82048 The Possible Cause of the Change in the 3/05o/60/000/07/02/002 Relationship Between the Sun and the B019/BO63 Terrestrial Atmosphere 82040 that solar activity has different effects on atmospheric circulations, Magnetic storms on the Sun had differer~ effects. Next, the author gives data on violent and very violent~-mnTnptin stnrma between 1900 and 1939. The examples given here, supp.Lemented by various diagrams (Figs. 1 and 2), indicate that an increase in solar activity may have different effects upon the processes taking place in the lower strata of the atmosphere. Mention is made of M. S. Eygenson's (Ref. 7) and A. 1. 0118 (Ref- 4) discovery of cyclic variations in the hardness and direction of the corpusoular radiation of the Sun, and it is noted -that the type of change in the relationship be',ween the Sun and the atmosphere is thus also dependent on the rotat:Lon of the Sun. This hypothesis is now being verified with material.fr6m the International Geophysical Year. There are 2 figures and 7 Soviet references.

The products obtained on the stretching apparatus are characterized by high strength and can be applied in various indus- trial fields. The relationship between the hardeners and the process- ibility of resin on the continuous apparatus is investigated for a styrene-epoxide compound at a hardening temperature of 140 C. The properties of the styrene-epoxide compound with different hardeners Card 1/2 ACCESSION NR: AP4009835 are tabulated. The influence of new lubricants, As-1, AF-1, WE, PVE-3, on the strength of glass plastic was investigated. The rela- tionship between the strength of glass plastio pipes under axial com- pression and the glass filler content is esta*jlished. Suggestions for the best choice of binders, lubricants and fillers are given. Glass plastic rods of small diameter made on the continuous machine have a high breaking strength similar to the strength of steel cables. Orig. art. has: 2 tables.

Me most usual were studies of the blood pressure following a subcutaneous injection of acrenalin and observations on dermographism. The blood pressure reaction was aberrant in 59.6% and dermographism was weakened in 53.2% of the cases.

A distinction is made between manual and auto- matic zero adjustment. The latter may be a single- or group ad- justment. A middle course is the t~utomatic control with subse- quent manual zero adjustment. The principle of the zero adJuat- ment control by groups is based on the consecutive measurement of the zero drift voltages by mearis of a zero Plement. Since the zero drift voltage in direct currnnt amplifiors varies but slowly, such a method An acceptable for models of mean accura- cy. In all known systems the zero adjustment control is carried Card 1/3 out with mechanical commutatora by means of step for step Witxh- Group Systems of Automatic Control and Zero Adjuatment S071/lig-c9-6-1/18, in Direct Current Amplifiers of Electric Models es. Constructions are shown for an exemplification, which were worked out in the electromodel department of the IIIISohetMash (Nauchno-isaledovatellskiy institut schetnykh mashin - Scien- tific Research Institute of Compui;ers). Figure 10 shows the cir- cuit diagram of the electromechanical system of the automatic zero adjustment in the electric models MN--2 and MN-3. The am- plifiers are subdivided in-groupa of 25 each. The ?ero adjust- ment is brought about by the motion of the slidir.r, -cntact of a potentiometer; this motion is released by a relay of the zero element. Fig--,re 2 shows the circult diagram of an electronic system, as is applied in the model MN-9. A similar system has been appliea in the model MN-Il. rhe step for step compensation of the zero drift voltage occurs by a change in potential on the second grid of the tube over a condenser. When using ampli- fying tubes with a good zero stability, the zero adjustment for the solution of problems which do not require great acnuracy, may take place within longer periods of time. The automatic control of the zero adjustment with subsequent manual control is then recommended. Figure 5 shows such a control circuit for Card 2/3 electric models with 300 - 400 amplifying tubes. S.

The author urges im.~: provement of each of these characteristics, but not at an excessive cost in compli-. .cation inconsistent with the purpose of the AC; for ex~tmple, an aircraft flight I ! , ;simulator can operate satisfactorily even without automatic null-drift compensation. 'The significance of each of the aforestated charactf-ristics, means for their reason- ,able improvement, and interrelationships between the characteristics and the 9 employed to control them are explained. The limits of the admissible mag 'mean Initudes of some of the unde'sirable characteristics are explored for various "ecific applications. Periodization of solutions, as a rule, leatis to a reduction of the time scale, which in turn leads to a direct increase of the error. Z. On some supple- jnentary errors of AC's operating in a periodic- solution. regime: In addition to the 'increase of an error attributable to the use of a periodic solution per se, the dyna ;mic properties of the RE operating at a faster rate leads to the appearance of a systematic error in the solution.

If the employment of mits its enlargement and refinement, then the improvement in accuracy achieved, thereby is worth the additional complication of commutition; the balance of cost' and accuracy must be closely watched, (b' multiple utilization of groups of RE's 'hat perform complex computational operations which do not contain integration operations and do not employ the method of implic:.t functions. Examples: coordi nation transformations or ai rc raft- powe rplant thrust computations (references cited); (c) multiple employment of groups of RE's for the performance of iterative, computational operations both including a number of external noncommutative ele-, ments and with the use of the method of implicit functicns within the multiply em- ployed system. Examples: Machines for the soluAons of systems of transcenden-, _1_ tal, algebraic, and integral equations (references); (d) multiple utilization of RE ,19, 1 for the formation of derivatives in the solution of cystems of ordinary linear and nonlinear differential equations.

The paper proposes to Improve the quality of the isearch and to accelerate it by means of the use of an averaged estimate of the de.~ ~viatfo*ns A so that the probability of a spuricus signal can be reduced. Difficul' :des encountled with the use of the averaging motho~'. are related. The algorithm -;employed on the AC MN-11 is explained and graphically illustrated. Several illu ;trative exarnplps are set forth, and it is concluded thiat In a search by the minimiza- tion method with a constant magnitude of the increment it is advisable to employ the average estimate of the quantity Ali; here the increase of the total number of solu- tions does not lead to a eubstantial change of the operational possibilities of the MN-11 machine, which exhibits a sufficiently large frequency of the periodization of ; -11 machine stemming from its solutions. One of the principal qualities of the MN high speed and the autornization of its search for suitable solutions appears to be its capability to solve unstable problems with groat changea at the ends of the solu- tion intervals for small changes of the varied pa.-ameters. The application of the averaged estimate of the quantity AIL increases these capabilities of the MN-11 machine even further and improves its effectiveness in the investigation of its capability for the control of "unstable" technological processes in the predictive analytical regime.
