The subject of study is the physical processes of translational and angular motion of a two-wheeled experimental sample. The goal is to develop physical, mathematical, and graphic models of the translational and angular ...
Performance evaluation of various deployment scenarios of the 3-replicated cassandra NoSQL cluster on AWS
(ХАІ, 2021)
A concept of distributed replicated NoSQL data storages Cassandra-like, HBase, MongoDB has been proposed to effectively manage Big Data set whose volume, velocity and variability are difficult to deal with by using the ...
Simulation and forecasting of the influenza epidemic process using seasonal autoregressive integrated moving average model
(ХАІ, 2021)
The study aims to develop a seasonal autoregressive integrated moving average (SARIMA) model for influenza epidemic process simulation and to investigate the experimental results of the simulation. The work is targeted at ...
Application of dynamic programming approach to computation of atomic functions
(ХАІ, 2021)
The special class of atomic functions is considered. The functions considered are used in discrete atomic compression (DAC) of digital images. The algorithm DAC is lossy and provides better compression than JPEG, which is ...
