Abstract: A method for processing fused “underground+ground” data in deep formation exploration includes: collecting underground multi-source data by an underground intelligent probing rod, preprocessing the multi-source data to obtain an original digital signal, storing the original digital signal in an underground memory, obtaining continuous depth data by a ground device; performing high-bitrate and low-bitrate compression on the original digital signal, and modulating compressed signals; driving modulated signals by power, so the modulated signal is transmitted in a drilling stem with cable in a form of a power line carrier and then output, or first transmitted in a first section of the drilling stem with cable, re-collected in a short drill pipe with repeater, re-emitted to a second section of the drilling stem with cable, and then output; when a transmission line is disconnected, synchronizing and fusing data; and finally using fused data and the data output by the transmission line as final output data.

Abstract: A method for aligning a laser point cloud and an image based on deep learning includes: collecting data by using a laser ladar and a camera, to obtain laser point cloud data and a two-dimensional (2D) image respectively; dividing preprocessed point cloud data into triangular meshes to obtain a three-dimensional (3D) mesh model of the point cloud data; determining a relative location relationship between a laser radar and the multi-function camera, and constructing a virtual camera in the 3D mesh model to capture a simulated 2D image at a same location and angle as those of the camera; and aligning, by using a convolution neural network (CNN), the 2D image captured by the camera and the simulated 2D image captured by the virtual camera to generate aligned images that map onto each other.

Abstract: Adjusting an operating frequency of a CPU includes setting the operating frequency for a current operating cycle based on a CPU load in a prior operating cycle and a target CPU load. A current CPU load associated with the current processing cycle is detected. The CPU operating frequency is adjusted to a new operating frequency based on a difference between the target CPU load and the current CPU load. The operating frequency is adjusted based on minimizing the difference between the target CPU load and the detected load. A CPU load error is determined based on the current CPU load and the target CPU load. The target CPU load is adjusted based on the determined CPU load error and a threshold load error. A prediction is generated on whether to perform a new adjustment of the operating frequency of the CPU prior to expiration of a threshold time duration.

Abstract: A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.
