Bayraktaroglu, H. (author), Hicks, M.A. (author), Korff, M. (author)In this paper, a state-dependent semi-micromechanical framework for anisotropic sands is proposed. A simple constitutive model based on critical state theory and bounding surface (BS) plasticity is used to describe idealized micro-level soil behaviour, and a slip theory based multilaminate framework employed to create a link between the micro...conference paper 2023

Mortimer, William (author), Calvert, R. (author), Antonini, A. (author), Greaves, Deborah (author), Raby, Alison (author), van den Bremer, T.S. (author)Experiments are contaminated by second-order error waves at sub- and super-harmonic frequencies when first-order wave generation is used. Herein, we investigate by experiment the implications of second-order wave generation theory for dynamic wave force and run-up on a vertical wall in shallow to intermediate water depth (k<sub>0</sub>d=0.5−1...journal article 2023

Borja Rosales, L.P. (author), Scherpen, Jacquelien M.A. (author), Fujimoto, Kenji (author)In this article, we treat extended balancing for continuous-time linear time-invariant systems. We take a dissipativity perspective, thus, resulting in a characterization in terms of linear matrix inequalities. This perspective is useful for determining a priori error bounds. In addition, we address the problem of structure-preserving model...journal article 2023

de Wit, F.P. (author)When waves propagate towards the coast, nonlinear interactions occur under the influence of decreasing water depth and variable ambient currents. This changes the initially harmonic wave shape into a nonlinear wave shape due to the presence of bound waves accompanying the freely propagating primary waves. The nonlinear wave shape ranges from...doctoral thesis 2022

Chimmalgi, S. (author)Due to the ever increasing global connectivity, the demand on the fiber-optic communication infrastructure is projected to keep increasing rapidly. A major factor currently limiting transmission capacity is the fiber nonlinearity. Some researchers have suggested the application of nonlinear Fourier transforms to exploit the fiber nonlinearity...doctoral thesis 2022

Hafkemeyer, Linus (author)As more and more aspects of our society and economy rely on software, security vulnerabilities in programs have become an increasingly significant threat. One such class of vulnerabilities are out-of-bounds writes, which are still one of the most widespread and dangerous types of security bugs in memory-unsafe programming languages five decades...master thesis 2022

de Albuquerque Gleizer, G. (author)Event-triggered control (ETC) and self-triggered control (STC) are sample-and-hold control paradigms in which sensor data is only updated to the controller when necessary, often aperiodically, in contrast to the well-established periodic sampling paradigm. In ETC, a state-dependent event triggers a transmission, while in STC the controller...doctoral thesis 2022

Nambur Ramamohan, K. (author)Microphones are the most popular devices used to convert sound into electrical signals. However, with the advent of sensor technology, transducers capable of measuring vector quantities are opening up many new possibilities. One such device is an acoustic vector sensor (AVS), which measures both acoustic pressure and particle velocity, and has...doctoral thesis 2022

Toledo Farrando, Oscar (author)Reduced-order models (ROMs) are commonly used to reduce the complexity of large-scale fluid dynamics problems. The main technique to obtain their basis is proper orthogonal decomposition (POD), where an energy-based basis is obtained. Such a basis is derived without considering the governing equations. Moreover, if the flow dynamics are not...master thesis 2022

Xu, D. (author)Quantum computing is a flourishing field of scientific and technological research. The development of quantum computing in the past decades is the so-called second quantum revolution, where various aspects of quantum physics, such as entanglement and superposition, are used to form the main building block of computation — the quantum bit, or...doctoral thesis 2022

Westerborg, Ties (author)Learning to Rank is the application of Machine Learning in order to create and optimize ranking functions. Most Learning to Rank methods follow a listwise approach and optimize a listwise loss function which closely resembles the same metric used in the evaluation. Popular listwise loss functions such as nDCG, AP and nRBP do not have consistent...master thesis 2022

Wei, X. (author)This thesis addresses new methods and applications of ptychography which is a scanning Coherent Diffraction Imaging(CDI) method for reconstructing a complex valued object function from intensity measurements recorded in the Fraunhofer or Fresnel diffr- action region. The technique provides a solution to the so-called 'phase problem' and is found...doctoral thesis 2022

Wang, Ning (author), Wang, Ying (author), Wen, Guanghui (author), Lv, Maolong (author), Zhang, Fan (author)This article aims to realize event-triggered constrained consensus tracking for high-order nonlinear multiagent networks subject to full-state constraints. The main challenge of achieving such goals lies in the fact that the standard designs [e.g., backstepping, event-triggered control, and barrier Lyapunov functions (BLFs)] successfully...journal article 2022

Reniers, A.J.H.M. (author), Zijlema, M. (author)The Simulating WAves Nearshore (SWAN) model has been extended with an infragravity module to predict the Wave-Group-Forced (WGF) infragravity response to a frequency-directional sea-swell spectrum at a mildly sloping alongshore uniform beach. To that end the SWAN model has been extended with an WGF-infragravity source term denoted S<sub>sb<...journal article 2022

Kokke, C.A. (author), Coutino, Mario (author), Heusdens, R. (author), Leus, G.J.T. (author), Anitori, L. (author)Doppler velocity estimation in pulse-Doppler radar is done by evaluating the target returns of bursts of pulses. While this provides convenience and accuracy, it requires multiple pulses. In adaptive and cognitive radar systems, the ability to adapt on consecutive pulses, instead of bursts, brings potential performance benefits. Hence, with...conference paper 2022
