Entropy in Hydrology

open access: yesPerspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract Although the concept of thermodynamic entropy due to Clausius dates back to the early 1850s, the mathematical theory of informational entropy was not developed until the pioneering work of Shannon in 1948, the development of principle of maximum entropy (POME) and theorem of concentration by Jaynes in 1957, principle of minimum cross entropy ...

The Discrete–Continuous Correspondence for Frequency-Limited Arma Models and the Hazards of Oversampling [PDF]

open access: yes
Discrete-time ARMA processes can be placed in a one-to-one correspondence with a set of continuous-time processes that are bounded in frequency by the Nyquist value of ? radians per sample period.

Comparative analysis of frequency characteristics for constructing digital models options of components of electrical complexes aperiodic units

open access: yesИзвестия Томского политехнического университета: Промышленная кибернетика
Meeting the ever-increasing requirements for sensorless electric drives from technological processes can be achieved through the use of digital twins, which are a digital (discrete) model of a dynamic system.

Dynamic Identification of a Lightly Damped Slender Structure Using Compressive Sensing

open access: yesIEEE Access
A great deal of signals coming from structural monitoring scenarios are sparse in the frequency domain, suggesting the application of Compressive Sensing (CS) techniques in order to reduce the quantity of transmitted information.
