Evaluation of linear and non-linear activation dynamics models for insect muscle.

PLoS Computational Biology, 2019
In computational modelling of sensory-motor control, the dynamics of muscle contraction is an important determinant of movement timing and joint stiffness. This is particularly so in animals with many slow muscles, as is the case in insects-many of which

Analysis of parametric biological models with non-linear dynamics [PDF]

Electronic Proceedings in Theoretical Computer Science, 2012
In this paper we present recent results on parametric analysis of biological models. The underlying method is based on the algorithms for computing trajectory sets of hybrid systems with polynomial dynamics. The method is then applied to two case studies

A Non-linear Viscoelastic Model of the Incudostapedial Joint [PDF]

Journal of the Association for Research in Otolaryngology, 2019
The ossicular joints of the middle ear can significantly affect middle-ear function, particularly under conditions such as high-intensity sound pressures or high quasi-static pressures. Experimental investigations of the mechanical behaviour of the human incudostapedial joint have shown strong non-linearity and asymmetry in tension and compression ...

A new Bayesian approach to the Toler model for evaluating the adaptability and stability of genotypes

Crop Breeding and Applied Biotechnology, 2023
This study aimed to apply, in unprecedented depth, a Bayesian approach to the non-linear regression model developed by Toler for evaluating the stability and adaptability of genotypes.

Driver Estimation in Non-Linear Autoregressive Models [PDF]

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
In non-linear autoregressive models, the time dependency of coefficients is often driven by a particular time-series which is not given and thus has to be estimated from the data. To allow model evaluation on a validation set, we describe a parametric approach for such driver estimation.

Comparison Between Phenomenological and Fiber-Section Non-linear Models

Frontiers in Built Environment, 2020
The prediction of the seismic response of structures requires accurate models for describing the behavior of each structural element. In frame analysis, non-linearities are typically modeled through either lumped or distributed plasticity elements ...

Non-Linear Models for Assessing Soil Moisture Estimation

Horticulturae
Accurately estimating soil moisture (SM) without direct measurements poses significant challenges due to nonlinear interactions in meteorological variables and the lagged response of SM to precipitation.

Using quantile regression methodology to evaluate changes in the shape of growth curves in pigs selected for increased feed efficiency based on residual feed intake

Animal, 2019
Growth rate is a major component of feed efficiency when estimating residual feed intake (RFI). Quantile regression (QR) methodology can be used to identify animals with different growth trajectories.

Short-Term Load Foresting Using Combination of Linear and Non-Linear Models

IEEE Access
Numerous short-term load forecasting models are available in the literature. However, the improvement in forecast accuracy using the combination models has yet to be analyzed on a daily rolling basis for a very long test period.
