Abstract: A copper electroplating solution comprising a copper salt, a source of halide ions, and a linear or branched polyhydroxyl. The copper electroplating solution is used to deposit copper having a high density of nanotwinned columnar copper grains on a substrate. The linear or branched polyhydroxyl may comprise a reaction product between 2,3-epoxy-1-propanol and aminic alcohol or ammonium alcohol.

Abstract: An apparatus for measuring a spatially under-sampled Bidirectional Reflectance Distribution Function (BRDF) of a surface. The apparatus may comprise a first light source directed to illuminate the surface from a first illumination direction, and a plurality of sensors positioned to receive light reflected by the surface. The plurality of sensors may comprise first, second and third sensors positioned to receive light reflected by the surface in first, second and third non-coplanar directions. In various embodiments, the apparatus may also comprise a computer in communication with the plurality of sensors. The computer is configured to convert light sensed by the plurality of sensors into a first appearance property of the surface considering the first, second, and third reflectance directions. A method of calculating xDNA, the vector sum of the observed reflectance intensity over a plurality of wavelengths and angles. Methods of using the calculated xDNA for formulating recipes for a surfaces colors.

Abstract: Computer-implemented systems and methods for processing image data of a process-free plate are provided according to the present disclosure. The systems and methods may, generally, include a data acquisition step/means for receiving image data using one or more channels of a imaging system, each channel functioning to image the same target region of a process-free plate using a different wavelength of light, and a data processing step/means for filtering the image data using at least one of: (i) self-filtering, (ii) Fourier shrinkage and (iii) Wavelet shrinkage. When the image data is received using a plurality of channels, the received image data may advantageously be combined so as to optimize contrast-to-noise performance. The disclosed systems and methods may advantageously perform the operations of image de-noising, contrast enhancement, and thresholding, and may further involve compensation techniques, e.g., for minimizing distortion and blurring effects.

Abstract: A controller for apportioning high amplitude and low amplitude control signals between two aircraft control surfaces, such as for example, between an elevator and an associated movable horizontal stabilizer. The signals are separated along a first path and a second path. Signals along the first path are fed to a low pass filter where the low frequency signals are separated and an elevator position error signal is generated. Those signals exceeding a predetermined elevator position error are fed in the form of stabilizer rate signals to a stabilizer position module where a stabilizer positioning signal is generated and then fed to a stabilizer servo system to reposition the horizontal stabilizer. The stabilizer positioning signal is also fed to a multiplier where it is multiplied by a predetermined pitch effectiveness ratio representing the amount of elevator deflection required to achieve the same pitch moment as one degree of stabilizer deflection.
