Dynamic model of a harvester equipped with a rope anchor system during logging operations on a steep slope [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета
The efficiency of using logging machines for work in mountainous or hilly areas characterized by the presence of steep slopes depends on many factors, among which the quantitative parameters of the dynamic state of both the harvester itself and the ...

Numerical simulation of dynamic processes during operation of emergency brake of tunnel escalators [PDF]

open access: yesНаучно-технический вестник Брянского государственного университета
The emergency brake is an essential element of the escalator safety system, designed to prevent the negative consequences of emergency situations. However, due to the very rare operation of this mechanism, the effect of dynamic loads on its elements has ...

Dynamic causal modelling

open access: yesNeuroImage, 2003
In this paper we present an approach to the identification of nonlinear input-state-output systems. By using a bilinear approximation to the dynamics of interactions among states, the parameters of the implicit causal model reduce to three sets. These comprise (1) parameters that mediate the influence of extrinsic inputs on the states, (2) parameters ...

Nonparametric dynamic modeling [PDF]

open access: yesMathematical Biosciences, 2017
Challenging as it typically is, the estimation of parameter values seems to be an unavoidable step in the design and implementation of any dynamic model. Here, we demonstrate that it is possible to set up, diagnose, and simulate dynamic models without the need to estimate parameter values, if the situation is favorable.

Entrepreneurial ecosystems: a dynamic lifecycle model [PDF]

open access: yes, 2019
The concept of entrepreneurial ecosystems has been used as a framework to explain entrepreneurial activities within regions and industrial sectors. Despite the usefulness of this approach, the concept is under-theorized, especially with regard to the ...

Dynamic Modeling and Control of BDFRG under Unbalanced Grid Conditions

open access: yesEnergies, 2021
The Brushless Doubly-Fed Reluctance Generator (BDFRG) is a potential alternative to the Doubly Fed Induction Generator (DFIG) in wind power applications owing to its reasonable cost, competitive performance, and high reliability.

Design of Wave Glider Optimal Parameters Suitable for the Northwest Pacific Ocean, the North Indian Ocean, and the South China Sea

open access: yesJournal of Marine Science and Engineering, 2021
To study the optimal design of Wave Glider parameters in the wave environment of the Northwest Pacific Ocean, the North Indian Ocean, and the South China Sea, the average velocity of a Wave Glider was taken as the evaluation criterion.
