On the basis of the mathematical model, the equations have been derived. They are simulated by VB program language. The residence time and the position of a particle at any moment can be defined according to rotational speed of the rotary dryer, radius of the drum, the slope of the drum, wind-force and the particle quality. Simulated results are satisfactory.
Since Volker Strassen proposed a recursive matrix multiplication algorithm reducing the time complexity to n2.81 in 1968, many scholars have done a lot of research on this basis. In recent years, researchers have proposed using computer algorithms to solve fast matrix multiplication problem. They have found Strassen's algorithm or other algorithms that have the same time complexity as Strassen algorithm...
The intelligent operation of circuit breaker can choose and adjust the fit prearranging work condition of the interrupter and/or operating mechanism automatically accordance with the opening message that is sent from power system, in order to improve the SF6 dielectric recovery strength. Under the conditions of breaking, the electric field and flow field of arc chamber have been calculated. Simulation...
Respiratory failure may be caused by a number of pathological processes. Often the only applicable treatment is to ventilate the patient with a machine, the mechanical ventilator that provides a controlled flow of gas into a patient's airways to substitute or support his own breathing. Since there are a huge variety of pathologies and many available modes of ventilation to deal with them, it is important...
On the basis of a macroscopic spin wave-diffusion theory we study high-frequency spin transport through a junction composed of a magnetic and a nonmagnetic layer. We illustrate the consequences of the spin wave-diffusion theory for the spatio-temporal dynamics of a spin current, and apply the theory to the calculation of the dynamical impedance of the junction. For low modulation frequencies, our...
