Typhoon disasters undergo a complex evolutionary process influenced by temporal changes, and investigating this process constitutes the central focus of geographical research. As a key node within the typhoon disaster process, the state serves as the fou
But now the situation becomes more interesting still when we consider the effect of polar and nonpolar solvents on the energies of the two states with their very different dipole moments. In a molecule like p-amino benzophenone, the π-π* state has much charge-transfer character and is more...
A long-standing crucial question with atomic nuclei is whether or notαclustering occurs there. Anαparticle (helium-4 nucleus) comprises two protons and two neutrons, and may be the building block of some nuclei. This is a very beautiful and fascinating idea, and is indeed plausible because ...
Following an elementary two-level model, the energy of the states resulting from this interaction is given by (6.1)E±=12(EN+ECB±(EN−ECB)2+4VCB.N2) where ECB(k) and EN are the energy of the GaAs conduction band and the nitrogen resonant state, respectively. VCB,N is a parameter...
The invention likewise relates to a method for regulating or controlling a state variable of the fuel cell system. The regulation or control is based on the estimated or temporally developed state vector of the fuel cell system. Likewise provided by the invention is a fuel cell system designed ...
However, strains’ directionality makes it challenging to form the stressing state mode (the vector or matrix of strains) and the parameter characterizing the mode. Therefore, a standard method is to model the strain as the scalar quantity: 𝑒𝑖𝑗=∫𝐹𝑗0𝜀𝑖d𝐹 or 𝑒𝑖𝑗 ...
and then the data are used to generate a model. There are two common types of filtering algorithms [16,18,19,20,21,22,23] and machine learning, which is mainly divided into traditional machine learning and deep learning. Fuzzy logic [24,25], support vector machines [26], and neural net...
a uniformly universal sequence of codes for countable memoryless sources, in which the n th code has a ratio of average codeword length to source rate bounded by a function of n for all sources with positive rate; the bound is less than two for n = 0 and approaches one as n increases...
Three such waves exist (for an elastically isotropic solid, there are two transverse waves and one longitudinal wave). For all three waves, the frequency u is a first-order homogeneous function of the components of the vector k; the function vanishes when k = 0. In other words, for ...
Many people only know “VR” through Google Cardboard because of the low price, and they deservedly think it’s just a gimmick, novelty or curiosity. They never get to feel the physicality, And that’s not the whole story. There are still two more important points to consider. The first...
