In this paper a brief overview of methods to assess the reliability of mechanical systems and structures is given. A selection of computational procedures, stochastic structural dynamics, stochastic fatigue crack growth, and reliability based optimization are discussed. It is shown that reliability based methods may form the basis for a rational decision making.

1. Review the background and rational use of interventional pain techniques. 2. Assess adequate patient selection, indications, and the evidence to support the use of surgical interventional therapies for neuropathic pain. 3. Identify pros and cons of diff erent surgical ablative and functional neurosurgical interventional therapies to help determine the proper choice of technique for the treat...

We investigate the parametrization issue for real discrete-time stable all-pass multivariable systems by means of a real tangential Schur algorithm. A recursive construction of balanced realizations is associated with it, that possesses a very good numerical behavior. A chart selection strategy is given which makes use of the real Schur form of the dynamic matrix. Application to rational L-appr...

The article tells about the problem of railway infrastructure objects reliable, safe, and effective operation on an example overhead contact line mode rational selection. modelling results are described. model is considering exploitation climatic conditions based clusterization, classification, neuronal network methods for predictive analysis a large amount data.

The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$. Some general properties of rational character tables are also considered into account.The aim of this paper is to compute the rational character tables of the dicyclic group $T_{4n}$, the groups of order $pq$ and $pqr$.

Abstract We introduce a new method for Estimation of Signal Parameters based on Iterative Rational Approximation (ESPIRA) sparse exponential sums. Our algorithm uses the AAA rational approximation discrete Fourier transform given equidistant signal values. show that ESPIRA can be interpreted as matrix pencil (MPM) applied to Loewner matrices. These matrices are closely connected with Hankel usu...

Autonomous agents, by definition, have the freedom to make their own decisions. Rational agents execute actions that are in their “best interests” according to their desires. Action selection is complicated due to uncertainty when operating in a dynamic environment or where other agents can also influence the environment. This paper presents an action selection framework and algorithms that are...

A method is proposed to construct spiral curves by inversion of a spiral arc of parabola. The resulting curve is rational of 4-th order. Proper selection of the parabolic arc and parameters of inversion allows to match a wide range of boundary conditions, namely, tangents and curvatures at the endpoints, including those, assuming inflection.

In order to appropriately manage patients with lung cancer, it is necessary to properly stage the tumor. The ACR Appropriateness Criteria is designed to provide an overview of the value of different imaging techniques in the non-invasive staging of lung cancer and allow for the rational selection of imaging studies to arrive at the appropriate clinical stage.
