Computational modeling of selective laser melting process
Published 2020“…In the study, the melt pool is considered to be in conduction-mode when the ratio of the melt pool depth to the melt pool width is less than 0.5 and keyhole-mode when the ratio is above 1.0. The region between the conduction-mode and the keyhole-mode is known as the transient-mode. …”

Continuous health-based optimal operation and control for mission-critical power systems
Published 2024“…A novel way to include the thermal constraint is presented in this thesis considering the magnetic density limitation on the knee point of magnet, along with proposed demagnetization fault indicator and magnet temperature limitation. A safe operating region as presented in first part of the thesis is utilized in the generator capability curve, and variation due to electrical and thermal limits are updated in real-time for three-stage successive relaxation optimization to dispatch optimal current. …”

Signal processing for cooperative cognitive radio networks
Published 2017“…Moreover, presuming the possible usage of the CRN concepts in new wireless technologies such as device-to-device (D2D) communication over Long Term Evolution Advanced (LTE-A) standard, it motivates us to think beyond the traditional applications of the CRN by considering some other parameters such as randomness in the number of available secondary users and higher traffic rate of the primary users as compared with the wireless regional area network (WRAN - IEEE 802.22). In this dissertation, we focus on some possible complexities which may be faced when the CSS has been utilized. …”

New measurements of neutrino oscillation parameters and development of novel interaction uncertainties at current and future long-baseline experiments
Published 2024“…</p> <br> <p>First, parameters were developed at T2K to describe sizeable model differences seen in the low-energy transfer region. These parameters were further motivated by an alternative model study that demonstrated a significant bias in ∆<em>m</em><sup>2</sup><sub>32</sub>, which was the largest contribution to the total systematic uncertainty for this parameter. …”

Design and growth of high-power gallium nitride light-emitting diodes
Published 2014“…Besides, InGaN/GaN LEDs grown along polar-orientations (i.e., c+/c- orientations) suffer from the QCSE in the MQWs, which significantly reduces the spatial overlap of the electron-hole wave functions,and thus decreases the radiative recombination rates in the device active region. We have designed and demonstrated that the QCSE can be effectively suppressed by Si step-doping the quantum barriers,which enhances the optical output power and external quantum efficiency (EQE). …”

The effects of atmosphere-ocean-wave coupling during tropical cyclone
Published 2018“…Model results have shown that coupling a wave model enhances the momentum flux from atmosphere to ocean, where this enhanced momentum flux acts to reduce the wind speeds in high wind region, while increasing the enthalpy flux. Additionally, the coupling of ocean model affects the intensity of modelled TC, where the reduced sea surface temperature decreases the intensity of TC. …”

Published 2025“…However, the significance of such regional factors is not yet clear. While probably insignificant to the doxographical arrangements of texts within the editions (which of course reflects doctrinal thinking), regionality might however be of much greater significance in terms of the actual exemplars used for copying, and hence to transmissional and text-critical concerns of all kinds.…”
