journal article 2016

Policy learning from different parts of the world significantly shaped the formation and expansion of the MLSS, and Chinese social policy researchers have drawn...journal article 2016

Tangdamrongsub, N. (author), Hwang, Cheinway (author)We present a theory and numerical algorithm to directly determine the time-varying along-track geopotential difference and deflection of the vertical at the Gravity Recovery and Climate Experiment (GRACE) satellite altitude. The determination was implemented using the GEOGRACE computer program using the K-band range rate (KBRR) of GRACE from...journal article 2016

Kadu, Ajinkya (author), van Leeuwen, Tristan (author), Mulder, W.A. (author)<br/>In seismic exploration, the delineation of large bodies with hard exterior contrasts but nearly constant interior properties is a challenge. Examples include salt diapirs, salt slabs, anhydrite or basalt layers. Salt geometries are of particular interest because they often have hydrocarbon reservoirs on their sides or underneath. This...conference paper 2016
