Abstract: A method for preventing sudden subsidence of an open caisson in a soft foundation includes the following steps: a position of the open caisson is determined; grouting is carried out to reinforce a foundation of the open caisson; an open caisson manufacturing site is leveled; sections of the open caisson are manufactured and installed; the step of sections of the open caisson are manufactured and installed is repeated until all the sections are manufactured and the open caisson subsides in place as a whole.

Abstract: A carrier device and a placement machine, where the carrier device includes a body and a positioner. A positioning sucker mechanism is disposed on the body, and a sliding sucker mechanism is slidably disposed on the body, where the sliding sucker mechanism includes a sucker group, a positioning block connected to one end of the sucker group, and a first suction piece provided on the positioning block. The positioner is arranged on one side of the body and adjacent to the positioning block, and includes a driver and a clamping assembly connected to the driver, where the clamping assembly is provided with a second suction piece mutually attracted to the first suction piece.

Abstract: Disclosed is a method for preventing sudden subsidence of an open caisson in a soft foundation, which includes the following steps: a position of the open caisson is determined; grouting is carried out to reinforce a foundation of the open caisson; an open caisson manufacturing site is leveled; sections of the open caisson are manufactured and installed; the step of sections of the open caisson are manufactured and installed is repeated until all the sections are manufactured and the open caisson subsides in place as a whole. The application is suitable for construction on soft soil, loss caused by the phenomenon of sudden subsidence may be avoided, and personal safety of constructors may be guaranteed.

Abstract: Disclosed are a degassing machine and a degassing system. The degassing machine includes a machine body defined with a containing groove, an inner wall of the containing groove being provided with an electric control terminal; and a furnace body including: an upper cover fixed on a wall of the containing groove and a drawer slidably provided in the containing groove. The drawer is provided with a contact terminal corresponding to the electric control terminal, and is for placing a workpiece.

Abstract: A buffer circuit, a frequency dividing circuit, and a communications device are disclosed. The buffer circuit includes a buffer, a first control circuit, and a second control circuit. The buffer is coupled to a frequency divider, and the buffer is configured to receive a first signal output by the frequency divider, and output a fourth signal by using an output terminal of the buffer circuit when driven by the first signal, where the first signal is obtained by the frequency divider by performing frequency division on a group of differential signals, and the differential signals include a second signal and a third signal. The first control circuit is configured to perform delay control on a rising edge of the fourth signal based on the second signal. The second control circuit is configured to perform delay control on a falling edge of the fourth signal based on the third signal.

Abstract: Prediction models for managing viewership data are disclosed. An amount of time users are displayed content is initially obtained. The obtained amounts may be for each content distributor that distributes channels, for each of the channels with respect to which sets of content are displayed, for each of the sets that comprises content displayed during past periods, and for each of the displayed content. A set of features associated with each of the displays is obtained and a target period is selected from among the past periods. A model is used to predict an amount of time users were displayed content during the target period, for each of the sets, channels, and distributors, based on the obtained sets of features associated with the displays during the target period and on the obtained amounts for the displays during the past periods that precede the target period.
