Abstract: A downlink bandwidth control method is applicable to a network device including a first queue for first traffic and a second queue for second traffic, and includes: determining whether traffic the network device is receiving meets a predetermined criterion associated with the first traffic; acquiring a total downlink bandwidth between the network device and another network device; and in response to determining that the traffic the network device is receiving meets the predetermined criterion associated with the first traffic, setting an upper bound of a download speed of the second traffic to a decreased value according to the total downlink bandwidth, wherein the decreased value is equal to a portion of the total downlink bandwidth.

Abstract: A control method for a memory device is provided. The control method includes the following steps. Convert multiple input bits on multiple bit-channels into a code word through a polar code transformation. Select a boundary bit-channel among the bit-channels according to a first ranking list for the bit-channels. Identify a target memory cell among the memory cells according to the boundary bit-channel and a generator matrix of the polar code transformation. Decrease a raw bit error rate of the target memory cell.

Abstract: A system and a method for monitoring and controlling the quality of a culture water are provided. The system includes a plurality of smart culture nodes having integrated water quality analyzers, a culture gateway and a terminal host. In the present method, each of the smart culture nodes detects the quality of the culture water through the integrated water quality analyzer thereof and activates corresponding culture equipments to adjust the quality of the culture water. Besides, the terminal host groups the smart culture nodes through the culture gateway and synchronously controls the smart culture nodes in the same group according to a water quality information collected by the smart culture nodes in the same group so as to activate the corresponding culture equipments to adjust the quality of the culture water. Thereby, the quality of the culture water can be efficiently monitored and controlled.
