A hygiene ventilation renovation: Systematic partial engineering control for small sharing room with ceiling mixing ventilation for “corona-proof”

Efficient local air recirculation at ceiling level promote the performance of purifiers and anti-epidemic efficiency of mixing ventilation in a small shared rooms

Improving the sensitivity of piezoelectric composites by adding porosity

Piezoelectric materials have the ability to convert mechanical to electrical energy (direct effect) and vice versa. They are readily used in the aerospace, automobile, telecommunication industry etc. as both sensors and actuators. For this work the focus is on the sensor application, which utilizes the direct piezoelectric effect. With the...

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...

Operating Room Scheduling during COVID-19: An advice on planning models in the Reinier de Graaf hospital

During the first COVID-19 wave in the Netherlands, hospitals had to scale down their elective care all over the hospital to make room for COVID-19 patients. Even the Operating Room (OR) reduced their surgeries to acute care. It is, however, hard to define how much the OR should downscale. Also, there are no national plans on how hospitals should...

Daily family routines after Corona times

The COVID-19 pandemic had a major impact on the daily routines of families in the Netherlands. From March 2020, strict measures were taken by the government to prevent the spread of the virus; The Dutch population was under quarantine. This caused many changes in the everyday life of families. Using an exploratory process with six families,...

Public Transport during coronavirus outbreak: A research of measures taken in Dutch and international PT

In 2019 a virus surfaced in China that would later cause a pandemic: the coronavirus. Across the world measures were taken to reduce the spread of the virus. Public Transport (PT) had a unique position, being both an essential service and a place where the virus can easily be spread. This research investigates the measures taken in PT in the...

Investigation of Passivating Layers in c-Si Solar Cells Using a Corona Charging System

There are two existing surface passivation principles. Passivation of unsaturated Si bonds is called chemical passivation. Surface passivation can also be achieved by shielding the minority charge carriers from the semiconductor interface by means of an electric field. This method is referred to as field-effect passivation. <br/>To test the...

Partial Discharge Analysis in HVDC Gas Insulated Substations

Nowadays, Gas Insulated Substations (GIS) are vital nodes of the Transmission Network due to their compact dimensions permitted by the use of SF6 as insulating medium and the high reliability guaranteed. Nonetheless, the strictly requirements of safety in operation and continuous power supply catalyse the attention to improve the reliability and...
