The concept is introduced of the function Ft(x), conjugate to F ;(x) , which is used to detect and correct errors by the checking numbers method. It is shown that a combination of a correcting code can be considered as a system of n = m 0 k comparisons modulo a , containing a unknowns. Methods are presented of detecting and correcting errors by the unknown solutions method and by the method of solving comparison systems. BORODIN, L.F-*,-, ZOTOVA. Ye.N.

The use of code groups in telegrams is not new but the most recent contribution to the subject has been made by a group of Czech workers (Ref 1). Methods of constructing codes which reveal and correct errors have been described earlier (Ref 2, 3, 4, 5 and 6). The cost of sending a telegram which is partly encoded is given by (2),if the number of encoded telegrams is M, then the time to encode is tl, given by Eq (7) and the time to decode is t2, given by Eq (6). Making these substitutions in (2) we find that the coefficient expressing the improvement in the system is given by (11); the improvement is greatest when this number is least. It is obvious from Card 1/4 this expression that the best conditions are those under sov/lo6-59-3-8/12 The Theory of Telegram Coding by Means of Uniform Correcting Codes which the most frequently occurring telegrams are encoded. If we suppose that the distribution of messages is normal and that 2k of them are encoded, then Fig 1 shows the improvement in transmiss-Jon for various values of dispersion and message length. These curves show that the impro-.-ement factor lies between 2 and 5. When plain text is transmitted, errors may be detected and corrected by comparison with the surrounding text. With a coded message however, quite meaningless groups are employed and other means are necessary to reveal errors. We will suppose -..hat Ila" letters are used to constrr-ct 'the groups. Then the general expression for a five-p,:~sition code in which all the combinations differ with one another by not less than two positions is given by Eq (18). Fig 2 shows how the vocabulary may be constructed for the case where a =-5. Three tables are constructed and connected together as shown and contain the symbols inserted from the formulae (21). (22) and (23). The ecded group (18) consists of Card 2/4 four imformation symbols and a control symbol. Suppose sov/lo6-39-3-8/12 The Theory of Telegram Coding by Means of Uniform Correcting Codes the information is 0113, the combination 01 is found in the second row of Table 1, while the combination 13 is found in the fifth column of Table III. These two lines intersect in Table II giving the control symbol 0. The construction of a code in which the groups differ by not less than three positions is undertaken with Eq (24) as a general expression (Fig 3 shows the tables for finding the control symbol). In modern telegraphic equipment a seven-unit code is employed of which five units may be used to carry information. The majority of the letters in the Russian alphabet may therefore be encoded. If the code system of Eq (24) is used then it is possible to both reveal and correct single errors. Suppose for example that the group 02132 was transmitted but that due to distortion was received as 04132. Then from the tables in Fig 3, it will be seen that if the first three letters are taken as 041 then the second two cannot be 03; this proves that the receiver is incorrect. To reveal the Card 3/4 error we work from the other end of the message. In sov/lo6-59-3-8/12 The Theory of Telegram Coding by Means of Uniform Correcting Codes Table III (Fig 3) we find the number of the row in which the combination 32 occurs; this is row 5. Along the same column in Table II (Fig 3) we find the third symbol as I (row Further in Table I (Fig 3) the intersection of row and column 5 gives 02. Since this combination (02) differs from the first two letters as received (04) in only one position, then we can conclude that the second letter as received is incorrect and that the true group should be 02132. There are 3 figures and 7 references, 5 of which are Soviet and 2 English. SUBMITTED: 1st November 1958 Card 4/4 Al 13 17 L C X- (CMA) t ~V~ 1k IL Uq~ JL IL MOM mul 4.

In particular a method is given for constructing equidistant codes in which the combinations differ from each other in exactly d positions-. To construct the codes, the mathematical apparatus of the theory of finite commutative groups is employed. kfter presenting the method for constructing the codesthe author analyses the probability of correct reception using the:equidistant codes and using an optimal self-correcting code not equidistant. It is Card shown that in certain systems for processing the codes 1/2 the probability of correct reception of a combination may be smaller for the code with greater dmin. This Wrly s/lo9/6o/oo5/o6/o0l/O2l B140/9163 Equidistant and Other Optimal and Near-Optimal Codes apparent paradox is due to the assumption of symbol-by- symbol reception of the code combinations,. However, using Wagner's (Ref 8) method such paradoxes will not arise. For maximum probability of correct reception it isnecessary to use modern atatistical methods of reception and codes constructed with regard to these Card methods and the properties of the given channel. 2/2 There are 3 tables:and 8 references~ of which 6 are Soviet and 2 English.

