Model of Earth charge resonant oscillations excitations based on Tesla experiment, was offered. Solutions of d'Alembert wave equations for electric and magnetic potentials of the charged perfectly conductive sphere were found. Graphic analyses of perturbe... see more

Since the 1950’s-1960’s a large portion of Argentina has experienced a long period of high precipitation with important changes a 30-year period annual averages. Opposite conditions have taken place throughout the twentieth century in a l... see more

A Wide Area Measurement System (WAMS) can extend and effectively improve a controllers’capability of damping inter-area low-frequency oscillations in interconnected power systems. Thispaper presents an implementation of a Wide Area Fractional-Order Propor... see more

This paper describes a frequency domain approach for evaluating the impact of tower shadow and wind shear effects (TSWS) on tie-line power oscillations. A simplified frequency domain model of an interconnected power system with a wind farm is developed. T... 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

Resting-state functional magnetic resonance imaging was utilized to measure the amplitude low frequency fluctuations (ALFF) in human subjects with Alzheimer’s disease (AD) and normal control (NC). Two specific frequency bands (Slow5: 0.01-0.027Hz and Slow... see more
