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) …

Resonance-enhanced laser-induced breakdown spectroscopy was used to increase the elemental sensitivity of laser-induced breakdown spectroscopy. In resonance-enhanced laser-induced breakdown spectroscopy, two lasers are used. The first laser creates a plasma, and the second laser re excites the most …

Fuel cell hybrid power trains comprise an energy storage to supply peaks in the power demand and to facilitate regenerative braking. In terms of control systems, the presence of storage provides additional freedom to minimize the vehicle’s fuel consumption. In a previous paper [1] an analytical solution …

Nuclear fusion is seen as one of the future technologies for roducing electrical power. In a hot and con ned plasma deuterium and tritium will melt together and form a helium nucleus and a neutron. This process produces a total of 17.6 MeV energy. In the plasma instabilities occur. Suppression of these …

The recently developed HyperCollar applicator was specifically designed to heat tumors in the head and neck region. The applicator uses twelve antennas to create an EM interference pattern, which applies heat to the target area. Patients' position and movement needs to be tightly monitored and controlled …

Het realiseren van verbeteringen in Europese netwerken vereist een sterke mate van samenwerking. Logistieke bedrijven zijn bij de ontwikkeling van deze nieuwe netwerken doorgaans sterk gefocused op harde feiten zoals optimalisatieberekeningen en kostenvoordelen terwijl aandacht voor partnerselectie en …

Setting up strategic alliances and trying to attain the intended goals is a highrisk venture. Most research into this topic is confined to already established alliances. This research will focus on perceived performance risks by organizations considering a possible strategic venture. Following other …

A wheelchair undergoes vibrations while traveling over obstacles and uneven surfaces, resulting in whole body vibration of the person sitting in the wheelchair. According to clinicians, people with spinal cord injury (SCI) report that vibration evokes spasticity. The relatively …

In this study, the impact of a training program focusing on the deliberate use of interventions during coaching dialogues with prospective teachers was investigated. Video recordings were analyzed of coaching dialogues carried on in the workplace by 28 teachers in primary education with the prospective …
