In order to investigate the dynamic characteristics of blunt aircraft mounted with aerospikes and aerodisks in large-amplitude force-pitching, the Roe spatial scheme and the lower-upper symmetric Gauss-Seidel (LU-SGS) method with dual time step are employed for Collagen discretization of unsteady Navier-Stokes (N-S) equations.A parametric investiga
The invention of lacquer technology is significant in history as the first evidence of the use of an organic substance in creating durable coloured Enamel Pin objects.By focusing on the evidence from the Jomon Period, Japan, this article clarifies the nature of complex technology and knowledge required for lacquer production, presents how lacquer t
Accurate retrieval of column-averaged dry-air mole fraction of methane (XCH4) in the atmosphere is important for greenhouse gas emission management.Traditional XCH4 retrieval methods are complex, while machine learning can be used to model nonlinear relationships by analyzing large datasets, providing an efficient alternative.This study proposes an
To satisfy the demands of civil aviation organizations and other users of satellite navigation systems for high-precision and high-integrity service performance, many countries and regions have established satellite-based augmentation systems (SBAS) referring to the Radio Technical Commission for Aeronautics (RTCA) service standards and agreements.
The design of multifunctional magnetic nanoparticles (NPs) that can generate and monitor heat release in real-time during thermal therapy is a major challenge in nanomedicine.In this work, a trimodal system that combines FETs magnetic hyperthermia (MH), photothermal therapy (PT) and luminescence nano-thermometry (LT) has been set up in a single pla
