THE USE OF PARABOLIC SPLINEES IN CAD OF LINEAR STRUCTURES

open access: yesРоссийский технологический журнал, 2018
The article continues studying the problem of the calculus of variations that occurs in line structures routing, in particular, roads. The task is to find a line that satisfies all technical constraints and gives a minimum of a given functional, for ...

Information and entropy theory for the sustainability of coupled human and natural systems

open access: yesEcology and Society, 2014
For coupled human and natural systems (CHANS), sustainability can be defined operationally as a feasible, desirable set of flows (material, currency, information, energy, individuals, etc.) that can be maintained despite internal changes and changes in ...

Trophic interactions and feedbacks maintain intact and degraded states of Hawaiian tropical forests

open access: yesEcosphere, 2022
Feedbacks within ecosystems can lead to internal reinforcement of the current state providing ecosystem resilience. Often, multiple biotic interactions across trophic levels play a role in such feedbacks, yet these are generally studied independently ...

Feedbacks between protistan single-cell activity and bacterial physiological structure reinforce the predator/prey link in microbial foodwebs

open access: yesFrontiers in Microbiology, 2014
The trophic interactions between bacteria and their main predators, the heterotrophic nanoflagellates (HNF), play a key role in the structuring and functioning of aquatic microbial food webs.
