Dual-beam heterodyne Fourier domain optical coherence tomography

Theo Lasser, Rainer Leitgeb, Adrian Bachmann, Roland Michaely

We report on a novel method combining achromatic complex FDOCT signal reconstruction with a common path and dual beam configuration. The complex signal reconstruction allows resolving the complex ambiguity of the Fourier transform and to enhance the achiev ...

Thermal decomposition of AlH3 studied by in situ synchrotron X-ray diffraction and thermal desorption spectroscopy

Philip Pattison

The thermal decomposition of alane was investigated by application of synchrotron X-ray diffraction (SR-XRD) and thermal desorption spectroscopy (TDS). Two polymorphs were studied, α- and γ-AlH3. Activation energies, anisotropic volume expansions, and phas ...

Spatial feltering in sensor networks with computation codes

Michael Christoph Gastpar

A data collection problem in sensor networks is formulated in which the number of channel uses per source sample is greater than one. An example of this problem is given in which the objective of the data collector is to compute a filtered and downsampled ...

Efflorescence transitions of ammonium sulfate particles coated with secondary organic aerosol

Satoshi Takahama, Spyros Pandis

Ammonium sulfate particles were generated by atomization and introduced into a smog chamber where they were coated with secondary organic aerosol from ozonolysis of limonene or alpha-pinene. These mixed particles were then sampled with a humidified Tandem- ...

Implications of NbTi short-sample test results and analysis for the ITER poloidal field conductor insert (PFCI)

Pierluigi Bruzzone, Marina Ricci

As the test of the PFC1 is foreseen in 2006 at JAERI Naka, Japan, it is essential to consider in detail the lessons learned from the short NbTi sample tests, as well as the issues left open after them, in order to develop a suitable test program of the PFC ...

Using an Artificial Intelligence Tool to Perform Science Data Downlink Planning as Part of the Mission Planning Activities of Mars Express

Thomas Léauté

Solving the science data downlink problem for Mars Express (MEX) has been a challenge. An artificial intelligence (AI) based tool, MEXAR2, has been developed and integrated in the mission planning process that allows the user to quickly and effortlessly ge ...

A low cost joint for the ITER PF coils, design and test results

Pierluigi Bruzzone, Boris Stepanov, Martin Vogel

The Poloidal Field (PF) coils of the International Thermonuclear Experimental Reactor (ITER) are designed using of NbTi cable-in-conduit conductors carrying a current up to 45 kA. Each PF coil consists of several modules Wound in double pancakes. Joints co ...

Numerical Simulation of Two-Phase Partition Chromatography in Microchannels for Moderated Log P Measurements

Hubert Girault, Pierre-Alain Carrupt

A finite element simulation has been used in order to study the partition chromatography process of one species between an aqueous mobile phase and an organic stationary phase located at the bottom of a rectangular microchannel. The transient model incorpo ...

Rate-Distortion Problem for Physics Based Distributed Sensing

Martin Vetterli, Robert Konsbruck

We consider the rate-distortion problem for sensing the continuous space-time physical temperature in a circular ring on which a heat source is applied over space and time, and which is allowed to cool by radiation or convection. The heat source is modelle ...
