The cyclic segmented parallel prefix (CSPP) circuit is a varation on parallel prefix. Whereas ordinary parallel prefix computes prefix sums of a vector from the beginning, CSPP allows the starting point to move arbitrarily, with the data “wrapping around.” The wraparound is widely useful. We have used CSPP to redesign many components of a superscalar processor to run in time logarithmic in the ...

This paper analyzes price collusion in a repeated game with two submarkets: standard and premium quality segment. Within this setting, we study four types of price-fixing agreement: (i) segment-wide cartel the submarket only, (ii) (iii) cartels, (iv) an industry-wide cartel. We present complete characterization collusive pricing equilibrium examine corresponding effect on market shares welfare....

Background: Accurate brain tissue segmentation from magnetic resonance (MR) images is an important step in analysis of cerebral images. There are software packages which are used for brain segmentation. These packages usually contain a set of skull stripping, intensity non-uniformity (bias) correction and segmentation routines. Thus, assessment of the quality of the segmented gray matter (GM), ...
