Abstract: The method used to increase the accuracy of hue reproduced in polygraphy is
based on application of equicontrast graded transformation of hue scales in color
space of \standard" observer. A similar problem is considered for the color space
of arbitrary personal computer user in case of color representation to computer
monitor. The proposed method is based on application of personified graded
equicontrast transformation of hue scales. The examples to illustrate the efficiency
of the method are provided.

Abstract: A procedure for characterization of the standard cells (extraction of time and
electrical parameters for creating functional model) intended for self-timed circuit
design is presented. It is shown that specific behavior of self-timed circuits
additionally constrains characterization process as well as leads to changing the
values of some parameters of a cell model. A software tool for standard cell
characterization and the results of its beta testing are described.

Abstract: The problems related to fixation and handling of exceptions in the multicore
dataflow computing system are identified. Possible variants of exceptions detection
and debugging information generation for its transfer on processing are analyzed.
The principles of fixation logic creation and exceptions handling, applicable for all
kinds of computing systems, are formulated.

HIERARCHICAL METHOD OF THE ANALYSIS OF SPEED-INDEPENDENT ELECTRONIC CIRCUITS.
- L. Plekhanov IPI RAN, LPlekhanov@ipiran.ru
Abstract: Development and implementation of speed-independent circuits possessing unique
properties are largely discouraged by design difficulties, in particular, the analysis for speed-independence of "large" circuits. A method of the analysis of circuits of
unlimited size based on the functional approach is suggested. In the literature, such
approach and method are not observed, and the method is proposed here for the first
Keywords: speed-independent circuits; self-timed circuits; analysis for speed-independence
THE FAULT TOLERANCE INCREASING OF CACHE-MEMORY DATA BY THEIR REFRESHING.
- B. Shmeilin IPI RAN, email@example.com
Abstract: For reducing vulnerability to transient failures of cache-memory data, a refresh
method is suggested. The data refreshing planning is based on the applications code
analysis at compilation stage. The method is applicable to linked data structures that
is shown on arrays and nested structures. The data refresh planning is demonstrated
by an example of the matrix multiplication program.
Keywords: microprocessor systems; cache-memory data; vulnerability to transient
failures; linked data structures
LEXICAL SEMANTICS MODELING IN THE TASKS OF COMPUTATIONAL LINGUISTICS.

Abstract: An analytical review of lexical and semantic methods, their examples, and spheres
of application is presented. Among the considered articles, those published in the
2009 and 2011 Proceedings of The World Congress in Computer Science, Computer
Engineering, and Applied Computing were chosen.

Program-oriented indicators: Production and application in science.
- I. Zatsman IPI RAN, email@example.com
- A. Durnovo IPI RAN, firstname.lastname@example.org
Abstract: The results of the project, whose goal is to create a tool for
developing sets of indicators for monitoring and evaluating
research and developments (R&D) program activities are presented. Each
set of developed science and technology (S&T) indicators is oriented at
the assessment of only one R&D program, i.e., at its objectives, resources, and results. The tool for developing indicators is being
designed as an experts knowledge base named the proactive dictionary, which is the
component of the evaluation system. This component enables experts to fix stages of
indicators development, to present the results of developing different variants of indicators
in graphic form, to compare and evaluate those variants, which are oriented at objectives,
resources, and results of R&D program activities. The paper describes two theoretical
models of the process of indicators development. It also describes a prototype of the
proactive dictionary created on the base of these models. Finally, it describes the results of an
experiment of development of a set of indicators by a group of the experts.
Keywords: processes of experts' knowledge creation about indicators; knowledge
representation about indicators; semiotic models; program-oriented indicators;

Abstract: The semantic-oriented linguistic processor which extracts the knowledge from
natural language texts and forms the structures in the Knowledge Base is considered.
Significant part of this processor is the block of lexical morphological analysis
including the subject vocabularies. The paper discusses the direction of development
the vocabularies which are used to analyze the context of words and assigns new semantic signs for them. It gives the possibilities to eliminate various ambiguities in
the process of syntactical semantic analysis.
Keywords: knowledge extraction; linguistic processor; lexical morphological
analysis; subject vocabulary
