Effective capacity optimization for UDN
IET 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).

Effects of obesity on functional capacity [PDF]
Obesity, 2013 ObjectiveTo assess the relationships between BMI and walking speed, balance control, sit‐to‐stand performance (a measure of mass specific lower limb power), and endurance.Design and MethodsThirty‐six women with a BMI ≥ 30 kg/m2and 10 women with normal body weight (BMI between 18 kg/m2and 25 kg/m2) were enrolled in this observational study.

Heat capacity of PbS: Isotope effects [PDF]
Physical 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

A New Method for Drawing the Capacity Spectrum for Seismic Analysis and Structural Rehabilitation [PDF]
Journal of Rehabilitation in Civil Engineering, 2020 A review of previous studies shows that there are two general views on how to determine demand in structures through incremental nonlinear static analysis. In the first view, multi-modal methods are used to determine demand in structures.
