The modulation transfer function (MTF) quantitatively describes the ability of an optical or imaging system to reproduce contrast at various spatial frequencies.The ISO 12233 edge-based method adopted diagonal MTF measurement for sampled imaging systems by analyzing the gradient of a slanted edge captured by the system and estimating MTF as a funct
MOOCs (massive open online courses) are popular distance courses for which anyone can sign up Collections online with no limits on the number of participants.Moreover, artificial intelligence is a combination of algorithms for the development of human and rational capabilities by machines.This article presents a quantitative study with a sample of
Abstract Background The reading man flap is a novel technique in human medicine for the closure of cutaneous circular defects.To the best of our knowledge, no recent clinical studies have described this procedure in small animals.Case presentation In this case series, we present Collections four dogs in which neoplasms were reconstructed using the
Different discharge processes of triggered lightning can radiate electromagnetic signals with different frequency bands.During the triggered-lightning experiment conducted at the Field Experiment Base on Lightning Sciences of China Meteorological Administration (CMA-FEBLS), three magnetic field (B-field) antennas with different frequency responses
The combination of multi-agent technology and reinforcement learning methods has been recognized as an effective way which is used in path planning-based crowd simulation.However, the existing solution is still not satisfactory due to the problem in the mutual influence of agents.Therefore, an improved multi-agent reinforcement learning method (IMA
