In a previous article (ibid. 83, No 6 (1952)) tb~
authors discussed a new method for determining the
hydromechanical effect of a channel grcove or slot
for the case of infinite depth of the vater perme-
able layer. In this article they discuss the method
for the case of finite depth for certain assumptions-

PERIODICALs IJkrainskiy matematicheskiy zhurnal.1953vVol 10,Nr 3v

ABSTRACTt The method already formerly applied by the author [Ref 31
in special cases consists in the following : A triangle is
circumscribed about -the polygon given so that they have in
commion one corner and a part of the sides. The triangle is
mapped onto the plane so that the c3mmon angle comes into
the infinite point. Then a half plane wiih a series of
sectors corresponds to the polygon. These sectors are
eliminated with the aid of corresponding elementary mappings,
whereby it is possible to determine arbitrarily exactly the
constants of the Christoffel - Schwarz integral. The
method can be modified for open polygons too.

The Theory of Percolation (Cont.) SOV/5637
The calculation method discussed in Vol. I Is based on the theory of
Academician N. N. Pavlovskiy. Application of the approximation methcds
of Academician M. A, Larrentlyev to this theory makes possible 1) the
solution of a problem set for homogeneous soil in the most general form.,
i.e., for a weir foundation with a practical profile and arbitrary line
of bed-level;and 2) the development of a grapho-analytical method of
computing filtration., which permits calculations of uplift pressure, velocit
of retre at , and discharge for any apron with a practical profile and
with finite and infinite depths of permeable soil to be carried out In
20-30 minutes. Basic regrilts of this work were presented and discussed
several time during the seminars of G. N. Sevin and A. Yu. Ioblinskly in
the Department of Technical Sciences., AS VkrSSR, The author thanks R. V.

ABSTRACT: The authors introduce the application of thin linear bars
for the realization of functional boundary conditions of
the first kind (Dirichlet's problem) in modelling on
resistant paper, and describe the technique of their pre-
paration. In the majority of cases the conditions tLader
which the potential u - const. or

are sufficient for the realization of boundary conditions
in modelling on resistant paper, of the bulk of problems
arising in the theory of filtration, hydro- and aerolynamics,

approximations to equivalent boundary conditions of the let
kind. The modelling on resistance paper of boundary problems
of functional boundary condition (1) can easily be achieved
with the use of thin linear rods, which are prepared as
follows: PEB-1 or PEM-1 copper enamel wire 1.2 - 2.0 mm.

and wound around with PEShOM or PShDhI manganin wire, or
PEShOK or PShDK constantan wire 0.12 - 0.20 mm. The winding
is then soaked with a 1:1 solution of BF-2 glue and spirit,
polymerized in a drying chamber for 1 hour at 100 - 1200C,
then polished with a fine emery cloth. Then the wire is
provided with lengths of thin multicore cable (MGShD, MGV-
0.20, or other) for connection to assigned potentials,
attached to the wire ends and interjacent sections. Now the
rod is glued onto the resistame paper model, with an electro-
condactive glue consisting of 35 g of dope, 1 g of BF-2 glue
and 7 9 of carbon black. At first the glue is applied to the
lower part of the rod, which is then put on the resistant
paper and pressed to it, whereupon the glue is applied to
the outer part of rod, and the latter is left for 3 - 5
minutes, to take hold. The authors demonstrate the applicat-
ion of the prepared rods for the solution of two problems,
Card 3/4 for illustration. Tables 1 and 3 show the correlation of the

the electric analogy of u e for control problems 1 and 2 :re-,
spectively, with boundary conditions of the lst and 3rd
kinds. The precision obtained is quite sufficient for the
modelling of many technical problems. Figure 2 presents a

1 in the case of heterogeneous medium and shows the measuring

(USSR)
ABSTRACT: Starting from the methods of the Academician 11.1f.Pavlovskiy
(conformal mapping) the author obtains a strong hydrodynamic
solution for the general case of a flat split apron under the
assumption that the porous ground is homogeneous and infinitely
deep (T = co). The author gives explicit formulas for the
characteristic terms. He considers special cases (flat aDron with
band drainage, flat apron with a flat split in the upstream apron',
drainage!or upstream apron split of arbitrary form). The solution
in the case T.
