Theory of the Relativistic Oscillator
American Journal of Physics, 1957This is a study of the motions of a particle subject to the restoring force exerted by a linear spring, under the assumption that the mass depends upon the speed according to the formula given by the theory of special relativity.

The Sturmian Theory of Oscillations
The Mathematical Gazette, 1954The Sturmian theory is concerned with the number of zeros that a solution of a linear differential equation of the second order may have in a given interval of the independent variable. As usually presented ( e.g.

Canonical quantization of QED in finite systems is performed in terms of new b-photon, f-electron, and f c -positron, which are called alpha-oscillators. The alpha-oscillator algebra is useful for non-perturbationally space-time resolved simulation solving the dual Cauchy problems of the time-dependent QED Hamiltonian \( {\widehat{H}}_{\mathrm{QED}}(t)

Journal of Applied Physics, 1967
The efficiency, negative resistance, and conditions for space-charge control relevant to operation of a bulk semiconductor diode in the limited space-charge accumulation (LSA) mode of oscillation are discussed. Numerical results for n-GaAs indicate a maximum dc to rf-conversion efficiency of 18.5% for sine-wave excitation. The usable range of doping to

Free-oscillation coupling theory
1988The free oscillations of an elastic, spherical earth model can be combined using variational or Galerkin techniques to form hybrid oscillations that represent the free oscillations of a rotating, anelastic and laterally-variable earth model. With supercomputers and/or array processors, it is feasible to synthesize realistic long-period seismograms from
