A Novel Technique to Control the Accuracy of a Nonlinear Fractional Order Model of COVID-19: Application of the CESTAC Method and the CADNA Library [PDF]
Mathematics, 2021 In this paper, a nonlinear fractional order model of COVID-19 is approximated. For this aim, at first we apply the Caputo–Fabrizio fractional derivative to model the usual form of the phenomenon.

A Novel Method for Solving Second Kind Volterra Integral Equations with Discontinuous Kernel
Mathematics, 2021 Load leveling problems and energy storage systems can be modeled in the form of Volterra integral equations (VIE) with a discontinuous kernel. The Lagrange–collocation method is applied for solving the problem. Proving a theorem, we discuss the precision

Investigating mixed-precision for AGATA pulse-shape analysis [PDF]
EPJ Web of Conferences, 2023 The AGATA project aims at building a 4π gamma-ray spectrometer consisting of 180 germanium crystals, each crystal being divided into 36 segments. Each gamma ray produces an electrical signal within several neighbouring segments, which is compared with a ...

Days of Future Past: Why Race Matters in Metadata [PDF]
Genealogy, 2022 While marginalized as a juvenile medium, comics serve as an archive of our collective experience. Emerging with the modern city and deeply affected by race, class, and gender norms, comics are a means to understand the changes linked to identity and ...

A new version of the CADNA library for estimating round-off error propagation in Fortran programs
Computer Physics Communications, 2010 International audienceThe CADNA library enables one to estimate, using a probabilistic approach, round-off error propagation in any simulation program. CADNA provides new numerical types, the so-called stochastic types, on which round-off errors can be ...

CADNA: a library for estimating round-off error propagation
Computer Physics Communications, 2008 International audienceThe CADNA library enables one to estimate round-off error propagation using a probabilistic approach. With CADNA the numerical quality of any simulation program can be controlled. Furthermore by detecting all the instabilities which
