  • Publication number: 20240080274
    Abstract: A regular buffer and a shadow buffer are maintained at a receiver host. Responsive to receiving a data flow from a sender host that is clock-synchronized with the receiver host using a common reference clock, a first indication of data of the data flow is stored to the regular buffer, the shadow buffer is transitioned from an idle state to an active state, and a counter of the shadow buffer is incremented that indicates a unit of data traffic received. A dynamic drain rate is determined based on a number of units of the data removed from the regular buffer per unit of time while the shadow buffer is in the active state, where the shadow buffer reverts to an idle state responsive to a break in the receiver host receiving the data flow. Dwell time is calculated as a function of the counter of the shadow buffer and the dynamic drain rate, and a congestion signal for the data flow is determined based on the dwell time.

  • Publication number: 20230351576
    Abstract: The present disclosure relates to a half-cast mark identification and damaged flatness evaluation and classification method for blastholes in tunnel blasting, including the following steps: S1-2: photographing first and second contrast images as well as a half-cast mark image after blasting; S3-6: performing denoising, gray-scale processing and binary processing on the above images, and identifying a boundary of a half-cast mark in each of the images; S7-9: determining a flatness damage variable, a quantitative relation among an area of a half-cast mark region, the damage variable and a fractal dimension, and a damage value of the half-cast mark image; S10-11: forming five-dimensional (5D) eigenvectors to obtain multi-dimensional digital information features of the images; and S12-13: selecting eigenvectors of 60 images as training data to input to a naive Bayes classifier (NBC), and taking eigenvectors of remaining 30 images as classification data to input the above well-trained NBC for classification.
