PIECEWISENonlinear approximation is widely used in signal processing. Real-life signals can be modeled as functions of bounded variation. Thus the variable knot of approximating function could be self- adaptively chosen by balancing the total variation of the target function. In this paper, we adopt...

Here, u(t) is a second piecewise-constant functions. In this way, the model (1j) is solved with no controls for t≤t0; controls are introduced at time t0. The time t0 is fixed. For consistency, the following bounds apply to u(t): (9b)0≤u(t)≤1,t∈[t0,T]. The piecewise-...
In turn, each curve is represented by a set of linear functions, which requires binary variables to indicate which one is being used for each hydro plant. An incremental model is then implemented to search for the solution within the set of linear functions of the selected curve. The work ...
