Securing Power Side Channels by Design

The security of electronic devices holds the greatest importance in the modern digital era, with one of the emerging challenges being the widespread occurrence of hardware attacks. The aforementioned attacks present a substantial risk to hardware devices, and it is of utmost importance to comprehend the potential detrimental effects they may...

Optimizing quantum error correction for superconducting qubit processors

The theory of quantum mechanics describes many phenomena that may initially seem to be counter-intuitive and, in some cases, impossible, given the understanding of classical mechanics that most of us are more intimately familiar with. Following its initial introduction, there was a great deal of debate among scientists regarding the predictions...

Influence and Detection of Vacuum Bag Leakages in Composites Manufacturing

Composites are increasingly used in the aerospace industry due to their lightweight potential and flexible design options. The most widespread manufacturing process for large components made of fibre composites is still the open mould process. In this process, a composite component is placed on a mould and hermetically sealed with a vacuum bag...

Mitigating Leakage and Noise in Superconducting Quantum Computing

Computers are used all over the place to perform tasks ranging from sending an email to running some complicated numerical simulation. That is brilliant of course, because computers enable us to solve a lot of problems in the world in this way. At the same time, for some of those problems, not even powerful supercomputers are enough to get the...

Water Loss Assessment in Distribution Networks: Methods, Applications and Implications in Intermittent Supply

Water utilities worldwide lose 128 billion cubic meters annually, causing annual monetary losses estimated at USD 40 billion. Most of these losses occur in developing countries (74%). This calls for a rethinking of the challenges facing water utilities in developing countries, foremost of which is the assessment of water losses in intermittent...

Modal methods for rehomogenization of nodal cross sections in nuclear reactor core analysis

This thesis develops novel first-principle methods to correct homogenization errors in nodal cross sections and discontinuity factors. Its aim is to improve the accuracy of nodal diffusion simulations of heterogeneous core configurations. This research builds upon previous work conducted at Framatome (Paris, France). It is based on a modal...

On self magnetic flux leakage in support of fatigue crack monitoring in ship and offshore structures: A numerical, experimental, and full-scale application study

Ship and offshore structures are prone to fatigue damage as they are cyclically<br/>loaded by waves. Therefore, regular inspection is needed in order to confirm adequate structural integrity throughout the entire service life of the structure. Detected fatigue cracks that are too long for safe operation need to be repaired. Detected cracks of...
