de Bruijckere, J. (author)In this thesis we study charge transport through individual molecules and mainly focus on the properties of molecular spin. We fabricate nanoscale structures for transport measurements and employ the electromigration break-junction technique to realize three-terminal—transistor-like—single-molecule devices. We investigate the spin-related...doctoral thesis 2020

Kumar, Karishma (author)Detailed imaging of blood flow may improve the understanding of brain functions. The state-of-the-art non-invasive flow imaging of the brain is limited to a one-dimensional Doppler setting. We propose a method to estimate the two-dimensional flow vector in the fine vascular network of the brain by using a speckle tracking technique. The...master thesis 2020

Karaiskou, Antigoni (author), Turrin, M. (author), Tenpierik, M.J. (author)Speech intelligibility is crucial in many spaces, yet designers often fail to predict the acoustic shortcomings of certain design choices. This paper builds on the potential of hybrid surface treatments showcasing low-frequency absorption to control background noise levels and high-frequency diffusion to improve speech-in-noise perception to...conference paper 2020

Cheng, L. (author), Xin, H. (author), Groves, R.M. (author), Veljkovic, M. (author)S460 steel is increasingly used in civil engineering, especially in a harsh environment such as offshore structures [1]. Material damage is inevitable for structures subjected to static and dynamic loads during their technical life time. Thus, monitoring material damage is important for providing information regarding critical damage of in...abstract 2020

Kilic, H. (author), Gumus, Bilal (author), Khaki, Behnam (author), Yilmaz, Musa (author), Palensky, P. (author)n this paper, a robust data-driven method for fault detectionin photovoltaic (PV) arrays is proposed. Our method is based onthe random vector functional-link networks (RVFLN) which has theadvantage of randomly assigning hidden layer parameters with no tuning. To eliminate the effect of measurement noise and overfitting in thetraining process...other 2020

(author)Aggradation and fluvial incision controlled by downstream base-level changes at timescales of 10 to 500 kyr is incorporated in classic sequence stratigraphic models. However, upstream climate control on sediment supply and discharge variability causes fluvial incision and aggradation as well. Orbital forcing often regulates climate change at...journal article 2020

Tronchin, Lamberto (author), Merli, Francesca (author), Manfren, Massimiliano (author), Nastasi, B. (author)During the renovation of auditoria and concert halls, the acoustic quality is normally evaluated from measurements of impulse responses. One possibility for evaluating the acoustic quality from the measurements (the simulations) consists of convolving anechoic music with the measured (or simulated) impulse responses.
