Vor einem Tag · Jacqueline " Jackie " Lee Kennedy Onassis ( née Bouvier / ˈbuːvieɪ /; July 28, 1929 – May 19, 1994) was an American writer, book editor, and socialite who served as the first lady of the United States from 1961 to 1963, as the wife of former president John F. Kennedy. A popular first lady, she endeared herself to the American public with ...
Vor 10 Stunden · We show that each connected group scheme of finite type over an arbitrary ground field is isomorphic to the component of the identity inside the automorphism group scheme of some projective, geometrically integral scheme. The main ingredients are embeddings into smooth group schemes, equivariant completions, blow-ups of orbit closures, Fitting ideals for Kähler differentials, and Blanchard ...
Vor 10 Stunden · Newton had almost left out the perturbations to planetary motion Footnote 60: regarding problems of celestial mechanics, Pierre-Simon Laplace (1749–1827) and Joseph-Louis Lagrange (1736–1813) Footnote 61 are the first to tackle the problem laying the foundations of the perturbation theory. Remaining in the field of mathematical physics, Lagrange and later William R. Hamilton (1805–1865 ...
Vor 10 Stunden · In electrochemical energy storage devices, the interface between the electrode and the electrolyte plays a crucial role. A solid electrolyte interphase (SEI) is formed on the electrode surface due to spontaneous decomposition of the electrolyte, which in turn controls the dynamics of ion migration during charge and discharge cycles. However, the dynamic nature of the SEI means that its ...
Vor 10 Stunden · This paper proposes an operation modal analysis (OMA)-based approach to obtain a transformer’s mechanical condition from vibrations during the transformer’s transient processes, such as short-circuit and power-off conditions. Such processes generate a short transient vibration response, which yields a spectrum with poor frequency resolution. Vibration before the transient process could be ...
