A system and method for hot-plug/remove of a new component in a running communication fabric, such as a PCIe fabric, are provided. With the system and method, the addition of a new component in the fabric is detected and an event is sent to a multiple root fabric configuration manager. The multiple root fabric configuration manager gathers information about the new component and updates its I/O component tree structure in its configuration data structure to include the new component. The new component may then be utilized via the updated configuration data structure. When a component is to be removed, the multiple root fabric configuration manager receives an event indicating the component to be removed, determines which branches of the tree structure are affected by the removal, and updates its configuration data structure accordingly to remove the component and its associated components from the virtual plane of the removed component.

A computer program product and system are disclosed for parsing a problem SQL statement into query clauses, formatting these query clauses into a hierarchical tree structure, generating performance statistics for clauses that have associated performance statistics and displaying the formatted SQL statement with each clause contained on a separate display line annotated with its corresponding associated performance statistics on the same display line and with the hierarchical tree structure represented by indention levels of the separate display lines.

The invention discloses a Chinese AC (Aho-Corasick) automaton working method based on a keyword dictionary tree structure. The method comprises the following steps: obtaining all keywords, coding all keywords, and arranging all keywords according to a character sequence of the keyword codes; establishing a dictionary tree, and adding all keywords into the dictionary tree according to the character arrangement sequence; adding a prefix pointer for each non-imaginary root node in the dictionary tree; adding a failure pointer into each non-imaginary root node in the dictionary tree; and obtaining an article to be detected, and inquiring and recording all keywords in the article to be detected according to the dictionary tree which comprises the prefix pointer and an error pointer. Through a technical scheme that the keywords are arranged and added into the dictionary tree in sequence, the keywords with the same prefix can be effectively arranged on adjacent positions in the dictionary tree, so that an information amount for the node to inquire positions where the subnodes of the node are positioned can be drastically compressed, and the work occupation space of the Chinese AC automaton is reduced.

The invention discloses a rapid multi-scale super-pixel segmentation method for a synthetic aperture radar image. The method comprises the following steps: measuring the final similarity of two pixelsin combination with backscattering gray similarity, edge information similarity and homogeneity similarity; performing graph structure representation on the SAR image; constructing a minimum spanningtree for the SAR image; sAR image fast multi-scale super-pixel segmentation is achieved based on the minimum spanning tree, a super-pixel segmentation boundary is obtained based on a segmentation result, and an SAR image segmentation result is generated. According to the invention, any number of superpixels with a tree structure can be generated immediately, so that superpixel results of different levels can be segmented. According to the multi-scale super-pixel segmentation method, image boundaries can be well kept, the good image local detail keeping capacity is achieved, the segmentation result of any scale can be generated for the SAR image in real time, target information of different sizes can be easily obtained, and the execution efficiency is remarkably improved.

The invention discloses a data updating method and electronic equipment, which are used for automatically and synchronously updating auxiliary data for realizing different functions under the condition that the content of a target object is updated. The method comprises the steps that under the condition that a target object is updated, acquiring the updated target object; generating a first treestructure according to the updated target object; comparing the first tree structure with a second tree structure corresponding to a target object before updating to obtain elements changed after thetarget object is updated; and updating preset data according to the changed elements. By adopting the method provided by the invention, under the condition that the target object is updated, the firsttree structure can be generated according to the updated target object; and the first tree structure is compared with a second tree structure corresponding to the target object before updating, so that the changed element of the target object after updating can be obtained, and the preset data are updated based on the changed element.

The invention discloses a data acquisition and analysis system based on a wireless body area network and a low-energy-consumption data fusion privacy protection algorithm. The system comprises: a dataacquisition node which is electrically connected with data monitoring equipment and is used for receiving data of the monitoring equipment; a data transmission node which is electrically connected with the data acquisition node and is used for carrying out noise filtering and first-level data fusion calculation; and a data analysis node which is in signal connection with the data transmission node and is used for carrying out final data fusion analysis calculation. A data fusion model of a tree structure is used, on the basis of a data fusion function structure expression, a data fusion function based on unequal time intervals is provided, and a random key distribution strategy is adopted for data encryption and decryption; the method has the characteristics of small data communication traffic, high privacy protection, high accuracy and low energy consumption.

The invention relates to a yellow peach planting method. During the planting process, a crown is pruned into a horizontal three-fork-shaped tree body structure with one main branch and two side branches at two symmetrical sides of the main branch; and the side branches between every two adjacent plants correspond to the main branch. According to the planting method provided by the invention, through reasonably managing and pruning branches and leaves, fruit trees forming a forest are of horizontal three-fork-shaped tree body structures, and the side branches between every two adjacent plants correspond to the main branch, so that compared with an existing fruit-bearing forest structure, a plantation field is reasonably utilized, a larger lighting and forest operation space is formed, the field planting spacing can be shortened, the quantity of plants per mu can be increased by 30 to 50 percent compared with an existing planting method, and the acre yield is remarkably increased compared with the acre yield of the existing planting method. A fruit garden forming the forest is convenient to manage and beneficial to the launching of the work such as conventional nutrient and water management and pest control, so that the yield and the quality of yellow peaches are improved, and the aims of high yield and high quality can be continuously maintained.
