Abstract: Embodiments of the present disclosure provide a solution for keyword determination. A method includes: presenting an interface comprising a plurality of information fields associated with an object; in response to detecting completion of input in a first information field among the plurality of information fields, determining at least one candidate keyword for the object based on first information input in the first information field, the first information comprising at least one of: text or visual information; and presenting the at least one candidate keyword for selection into at least one of the plurality of information fields. This solution allows efficient and timely keyword determination while the user is editing or modifying the object information.

Abstract: In general, embodiments relate to a method for managing a network device. The method includes detecting a change of at least one physical port on the network device; and in response to detecting the change, disabling the at least one physical port, wherein disabling the at least one physical port prevents the at least one physical port from being allocated to any logical port on a network processor in the network device.

Abstract: A bridgeless power factor improvement converter is configured with input terminals to which an AC voltage is input, output terminals from which a DC voltage is output, diodes, first and second switches, first and second coils, a pair of series diodes, and a control circuit. When one input terminal has a positive potential relative to the other input terminal, the control circuit performs a switching operation for only the first switch. When the one input terminal has a negative potential relative to the other input terminal, the control circuit performs the switching operation for only the second switch. A capacitor, which is provided independently from the pair of series diodes, is connected to at least one of the pair of series diodes in parallel.
