Bechtel, S. (author)We show L<sup>p</sup>-estimates for square roots of second order complex elliptic systems L in divergence form on open sets in R<sup>d</sup> subject to mixed boundary conditions. The underlying set is supposed to be locally uniform near the Neumann boundary part, and the Dirichlet boundary part is Ahlfors–David regular. The lower endpoint for...journal article 2024

Zhai, X. (author), Wang, Weiming (author), Chen, Falai (author), Wu, J. (author)Recent years have seen a growing interest in topology optimization of functionally graded microstructures, characterized by an array of microstructures with varying volume fractions. However, microstructures optimized at slightly different volume fractions do not necessarily connect well when placed adjacently. Furthermore, optimization is...journal article 2024

Hsu, Hsing-Li (author)Reset controllers are acknowledged for their potential to enhance performance, like speed and precision in precision motion industries. Existing literature primarily utilizes the classical zero-crossing law in these controllers. This study introduces a novel reset component, termed “fixed-phase reset control”, which employs an innovative reset...master thesis 2023

Wei, Z. (author)Photoinduced charge transfer (CT) is a fundamental photophysical process that prevails in nature but also plays a pivotal role in various technological fields. This thesis describes spectroscopic studies on photoinduced CT in donor-bridge-acceptor (DBA) systems and their derivatives. Throughout this work, we employ femtosecond transient...doctoral thesis 2023

Alaka, Shaad (author)Virtual worlds are rapidly increasing in size, enabled by advancements in computing technology, which puts a large burden on designers creating them.<br/>Procedural Content Generation can help alleviate this burden, though lacks precise control, to the detriment of designer intent. Some PCG algorithms, such as Wave Function Collapse (WFC), known...master thesis 2023

Jankie, julia (author)Macaulay's method utilizes singularity functions to describe discontinue forces acting on beam structures. This method has been extended to determine internal forces and influence lines, making use of a single expression. The method can be applied to analyze all possible scenarios for both one-dimensional and two-dimensional constructions.bachelor thesis 2023

Golchin, A. (author)In the serviceability lifespan of thermo-active geo-structures such as energy-piles, soils surrounding these structures are exposed to a combination of mechanical and thermal loads. These loads are often complex (including cycles) and, depending on the state of the soils, the response of the surrounding soil to these loads may differ. Since the...doctoral thesis 2023

Alboustani, Tarik (author)System Design in the built environment is one of the most influential design paradigms in architecture and construction. This paper seeks to amalgamate empirical design strategies with various architectural principles, including the notion of “open buildings” or “open-ended architecture,” as well as Structuralism, all within a computational...master thesis 2023

de Vries, Rinto (author)Recent literature in real-time trajectory planning has proposed using Control Barrier Functions (CBFs) as collision constraints in Model Predictive Control (MPC) for efficient guidance, a concept referred to as MPC-CBF. This concept has been explored for both first and second-order CBFs. However, these approaches relied on an analytical...master thesis 2023

van Veldhuijzen, Emiel (author)Advancements in radar technology such as phased array antennas, digital beamforming, and adaptable waveform generation have led to the flexibility in controlling radar resources such as scan time, beamwidth and bandwidth during a radar mission. This new flexibility has led to a new research topic, radar resource management. Radar resource...master thesis 2023

Corak, Nino (author)One possible way of proving the famous and important Riemann hypothesis would be to realize the Riemann zeta zeroes as the eigenvalues of some self-adjoint operator, using self-adjointness to show that the non-trivial zeroes all lie on the critical line. This is known as the Hilbert-Polya conjecture. Interpreting such a self-adjoint operator as...bachelor thesis 2023

PAN, ZHE-HONG (author)In recent times, soft matter has gained significant interest among researchers in the fields of biomechanics and biomedicine, especially in areas like soft robotics and biopolymers, due to its remarkable ability to undergo substantial deformations. Soft robotics often requires materials that can flexibly adapt to or mimic the movements of living...master thesis 2023

Lohar, Nivedita (author)In 2022, there were over 26 million electric automobiles on the road, a 60% increase with regard to 2021 and more than 5 times the stock in 2018. As automobiles become more electric and systems get increasingly complex, the safety requirements get more stringent. In 2011, the International Organization for Standardization (ISO) established...master thesis 2023

Cazier, Jordi (author)The solute transport across the osteochondral (OC) interface is of crucial metabolic importance for a normal function of articular cartilage, and, therefore, for the OC interface as a whole. A better understanding how the mechanical- and physiological properties of the OC interface affect the solute transport across the OC interface could lead...master thesis 2023

van der Kaaij, Daniek (author)Introduction: High cardiovascular mortality primarily limits survival following kidney transplantation (KTx). The increased risk is intrinsically connected to cardiac structural and functional abnormalities. LV volumetric imaging measurements are used to quantify this, such as left ventricular ejection fraction (LVEF) and left ventricular end...master thesis 2023

Lubbers, Seymour (author)Greenhouses allow production of crops that would otherwise be impossible. Permitting more local, fresher and nutrient richer crop production. Eorts are taken to minimize societal harm due to energy and resource consumption by greenhouse production systems. One way to control such systems is by using model predictive control. Optimal crop yield...master thesis 2023
