Abstract: Techniques for monitoring particulate matter (PM) mass concentration using relatively low cost devices are described. A computer-implemented method comprises determining, by a device operatively coupled to a processor, relationships between: first PM mass data determined by a monitor station device for a first atmospheric area over a period of time; first PM count data determined by a reference PM count device for the first atmospheric area over the period of time; and first conditional information comprising first values for defined conditional parameters, wherein the first values are associated with the first atmospheric area over the period of time. The method further includes generating an initial conversion model based on the relationships, wherein the conversion model converts a PM count to a PM mass based on one or more conditional parameters of the defined conditional parameters and features for updating the conversion model.

Abstract: A method, system and computer program product for accelerating a deep neural network (DNN) in a field-programmable gate array (FPGA) are disclosed. The method includes receiving a DNN net file and weights, converting the received DNN net file to one or more source files, generating an executable FPGA bit file using the one or more source files, and downloading the executable FPGA bit file from the DNN conversion platform to the FPGA. Converting of the received DNN net file and the weights to the one or more source files can further include analyzing the DNN net file to identify a plurality of neural layers, decomposing one or more neural layers of the plurality of neural layers to one or more operation blocks, instantiating the one or more source files, based on the one or more operation blocks.

Abstract: Methods and systems for producing one or more alkanes from biomass by hydrodeoxygenation are disclosed. Biomass may be converted to one or more alkanes by heating the biomass with a catalyst mixture that includes a noble metal and at least one of a transition metal and derivative thereof. The catalyst mixture may further include a solid acid. Heating may be performed at a single temperature and pressure.

Abstract: Synchronization method and apparatus for a wireless wide band system in an interference environment. The method includes: obtaining interference information of a network; selecting at least one channel based at least in part on the interference information; and transmitting resource information through the at least one channel, wherein the resource information indicates a resource allocation determined at least in part on the interference information; and wherein a position of the at least one channel is indicated by a synchronization sequence. The present invention also provides another method and apparatus for synchronization.

Abstract: A lower lockpin rotation shaft assembly includes a lower lockpin rotation shaft body, an outer end portion thereof having a first coupler lifting bar hole, an intermediate portion thereof having a connecting key; and a lower lockpin rotation shaft bush, an outer end portion of the lower lockpin rotation shaft bush having a second coupler lifting bar hole, and an inner end portion of the lower lockpin rotation shaft bush being operatively connected to an inner end portion of the lower lockpin rotation shaft body. Further, the present invention further provides a double-side operating coupler and a coupler draft gear having the above lower lockpin rotation shaft assembly. The coupler draft gear further includes two coupler lifting bars and two coupler lifting bar seats.

Abstract: A lower locking pin body for the hinge joint between a lower locking pin and a lower locking pin hook has a suspending hole of a coupler lock lifter to facilitate it rotating surrounding the lower locking pin hook under the effect of the hole. There are two coupler suspending holes which are respectively arranged on each side ends of the lower locking pin body to facilitate the workers opening the coupler on either side of a car. A two-side operating coupler with above said lower lock pin body and a draft gear are provided, wherein the draft gear also includes two lock lifters and two lock lifter seats. The lock lifters are mounted into a key-shaped hole of the lock lifter seats, and the lock lifter has a limiting segment on the matched position. Two hook head ends of the lock lifters pass respectively out from the key-shaped holes of the coupler lock lifter seats and hang with the coupler lock lifter suspension hole of the two-side operating coupler.
