Energy shortage and energy related environmental problems are urgent issues to be addressed in the coming years. Low-grade heat is utilized to drive energy conversion cycle and to produce electricity, which is a renewable and sustainable approach to energy supply. These thermodynamic cycles for energy conversion require eco-friendly working...

For the past century, fluidized beds have been standard equipment in many branches of industry. In most applications they are used to manipulate granular and powder-like materials, whose particles can roughly be approximated as spheres. Therefore, numerical models and investigations have focused mainly on fluidized beds with spherical particles....

Vrolijk, J. (author)
In exploration geophysics, seismic measurements are used to obtain information about the subsurface. A large proportion of these measurements take place in oceans, seas and lakes, where the sources and the receivers are generally located somewhere between the water bottom and the water surface during data acquisition. The sources emit an...

This thesis explores the potential of self-regulation in collective decision making to align interests and optimise joint performance. Demonstrated in the domain of road maintenance planning, this research contributes novel incentive mechanisms and algorithmic techniques to incite self-regulation and coordinate agent interactions, paired with a...

Boersma, Q.D. (author)
Responsibly using the subsurface for geo-energy extraction or storage requires an accurate understanding of the static and dynamic behaviour of the targeted reservoirs. While mostly dependent on intrinsic rock properties (e.g. porosity and permeability), this behaviour is also believed to be significantly impacted by the presence of natural...

Stokkermans, T.C.A. (author)
This research is on the aerodynamics of propellers in interaction. As a propeller is dependent on the flowfield it encounters, any disturbance in that inflow results in changes in loading on the propeller. This can result in propulsive efficiency changes and affect stability through generation of in-plane forces and out-of-plane moments. The...

Guo, W. (author)
With the increasing volumes of containers in global trade, efficient global container transport planning becomes more and more important. To improve the competitiveness in global supply chains, stakeholders turn to collaborate with each other at vertical as well as horizontal level, namely synchromodal transportation. Synchromodality is the...

Kupski, J.A. (author)
Adhesive bonding is one of the most suitable joining technologies in terms of weight and mechanical performance for current carbon fiber reinforced polymer aircraft fuselage structures. However, traditional joint topologies such as single overlap joints induce high peel stresses, resulting in sudden failure and low joint strength when compared...

Visser, J.L. (author)
Integrated design is a frequently used term in academics and practice. However, a common ground in the application of terminology, methodology, and description of insights from practice with respect to integrated design is lacking. Therefore, this dissertation describes a framework for integrated design that can be used as a platform for...

March, G. (author)
The German CHAMP, US/German GRACE, and European Space Agency (ESA) GOCE and Swarm Earth Explorer satellites have provided a data set of accelerometer observations allowing the derivation of thermospheric density and wind products for a period spanning more than 15 years. With the advent of highly accurate satellite accelerometer measurements,...

Mohammadloo, Tannaz H. (author)
Detailed information about the sea and river bed is of high importance for a large number of applications, such as marine geology, coastal engineering, safe navigation and offshore construction. Acoustic remote sensing techniques have become extremely attractive for obtaining bathymetry measurements and for mapping the sediment properties, due...

Abdelrady, Ahmed (author)
In many developing countries, water demand is increasing while surface- and groundwater resources are threatened by pollution and overexploitation. Hence, a more sustainable approach to water resources management and water treatment is required. In this capacity, bank filtration is a natural treatment process that makes use of the storage and...

Smits, M.W.M. (author)
This research project focuses on how decisions made by practitioners, articulating rural housing in Sub-Sahara Africa, contribute to the decreasing level of self-reliance inhabitants have regarding their housing. Multiple case studies on Mt. Elgon proved that inhabitants have a significantly higher self-reliance level, comparing traditional to...

Hassaballah, K.E.A. (author)
The spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the...

Vasilakou, E. (author)
Dynamic environmental conditions govern microbial metabolism and affect cellular growth. Many applications in biotechnology require cultivating microorganisms in large-scale bioreactors. These environments are commonly characterized by physicochemical gradients, due to imperfect mixing and have been the cause of reduced...

Hoseini, E. (author)
The Netherlands has a long history of protecting against flooding and high water levels. Due to the climate change and the sea level rise, the next flood could have a high impact on this small country. Hoogwaterbeschermingsprogramma (HWBP), the current largest flood defence program in the Netherlands, makes sure that all the flood defence...

Ahmed, M.B.M. (author)
Climate change (CC), as predicted by several global climate models, is very likely to have severe impacts in the future, on top of all other global changes. These impacts may have significant influence on natural resources especially surface and groundwater. This influence is particularly problematic for the Mediterranean coastal areas, and...

Peltenburg, J.W. (author)
Because of fundamental limitations of CMOS technology, computing researchers and the computing industry are focusing on using transistors in integrated circuits more efficiently towards obtaining a computational goal. At the architectural level, this has led to an era of heterogeneous computing, where various types of computational components...

Rahrah, M. (author)
As demand for water increases across the globe, the availability of fresh water in many regions is likely to decrease due to a changing climate, an increase in human population and changes in land use and energy generation. On the other hand, climate scenarios predict extreme periods of drought and rainfall. Heavy rainfall regularly leads to...

Skin is one of the most significant parts of the human body. It connects us with the environment and has a vast number of functions, among which defensive function is of a high importance. Skin structure and its layers may vary with a number of factors such as sight, age, sex, race and the overall health state of the individuals. The latter...
