This work proposes a new charge pump design suitable for energy harvesting on small human wearable devices. By using only one system for both cold start and high efficiency harvesting, the required silicon area is heavily reduced. The most fitting energy transducer is determined to be a photovoltaic cell, based on aspects of voltage, power and...

The German Aerospace Centre (DLR) has in the past years been performing test runs with their experimental sub-scale combustion chambers to measure and investigate the effects of unstable combustion. Some of these investigations are focused on the heat flux to the chamber walls, changes in which can cause a significant shift in chamber wall...

A young boy with type 1 Diabetes Mellitus is supported by a social robot on the road to self-management. The robot has knowledge on the goals that the boy needs to reach, as discussed with his health care professional. The robot also knows the boy’s activity options and preferences. It suggests activities based on this knowledge, but also...

In this PhD thesis, we investigate the microstructural evolution and damage in different steel grades used in railway applications such as switches, crossings and curved tracks, which are the key components in the rail transportation industries around the world. The damage in these components leads to a maintenance cost of billions of Euros per...

Bouwteam is a collaboration agreement in which the contracor is involved early on to work together with the client to make a design in which the knowledge of the client and the contractor is used optimally. Through the years the Bouwteam has been influenced by integrated contracts and has been changing in a variety of ways. Nowadays, there is...

Stochastic systems have been widely investigated and employed in numerous
applications in different areas such as finance, biology and engineering as
they allow accounting for imprecisions so often faced in every practical tasks. Often that task would require to find the best action sequence in order to optimize the outcome. When the...

Balz, V.E. (author)
This thesis elaborates on the role and position of regional design in spatial planning. Building upon the argument that design in this realm aims to improve planning guidance by judging its implications for particular situations, the thesis develops an analytical framework for an enhanced understanding of how design both influences, and is...

Korte, Ruben (author)
Once a semi-submersible is operating at an inconvenient draft (A shallow draft with limited water column above the pontoons), the passing waves over the pontoons can not keep their linear motion and energy will be transferred to higher harmonic wave frequencies. This means the hydrodynamic response will also contain energy at these higher...

Organ-on-chip (OoC) devices are increasingly used for biomedical research and to speed up the process of bringing a medicinal drug from the lab to the market. The technology also addresses ethical issues linked to animal testing as it offers a reduction in animal experiments through its possibility to mimic the environment in the human body....

Simulation models are increasingly used to substantiate long-term planning policy decisions. The communication of model results from modellers to policy-makers has not received much attention by scholars. While, without correct interpretation and correct use of model results the quality of the model itself is irrelevant for the impact of the...

High power electronics with wide band gap semiconductors are becoming the most promising devices in new energy power suppliers and converters. Highly reliable die attach materials, serving as one of interconnections, play critical roles in power electronic packages and modules. Among which, the nanosilver paste/film has become a promising die...

In this thesis, the usage of scenarios for the participatory application of ADM is investigated in the context of the Paraná Delta, in Argentina. The focus is two-fold: (1) the research focuses on how a participatory design for ADM can be made, and (2) it focuses on which moment of the framework scenarios should be introduced in the...

Current photovoltaic (PV) industrial chain mainly serves the conventional utility-scale PV power stations. Rigid and opaque silicon-based PV modules domain the market so far. As distributed PV capacities expand, PV modules tend to be integrated with existing infrastructures (mostly, buildings). To adapt with the building environment, innovative...

The aim of this thesis is to study the nature of photoexcitations and carrier multiplication in low-dimensional semiconductors using ultrafast spectroscopy techniques. Ongoing from a macroscopic scale to a nanoscale, the electronic and
optical properties of a material become size dependent, and differ significantly from their bulk...

This thesis focuses on improving the phase noise and power efficiency
of millimeter-wave (mm-wave) frequency synthesizers in nanometer CMOS.
The mm-wave frequency spectrum is widely adopted in various upcoming
volume commercial wireless applications. These new applications provide
more interconnection between the physical and...

Global warming, continuous demand on energy from fossil fuels as a limited natural resource, and costumers’ high expectations regarding product quality are three global challenges that the automotive industry is facing. Fuel consumption reduction has a significant impact on preserving fossil fuels, lowering fossil fuel dependency and the CO2...

Modern surveillance radars are designed to detect moving targets of interest in an adverse environment, which can encompass strong unwanted reflections from ground or sea surface, clouds, precipitation, etc. Detection of weak and small moving targets in environmental clutter remains, however, a challenging task for the existing radar systems....

River discharge is an essential parameter in morphodynamic modelling. It proves to be highly variable in both time and space. In this thesis the impact of the schematisation of time-dependent discharge series on morphodynamic change is studied. The impact is governed by several factors such as the long-term discharge statistics, and both short-...

Lately structural safety is an often discussed subject in The Netherlands. Recent collapses have made people question if our buildings are actually safe enough. Research shows that the individual probability of death due to structural failure is below the limit of 10-5 per year. However, it is unknown if every single building is safe enough as...
