Andrade Borges, Emilia (author)
This thesis addresses the topic of ongoing (excessive) deformations observed in balanced cantilever prestressed concrete bridges all over the world. Many authors attribute this behavior to the time-dependent phenomena of creep and shrinkage. Balanced cantilever bridges are classified as creep-sensitive structures, and for that reason, a detailed...

Vibration attenuation in lightly damped blade-like systems such as cantilevers or end-effectors of robot manipulators can be dampened using Active Vibration Control (AVC). Piezoelectric patches in a collocated setup measure and control the bending modes of such a cantilever system using Positive Position Feedback (PPF). Tuning methods for PPF...

Much research is conducted on the biomechanical properties of cells, particularly in cancer research. Cell stiffness and cell adhesion are two properties often studied, because they are important for the functioning of a cell. To study these properties, atomic force microscopy(AFM) is often used, using nanoindentation for stiffness analysis and...

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...

The processes that take place within cells are complex. Single-cell analysis is a method that is employed to gain further understanding of the working mechanisms on a single-cellular level. The controlled transport of substances through the cell membrane is important for studying the behaviour and responses of single living cells. Femtopipettes...

The objective of this research is to design and evaluate a new type of rolling gate for the Western lock (Westsluis) in Terneuzen, for which all sensitive and heavily loaded mechanical parts are both easily accessible and located above water. Having all mechanical parts above water not only makes them easier to inspect and maintain, but it also...

Facioscapulohumeral muscle dystrophy (FSHD) is the third most common muscle disease in the world. No cure has been found for FSHD, and current treatments focus on alleviating the symptoms. The disease is caused by a genetic error in 1/1000 - 1/200 of the nuclei in a multinucleated skeletal muscle cell. Studying that specific nucleus, by removing...

In connection with growing in applications of nanoparticles in various industrial sectors such as cosmetics and pharmaceuticals, the demand for in-line identification and characterization of nanoparticles suspended in fluids has increased. In addition to that, nanoparticles in general and nanoplastics in particular, can easily contaminate air...

Damping vibrations of flexible structures is a subject of importance in several industries, as the aerospace and high-tech industry. Especially when the ratio of damping over weight needs to be high. In literature optimization of this ratio is achieved in several manners, through optimization of individual damping methods, ie. active and passive...

Project Orbit is a masterplan to fundamentally change the closed of relationship between the residential area of the Second Avenue and the medical area along the First Avenue in Midtown, New York. The project is comprised of the creation of a public plaza with a subway station and leisure uses; the repurposing of two listed buildings, for...

Piezoelectric vibration energy harvesting can provide a sustainable source of <br/>energy for low-power sensors. The vibrational energy is converted to electrical energy by piezoceramic cantilevers. Replacing batteries by vibrational energy harvesters, reduces the footprint of the device and no continuous replacement of batteries is required...

In this thesis, research is performed into parametric design of balanced cantilever bridges within the total road design. The main research question is: What can be achieved by using a parametric model in the preliminary design phase, with the possibility to optimize and compare concrete bridges on material usage, costs and environmental impact?...

Kramer, Robert (author)
Suspended hollow micro-cantilevers have been employed for zeptogram (10^-21 g) mass measurements, pipetting of femtoliter<br/>(10^-15 L) volumes, and studies on mechanical interaction with single cells. The main fabrication method of these devices is by standard clean room micro/nano fabrication techniques, however, they are inherently planar,...

Micro and Nano-mechanical resonators are becoming increasingly ubiquitous in the areas of particle characterization and biological sensing. For biological sensing, however, the presence of a liquid environment is a pre-requisite. Hollow cantilevers, which allow fluids to be transported inside the resonator, often have high quality factors even...

Huigsloot, Menno (author)
High performance machines such as those used in the semiconductor industry, robotics or racing engines have lots of fast moving parts. The dynamic properties of these moving parts are crucial to the performance of the machine. Therefore these moving parts have to be carefully designed which is often a very time consuming iterative process. In...

To facilitate research on the dynamics of micro-cantilevers immersed in liquid, a modal test setup was designed. Modal testing is a powerful form of dynamic testing whereby the system's natural frequencies, modal masses, modal damping ratios, mode shapes, and weight of each of these modes at a certain frequency are determined. Micro-cantilever...

The choice on which cantilever to use for Atomic Force Microscopy (AFM) depends on the type of the experiment being done. Usually, the cantilevers have to be exchanged when a different stiffness is required and the entire alignment has to be repeated. In the present work, we have developed a method to adjust the stiffness of the AFM cantilever...

The subject discussed in this thesis is the dosing of droplets in the femto (10-15) liter range. In this study, droplets were dispensed using a hollow cantilever atomic force microscope (AFM). Dispensing small volumes finds its applications in for example in single cell manipulation, where a drug is delivered inside a single cell to study the...
