In this paper we introduce a practical flight coupon automatic processing system for scanning and recognition. We discuss the coupon classification, character location and binarization. And emphasize a high performance character segmentation and recognition engine, which are proved very effective. The results of experiment and commercial running applying the system are presented.

The Appalachian region has experienced persistently higher poverty and lower earnings than the rest of the United States. We examine whether lower skill differentials or differences in the returns to those skills lie at the root of the persistent Appalachian wage gap. Using Census data, we decompose the Appalachian wage gap using both mean and full distribution methods. Our findings suggest tha...

Spontaneous interaction in public places has evolved as crucial concern in interaction design, particularly in the domain of public advertising. Implicit interaction is a mode of spontaneous interaction in which the user is not attentively or explicitly expressing input to a system, but the system from observing the user, and considering all the available information that describes the user sit...

BACKGROUND HIV self-testing (HIVST) may play a role in addressing gaps in HIV testing coverage and as an entry point for HIV prevention services. We conducted a cluster randomized trial of 2 HIVST distribution mechanisms compared to the standard of care among female sex workers (FSWs) in Zambia. METHODS AND FINDINGS Trained peer educators in Kapiri Mposhi, Chirundu, and Livingstone, Zambia, e...

We analyze a variant of the coupon collector’s problem, in which the probabilities of obtaining coupons and the numbers of coupons in a collection may be non-uniform. We obtain a finite expression for the generating function of the probabilities to complete a collection and show how this generalizes several previous results about the coupon collector’s problem. Also, we provide applications abo...

The classic Coupon-Collector Problem (CCP) is generalized. Only basic probability theory is used. Centerpiece rather is an algorithm that efficiently counts all k-element transversals of a set system.
