The V.M. Glushkov Institute of Cybernetics is one of three institutes that form the Cybernetical Center. It is the largest of the three, employing approximately 2,000 scientists and support personnel. The Institute of Mathematical Machines and Systems has 1,800 personnel while the Institute of Programming Systems has 400 personnel. The research at the Institute of Cybernetics has four major directions:
For the WTEC visit, short presentations were made by department heads and laboratory directors, who were responsible for research that could be related to the science and technologies of advanced electronic displays. The highlights of the presentations are summarized.
Laser research included development of new materials with gallium-arsenide and indium-gallium-arsenide mentioned specifically, development of lasers up to 10 GHz, improvement of optical fiber and fiber-optic systems. There is some work in this section also on light-emitting diodes.
The head of the Department of Cryoelectronic Devices reported that his department had a high level of expertise in superconducting materials at both low and high temperatures. These scientists had developed superconducting devices and circuits, such as a superconducting chip for an antenna. Research had led to practical development of a system for accurate deposition of thin films. Uniform films in the 1-2 nm range were cited for aluminum oxide. The system of controlling very thin film through the use of anodization spectroscopy was described as less expensive and better than any other known (i.e., specifically better than surface sputtering). The process has been useful in controlling thin-film structures that are based on metals tending themselves to anodic oxidation such as Nb and Al in the case of Nb/AlOx-Al/Nb Josephson junctions. The method makes it possible to obtain information about layer thickness and continuity, interface sharpness, and surface smoothness, and gives high resolution with respect to layer depth (about 0.5 nm). Additional information about porosity and contamination are possible.
The department had also developed special circuits for mapping weak magnetic fields that may be particularly useful for biomedical instrumentation. In fact the department had equipment that could be used to measure the level of iron in human organs to determine possible environmental pollution effects.
One laboratory section claimed an original Ukrainian process for designing passive matrix LCD displays so that levels of gray could be determined by a purely digital method. The same section was doing active matrix research on MDM and MIM to reduce manufacturing costs, and to achieve low-voltage operation (5 V) and improved resistance parameters.
Some research has been done with time modulation of electron beams for energizing thermoplastics or CTS ceramics. Special electronic beams and displays have been built. But currently only low resolution that approximates a television has been achieved, with poor color and large power consumption.
In conjunction with the Erotron company of L'viv (Lvov), large modular rear projection displays have been developed. Each module is 100 cm x 80 cm. The modules can be assembled tightly in 4 x 4 or larger arrangement with no visually perceivable discontinuities at module boundaries. Software has been developed to couple the large display with a group decision support system (GDSS), in which individual workstations can use a mouse to grab objects or portions of the 16- module display for local work. The software for the large screen runs under UNIX on an IBM 486 PC.
Professor T.K. Vintsiuk discussed work in computer voice input/output, and gave a tour of his laboratory. Since 1966 he has been researching automated speech recognition using an "ACDP" approach that involves stochastically generated grammars and dynamic programming techniques. In the tour of his laboratory, he demonstrated speech recognizers, speech synthesizers, automated translators, and speech analysis equipment. The equipment had been produced in his laboratory, which was generally well-equipped and supported by several staff. A system for real-time translation with speech input in one language and spoken output translated to another language was impressive. The equipment could be purchased in the future from the institute, but prices were not yet available.
The Institute of Cybernetics in Kyyiv has modern facilities and has been supporting first class scientific research and excellent technical design work. Professor Palagin expressed the institute's desire for collaborative ventures for industry or research and development. The work in the Department of Cryoelectronic Devices for accurate control of thin film, and the work on digital control of gray scale, as well as many other areas, are candidates for cooperative development that may lead to improvements in processes for LCD manufacturing.