TITLE: Receiver With a "Floating", (Random) Threshold PERIODICAL: Elektrosvyazi, 1960, No. 12, pp. 61-68 TEXT: After recalling the importance of the noiseproof feature of communication systems using correcting codes, the author of the article pro- ceeds with a comprehensive analysis.of a nerrmethod of reception of correct- ing code combinations.. This method is based, as are the earlier~described methods, upon the knowledge of a posteriori probabilities~of the received symbols, but it also uses the following property of the correcting codes; The combinations, in these codes, are determinable,.by n1 < n.symbols (n be- ing the number of symbols in the.combination). The autAor's method-ensures a greater probability of correct reception of combinations. Indeed, the re- ceiver's 11deoision" as regards the transmitted communication is taken, every time, only according to r.1 4 n symbols of the received combination having the greatest a posteriori probabilities. This is why the author named his method: method of reception aooording to the most reliable symbols or method Card 1/4 L#," 20093 S11061601000101210061009 Receiver With a "Floating" (Random) Threshold. A055/AO33 of reception with a "floating" (random) threshold; (indeed, if the received symbols are numbered.in the order of their decreasing a posteriori probabili- ties, thus forming a kind of variational series, the random value of the ni-th member of the series conatitutes a threshold determining the n - nj symbols having no influenoe upon the lldecisionll)~ In*his comprehensive ana- lysis, the author first examines the general case, where the transmitted combination is determined by the-comparison of nj most reliable symbols with the-symbols of all the combinations of the code occupying the same n, posi- tions. In this case, the memory of the receiver must contain all the combi- nations of the code,; Therefore, the author then examines the case of cor- recting codes with control symbols, where reception according to his method can be achieved without the neoessity of "memorizing" all combinations. He also works out and analyzes formula allowing to calculate the probability of a correct reception. To prove the superiority of his method over other me- thods, particularly over the Wagner method (superiority from the point of view of the probability of a correct reception), the author resorts to a statistical experiment performed.with an electronic computer. The enclosed table, containing the results of this experiment, proves that the author's Card 2/4 e S/106/60/000/012/006/009 Receiver 'With a "Floating" (Random) Threshold A055/AO33 method, though inferior to ideal reiception, is superior,to-that of Wragner. Moreover, the Wagner method can apparently be applied only to binary codes, which is not the case.with the author's method. There are 1 table and 10 So- viet references.

P., Member of the Society (L/'V0R;'G) ---------------- TITLE: Ideal Identification Device for Compound PERIODICAL: Radiotekhnika, 1960, Vol. 15, No. 8, PP. 42-52 TEXT: In the present paper it is first shown that the method of symbol reception is no optimum method even if the receiving device has a receiver which, according to V. A. Kotellnikov (Ref. 1), is ideal. The block diagram used in this method is shown in Fig. 1. Figs. 2 and 3 show the block diagrams of reception devices by means of which ideal methods of identification may be realized. Besides, simpler though not ideal reception methods can be used for these block diagramsy e.g. Vagners method (Ref- 4), and the method of reception according to the most reliable symbols. An identification devj-.e is described which for a given receiver warrants the maximum probabilit- of correct reception of the correction code combinations. It is demon trated that the use of such an ideal device and of equidistant codes makes it possible to transmit the Card 1/2 82868 Ideal Identification Device for Compound S/108/60/015/008/005/006 Sin. als B012/3067 communications with required authenticity in the channel. The possibility of correcting the errors by mathematical operations is pointed out and illustrated by an example. In the present paper, the method described was compared with the method of symbol reception, Vagner's method. and the method of reception according to the most reliable symbols by means of a statistical experiment made on a high-speed electron computer. The results of these investigations are presented in Table 1. They show that the ideal identification device described is the best one as to error frequency, and that the method of symbol reception is worst. The author thanks V. I. Siforov, Corresponding Member AS USSR, for his interest shown in the paper, and Ye. P. Nesterova for having conducted the statistical experiment.

First,, the necessary and sufficient conditions for construction of the group code'(n,d), where n . m + k (m denoting the'number of in- formation~ digits, and k the number of checking digits), d - the num- ber o-1: posi-* tions, are ascertained.

