Modified Discontinuous Pulsewidth Modulation Approach With Independent Phase Loss Adjustment for Voltage Source Converters

open access: yesIEEE Access, 2023
This paper presents an efficient independent phase switching loss reduction technique for 2-level 3-phase voltage source inverters. A modified carrier-based pulse-width modulation algorithm, named per-phase discontinuous pulse-width modulation, is used ...

Revealing a Significant Latent Loss of Dry Matter in Rice Based on Accurate Measurement of Grain Growth Curve

open access: yesAgriculture, 2022
Against the background of increased population and resource depletion, managing food losses means conserving agricultural production resources and increasing farmer income. This paper mainly introduces the discovery and value of latent loss. In 2019, our

Radiative energy loss reduction in an absorptive plasma [PDF]

open access: yes, 2011
The influence of the damping of radiation on the radiative energy loss spectrum of a relativistic charge in an infinite, absorptive plasma is studied. We find increasing reduction of the spectrum with increasing damping.

Optimal Location of FACTS Devices in Order to Simultaneously Improving Transmission Losses and Stability Margin Using Artificial Bee Colony Algorithm

open access: yesIEEE Access, 2021
It is not possible to use the full capacity of the transmission lines due to voltage limitations and stability issues. Therefore, compensators must be used to improve the transmission line capacity.

Building Materials Composition Influence to Sound Transmission Loss STL Reduction [PDF]

open access: yes, 2013
. The development of the airport always causes the noise impact to the surrounding environment.1 Housing close to the airport will be annoyed by the aircraft noise, especially if the building is not added by absorber building materials.

Increasing the Quality Factor (Q) of 1D Photonic Crystal Cavity with an End Loop-Mirror

open access: yesPhotonics, 2021
Increasing the quality factor (Q-factor) of an optical resonator device has been a research focus utilized in various applications. Higher Q-factor means light is confined in a longer time which will produce a sharper peak and higher transmission.

Jet Quenching with Detailed Balance in a Thermal QCD Medium [PDF]

open access: yes, 2002
The effect of detailed balance in induced gluon radiation for an energetic parton propagating inside a quark-gluon plasma is discussed. The stimulated thermal gluon emission reduces while absorption increases the parton's energy.

Tagset reduction without information loss [PDF]

open access: yesProceedings of the 33rd annual meeting on Association for Computational Linguistics -, 1995
A technique for reducing a tagset used for n-gram part-of-speech disambiguation is introduced and evaluated in an experiment. The technique ensures that all information that is provided by the original tagset can be restored from the reduced one.
