Condition monitoring of railway transition zones through axle box accelerations using multi body simulation software

Transition zones in railway tracks are locations with an abrupt change in stiffness in the vertical rail supporting structure. These locations are typically located as approaches near engineering structures where there is a sudden change in track substructure. Due to these abrupt changes the dynamic forces of the wheel-rail interaction on the...

The effect of aeration on the maximum pressure during wave impacts on a horizontal overhang: An experimental and numerical study of the effect of aeration on the maximum impact on a horizontal overhang.

When waves break, air and water mix and small air bubbles are formed in the water, creating aeration. The mixture of air and water alters the behavior of the fluid. Traditionally, it has been assumed that aeration has a damping effect on impact, as exemplified by the use of air bubbles in the swimming pool below the Olympic 10m platform and...

The effect of cognitive load on the effect of external Human-Machine Interfaces: An eye-tracker experiment

With the increase in development of self-driving cars, research has been conducted to retain humanized interaction between cars and other road users, such as pedestrians. One way to retain this type of interaction is through the use of external Human-Machine Interfaces (eHMIs). This project aims to contribute to this field of research by...

Interventions for an inclusive energy transition in Amsterdam Zuidoost: An ethnographic research on inclusivity of the LIFE project

In order to overcome the existential threat of climate change the energy transition is needed. The energy transition has multiple challenges, one of them being that it risks increasing inequality. This challenge also occurs in Amsterdam Zuidoost. In Amsterdam Zuidoost almost one out of five households lives already in energy poverty, which risks...

Water surface heights in the upper Brahmaputra and Nam Co basin with ICESat-2

Due to climate change, glaciers are melting on the Tibetan Plateau. These glaciers are the water source for big rivers as the Brahmaputra which stream towards the most densely populated area on Earth. Previous studies indicated that water surface heights of lakes connected to the glaciers are increasing in the north of the Tibetan Plateau, while...

Improving the perception of waiting time through positive interactions at the G-gates of Schiphol

To achieve the ambition of providing a 9+ experience for every passenger, the Passenger Experience Platform develops concepts that improve on impactful touchpoints of the passenger journey. Increasing the passenger satisfaction contributes to the ambition of Schiphol to become Europe’s preferred airport. The departure gates are impactful...

The Integration of Diffuse Reflectance Spectroscopy into the Electrosurgical Knife: Clarifying and Preventing Diffuse Reflectance Spectroscopy Signal Deterioration during Use of the Smart Electrosurgical Knife

During use of the smart electrosurgical knife, deterioration of the diffuse reflectance spectroscopy (DRS) signal intensity obstructs proper distinction between tissues. In order to reduce signal loss, this research has focused on the influence of smart electrosurgery on both the morphology and composition of the layer covering the optical fiber...
