Zdziarska, Kika (author)This project presents a response to the pressing issue of women's safety in public spaces, particularly in Latin American cities. Women worldwide are disproportionately affected by safety issues and fear in urban environments. I explore ways in which public spaces can enhance perceptions of safety and freedom instead. Based on extensive four...master thesis 2024

Xu, Hongxin (author)Strong intergenerational relationships can provide emotional support and stability for both grandparents and grandchildren. Technology tools have been proven to be beneficial in connecting grandchildren and grandparents. Prior work mainly examined how to use technology to connect children and their grandparents over a distance. Those collocated...master thesis 2024

Rutten, Jurriaan (author)This thesis presents a novel approach to the pricing of green bonds, a growing segment in financial markets with an emphasis on environmental sustainability. Unlike traditional financial instruments, green bonds uniquely incorporate environmental considerations, particularly carbon price (c_t), along with traditional factors like the short rate ...master thesis 2024

He, P. (author), Moreira Arouche, M. (author), Koetsier, M. (author), Pavlovic, M. (author)Debonding is characterized as the governing failure mode in the innovative wrapped composite joints made with glass fiber composite material wrapped around steel hollow sections without welding. The prerequisite for predicting debonding failure of wrapped composite joints is to obtain fracture behavior of the composite-steel bonded interface....journal article 2024

Wang, Xintu (author), Xu, Yanghui (author), Ou, Q. (author), Chen, Wenwen (author), van der Meer, W.G.J. (author), Liu, G. (author)The excessive use and accumulation of water-soluble polymers (WSPs, known as “liquid plastics”) in the environment can pose potential risks to both ecosystems and human health, but the environmental fate of WSPs remains unclear. Here, the adsorption behavior of WSPs with different molecular weight on kaolinite (Kaol) and montmorillonite (Mt)...journal article 2024

PRABHAKHARAN, ASHWINRAJ (author)Hermeticity is a measure of how well a package is leak-tight. Many Micro-Electro-Mechanical Systems (MEMS) sensors, actuators, and microelectronic devices need a defined cavity environment for optimal performance, hence measuring the package leak rate is critical for lifetime prediction. MEMS devices are generally packaged through the wafer...master thesis 2023

Puthukattil, Rahul (author)This thesis investigates the application of force control techniques to enhance industrial wire bonding processes. It entails the design of a simulation model for the Z-axis interaction between bondhead and environment, followed by the implementation of a Parallel Force Control architecture in Simulink. The study evaluates different force and...master thesis 2023

Liu, Yixuan (author)Linear time-invariant (LTI) controllers suffer from inherent limitations as the waterbed effect and Bode's gain-phase relationship. Reset control, a nonlinear strategy involving the reset of linear controllers, offers a potential solution to overcome these traditional LTI limitations. Based on the describing function analysis, the reset...master thesis 2023

Poliakov, Mykyta (author)Fibre Metal Laminates (FMLs) have been widely utilised in aircraft structures for their specific strength, durability and damage tolerance. Most aircraft structures, due to their size, require joining, and FMLs allow for a special type of joint called the splice, a unique but a lesser known joint.<br/><br/>The bulk of research into the splice...master thesis 2023

Skarka, Michał (author)The concept of lightweight design is driving future aircraft to exploit all the available strength of materials and further reduce the weight of an aircraft leading to lower fuel consumption and more sustainable aviation. Current designs introduce rivets and bolts to join the structure and simultaneously create holes in the pristine material,...master thesis 2023

Mithapelli, Nitesh (author)Conventional construction techniques are unsustainable and expensive due to longer construction time, labour-intensive work, and the use of formwork. 3D concrete printing is seen as a potential substitute to overcome these issues. However, extrusion-based 3D printed structures exhibit a weak interlayer bond, and researchers have tried to address...master thesis 2023

Koel, Lars (author)A Helically wrapped structure is a hollow pipe structure that is made from a metal strip and the overlapping interfaces are adhesively joined. It is yet unknown how to determine the quasi-static strength and predict the fatigue life of this structure. A method was developed to determine whether either the adherend or the adhesive is critical to...master thesis 2023

Lenskens, Robin (author)Since the conception of the euro, it has often been suggested that the eurozone start a programme of jointly issuing government debt. There are many arguments for these so-called Eurobonds, and temporary issuance of them has already taken place in response to the economic impact of the recent COVID-19 pandemic. However, a permanent Eurobond...master thesis 2023

Westerbeek, Elise (author)Strain hardening cementitious composites (SHCC) can be used to reduce the amount of reinforcement needed to control crack widths. SHCC has a strain hardening behaviour with dense micro-cracking, which makes it more ductile compared to conventional concrete. Conventional concrete can be used in the non-critical locations. An interface is formed...master thesis 2023

Jongbloed, B.C.P. (author), Teuwen, Julie J.E. (author), Villegas, I.F. (author)Continuous ultrasonic welding is an attractive welding technique for thermoplastic composite structures. In this process, a metallic sonotrode connected to a piezoelectric transducer and to a press moves along the parts to be welded applying ultrasonic vibrations and a static welding force on the welding overlap. Thus far, the research carried...journal article 2023

Guevara Sotelo, N.S. (author), Villegas, I.F. (author)Ultrasonic welding is a fast and promising joining technique for thermoplastic composite parts. Understanding how changing the part thickness affects the process is crucial to its future upscaling and industrialization. This article presents an initial insight into the effect of the adherend’s thickness on the near-field ultrasonic welding of CF...journal article 2023
