DOI: 10.1016/j.applthermaleng.2017.07.167
Abstract: Thermal time constants (TTC) of a thermal dynamic model reflect the change rate of temperature, which are affected by many factors such as load current, oil temperature, etc. In this study, relative thermal time constants… read more here.

DOI: 10.1063/1.5086037
Abstract: A major factor that hinders the realization of indium oxide (IO) as a potential gas/photosensor is the response time, which is quite poor. For instance, the photoresponse of dc sputtered IO films under UV and… read more here.

DOI: 10.1109/tmtt.2019.2921338
Abstract: This paper provides theoretical and experimental evidence that, contrary to what is a widely reported belief, the capture time constant of GaN high-electron-mobility transistor (HEMTs) deep-level traps is not infinitesimally shorter than the modulation envelope… read more here.

DOI: 10.3389/fnins.2022.779062
Abstract: Automatic speech recognition (ASR), when combined with hearing-aid (HA) and hearing-loss (HL) simulations, can predict aided speech-identification performances of persons with age-related hearing loss. ASR can thus be used to evaluate different HA configurations, such… read more here.
