Measurements using the Transmission/Reflection line method involves placing a sample in a section of coaxial line and measuring the two ports complex scattering parameters with a vector network analyzer. For calculation of both the permittivity and permeability Nicholson-Ross-Weir method is used. Computation uncertainties problems on a complex plane are considered. An algorithm of SCPI protocol application for remote control of vector network analyzer Rohde&Schwarz series ZVA using LabVIEW programming environment is provided.

This article is proposing a new parametric bootstrap method of evaluation of control limits of charts for asymmetrically distributed process measurements. The proposed method modifies the authors' approach to evaluation of control limits based on pseudorandom numbers generation (presented in [1]) by using the unbiased estimator of within-subgroup variation (pooled variance) at the step of evaluation of the distribution parameters hence decreasing the probability of false alarm in a process monitoring phase (Phase II). The use of an average statistic of within-subgroup variation increases the robustness of control limits (to the presence of exceptional variation) that allows applying the proposed method in a retrospective analysis (Phase I). The method does not require nonlinear transformations of data, which may complicate the technical interpretation and application of the results of analysis. The proposed parametric bootstrap method may be used to construct a control chart for any statistic when process measurements are distributed in accordance with any (one- or two-parameter) theoretical law. Quality variables with such distributions are found in many industries: telecommunications, electronics, mechanical engineering, etc. A comparison between the performance of charts for averages and standard deviations of the proposed method and the same charts of alternative methods1 in Phase II is made in terms of type-I and type-II error rates (using Monte Carlo simulations for process measurements distributed in accordance with the lognormal and the Weibull laws). The type-I error rates of charts for averages and standard deviations of the proposed method are closer to the required value than the type-I error rates of charts for averages and standard deviations of the alternative methods. The type-II error rates of these charts of the proposed method enable them to detect large shifts in the process location and variance very quickly.

The report encompasses a number of problems concerning the use of integrated inertial technologies for dynamic diagnostics of railway track. Development of high-speed railroad transport in Russia imposes strict requirements to the railway flaw detection systems. Most of all those requirements apply to the measurement of dynamic interaction between the rail car and the railway. Our research allowed us to produce requirements to the inertial measurement sensors and systems installed on various parts of the rail car: bogie's frame and axle boxes. The Railway Track Diagnostics System (RTDS) was used as the core of the integrated navigation and positioning system. The RTDS system was designed in our department of Laser measurement and navigation systems and was successfully implemented on Russian Railways. One of its parts is a set of MEMS sensors which was initially meant to detect short-distance (pulse) geometric railway flaws. After the system was brought to a real car, operational testing showed that these sensors can be used as rail joint detectors, effectively turning them into high-precision ATON markers. Combined with the (already developed) mathematical model of odometer error, this allows to achieve needed accuracy in railway navigation.

Implementation issues of direct adaptive control system of nonlinear nonstationary objects with uncertain descriptions are considered. Simultaneously the control object is not fully measured. It is proved that the exponential dissipation, i.e. the final adaptation process boundedness, can be ensured. Estimates of accuracy and speed of convergence between adaptee and reference model trajectories are given in detail.

This Development of Fault Tolerant Control (FTC) systems presumes the development of a certain control method and testing it, which is not always possible in the real life and in the frames of a real technical system. Thus, it is great importance for a researcher or an engineer to have the possibility to check the proposed control method through simulation of different faults and the system's reaction on them using a set of benchmark models. These models should be complex and representative enough and allow simulation of different types of faults as well as varying the faults number and the time of occurrence. The goal of the work carried out was the creation of a convenient environment for the development of FTC systems for technical objects and complexes based on a set of benchmark representative research models for experimental testing of different approaches to diagnostics and assurance of fault-tolerant control.

This paper briefly mentions the micro controller unit, and then goes into details about the exact regulations for SRM. Firstly, it proposes the main driving state control for motor and the importance of the motor position sensor. For different speed, the controller will choice various styles such as voltage chopper control, angle position control and current chopper control for which owns its advantages and disadvantages. Combining the strengths of the three discrepant methods, the main control chip will intelligently select the best performing control depending on the load and speed demand. Then the exact flow diagram is showed in paper. At last, an experimental platform is established to verify the correctness of the proposed theory.
