Neuromorphic Log-Domain Silicon Synapse Circuits Obey Bernoulli Dynamics: A Unifying Tutorial Analysis

open access: yesFrontiers in Neuroscience, 2015
The field of neuromorphic silicon synapse circuits is revisited and a parsimonious mathematical framework able to describe the dynamics of this class of log-domain circuits in the aggregate and in a systematic manner is proposed.

Development of Fractional Order Modeling of Voltage Source Converters

open access: yesIEEE Access, 2020
This paper proposes a mathematical fractional order modelling of Voltage Source Converters (VSC). Fractional behaviour helps to model and describe a real object more accurately than the integer order model.

Now you see it, now you don’t - Cognitive skills and their contributions to mathematics across early development

open access: yesJournal of Cognition, 2023
A broad variety of domain-specific (e.g., non-symbolic magnitude comparison and arithmetic) and domain-general (e.g., spatial skills and inhibition) skills have been identified as precursors to mathematics achievement.

Exact asymptotic behavior of magnetic stripe domain arrays [PDF]

open access: yes, 2012
The classical problem of magnetic stripe domain behavior in films and plates with uniaxial magnetic anisotropy is treated. Exact analytical results are derived for the stripe domain widths as function of applied perpendicular field, $H$, in the regime ...

Technical Analysis Techniques versus Mathematical Models: Boundaries of Their Validity Domains [PDF]

open access: yes, 2006
We aim to compare financial technical analysis techniques to strategies which depend on a mathematical model. In this paper, we consider the moving average indicator and an investor using a risky asset whose instantaneous rate of return changes at an unknown random time. We construct mathematical strategies.

A spatial epidemic model with a moving boundary

open access: yesInfectious Disease Modelling, 2021
We present a new mathematical model to investigate the spatial spread of an infectious disease. The model consists of a nonlinear PDE system with an unknown velocity field, defined on an epidemic domain that changes with time.
