  • Patent number: 11775438
    Abstract: System identifies multiple data blocks in workload stored in slow access persistent storage, data blocks copied to fast access persistent storage, and, after speed of accessing workload satisfies threshold, copied data blocks that remained in fast access persistent storage. System annotates some remaining data blocks with cache label and derives features for some data blocks in workload, based on corresponding bits set and/or time stamp. System uses cache labels and features for some data blocks in workload to train machine-learning model to predict which data blocks in workload will remain in fast access persistent storage after workload access satisfies threshold. System derives features for data block requested from production workload.

  • Patent number: 11465510
    Abstract: A magnetic suspension bogie, the bogie comprising a upper frame located at the upper portion, two lower frames located at the lower portion, a suspension device and a track sensing device, wherein the upper frame and the lower frames are hinged and connected by means of a connecting device. By means of using a bearing hinge structure to connect the upper frame and the lower frames, it is not necessary to specially provide a separate steering mechanism; thus, a plurality of functions are comprised, while the structure is at the same time simplified. The present invention also relates to is a magnetic suspension train.

  • Publication number: 20210163047
    Abstract: A method for train suspension control by means of multiple air springs includes: receiving a vehicle load pressure; and controlling height adjustment valves according to the vehicle load pressure to adjust the pressure of a first air spring set, a second air spring set and/or a third air spring set. Three height adjustment valves are provided, and the three height adjustment valves form a triangular structure. Each of the first air spring set, the second air spring set and the third air spring set comprises a plurality of individual air springs, and all the individual air springs in each of the air spring sets are correspondingly connected to the same height adjustment valve. A system for train suspension control by means of multiple air springs and a train are further provided.

  • Patent number: 10745036
    Abstract: A bogie, including a frame (1) and a bolster (2), the frame (1) including two parallel side beams (11), and a cross beam (12) coupled to the middle of the side beams (11), wherein a primary suspension is arranged between an end of the side beam (11) and an axle box (31), a secondary suspension is arranged between the below of the bolster (2) and the cross beam (12), and a tertiary suspension coupled to a vehicle body is arranged above the bolster (2). By including a bolster and an extra suspension on the basis of the conventional two suspensions, the disclosed bogie can achieve separation of the functions, so that the tertiary suspension only handles the transverse displacement, and the secondary suspension only handles the rotation, thereby further increasing the relative displacement and rotation angle between the vehicle body and the bogie when the vehicle negotiates a curve.

  • Patent number: 10738028
    Abstract: Disclosed are the anti-bacterial activity and the anti-tumor activity of a class of new spiro three-membered ring and spiro five-membered ring peptide deformylase inhibitor. The spiro three-membered ring and spiro five-membered ring peptide deformylase inhibitor of the present invention, as a class of new anti-bacterial agent, are effective against many antibiotic-resistant Gram-positive strains by inhibiting the activity of the peptide deformylase required in the synthesis of bacterial proteins, and do not affect the synthetic process of the main proteins of the human body, thus selectively killing bacteria.

  • Publication number: 20190095400
    Abstract: A Gaussian similarity matrix is computed between observation vectors. An inverse Gaussian similarity matrix is computed from the Gaussian similarity matrix. A row sum vector is computed that includes a row sum value computed from each row of the inverse Gaussian similarity matrix. (a) A new observation vector is selected. (b) An acceptance value is computed for the new observation vector using the set of boundary support vectors, the row sum vector, and the new observation vector. (c) (a) and (b) are repeated when the computed acceptance value is less than or equal to zero. (d) An incremental vector is computed from the inverse Gaussian similarity matrix and the new observation vector when the computed acceptance value is greater than zero. (e) the selected new observation vector is output as an outlier observation vector when a maximum value of the incremental vector is less than a first predefined tolerance value.
