Overcoming Shadows in 3-Source Photometric Stereo
—Light occlusions are one of the most significant difficulties of photometric stereo methods. When three or more images are available without occlusion, the local surface orien...

Removal of Partial Occlusion from Single Images
— This paper examines large partial occlusions in an image, which occur near depth discontinuities when the foreground object is severely out of focus. We model these partial occ...

Performance modeling of HS-RR-TCP over load-balanced optical burst-switched (OBS) networks
TCP-over-OBS is a promising transport paradigm to support next-generation Internet. It is well-known that loadbalanced routing generally improves loss performance over OBS. We ide...

A distributed impairment aware QoS framework for all-optical networks
—Different physical impairments can occur in optical transmission systems. Impairments such as fiber nonlinear effects are dependent on network state and vary with traffic and to...

The split closure of a strictly convex body
The Chv´atal-Gomory closure and the split closure of a rational polyhedron are rational polyhedra. It was recently shown that the Chv´atal-Gomory closure of a strictly convex bo...

Stock repurchase with an adaptive reservation price: A study of the greedy policy
We consider the problem of stock repurchase over a finite time horizon. We assume that a firm has a reservation price for the stock, which is the highest price that the firm is ...

Cancellation in Skew Lattices
Distributive lattices are well known to be precisely those lattices that possess cancellation: x ∨ y = x ∨ z and x ∧ y = x ∧ z imply y = z. Cancellation, in turn, occurs wh...
