Electrocardiogram (ECG) is a technique of understanding the functioning of heart. Each
segment of the ECG signal is significant for the detection of different heart problems …

In this paper, we propose a frequency tracking algorithm based on an Extended Kalman
Filter (EKF). We introduce a generalized state space model to estimate and track frequency …

Biopotential signals are mainly characterized by low amplitude and thus often distorted by
extraneous interferences, such as power line interference in the recording environment and …

Condition monitoring of mechanical systems is an important topic for industry since it
improves machine maintenance and reduce the total associated operational cost. In this …

Cardiac diseases constitute a major root of global mortality and they are likely to persist.
Electrocardiogram (ECG) is widely opted in clinics to detect countless heart illnesses …

A discrete-time linear Kalman filter is presented for removing power-line interference from
biomedical recordings. The theoretical aspects of this filter, the relationship with …

In this paper, an approach is proposed for the application of an extended Kalman filter (EKF)
to a sensorless stepper motor drive, when the motor is separated from its drive by long …

Abstract Hybrid Stepper Motors are widely used in open-loop position applications. They are
the choice of actuation for the collimators in the Large Hadron Collider, the largest particle …

The paper proposes a digital band-pass filter designed to extract power-line interferences
from ECG signals. The filter is called “reduced” because it processes samples that are …

Develop of wearable cardiac monitors is becoming an important field of research because
Cardiovascular disease is the leading cause of morbidity and mortality in the world. Real …
