Levan Gvaramadze 1968 After graduating from the Georgian Polytechnic Institute, he studied for a postgraduate degree at the A. Eliashvili Institute of Management Systems of the Georgian Academy of Sciences. And in the following years, he worked at the institute as a junior researcher, group leader, laboratory leader, senior researcher, researcher. Over the years his scientific interests have been the problems of scientific research automation, the use of databases for storing and managing information flows, the design of technical automated control systems and their components, the use of programming technologies for the design of systems.

The comparative classification for interfaces connecting information blocks and a central computer and taking into account the bandwidth, electrical connection, and software implementation features is proposed. The proposed approach is realized on the example of choosing the information structure of the two-channel quasi-homogeneous automated system for supporting a thermophysical experiment.	https://gtu.ge/msi/Files/Pdf/2Contents_PCPE_2004.pdf

Tbilisi, Georgia.	2010	1/11/2010-4 /11/2010	Georgian Technical University	Adaptive control of artificial microclimate	oral	The article discusses the artificial microclimate adaptive control method, providing enhancing control functionalities, reducing energy costs, and increasing the accuracy of maintaining critical microclimate parameters at predetermined levels. Constructing principles, structure, and peculiarities of functioning of two (control and regulation) subsystems of the adaptive control and regulation system for artificial microclimate parameters are given. The subsystem of the processed system consists of DV2TS-IT-IP-A-III type n converter of temperature and turbulence, 6-15 volt power supply, mains connection channel, TCC-1001 adapter, converting RS-232 interface to RS-422/485 interface, and personal computer. The control subsystem includes a personal computer, an LPT adapter connected to its parallel port, D-decoders, control blocks, temperature and humidity control devices, and a control bus. The article describes the structure and operating principles of the software module for the control subsystem.	https://institutes.gtu.ge/uploads/ფრანგიშვილი 80 წ. კონფერენცია 2010.pdf

Possible development trends of such calibrators are indicated. The disadvantages connected to using modern calibrators are also highlighted. The possible method providing dynamical compensation for unwanted changes in the output characteristic of the device caused by outrageous impacts acting on the system (changes in load resistance, mains voltage, frequency, ambient temperature, etc.) is proposed. The block diagram of the calibrator using this method is given.	https://gtu.ge/pdf/kon/konf_energetikis_tanamedrove.pdf
