Abstract: A method and a circuit for extracting current-voltage characteristics employ two pulse signals with different duty cycles into a device to be measured in order to extracting current-voltage characteristics of the device to be measured. The present invention may reduce the self-heating effect of the device to be measured and increase the measurable range of the device to be measured.

Abstract: A method for controlling read velocity in a disk device is provided. When reading data on the disc, the method first reads each SYNC of blocks to form an ECC code, read data to decode, and checks and corrects decoded data to generate decoded errors. The type of decoded errors are classified and counted to form reference parameters of a rule base. A fuzzy engine checks if the counting number exceeds the threshold of the parameter, and executes the operation of the rule to control read velocity and enhance the data transfer rate in the disk device.

Abstract: A computer-implemented method for routing shipments according to criticality includes accessing an initial solution to an optimization problem of routing multiple shipments to multiple locations using multiple vehicles, the initial solution including multiple loads such that each shipment is routed within exactly one load and a global cost across all loads is minimized, the initial solution being generated independent of the criticality of the shipments. Into each of one or more critical loads in a current solution, one or more non-critical shipments are inserted that are within a neighborhood of the critical load, a critical load being a load containing at least one critical shipment.
