Publication number: 20100076941Abstract: A system and method for performing a scan of an input sequence in a parallel processor having a shared register file. A two dimensional matrix is generated, having a number of rows representing a number of threads and a number of columns based on the input sequence block size and the number of rows. One or more padding columns may be added to the matrix to avoid or reduce memory bank conflicts. A first traversal of the rows performs a reduction or a scan of each of the rows in parallel, storing the reduction values. The reduction values are used during a second traversal to propagate the reduction values. In a segmented scan, propagation is selectively performed based on flags representing segment boundaries.Type: ApplicationFiled: September 9, 2008Publication date: March 25, 2010Applicant: Microsoft CorporationInventors: Yuri Dotsenko, Naga Govindaraju, Charles Boyd, John Manferdelli, Peter-Pike Sloan

Patent number: 7454293Abstract: A method for enhanced detection and statistical analysis of differentially expressed genes in gene chip microarrays employs: (a) transformation of gene expression data into an expression data matrix (image data paradigm); (b) wavelet denoising of expression data matrix values to enhance their signal-to-noise ratio; and (c) singular value decomposition (SVD) of the wavelet-denoised expression data matrix to concentrate most of the gene expression signal in primary matrix eigenarrays to enhance the separation of true gene expression values from background noise. The transformation of gene chip data into an image data paradigm facilitates the use of powerful image data processing techniques, including a generalized logarithm (g-log) function to stabilize variance over intensity, and the WSVD combination of wavelet packet transform and denoising and SVD to clearly enhance separation of the truly changed genes from background noise.Type: GrantFiled: January 7, 2005Date of Patent: November 18, 2008Assignee: University of Hawai'iInventors: Gordon S.

Publication number: 20080001105Abstract: An apparatus utilizes optical reflectivity (REF) to measure concentrations in liquids. The REF optical system is packaged in a compact and cost-effective form factor. An electronic circuit drives the optical system. The miniaturized REF sensor is situated in an optical-fluidic cell or an optical-fluidic manifold with an optical window in contact with the liquid. Changes in a total internal reflection (TIR) signal are sensitive to temperature and concentration of the liquid. These changes in the TIR signal are used to accurately determine the concentration in the liquid. The liquids may be either static or dynamic.Type: ApplicationFiled: September 10, 2007Publication date: January 3, 2008Applicant: JETALON SOLUTIONS, INC.Inventors: Ronald Chiarello, Charles Boyd, Duncan McPhee

Publication number: 20060125823Abstract: An API is provided to feed multiple data objects, wherever originated or located at the time of operation, to a 3D graphics chip simultaneously or in parallel. Multiple containers may be fed to a 3D graphics chip memory at the same time. In the case where data is being transmitted to a graphics chip memory, wherein the data includes the same spatial position of pixel(s), but only the orientation or color is changing, the data may be loaded into two separate containers, with a header description understood by the graphics chip and implemented by the graphics API, whereby a single copy of the position data can be loaded into one container, and the changing color or orientation data may be loaded into a second container. Thus, when received by the graphics chip, the data is loaded correctly into register space and processed according to the header description.Type: ApplicationFiled: February 3, 2006Publication date: June 15, 2006Applicant: Microsoft CorporationInventors: Charles Boyd, Michael Toelle
