Of the many direct numerical methods, the pseudospectral method serves as an effective tool to solve the reentry trajectory optimization for hypersonic vehicles.However, the traditional pseudospectral method is time-consuming due to large number of discretization points.For the purpose of autonomous and adaptive reentry guidance, the Magnetic produ
Abstract Solar geoengineering maintains a vocal presence as a stop-gap measure in assessments of climate and sustainability action.In this paper, we map prospective benefits and risks, and corresponding governance approaches, regarding Coil Covers three major proposals for solar geoengineering (stratospheric aerosol injection, marine cloud brighten
Ultrasonic treatment (UST), more precisely, cavitation and acoustic streaming, of liquid light metal alloys is a AEG DLE0431M Designer 50cm Island Hood - Stainless Steel very promising technology for achieving grain and structure refinement, and therefore, better mechanical properties.The possibility of predicting these process phenomena is an impo
Abstract Background Gene named entity classification and recognition are crucial preliminary steps of text mining in biomedical literature.Machine learning based methods have been used in this area with great success.In most state-of-the-art systems, elaborately designed lexical features, such as words, n-grams, and morphology patterns, have played
