This paper describes the design of a modified tent map characterized by a uniform probability density function. The use of this map is proposed as an alternative to the tent map and the Bernoulli shift. It is shown that practical circuits implementing the latter two maps may possess parasitic stable equilibria, fact which would prevent the desired chaotic behavior of the system. On the other ha...

The article reveals the problem of making a decision on design corporate uniform in context contradictory requirements for uniformity clothing employees and needs participants dress code self-expression. combination above factors creates specificity assessment projects, since it becomes necessary to predict stability policy, acceptance its by all interested parties. To solve this problem, metho...

We study the maximum a posteriori (MAP) decoding of memoryless non-uniform sources over multiple-antenna channels. Our model is general enough to include spacetime coding, BLAST architectures, and single-transmit multi-receive antenna systems which employ maximal receive combining (MRC) and any kind of channel coding. We derive a closed-form single-letter expression for the codeword pairwise er...

We construct the uniform infinite planar map (UIPM), obtained as the n → ∞ local limit of planar maps with n edges, chosen uniformly at random. We then describe how the UIPM can be sampled using a “peeling” process, in a similar way as for uniform triangulations. This process allows us to prove that for bond and site percolation on the UIPM, the percolation thresholds are p c = 1/2 and p site c...

In this paper we propose an extension of grayscale histogram equalization for color images. For aesthetic reasons, previously proposed color histogram equalization techniques do not generate uniform color histograms. Our method will always generate an almost uniform color histogram thus making an optimal use of the color space. This is particularly interesting for pseudo-color scientific visual...

We study the question of whether or not contractive representations of logmodular algebras are completely contractive. We prove that a 2-contractive representation of a logmodular algebra extends to a positive map on the enveloping C∗-algebra, which we show generalizes a result of Foias and Suciu on uniform logmodular algebras. Our proof uses non-commutative operator space generalizations of cl...

Recently, Lima and Randrianarivony pointed out the role of the property (β) of Rolewicz in nonlinear quotient problems, and answered a ten-year-old question of Bates, Johnson, Lindenstrauss, Preiss and Schechtman. In the present paper, we prove that the modulus of asymptotic uniform smoothness of the range space of a uniform quotient map can be compared with the modulus of (β) of the domain spa...

A b stra c t. Here for a smooth bounded Euclidean domain-and a smooth Riemannian manifold N , we show that almost every smooth map ' : @-! N serves as boundary data for at most one energy minimizing map u :-! N [Theorem 5. 2]. We also obtain some uniform boundary regularity estimates for energy minimizers [Theorem 2. 1 ], which n ot only are important to our proof, but also imply some other pro...
