Teunissen, P.J.G. (author)The minimum mean squared error (MMSE) criterion is a popular criterion for devising best predictors. In case of linear predictors, it has the advantage that no further distributional assumptions need to be made, other then about the first- and second-order moments. In the spatial and Earth sciences, it is the best linear unbiased predictor (BLUP...journal article 2007

Vázquez Anzola, Diego Alejandro (author)The aim of this project is to compute, as accurately as possible, the electric field – with the diffusive approximation (ωε→ 0) – in the upper half space (e.g., air), in the lower half space (i.e., ground or sediments), and at the surface, for an x-directed electric dipole point source J ̂_1^e located just above – or just below – the interface...master thesis 2007

Pel, A.J. (author)Binnen dit thesis rapport bespreken we een generieke methode voor het evalueren van verschillende typen evacuatie schema’s. Daartoe wordt eerst de theorie over evacuatie (gedrag) samengevat. Bij de theorievorming bespreken we de voornaamste aspecten welk invloed uitoefenen op het keuzegedrag van de evacués. Het betreft dan de keuzen om deel te...master thesis 2007

Yan, F. (author), Migliorato, P. (author), Ishihara, R. (author)The influence of twin boundaries on the characteristics of single grain-silicon thin film transistors has been analyzed by three-dimensional simulation. The simulations show that the orientation and the location of a twin boundary could affect the field-effect mobility and the leakage current of a device. The field-effect mobility increases with...journal article 2007

Lua, E.K. (author), Zhou, X. (author)Peer-to-Peer (P2P) overlay networks can be utilized to deploy massive Internet overlay services such as multicast, content distribution, file sharing, etc. efficiently without any underlying network support. The crucial step to meet this objective is to design network-aware overlay network topologies connecting all nodes that offer promising...conference paper 2007

Roeselers, G. (author), Van Loosdrecht, M.C.M. (author), Muyzer, G. (author)Phototrophic biofilms occur on surfaces exposed to light in a range of terrestrial and aquatic environments. Oxygenic phototrophs like diatoms, green algae, and cyanobacteria are the major primary producers that generate energy and reduce carbon dioxide, providing the system with organic substrates and oxygen. Photosynthesis fuels processes and...journal article 2007

Vos, R. (author)This thesis presents the use of a new class of flight control actuators employing Post-Buckled Precompressed (PBP) piezoelectric elements in morphing wing Uninhabited Aerial Vehicles (UAVs). The new actuator relies on axial compression to amplify deflections and control forces simultaneously. Two designs employing morphing wing panels based on...master thesis 2007

(author)Natural phototrophic biofilms are influenced by a broad array of abiotic and biotic factors and vary over temporal and spatial scales. Different developmental stages can be distinguished and growth rates will vary due to the thickening of the biofilm, which is expected to lead to a limitation of light or mass transport. This study shows that...journal article 2007

Khalili Amiri, P.K. (author), Rejaei, B. (author), Vroubel, M. (author), Zhuang, Y. (author)The authors report on the observation of nonreciprocal spin wave propagation in a thin ( ? 200?nm) patterned Ni–Fe stripe. The spin wave transmission spectrum is measured using a pair of microstrip lines as antennas. The nonreciprocity of surface wave dispersion brought about by an adjacent aluminum ground leads to a nonreciprocal coupling of...journal article 2007
