This article presents quality assessment results for the software generators of pseudo-random sequences (PRS) presented in [1; 2] for QS simulation, including second-order hyper-Erlang and hyper-exponential distributions of the second order, that flows organically from these works. These distribution laws are in demand in queuing theory as it provides a big range of changes in the variation coefficient which plays an important role in the average queue delay calculating. There is no data on such generators neither in scientific literature, no in the GPSS WORLD library. Software generator quality evaluation, regardless of the programming language, is usually made according to statistical tests. In this case, chi-squared and Kolmogorov-Smirnov’s tests are used. In addition, the comparison between theoretical and statistical aspects of the corresponding order is provided. Unlike simple distribution laws, for which the use of the above mentioned statistical tests is provided for in well-known software products and does not cause any difficulties, in our case automatic testing is impossible. The well-known packages STATISTICA, STATGAPHICS, Matlab/Simulink, etc. do not provide for the use of the hyper-Erlang and hyper-exponential distribution laws we consider. Therefore, the Pearson statistical test is calculated and checked manually. The presented results should be useful for professionals of discrete event modeling in the GPSS WORLD environment.
本文介绍了[1；2]中提出的用于 QS 模拟的伪随机序列（PRS）软件生成器的质量评估结果，包括二阶超二郎分布和二阶超指数分布，它们是这些著作的有机组成部分。队列理论需要这些分布规律，因为它提供了变化系数的大范围变化，而变化系数在计算平均队列延迟时起着重要作用。科学文献和全球定位系统 WORLD 库中都没有关于此类生成器的数据。无论使用哪种编程语言，软件生成器的质量评估通常都是通过统计检验进行的。在这种情况下，使用的是卡方检验和 Kolmogorov-Smirnov 检验。此外，还提供了相应顺序的理论和统计方面的比较。与简单分布规律不同的是，上述统计检验的使用在知名软件产品中都有提供，不会造成任 何困难，但在我们的案例中，自动检测是不可能的。知名软件包 STATISTICA、STATGAPHICS、Matlab/Simulink 等都不提供使用我们所考虑的超 Erlang 和超指数分布规律的功能。因此，需要手动计算和检查皮尔逊统计检验。所提供的结果对于在 GPSS WORLD 环境中进行离散事件建模的专业人员应该是有用的。

The widespread use of unmanned aerial vehicles for various purposes, expanding scope of their application and ever-increasing requirements for the durability of communication channels urgently require the development of new effective antenna solutions for the equipment of command radio control lines and payloads. The article is devoted to a brief analysis of the available information about the radio lines of unmanned aerial vehicles, solutions in the field of antennas for the equipment of command control radio lines and payload and the study of perspective antennas for the repeaters placed on unmanned aerial vehicles. The review of the general types of antennas that may be installed on unmanned aerial vehicles, including pin, microstrip and spiral ones, as well as antenna arrays based on them, made it possible to substantiate the prospects of using low-profile and spiral antennas for repeaters installed on unmanned aerial vehicles. The studies conducted on the frequency and spatial characteristics of low-profile and spiral antennas have confirmed their sufficient effectiveness. Proposed solutions can be used as a basis for development of perspective antennas for repeaters installed on unmanned aerial vehicles.

Resistive elements possess independence of their resistance from frequency in a very wide band of frequencies. Therefore, developing algorithms of parametrical synthesis of amplitude-phase modulators with the use of resistive matching four-pole networks is an actual task. In this work, matching provides the set dependence of a relation of modules and a difference of transfer function phases from frequency in two conditions of a nonlinear element defined by two levels of a control signal. The nonlinear part represents a three-pole nonlinear element with a feedback. The interrelations between elements of the classical matrix of transferring in four-pole networks are established, and the formulas for defining resistances of their two-pole units that are optimum by the criterion of amplitude-phase modulation of an outputt signal are determined. The theory of four-pole networks, as well as the methods of matrix algebra, parametrical synthesis of UHF control devices, decomposition and circuit analysis of radio devices are used. The comparative analysis of theoretical results (AFC and PFC of modulators in two states) received by mathematical modelling in the «MathCad» system and of experimental results received by circuit simulation in the «OrCad» and «MicroCap» systems shows their satisfactory coincidence.

In the classical theory of queuing systems, the assumption of mutual independence of events is fundamental, so we propose to consider the basic principles of the interval method of traffic analysis, which allows us to replace analysis of time intervals between neighboring requests and time intervals for processing requests by analyzing one random variable, i. e. the number of requests received during successive intervals of time for processing each of requests. The concepts of mean maximum values of queues and limiting maximum values are introduced. It is shown that the limit maximum value in a queue will be the largest of the possible maximum values for a given total value of requests in queues during one service cycle. The mean maximum score is the average of the maximum queue values. To determine the characteristics of traffic, we use the well-known «Leaky_bucket» algorithm. The proposed traffic model is based on the total number of requests during their processing cycles. Experimental modeling of the proposed method showed that variance and correlation properties of a specified random variable for a given load completely characterize the average queue size in a queuing system.

The OpenFlow protocol is the main technology formed among the first concepts of software-defined systems. This technology makes it possible to develop external software shells necessary for increasing the functionality of switching, routing and information processing processes, not depending on modern equipment and firmware versions and formed separately by an external controller. One of the main tasks of the work that needs to be done is to study changes in packet delays on the FloodLight controller, which does not have a flow table of the OpenFlow switch. In addition, it is necessary to find out the packet loss in the experimental network sample in the Mininet virtual environment. The study was conducted using some modern tools and technologies, and an analysis of the domain and requirements was previously carried out. Based on the results obtained experimentally, some conclusions were drawn and some recommendations on the use of the OpenFlow protocol in early stages of development for small networks were made.
