Nu is used more often when specifying electromagnetic waves, such as light, X-rays, and gamma rays. Omega is usually used to describe the angular frequency—that is, how much an object rotates or revolves in radians per unit time. Usually, frequency is expressed in the hertz unit, named i...
The meaning of ANGULAR FREQUENCY is frequency of a periodic process (as electric oscillation or sound vibration) expressed in radians per second, equivalent to frequency in cycles multiplied by 2π.
Fig. 5. Identified parameters using different models (upper panels: 0DHT_maD_LDF; lower panels: 1DHT_miLDF) over the effective loading for 40°C and different coating thicknesses (different colours and symbols); the LDF parameter kLDF is expressed as the micropore transport diffusivity Dmi acc...
This representation leads immediately to the instantaneous power, given by |s(t)|2, which shows how the energy of the signal is distributed over time; the total signal energy is expressed as: Es=∫−∞∞|s(t)|2dt. But the time-domain description has limitations, as may be seen by ...

The model QED Hamiltonian used in this work is expressed as31,32,33 $$\hat{H}=\frac{{\hat{P}}^{2}}{2M}+E(R)+{\hat{H}}_{{\rm{vib}}}+\frac{{\hat{p}}_{{\rm{c}}}^{2}}{2}+\frac{1}{2}{\omega }_{{\rm{c}}}^{2}{\left({\hat{q}}_{{\rm{c}}}+\sqrt{\...
Again, strength is expressed in a logarithmic scale using decibels (dB). RF signal strength (or RF “signal”) is expressed as dBm, with a reference of 1 mW of RF power. That is, 0 dBm = 1 mW RF power. RF signal strength in dBm is the logarithm of the RF power in mW. dBm=...
An index of dialysis dose is the fractional clearance of urea, which is commonly expressed as Kt/V. It can be calculated from blood urea concentration and haemodialysis (HD) parameters, according to the respective urea kinetic model or by means of simplified formulas. Similar principles are ...
After implementation of NOMA, user Umwill decode its message signal simply by considering user Un’s message as noise and the achievable data rate Rm1is expressed as [9]: (1)Rm1=log21+hm2αm2hm2αn2+1ρ where ρis transmit SNR. While the user Unwill undergo SIC phenomenon, it will ...
absolute frequency is a simple count of the number of times a value is observed. Absolute frequency is usually expressed as a whole number and is considered a very basic level of statistical analysis.