TITLE: Rare earths in perovskites (knopites) from massifs of ultra- basic alkali rocks n PERIODICAM %Xeokhimiya, no. 4, 1960, 291-297 TEXT: In general,previous geochemical studies of rare earth elements were only concerned with individual rare-earth minerals. The present publication, however, deals with the rare-earth (RE) content of perovskites and knopites the variety richer in RE, from various rocks. The study aimed at estab- lishing the properties of perovskites as geochemical indicators of RE and other rare elements. The chemical composition of 13 perovskite samples from ultrabasic alkali rocks (Kareliya, Kol'skiy peninsula, Polar Siberia and Aldan) was determined. The samples were collected by L. S. Borodin. One sample was supplied by S. P. Stoyalov. R. L. Barinskiy determined the chemical composition X-ray spectroscopically in chemically separated RE precipitates. The chemical separation was carried out by Z. Katayeva, Card 1/5 S/007/60/000/004/001/005 Rare earths in perovskites... B002/BO55 T. A. Kapitonova and I. S. Razina, analysts of the IMGRE AN SSSR (Institute of Mineralogy, Geochemistryp and Crystallochemistry of Rare Elements, AS USSR). All the perovskite samples were found to contain relatively large amounts of cerium, lanthanum, neodymium and praseodymium, and very small quantities of yttrium earths. A plot of the total RE content (abscissa) against the relative content of individual RE (relative to IRE =100%) (ordinate) makes the following geochemical conclusions possible (Fig.1): The total RE content of perovskites and the concentrations of the individual RE elements are correlated. The relative contents of neodymium and praseodymium, i.e., the less basic elements, increase with decreasing age of the perovskite generations, whereas the lanthanum content decreases. The cerium content remains more or less constant (46-52% ofM). A sorrelation also exists between the relative contents of the individual elements and those of lanthanum (Fig. 2) and neo&ymium (Fig. 3). Altogether, the perovskites may be divided into two types: 1) perovskites with higher concentrations of basic elements, especially lanthanum. These perovskites come from olivinites, pyroxenites, melilitites and rocks containing perovskites of conveniional habit; 2) perovskites containing larger Card 2/5 S/007/60/000/004/001/005 B002/BO55 Rare earths in perovskites... quantities of the less basic lanthanides, generally termed knopites. The total RE- and niobium. contpnts of this type are high. From these results it is assumed that perovskites are of a hydrothermal-metasomatic origin. Mention is made of E. A. B gdasarov, Ye. M.

Voprosy mineralogli i geokhimii redkikh elementov. 3 - 25 TEXT.~ In contrast to procedures advocated by other workers% in this field, the present author used lanthanum graphs in his study of the nature of correlation associations in cerium- bearing minerals. Lanthanum was chosen as the reference element because of Its proximity to lanthanolds proper, and because, at the same time, it differs from other lanthanoids regarding those chemical properties which depend.directly on the basicity of the medium (thus, for instance, lanthanum is more basic than any of the other trivalent rare-earth elements and is charaf:~ter- ized by lowest stability of its complex compounds). Accordi,~g to Card 1/4 S/677/61/000/007/001/00*--) Correlation associations ocoo El93/E383 D.SXorzhinskiy, an increase in the basicity of magma and magmatic aqueous solutions brings about an increase in the activity of all bases (weak bases, in particular) which is reflected in the systematic-variation of the paragenetic ratios of minerals, sequence of crystallization processes and composition of minerals. Consequently, using lanthanum (the strongest base among lanthanoids) as an indicator of the basicity of the medium provided the most convenient means of elucidating the geochemical variations in the composition of the rare-earth group; particularly in essentially cerium minerals. Starting from these premises, the present author constructed a series of lanthanum graphs, i.e. graphs in which the concentration of varlous rare-earth elements is plotted against the lanthanum. content in the mineral. Grapbs of this type were constructed for perovskite, monozite, rinkolite, lovehorrite, ivudjavrite, sphene and apatite. In addition to,these graphs, data are given on the distribution of rare-earth elements in minerals in Khihiny and Ldvozero massives, and lanthanum graphs are reproduced for these minerals which include eudialyte, rinkolite, Car-d 2/4 s/677/61/000/007/001/003 Correlation associations 9 ... E193/E383 sphene, apptite, loparite, apophyllite and steenstrupine. The geochemistry of the minerals studied is discussed in the light of both these data and views expressed by other workers. Among other points made in the concluding paragnphs. it is stated that comparison of the composition of the minerals of various origins with which the present work is concerned - indicates that in the case of solutions with a "complex" content of rare-earth elements which, at the same time, are characterized by high chemical activity of the most strongly basic elements (lanthanum and cerium, in partlcular),~no separation of the rare-earth into two groups (cerium and yttrium groups), each containing approximately-an equal number of elements, takes place. Under these conditions, selective separation is possible as well as the appearance of par excellence rare-earth, essentially cerium-bearing minerals. There is a close relation- ship between these processes which depend on specific conditions of fractional crystallization, particularly on the basicity of the medium. For this reason, the rare-earth elements content of minerals (including complex minerals) cannot be identified Card 3A S/677/61/000/007/001/003 Correlation associations ....
