    Abstract: A reducing dross method of lead-free solder includes the steps of: producing master alloy of reducing dross which comprises Sn and 0.1 to 0.8 wt % P; analyzing the percentage of P of the lead-free solder to be modified, in order to reach 0.008 to 0.015 wt % P in the lead-free solder, adding the master alloy into the lead-free solder with the percentage of P less than 0.008 wt % or no P; then sampling the lead-free solder at regular intervals to determine the percentage and the percentage loss of P, if the percentage of P being less than a given value from 0.008 to 0.015 wt %, adding the master alloy to keep the percentage of P as 0.008 to 0.015 wt %.

    Abstract: Embodiments are directed to promptly reestablishing communication between nodes in a dynamic computer network and dynamically maintaining an address list in an unstable network. A computer system sends a message to other message queuing nodes in a network, where each node in the message queuing network includes a corresponding persistent unique global identifier. The computer system maintains a list of unique global identifiers and the current network addresses of those network nodes from which the message queuing node has received a message or to which the message queuing node has sent a message. The computer system goes offline for a period of time and upon coming back online, sends an announcement message to each node maintained in the list indicating that the message queuing node is ready for communication in the message queuing network, where each message includes the destination node's globally unique identifier and the node's current network address.

    Abstract: A model for automated item generator of the graphic intelligence test solves the tremendous time consuming problem for manually devising the graph intelligence item. At the same time, the invention can automated generate more complicated, more transformations and better layout graph for intelligence test, which are hard to predict. The model utilizes the 12 branch tree as the expressing pattern of matrix graph item, and 8 branch trees as the expressing pattern of series graph item. The automated generating item methods have been presented, and the difficulty of the item has also been validated with the similarity of the optional answers and difficulties of the rules and complexity of the sub-graph. The best feature of the model is that a big amount of the graph item for intelligence test can be generated at one time by the computer, instead of manually devising the matrix graph or series graph for intelligence test. With the model, the online intelligence test platform can update the test database automatically, thus the intelligence and the ability of the examinee can be evaluated breaking through the barrier of the language, culture and education background.
