Litchi is often harvested by clamping and cutting the branches, which are small and can easily be damaged by the picking robot.Therefore, the detection of litchi branches is particularly significant.In this article, an fully convolutional neural network-based semantic segmentation algorithm is proposed to semantically segment the litchi branches.Fi

The annual cumulative quantity of high and medium alloy steel scrap has exceeded 10 million tons.Using the traditional smelting process Brake Rotor involving electric arc refining in a smelting furnace for these scraps causes high percentages of alloy losses, which decreases the value of the alloy steel scrap and poses environmental threats.Existin

To use urban underground space more efficiently is a research hotspot of urban underground development.Compared with conventional circular tunnels, quasirectangular tunnels have the characteristics of larger space utilization and higher economic benefits, gradually used in urban rail engineering in recent years.But the ground disturbance induced by

Abstract In the realm of prognosticating the remaining useful life (RUL) of pivotal components, such as aircraft engines, a prevalent challenge persists where the available historical life data often proves insufficient.This insufficiency engenders obstacles such as impediments in performance degradation feature extraction, inadequacies in capturin

OBJECTIVES: Human immunodeficiency virus type 1 (HIV-1) infection has been detected in all provinces of China.Although epidemiological and phylogenetic studies have been conducted in many regions, such analyses are lacking from Jilin province in northeastern Sprocket China.METHOD: Epidemiological and phylogenetic analyses, as well as detection of d
