WORK OF SEMINAR ON PRECISION MECHANICS AND CALCULATING TECHNIQUES
The seminar on precision mechanics and calculating techniques, directed by
Academician I. G. Brcyevich, began January 1946 and was held in the Institute
of Machine Studies,Academy of Sciences USSR.
After 22 yeF,.rz there have been more than 100 studies, and more than 30
lectures have been delivered. The seminar carried on its work with the as-
sistance of the following: (1) Department of Precision Mechanics, Institute
of Machine S udies, Academy of Sciences USSR; (2) Department of Approximate Cal-
culations, Mathematical Institute imeni V. A. Steklov, A,A:ademy of Sciences USSR
(3) several laboratories of the Power Engineering Institute imeni G. M. Krzhi-
zhanovskly, Academy of Sciences USSR; and (4) several organizations from other
cities of the Soviet Union.
Those who took part in the work of the seminar included many collaborators
from the Academy of Sciences USSR and various research and planning organizations
that are occupied with the study of "calculating-solving" techniques and precision
mechanics.
The purpose of the seminar was to acquaint the various departments of the
Academy with the scientific research of other departments which it had been pro-
posed were to be united with the newly created Institute of Precision Mechanics
and Calculating Techniques.
Lectures at the seminars encompassed problems connected with the theories,
construction, accuracy, efficiency, fields of application, and the development
of all possible types of calculating-solving machines. Surveys were made of
methods of solving matt.ematical. problems by numerical, tabular, and graphical
means:

In the course of the past year the following lectures were heard and dis-
cussed at the seminar:
1, "Perforation Machines and Their Use in the Solution of Mathematical
Problems," by I. Ya. Akushskiy.
2. "An Alternati.ig-Current Calculating Table and Experimental Tabulations
on It of the Behavior of Two Modified Bessel Functions," by M. S. Libkind, S. S.
Chugunov, a nu P. I. Zubkov, co-workers from the Power Engineering Institute imeni
Krzhizhanovskiy, Academy of Sciences USSR.
4. "The Establishment of Formulas for the Approximate Calculations of
Multiple Integrals," reported by L. A. Lyusternik, Corresponding Member, Academy
of Sciences USSR, and V. A. Ditkin
in addition, I. S. Bruk, Corresponding Member, Academy of Sciences USSR,
contributed an article on "A Duplicating Apparatus of a Purely Electrical Type,"
N. V. Korol'kov, F. V. Mayorov, and M. L. Bykhovskiy gave lectures on electrical
calculating-solving apparatus. Some lectures were delivered on the accuracy of
calculating-solving apparatus. The lectures were completed in June 1948, with
the interesting communication from Luk'yanov on "Hydraulic Modeling Apparatus."
Now, after the organization of the Institute of Precision Mechanics and
Calculating Techniques of the Academy of Sciences USSR, it is proposed to con-
duct seminars on a wider basis than previously. The present seminar of November
of this year proposes the study of the following problems:
2. Mechanical and electrical modeling and solution of certain problems on
el.ectrointegrators.
3. Accuracy of various calculating-solving apparatus.
4. Problems of approximation methods in solutions of mathematical prob-
lems; problems of operational calculations and tabulation of functions.
