A traceable time interval measurement with a reduced uncertainty
International Journal of Metrology and Quality Engineering, 2015 Time interval (TI) is one of the basic quantities. Its measurement is not included only in the activities running in the time and frequency metrology but also included in the measurement of many other quantities that depend on time ...

Measuring Electromechanical Coupling in Patients with Coronary Artery Disease and Healthy Subjects
Entropy, 2016 Coronary artery disease (CAD) is the most common cause of death globally. To detect CAD noninvasively at an early stage before clinical symptoms occur is still nowadays challenging. Analysis of the variation of heartbeat interval (RRI) opens a new avenue

Time Measurement in Quantum Gravity [PDF]
, 1994 We discuss time measurement in quantum gravity. Using general relativity for large distances and the uncertainty principle we find a minimum time interval of the order of the Planck time, therefore the uncertainty in time measurment is bounded from below.

Data Representation Based on Interval-Sets for Anomaly Detection in Time Series
IEEE Access, 2018 Anomaly detection in time series is a popular topic focusing on a variety of applications, which achieves a wealth of results. However, there are many cases of missing anomaly and increased false alarm in most of the existing works.
