ABSTRACT: The authors note that recent experiments to determine the. age of
neutrons in water indicate satisfactory agreement between the value of 26.0 + 0.5
CM2 given by Kh. Gol'dahteyn, P. Taveyfel and D. Foster (Trudy* Vtoroy mezhdu-narod-

Yurova, A. A. Polyakov, and A. A- Xgri~itov (Novy*ye i7zmereniya vozrasta neytz-onov v
vode. "Atomnaya energiya", 10,, no. 2, 1961) and by XAmbard and Blanchard (Nucl.
Sci. Engng, 7, 5, 1960)6 respectively. It is pointed out that the rated and
experimental data converge, if the dependence of the spatial distribution of the

slowed neutrons on the effect of the absorption of these neutrons in the source is
considered during the experiment. However, tho last two papers mentioned contain
no calculations confirming the existence of this dependence. In the proment paper,
an estimation of this effect Is given on the bamis of a concrete example. An
infinite laminar source, with thickness d, in considered. The material of the
source is U-235. The flow distribution from the right-hand side of the source
(x >,,O) is found. All the neutrons are broken down into three energy gvoupa and
the assumption is introduced that the laminar source absolutely does not absorb
neutrons with energy greater than 1234 av. An expression for the spatial dis-
tribution of the stream is derived, after which the neutro age with different
source thicknesses can be "oily computed. For a plain (flat) case, whon

The authors note, in conclusions that absorption of slowed neutrons in the source
may have a substantial influence on the spatial distribution, with th6 lattarl in

ABSTRACT: In an earlier authors' work Izv. AN.SSSR, Tekhnicheakaya kibernetika,
1965, no. 1), a method was suggested for determining the weight function of an
optimal filter from a sob~tion of-an Euler ~Iifferential equation. the latter belonged
with a variational problem that hadr.proper.-r formulated boundary conditions for the
case when the'deoirable signal' m(t). and noise n(t) were described by differential'
eIquations which set the connections with the initial white noise V. (t) and V, (t). The
present article applies the above method to solving the problem ol optimal filtration

signal and noise are not correlated. The method is easily generalized to cover
problems with specified-shape Inpu-t signals; in the unbiased-estimator problem, the
Euler differential equation for the weight function I of the filter part being optimized
degenerater into an algebraic equation. In the biased-eotimator problem, the form
of solution. -_~ r-,%e Integral equation for X does not differ from that of the nonbiased-

TITLE: Solution of the optimal filtration problem for random ni al' whose proper-

SOURCE: Artonatika i telemekhanika, no. 3. 1966, 4o-47
TOPIC TAGS: filtration, opti-1 filtration, optimal filter, Euler equation, random
signal
ABSTRACT: A method is presented for determining the optimal filter for input signals
consisting of the useful signal M(T) and of the noise n(T) which are random functions
of time and whose statistical characteristics on the given intervals of time (to, t11
(t1' t2) ... (tN-11 tN) are different. These characteristics are described on every
interval by given differential equations. The problem is reduced to determining
the weighting function of the optimal filter in the form
g 0' -1) gA (t. .1)
under the assumption that weighting function gk(t, -r) is nonzero on every interval

of the sequence of intervals. An estimate.m*(t) of the useful signal at the output
of the filter is derived and the filtration error c(t) is established. An expres-
sion for the variance DC(t) of the filtration error-is formed, and the weighting
function minimizing the variance D (t) is sought. Determining the optimal veighting
functions is reduced to the solutfon of a system of -%~'~Iervs differential equations.
Solutions of these equations contain a certain number of arbitrary constants as well
as a certain number of parameters; a complete system of algebraic equations is
derived for determining these parameters. The method is illustrated by an exaWle.

