TA, the applied time of the vector V¯APWM plays an important role in generating sinusoidal waveform for variable voltage variable frequency drives (VVVFD's) with a minimum harmonic level. PWM techniques have many methods in implementation ranging from a relatively simple method such as ...
17.A Modified Phase Method Based on First Harmonic of Fourier Series for Measuring Nanosecond Fluorescence Lifetime;基于一级傅立叶级数相调制法的纳秒级荧光寿命测量 18.He will likely progress as a Knight, and become a 4th Level Man-at-arms / 3rd Level Knight.他可能喜欢晋阶一级骑士,变成战士4...
As to the single-particle basis vectors, the eigenfunctions of the three-dimensional harmonic oscillator potential were taken as usual. Also, the contributions from the Fujita–Miyazawa three-nucleon force (3NF)70 were added in the form of the effective NN interaction40. The Fujita–Miyazawa force...
Based on equation (1), a high S needs a high DOS (or md∗) at given Fermi level (carrier concentration). Since md∗=Nv2/3mb∗, where Nv is the band degeneracy and mb∗ is the band effective mass. There are two methods to increase the md∗, including increasing the ...

Guodong Liu5 & Zhenxiang Cheng2 In this paper, we have investigated the structural, electronic, magnetic, half-metallic, mechanical, and thermodynamic properties of the equiatomic quaternary Heusler (EQH) compound FeCrRuSi using the density functional theory (DFT) and the quasi-harmonic Debye model...
Equation (7) is similar to the approach used in the CSHE method described in previous studies8,9. In these studies, the electrostatic potential of water was employed for alignment instead of the O 1s level. As shown by the gray dashed line in Fig.1c, using the electrostatic potential, ...
hardness, thermal conductivity, elastic wave velocity and thermodynamic properties of magnesite under high pressure are investigated using the first-principles calculations based on density functional theory with generalized gradient approximation (GGA) combined with the quasi-harmonic approximate Debye model. ...
The first-passage time is proposed as an independent thermodynamic parameter of the statistical distribution that generalizes the Gibbs distribution. The theory does not include the determination of the first-passage statistics itself. A random process is set that describes a physical phenomenon. The fi...
Lemma 4.2 is reminiscent of Theorem 2.1 (ii) of [25], except that the boundedness assumption of the function satisfying the harmonic equation in [25] is replaced by a weaker assumption of logarithmic growth. We now turn to justifying that an expansion of the form (43) provides a ...
