    Abstract: A system and method for detecting input phase loss in an adjustable speed drive (ASD) includes an input unit to detect operating data from the ASD. The operating data includes a DC link current of the ASD. The system also includes a state observer that is adapted to receive the operating data from the input unit and extract a DC link capacitor current of the ASD using the DC link current. The system also includes a controller programmed to compare the extracted DC link capacitor current to a predetermined fault range and generate a fault indication of an input phase loss if the extracted DC link capacitor current is within the predefined fault range. The controller is also programmed to calculate an estimated lifespan of the DC link capacitor based on the extracted DC link capacitor current.

    Abstract: A disturbance, for example, a frequency variation, is generated in at least a portion of the power distribution network. The disturbance may be generated, for example, by an uninterruptible power supply (UPS) or some other component of the power distribution network, such as a switch. At least one node of the network experiencing the disturbance is identified and a topology of the power distribution network is determined responsive to identifying the at least one node. The at least one node may be identified by detecting a voltage-related artifact corresponding to the disturbance. A phase-locked loop (PLL)—based circuit may be used for fast artifact detection. Groups of devices in the network may be identified from the artifacts, and combinatorial optimization techniques may be used to determine connectivity within such groups.

    Abstract: The present invention provides a method of managing a stock replenishment system in a way that explicitly controls the in-stock rate. Also provided by the present invention is a method of managing a collection of stock replenishment systems in a way that the combined in-stock rate of the collection is controlled to a selected value. In addition, the present invention provides a method to set up a collection of stock replenishment systems in replenishment software systems in an identical fashion while controlling the combined in-stock rate. The methods of the present invention use point-of-sale data to determine packages-per-shopper rates, which are used as one of the inputs to statistical models of multiple-day retail sales.

    Abstract: A process for leaching an ore containing sulfidic copper-containing minerals includes carrying out an aerated oxidizing leach of a part of the ore and producing an acidic leach liquor containing ferrous ions, ferric ions, and copper ions in solution. The process also includes carrying out a leach of another part of the ore using the leach liquor under conditions that minimize reactions with a source of iron in the ore and producing a leach liquor containing copper ions in solution. The process further includes recovering copper from the leach liquor.

    Abstract: Several methods and apparatus to single XOR operation weaver reconstruction of a failed drive of a raid are disclosed. A failed drive of the drive group implemented in a WEAVER code with an (n,t,t) layout is determined. A set of scatter/gather lists is produced from a number of the other drives of the drive group. A scatter/gather list is created by modifying a pointer data of the set of scatter/gather lists. An additional scatter/gather list is generated from the set of scatter/gather lists. A single XOR operation is performed on the data segment, the parity segment, the additional data segment and the additional parity segment to form a resulting scatter/gather list including a resulting data segment and a resulting parity segment. The resulting data segment and the resulting parity segment are written as sequenced in the resulting scatter/gather list to a replacement drive.
