This paper analyses Amsterdam’s Startup-in-Residence (SiR) programme as new type of policy to engage startups in the development of urban innovation through a challenge-based public procurement of innovation (PPI) process. The programme is being mimicked by other cities and government agencies, but so …

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 …

Remote maintenance activities in ITER will be performed by a unique set of hardware systems, supported by an extensive software kit. A layer of middleware will manage and control a complex set of interconnections between teams of operators, hardware devices in various operating theatres, and databases …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

IT organizations and CEO‟s are, and should be, concerned these days about the (lack of) data confidentiality and the usage of „shadow‟ IT systems by employees. Not only does the company risk monetary loss or public embarrassment, the senior management might also risk personal fines or even imprisonment. …
