According to slowly serial processing speed in the photorealistic rendering technology, the paper proposes many lights processing. Using parallel strategy of load balancing and optimizing calculation mode, ambient light 、 diffuse light and specular light are added when they are calculated separately. Different number of PE (processing unit) with different schemes is to improve the processing sp...

The theoretical equivalence between the DLP and DHP problems was shown by Maurer in 1994. His work was then reexamined by Muzereau et al. [11] for the special case of elliptic curves used in practical cryptographic applications. This paper improves on the latter and tries to get the tightest possible reduction in terms of computational equivalence, using Maurer’s method.

Pairing based cryptography is in a dangerous position following the breakthroughs on discrete logarithms computations in finite fields of small characteristic. Remaining instances are built over finite fields of large characteristic and their security relies on the fact the embedding field of the underlying curve is relatively large. How large is debatable. The aim of our work is to sustain the...

We consider a network revenue management problem with customer choice and exogenous prices. We study the performance of a class of certainty equivalent heuristic control policies. These heuristics periodically re-solve the deterministic Linear Program (DLP) that results when all future random variables are replaced by their average values and implement the solutions in a probabilistic manner. W...

Gaudry has described a new algorithm (Gaudry’s variant) for the discrete logarithm problem (DLP) in hyperelliptic curves. For a hyperelliptic curve of a small genus on a finite field GF(q), Gaudry’s variant solves for the DLP in time O(q2+2). This paper shows that Cab curves can be attacked with a modified form of Gaudry’s variant and presents the timing results of such attack. However, Gaudry’...

In this paper we show how some recent ideas regarding the discrete logarithm problem (DLP) in finite fields of small characteristic may be applied to compute logarithms in some very large fields extremely efficiently. In particular, we demonstrate a practical DLP break in the finite field of 2 elements, using just a single core-month.

This paper explores the creation of autostereocopic images using a light field with a focus on real-time generation of these images using the GPU.

introduction: radiation imaging is one of the applicable methods in diagnostic medicine and nondestructive testing for industrial applications. in nondestructive 3d imaging, in addition to the radiation source, there is a requirement for a suitable detection system, data acquisition system, mechanical sections for moving objects, reconstruction algorithm and finally a computer for processing an...
