Examples of National Projects

  1. Methods and technologies of modelling, verification and implementation of computer systems with concurrent data processing (2006-2011).
  2. Development and implementation of intelligent technologies for microwire parameters measurement and casting process control (2008-2009).

The main objective of the project was the development of the intelligent measurement techniques of the microwire parameters in a dynamic mode and in the control of the casting process. The goal of the project was to increase the quality of the microwire and the labour productivity of the operators. Work included designing and building an advanced system for measuring wire parameters, development of algorithms for on-line image processing of the droplet and building the mathematical model of the droplet. A three-dimensional model of the microwire casting with insulated glass was also produced.

  1. Methods and advanced technology design and development of reconfigurable computing applications (2011-2014).

The research carried out within the project enabled automation of the design and implementation of a specialized processor with real-time reconfigurable architecture based on FPGA circuits. To achieve this goal, a method of synthesis of control systems (specialized processors) with reconfigurable architecture based on the implementation of the Hardware Petri Net (HPN) model working with FPGA circuits was proposed and developed. For the specification and modelling of the specialized processor, a synchronous reconfigurable temporised HPN was developed which enabled using the design of the logical description of the computer system architecture for the direct implementation of the HPN model in the reconfigurable hardware architecture. The proposed method, based on the direct mapping of the Petri net models (HPN) into reconfigurable circuits, enables reduced algorithmic complexity and a transparent correspondence between the elements of the initial specification and the components of the resulting circuit.

  1. Models, methods and interfaces for the management and optimization of intelligent manufacturing systems (2015-2019)

The objective of the project was the development of new models and methods that can contribute to intelligent products design. The following scientific results were obtained within the project:
