Charles Seeger’s ‘Versions and Variants of the Tunes of “Barbara Allen”’ (1966) is a sophisticated discussion and analysis of two of the tune families associated with this ballad. (In Bronson, ii, four tune families for ‘Barbara Allen’ are represented by over 200 individual tunes.) ...
However, there is no reason to suppose that, at this time, these tuning patterns stood in any straightforward and organised relations to one another. It was only around the year 400 that attempts were made by a group of theorists known as the harmonicists to bring these harmoniai into a ...
In contrast, the information on the vibrational coupling of the H-O-H bending mode of water is lacking, even though the bending mode is an essential intermediate for the energy relaxation pathway from the stretch mode to the heat bath. By combining static and femtosecond infrared, Raman, and...

The following example creates a list box that allows the user to change the user interface mode for an embedded Windows Media Player object. The AxWMPLib.AxWindowsMediaPlayer object is represented by the variable named player. CSharp複製
For free vibration analysis, the solution of eqn (18), is represented by a linear combination of all modes: [23]x(t)=∑l=1nxl(t)=∑l=1n(Alsinωlt+Blcosωlt)ul where Al and Bl are determined by the initial conditions. The concept of modes of vibration is extremely important in ...
The RMSD corresponding to the displacement described by the arrows is displayed. User can change the RMSD value to rescale the arrows. The scaling factor that produces the specified RMSD is printed to the VMD console (along with the magnitude of the mode provided in NMD file). ...
−iγ0I is the background loss term in which I is a two-dimensional identical matrix, 2γ = γA − γB indicates the gain/loss contrast within one dimer (the decay rates of sites A and B in each dimer are represented by γA and γB, respectively), and σ x,y,z ...
It can be shown that by the end of the 11th century the ‘Guidonian hexachord’ must have been conceived as fully transferable to any place in the system where its stepwise successions would fit, that is, where there were affinities (see Commentarius anonymus, ed. Smits van Waesberghe, ...
Ξ, is given by(6)UΛUT=Ξ:=DDT/m,where U=[u1, u2, …, uN] represents an N×N unitary matrix, Λ is the diagonal matrix of eigenvalues, m = m1 + m2 + … + ms. If the number of principal components is n, the loading matrix P: = Pn is represented as the matrix ...
