A non-linear theory of infrahyperfunctions [PDF]

open access: yes, 2019
We develop a nonlinear theory for infrahyperfunctions (also referred to as quasianalytic (ultra)distributions by L. H\"{o}rmander). In the hyperfunction case our work can be summarized as follows.

Strong Noise Rejection in VLC Links under Realistic Conditions through a Real-Time SDR Front-End

open access: yesSensors, 2023
One of the main challenges in the deployment of visible light communication (VLC) in realistic application fields, such as intelligent transportation systems (ITSs), is represented by the presence of large background noise levels on top of the optical ...

Non‐linear canonical correlation† [PDF]

open access: yesBritish Journal of Mathematical and Statistical Psychology, 1983
Non‐linear canonical correlation analysis is a method for canonical correlation analysis with optimal scaling features. The method fits many kinds of discrete data. The different parameters are solved for in an alternating least squares way and the corresponding program is called CANALS.

FPGA implementation of adaptive sliding mode control and genetically optimized PID control for fractional-order induction motor system with uncertain load

open access: yesAdvances in Difference Equations, 2017
In this paper, we investigate the control of 4-D nonautonomous fractional-order uncertain model of a PI speed-regulated current-driven induction motor (FOIM) using a fractional-order adaptive sliding mode controller (FOASMC).

Human Stress and StO2: Database, Features, and Classification of Emotional and Physical Stress

open access: yesEntropy, 2020
Emotional and physical stress can cause various health problems. In this paper, we used tissue blood oxygen saturation (StO2), a newly proposed physiological signal, to classify the human stress. We firstly constructed a public StO2 database including 42
