The growth of cities is an unstoppable phenomenon that began in the last century and will undoubtedly be one of the challenges of the current century. It is not only a question of urbanization; its implications and consequences extend to the economy, society, culture and the environment. The c...
The energy imparted to the secondary particles is independent of the intensity, and depends only on the frequency of the light (according to the law ɛ = hv). The number of observations confirming this property of light increased year by year and the situation arose that the simultaneous ...
Consider the waves described immediately above, but limit the discussion to harmonic motion of frequency ω. One of the waves takes the form: (65)p=Acoskx−ωt where k = ω/c = 2π/λ and λ = wavelength of the sound. This equation can also be written in the form: (66)p=Acos...

which is a function of time step Δt, mesh size Δx, and frequency. Unconditionally unstable example For the scheme defined by Eq. (11.74a), Eq. (11.81b) becomes (11.81e)A−1+jσsinϕ=0. The satiability condition in Eq. (11.81c) requires the modulus of the amplification factor ...

For a state to state transfer, we derive a family of control fields depending upon two free parameters, which allow us to adjust the efficiency, the time and the robustness of the control process. As an illustrative example, we consider the quantum analog of the tennis racket effect, which ...
all references to this temperature are expressed asTin this manuscript. Taking into account the quality of the data and to avoid bias-processing, none smooth or interpolation was performed to the raw data. Each frequencyfcorresponding to each temperatureTserves as the metric for the relaxation time...
