Abstract: Systems, computer program products, and methods are described herein for large scale data extraction and processing. The method includes receiving a transmission request. The transmission request indicates two or more accounts for which one or more account statements are to be retrieved. The method also includes selecting a first retrieval set of the two or more accounts. A first retrieval set size of the first retrieval set is based on a first expected network capacity. The method further includes causing a retrieval of one or more account statements associated with first retrieval set. The method still further includes selecting a second retrieval set of the two or more accounts. A second retrieval set size of the second retrieval set is based on a second expected network capacity. The method includes causing a retrieval of one or more account statements associated with the second retrieval set.

Abstract: A method and system for detecting structural performance of fire retardant disc includes the steps of obtaining passage structural information characterizing a structural feature of each passage in a fire retardant disc to be detected, analyzing said passage structural information and measuring a key feature size of each passage, statistically analyzing feature size distribution of each passage according to said key feature size, and determining a structural uniformity state of said fire retardant disc to be detected based on statistical result. The method is able to overcome the disadvantage of manual detection in the structural performance of the fire retardant disc, and effectively detect and assess the structural performance of the fire retardant disc in different use conditions.

Abstract: A flame arrester, has a housing having an inlet and an outlet, and a flame retardant core arranged within the housing. Arranged within the flame arrester housing between the flame retardant core and the inlet is a flame arresting mechanism for preventing flames from directly impacting a central zone of the flame retardant core. The flame arresting mechanism may include a flame retardant barrel and a flame retardant plate assembly disposed within the flame arrester housing.

Abstract: A method for preparing a platinum-indium cluster catalyst for a fuel cell, the method including steps of: obtaining a carbon powder, dispersing the carbon powder in a strong oxidizing solution, and performing high-temperature hydrothermal treatment to obtain an activated carbon powder; obtaining a mixed alcohol solution comprising a platinum precursor and an indium precursor; dispersing the activated carbon powder in the mixed alcohol solution, and heat treating the mixed alcohol solution to volatilize an alcohol solvent to obtain a mixed powder; and performing high-temperature treatment on the mixed powder under a mixed gas atmosphere of hydrogen and argon, to yield a platinum-indium cluster catalyst for a fuel cell.

Abstract: A thin and cost-effective bi-directional loudspeaker which can reproduce high quality sound toward contrary directions simultaneously, arranged from bottom to the top, consists of a frame (2), a U-yoke (3), a first magnet (4), a washer (5), a copper cap (6), a second magnet (7), a voice coil (8), a diaphragm (9), a spacer (12), a spider (15), a dust cap (18) and a connector (1) disposed on lateral side of the frame (2). Said loudspeaker is characterized in that: said diaphragm (9) is in a cone shape whose an inner edge (10) of said apex is fixed with top of said voice coil (8). A periphery (16) of the spider (15) is fixed with an upper edge (14) of the supporting ring (12) and a bottom edge (13) thereof is fixed with an exterior (11) of the diaphragm (9). Said spider (15), spacer (12) and diaphragm (9) are coupled by adhesive and fixed on top of said frame (2).
