Micromechanical resonators, which have become feasible due to advanced manufacturing techniques, have shown several interesting phenomena including mode coupling in a range of applications that span metrology and sensing. Conventional fabrication methods of these resonators have been used throughout the field. However, fabrication of...

Mode coupling has extensive use in the MEMS field, including frequency division, vibration direction conversion, and energy transfer. In practice, these applications can be used to improve the performance of various devices such as sensors and energy harvesters. Nonlinear spring also has a wide application in MEMS field. Various nonlinear spring...

The comprehensive assessment of the deviatoric behaviour in peats is paramount in ensuring the resilience of soil structures. The understanding of this material is riddled with intricacies, given its highly complex fabric, which includes organic matter such as fibers. This thesis evaluates the capabilities of a recent constitutive model (JMC) to...

Alkali-activated material (AAM) is one of the most attractive alternatives to ordinary Portland cement (OPC). Recently, more and more research interests are devoted to durability performance. In cold areas, freeze-thaw resistance is a crucial durability factor for concrete. However, the understanding of the freeze-thaw resistance of AAMs is...

In het gebied Apeldoorn – Dieren ligt een oude spoorlijn van de Veluwsche Stoomtrein Maatschappij die op dit moment alleen nog voor toeristisch gebruik wordt geëxploiteerd. Om de bereikbaarheid van het gebied te vergroten wordt er onderzoek gedaan naar de mogelijkheid om hier een railgebonden voertuig op de introduceren. Dit leidt tot de vraag; ...

Rail wear in curves at the tramway of Amsterdam is a considerable problem since it consumes a significant part of the maintenance budget. The wear mechanism is not fully understood because some curves could suffer much more than others, while the cause for the difference is unknown. GVB, the public transport operator of Amsterdam, wants to...

Transport by rail has taken Europe by storm ever since their introduction in the 19th century. Developments in the past 150 years have led to the construction, deconstruction and reconstruction of various rail connections. In the Netherlands, a small number of lines in its more rural parts no longer have any standard passenger services and are...

The estimation of railway track parameters from a target frequency response function is a non-convex optimization problem. The objective of this thesis is to evaluate new evolutionary optimization methods to solve the railway track optimization problem. We use a Python based platform, since this programming language is increasing in popularity...

In floors without dilation joints drying shrinkage cracking can occur. Shrinkage reducing agents (SRAs) can reduce the amount of drying shrinkage and improve the durability of the concrete structure. The mechanism of shrinkage reduction and the influences on the hydration process and development of mechanical properties of the SRA Sika Control...

Sustainable railway systems with less disturbance are highly desired. Insulated rail joint (IRJ) is one important structural component in a railway track. IRJs serve the railway system with two crucial functions: dividing track into sections for signal control and enable the detection of broken rails. An IRJ generally consists of two fishplates,...
