Paper presents the description of research on two - phase gas - liquid flows. The research was inspired by the necessity of developing a new method for recognition of tested flows. In the beginning, there is a presentation of two - phase gas - liquid flows and special hydraulic installation where flows are created, next there is a description of the computer vision system which was created to research...
Regular granulation of fine materials requires appropriate density and humidity fluctuations. The control system of pelletizing process that assures optimal modes was proposed. The combined control algorithm was realized with fuzzy model based disturbance-stimulated control at the upper level, and the deviation control at the lower level.
In the article a method of parametric diagnostics of a gas turbine, based on fuzzy logic is proposed. The diagnostic map of interconnection between some parts of turbine and changes of corresponding parameters has been developed. Also we have created model to define the efficiency of the compressor using fuzzy logic algorithms.
Recent research has shown that work stress has become a widespread concern in Australia and other countries. It is a growing concern across all employment sectors as well as occupational levels and reported as a common cause of occupational illness. Work stress can be prevented if it is identified, measured and changes are made to the work environment. Multi-Agent technology has been used in many...
Prezentowany artykuł przedstawia wyniki prac nad systemem automatycznego rozpoznawania przepływów dwufazowych gaz-ciecz w rurociągach poziomych i pionowych. Opiera się on na logice rozmytej przy ocenie obrazów przestrzennych z tomografii 3D a następnie na przyporządkowaniu uzyskanych ocen do jednej z klas przepływu.
In this article the motion control system of autonomous mobile robot is described. Four motion modes: motion mode “to the target”, motion mode “obstacles avoidance”, motion mode “along the right wall” and motion mode “along the left wall” are implemented. A method for determining the effective rotation angle of mobile robot which is a linear combination of rotation angles which are obtained in different...

In this paper the new intelligent system for two-phase flows diagnosis and control is presented. The authors developed a fuzzy inference system for two phase flows recognition based on the raw 3D ECT data statistical analysis and fuzzy classification which identify the flow structure in real-time mode. The non-invasive three-dimensional monitoring is possible to conduct even in non-transparent and...
In this paper, the conceptual model of risk-based cost estimation for completing tasks within supply chain is presented. This model is a hybrid. Its main unit is based on Monte Carlo Simulation (MCS). Due to the fact that the important and difficult to evaluate input information is vector of risk-occur probabilities the use of artificial intelligence method was proposed. The model assumes the use...
The paper deals with the problem of works transport organization in logistic center with the use of artificial intelligence algorithms. The presented approach is based on non-changeable path during travel along a given loop. The ordered set of containers requesting transport service was determined by fuzzy logic, while the sequence of containers in a loop was optimized by genetic algorithms. A solution...
The paper discusses the details of modeling of the routing process according to the loading of output buffer storage. Shows the obtained dependence of the fraction of lost packets from the input intensity. It is shown that taking into account buffer occupancy increases the efficiency of their use and can significantly affect the quality of the functioning of the telecommunications network in the face...
Nowadays, with the rapid development of network technologies and with global informatization of society problems come to the fore ensuring a high level of information system security. With the increase in the number of computer security incidents, intrusion detection systems (IDS) started to be developed rapidly.Nowadays the intrusion detection systems usually represent software or hardware-software...
Process of eye tomogram obtaining by means of optical coherent tomography is studied.Stages of idiopathic macula holes formation in the process of eye grounds diagnostics are considered. Main stages of retina pathology progression are determined: Fuzzy logic units for obtaining reliable conclusions regarding the result of diagnosis are developed. By the results of theoretical and practical research...
The adaptation of the Ukrainian economy to the requirements of the European Union requires increasing the effectiveness of the system of making public management decisions regarding the development and assessment of the labor potential of our country. Currently, a unified system of evaluation indicators of the labor potential of Ukraine has not yet been developed. The authors substantiated and systematized...
The widespread use of computer technology, its rapid development and use in almost all areas of human activity requires constant updatingof information security issues. The activities of many enterprises in the field of IT, construction, and other areas are of a project nature and therefore further research on information security management of projects is relevant. Appearance of changes and the current...
The accident at the Chornobyl Nuclear Power Plant (ChNPP) in Ukraine in 1986 became one of the largest technological disasters in human history. During the accident cleanup, a special protective structure called the Shelter Object was built to isolate the destroyed reactor from the environment. However, the planned operational lifespan of the Shelter Object was only 30 years. Therefore, with the assistance...
