Ultrafiltration (UF) is an efficient and effective method of filtrating oil-in-water (O/W) emulsions. However, the favorable conditions of filtrating nano-sized O/W emulsions have not been investigated. This study investigated the influence of four different parameters including membrane pore size, cross flow velocity, pH and salinity on...

Narchi, William (author)
This paper presents how a convolutional neural network can be constructed in order to recognise gestures using photodiodes and ambient light. A number of candidates are presented and evaluated, with the most performant being adopted for in-depth analysis. This network is then compressed in order to be ran on an Arduino Nano 33 BLE...

Public technology has been shown to have a strong dependence on physical touch, which increases the transmission of diseases. Gesture recognition helps to reduce this transmission, as the dependence on physical touch is removed. Furthermore, the use of visible light for gesture recognition would reduce the power consumption of public technology,...

Low downlink data rates limit the scientific and commercial return from small satellites. Now with constellations of small satellites becoming popular, the amount of data generated in low Earth orbit will be greater than ever. A novel data downlink architecture for small satellites is investigated that uses non-geostationary orbit (mega-...

The goal of the research described in this thesis was to investigate the basis of dissipation dilution as well as make it comprehensible. In the written literature we could find that the kinetic energy of an oscillating beam is stored into two types of potential energy~\cite{Kippenberg, Kotthaus}. A dissipative bending component and a...

Having an absorber layer thickness below 1 micrometre for a regular copper indium gallium di-selenide (CIGS) solar cell reduces the pathways for electron collection which lead to reduced recombination in the bulk absorber layer. Additionally, it reduces material costs and production time. Yet, having such a thin absorber reduces the cell...
