Conservation planning integrating natural disturbances: Estimating minimum reserve sizes for an insect disturbance in the boreal forest of eastern Canada.

PLoS ONE, 2022
Large natural disturbances such as insect outbreaks and fire are important processes for biodiversity in forest landscapes. However, few methods exist for incorporating natural disturbances into conservation planning. Intact forest landscapes, such as in

Failure and instability mechanism of anchored surrounding rock for deep chamber group with super-large section under dynamic disturbances

Rock and Soil Mechanics, 2021
The interaction of super-large section chamber group in deep and close-distance condition will lead to stress concentration and wide failure range of surrounding rock, especially under dynamic disturbances.

Development and application of multifunctional shear test apparatus for rock discontinuity under dynamic disturbance loading

Rock and Soil Mechanics, 2022
Dynamic disturbance is an important influence factor that causes the sliding instability of rock discontinuity and then triggers strong dynamic geological disasters, such as earthquakes and rock bursts.

Time-dependent deformation characteristics of red sandstone under multiple dynamic disturbances

Yantu gongcheng xuebao, 2022
In order to explore the time-dependent deformation characteristics of deep engineering rock mass under disturbed action, the dynamic disturbance triaxial loading tests on red sandstone are carried out by using the disturbed servo triaxial loading system.

Extended dynamics observer for linear systems with disturbance

European Journal of Control, 2023
This is the last part of four series papers, aiming at stabilization for signal-input-signaloutput (SISO) linear finite-dimensional systems corrupted by general input disturbances. A new observer, referred to as Extended Dynamics Observer (EDO), is proposed to estimate both the state and disturbance simultaneously. The working mechanism of EDO consists

A theory of pulse dynamics and disturbance in ecology [PDF]

Ecology, 2019
AbstractWe propose four postulates as the minimum set of logical propositions necessary for a theory of pulse dynamics and disturbance in ecosystems: (1) resource dynamics characterizes the magnitude, rate, and duration of resource change caused by pulse events, including the continuing changes in resources that are the result of abiotic and biotic ...

Habitat-mediated facilitation and counteracting ecosystem engineering interactively influence ecosystem responses to disturbance [PDF]

, 2011
Recovery of an ecosystem following disturbance can be severely hampered or even shift altogether when a point disturbance exceeds a certain spatial threshold. Such scale-dependent dynamics may be caused by preemptive competition, but may also result from

Development of a knowledge model for managing schedule disturbance in steel-making [PDF]

, 2004
The development of a knowledge model, which describes the reasoning process in managing schedule disturbance in steel-making, is presented. A literature review shows the lack of research in developing a knowledge model for decision-making in steel-making.

Non-dynamism and temporal disturbances

Synthese, 2023
AbstractPhilosophical accounts denying that temporal passage is an objective feature of reality face an explanatory challenge with respect to why it appears to us as though time passes. Recently, two solutions have surfaced. Cognitive illusionism claims that people experience the passage of time due to their belief that time passes.
