Solution of large eigenproblems on a microcomputer
Advances in Engineering Software (1978), 1985Abstract A microcomputer program is presented for determining the lowest eigenfrequencies of large structural systems by using the finite element method. The solution procedure is based upon the subspace iteration technique. Householder's tridiagonalisation and the QL method are used in order to solve the eigenproblem in the reduced space at each ...

For more than a century, we have accepted the premise that once electricity is produced, it cannot be stored. This lack of storage causes extreme electricity price volatility (compared with other commodities) and hourly fluctuations in wholesale market prices, and has prompted specialized real-time markets that provide price fluctuations in 5- or 10 ...

Parallel Solution of Large Lyapunov Equations
SIAM Journal on Matrix Analysis and Applications, 1992The solution of large-order (\(100\leq n\leq 1000\)) Lyapunov equations \(AX+XA^ T+Q=0\) is considered. A parallel version of the Hammarling algorithm [cf. \textit{S. J. Hammerling}, IMA J. Numer. Anal. 2, 303-323 (1982; Zbl 0492.65017)] for large and dense \(A\) and a novel iterative parallel algorithm, called full-rank perturbed iteration (FRPI), for

LARGE STRAIN SOLUTIONS OF RUBBER COMPONENTS
Computers & Structures, 1983Abstract A Mooney-Rivlin material model for plane strain and axisymmetric analyses of rubber has been implemented in the ADINA computer code. Using a consistent penalty method, derived from a regularized mixed formulation, the nonlinear incompressibility constraint is weakened by a properly chosen projection procedure.

Solution of Schrödinger’s equation for large systems
Physical Review B, 1989Iterative diagonalization of the Hamiltonian matrix is required to solve very large electronic-structure problems. Present algorithms are limited in their convergence rates at low wave numbers by stability problems associated with large changes in the Hartree potential, and at high wave numbers with large changes in the kinetic energy.
