Fundamentals of the Probability Theory and the Theory of Random Processes,ss of manufacturing parts of the same type. We may establish, that the dimensions of the parts will vary about a certain predetermined value. Since these deviations are of random nature, the measurements of the finished parts do not allow us to predict the dimensions of the next part. For large batc

Stationary Random Functions (Processes),widespread. Their probability characteristics do not depend on the choice of time reference point, i.e. are invariant relative to the shift of time. Accordingly, a random function .(t) is defined as stationary, if the probability characteristics of a random function . (t + t’) at any t’ coincide wit

Fundamentals of the Markov Processes Theory,correlation function has been considered. Unfortunately, far from all encountered applied problems can be solved by correlation theory methods. A case in point is the problem of determining the probability that the ordinate of a random function will exceed a particular given value, which often arise

Random Vibrations of Systems with One Degree of Freedom, tackled in this field include analysis of object protection systems under the action of random disturbances, analysis of vibrations of airborne vehicle structures elements caused, for example, by the action of atmospheric turbulence, launch of airborne vehicles, the vehicles motion on roads with ra

Random Vibrations of Systems with Finite Number of Degrees of Freedom,.1 usually considered that with one degree of freedom is a system with two degrees of freedom (if we neglect the inertia of the rod and examine the motion of the mass only in the plane of the drawing), as the real lumped mass has a non-zero moment of inertia . about the central axis that is perpendi

Random Vibrations of Strings; Longitudinal and Torsional Vibrations of Straight Rods, elements (for example, rod elements in Fig. 5.8, 5.9, 5.24, 6.7, 6.10) are inertialess, which, of course, is not quite so. This is true only in cases, where concentrated masses are considerably greater than the masses of elastic elements. Unfortunately, the term considerably greater does not relate
