Measurement of Event-Related Brain Potentials (ERP) Amplitude and Latency Based on Digital Stochastic Measurement over Interval

open access: yesElektronika ir Elektrotechnika, 2020
In this paper, the measurement of event-related brain potentials (ERP) amplitude and latency based on digital stochastic measurement over interval (DSMI) method are described. Different variations of the measurement system are considered.

Conventional QT variability measurement vs. template matching techniques: comparison of performance using simulated and real ECG.

open access: yesPLoS ONE, 2012
Increased beat-to-beat variability in the QT interval (QTV) of ECG has been associated with increased risk for sudden cardiac death, but its measurement is technically challenging and currently not standardized.

Efficient one-step generation of large cluster states with solid-state circuits [PDF]

open access: yes, 2006
Highly entangled states called cluster states are a universal resource for measurement-based quantum computing (QC). Here we propose an efficient method for producing large cluster states using superconducting quantum circuits.

Statistical analysis of audible noise generated by AC corona discharge from single corona sources

open access: yesHigh Voltage, 2018
Time-domain waveforms of sound pressure pulses generated by alternate current (AC) corona discharge from single corona sources are measured. The pulse amplitude and time interval of sound pressure pulses in positive and negative half cycles are analysed ...

Comparison of Interpolators Used for Time-Interval Measurement Systems Based on Multiple-Tapped Delay Line

open access: yesMetrology and Measurement Systems, 2017
The paper describes the construction, operation and test results of three most popular interpolators from a viewpoint of time-interval (TI) measurement systems consisting of many tapped-delay lines (TDLs) and registering pulses of a wide-range changeable

Research on positioning and re-measurement mechanism of underground precise personnel positioning system

open access: yesGong-kuang zidonghua, 2022
During the underground transmission of wireless signal, the measurement between card reader and marker card fails due to signal strength attenuation and interference.

Compensation of Accuracy Error for Time Interval Measurements

open access: yesLatvian Journal of Physics and Technical Sciences, 2023
A method of accuracy error compensation for the time interval is examined, allowing to eliminate the dependence of accuracy error on the duration of measured intervals and minimising the influence of destabilising factors - ambient temperature changes and the initial deviation of the meter clock generator frequency from the nominal value.

Information thermodynamics for a multi-feedback process with time delay

open access: yes, 2016
We investigate a measurement-feedback process of repeated operations with time delay. During a finite-time interval, measurement on the system is performed and the feedback protocol derived from the measurement outcome is applied with time delay.

A new technique for the determination of the critical current density in superconducting films and flat samples [PDF]

open access: yes, 2012
The determination of their critical current density in the whole range of the temperature below Tc is of first importance to understand the physical processes occurring in superconducting films.
