Improving the Quark Number Susceptibilities for Staggered Fermions [PDF]
, 2002 Quark number susceptibilities approach their ideal gas limit at sufficiently high temperatures. As in the case of other thermodynamic quantities, this limit itself is altered substantially on lattices with small temporal extent, N_t = 4-8, making it thus

Evaluating performance of image segmentation criteria and techniques
EURO Journal on Computational Optimization, 2013 The image segmentation problem is to delineate, or segment, a salient feature in an image. As such, this is a bipartition problem with the goal of separating the foreground from the background. An NP-hard optimization problem, the Normalized Cut problem,

PERSPECTIVES IN ELECTRONIC SHOPPING: ON BEYOND AUTOMATED ORDER ENTRY [PDF]
, 1989 Large-scale electronic shopping systems need to accommodate both (a) a large number of products, many of which are close substitutes, and (b) a heterogeneous body of customers who have complex, multidimensional and perhaps rapidly changing-preferences ...
