Although the idea must have been around for years the use of a ball for the calibration of interferometer transmissions spheres was, to our knowledge first reported in 1999. The ball used at the time was made of black (neutral density filter) glass and worked fine for a demonstration of the principle but was not really practical because of its relative softness of the glass and susceptibility t...

This paper describes a method of interactively visualizing and directing the process of translating a sentence. The method allows a user to explore a model of syntax-based statistical machine translation (MT), to understand the model’s strengths and weaknesses, and to compare it to other MT systems. Using this visualization method, we can find and address conceptual and practical problems in an...

This paper presents an overview of NASA Langley’s research program in formal methods. The major goals of this work are to make formal methods practical for use on high integrity systems, to orchestrate the transfer of this technology to U.S. industry through use of carefully designed demonstration projects, and to exploit this technology to help achieve NASA’s goals in aeronautics. Several dire...

We present a phase locking scheme that enables the demonstration of a practical dual pump degenerate phase sensitive amplifier for 10 Gbit/s non-return to zero amplitude shift keying signals. The scheme makes use of cascaded Mach Zehnder modulators for creating the pump frequencies as well as of injection locking for extracting the signal carrier and synchronizing the local lasers. An in depth ...

This paper is concerned with the learning of robots behaviors in real environments. To face the constraints imposed by both physical and human spaces, it insists on the interest of a shaping process relying on learning by demonstrations. A mechanism for learning by demonstration is brie y described based on robot vision. The paper then discusses several general points related to learning by dem...

A polarization mode dispersion (PMD) measurement of a commercial telecommunication wavelength selective switch (WSS) using a quantum interferometric technique with polarization-entangled states is presented. Polarization-entangled photons with a broad spectral width covering the telecom band are produced using a chirped periodically poled nonlinear crystal. The first demonstration of a quantum ...

This paper presents the current status of the research in the Higgins project and provides background for a demonstration of the spoken dialogue system implemented within the project. The project represents the latest development in the ongoing dialogue systems research at KTH. The practical goal of the project is to build collaborative conversational dialogue systems in which research issues s...

southern hardwood flakes. Two major steps toward industrial practicability were accomplished with formulation of an economical fast-cure phenolic binder for both hardwood flakes and pine veneer', and laboratory demonstration that the panels could be hot. pressed in a one-step operation2. It has yet to be shown, however, that the one-etep technique practical for 20by 2O-inch panels will work on ...

The computation of surprise is one factor necessary for the computational detection of creativity in product design. An original computational model of surprise is proposed. A demonstration program was written to demonstrate the model’s validity. An experiment on human subjects was performed to test the program’s accuracy. The results of the experiment are analyzed, the model is assessed, and c...
