Abstract: The article presents a description of alleged approaches to the implementation of data processing
subsystem on Internet portal. Main problems are connected with exponential growth in number of documents,
lack of semantic indexing and unstructured nature of information. In proposed approach, user receives an
effective intelligent means of finding electronic documents on the basis of semantic indexing, automatic
classification and cataloging of documents with construction of semantic links between them and automatic
summarization of documents with the use of knowledge. The proposal is to increase the effectiveness of working
with electronic documents with the help of intelligent analysis, for which agentbased and ontological approaches
are used. In accordance with the proposed approach, ontology is used to describe data semantics of the
document and its structure. Ontology is a central concept in process of document analysis. Through the use of
ontologies the required data can be obtained; we know where to find information and how it can be interpreted.
Ontology Repository contains three levels of ontologies. At the first level there are ontologies describing objects
which are used in a particular system and which take into account system features. At the second level there are
objects described in terms of the first level that are invariant to the domain. Objects of the third level describe the
most general concepts and axioms, by which the lower levels objects are described. The third and second levels
can be divided into two parts: a description of structures and description of the documents themselves.

Abstract: The paper discusses stability concepts and methods of stability investigation in models describing the
climatebiosphere interaction for a hypothetical zerodimensional model. The climatebiosphere model proposed
by Svirezhev& von Bloh, 1997, exhibited interesting features concerning the stability and sensitivity to
perturbations of the global system. The work is focused on the determination of transition times between the
equilibriums due to random perturbations. In investigate bifurcations in the model to describe complex behavior in
the model with multiple equilibriums. Global vegetation pattern dynamics strongly depends on production and
hence evolutionary models must explicitly use this concept. We have shown analytically that GVP dynamics could
demonstrate complex behavior with multiple equilibria, chaotic dynamics associated with them as well as
transition zones between consequent states.

Abstract: In this paper, a novel method for image orientation angle determination is proposed. The method is
based on the use of parameters of scattering ellipse of an image gradient field. Various problems with application
of the proposed technique are considered. The results of the experiments for determining the predominant
direction of an image are presented. Three methods of image orientation angle (OA) estimation are compared. It
is shown that the method based on scattering ellipse technique is more precise than the histogrambased
methods. The term of the "backlash" of image rotation algorithms is submitted and a method for “backlash”
estimation is proposed. The “backlash” can be used for determination of the quality of arbitrary rotation algorithm.
It is also shown that the proposed technique can be applied to the problems related to the Horizon line tracking.

(1.00/10)

Abstract: This paper is devoted to study of characteristics of logarithmically asymptotically optimal (LAO)
hypotheses testing and identification for a model consisting of two related objects. In general case it is supposed
that L1 possible probability distributions of states constitute the family of possible hypotheses for the first object
and the second object is distributed according to one of L1 × L2 given conditional distributions depending on the
distribution index and the current observed state of the first object. For the first testing procedure the matrix of
interdependencies of all possible pairs of the error probability exponents (reliabilities) in asymptotically optimal
tests of distributions of both objects is studied. The identification of the distributions of two objects gives an
answer to the question whether 1
r th and 2r th distributions occurred or not on the first and the second objects,
correspondingly. Reliabilities for the LAO identification are determined for each pair of double hypotheses. By the
second approach the optimal interdependencies of lower estimates of all possible pairs of corresponding
reliabilities are found and lower estimates of reliabilities for the LAO identification are studied for each pair of
hypotheses. The more complete results are presented for model of statistically dependent objects, when
distributions of the objects are dependent, but its current states are independent. For an example of two
statistically dependent objects optimal interdependencies of pairs of reliabilities are calculated and graphically
presented.

INTERFERENCE MINIMIZATION IN PHYSICAL MODEL OF WIRELESS NETWORKS

Abstract: Interference minimization problem in wireless sensor and adhoc networks is considered. That is to
assign a transmission power to each node of a network such that the network is connected and at the same time
the maximum of accumulated signal straight on network nodes is minimum. Previous works on interference
minimization in wireless networks mainly consider the disk graph model of network. For disk graph model two
approximation algorithms with O( n) and (( ln ) )
2 O opt n upper bounds of maximum interference are known,
where n is the number of nodes and opt is the minimal interference of a given network. In current work we
consider more general interference model, the physical interference model, where sender nodes' signal straight
on a given node is a function of a sender/receiver node pair and sender nodes' transmission power. For this
model we give a polynomial time approximation algorithm which finds a connected network with at most
(( ln ) / ) 2 O opt n β interference, where β ≥1 is the minimum signal straight necessary on receiver node for
successfully receiving a message.

