Optimistic execution techniques are widely used in the field of parallel discrete event simulation. In this paper we show that optimistic execution can also be used to parallelize program control structures. We discuss the requirements for handling unbounded constructs and demonstrate the need for a flexible time– stamp allocation scheme. We present a scheme using variable–length time–stamps wh...

This paper brings attention to the effects of PRWORA on householdlevel Food Stamps recipiency, Food Stamps allotments, and food security among children of immigrants using the Survey of Program Dynamics. This paper further seeks to examine the affect of cutbacks on welfare allotments on “mixed status” families and whether any such changes in Food Stamps receipt and allotments led to higher leve...

This paper presents a segmentation algorithm based on feature selection in wavelet space. The aim is to automatically separate in postal envelopes the regions related to background, stamps, rubber stamps, and the address blocks. First, a typical image of a postal envelope is decomposed using Mallat algorithm and Haar basis. High frequency channel outputs are analyzed to locate salient points in...
