Intelligent Flow Friction Estimation. [PDF]
Comput Intell Neurosci, 2016 Nowadays, the Colebrook equation is used as a mostly accepted relation for the calculation of fluid flow friction factor. However, the Colebrook equation is implicit with respect to the friction factor (λ). In the present study, a noniterative approach using Artificial Neural Network (ANN) was developed to calculate the friction factor.

Modeling and estimation of internal friction in cloth [PDF]
ACM Transactions on Graphics, 2013 Force-deformation measurements of cloth exhibit significant hysteresis, and many researchers have identified internal friction as the source of this effect. However, it has not been incorporated into computer animation models of cloth. In this paper, we propose a model of internal friction based on an augmented reparameterization of Dahl's model, and ...

Moving horizon for friction state and parameter estimation [PDF]
2013 European Control Conference (ECC), 2013 Efficient on-line state and parameter estimation is essential for model-based friction compensation in order to track changes of friction characteristics in time and space. This paper presents a moving horizon estimation (MHE) algorithm for on-line friction state and parameter estimation using a smoothed (analytic) version of the Generalized Maxwell ...

Data-driven identification of passive friction dynamics with kernel methods [PDF]
Modeling, Identification and ControlThis paper presents a method for data-driven identification of passive systems, with a focus on systems with nonlinear friction models. This is achieved by approximating the passive dynamics of a given system in a reproducing kernel Hilbert space (RKHS).

On Input Market Frictions and Estimation of Factors' Demand [PDF]
Southern Economic Journal, 2011 In this article, we explore the impact of imperfectly competitive input markets on production function estimation. First‐order profit‐maximizing conditions are altered when frictions in input markets cause the elasticity of input supply to the firm to be finite.

Friction Estimation for Tendon-Driven Robotic Hands [PDF]
2021 IEEE International Conference on Robotics and Automation (ICRA), 2021 In tendon-driven robotic hands, tendons are usually routed along several pulleys. The resulting friction is often substantial, and must therefore be modelled and estimated, for instance for accurate control and contact detection. Common approaches for friction estimation consider special dedicated setups, where the parameters of a static or dynamic ...
