When damping is governed by a single relaxation time τ, the frequency dependence of material damping is a Debye peak given by [4] (2).
When damping is governed by a single relaxation time τ, the frequency dependence of material damping is a Debye peak given by[4] Q material - 1 = Δ ω τ 1 + ω τ 2 (2).
To this purpose, different methods and probes were comparatively used to infer, noninvasively, the relationship between the water content of stone materials and the reflection properties at microwave frequency of the material.
In the case of Deadpool – which earlier this week became the best-performing R-rated film ever – the frequency of inappropriate material meant a compromise could not be met.
They proposed an inventory model to jointly optimize the replenishment frequency of raw material, the production rate, the replenishment cycle of the product, and the retail price.
Effect of finite conductivity of FGM on electrostatic and Casimir attractions is incorporated via relative permittivity and plasma frequency of the material.
where ω ∗ Open image in new window is the characteristic frequency of the material, and c 1 Open image in new window is the longitudinal wave velocity of the medium.
Using QQ chat rooms, it's very convenient for the teacher to upload the necessary materials for students to learn in their spare time, but it also presents a problem: who downloaded the material and who didn't are unknown because the actual users' names wouldn't be shown when downloading took place; what's shown is the total downloading frequency of a material.
With QQ or Wechat as a communication platform, who downloaded the material and who didn't are unknown because the actual users' names are not shown when downloading took place; what's shown is the total downloading frequency of a material.
Risk factors for SAB were also similar apart from an increased frequency of prosthetic material in the IDC group (72.2% vs 46.7%, p=0.04; table 3).
