Title: Online fraud detection dynamic scoring aggregation systems and methods
Inventor: TIBEICA N MARIUS
IPC: G06F21/56
Filed: 2012-09-05
Abstract: In some embodiments, an online fraud prevention system combines the output of several distinct fraud filters, to produce an aggregate score indicative of the likelihood that a surveyed target document (e.g. webpage, email) is fraudulent. Newly implemented fraud filters can be incorporated and ageing fraud filters can be phased out without the need to recalculate individual scores or to renormalize the aggregate fraud score. Every time the output of an individual filter is calculated, the aggregate score is updated in a manner which ensures the aggregate score remains within predetermined bounds defined by a minimum allowable score and a maximum allowable score (e.g., 0 to 100).

Title: Alumina production method
Inventor: SENYUTA ALEKSANDR SERGEEVICH
IPC: C22B21/00
Filed: 2012-07-20
Abstract: The invention relates to metallurgy. In particular, it relates to acidic methods of alumina production, and can be used in the course of processing low-grade aluminium-containing raw materials. This method for producing alumina includes: baking of aluminum-containing raw materials; processing of said materials with hydrochloric acid; aluminum chloride salting-out by saturating the clarified chloride solution with gaseous hydrogen chloride; aluminum chloride calcination to produce aluminum oxide, and; mother liquor pyrohydrolysis, including returning hydrogen chloride to the stages of acidic treatment and salting-out. For improving the quality of alumina and reducing power costs, aluminum chloride ¨ precipitated in the course of salting-out ¨ is treated with aqueous ammonia; the resulting precipitate goes to calcination, and the ammonium chloride solution is mixed with said aluminum-containing raw materials before or during baking; ammonia (released during baking) is dissolved in the water; the resulting aqueous ammonia goes to treat aluminum chloride. The ammonium chloride solution ¨ prior to mixing with the aluminum-containing raw materials ¨ may be subjected to stage-wise evaporation (by means of re-using heating steam.) Ammonium chloride (released during evaporation) can be mixed with the aluminum-containing raw materials.

Abstract: Embodiments of the present invention provide a file processing method and a storage device. In the method, a storage device receives T files that are to be stored in the RAID, and determines a sequence number of a check block in a stripe of the RAID. The storage device repeatedly obtains a data block of the K th file in the T files as the K th data block in the stripe, where a value of K progressively increases from 1 to T, and the value of K is not equal to the sequence number of the check block in the stripe. After computing the check block according to data blocks, the storage device writes, into the T disks, the data blocks and the obtained check block in the stripe. By using the foregoing method, one file can be written into one disk of the RAID while ensuring security of file storage.

Abstract: A coated component for use in a fluid energy device includes a coating system with multiple layers of coating material, including a soft material such as a polymer coated over a hard material such as a metal. The fluid energy device can be a fluid motor or fluid pump, and the coated component can be a rotor or a stator. The hard and soft materials may be interlocked with each other and/or with an interposed porous layer, The presence of the soft material can reduce or eliminate the need for meticulous polishing operations typically required with as-applied hard materials while improving the longevity of mating fluid energy device components. The mating components are exposed only to the soft material in the initial stages of operation, after which the soft material wears away to gradually expose the mating components to the hard material in a less abrasive manner.

Abstract: Disclosed is a roller press for dewatering vegetable feed material. A base roller is rotated by a motor at a speed required to pick up the feed material in a mat formed from a feed trough and compress the mat forming a loose mat as a scraper removes the mat from the roller. A first perforated roller rotates by a motor at a rotational speed to collect the loose mat and compress it forming a first compressed mat as a first perforated roller scraper removes the mat from the roller. Separate sensors generate signals indicative of the thickness of the feed solids mat, the loose mat, and of the first compressed mat. A  control system selects each of the base roller rotational speed and first perforated roller rotational speed basing those selections upon a first thickness signal, a second thickness signal, and a third thickness signal.
