We investigate the thermodynamic and dynamic properties of a three dimensional associating lattice gas (ALG) model through Monte Carlo simulations. The ALG model combines a soft core potential and orientational degrees of freedom. The competition of directional attractive forces and the soft core potential results in two coexisting liquid phases which are also connected through order-disorder c...

This is a copy of the talk given at the conference “Methods in Field Theory” at Stará Lesná, The Slovak Republic. Sepemeber 22-26, 1997. An introduction to the noncommutative sphere and a summary of the results of articles q-alg/9703038 [1], and q-alg/9708003 [2] is given. This includes results about the the algebra of scalar, spinor and vector fields on the noncommutative sphere. Possible exte...

Bu çal??mada, okul öncesi dönemde çocuklar?n beden alg?s? üzerinde etkili faktörler, bu faktörlerin çocuklara etkileri ve alg?s?n?n belirlenmesine ili?kin ara?t?rma yöntem ölçme araçlar? hakk?nda literatür incelenmi?tir. Ki?inin bedeni sahip oldu?u olumlu ya da olumsuz de?erlendirmelerin tümü, onun alg?s?n? olu?turur. Bireylerde memnuniyetsizli?inin genellikle ergenlikte ba?lad??? dü?ünülse de ...

We extend Barr’s well-known characterization of the final coalgebra of a Set-endofunctor H as the completion of its initial algebra to the EilenbergMoore category Alg(M) of algebras associated to a Set-monad M, if H can be lifted to Alg(M). As further analysis, we introduce the notion of commuting pair of endofunctors (T,H) with respect to a monad M and show that under reasonable assumptions, t...

Matsui’s one-dimensional Alg. 2 can be used for recovering bits of the last round key of a block cipher. In this paper a truly multidimensional extension of Alg. 2 based on established statistical theory is presented. Two possible methods, an optimal method based on the log-likelihood ratio and a χ2-based goodness-of-fit test are compared in theory and by practical experiments on reduced round ...

Let Pn = K[x1, . . . , xn] be a polynomial algebra over a field K of characteristic zero and div0n (respectively, div c n) be the Lie algebra of derivations of Pn with zero (respectively, constant) divergence. We prove that AutLie(div 0 n) ≃ AutK−alg(Pn) (n ≥ 2) and AutLie(div c n) ≃ AutK−alg(Pn). The Lie algebra div c n is a maximal Lie subalgebra of DerK(Pn). Minimal finite sets of generators...

We present a denotational semantics for an Algol-like language Alg which is fully abstract for the second order subset of Alg. This constitutes the rst signiicant full abstraction result for a block structured language with local variables. In this preliminary report we concentrate on the construction of the denotational model and on the main ideas of the full abstraction proof. For more backgr...
