To address these issues, a two-level piecewise linear model is proposed to model the degradation path. At the first level, the degradation characteristic of each track section is modelled by a piecewise linear model with known break points at the tamping times. At the second level, ...
[1] A piecewise linear model is developed to detect climatic trends and their structural changes in time series with a priori unknown number and positions of breakpoints (BPs). The departure (i.e., the initial noise term) of trends from time series is allowed to be interpreted by the first...

The piecewise-linear method has also compared favourably to other large strain formulations in subsequent studies. This paper presents a dimensionless piecewise-linear numerical model for one-dimensional consolidation called Consolidation Settlement 2 (CS2). CS2 accounts for large strain, soil self-weight...
Error Analysis and Model Adaptivity for Flows in Gas Networks In the simulation and optimization of gas flow in a pipeline network, a hierarchy of models is used that employs different formulations of the Euler equations. While the optimization is performed on piecewise linear models, the flow sim...
This paper is mainly devoted to the study of the limit cycles that can bifurcate from a linear center using a piecewise linear perturbation in two zones. We consider the case when the two zones are separated by a straight line ∑ and the singular point of the unperturbed system is in ∑...
In this paper, we propose a piecewise linear thermal model of a building. To learn the model, we present a Kalman filter based approach for estimating the parameters. Finally, we fit the piecewise linear model to data collected from a residential building with a forced-air heating and ...
This study proposes a new approach to solve the transmission expansion planning (TEP) problem considering that the network is represented by a non-linear model. Non-linear constraints are approximated with piecewise-linear (PWL) functions, which renders TEP a mixed-integer linear programming (MILP)...
An efficient piecewise linear approximation of a nonlinear function (PLAN) is proposed. This uses a simple digital gate design to perform a direct transformation from X to Y, where X is the input and Y is the approximated sigmoidal output. This PLAN is then used within the outputs of an ar...
The piecewise-linear model of a continuous bistable system is considered. Two different classes of the fronts, namely the bistable fronts (BFs), which perf... Bakanas,R - 《Nonlinearity》 被引量: 15发表: 2002年 On the Quadratic Finite Element Approximation of 1D Waves: Propagation, Observation...
