Pulsed LED line light for large-scale PIV -development and use in wave load measurements

In this paper the development of a high-power pulsed LED line light and its use to apply particle image velocimetry (PIV) during wave impact measurements are described. An electrical circuit that generates high-current pulses is designed and built, which is used to overdrive a number of commercially available LEDs. The limit for this...

Smart Personal Protective Equipment: UVGI

The Smart Personal Protective Equipment (SPPE) is proposed as a result of the COVID-19 pandemic, which has led to shortages of standard face masks. This thesis describes one of the three subsystems of the SPPE, namely the Ultraviolet Germicidal Irradiation (UVGI). The UVGI subsystem provides the SPPE with an in situ disinfection system, in order...
