Abstract:
A method of fabricating a porous metal-based biomaterial, the method includes dispersing microwave susceptors into organic solvent to form a homogeneous suspension, dispersing bioactive fillers into organic solvent to form a homogeneous solution, mixing metal powder with the homogeneous solution and the homogeneous suspension to form a mixture, cold-pressing the mixture into a compact with predefined shape and size, placing the compact in a sintering container, and emitting microwave to heat the compact and remove the organic solvent resided in the compact at the same time.
Abstract:
Improved techniques for acquiring symbol boundary timing at a receiver of a multicarrier data transmission system during a training sequence are disclosed. One aspect is symbol boundary determination at a receiver wherein minimal interference is used as a criterion in selecting from a plurality of potential symbol boundary timings. The symbol boundary determination at the receiver can be performed in a time domain or a frequency domain manner. Another aspect pertains to an improved training sequence wherein pairs of identical symbols are transmitted by a transmitter. These symbols can be supplied to the transmitter in a time domain or a frequency domain manner.

Abstract:
Improved techniques for concurrent channel equalization and far-end crosstalk channel compensation (e.g., estimation and/or cancellation) in a multicarrier data transmission system are disclosed. The improved techniques can produce coefficients for an electronic filter that provide channel equalization and for an electronic filter that provides cancellation of the far-end crosstalk. These coefficients can be initially trained and then subsequently updated during data transmission. Optionally, common coefficient determination resources can be utilized for both far-end crosstalk and near-end crosstalk purposes. These improved techniques are particularly suitable for use with a digital multicarrier communication system having multiple-input multiple-output systems.
Abstract:
A composition is provided that includes a plurality of calcined particles of terbium aluminum oxide having a mean particle domain size of between 30 and 600 nanometers. A translucent article having a surface includes polycrystalline terbium aluminum garnet having a mean grain size from 1 to 10 microns and light scattering inclusions of aluminum-rich oxide and/or terbium-rich oxide that are present at less than 2 surface area percent of the surface. A process for forming such an article involves sintering the above provided composition at a temperature between 1500° C. and 1700° C. to yield a sintered article. The article has improved translucency and even transparency as sintering is performed under vacuum at a temperature between 1610° C. and 1680° C. Hot isostatic pressing alone or in combination with article polishing also improves article translucency.
Abstract:
A method of modeling muscular tissue with active finite elements. The motion and stress-strain distribution of the muscular tissue can be predicted using interconnections of the active finite elements. Each active finite element includes a motor element and at least one passive element, such as a dashpot or spring.
Abstract:
A method of forming a field emission device and the resulting device including emitters formed of fiber segments. Tips are formed on the fiber segments that have a radius substantially small by exposing the tips to a reactive liquid for a duration of time The tips are coated with a low work function conducting material to form emitters.
