Variation in food stoichiometry affects individual performance and population dynamics, but it is also likely that species with different life histories should differ LADIES JACKETS SUIT in their sensitivity to food stoichiometry.To address this question, we investigated the ability of the three nettle-feeding butterflies (Aglais urticae, Polygonia
Recover the abnormal positioning, velocity and timing services caused by BDS satellite orbital maneuvers
Abstract The BeiDou Navigation Satellite System (BDS) provides global Positioning, Velocity, And Timing (PVT) services that are widely used in various areas.The BDS satellites frequently need the orbit maneuvers due to various perturbations to keep satellites in their Logic ICs designed positions.During these maneuvers, PVT services may be abnormal
A Service-Oriented Remanufacturing Framework With Recovery Timing Prediction Based on Remote Condition Monitoring
Remanufacturing is generally regarded as a key technology to implement cleaner production.However, in traditional remanufacturing, scrap products are recycled and remanufactured after their performance declines sharply.This passive approach easily arises many problems such as increases of remanufacturing cost, unstable product quality, and unsatisf
