The impact of regular school closure on seasonal influenza epidemics: a data-driven spatial transmission model for Belgium Hasselt University University of Antwerp
Background: School closure is often considered as an option to mitigate influenza epidemics because of its potential to reduce transmission in children and then in the community. The policy is still however highly debated because of controversial evidence. Moreover, the specific mechanisms leading to mitigation are not clearly identified. Methods: We introduced a stochastic spatial age-specific metapopulation model to assess the role of ...

Performance of F-DMAS beamforming with adjustable maximum spatial lag in multi-line transmission ultrasound imaging KU Leuven
© 2018 IEEE. In Multi-Line Transmission (MLT) ultrasound imaging, high frame-rate is achieved by the simultaneous transmission of multiple focused beams along different directions. Image contrast is potentially degraded by cross-talk artifacts that, however, can be successfully attenuated e.g. by Filtered-Delay Multiply and Sum (F-DMAS) beamforming. F-DMAS is based on the computation of the autocorrelation of the aperture in reception, which is ...
Optimization of Transmission Technology and Routes for Pan – European Electricity Highways Considering Spatial Aspects KU Leuven
© 2015 IEEE. An algorithm to determine optimal transmission routes and to perform technology selection for transmission system expansion is developed and presented in this paper. The aim of the optimization is to minimize investment and installation costs of grid expansion, taking into account spatial properties. The optimization is performed by formulating possible expansion options around a weighted graph and using a modified A∗ shortest path ...
A spatial windowing technique to account for finite dimensions in 2.5D elastodynamic transmission and radiation problems KU Leuven
The dynamic interaction between a layered halfspace and quasi translationally invariant structures such as roads, railway tracks, tunnels, dams, and lifelines can be modelled using a computationally efficient 2.5D approach, assuming invariance of the geometry in the longitudinal direction. This assumption is not always fulfilled in practice, however. Even for elongated structures, full 3D computations may still be required for an accurate ...
High spectral and spatial resolution X-ray transmission radiography and tomography Ghent University
In high-resolution radiography and tomography, the local intensity of the X-ray beam is typically measured using an energy-integrating detector system, thus discarding all information on the detected X-ray spectrum. Recently, several direct or hybrid detector systems have been developed which allow for single photon counting using one or more energy thresholds [1]. By measuring the same object at different energy thresholds, it becomes possible ...
