The assignment problem of the unmanned aerial vehicle (UAV) cluster to target group is analyzed based on the Holon theory. The formation process of the air fleet Holon alliance is the process of the unordered UAV cluster form into columns satisfying the tasks demand. The total task of the target group...

In this paper, the problem of path planning existing target movement in the flight is studied. Firstly, according to the terrain threat, the threat field is created by using the Voronoi diagram method, and the total cost of the track is established. Then, the problem of the traditional path planning...

The Programmed Cell Death 1 (PD-1)/Programmed Death Ligand 1 (PD-L1) Immune Checkpoint Inhibitors (ICIs), have become a hot spot in the field of cancer research and treatment, and bring new hope to patients with advanced tumors. But, in addition to enhancing the anti-tumor effect of T cells, PD-1/PD-L1...

This paper adopts the melt blending method for organic silicon resin/nano Al2O3 and PF. The organic silicon resin in the blending resin cures and forms interpenetrating network structures to improve the heat resistance of PF plastics. TG, DSC and FESEM analysis characterize the changes in heat resistance...

Compared with conventional path planning method, the path planning for carrier based UAVs has its own characteristics, especially in its return section. Firstly, the fuel carried with the UAV is limited, so that the UAV is expected to return to the carrier as soon as possible after the task is finished....

Abstract. Objective: To observe and analyze the application value in clinical diagnosis of the diabetes patients with blood lipid inspection. Methods: From June 2013 to June 2014 we select 50 patients with diabetes and 50 healthy people in physical examination as the research object, they can be divided...

The adsorption and binding mechanisms of chloride ion in sea sand mortars were investigated through measuring the water-soluble chloride ion content in this paper. In addition,the microstructure of Friedel's salt were characterized by three approaches : X-ray diffraction (XRD), thermal analysis method...

This paper describes the workflow and results for Particle Size Distribution (PSD) analysis using UAV photogrammetry for waste rockfill materials. A methodology for digital detection and statistical measurement of PSD derived from UAV-SfM photogrammetry is presented. The comparative results between field...

Photocatalysis is a green technology that plays a vital role in achieving sustainable development goals and ensuring a clean environment. Metal oxide materials, in particular, have gained tremendous attention for their versatility in fields such as catalysis, semiconductors, ceramics, sensors, and energy...

In recent years, with the rapid development of society, the utilization rate of land and resources has been significantly improved. In order to achieve stable use and reduce loss, relevant personnel need to actively carry out planning and design, and gradually expand the scope of surveying and mapping....

Combining Unmanned Aerial Vehicles (UAVs) with thermal infrared remote sensing provides a rapid, low-cost, and convenient method for measuring crop canopy temperature, which can be used to infer plant water status. This study utilized UAV remote sensing to capture thermal images of tobacco plants. Through...

Sepsis is a life-threatening organ dysfunction caused by a deregulated host response to infection, and is the most common cause of death in the intensive care unit. Although the pathogenesis of sepsis has made substantial progress, the current clinical treatment of sepsis is basically symptomatic treatment,...

Data link system, as important guarantee for unmanned aerial vehicle equipment to complete its battlefield function, its anti-electromagnetic pulse capacity interference directly affect the safety of airborne communications. Strong electromagnetic pulse has become an important source of electromagnetic...

This paper according to the small UAV structure characteristics, the taxiing control structure and control law design are studied and proposed front wheel and rudder deviation control scheme and control structure, analysis, including the front landing gear, pavement condition, brake system, wind and...

The control problems of quad-rotor flight such as under-actuated control, strong coupling were analyzed. With a simplified dynamic model of quad-rotor based on Newton - Euler equation, a double-loop PID controller which consists of the inner attitude control and out position control. According to the...

Key problems in view of the urgent long-endurance uav, the research of the application of bionics to no one wing design. With the wings of a certain unmanned aerial vehicle as the research object, is good at gliding gull for bionic prototype. Design imitation airfoil seagull flat wings and wing tip winglet...

Perovskite-type cube structure LaMnO3 nanofibers of approximately 50~100 nm in diameter were synthesized via Sol-Gel processing and electrospinning technology after calcined at 900 by using polyvinypyrrolidone (10 wt %PVP) as complexing agents. The nanofibers was characterized by means of scanning electron...

In recent years, Unmanned Aerial Vehicle(UAV) is widely used for power lines patrol. While it's more efficient than manually patrolling, the UAV may easily collide with power lines. So measures must be taken to detect the distance between UAV and power lines. This paper presents a real time power line...
