Detection of vegetation fluorescence gives information about plant functioning, stress and vitality. During the past decades several ground based laser fluorosensors have been developed to investigate these processes and to demonstrate the value of this technique. FLEX (= FLuorescense EXplorer) is a space mission to measure the fluorescence of...

The microbolometer spectrometer breadboard MIBS is a prism spectrometer that uses an uncooled microbolometer detector array and has been designed for the ESA EarthCARE mission. In order to demonstrate its feasibility a breadboard has been build, and tests have been performed that show good correlation between predicted and achieved results....

The advance in interactive/cooperative robotics and integration of robots into populated environments puts emphasis on robot-robot and robot-environment (incl. human) interactions. Sensing and sensory data interpretation play ever increasing role because sensing becomes the primary way of collecting information about the environment. In this...

This paper, which summarizes the conclusions of a WHO Expert meeting, is aimed at proposing indications to develop technical specifications for an accurate and affordable blood pressure measuring device for office/ clinic use in low resource settings. Blood pressure measuring devices to be used in low resource settings should be accurate,...

We present numerical computations of flow and heat transfer in multiple jets impinging normally on a flat heated surface, obtained with a new second-moment turbulence closure combined with an elliptic blending model of non-viscous wall blocking effect. This model provides the mean velocity and turbulent stress fields in very good agreement with...

This paper describes the model identification of control valve dynamics with a time delay. An experimental set-up is used to perform both frequency response and step response measurements on the control valve. An approximate realization algorithm and a new time delay estimation method are applied on the experimental data. The results illustrate...

Future space missions, among which the Darwin Space Interferometer, will consist of several free flying satellites. A complex metrology system is required to have all the components fly accurately in formation and have it operate as a single instrument. Our work focuses on a possible implementation of the sub-system that measures the absolute...

The effect of one-sided grazing mean flow on the acoustical impedance of rectangular orifices is measured at low Mach number and low Helmholtz number by means of a single microphone method. The results are fairly consistent with previous experimental results obtained by means of a two-microphone impedance tube. Furthermore no significant...

TNO TPD has an extensive experience in the realisation of highly stable passive and active opto-mechanical systems. Future missions of ESA like DARWIN [1] rely heavily on these systems such as metrology equipment, delay lines, nulling equipment etc.. The nulling equipment will be used in the Nulling mode of DARWIN in which it will detect Earth...

Optics lifetime and contamination is one of the major challenges for extreme ultraviolet (EUV) lithography. The basic contamination and lifetime limiting processes are carbon growth and oxidation of the mirrors. Without appropriate measures, optics lifetime will be limited to a few hours. Within the EUV α-tool project of ASML and Carl Zeiss,...

Due to lower mass, size and power demands and recognized increased reliability, microbolometer detectors seem to be well suited for small sattelite applications. Due to the improving technical performance, next generation instruments can use uncooled microbolometer arrays without significantly sacrificing performance. An example of this type of...
