hours of cultivation in media with an agar

especially sharp zones Is established by one
strain of Pseadomonas "cychro", which in all
these media formed rjacrocolonies in 24 hours;
in these macrocolonies, 3 clearly circum-

Abstract: [Authors' Hunrarian summary] Based on the data of 2 years of
patient material hospitalized at the clinic for hemoptoe, the diseases are
enumerated which must be considered in a case of hemopton. The large Majority
of the patients do not have active tb. Among the tumor patients, hemoptoe
was not an early symptom. In the presence of hemoptoe of unknown etiology,
the possibility of viral or parasitic diseases of the lung as well as of
disturbances In blood coagulation must be considered more often than Is
currently done. Hemoptoe is a symptom of severe dieGass in most of the
cases. These patients must be sent without delay to the pulmonary ward
for examination or treatment. 8 Eastern European, 39 Western references,

The theory of autonomy and invariance in

TEXT; Autonomous automatic control systems with mutually
coupled multiple parameters are those in which variation of a
single control quantity affects only the corresponding controlled
parameters while the remaining parameters are unaffected, However,
noise appearing in any particular branch of the systems affects all
of them. In invariant systems noise does not affect the controlled
parameters. An ideal system is therefore one in which the
:onditions of autonomy and invariance are satisfied simultaneously,
This has been previously studied for continuous systems, but the
authors are unaware of publications on the theory of multiparameter
digital :ontrols, This is the subject of the present study,

The Lheory of autonomy and invariance.-E140/E135
The authors employ the method of analogy between the matrix
equation of a multiparameter system with the equation of a single
parameter system. The following results are obtained, In
multiparameter digital control systems the form of the control
transfer function permitting a finite number of control steps f~3
found. The requirement for a finite number of control steps
coincides with the requirement of autonomy. The autonomy
condition c;an be fulfilled only with e = 0, where c is
defined in Fig,l. After a finite number of steps the autonomy
condition can also be satisfied for c /- 0 for certain
constraints on the transfer function, The treatment of
-4nvarian~e is similar to the treatment of autonomy, It is found
'hat the invariance ~condition can be satisfied only if c = O~
The requirement of a finite number of control steps cannot be
iat-isfied in the presence of noise in the time intervals C = 0-
In order for an invariant system to be stable it in netessary
that the numerator and the denominator of the determinants of
the system matz--~x be Hurwitz polynomials, A di-tailed solution
of a numeri.-al example is presented. It is shown that the

of Sciences developed approximate methods for determining the transient

linear systems. The approximate methods involve second-order systems with
different time constants and n-th order systems with similar time con-
stants; such methods satisfy all the requirements and make it possible to
take into account transportation lags 1u order to determine the parameters
of the optimum control process for objects vhose dynamic characteristics
were already adequately approximated~ a corresponding method had to be
selected. The method of "optimum modulus" was found to be the most conveni-
ent. This method was used for single-loop systems with approximating
equations up to the tenth order and transportation lag, with all standard
types of continuous controllers. The obtained results are listed in a
table ready for use by engineera. The systems considered have usually a
monotonic transient characteristic.. If the system has no parallel loops

for Information Theory) and found satisfactory- The method of determining
the approximating functions is very simple and has been described in detail

necessary to determine the dynamic characTeristics of the various elements

then it is enough to determine the constants a., a, and #2 of Eq. (2) ;

lated~ the optimum processes for such systems can be calculated and tabu-
lated. For this purposeq the method (c titerion) of "optimum modulus,n
originally proposed by It. C. Oldenburg and H. Sartoriua was adopted. The
"optimum modulus" conditions were extended by J. MarAik to certain types
of transcendental equations. This method can be applied (in its generalized
formulation) t,3 all types of linear networks and also to networks with
transportation lag. If, however, the control time is such that the con-
trolled variable is less than � 4% of the value of the change in input
variable, then the "optimum modulus" Driterion no longer yields satisfac-
tory results: in such a case, the square in.1egral criterion has to be
used. The two criter,.d are complementary. Graphs show the properties of
the two criteria. Further. the influence of a change in the point of
application of the input variable is~ considered and of the influence of
various forms of inpat signals, It was found that for practical purposes
it is sufficient to tabulate the values of the chosen constants for the
most incoulrenient casi; this restmets considerably the number of tabulated
variables. The above simplifications make it feasible to use computer-i

the function rJ (t) in such a manner that the functions - M = ~t (t) d M
and 7p (t) = -' (t) d (t) themselves and a sufficient number of their deriva-
t

ABSTRJZT: The theory is discussed of the synthesis of linear loops with a continuousiy
operating controlled syston, and vith a discretely acting controller. The input signals
of the loop are cross-correlated random signals. It is assur-nd that the controllers,
or the discretely acting correcting riemlors, are roalizod'by an automatic computer di-,
roctly comiocted in the Ifoedback of the controlled syston. Attention is drawn to the-)
fact that the normal synthesis procedure according to the minimum of mean square
deviation may lead to physically nonrealizable transfer functions of closed con-
,trol loops. It in also shown that there are different conditions of physical
.realizability for loops designed for optimal controlling action where operative
co=ar,d signals are distorted by disturbances, and for loops designed for the
optimal compensation of disturbances where the command signala are invariable.

Thle method is demonstrated by which it is possible to decide in advance whether
the resultant transfer functions of closed control loops will or will not be
physically realizable. For the latter case a modified synthesis procedure is
presented by which it is possible to ensure the conditions of physical realiz-
abil-ity. The theory of synthesis in thls sense has been worked out in general
-for multi-paramter, linear control loops with cross-correlated input signals.
It is assumed that disturbances may act at the same points as the co=and sig-
nals, or at any arbitrary input points of the controlled system. The results
car, be easily applied to simple control loops, e.g., single-parameter loops.
In conclusion two examples are presented to illustrate the proposed modified
synthesis procedure. In both examples the normal procedure leads to a phyOcal-
ly nonrealizable sqJut;on. orig. art. has: 2 figures and 40 formulas. LBased on

ABSTRACT: The author analyzes the definition of optimum transfer functions of a
multiparameter linear, or at least linearizable with a sufficient approximation,
I hybrid control system. The term ".hybrid control system" is used here in the sense
that the controlling function is realized by discrete correcting members .(discrete
filters) on the one hand, and by continuous acting controllers on the other. The
theory of synthesis is expressed in the discrete Laplace transform and quality

control is assessed according to Wiener. It is proposed to realize the discrete
filters with the aid of a computer. It is supposed that the input signals are cross
correlated. The transfer of the command signals is partly determined by condi-
tions of stability resulting from the theory of regulation with the aid of automatic
computers described in another work (Strejc, V. : Zajisteni spolehlivosti pri
komplexni automatizaci samocinnym cislicovym pocitacem (Ensuring Reliability ip
Complex Automation by Automatic Digital Computer), Automatizace V (1962),
no. 5, pp. 123-1261. The synthesis method is illustrated in an example, given by,''
the author, which determines the optimum command transfer junction's of a two-
parameter control system with cross -correlated random stationary command
input signals of zero mean value. Orig. art. has: 61 formulas. [GCJ
