Two-Photon Quantum Interference Polarization Spectroscopy: Measurements of Transition Matrix Elements in Atomic Rubidium
<p>The estimation of the adequacy of theoretical calculations on the atomic structure requires availability of the precise experimental data on radiative properties of the atoms. Such data is also required in astronomy and some important areas of technology. The lack of precision of traditional …

A Markovian manpower planning, human resource valuation model
… actual firm. These data were used to develop a transition matrix for the firm. The transient states of the matrix correspond to the employment positions within the firm, i.e., staff, manager, and partner. The absorbing states of the matrix were for employees leaving the firm (1) before becoming …

Eigenvalue Spacings of Transition Matrices Associated to Directed Graphs
… theorem in terms of the eigenvalues of the transition matrix. This expression reveals that the convergence behaviour is governed not only by the spectral gap but also by the spacings between eigenvalues. Interpreting the transition matrix as describing a random walk on a directed graph, we …

Monotone bounds on the productivity of fixed-cycle production lines
… bounds on the productivity of longer lines. The transition matrix associated with an N-machine line is shown to be stochastically monotone yielding monotone increasing lower bounds and monotone decreasing upper bounds which converge to the productivity of the line. These results are then extended …

Meson Photo-Couplings From Lattice Quantum Chromodynamics
… contain information about many radiative transition matrix elements simultaneously. We develop and implement the technology necessary to isolate a single matrix element via the use of optimized operators, operators designed to interpolate a single meson eigenstate, which are constructed as …

Stability and robustness analysis tools for marine robot localization and mapping applications
… requiring boundedness and convergence of the transition matrix Euclidean norm. These theorems yield a stability test for the feedback controller. Perturbations are then considered using a theorem on the convergence on the perturbed system transition matrix, yielding a robustness test for the …

Measurements of Gamow-Teller strength in medium mass nuclei using (p,n) reactions at intermediate energies
… Beta decay studies enable the extraction of the transition matrix elements to high precision. However, most GT transition rates deduced from beta decay measurements turn out to be smaller than the calculated single particle rates [1, 2, 3], a phenomenon that has become known as the quenching of …

Identification of linear sampled data systems.
… least squares estimator is derived for the state transition matrix phi of a linear, stationary sampled data system operating in a stochastic environment. The estimator is shown to be unbiased and minimum variance under the condition of full observability of the state vector of the system. The …

Limiting Conditional Distributions: Imprecision and Relation to the Hazard Rate
… it may be unrealistic to assume that the transition matrix of a Markov chain can be determined exactly. It may be more plausible to determine upper and lower bounds upon each element, or even determine closed sets of probability distributions to which the rows of the matrix may belong. …

Modeling Transition Probabilities for Loan States Using a Bayesian Hierarchical Model
… the borrower fails to make monthly payments. The transition matrix contains in each location a probability that a borrower in a given state one month moves to the possible delinquency states the next month. In order to use this model, it is necessary to know the transition probabilities, which are …
