Specific Isochoric Heat Capacity Measurements for Liquid Isobutane

January 1, 2003
Author(s)
Hiroyuki Miyamoto, Hiroshi Kitajima, Noboru Kagawa, Joe W. Magee, Seizo Tsuruno, Koichi Watanabe
Experimental specific isochoric heat capacities (C v) and PρT properties for isobutane are presented that were measured with a twin-cell type adiabatic isochoric calorimeter. The measurements were obtained for temperatures from 272 to 408 K and for

A Hybrid CPU-GPU Approach to Fourier-Based Image Stitching of Optical Microscopy Images

March 3, 2013
Author(s)
Walid Keyrouz, Timothy J. Blattner, Bertrand C. Stivalet, Joe Chalfoun, Mary C. Brady, Shujia Zhou
We present a hybrid CPU-GPU approach for the Fourier-based stitching of optical microscopy images. This system achieves sub-minute stitching rates with large grids; it stitches a grid of 59x42 tiles in 26 seconds on a two-CPU (8 physical cores) & two-GPU
