T a new major technological advance is available that can help control-valve users avoid many of the problems and inefficiencies associated with using compressed air as a power medium. The new solution uses electric power and eliminates dependence on compressed air. This totally electric solution is appropriate and cost-effective for a wide variety of control-valve applications, including those...

Objectives: The purpose of this study was to evaluate whether intra-canal application of controlled direct electric current (DEC) could accelerate the amount of orthodontic tooth movement (OTM) in young adult mixed breed dogs. Methods: Fourth premolars of both jaws of five young adult mixed breed dogs were divided into two groups of control and experimental groups. Orthodontic force...

In order to rationally design the capacity of each energy coupling unit integrated system, effectively coordinate and optimize control system equipment. This paper proposes an improved cloud adaptive particle swarm algorithm method. First, three busbars multi-energy equipment models based on electric, thermal, gas loads are established, then model has better global optimization capabilities def...
