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 ...

Recent developments in empirical dynamic modelling

open access: yesMethods in Ecology and Evolution, 2022
Ecosystems are complex and sparsely observed making inference and prediction challenging. Empirical dynamic modelling (EDM) circumvents the need for a parametric model and complete observations of all system variables.

Dynamic modelling and vibration suppression of a single-link flexible manipulator with two cables

open access: yesMechanism and Machine Theory, 2021
This paper introduces the dynamic modelling of a single-link flexible manipulator with two cables. The end-effector is attached at the distal end of the flexible link and tensed cables are used to suppress vibration. The flexible link is considered as an

Dynamic Modeling and Control of a Parallel Mechanism Used in the Propulsion System of a Biomimetic Underwater Vehicle

open access: yesApplied Sciences, 2021
Incorporation of parallel mechanisms inside propulsion systems in biomimetic autonomous underwater vehicles (BAUVs) is a novel approach for motion generation.

A Dynamic Model of Predation

open access: yesSSRN Electronic Journal, 2022
ABSTRACT We study the feasibility and profitability of predation in a dynamic environment, using a parsimonious infinite‐horizon, complete information setting in which an incumbent repeatedly faces potential entry. When a rival enters, the incumbent chooses whether to accommodate or predate it; the entrant then decides whether to stay

Modelling and Stabilisation of an Unconventional Airship: A Polytopic Approach

open access: yesAerospace, 2022
The paper presents the modelling and stabilisation of an unconventional airship. The complexity of such a new design requires both proper dynamic modelling and control. A complete dynamic model is built here.

A novel method for building air conditioning energy saving potential pre-estimation based on thermodynamic perfection index for space cooling

open access: yesJournal of Asian Architecture and Building Engineering, 2023
The construction energy consumption (CEC) is about 35% of entire energy consumption (EC), of which 50% is for cooler air-conditioner. The practical cooling EC is relevant to the dynamic thermal performance of cooler air-conditioner.

Model for macroevolutionary dynamics [PDF]

open access: yesProceedings of the National Academy of Sciences, 2013
Significance Genera are often viewed as artificial constructs of taxonomic practice. Here, we show that a stochastic model that includes three events with constant rates—species formation, extinction of species, and origination of new genera—can describe well the species-within-genus distributions for large taxa.

Dynamic delta modeling [PDF]

open access: yesProceedings of the 16th International Software Product Line Conference - Volume 2, 2012
Abstract Delta Modeling (ADM) offers an algebraic description of how a (software) product line may be built so that every product can be automatically derived by structured reuse of code. In traditional application engineering a single valid feature configuration is chosen, which does not change during the lifetime of the product.

Techno-economic potential of battery energy storage systems in frequency response and balancing mechanism actions

open access: yesThe Journal of Engineering, 2020
Batteries offer a combination of balancing and regulation services within a smart grid to improve its resilience and flexibility. Maintaining an acceptable state of health and the highest rate of return requires dynamic modelling of the asset and ...
