This study proposes a framework to analyze accelerated degradation testing (ADT) data in the presence of inspection effects. Motivated by a real dataset from the electric industry, we study two types of effects induced by inspections. After each inspection, the system degradation level instantaneously reduces by a random value. Meanwhile, the...

MAX phases are a family of ternary carbide or nitride ceramics possessing a layered crystal structure and, due to their chemical bonds having a mixed covalent-ionic-metallic nature, have unique properties combining those of metals and ceramics. In this review, the formation mechanisms of MAX phases from elemental and compound powders are...

Under the high requirement of ballast materials and the frequent maintenance of high-speed and heavy-haul railway, the maintenance cost and material consumption become an important problem. Several methods are used to increase the stability and service life of railway structure, also using recycled materials in ballast bed construction can be a...

The abundance of methane has led to a strong interest to use methane as a feedstock in the chemical industry. One of the main challenges is the initial activation of the methane molecule. In this thesis, heterogeneous catalysts for two different methane conversion processes are investigated. Firstly, the deactivation of supported Ni catalysts...

This thesis presents novel ways of recovering of valuable compounds from food industry side streams. It does so via evaluating two case studies for the valorization of such streams. These types of streams are often referred to as waste and discarded. However, they are rich sources of nutraceuticals (e.g polyphenols), proteins and dietary fiber....

Bhangale, J.A. (author)
The work done for this thesis is related to fatigue analysis of various material types used in the wind turbine blades. For the analysis, a framework from the thermodynamics of irreversible processes with internal variables and Continuum Damage Mechanics (CDM) is used. Thermodynamic principles provide a generic framework that is valid for the...

Given the considerable range of applications within the European Union Copernicus system, sustained satellite altimetry missions are required to address operational, science and societal needs. This article describes the Copernicus Sentinel-6 mission that is designed to provide precision sea level, sea surface height, significant wave height,...

Seal area represents the most problematic part in food packaging for controlling the moisture and gas ingress and preserving product quality. Understanding the mechanism of heat sealing, which is a widely used method in flexible packaging, is critical for maintaining product quality throughout the storage and preventing food waste. Likewise,...

A substantial part of urban surfaces is to some extent impermeable. Rainfall on these areas turns into runoff, which mobilises solids present on these surfaces. This runoff is removed from urban built areas by different type of drainage systems via gully pots. The objective of a gully pot is twofold, namely 1) to convey runoff to the drainage...

The urgent need to transition to a climate-neutral society requires rapid development and adoption of renewable technologies. Key enablers of conventional and future renewable energy conversion technologies are turbomachines. However, the specific requirements of these turbines and compressors, e.g. operation under highly non-uniform flow or...

This dissertation aims to understand the behavior of pedestrians and cyclists when interacting with automated vehicles (AVs). The role of AVs’ characteristics such as their physical appearance, whether a driver is present, the presence of external communication interfaces, and factors pertaining to the behavior of the vehicle were investigated...

Polymer flooding is a commercially viable chemical enhanced oil recovery (cEOR) method. It includes the injection of water-soluble polymers into a reservoir to improve the drive water viscosity and consequently to increase the sweep and displacement efficiency of the water. Despite the success in both laboratory and field applications, there are...

Our routines play an important role in a wide range of social challenges such as climate change, disease outbreaks and coordinating the staff and patients of a hospital. Studying these systems via agent-based simulations (ABS) enables researchers to gain insight into complex aspects of these challenges such as human interaction, learning,...

This thesis explores the coupling of microwave cavities containing a Superconducting QUantum Interference Device (SQUID) to a mechanical resonator by means of a flux-mediated optomechanical coupling scheme, and to a Radio-Frequency (RF) circuit via a photon-pressure interaction. While flux-mediated optomechanical systems open the door for the...

Increasing demand for energy from renewable sources has resulted in ambitious plans to construct a large number of offshore wind farms in the coming years. In relatively shallow water depths, the preferred support structure for wind turbines is the steel monopile, which is a thin-walled cylindrical structure. To decrease the cost of the...

The rapidly expanding field of tissue engineering presents enticing, yet demanding challenges for scientists and engineers across many different disciplines. The ultimate goal of tissue engineering is ambitious: to regenerate damaged or missing tissue in its full complexity, either in vitro or in situ, and restore organ function. In addition to...

The circular economy offers an alternative to the linear economy (also called the take-make-use-waste society) we live in. It puts emphasis on using resources effectively by slowing and closing resources loops. Design is seen as enabler in a circular economy. Design decisions taken now have an impact on the recovery of products in the future....
