Boris Vladimirovich
Gnedenko (Russian: Áîðè́ñ Âëàäè́ìèðîâè÷ Ãíåäǻíêî;
January 1, 1912 – December 27, 1995) was a Soviet mathematician
and a student of Andrey Nikolaevich Kolmogorov. He was
born in Simbirsk (now Ulyanovsk), Russia, and died in Moscow.
He is perhaps best known for his work with Kolmogorov,
and his contributions to the study of probability theory,
such as the Fisher–Tippett–Gnedenko theorem. Gnedenko
was appointed as Head of the Physics, Mathematics and
Chemistry Section of the Ukrainian Academy of Sciences in
1949, and also became Director of the Kiev Institute of
Mathematics in the same year. Gnedenko was a leading
member of the Russian school of probability theory and
statistics. He also worked on applications of statistics
to reliability and quality control in manufacturing. He
wrote a history of mathematics in Russia (published
1946) and with O. B. Sheynin the section on the history
of probability theory in the history of mathematics by Andrei
Kolmogorov and Adolph P. Yushkevich (published 1992). In
1958 he was a plenary speaker at theInternational
Congress of Mathematicians in Edinburgh with a talk
entitled "Limit theorems of probability theory". We
publish his short memoir and updated bibliography.

A METHOD OF A PRIORI SOFTWARE RELIABILITY EVALUATION
In the given paper a
method of a priori evaluation of the amount of latent
faults, the estimated latent defect density and their
determination probability in Software before testing
process is described. The possibility of the method
usage for different schemes of the Software development
process has been found. The a priori estimation of these
reliability indexes makes the management decisions at
the stage of testing more effective.

OF ELECTROPOWER SYSTEMS
Existing comparison
criteria average values of random variables of general
population cannot be used at comparison of average
random variables of multivariate data. The method,
algorithm and an example of calculation of critical
values recommended statistics offered.

UNCERTAINTY OF PROBABILITY COMPONENT OF ACCIDENTAL RISK
Concept of accidental
risk is intended to be an objective measure for
assessing the risk of accidents in the technosphere.
Metric of risk should combine estimation both
probability (possibility) of the accident and the damage
it caused. For various reasons, any parameter of risk
has uncertainty. The problem of uncertainty quantifying
arose very early in the study of accidental risk. Often
used in practice dotted (scalar) estimation of
probabilistic component of risk metric are in most cases
inadequate since embody great internal uncertainty.

RELIABILITY BASED METHODOLOGY FOR VENDOR SELECTION - A CASE
STUDY
The objective of
every industry is to manufacture and supply products
that will perform its intended functions without fail in
the actual field. A reliable design (there is a
misconception that a reliable design will always give a
reliable product) may not necessarily turn out to be a
reliable product always. Even if a product having
reliable design is manufactured and used in the field
its reliability may be unsatisfactory. The reason for
this low reliability may be the product was poorly
manufactured by using substandard manufacturing
processes. Therefore to produce a reliable product,
evaluation of manufacturing processes or vendors is
necessary. In this work an attempt has been made to
formulate a methodology which will help in evaluating
the design reliability as well as the vendor selection
process. The proposed methodology includes reliability
prediction to effectively predict the design reliability
and HALT (Highly Accelerated Life Testing) for vendor
selection by qualitatively comparing the prototypes of
same design manufactured by different vendors. A case
study on a power electronic product is included to
explain the methodology.

OPTIMUM LIKELIHOOD QUANTIZATION OF THE INFORMATION IN SPACE
WITH RESTRICTION OF ZONES OF INFLUENCE OF QUANTA
The model of optimum
three-dimensional likelihood quantization of the
determined or casual volume space is offered by set of
equal quanta at which the probability of representation
quantized reaches spaces of the maximum value. The size
of optimum quantum is defined by distribution of its
zone of influence, values of boundary probability and
influence parameter. The model of estimation of quantity
of the information or other product in quantization
space is entered.

EXPERIMENTAL STUDY
OF THE REPAIRS OF HYDROPNEUMATIC PARTS OF COMPLEX TECHNICAL
OBJECTS
Hydropneumatic part
of each complex technical object has its own specifics.
It determines the specifics of the repair work on that
part. Based on possesses collected information from
experimental study about the failures in hydropneumatic
part of a typical complex technical subject - machine
tool by CNC. Synthesized are conclusions and
recommendations for enhancing the effectiveness of using
recreational events.
