Labaar, Derek (author)High-precision systems often comprise many individual systems, each operating at its own frequency. However, the vibrations from one system can be transmitted to another, which yields a response. In high-tech applications where precision is crucial, such as compliant transmission systems, these responses are undesired as they result in a loss in...master thesis 2024

Barth, R. (author)Genetic information encoded in the DNA sequences is maintained, replicated, and transcribed across the tree of life. Organisms evolved multiple hierarchical layers of chromosome organization which ensure that DNA can be contained but also processed within individual cells. This thesis focuses on SMC (Structural Maintenance of Chromosomes)...doctoral thesis 2024

Agrawal, Tanuj (author)Designing lightweight aircraft parts to improve fuel efficiency is crucial to meet the aviation sector’s goals of reducing CO2 emissions. However, it is also important to ensure that these lightweight parts have a lower CO2 footprint over their entire lifetime. Previous studies have successfully achieved this using topology optimization and low...master thesis 2024

Bagirov, Aslan (author)Structural design for unconventional aircraft can be quite challenging and could undergo<br/>many iterations until a solution is found for all load-cases such as static sizing, stability and<br/>crashworthiness. Ultimately, all of the design aspect are integrated in the earliest design<br/>changes for which Topology Optimization (TO) could...master thesis 2024

Hols, Jesse (author)Performance-driven generative design has been commonly used in engineering applications. In addition to performance metrics, aesthetics play an important role in the acceptance of generatively designed forms. When generating these shapes using generative programs, it is not clear in advance what the outcome will be, and thereby what they will...master thesis 2024

Splitthoff, L.J. (author)Superconducting circuits in cryogenic environments form an excellent material platform for the realization and study of quantum systems. <br/>In this thesis, we continue the exploration of novel types of circuit elements which expand the circuit quantum electrodynamics toolbox to enable exotic, and potentially better circuit implementations. To...doctoral thesis 2024

Garner, E. (author)Background: Despite over a century’s worth of technical improvements, the longterm survivability associated with orthopedic implants continues to fall short. In contrast to earlier designs, implant failure is no longer caused by structural failure of the implant itself. Rather, it results from the implant’s long-term detrimental effects on the...doctoral thesis 2024

Leban, Tilen (author)An investigation into the application of additive manufacturing to the production of structural joints was conducted for this thesis. The main goal was to determine all necessary aspects that someone needs to consider when designing a structural part that is intended to be printed with additive manufacturing. As an example, the branched column...master thesis 2024

Algra, Hendrik Jaap (author)The predominant influence of geometry and tensile stress on the Q factor of nanomechanical resonators is a phenomenon commonly described as dissipation dilution. In recent years, a variety of studies has looked into maximizing this effect, resulting in an assortment of softly-clamped resonator designs. This paper proposes a methodology that uses...master thesis 2024

de Groot, Patrick (author)Current service and installation activities for offshore wind turbines are carried out by jack-up vessels, which eliminate wave disturbances to a large extent. The use of these vessels imposes several disadvantages, including high operational costs and the limitation of operating in restricted water depths. An alternative is a crane mounted on a...master thesis 2024

Menger, Dehlia (author)Soft robots, characterised by compliant mechanisms (CMs) made from low-stiffness materials, offer improved adaptability compared to traditional, rigid robots. These CMs are often actuated by pressure loads. Moreover, soft robots provide new possibilities in the area of robotics. They can be used in search and rescue and interact safely in...master thesis 2024

van Bergen, Steven (author), Norte, R.A. (author), Aragon, A.M. (author)The computational analysis of nanophotonic devices is usually carried out via the standard finite element method (FEM). However, FEM requires meshes that are fitted to the devices’ boundaries, so making changes to the geometry (and thus the mesh) results in an inefficient process at best. Such an approach is therefore at odds when conducting...journal article 2024

Munro, D.P. (author)This note communicates a simple modification of the optimality criteria (OC) design update—as found in well-known Matlab implementations of the classical topology design problem—to an update based on a quadratic program (QP) with a single linear constraint. This QP update is a special case of the dual of Falk, which in general accommodates...journal article 2024

Baqershahi, Mohammad Hassan (author), Ayas, C. (author), Ghafoori, Elyas (author)Wire arc additive manufacturing (WAAM) enables the manufacturing of efficient and lightweight structural elements in which material can be utilised wherever needed in an optimised shape, in contrast to standard prismatic profiles used in construction. However, the specific energy consumption (SEC) of WAAM is higher than that of conventional...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

Oval, R. (author), Mesnil, Romain (author), van Mele, Tom (author), Baverel, Olivier (author), Block, Philippe (author)Several structural systems rely on a specific hierarchy between their constitutive elements, which results in topological constraints on the feasible patterns that can describe them. Folded, corrugated, or creased surface structures require this bipartition, also called two-colouring, between independent wavy and smooth directions. Finding a...journal article 2024
