Random Excitation of a Loaded Nonlinear String

Journal of Applied Mechanics, 1960
This paper is devoted to the study of a chain of particles connected by a massless elastic string subjected to random excitation. It is shown that, as a result of the additional stress induced by the stretching of the string, the mean squared deflection of every particle is reduced compared with that for the equivalent linear problem.

Scheduling divisible loads with nonlinear communication time

IEEE Transactions on Aerospace and Electronic Systems, 2015
A scheduling model for single level tree networks with various distribution policies is studied in which the communication time from the root to each node is nonlinear in the size of the load. An iterative method is implemented to solve the optimal load distribution.

Microwave cavity with nonlinear load

MMET Conference Proceedings. 1998 International Conference on Mathematical Methods in Electromagnetic Theory. MMET 98 (Cat. No.98EX114), 2002
A rigorous solution and numerical results for the problem of excitation of a resonator with nonlinear load are presented. Numerical results are obtained for the excitation by a primary source, whose first or third harmonic in frequency is close to resonance at the fundamental mode H/sub 101/.

Modeling nonlinear scattering processes on antennas with a nonlinear load

Antennas
To determine the amplitude, spatial and frequency properties of nonlinear scattering on antennas with a nonlinear load, it has been proposed to measure or calculate three dependencies: the amplitude characteristic (the dependence of the intensity of the electromagnetic wave scattered on harmonics on the intensity of the irradiating wave of the probing ...

Nonlinear fuzzy logic control of a PWM inverter with a nonlinear load

PowerCon 2000. 2000 International Conference on Power System Technology. Proceedings (Cat. No.00EX409), 2002
Capacitor input filter loads (nonlinear) typically cause voltage distortion in DC to AC inverter waveshape. Nonlinear fuzzy logic control fields promise in reducing this compared with conventional PID control. Comparisons between nonlinear fuzzy logic proportional derivative controllers and conventional linear PID controllers are made by simulating a ...

Nonlinear control for AC/DC power system with nonlinear loads

2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005
In view of the nonlinearity of loads and HVDC in power systems, the M derivative, M bracket and MIMO feedback linearization based on nonlinear differential algebraic system (NDAS) are introduced into the design of nonlinear controller for parallel AC/DC power system.

Nonlinear load exceedance model for cyclic load processes: development

Structural Safety, 1999
Studies of structural response due to stochastic load processes have been extended to include nonlinear material response. The studies on the Poisson processes with rectangular pulses were for positive pulse intensity such as gravity load. The reliability analysis developed was not applicable for processes with reversible cyclic load pulses such as ...

Traveling Loads on Viscoelastic Plates on Nonlinear Foundations

Journal of Applied Mechanics, 1977
Within the framework of Kirchhoff-type prestressed plate theory, the steady-state response of a viscoelastic plate strip on a nonlinear dissipative foundation to the action of general traveling loads is considered. Since an hereditary integral-type viscoelastic constitutive model is employed, the governing field equation is of the nonlinear ...
