Items that a user can see when he uses the general result page of a modern search engine can be categorized as verticals. Some examples of verticals are images, videos, news, shopping. Heterogeneous search engine result pages encompass result pages that contain results from different verticals. It is widely used and has been proven to improve...

This research focuses on the analyze of the heterogeneity of the Groningen gas field, i.e. characterization of the reservoir rock and the sealing Zechstein salt on top of the reservoir, by modeling the rock properties of the formations. The aim of this study is twofold, namely to characterize the thickness, shale content and porosity of the...

A homogeneous dynamic reservoir model has been build for the Delft Sandstone Member, but geological formations are never completely homogeneous. The objective of this study is to increase knowledge about the heterogeneity of the Delft Sandstone Member for the construction of a future heterogeneous dynamic reservoir model of the Delft Sandstone...

DWARV is a C-to-VHDL compiler which can compile arbitrary C programs for a heterogeneous platform with minimal effort. Depending on the application this will imply faster execution. We give an overview of C-to-VHDL compilers. One important aspect of all software is its reliability, and we aim to assess DWARV’s reliability and the adequacy of its...

The Delft Geothermal Project is an ongoing study in search for the best way to produce renewable energy from the Delft Sandstone Member. So far, a homogeneous reservoir model, a study of the regional geology and a study of the fluid flow and heat transfer have been made. For these studies, information is used from the Moerkapelle oil field...

In this chapter, we present a methodological approach for Smart Mobility that integrates three key features: prediction, optimization, and personalization. They are integrated in such a way that when a travel menu is offered, predicted conditions are considered in the attributes of alternatives and optimized system-level policies are maintained....

The effect of probability distributions on the slope reliability is highlighted in this study since the lognormal distribution is often used to characterize the variability of soil properties to avoid negative values. A multiple response-surface based MCS method for slope reliability analysis in spatially variable soils is proposed. A...

We examine the influence of heterogeneous curing rates for a SIS model, used for malware spreading on the Internet, information dissemination in unreliable networks, and propagation of failures in networks. The topology structures considered are the regular graph which represents the homogenous network structures and the complete bi-partite...

Concurrent multiscale analysis of quasi-brittle heterogeneous materials such as concrete and rock is conducted employing non-overlapping domain decomposition techniques. Initially a coarse discretization with effective properties is considered at each domain. A zoom-in technique is performed at those domains in which non-linearities take place....

We study two-level overlapping domain decomposition preconditioners with coarse spaces obtained by smoothed aggregation in iterative solvers for finite element discretisations of second-order elliptic problems. We are particularly interested in the situation where the diffusion coefficient (or the permeability) is highly variable throughout the...

Subsurface hydraulic properties are mainly governed by the heterogeneity of the porous medium considered. Our work aims at characterizing the asymptotic dispersion coefficients for highly heterogeneous permeability fields triggered by advection and constant local dispersion-diffusion. We have developed a fully parallel software for simulating...

ASR (alkali-silica reaction) is one of the toughest durability problems in engineering. However, the damage induced by ASR is still fairly unpredictable due to the lack of microstructural information of cement-based materials affected by ASR, while the microstructure determines the global performance. In order to fill this gap, a multiscale...

Several models are discussed for seismic wave propagation in periodically layered poroelastic media where layers represent mesoscopic-scale heterogeneities that are larger than the pore and grain sizes but smaller than the wavelength. The layers behave according to Biot’s theory. Wave propagation normal to the layering is considered and the...

The subsurface plays an important role when assessing flood risk and its build up has to be known in considerable detail to properly determine the chance of flood-protection failure. Currently, the subsurface below flood-protections is often characterized by geotechnical cross sections that are constructed using e.g. cone penetration tests (CPTs...
