The method of edge detection for X-ray medical images is proposed in the article. The method uses active contours approach for object edge refinement and combines advantages of active contours and those of the method proposed by author in his earlier researches. The method is suggested to be used in interactive diagnosis systems
The perspective construction of the combined machine for forest fires suppression is presented. The recommendations for its application at prevention of forest fires and their elimination are developed
The main statements of the methodology of
forecasting of social-economic phenomena and
processes in agriculture and the basic requirements to
ensure realistic results of forecasting the development
of the agrarian economy are considered in this work.
The relevance of this topic conditioned on the need of
developing a systematic and evidence-based
development strategy for the agricultural sector of the
country as a whole and on the regional level. In this
regard, the study presents an analysis of the main
indicators of the Program of development of
agriculture of Russia and the Stavropol region, as well
as their comparative characteristics, which allowed us
to make conclusions about the region's share in the
national indicators of agricultural development. The
authors have conducted forecasting of the major
indicators of Agriculture of Russia and the Stavropol
region. The forecast covers such characteristics of
agriculture, as the amount of output (production
component), investments in fixed capital of agro
industrial complex (investment component) and
balanced financial result (resultant component). The
composed scenarios of development of agricultural
production in Russia and the Stavropol region reflect
possible trends: inertial development of the industry,
based on maintaining the current dynamics of
development; pessimistic scenario anticipating slow pace of development of investment activity in the
agricultural sector; optimistic scenario, based on the
assumption that the creation of fundamental
conditions for public and private investment in agro
industrial complex. The results are of interest to
scientists studying the processes of development of
agriculture, and for representatives of the agricultural
business and government
Problem having elementary formulation makes us
look for its easier solution. So the combinatorial
method of positive integer’s factorization is an
attempt to do it. The combinatory method possesses
simple algorithm, leading immediately to finding out
all the factorizations and identification of all prime
numbers on any interval of the positive integers.
Prime numbers don’t carry any information except
their own magnitude. Composite numbers, possessing
divisibility properties provide possibility to discover
the law of their distribution. The achievement of this
purpose also completely solves the problem of
finding out the law of prime numbers’ distribution
The present level of development of power systems,
the need to increase their resources and increased
competition have caused especially true problem of
increasing the efficiency of their operation. The work
is devoted to the justification of the selection and
development of a technique of construction of the
diagnostic model to search for failures in power
objects
The article considers the internal and external forms of phraseologisms: the combinability of the component bïha in the phraseologisms of the Sakha language and their connections and relations with the surrounding words
Photovoltaic devices are a promising solution
to the energy crisis, because they generate
electricity directly from sunlight, without
producing CO2. While color-sensitized
batteries are the most studied element, mainly
due to its low cost and high efficiency solar
energy conversion into electricity. Until
recently, the color-sensitized solar cells
performance was less than 1%, however, the
use of titanium dioxide as the anode material
have greatly raised their efficiency. The
advantages of titanium dioxide is primarily in
the low cost, but its use provides high light
capture efficiency, with external quantum
efficiency (efficiency incident photon -
charge), usually in the range of 60-90% using
nanocrystal forms in comparison with
The article is fulfilled in the frames of modern linguistic studies where the cognitive aspects of language activities are actively studied, concept researches are conducted and is devoted to the study of color words in the design of color picture of the world of different language cultures and their role and function in formation of special language terminology. The authors analyze compound terms and their definitions of a new emerging trend of the economy – green economy, borrowed from the materials of UN organizations and Institute of Green Economy and reveal that the color word green participates in terminology formation due to metaphoric use, as an indirect nomination that gives way to sense increment. Color words bear assessment charge that is realized in terms formation through complex attributive combinations. The ambivalence of the semantics of color is demonstrated through opposite meanings and this allows conclusion that color words are connected with emotional and volitional state of a person, society and that they are perceived in a figurative, non-color, but psychological, emotional meaning and due to this ability they are able to form mental formation in professional field
In this article, we investigate the restricted problem of
many bodies with a logarithmic potential in the general
theory of relativity. We consider the metric having
axial symmetry and containing a logarithmic
singularity. In numerical calculations, we studied the
properties of the gravitational potential in the problem
of establishing a static condition in which multiple
singularities retain the initial position on the axis of the
system. This is achieved due to relativistic effects,
which have no analogues in Newton's theory of
gravitation. The motion of relativistic particles in a
logarithmic potential sources distributed on the surface
of a torus simulated. It is shown that the trajectory of
the particles in these systems form a torus covered with
needles. It was found, that the Ricci flow in the general
theory of relativity could be born three kinds of matter -
positive and negative energy density, as well as the
color of matter, the gravitational potential of which is
complex. It has been shown that this type of material is
associated with the manifestation of the quantummechanical
properties, which is consistent with the
hypothesis of the origin of Schrodinger quantum
mechanics. It is assumed that the most likely candidate
for the role of the color of matter is the system of
quarks as to describe the dynamics of quarks using the
logarithmic potential, and the quarks themselves are not
observed in the free state
Dispersed colloidal particles pertaining to positive colloids is played important role in the process of the interaction of organic wastes (sewage sludge, defeca-tion mud, chicken manure, etc.) with various wastes of mineral raw materials (phosphogypsum, lime powder, halite, etc.)
