The relationship and possible interplay between different knowledge representation and reasoning paradigms is a fundamental topic in artificial intelligence. For expressive knowledge representation for the Semantic Web, two different paradigms – namely Description Logics (DLs) and Logic Programming – are the two most successful approaches. A study of their exact relationships is thus paramount....

Digital light processing (DLP) is an accurate additive manufacturing (AM) technology suitable for producing micro-parts by photopolymerization. As most AM technologies, anisotropy of parts made by DLP is a key issue to deal with, taking into account that several operational factors modify this characteristic. Design for this technology and photopolymers becomes a challenge because the manufactu...

In this paper, we discuss solving the DLP over GF (36·97) by using the function field sieve (FFS) for breaking paring-based cryptosystems using the ηT pairing over GF (3 ). The extension degree 97 has been intensively used in benchmarking tests for the implementation of the ηT pairing, and the order (923-bit) of GF (3 6·97) is substantially larger than the previous world record (676-bit) of sol...

DLP (Digital Light Processing) is about to invade stereo applications, one of the last bastions of CRT projection technology. This paper presents various methods for achieving stereo and their application to DLP projectors. The newly developed sequential stereo capable projectors are also introduced and their performance characteris tics discussed along with artifacts. Also presented are ways t...

This paper presents a new simple scheme for theft-protected proprietary certificate problem by introducing a mobile phone as an additional requirement for the proprietor and this scheme is analyzed to be more secured than the one presented by M. Jakobsson, et al. Secondly we present the proprietary certification process using Elliptic Curve Discrete Log Problem (ECDLP) instead of Discrete Log P...

Drosophila melanogaster follicle stem cells are controlled by Wingless (Wg) ligands secreted 50 µm away, raising the question of how long-distance Wg spreading occurs. In this issue of JCB, Wang and Page-McCaw (2014. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201403084) demonstrate a potential mechanism by which the heparan sulfate proteoglycan Dally-like (Dlp) promotes Wg travel, whereas matr...

Since VACOR was first introduced to the market as a fast acting rodenticide in 1975, it has been sold successfully throughout the United States. The VACOR line is sold over-the-counter as a ready-to-use bait for rats and mice. The DLP-787 rodenticide line was introduced to the market for sale to professional users only. This line includes both bait and mouse tracking products. It has been well ...

Three defensin-like peptides (DLPs) were isolated from platypus venom and sequenced. One of these peptides, DLP-1, was synthesized chemically and its three-dimensional structure was determined using NMR spectroscopy. The main structural elements of this 42-residue peptide were an anti-parallel beta-sheet comprising residues 15-18 and 37-40 and a small 3(10) helix spanning residues 10-12. The ov...

This document is an evaluation of the discrete logarithm problem over finite fields (DLP), as a basis for designing cryptographic schemes. It relies on the analysis of numerous research papers on the subject. The present report is organized as follows: firstly, we review the DLP and several related problems such as the Diffie-Hellman problem. Next, we analyze the various algorithms that are cur...

This paper proposes a new signature scheme based on two hard problems : the cube root extraction modulo a composite moduli (which is equivalent to the factorisation of the moduli, IFP) and the discrete logarithm problem(DLP). By combining these two cryptographic assumptions, we introduce an efficient and strongly secure signature scheme. We show that if an adversary can break the new scheme wit...
