In this paper, model based on the Fourier series has been used in studies of the transient thermal behavior of semiconductor devices. An explicit expression for the temperature space-time dependence has been derived. Keywords—thermal; transient; analytical; semiconductor;

Many cities in the Global South are structurally different from Northern, particularly American, on which much of urban sociology’s conceptual apparatus has been based. Thus, depicting them terms a standard vocabulary risks imposing an inappropriate way seeing. We need that is able to accommodate their experience. This special issue contributes work building vocabulary. select five keywords soc...

The Fano-Kondo effect in zero-bias conductance is investigated based on a theoretical model for the T-shaped quantum dot. The conductance as a function of the gate voltage is generally characterized by a Fano asymmetric parameter q. With varying temperature the conductance shows a crossover between the high and low temperature regions compared with the Kondo temperature TK: two Fano asymmetric ...

We present the results of a small study involving the use of keyword-filler hidden Markov models (HMM) for spotting keywords in continuous speech. The performance dependence on the amount of keyword training data and the choice of model parameters is documented. Also, we demonstrate a strong correlation between individual keyword spotting performance and median duration of that keyword. This de...
