On classifier learning methodologies with application to compressed remote sensing images
(ХАІ, 2022)
Remote sensing images have found numerous applications nowadays. A traditional outcome or intermediate result of their processing is a classification map. Such maps are usually obtained from a pre-trained classifier and ...
Theoretical and experimental study of performance anomaly in multi-rate IEEE802.11ac wireless networks
(ХАІ, 2022)
The paper comprehensively investigates the performance anomaly occurring in wireless networks with subscribers at different data rates using three approaches: experimental measurement, analytical study, and simulation ...

(ХАІ, 2022)
The subject of study is the Green's functions of the first and second boundary value problems for the Laplace equation. The study constructs the Green's functions of the first and second boundary value problems for the ...
On strange images with application to lossy image compression
(ХАІ, 2022)
The task of the article is to provide a definition of strange images and check whether the non-monotonicity of the dependences of the distortions on the compression level holds for different encoders and metrics. Another ...
Method of QOS evaluation of FPGA as a service
(ХАІ, 2022)
The subject of study in this article is the evaluation of the performance issues of cloud services implemented using FPGA technology. The goal is to improve the performance of cloud services built on top of multiple FPGA ...
Predictive model of COVID-19 epidemic process based on neural network
(ХАІ, 2022)
The purpose of the research is to build a model of the epidemic process of COVID-19 to predict its dynamics based on neural networks. The object of research is the epidemic process of infectious diseases using the example ...
Aircrafts control rational intellectualization
(ХАІ, 2016)
Features of flying vehicles that are functioning under destabilizing influence are reviewed. Basic aspects of the
rational control in presence of uncertainty are introduced through the proposed principle of control on ...
Time-frequency representation enhancement: approach based on image filtering methods
(ХАІ, 2016)
The task of filtering of the time-frequency representations, obtained by the S-method, using advanced digital image processing filters, both local and nonlocal is considered.
Prediction of compression ratio for ADCT coder
(ХАІ, 2016)
One way to predict compression ratio for efficient coder called ADCT is proposed. Prediction is based on determination
of a simple parameter before compression that can be easily calculated in 8x8 pixel blocks. Such ...
