On the chaotic systems of attraction with fractional operators in a novel Lorenz system
Results in Control and OptimizationIn this research, a novel variant model of the classical Lorenz system is proposed by reformulating both the classical and fractional-order Lorenz systems through a new framework based on piecewise fractional derivatives.

Fractional Calculus of Piecewise Continuous Functions
Fractal and FractionalThe fractional derivative computation of piecewise continuous functions is treated with generality. It is shown why some applications give incorrect results and why Caputo derivative give strange results. Some examples are described.

Non‐linear activation function approximation using a REMEZ algorithm
IET Circuits, Devices and Systems, 2021 Here a more accurate piecewise approximation (PWA) scheme for non‐linear activation function is proposed. It utilizes a precision‐controlled recursive algorithm to predict a sub‐range; after that, the REMEZ algorithm is used to find the corresponding ...

Prostate cancer survival estimates: An application with piecewise hazard function derivation
South Asian Journal of Cancer, 2019 Abstract Background: The hazard function is defined as time-dependent. However, it is an overlooked area of research about the estimation of hazard function within the frame of time. The possible explanation could be carried by estimating function through the changes of time points.
