It is shown that the frequo 'ncy of spin resonance is displaced to
higher values for magnetized samples. The permeability jill is ''I Xf
lower at 980 Mc/s than at 285 Mc/s and fall's off in the presence
of a d.c. magnetic field 4p to + 20 Oe). In addition, there is
a'marked dependence of relonant Trequency on,~emperature, e.g.
11.00 and 65.0 Mc/s at 20 apTi 6010C, respectively. The fi-equency
dependence of 1,L1 and III' is investigated for quenched samples

3 000 Mc/s). Resonant frequencies calculated from this data have
Yalues of 540 Mc/s for annealed samples and 180 'Mc/s for enched
qu
samples, compared with corresponding observed values of 1100 and
58 o~-61,o mc/s (for different samples). The results are discussed

ABSTRACT: The authors propose a universal device for the study of image-recogni-
tion algorithms. the purpose of which Is to Introduce information regarding a
graphic image (drawing, plan. etc.) into.a computer., The device is controlled,bi.!
f
the computer, a fact whichmakes It possible.to-simulate any kind of scanningo
a drawing executedwith India Ink, printer's Ink or pencil on paper. in this case,',,:
there is no need to transfer the drawing to the memory of the computer; ieee, to
burden the memory with unprocessed information, since it Is possible to refer to
any point of the drawing at the necessary moment. The device Is capable of dis-
iinguishing 16 gradations of grayness. thus'making It possible to process not only;i
arl2edrawings. but-half-tone work as well. TheInstrument Is designed to be used

ABSTRACT: An automatic picture reade ye briefly described in which the. scannifig
process is p rogram- controlled, J. e. , the.computer draws information about, any spot
of the picture whose coordinates the computer specifies. In this system. the picture
proper. serves as a storage of information, thus relieving the computer storage of the
bulk of its load. No intermediate information carrier (tape, punch card) is used.
Academician.V. M. Glushkov is credited with originating the idea- of such a universal.
apparatus ("Principles of synthesizing self-learning systems$ Gostekhizdat UkrSSR,
Kiev,: 1962). A block diagram of the apparatus is shown and its operation is
