Disclosed are a method and a device for adjusting screen locking time, and an electronic terminal. Time interval values T1, T2, . . . , and TN between screen locking and screen unlocking for consecutive N times are acquired, and when it is determined that the acquired time interval values T1, T2, . . . , and TN are all in a preset threshold range, a current screen locking time value is updated into the sum of the current screen locking time value and a preset time delay value. In the disclosure, a usage situation in which the terminal automatically locks the screen and a user unlocks the screen is monitored in real time, and according to the time intervals between screen locking and screen unlocking for consecutive N times, it is determined whether the current screen locking time is appropriate in the current usage environment and situation. When the determining result is that the current screen locking time is inappropriate, the current screen locking time value is automatically updated into the current screen locking time value plus the preset time delay value, so as to achieve the objective of dynamically adjusting the screen locking time according to the current usage environment and situation, thereby effectively reducing the unlocking operations and screen locking settings of the user and improving satisfaction in the user experience.

A web page evaluation technique includes obtaining a plurality of web pages with the same or approximately the same content. Further, a plurality of generation times and a plurality of first evaluation values that correspond to respective ones of the plurality of web pages are determined. A web page among the plurality of web pages that has the earliest generation time is identified. A second evaluation value of the identified web page is determined according to the plurality of first evaluation values. The second evaluation value can be used to indicate a ranking of the identified web page.

Described are techniques to use adaptive learning to control bandwidth or rate of transmission of a computer on a network. Congestion observations such as packet delay and packet loss are used to compute a congestion signal. The congestion signal is correlated with information about actual congestion on the network, and the transmission rate is adjusted according to the degree of correlation. Transmission rate may not adjust when packet delay or packet loss is not strongly correlated with actual congestion. The congestion signal is adaptively learned. For instance, the relative effects of loss and delay on the congestion signal may change over time. Moreover, an operating congestion level may be minimized by adaptive adjustment.

A centrifugal compressor for compressing a fluid comprises a compressor wheel having a plurality of circumferentially spaced blades, and a compressor housing in which the compressor wheel is mounted. The compressor housing includes an inlet duct through which the fluid enters in an axial direction and is led by the inlet duct into the compressor wheel, and a wheel shroud located radially adjacent the tips of the blades. A bleed port is defined in the wheel shroud at a location intermediate the leading and trailing edges of the blades for bleeding off a bleed portion of the fluid being compressed by the compressor wheel. A converging injection nozzle is defined in the duct wall upstream of the leading edges of the blades for injecting the bleed portion of the fluid back into the main fluid flow stream approaching the compressor wheel.

The present invention relates to a trifunctional catalyst used in catalytic cracking device in petroleum refining industry and a method for preparing the same. The trifunctional catalyst of the invention comprises absorbent, cerium dioxide and vanadium pentoxide acting as oxidative catalyst and cerium oxyfluoride acting as structural promoter. The oxidative catalyst and structural promoter are dispersed over the absorbent. The absorbent is spinel-based composite oxides having a general formula of MgAl2-xFexO4.yMgO, where the x is 0.01-0.5 and y is 0.2-1.2. In the trifunctional catalyst, the raw material for forming the chemical compound containing rare-earth cerium is hamartite powder. The method for preparing the trifunctional catalyst of the invention is shown as follows: the components relating to the preparation of the finished product are dissolved or dispersed into liquid materials; then the trifunctional catalyst is obtained after the mixing, drying and calcining of such liquid materials. The trifunctional catalyst of the invention is used for highly efficient absorption and desorption of sulfoxides contained in the catalytic cracking flue gas regenerated in the process of petroleum refining, the combustion promoting of carbon monoxide and the reduction of nitrogen oxides. Furthermore, the method for preparing such trifunctional catalyst is featured for its lower cost.

A turbocharger system having a compressor housing containing a rotating compressor wheel with a plurality of impellers that define an impeller passageway from an inducer to an exducer. The compressor housing includes an annular upstream housing-portion forming an upstream shroud-wall, and a downstream housing-portion forming a downstream shroud-wall. The a rib supports the upstream housing-portion with respect to the downstream housing-portion such that they are respectively disposed to form an annular bypass port into the impeller passageway between the upstream and downstream shroud-walls. The rib extends along a non-axial path within the bypass passageway.
