The authors develop a system of differential equations describing the motion of the structural system equipped with DFP bearings. The Runge-Kutta numerical method, specifically the ode15s function in MATLAB, was used to solve these equations. The results of the calculations provide a comparison of the damping efficiency of the structural system with and without the use of DFP bearings, assessing the effectiveness of vibration isolation during an earthquake, with three components X, Y, and vertical considered.

In this laboratory experiment, you will use SPICE to study sinusoidal waves on lossless transmission lines. Our goal is for you to become familiar with the basic behavior of waves reflecting from loads in transmission lines, and compare the simulations with numeric calculations and the Smith Chart.

Deterministic uncertainty propagation methods are certainly powerful and time-sparing but their access to uncertainties related to the power map remains difficult due to a lack of numerical convergence. On the contrary, stochastic methods do not face such an issue and they enable a more rigorous access to uncertainty related to the PFNS.

Mixed mode I/II stress intensity factors of an edge slant-cracked plate under tensile loading were assessed. A two-dimensional finite element analysis was employed using ABAQUS. Various crack lengths and angles were analyzed. The effect of the crack location at the plate edge was also examined. Crack initiation angles were calculated.

A large number of proteins, found experimentally to have different optimum pH of maximal stability, were studied to reveal the basic principles of their preferenence for a par-ticular pH. The pH-dependent free energy of folding was modeled numerically as a function of pH as well as the net charge of the protein. The optimum pH was determined in the numerical calculations as the pH of the minimum free energy of folding. The experimental data for the pH of maximal stability (experimental optimum pH) was repro-ducible (rmsd¼0.73)....

LYAPUNOV FUNCTIONALS CONSTRUCTION FOR STOCHASTIC DIFFERENCE SECOND-KIND VOLTERRA EQUATIONS WITH CONTINUOUS TIME LEONID SHAIKHET Received 4 August 2003 The general method of Lyapunov functionals construction which was developed during the last decade for stability investigation of stochastic differential equations with aftereffect and stochastic difference equations is considered. It is shown that after some modification of the basic Lyapunov-type theorem, this method can be successfully used also for stochastic difference Volterra equations with continuous time usable in mathematical models.
