Partial Discharge Analysis and Simulation Using the Consecutive Pulses Correlation Method

open access: yesEnergies, 2021
The behaviour of partial discharge as consequences of an alternating current (AC) is already well defined. AC partial discharges have completely different behaviour, background physics and parameters than partial discharges (PD) under direct current (DC)

Generalisation of new sequence knowledge depends on response modality. [PDF]

open access: yesPLoS ONE, 2013
New visuomotor skills can guide behaviour in novel situations. Prior studies indicate that learning a visuospatial sequence via responses based on manual key presses leads to effector- and response-independent knowledge.

Tool-Path Problem in Direct Energy Deposition Metal-Additive Manufacturing: Sequence Strategy Generation

open access: yesIEEE Access, 2020
The tool-path problem has been extensively studied in manufacturing technologies, as it has a considerable impact on production time. Additive manufacturing is one of these technologies; it takes time to fabricate parts, so the selection of optimal tool ...

Precise BER Formulas for Asynchronous QPSK-Modulated DS-CDMA Systems Using Random Quaternary Spreading Over Rayleigh Channels

open access: yes, 2008
Precise bit-error-ratio (BER) analysis of an asynchronous QPSK-modulated direct-sequence code-division multiple-access system using random quaternary spreading sequences for transmission over Rayleigh channels is performed based on the characteristic ...

Direct sequence spread spectrum: history, principles and modern applications

open access: yesVojnotehnički Glasnik
Introduction/purpose: Direct sequence spread spectrum modulation is widely used in many radiocommunications systems. At the first time, this modulation technique was used in military communications and navigation systems.

Direct-Sequence-CDMA in Highly Sensitive Indirect Time-of-Flight Distance Sensor

open access: yesIEEE Photonics Journal, 2023
This work presents the application of Direct-Sequence Code-Division-Multiple-Access (DS-CDMA) to tackle the primary problem of simultaneous multi-access of a shared light channel in an indirect Time-of-Flight measurement system based on on-off-keyed (OOK)
