Evaluating the relation between spatial healthcare access and mortality during the COVID pandemic: Case Study from GOA State, India

In India the COVID-19 pandemic resulted in a nationwide lockdown from March 25, 2020 till the end of May 2020. During this time public and private transportation activities were limited, economic activities came to a standstill and healthcare resources were redistributed. India’s healthcare system faced problems prior to the COVID-19 pandemic...

Hex-Urban: Investigating the adoption of hexagonal grids to represent the total urban water cycle within a distributed water balance model

With urbanization and climate change, the reliable water supply by centralized system is facing challenges. Research on the (re)use of the outflow from an urban area as an alternative water resource is increasing in recent years. This research requires spatial and temporal information on the status of components of urban water cycle. Several...

Using Electric Vehicles to Store Solar Energy: The Spatial Distribution Problem: A quantitative analysis on the effects of the spatial distribution of solar panels and electric vehicles on the cost-effectiveness of the Vehicle-2-Home concept.

Vehicle-2-Home (V2H) is a concept in which an electric vehicle (EV) is able to charge and discharge its battery pack to the building it is connected to. This concept enables EVs to store surplus solar energy, which is produced during the daytime and return in to buildings during the night time. For this system to work (cost) efficiently, the EVs...

Internal wave generation in a non-hydrostatic wave model

In this work, internal wave generation techniques are developed in an open source non-hydrostatic wave model (SimulatingWAves till SHore, SWASH) for accurate generation of regular and irregular long-crested waves. Two different internal wave generation techniques are examined: a source term addition method where additional surface elevation is...

Importance of factors driving firms’ decisions on spatial distribution structures

The design of a spatial distribution structure is of strategic importance for companies, to meet required customer service levels and to keep logistics costs as low as possible. Spatial distribution structure decisions concern distribution channel layout–i.e. the spatial layout of the transport and storage system–as well as distribution...

A dispersive homogenization model for composites and its RVE existence

An asymptotic homogenization model considering wave dispersion in composites is investigated. In this approach, the effect of the microstructure through heterogeneity-induced wave dispersion is characterised by an acceleration gradient term scaled by a “dispersion tensor”. This dispersion tensor is computed within a statistically equivalent...

Hydrological and hydrodynamic processes and their impact on spatial characteristics of Terminos Lagoon, Mexico

Terminos Lagoon is the biggest and ecologically most important fluvial-lagoon system of the southern Gulf of Mexico. Rivers, sea and meteorology all influence the lagoon, variable over the year, resulting in a complex situation. To protect this area, it is crucial to know how different hydrological processes, hydrodynamic processes and spatial...

Operando Neutron Depth Profiling to Determine the Spatial Distribution of Li in Li-ion Batteries

Neutron Depth Profiling (NDP) allows determination of the spatial distribution of specific isotopes, via neutron capture reactions. In a capture reaction charged particles with fixed kinetic energy are formed, where their energy loss through the material of interest can be used to provide the depth of the original isotope. As lithium-6 has a...

Spatial distribution of surface velocities on the ebb tidal delta near Ameland

Drifters equipped with GPS-trackers have been widely used to investigate surface velocities in a wide range of coastal and oceanic settings. A detailed description of a new, cell-phone based, budget drifter system is given, along with an overview of the potential error sources and the magnitude of these sources. Drag related “windage” errors...

Global impacts of the meat trade on in-stream organic river pollution: The importance of spatially distributed hydrological conditions

In many regions of the world, intensive livestock farming has become a significant source of organic river pollution. As the international meat trade is growing rapidly, the environmental impacts of meat production within one country can occur either domestically or internationally. The goal of this paper is to quantify the impacts of the...

Runoff Modeling in Drainage Networks Using Probabilistic Graphs

Conventional hydrological models use a deterministic approach. One could think of it like a black box, having an input, parameters, relations and an output. The parameters are calibrated by comparing the model output with observations of the system response (for example river runoff). When assessing the uncertainty in models the focus is often...

Subspace identification of 1D spatially-varying systems using Sequentially Semi-Separable matrices

We consider the problem of identifying 1D spatially-varying systems that exhibit no temporal dynamics. The spatial dynamics are modeled via a mixed-causal, anti-causal state space model. The methodology is developed for identifying the input-output map of e.g a 1D flexible beam described by the Euler-Bernoulli beam equation and equipped with a...

Wave overtopping at rubble mound breakwaters with a non-reshaping berm

This thesis focuses on wave overtopping at rubble mound breakwaters with a non-reshaping berm. The research was aimed at gaining insight into the influence of a permeable berm on the overtopping behaviour. Moreover it was desired to validate existing prediction methods for the spatial distribution of overtopping for breakwaters with a non...

The influence of fissures on landslide hydrology

Preferential flow occurs in many soils and it is recognized to influence soil moisture distribution and hydrological fluxes at different scales. Preferential flow paths are formed for example by soil fauna, by plant roots or soil erosion. Water plays an important role in mass movement processes: rainwater or snow melt infiltrates into the soil...

Spatial distribution of overtopping

The scope of this research is to find an empirical formula to describe the distribution of wave overtopping in the region behind the crest. A physical model was set up in which irregular waves were generated. In order to find a formula which adequately describes the test observations, the influence of several parameters has been analysed. The...
