Abstract: Data is received that characterizes a transaction and includes a plurality of values corresponding to variables. Thereafter, a score is determined for the transaction based on the received data and using a scoring model. The scoring model only uses variables pairs having a divergence residual above a pre-defined threshold. Thereafter, data is provided that characterizes the determined score. Related apparatus, systems, techniques and computer program products are also described.

Abstract: The invention relates to a power grid visualization system and a power grid visualization method based on a three-dimensional geographic information system (GIS) technology. Models to be loaded are divided into different model loading subtasks according to the difference of object types included in a scene to be loaded, and model files are called in parallel from a plurality of subtasks in a multi-thread mode; and meanwhile, on the basis that loading tasks are divided into a plurality of model loading subtasks according to the loaded object types, model files of objects of each type are only read once, moreover, reuse of the model files is not limited to a client loading task, different clients can reuse the read model files, and the characteristics of limited type and relatively consistent specification of power equipment are fully considered, so that rereading of the model files of the same type is avoided.

Abstract: The present invention provides a method and device for treating and analyzing a biological specimen. The biological specimen is introduced into a processing device and treated thermally, mechanically, chemically or any combination thereof within the processing device to alter at least one constitutive characteristic of the biological specimen and to release or create one or more biological indicators from the biological specimen. The biological specimen is further contacted with a treated polymeric material so that at least a portion of the polymeric material binds to the one or more biological indicators.

Abstract: Particular embodiments generally relate to providing risk management. In one embodiment, a first risk is linked to an account group assertion in a data structure. A second risk is linked to a control objective in the data structure. Access to the first risk is granted through the account group's assertion. Access to the second risk is granted through the control objective. Risk management is then performed using the accessed first risk and second risk.

Abstract: In one embodiment, the invention provides a method for repairing a defective storage device in a physical storage-device array having a plurality of storage devices. The method comprises the steps of identifying a disk error associated with the defective storage device; effecting an error recovery pause based on the disk error; processing one or more outstanding data storage or retrieval requests; and generating a new data storage request instructing the physical disk device array having the defective storage device to store valid data associated with the data storage or retrieval request corresponding to the disk device error, whereby the defective storage device is repaired.

Abstract: In one embodiment, the invention provides a method for accessing a physical storage-device array comprising a plurality of storage devices. The method includes (1) obtaining at least one parameter from a profile selected from two or more profiles concurrently defining two or more virtual arrays, each profile defining (i) a different virtual array associated with a corresponding set of storage devices and (ii) a parameter set of one or more parameters used for accessing the virtual array; and (2) generating an instruction, based on the at least one parameter, for accessing, or disallowing access to, information in the virtual array defined by the selected profile, wherein a parameter in each the parameter set defined by each profile indicates whether two or more storage devices in the corresponding virtual array are degraded.

Abstract: When a system detects that a transaction key in the SIM card (18) of a mobile station (36, 38) is non-existent or is no longer valid, the method automatically performs the following steps: generating in the application key server (42) a transaction key; encrypting the transaction key in the application server (42) using a transmission key generated when the SIM card was customized; transmitting the encrypted transition key via the SMS service centre (40) to the mobile station (36, 38); decrypting in the SIM card (18) the encrypted transaction key using the transmission key; and recording the decrypted transaction key in the SIM card storage. Furthermore, the method enables to select among several possible keys one key which corresponds both to a specific application and to a specific service provider.
