Eigenvalue analysis eigenvector

The fast stage of relaxation of a complex reaction network could be described as mass transfer from nodes to correspondent attractors of auxiliary dynamical system and mass distribution in the attractors. After that, a slower process of mass redistribution between attractors should play a more important role. To study the next stage of relaxation, we should glue cycles of the first auxiliary system (each cycle transforms into a point), define constants of the first derivative network on this new set of nodes, construct for this new network an (first) auxiliary discrete dynamical system, etc. The process terminates when we get a discrete dynamical system with one attractor. Then the inverse process of cycle restoration and cutting starts. As a result, we create an explicit description of the relaxation process in the reaction network, find estimates of eigenvalues and eigenvectors for the kinetic equation, and provide full analysis of steady states for systems with well-separated constants. [Pg.110]

The analysis of molecular spectra requires the choice of an effective Hamiltonian, an appropriate basis set, and calculation of the eigenvalues and eigenvectors. The effective Hamiltonian will contain molecular parameters whose values are to be determined from the spectral analysis. The theory underlying these parameters requires detailed consideration of the ftmdamental electronic Hamiltonian, and the effects of applied magnetic or electrostatic fields. The additional complications arising from the presence of nuclear spins are often extremely important in high-resolution spectra, and we shall describe the theory underlying nuclear spin hyperfine interactions in chapter 4. The construction of effective Hamiltonians will then be described in chapter 7. [Pg.73]

Experiments on transition for 2D attached boundary layer have revealed that the onset process is dominated by TS wave creation and its evolution, when the free stream turbulence level is low. Generally speaking, the estimated quantities like frequency of most dominant disturbances, eigenvalues and eigenvectors matched quite well with experiments. It is also noted from experiments that the later stages of transition process is dominated by nonlinear events. However, this phase spans a very small streamwise stretch and therefore one can observe that the linear stability analysis more or less determines the extent of transitional flow. This is the reason for the success of all linear stability based transition prediction methods. However, it must be emphasized that nonlinear, nonparallel and multi-modal interaction processes are equally important in some cases. [Pg.59]

In the example which follows it is calculated separately from the usual rate sensitivities and is a simple one-dimensional array. Another approach would be to treat temperature as though it were a concentration, and to include it in the eigenvector/eigenvalue analysis. [Pg.331]

The algebraic problem (10a) can be numerically solved to provide results for the eigenvalues and eigenvectors vji from this matrix eigenvalue problem analysis [31], which will be combined within the inverse formula (9a) to provide the desired eigenfunctions of the original eigenvalue problem. [Pg.44]

The application of the Routh-Hurwitz analysis or the direct calculation of the eigenvalues and eigenvectors of the Jacobian Jg of the network of reactors is a formidable task for moderate and large arrays of coupled reactors. There is an alternative approach, a spectral analysis of networks, that works for any size array of coupled reactors, as long as the array is homogeneous, i.e., / -, = /i for all i,i = 1,..., n, and the coupling is diffusive. In this case, the system (13.4) has a uniform steady state ... [Pg.368]

A well-known technique for dynamic analysis of structures is the Modal Analysis. It consists of obtaining the natural frequencies and their associated modeshapes. Mathematically, modal analysis is performed by obtaining the eigenvalues and eigenvectors of the homogeneous equation ... [Pg.1170]
