In dit onderzoek zijn de mogelijkheden onderzocht voor alternatieve manieren van daglichttransport in een schoolgebouw, omdat dit een positieve invloed op de werkprestaties heeft. Er zijn oplossingen beschreven om daglicht via een andere weg dan gevelopeningen een ruimte in te leiden zoals intelligente …

A system was designed and assembled to measure the critical temperature of superconductive thin niobium titanium nitride films. The films were produced via a process called sputtering. The parameters used during this process were characterized to produce films with as high as possible critical temperature …

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 …

Integrated photonic sensors are promising devices for various sensing applications due to their low cost, small size, and high sensitivities that can be reached. In this thesis, ring resonators and three-port Mach-Zehnder interferometer (MZI) devices fabricated on Silicon-On-Insulator were compared for …

The thermally-sensitive resistors (thermistors) used in VSL’s water calorimeter to detect the radiation-induced temperature change in water are affected by self-heat. The measurement current used to determine their resistance causes their temperature to increase above that of their environment. The self-heat …

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 …

Voor horecabezitters is het van belang om een zo goed mogelijke muziekbeleving meegegeven aan hun klanten zonder de klant hierbij te storen. De twee idealen botsen zo nu en dan. En niet alleen klanten willen ongestoord met elkaar kunnen praten, ook omwonenden willen geen last hebben van de muziek. Voor …

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. …

Cyanobacteriochromen (CBCR) zijn fytochroom-gerelateerde fotoreceptor eiwitten, die van eiwitstructuur veranderen wanneer deze belicht worden met bepaalde kleuren licht. Tijdens deze foto-conversie transformeren de CBCRs van de ene stabiele staat naar de andere, via het doorlopen van verschillende tussenproducten. …
