From Interval Computations to Constraint-Related Set Computations: Towards Faster Estimation of Statent errors. In this case, based on the measurement result ., we can only conclude that the actual (unknown) value . of the desired quantity is in the interval .. In interval computations, at each intermediate stage of the computation, we have intervals of possible values of the corresponding quantit

Dynamic Steady-State Analysis of Structures under Uncertain Harmonic Loads via Semidefinite Programected to uncertain driving loads. The amplitude of harmonic driving loads is supposed to obey a non-probabilistic uncertainty model. We formulate a semidefinite programming problem, whose optimal value corresponds to a confidential bound for the characteristic amount of dynamic steady-state response

Universal eigenvalue statistics and vibration response prediction matrix is sufficiently random, regardless of the statistics of the matrix entries. This distribution is the same as that associated with a class of random matrix known as the Gaussian Orthogonal Ensemble (GOE). The underlying reason for this behaviour is explored here, and it is concluded that the

Statistical Energy Analysis and the second principle of thermodynamicsof thermodynamics. In this study, the definition of vibrational entropy is introduced for sub-systems containing energy and modes. The rate of entropy production at interfaces between sub-systems is also derived. Finally, in steady-state condition, an entropy equilibrium is reached. The meaning of e

Modeling noise and vibration transmission in complex systemst, the justification for statistical analysis methods arises not because of a need to “model uncertainty” but rather because of a need to “reduce model complexity”. This distinction is important; analysis methods which increase model complexity (by requiring large amounts of input information) are s

A Power Absorbing Matrix for the Hybrid FEA-SEA Method005) is the power absorbing dynamic stiffness matrix. The derivation of such a matrix associated with the flexural motion of a thin, flat, homogeneous plate, based on the cylindrical wave representation of the displacement field over a single convex domain (Lande 2005), is presented here.
