the reaction of ch3o2 radicals with acetaldehyde on the solid surface of nh4no3 has been studied in a flow capillary reactor at low pressure and room temperature. the experiments were performed using epr spectrometer combined with the kinetic method of radicals freezing. peroxy radicals revealed an oscillation complex behavior during the process regarding to the phenomenon of radicals multiplic...

The objective of this paper is to examine the effectiveness of wall oscillation as a control scheme of drag reduction. Two flow configurations are considered: constant flow rate and constant mean pressure gradient. The Navier-Stokes equations are solved using Fourier-Chebyshev spectral methods and the oscillation in sinusoidal form is enforced on the walls through boundary conditions for the sp...

– One of the important applications of robots is in material handling and transport of various shaped objects. In cases where an object cannot be directly grasped by the robot gripper, and must be carried by a hook, it may be subject to undesirable swings during transport. This paper presents an analytical method for minimizing the oscillation of a suspended object during transport. This method...

Software defined network (SDN) is a new network architecture in which the control function is decoupled from the data forwarding plane, that is attracting wide attentions from both research and industry sectors. However, SDN still faces the energy waste problem as do traditional networks. At present, research on energy saving in SDN is mainly focused on the static optimization of the network wi...

Cooperative adaptive cruise control (CACC) realizes efficient, intelligent of vehicle acceleration, deceleration, and steering, through inter-vehicle communication cooperative control. However, the close combination platoon makes it difficult for other vehicles to cut-in, which can lead severe traffic jams on certain sections road. The effect CACC depends penetration rate, is percentage connect...

• We propose a method to analyze oscillation characterizations by mechanical vibrations. elucidate differences between damping behavior and instability analyses. reveal inherent frequency intensity enhance reliability. illustrate resonance perturbation which will cause the severest oscillatory traffic. Connected automated vehicles (CAVs), built upon advanced vehicle control communication techno...