Abstract: A Тcomplete wttmitotic set is composed, which is not ttmitotic. A relation is found out between
structure of computably enumerable sets and the density of their unsolvability degrees.
Let us adduce some definitions:
A computably enumerable (c.e.) set is tt  mitotic (wtt  mitotic) set if it is the disjoint union of two c.e.
sets both of the same tt degree ( wtt degree) of unsolvability.
Let A be an infinite set. f majorize A if ( ( ) ) n ∀n f n ≥ z , where z0 ,z1, are the members of A
in strictly increasing order.
A is hyperimmune (abbreviated himmune) if A is infinite and (∀ recursive f ) f does not majorize A.
A is hypersimple if A is c.e. and A is hyperimmune.
A is hyperhyperimmune if A is infinite and ¬(∃ recursive f ) so that
[( ) &( )( ) ∀u Wf (u) is finite & Wf (u) A ≠ ∅ ∀u ∀v u ≠ v ⇒Wf (u) Wf (v) = ∅ ].
A is hyperhypersimple if A is computably enumerable and A is hyperhyperimmune.
We shall denote Tdegrees by small bold Latin letters.
A degree a ≤ 0′ is low if a′ = 0′(i.e. if the jumpa′ has the lowest degree possible).
Theorem (Martin 6). a is the degree of a maximal set ⇔ a is the degree of a hypersimple set ⇔ a
is c.e. and a′ = 0′′ .
Theorem (R. Robinson 8). Let b and c be c.e. degrees such that c < b and c is low. Then there
exist incomparable low c.e. degrees 0 a and a1 , such that 0 1 b = a ∪ a and a > c i , for i < 2 .
Griffiths (3) proved that there is a low c.e. Tdegree u such that if v is a c.e. Tdegree and u ≤ v then
v is not completely mitotic.
In this article it is proved the following theorem:
Theorem. There exists a low c.e. Tdegree u such that if v is a c.e. Tdegree and u ≤ v then v contains
hypersimple wtt mitotic set, which is not tt mitotic.
From the abovementioned theorems of Martin and R. Robinson follows that it is impossible to replace
hypersimple by hyperhypersimple.

ON THE STRUCTURE OF MAXIMUM INDEPENDENT SETS IN BIPARTITE GRAPHS
By: Vahagn Minasyan

Rating:
(1.00/10)

Abstract: In this paper it is shown that for bipartite graphs the structure of the family of maximum independent
sets can be described constructively, in the following sense. For a bipartite graph there are some “basic”
maximum independent sets, in terms of which any maximum independent set can be described, in the sense that
there is onetoone correspondence between a maximum independent set and an irreducible combination of
these “basic” maximum independent sets. König’s theorem states that there is duality between the cardinalities of
maximum matching and minimum vertex cover. Viewing the mentioned structure, in this paper it is shown that
another duality holds, which is between the sets rather than their cardinalities. We believe that this duality is not
just of theoretical interest, but it also can yield to a usable algorithm for finding a maximum matching of bipartite
graph. In this paper we do not present such algorithm; instead we mention what approaches we plan to use in
further works to obtain such algorithm.

Abstract: It is known that the minimal number of the steps in a proof of a tautology in a Frege system can be
exponentially larger than in a substitution Frege system, but it is an open problem whether Frege systems can
polynomially simulate substitution Frege systems by sizes. Many people conjecture that the answer is no. We
prove that the answer is yes. As a bridge between substitution Frege systems and Frege systems we consider
the Frege systems, augmented with restricted substitution (single renaming) rule. We prove that Frege systems
with single renaming rule polynomially simulate by size Frege systems with substitution rule without any
restrictions, and Frege systems without substitution rule polynomially simulate Frege systems with single
renaming rule both by steps and by size.
