For the degree of Doctor of Engineering Sciences and Technology The minimization of nitrogen oxides (NOx) emissions is among the major concerns of combustion-related processes, together with the adverse effects related to the emission of greenhouse gases.

Double, double toil and trouble; Fire burn, and cauldron bubble: The influence of hydrothermal alteration on the stability of a volcano Hydrothermal alteration is near-ubiquitous at volcanoes worldwide and is thought to promote volcano instability and flank collapse.

In this presentation, we develop an innovative approach - X-MESH - to overcome a major difficulty associated with numerical simulation in engineering: we aim to provide a revolutionary way to track physical interfaces in finite element simulations. The idea is to use so-called extreme mesh deformations.

The presentation will start with some background into the basic principles of nonlinear flight dynamics, followed by a description of airliner upset and loss-of-control problems: their relevance, how they are manifested and potential causes. Then continuation methods and bifurcation analysis will be introduced as a means of studying nonlinear dynamical systems.

For the degree of Doctor of Engineering Sciences and Technology Birds have inspired human innovation and technology for centuries. The first documented human flying attempt dates back the late 800, from Abbas ibn Firnas who created what is considered the first aviation experiment.

For the degree of Doctor of Engineering Sciences and Technology The exponential growth of technology opened the door for a new generation of locomotion assistive devices (e.g. prostheses and exoskeletons) to emerge. However, such systems still face several challenges regarding their interactions with human users.

In dynamic, mechatronic and robotic systems, a basic mechanical component for transmitting motion, force, and power between motor and load is a chain of gears. This type of transmission system is specifically effective for lightweight, small, but large output torque, for example, flapping wing micro aerial vehicles (FWMAV’s).

For the degree of Doctor of Engineering Sciences and Technology Every year, migratory birds liven the sky up by aligning in arrows and drawing impressive V-shapes. The energetic efficiency of this flying technique is explained by the existence of a wake in a region behind every individual and that each can perceive.

For the degree of Doctor of Engineering Sciences and Technology The autothermal chemical looping reforming (aCLR) is an alternative technology to steam methane reforming (SMR) and partial oxidation of methane (POM) aiming at solving CO2 capture and improving their energy efficiency.

For the degree of Doctor of Engineering Sciences and Technology Burning fossil fuels for energy production has caused a significant increase in CO2 emissions. Excessive emission over the past decades is leading to catastrophic problems for the environment related to global warming.
