Being able to perform a press handstand is required to progress to more difficult techniques on almost every apparatus. Therefore it is recommended to learn this skill at an early age. The press handstand requires a combination of high strength, flexibility and motor skills all of which are valued abilities. …

A program that automatically detects auroral events in all-sky images taken by the all-sky camera of IRF has been written. Current programs that automatically detect the aurora in all-sky images using the RGB color system often miss strong aurora and sometimes interprets clouds as aurora. To improve …

Gas-phase diffusion is a widespread process in nature, for example diffusion of pollutants in the atmosphere. A special case of diffusion is the so-called Knudsen diffusion where a gas diffuses in the molecular flow regime. The theory for Knudsen diffusion is well-known therefore, diffusion experiments …

The purpose of this dissertation is to find out how Sanoma Media Netherlands B.V. is improving their customer engagement by using online native advertising. There are several measuring methods on how to examine the degree of customer engagement. The methods are based on the purpose of the advertisement. …

To date, limited research has been conducted on hydration in surfers and no recommendations could be found regarding optimal hydration practices in surfers. This makes it difficult for dietitians and surf coaches to give evidence-based advice to surfers regarding optimal hydration practices. In order …

Groeblacher Labs, at the TU Delft tries to achieve entanglement using optomechanical resonators like nanobeams. This is done by using the side peaks generated by the optomechanical resonators. These peaks are separated by 5 GHz in relation to the resonance peak of the optomechanical resonator. Because …

In this thesis the workings of a time-resolved setup are treated as well as the underlying physics. The setup is based on optical gating, which gives control over very short moments in time to let light pass through a gate. As this process is stable, light can be studied in very short and low intensities. …

Introduction Lateral trunk sway has never been assessed with an accelerometer in patients before and after total knee arthroplasty (TKA). Therefore, the purpose of this study is to determine the effect of a TKA-implant on lateral trunk sway amplitude with an accelerometer before and six weeks after TKA. Method …

The probation specialized in addiction problems controls and supports individuals with substance addiction who are sentenced or accused of crimes. The financial position of these individuals is often weak. Many have debts and a low income. Several studies show a positive correlation between a bad financial …

Previous researches have shown that there is a link between surface quality and equine performance and therewith potential injury risk. Therefore the question about optimal surface rises. But still comparable values and standardized measurement methods are missing. Therefore the aim of this research …
