Owning to the requirements for longer endurance, larger payloads as well as simpler mechanical structure of tactical UAV, the two-element airfoil technology is introduced.Firstly, the aerodynamic characteristics of five common low-speed airfoils are calculated and compared.The airfoil with good aerodynamic performance after segmentation is selected
Quantum random number generators (QRNG) based on amplified spontaneous emission (ASE) are known to achieve multi-gigabit-per-second rates through high-speed sampling of intensity and phase fluctuations.Two popular implementations of these QRNGs are based on balanced detection of ASE-ASE and ASE-Laser beating.The high QRNG rates reported so far howe
To solve the problems of higher energy consumption and lower intelligence of traditional hard hose travelers, a new hard hose traveler with the function of electric drive and self-propelled is developed in this paper.The operational energy consumption of a reel and a polyethylene tube is an important part of hard-hose traveler energy consumption.In
The cell membrane has gained significant attention as a platform for the development of bio-inspired nanodevices due to its immune-evasive functionalities and copious bio-analogs.This review will examine several uses of cell membranes such as (i) therapeutic delivery carriers with or without substrates (i.e., nanoparticles and artificial polymers)
