van Dijk, Bob (author)In the Netherlands, numerous bridges face reassessment. During this assessment, it is observed that in some cases, the applied shear reinforcement (stirrups) does not meet the detailing requirement given in the national annex of the NEN-EN 1992-2. This requirement, which states that the stirrups must enclose the longitudinal reinforcement to...master thesis 2024

van Daalen, Jippe (author)Currently, most of the modular building can be fabricated off-site, except for the stability system. Therefore, the question arises: Could modules be designed such that there is no need for an additional stability system? As modules are typically built in a rectangular shape, incorporating stability elements such as bracings along the longer...master thesis 2024

Kromwijk, Dominique (author)The integration of biological and (bio-)geochemical processes in soils is posed to become the next transformative practice in geotechnical engineering. Soil Sealing by Enhanced Aluminium and dissolved organic matter Leaching, also known as SoSEAL, is inspired by a natural soil formation process, called Podzolization. This process results in the...master thesis 2024

Della Pia, A. (author), Michelis, Theodorus (author), Chiatto, Matteo (author), Kotsonis, M. (author), De Luca, Luigi (author)This study reports the first time-resolved particle image velocimetry characterization of a planar two-phase mixing layer flow, whose velocity field is measured simultaneously in gas and liquid streams. Two parallel air and water flows meet downstream of a splitter plate, giving rise to an initially spanwise invariant configuration. The aim...journal article 2024

Manchester, Emily Louise (author), Pirola, S. (author), Pirola, Sergio (author), Mastroiacovo, Giorgio (author), Polvani, Gianluca (author), Pontone, Gianluca (author), Xu, Xiao Yun (author)Aortic valve disease is often treated with bioprosthetic valves. An alternative treatment is aortic valve neocuspidization which is a relatively new reparative procedure whereby the three aortic cusps are replaced with patient pericardium or bovine tissues. Recent research indicates that aortic blood flow is disturbed, and turbulence effects...journal article 2024

Bugeat, B. (author), Boldini, P.C. (author), Hasan, A.M. (author), Pecnik, Rene (author)This paper addresses the stability of plane Couette flow in the presence of strong density and viscosity stratifications. It demonstrates the existence of a generalised inflection point that satisfies the generalised Fjørtoft criterion of instability when a minimum of kinematic viscosity is present in the base flow. The characteristic scales...journal article 2024

Liu, Yanjing (author)Background: <br/>Ischemic stroke is a major cause of death worldwide. Atherosclerosis in the carotid arteries is an established predictor of these events. FSI shows its advantage in simulating the hemodynamic environments due to involving the multiphysics coupling of fluid dynamics and structural mechanics regulations. Therefore, the aim of this...master thesis 2023

Derks, Ivo (author)Both preloaded and injected bolted connections are commonly used in steel bridges in The Netherlands. Where preloaded bolted connections are already used for a longer time, the injection of bolt holes is a method used from the 1970s onwards. Injection of bolts became a good alternative for the replacement of riveted connections. This injection...master thesis 2023

de Juana Fabra, Amalia (author)Atherosclerosis is an arterial condition characterized by the accumulation mainly of lipid tissue, resulting in the narrowing and stiffening of arteries. It is the leading cause of death among cardiovascular diseases and its development has been associated with wall shear (WSS) and wall mechanical stress (WMS). This study aimed to analyse WSS...master thesis 2023

Firman Habib, F (author)Large-diameter monopiles serve as foundations for offshore wind turbines (OWT), and the diameters are now up to 10 meters. These monopiles exhibit lower embedded length-to-diameter (L/D) ratios compared to the conventional monopile that is widely employed in offshore oil and gas platforms. They undergo rotation when subjected to lateral loading...master thesis 2023

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

van Keulen, D.C. (author)The thixotropic properties of contemporary mortars allow the insertion of mortar in small vertical seams by using a mortar pump without the need for traditional formwork. In such a seam, a vertical mortar connection for the transfer of shear forces can be created by simply adding a profile to the mortar-to-concrete interfaces. In this way a...doctoral thesis 2023
