Today, this fault location analysis is completed within the digital signal processing method. Scenario packet transmission source of some of the attacks and intruders get data packets, and route alters identity problem before cumulative. Reduces processing time can find significant speed advantage and the accuracy of the classical method of calculation failure and presents a simple analog implementation. Back-propagation time is modeled as a fault location estimation of each repeated signature and the switches along with the network. Rapid Packet Transmission Algorithm (RPTA) by a certain load distribution, which leads to restrictions to avoid packet loss. Due to increased packet transmission, improving technology to limit non-destructive testing costs is in great demand. Our algorithm means that each candidate seriously and error detection mechanisms and can provide any fault tolerance of the routing path assessment. Simulation results with different fault resistance indicate that these methods are robust, fault-type, and the initial angle of the disorder. To find the faulty segment, use the transient to the common connection point. Good accuracy for complex network topologies also reduces the overhead generation region by implication checking logic; thus, compared to the typical failure locations of the techniques developed to reduce the total number of required effects, this solution charm.

There are several kinds of probability distribution widely used in quantitative texture analysis. One of them is the normal (Gaussian) distribution. The main application of the normal distribution is the orientation distribution function and pole-figure approximation on the rotation group SO(3) and sphere S2accordingly. The calculation of the normal distribution is a complicated computational task. There are currently several methods for calculating the normal distribution. Each of these methods has its advantages and disadvantages. The classical method of calculation by Fourier series summation is effective enough only in the case of continuous texture approximation. In the case of sharp texture approximation, the analytical approach is more suitable and effective. These two calculation methods result in a continuous function. The other method allows a discrete orientation set to be obtained, corresponding to a random sample of normal distribution similar to experimental electron backscatter diffraction data. This algorithm represents a statistical simulation by the particularized Monte Carlo method. A short review of these computational approaches to the calculation of normal distributions on the rotation group is presented.

Abstract Capability measurement of manufacturing processes creates basic attributes for the production of conformity products, those that meet the necessary conditions in terms of tolerance limits for all important parameters. They are also important in the supplier-customer relationships context as one of the important easily predictable but highly effective indicators of the quality production of delivered products. In many manufacturing companies, the capability measurement is performed by using capability indicators, where the method of calculation is based on the assumption of normality of the distribution of the measured product parameter, as well as the assumption of constant median value but also variability during the monitored period. However, in practice we often are able to see such parameters of manufacturing products or processes, which do not meet the expectations required in the classical method of capability indexes calculation. The problems are usually in a different than normal models of the distribution of a random variable representing a specific parameter of a product or process, as well as in the excessive variability of median values during the time in these so-called non-standard parameters. There will be presented on the particular manufacturing product, how certain non-conformities occur during the capability indexes measurement indices in the classical way for selected non-standard parameters. The paper describes how it is possible to modify the common method of calculating the mentioned capability indexes in a simple way so that they are applicable in specific production conditions.

We suggest method of calculation of one-dimensional temperature field in multilayer nanostructures. Our method allows obtaining non-stationary temperature distribution in the periodical and non-periodical spatial structures with a different degree of periodicity. Comparison temperature distributions in the multilayer nanostructures and equivalent continuous samples are performed in this study. In addition we suggest experimental application of our method for estimation an average value of thermal Kapitza resistance.

The possibility of creating a method of calculation is not stationary temperature field induced in the material during cutting. A new methodological approach does not determine the steady-state temperature field in a homogeneous material.
