The cavitation phenomena cause noise, vibration and instability in centrifugal pumps. Furthermore, the cavitation usually generates wear and material erosion of the rotor blades which decreases the hydraulic performance and the pump life. In this work, it... see more

Mathematical expressions, which are regular deterministic rules for synthesis of generalized binary Barker binary sequences, were proposed in the scientific literature. Sequences, which can be synthesized within the framework of these mathematical express... see more

Currently, a wide class of modern wireless telecommunications systems is based on the use of broadband signals. The problems of synthesis for their formation and processing algorithm are extremely important for such systems, especially under the condition... see more

In clause the algorithm of digital processing of an identification fragment of speech allowing is considered, on the basis of the analysis deviation of carrying frequency of a speech signal submitted as a signal with phase modulation, to increase accuracy... see more

Background: Epilepsy is a severe disorder of the central nervous system that predisposes the person to recurrent seizures. Fifty million people worldwide suffer from epilepsy; after Alzheimer’s and stroke, it is the third widespread nervous diso... see more

A new screening technique for obstructive sleep apnea (OSA) is implemented. This technique is based on finding the statistical signal characterization (SSC) parameters of the spectrum of pre-processed R-R-interval (RRI) data. A single classification facto... see more

The problem of selection of electroencephalographic rhythms and epileptiform activity search was investigated. The object of study is theprocess of extracting the EEG phenomena. The subject of study is time-frequency analysis methods of EEG signals. The p... see more

With modern production, Minimum Quantity Lubricant (MQL) technology has emerged as an alternative to conventional liquid cooling. The MQLs is an environmentally friendly lubricant method with low cost while meeting the requirements of machining conditions... see more

Slagging on boiler surfaces in power plants is still a serious problem to reduce thermodynamic efficiency and threaten the operation of generating units. In this study, an innovative slagging diagnosis method based on analysis of vibration signals from tu... see more
