Abstract: One or more actuators can be used to provide a substantially continuous level of lumbar support to a seat occupant. An actuator can be operatively positioned relative to a lumbar region of a seat. The actuator can be caused to morph into an activated configuration to support a lumbar region of a seat occupant. The activated configuration of the actuator can be maintained to provide a substantially continuous level of lumbar support.

Abstract: Methods and systems for performing a combinatorial optimization task are provided. The method includes: receiving a first set of data items and a second set of data items; dividing the second set of data items into a first subset and a second subset; generating, based on the first subset, a first set of subset sums, and storing the first set of subset sums as a list; generating, based on the second subset, a second set of subset sums, and storing the second set of subset sums as a hash-map in conjunction with a corresponding hash function; and detecting, based on the first set of data items, the list, and the hash-map, at least one match between a subset sum that corresponds to the second set of data items and a subset sum that corresponds to the first set of data items.

Abstract: The disclosure provides a security analysis method and system based on protocol state, which relates to the technical field of protocol security protection. The method includes the following: a node traversal table is built, the node traversal table is scanned and analyzed according to the protocol trigger sequence rule, a first security evaluation factor of a protocol stack is determined, and a second security evaluation factor of each protocol is determined based on protocol normal application rule, and the trustworthiness degree of the second security factor is determined based on the first security factor, and the second security factor is revised based on the trustworthiness degree, and the security state of the protocol is determined according to the revised second security factor, thus the analysis of the protocol state is realized, and the security of the protocol can be accurately determined.

Abstract: Systems and methods described herein retrieve data from a data store, the data comprising marketing data associated with a plurality of advertising channels disposed in a plurality of geographic units. The systems and methods pre-process the data to derive a pre-processed data set, and hierarchically cluster the pre-processed data set. The systems and methods further derive a reduced multicollinearity data set having one or more clusters based on the hierarchically clustering by reducing a distance metric among geographic units of the plurality of geographic units that are disposed inside the one or more clusters, and analyze the one or more clusters with a model to generate one or more visualizations used to increase an impression impact, increase a carryover, or a combination thereof, in at least one of the plurality of advertising channels.

Abstract: The disclosure provides a method, a device and a computer readable medium for determining the penguin population relating to the technical field of image processing. The method of one embodiment of the disclosure comprises the following steps: firstly acquiring the penguin habitat image detected by the unmanned airborne sensor; and acquiring an interest region with penguins distributing, and a gray value of the interest region from the penguin habitat image; then for any one of gray value: determining a penguin state according to the gray value; finally determining the penguin population according to the penguin state.

Abstract: A feces color-based remote sensing estimation method and apparatus for Antarctic bird population size is disclosed, which comprises: determining a reflectance value range of a mixture of new feces and old feces in a remote sensing image; determining a sample mixture area where the mixture is located, based on the reflectance value range of the mixture in the remote sensing image; classifying the sample mixture area into a plurality of grade areas and determining an area of each grade area based on an obtained reflectance value of the sample mixture area; and generating a one-to-one correspondence between a density of birds of each grade area in the sample mixture area and the each grade area, based on the area of the each grade area and an obtained number of birds in the each grade area.
