Nuri, Masi (author)Cracks that develop in concrete due to tensile stresses can lead to the corrosion of embedded reinforcing steel, which is a primary cause of concrete deterioration. It's common practice to introduce additional reinforcement to limit crack width in concrete. Another potential solution involves partially substituting concrete with alternative...master thesis 2023

Amoozandeh, A. (author)Industrial passive exoskeletons have been developed for years as a tool to reduce the physical workload of their users. They accomplish this by compensating for the user’s body weight and decreasing fatigue caused by repetitive loads. Despite their advantages, current exoskeletons have drawbacks that make them less convenient for users and thus...doctoral thesis 2023

van Rooij, Nils (author)With the building and construction sector accounting for a significant portion of final energy use and emissions, and society’s increasing focus on environmental awareness and improvements, the impor- tance of sustainable construction has never been greater. The utilisation of timber in construction offers clear sustainability benefits and has...master thesis 2023

Köroğlu, Ege (author)In this Masters thesis, the dynamics of pipes conveying pulsating flow are investigated. The initial-boundary value problem associated with the linear beam equations of motions governing the pipe system is derived using the principles of Lagrangian mechanics. In this thesis, the fluid flow is assumed to have a small velocity with harmonic time...master thesis 2023

van den Broek, Ruben (author)Introduction Holland PTC (Delft, The Netherlands) is an independent outpatient clinic where ten different types of cancer are treated with Pencil Beam Scanning (PBS). Some of these cancer types are situated in the thoracic region and therefore exposed to breathing motion. The interplay between the dynamic pencil beam delivered in PBS and the...master thesis 2023

de Bruin, Arnoud (author)International and local legislation on emission reduction urge the Dutch beam trawler fleet to reduce the use of fossil fuels. In 2015 the United Nations Paris Agreement was signed and as a result IMO and EU set the objective to reduce the GHG or CO2 emissions of the shipping industry. The Dutch beam trawler<br/>has been confronted with many...master thesis 2023

Zhao, Changxu (author)With the development of the fifth generation (5G) technologies and beyond, the requirements for future wireless communication systems become more stringent, which demand novel antenna design at millimetre waves. The most commonly proposed array topology for 5G usage is square 8x8 or 16x16 microstrip patches with the full digital beam-forming...master thesis 2023

Hoogenberg, Friso (author)Gravitational waves predicted by Einstein have been measured in a few observatories worldwide. These detectors are complex interferometers with sizes of kilometers. Misalignments and aberrations in their optical set-up can create higher-order modes in the laser beam. These higher-order mode effects should be compensated to improve the...master thesis 2023

Frijns, Jesper (author)Laser satellite communications for ground-to-ground and ground-to space links is influenced by atmospheric turbulence. Typically, theoretical models are used to predict link performance and the influence of the atmosphere on variables such as beam wander, spot size and scintillation at the receiver. These variables are used as input for system...master thesis 2023

Kisoensingh, Arvind (author)Flexural shear failure is a brittle failure mode that can occur in reinforced concrete (RC) beams without stirrups due to the combination of flexural and shear stresses. The failure mode begins with vertical flexural cracks at the bottom of the RC beam central span area due to flexural tensile stresses, followed by diagonal cracks. During...master thesis 2023

Moens, Tieme (author)Flying drones have been a well-established field of engineering for many years now. With the wave of bio-inspired design came the idea of flapping wing micro air vehicles (FWMAVs). These drones use flapping wings instead of fixed or rotary wings to generate their lift, giving them the potential for agile movement and application in confined...master thesis 2023

Streng, Robin (author)Nowadays, Rijkswaterstaat reassesses many older concrete bridges to guarantee their structural safety under the influence of increased traffic loads and stricter standards. Many of these concrete bridges contain open straight-legged stirrups, which are not allowed to take into account for the calculations of the shear resistance according to...master thesis 2023

Weiler, Marnix (author)During ‘float-out’ installation of export cables, the cable is pulled to shore while floating, supported by inflatable floaters. Understanding the hydrodynamic behaviour of these cable-floater-systems (CFS’s) is important, to be able to relate the hydraulic environment to the cable stresses and determine the maximum allowed hydraulic conditions...master thesis 2023

van der Vis, Max (author)Research has shown concepts of phononic integrated circuits (PnICs) consisting of multiple acoustic waveguides and beam splitters. Traveling acoustic waves experience energy loss when moving. Minimizing these losses is critical for large and complex PnICs. By fabricating on-chip PnICs, it is possible to operate under vacuum and at low...master thesis 2023

Bosma, S. (author)Millimeter- and submillimeter wave applications, such as point-to-point wireless communications in beyond-5G scenarios, long-range automotive radars and astronomy and astrophysics science cases from space require antennas with high-gain beams that are steerable. At lower (microwave) frequencies, fully sampled phased arrays with thousands of...doctoral thesis 2023

Budnik, Bartosz (author)Strain Hardening Cementitious Composite (SHCC) is an innovative type of fibre-reinforced cement-based composite that has superior tensile properties. Because of this, it holds the potential to enhance the shear capacity of reinforced concrete (RC) beams, if applied properly.<br/><br/>Experimental research was thus carried out with the purpose of...master thesis 2023

Cupać, Jagoda (author), Louter, P.C. (author), Nussbaumer, Alain (author)In the evolution of structural glass beam elements, the requirements for post-fracture load bearing capacity and safe failure behaviour have led to the development of reinforced and post-tensioned beams. Maximum bending capacity in the post-fracture state is normally associated with extensive yielding of the reinforcement, providing a safe...journal article 2023

Amoozandeh, A. (author), Radaelli, G. (author), Herder, J.L. (author)A cantilevered rod's endpoint has a symmetric stiffness profile throughout its range of motion. Generally, this is not the case for spatially curved compliant beams, particularly if they are asymmetric, i.e., their fixation is not in the symmetry plane of their endpoint operating field. This paper discusses a technique for obtaining symmetric...journal article 2023

Robin, M.P. (author), Guis, R.H. (author), Arabul, Mustafa Umit (author), Zhou, Zili (author), Pandey, Nitesh (author), Verbiest, G.J. (author)Conoscopic interferometry is a promising detection technique for ultrafast acoustics. By focusing a probe beam through a birefringent crystal before passing it through a polarizer, conoscopic interferences sculpt the spatial profile of the beam. The use of these patterns for acoustic wave detection revealed a higher detection sensitivity over...journal article 2023
