The invention discloses a control method and system for Q-time interval products. The method comprises the following steps: acquiring the parameters of the current Q-time interval processing procedure; calculating the weights of all steps in the current Q-time interval by a weight calculation ...
At different periods of its evolution and in different zones along its length, the TFZ has distinct geological features that control gold mineralization. In the northeastern part of the TFZ, early-stage faulting activity (from the Jurassic to Cretaceous) is associated with abundant calc-alkaline ...
In order to simultaneously control the current and pressure profiles in high performance tokamak plasmas with internal transport barriers (ITB), a multi-variable model-based technique has been proposed. New algorithms using a truncated singular value decomposition (TSVD) of a linearized model operator...
