Most birds and many insects use periodic wing motion to propel themselves and maneuver. Most conventional flying machines are propelled by rotating machinery, achieve lift through rotating or fixed wings, and are controlled through the production of steady aerodynamic forces produced by rotors or movable wings. Many of the first powered flapping-wing micro air vehicles (MAVs) effectively replac...

Nationwide monitoring of organochlorine pesticides in wings of more than 24,000 mallards and black ducks bagged during the 1965 and 1966 hunting seasons showed DDE to be the predominant residue, followed in order by DDT, DDD, dieldrin, and heptachlor epoxide. Residues were generally highest in wings from the Atlantic and Pacific Flyways, and lowest in the Central Flyway. DDE was reported for ev...

To study the optimal design of Wave Glider parameters in wave environment Northwest Pacific Ocean, North Indian and South China Sea, average velocity a was taken as evaluation criterion. reanalysis data from ERA5 were used to classify mean height period into five types by K-means clustering method. In addition, dynamic model simulate influence umbilical length, airfoil, maximum limited angle on...

Without inspirations, writing may be a frustrating task for most people. In this study, we designed and implemented WINGS, a Chinese input method extended on IBus-Pinyin with intelligent writing assistance. In addition to supporting common Chinese input, WINGS mainly attempts to spark users’ inspirations by recommending both word level and sentence level writing suggestions. The main strategies...
