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. ...
2a,b). Then we relax xRE and xGe at different c/a ratios and again fit the total energy to the Murnaghan equation of state in order to obtain the equilibrium c/a ratio (Fig. 2c,d) as well as the bulk modulus and its pressure derivative. Table 1 shows that AF ordering significantly...
In [82], a diffusing particle of mass m trapped by a harmonic potential of strength k and pulled by a constant force [Math Processing Error]F0 is considered; the force in the Langevin equation [Math Processing Error]F(X(t))=-kX(t)[Math Processing Error]+F0 includes the externally ...
Some simple control systems (which includes the control of temperature, level and speed) can be modelled as a first-order linear differential equation: (3.5)τdYdt+Y=kX where X and Y are the input and output, respectively, τ denotes the system time constant and k is the system gain. Whe...
technique with Fourier series similar to Forbes and Crozier (2002) but incorporate the timeharmonic Green’s function in obtaining an expression for the magnetic field rather than using the Biot–Savart law. Again this leads to a highly ill-conditioned integral equation which is then solved v RF...
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 ...
intensities calculated numerically from particle trajectories using Equations (1)–(4) and with the analytical expression given by Equation (5) are presented in Figure 4; with a temporal sampling rate sufficient to accurately reproduce the field profile, the results exhibit an excellent level of ...
The gap between the frequencies of acoustic and optical modes is a function of differences in the masses of the atoms that make up the compounds. The masses’ difference is directly proportional to the gap in the frequencies. The thermodynamic properties are obtained from the quasi-harmonic Debye...
