The monitoring of a structure (e.g., a building) enables safe utilization of such a structure. A large number of sensors that measure selected parameters are often required in applied monitoring systems. Cables or batteries are used to power such sensors.... see more

Simple harmonic motion is motion back and forth regularly through an equilibrium point with the number of vibrations in every second always the same or constant. This experiment focuses on one example of an elastic object, namely a spring. The response of... see more

The analysis of processes occurring in the medium under the influence of vibrational forces is considered. The obtained results are synthesized for the development of a new class of vibration machines that provide criteria for efficiency and reliability. ... see more

The analysis of processes occurring in the medium under the influence of vibrational forces is considered. The obtained results are synthesized for the development of a new class of vibration machines that provide criteria for efficiency and reliability. ... see more

In this paper, the basic principle and characteristics of a phase-locked loop (PLL) in a single phase grid-connected system are analyzed, and this paper introduces one type virtual orthogonal voltage vector method based on a third order generalized integr... see more

In order to study switching transients in an offshore wind farm (OWF) collector system, we employ modeling methods of the main components in OWFs, including vacuum circuit breakers (VCBs), submarine cables, and wind turbine transformers (WTTs). In particu... see more

It is known a priori that vibrations that occur in the elements of the track structure during the passage of a train load are a superposition of free and forced mechanical vibrations. It has been established that the range of oscillation frequencies of th... see more

Combustion instability in rocket engines is accompanied by large-amplitude pressure fluctuations in the combustion chamber and (or) intense vibration of the load-bearing structural elements. Unstable operation leads to a decrease in thrust, specific impul... see more

During November 2017, an active source seismic survey was performed in Andaman sea to study the acoustic propagation characteristics. High power low frequency acoustic signals generated by 20-air gun array onboard ORV Samudra Ratnagar were recorded from I... see more
