Effective capacity optimization for UDN

open access: yesIET Communications, 2022
Abstract For the ultra‐dense distributed network (UDN), the intensive deployment leads to the collision problem of the unlicensed spectrum access due to the random contention access mechanism of the unlicensed spectrum, which is difficult to improve the user quality of service (QoS).

Effective Capacity Analysis Over Generalized Composite Fading Channels

open access: yesIEEE Access, 2020
A performance analysis of the effective capacity in two recently proposed generalized composite fading channels, namely $\kappa $ - $\mu $ /inverse gamma and $\eta $ - $\mu $ /inverse gamma composite fading channels, is conducted. To this end, accurate

Heat capacity of PbS: Isotope effects [PDF]

open access: yesPhysical Review B, 2007
In recent years, the availability of highly pure stable isotopes has made possible the investigation of the dependence of the physical properties of crystals, in particular semiconductors, on their isotopic composition. Following the investigation of the specific heat ($C_p$, $C_v$) of monatomic crystals such as diamond, silicon, and germanium, similar
