Box representations of embedded graphs

A d-box is the cartesian product of d intervals of R and a d-box representation of a graph G is a representation of G as the intersection graph of a set of d-boxes in R. It was proved by Thomassen in 1986 that every planar graph has a 3-box representation. In this paper we prove that every graph embedded in a fixed orientable surface, without short non-contractible cycles, has a 5-box represent...

Provably Secure Double-Block-Length Hash Functions in a Black-Box Model

In CRYPTO’89, Merkle presented three double-block-length hash functions based on DES. They are optimally collision resistant in a black-box model, that is, the time complexity of any collision-finding algorithm for them is Ω(2 ) if DES is a random block cipher, where is the output length. Their drawback is that their rates are low. In this article, new double-block-length hash functions with hi...

effect of oral presentation on development of l2 learners grammar

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...

Embedded Emulator SPEED-BOX MB2100-01-E

In recent years, an increasing number of waterfall-type V-shaped processes have been adopted in sites of embedded system development where programs are growing in scale and becoming more complex (Figure 1). In V-shaped processes, verification (called conformance testing) using the actual device is an important process, as is the extraction of requirements, designing, and building. The demand fo...
