Description and texts for the auxiliary programs for processing video information on the YeS computer. Part 3: Test program 2
The functions were discribed and the operating instructions, the block diagram and the proposed versions are given for modifying the program in order to obtain the statistical characteristics of multi-channel video information. The program implements certain man-machine methods for investigating video information. It permits representation of the material and its statistical characteristics in a form which is convenient for the user
Critical behavior of 3D Z(N) lattice gauge theories at zero temperature
Three-dimensional lattice gauge theories at zero temperature are
studied for various values of . Using a modified phenomenological
renormalization group, we explore the critical behavior of the generalized
model for . Numerical computations are used to simulate
vector models for for lattices with linear extension up
to . We locate the critical points of phase transitions and establish
their scaling with . The values of the critical indices indicate that the
models with belong to the universality class of the three-dimensional
model. However, the exponent derived from the heat capacity is
consistent with the Ising universality class. We discuss a possible resolution
of this puzzle. We also demonstrate the existence of a rotationally symmetric
region within the ordered phase for all at least in the finite
volume.Comment: 25 pages, 4 figures, 8 table
Međusobni odnos strukture materijala i mehaničkih svojstava niskolegiranih molibdenovih slitina
As a result of joint analysis of experimental data on the structure and mechanical properties of low-alloy molybdenum alloys of the systems Mo-Al-B, Mo-Zr-B, Mo-Zr-Hf-B and Mo-Re we have established that for considered class of materials over the wide range of temperature there exist close correlations between the structural state, short-term, and low-cycle and high-cycle fatigue strength characteristic.Kao rezultat zajedničke analize eksperimentalnih podataka za strukturu i mehanička svojstva niskolegiranih molibdenih slitina sustava Mo-Al-B, Mo-Zr-B, Mo-Zr-Hf-B i Mo-Re ustanovljeno je da za razmatranu klasu materijala u širokom rasponu temperature postoji uska korelacija između svojstava strukture, kratkoročne čvrstoće, te čvrstoće na niskociklični i visokociklični zamor
THE INCREASING THE DURATION OF FUNCTIONAL BEVERAGES METHODS
In the Russia beverage market, functional beverages are increasingly popular with the population due to their intensive lifestyle and worsening environmental situation. Of great importance is the shelf life of drinks, since they determine the presence in the composition of useful nutrients that affect the various systems of functioning of the human body. The main groups of functional compounds are given. Ways to increase the shelf life of beverages, all aspects and their impact on the safety of the functional components of beverages are considered. The role of flavonoids as one of the groups of functional compounds has been evaluated. Recent studies on the effect of certain functional compounds on each other are given.In the Russia beverage market, functional beverages are increasingly popular with the population due to their intensive lifestyle and worsening environmental situation.

Phase transitions in strongly coupled 3d Z(N) lattice gauge theories at finite temperature
We perform an analytical and numerical study of the phase transitions in
three-dimensional Z(N) lattice gauge theories at finite temperature for N>4
exploiting equivalence of these models with a generalized version of the
two-dimensional vector Potts models in the limit of vanishing spatial coupling.
In this limit the Polyakov loops play the role of Z(N) spins. The effective
couplings of these two-dimensional spin models are calculated explicitly. It is
argued that the effective spin models have two phase transitions of BKT type.
This is confirmed by large-scale Monte Carlo simulations. Using a cluster
algorithm we locate the position of the critical points and study the critical
behavior across both phase transitions in details. In particular, we determine
various critical indices, compute the helicity modulus, the average action and
the specific heat. A scaling formula for the critical points with N is
proposed.Comment: 28 pages, 12 figures, 12 tables; version to appear on Phys. Rev.
