van der Heiden, Luka (author)The behaviour of the dilute Curie-Weiss model has been analysed for Gaussian, bounded and subGaussian couplings. This model is an abstraction of the Curie-Weiss model which is a model of a spin configuration where instead of a constant coupling between spins the spin coupling is a realisation of a random variable. To analyse this behaviour first...bachelor thesis 2022

Rejali, R. (author)This thesis focuses on possible platforms for a bottom-up approach towards realizing and characterizing atomically assembled magnetic and electronic artificial lattices. For this, we make use of the scanning tunneling microscope (STM), which provides a local probe of the magnetic and electronic properties of the sample and allows for the atom-by...doctoral thesis 2022

Gan, Y. (author)Ageing is an inherent feature of cementitious materials. Ageing of material leads to gradual loss of the function of a concrete structure with increasing likelihood of failure. As one of the typical ageing phenomena, fatigue of concrete, has recently received considerable research attention. The phenomenon of concrete fatigue is complicated as...doctoral thesis 2022

Arens, Patricia (author)In the last decades there has been an increasing interest in computing the local strain at the atomic scale of materials. By knowing aspects of the local strain in a lattice, one has information about measurements of distortions of lattice parameters concerning shifts, deformations and defects computed with respect to a smooth, defect-free...bachelor thesis 2022

Wrzosek, Filip (author)A series of critical transmission lattice towers failures due to severe ice and wind loads forced German utility companies to reassess the structural stability of their power grid infrastructure. During the structural reassessment process, a problem related to an outdated or even missing documentation of the in-use infrastructure occurred. This...master thesis 2022

Schouten, Aron (author)Context: In astronomy, collision detection is the computational problem of finding when planets, asteroids or satellites collide. Computer simulations make it possible to show very precisely how bodies move through space, which makes it possible to detect collisions. However, these simulations require a lot of computing power if there are many...bachelor thesis 2022

Zegers, Samuel (author)In several experiments, enzymes have shown an in increase in diffusivity in the presence of their substrate. The enhancement in diffusivity ranged from as low as 28% for urease to 80% in the case of alkaline phosphatase. There are two main competing theories. One asserts that catalytically driven boosts propel the enzyme forward in ‘leaps’,...bachelor thesis 2022

van Elsloo, Sam (author)The Lattice Boltzmann Method (LBM) is an appealing framework to apply to unsteady, incompressible, low Reynolds number flow due to its simplicity and potential for massive parallelisation. The immersed boundary method is often used in conjunction with the LBM to simulate flow around curved, moving boundaries in the interior of the fluid domain....master thesis 2022

Kuipers, T. (author)The products in our day to day lives have different requirements in different regions of the product. One way of dealing with such spatially varying requirements is to divide the product into multiple parts and assign each part a different material. For example, the handle of a drill is often fitted with a rubbery material which gives it more...doctoral thesis 2022

Verhagen, Luuk (author)The potential for the production of green energy in the Netherlands is insufficiently utilized. The cause for this problem is the insufficient bearing capacity of industrial roofs for the installation of solar panels using ballast. This required ballast exceeds the bearing capacity of the roof structure, or exceeds the bearing capacity of the...master thesis 2022

Teruna, C. (author)Public annoyances due to noise emission in aviation and wind energy sectors are expected to become more severe in the near future with increasing number of civilian flights and wind turbine installations. Such trend demands for deeper investigations into the noise generation mechanisms and the means to mitigate them. This dissertation addresses...doctoral thesis 2022

van Megen, Demi (author)In recent studies, selection criteria for lattice materials suitable for active shape-morphing have been composed. These criteria have directly resulted in the proposal of a lattice that is able to compete with the Kagome lattice, which in the literature is identified as a lattice material with optimal in-plane stiffness and shape-morphing...master thesis 2022

van Thiel, T.C. (author)Modern materials synthesis techniques allowfor the layer-by-layer assimilation of structurally similar, yet compositionally different materials into artificial crystals, with atomic scale precision. At the resulting heterointerfaces, structural, electronic and magnetic reconstructions can lead to physical phenomena that are otherwise absent in...doctoral thesis 2022

Romani, G. (author), Grande, E. (author), Avallone, F. (author), Ragni, D. (author), Casalino, D. (author)This paper presents a computational study of flow incidence effects on the aeroacoustics of a propeller operating at low blade-tip Mach numbers. The numerical flow solution is obtained by using the Lattice-Boltzmann/Very Large Eddy Simulation method, while far-field noise is computed through the Ffowcs-Williams & Hawkings' acoustic...journal article 2022

Chazottes, Jean-René (author), Redig, F.H.J. (author)For a general class of lattice spin systems, we prove that an abstract Gaussian concentration bound implies positivity of the lower relative entropy density. As a consequence, we obtain uniqueness of translation-invariant Gibbs measures from the Gaussian concentration bound in this general setting. This extends earlier results with a different...journal article 2022