ABSTRACT: The problem of the characteristics of an optimal filter weighting function g(t,
when t -- is considered. The fundamental assumption postulated by the authors consists iw
defining the useful signal m(,r) and the noise n(-r) by differential equations which link them with
"white noise." It Is demonstrated that regardless of the stability of the solutions of these
differential equations, an optimal filter at t, - Is stationary and asymptotically stable.
Formulas are derived for the determination of the optimal weighting function for this particutar
case. A maximum limiting value for the error spread Is found. An analysis to given for I the&

ABSTFUCT: Thin films of All Al-Fe alloys and also NiO-Cr 0 and
NiO-Al2O oxides were heated in air and the resulE4 changes
were followed electronographically. The metal films weVe
formed by vacuum evaporation to a thichness of 400-500A; in
the case of the alloy-two sources were used simultaneously.
The films were formed on mica, removed in water and trans-
ferred to a microscope grid on which the oxidation was carried
out. For the mixed oxides further layers were deposited by
evaporation. The thicknesses were calculated to give the
stoichimetric compositions NiAl 04 arA NiCr2O4, An Al film
was heated in air at 300 0 for 9 hours and at 400, 450t 500,
F,C* and 700 C for 10 minutes. At 300 there is significant T'-

ABSTRACTt Tablets were pressed of 0(-Al20jjs oL -Cr 0 oxides and mixtures in a
stoichiometrio relation for spin (N101~9 J - 1 and N101A1201 - 1).
The tablets were subsequently sinter9d, 'iR lotive layer of 0.1 to I&
thickness was applied by the method of evaporation in a vacuum. The
thickness of the layer waa determined from the growth of weight, Diffusion
annealing was carried out in quartz tubes or ampoules in a vacuum 0V 10,2

investigated by removing the layers. All experimental IS D points (D in

AB3TRACT: This investigation was conducted for the firat time and was
initiated on the one hand by contradictory results. on the
other hand by the uncertain structure of zirconium-oxide
films in the corrosion in oxidizing media. The various pos-
sible modifications of ZrO 2 were discussed by Luatman
(Lastmen, Ref i). From other papers prcceeds (Refs 2 - 5)
that undoubtedly two forms of Zr02 exist: a monoclinic and
a tetragonal~ which interchange reversibly at from 1000 to
0
1100 " The authors investigated ZrO films with a thickness
of from 400 - 600 a electronographigally cn goinf! thrcueh.
A special device permitted the observation of structural
modifications of ZrO in dependence on temperature and on
Card 1/4 the heating period directly in the electronograph, and that

without cooling the sample* This device is described. Thece
J ext3eriments showed that in the evaporation a very careful
procedure must be adopted. Special attention must be ' paid
to the vacuum in the systemo as Zr reacts actively with
the residual gases in melting, and produces partially oxidiz-
ed filmg in an insufficient vacuum (10-5 of mercury column).
The results are given as eleotronographs (Tables I and 2 and
Fig 2). From the electron ograph 2a for a thin Zr-layer and
from the corresponding Table 1 can be seen that the values
of interplanar spacing of the crystal lattice of this layer
correspond to a-zirconium. They are hov:ever, greater by
from 2 in comparison to the X-ray dat%, The increase
of the lattice constant is apparently connet:ted with the
dissolution of oxygen in the zirconium film. The analysis
of the electronograph (Fig 2 and Table 2) fw a zirconium
film, which was heateA thoroughly up to 3000 # shows a com-
plete oxidation. The diffraction pattern corresponds to the
A
cubic modification of ZrO,# . Lhe Tue ef the lattice
constant of this modification a - 500 correeponis well
with the value determinediby X5ray methoin. (Ref 1). kt

the elgetronograph become aharper asd cerrespond to the men-
tioned cubic modification, From 650 upwards some of the
rings begin to double, which indicates the appearance of a
new ZrO -modification in the layer. It shows a tetragonal
lattict-2(Fig 2c for 7000 It io difficult in this case to
speak of the existence of two forms of ZrO. (a oubic and a
tetragonal one) as the transition from one to 0another apparent-
ly takes place gradually. Between 750 and 800 lines of the
monoolinio modification appear besides the lines of the
tetragonal modification. They increase in intensity until
at 11000 the tetragonal modification is completely dis-
placgd. The monoclinic modification is maintained up to
1300 , These transformations were observed in a vacu~3m, in
oxygen and in air. The polymorphous transformations are
therefore not the reault of the oxygen dissolution or of
the arrival of ZrO2 at an exact otoichometrival composition#
