Estimation of transition matrix of finite Markov process, abelian groups, structure of near rings and near rings homomorphisms, and metrization of topological spaces
Generation and interpretation of input and output data for Structural Analysis and Matrix Interpretive System /SAMIS/
Solid state matrix for detecting low energy electrons
Residual stress effect on stress-strain curve of uniaxial composite consisting of stainless steel wire and aluminum alloy matrix
Hamiltonian for free particle of arbitrary spin and mass formulated in terms of spin matrix polynomials, noting independence of expansion coefficients
Nilsson model used to derive expressions for nuclear matrix elements, considering forbidden beta decay of spheroidal-shaped nuclei
Computer program generates the stiffness matrix for a particular type of structure from geometrical data, and performs static and normal mode analyses. It requires the structure to be modeled as a stable framework of uniform, weightless members, and joints at which loads are applied and weights are lumped.
XY relay switching matrix provides complete random access and random release of 400 points. A mercury-wetted bistable relay with independent set and reset coils is the unique feature associated with each point.
