Production of a newly discovered PHA family member with an isobutyrate-fed enrichment culture

Abstract: Using microbial enrichment cultures for the production of waste-derived polyhydroxyalkanoates (PHAs) is a promising technology to recover secondary resources. Volatile fatty acids (VFAs) form the preferred substrate for PHA production. Isobutyrate is a VFA appearing in multiple waste valorization routes, such as anaerobic...

A crisis that triggered change: How the Corona crisis impacted (aspiring) homeowners’ housing preferences: A study into possible change of housing preferences of (aspiring) owner-occupiers in the Netherlands resulting from the Covid-19 crisis, as to give insight into the lasting impact on future demand for the housing stock

The Corona crisis highly affected socio-economic circumstances, and this was expected to have changed housing preferences. Understanding what needs to be built in quality in addition to quantity is key to a sustainable housing market. Hence, this thesis researched whether and how housing preferences of (aspiring) owner occupiers in the Dutch...

Exploring the Potential of Performance Bounds in Multi-Source Domain Adaptation

Currently, trained machine learning models are readily available, but their training data might not be (for example due to privacy reasons). This thesis investigates how pre-trained models can be combined for performance on all their source domains, without access to data. This problem is formulated as a Multiple-Source Domain Adaptation (MSA)...

Gear Repair using Laser Metal Deposition

The urge for more sustainable and cost-efficient repair methods for damaged parts is growing every day. On the other hand, laser metal deposition (LMD) is gaining momentum. This flexible technique, where material is added in a layer-by-layer fashion with a minimal heat input offers solutions for a wide range of production and repair purposes....

Digital Control in a Motional Feedback Audio System

The quality of a loudspeaker system is largely determined by the distortion of the output signal, resulting from the non-ideal transfer of the loudspeaker and amplifier. This report proposes a method of reducing the distortion in the output signal by using a topology with active feedback. The feedback control unit, which is implemented by a...

Verslag van de wetenschappelijke reis naar Ligurië, Noord-Italië, door A.C.A. van Zutphen, W.A. van Wamel en A.J. Bons, maart/april 1984

In het voorjaar van 1984 werd een tiendaagse wetenschappelijke reis gemaakt naar het gebied ten noorden van Chiavari, Ligurië, Noord Apennijnen, Italië. In het kader van het onderzoeksproject van de Vakgroep Structurele en Toegepaste Geologie naar de opbouw van de Liguride Apennijnen wordt gewerkt aan een geotraverse van Rapallo in het...
