Abstract: A Fourier transform spectrometer (FTS) data acquisition system includes an FTS spectrometer that receives a spectral signal and a laser signal. The system further includes a wideband detector, which is in communication with the FTS spectrometer and receives the spectral signal and laser signal from the FTS spectrometer. The wideband detector produces a composite signal comprising the laser signal and the spectral signal. The system further comprises a converter in communication with the wideband detector to receive and digitize the composite signal. The system further includes a signal processing unit that receives the composite signal from the converter. The signal processing unit further filters the laser signal and the spectral signal from the composite signal and demodulates the laser signal, to produce velocity corrected spectral data.

Abstract: Disclosed herein are systems, computer-implemented methods, and tangible computer-readable media for coordinating communications between a ground station, a control center, and a spacecraft. The method receives a call to a simple, unified application programmer interface implementing communications protocols related to outer space, when instruction relates to receiving a command at the control center for the ground station generate an abstract message by agreeing upon a format for each type of abstract message with the ground station and using a set of message definitions to configure the command in the agreed upon format, encode the abstract message to generate an encoded message, and transfer the encoded message to the ground station, and perform similar actions when the instruction relates to receiving a second command as a second encoded message at the ground station from the control center and when the determined instruction type relates to transmitting information to the control center.

Abstract: Actuator assemblies are formed by at least one cylinder where each cylinder is formed by at least one piezoelectric fiber composite actuator adapted to have actuation energy applied thereto.

Abstract: Systems, methods and apparatus are provided through which in some embodiments of recursive hierarchical segmentation of data with any number of spatial dimensions. Some embodiments of the recursive hierarchical segmentation include computationally efficient parallel implementations and other embodiments of the recursive hierarchical segmentation include computationally efficient serial implementations.

Abstract: A method is provided for the controlled deposition and alignment of carbon nanotubes. A carbon nanotube (CNT) attraction material is deposited on a substrate in the gap region between two electrodes on the substrate. An electric potential is applied to the two electrodes. The CNT attraction material is wetted with a solution defined by a carrier liquid having carbon nanotubes (CNTs) suspended therein. A portion of the CNTs align with the electric field and adhere to the CNT attraction material. The carrier liquid and any CNTs not adhered to the CNT attraction material are then removed.

Abstract: A composite thermal barrier coating for a substrate has a first layer including a first ceramic material and a second layer including a second ceramic material impregnated with a glass, the glass being a ternary eutectic. The glass may consist of about 14.6 weight percent Al.sub.2 O.sub.3, about 23.3 weight percent CaO, and about 62.1 weight percent SiO.sub.2. The first and second ceramic materials may include yttria-stabilized zirconia.
