table grapes (vitis vinifera l. cv. shahroodi) were stored for 45 days under modified atmospher packaging (map) with four gas combination treatments including gc1 (control or air), gc2 (10%co2+5%o2), gc3 (10%co2+15%o2) and gc4 (10%co2 + 60%o2) using two types of polymeric films pp (polypropylene) and pe (polyethylene) at 1oc and 80-90% rh. measurements were carried out after each 15 days at 1oc...

Let G be a compact Lie group, and let LG denote the corresponding loop group. Let (X,ω) be a weakly symplectic Banach manifold. Consider a Hamiltonian action of LG on (X,ω), and assume that the moment map μ : X −→ Lg∗ is proper. We consider the function |μ|2 : X −→ R, and use a version of Morse theory to show that the inclusion map j : μ(0) −→ X induces a surjection j∗ : H∗ G(X) −→ H∗ G(μ−1(0))...

A 3-D invertible map generating a 4-loop solenoid attractor is presented. The attractor of the "standard" 4-solenoid turns out to be "fat" that is, fractal dimensionality exceeds topological dimensionality by more than unity. If a fourth variable that is weakly damped is added to this 3-variable map, a new type of attractor is generated. In a cross section it is a continuous nowheredifTerentiab...

A smooth map f: M ! N between semi-riemannian manifolds is called a harmonic morphism if f pulls back harmonic functions (i.e., local solutions of the Laplace{Beltrami equation) on N into harmonic functions on M. It is shown that a harmonic morphism is the same as a harmonic map which is moreover horizontally weakly conformal, these two notions being likewise carried over from the riemannian ca...

This paper examines the opportunity of Kohonen's feature map adaptation for selection of useful features in the task of clusterization of multidimensional data. Based on the biological prototype of the self-organizing map, the modified Kohonen’s map was built in the way to be able to select useful features in the task of clusterization. The neuron map based on the new training algorithm has sho...

Chaotic tent map has robust chaos for control parameter μ = 2. Perturbation of control parameter v...

We exhibit a two-dimensional, acyclic, Eilenberg–Mac Lane space W such that, for every space X, the plus-construction X+ with respect to the largest perfect subgroup of π1(X) coincides, up to homotopy, with the W -nullification of X; that is, the natural map X → X+ is homotopy initial among maps X → Y where the based mapping space map∗(W,Y ) is weakly contractible. Furthermore, we describe the ...

We consider the Banach-Mackey property for pairs of vector spaces E and E′ which are in duality. Let A be an algebra of sets and assume that P is an additive map from A into the projection operators on E. We define a continuous gliding hump property for the map P and show that pairs with this gliding hump property and another measure theoretic property are Banach-Mackey pairs,i.e., weakly bound...

In this paper the existence of the contingent epiderivative of a set-valued map is studied from a variational perspective. We give a variational characterization of the ideal minimal of a weakly compact set. As a consequence we characterize the existence of the contingent epiderivative in terms of an associated family of variational systems. When a set-valued map takes values in Rn we show that...
