Mathematical modeling of hydraulic chains as cyber-physical objects [PDF]

open access: yesE3S Web of Conferences, 2020
The article attempts to substantiate a new direction of scientific research of pipeline systems (PLS) of the energy sector as cyber-physical objects. The relevance of this direction is determined by the practical formation of new properties of PLSs in ...

Unification theory of optimal life histories and linear demographic models in internal stochasticity. [PDF]

open access: yesPLoS ONE, 2014
Life history of organisms is exposed to uncertainty generated by internal and external stochasticities. Internal stochasticity is generated by the randomness in each individual life history, such as randomness in food intake, genetic character and size ...

Combined system of extreme control of mineralized water dilution in river basins

open access: yesМеліорація і водне господарство, 2021
The theory of combined systems of extreme control, which is used in technical systems, was developed and adapted in socio-ecological-economic systems. For example, river basins are such systems.

An Efficient Stochastic Linearisation Procedure for the Seismic Optimal Design of Passive Control Devices

open access: yesFrontiers in Built Environment, 2020
The seismic response of structures is often enhanced by introducing passive control devices that can operate through the dissipation of the input energy or by modifying the dynamic characteristics of the main structure.

Inventory management via model predictive control based on demand forecast considering price change by particle filter

open access: yesNihon Kikai Gakkai ronbunshu, 2018
It is important to manage inventory adequately at a retail stores or wholesales. For this reason, we propose an inventory management method based on model predictive control.
