In this paper, from a cybernetic perspective, the human-nature interactions are considered in the context of modern climate change, unprecedented in its scale and rate caused by anthropogenic activity. The developed structure of the “climate-economy” cybernetic system is presented, the weaknesses of the global governance bodies are analysed, and the main causes of the uncertainties in assessing climate change and the economic damage caused by this change are discussed. It is noted that adaptation measures and strategies developed and implemented by governments of different countries and intergovernmental organizations do not eliminate the causes of global warming and, therefore, have limited capacities, since humans and nature can exist only under specified environmental conditions. Going beyond these conditions, due to climate change, can lead to a global biological catastrophe. Climate policy decisions are made under uncertainty due to the ambiguity of estimates of the future climate, which, in turn, is the result of an insufficiently adequate description of feedbacks in the climate system models. Using low-parametric models of the Earth's climate system, the influence of system’s feedbacks on tangible inter-model differences of climate change estimates obtained using modern climate models of a high degree of complexity is illustrated. Since the climate change adaptation measures proposed by experts are not the struggle with causes, but the fight with consequences, we see geoengineering as a radical adaptation strategy. In contrast to previous studies, we consider the problem of purposefully modifying climatic conditions, implemented by geoengineering methods, within the framework of optimal control theory with mathematical formalization of geoengineering objectives and methods for achieving them. In this paper, an example of the formulation and solution of the optimization problem for stabilizing the Earth’s climate through the injection of finely dispersed sulfate aerosol into the stratosphere is presented.
本文从控制论的角度考虑了人类活动引起的规模和速度空前的现代气候变化背景下的人与自然相互作用。提出了“气候-经济”控制论系统的发达结构,分析了全球治理机构的弱点,并讨论了评估气候变化不确定性的主要原因以及这种变化造成的经济损失。需要指出的是,各国政府和政府间组织制定和实施的适应措施和战略并不能消除全球变暖的原因,因此能力有限,因为人类和自然只能在特定的环境条件下生存。超出这些条件,由于气候变化,可能导致全球生物灾难。由于对未来气候估计的模糊性,气候政策决策是在不确定的情况下做出的,而这种不确定性又是气候系统模式中对反馈描述不充分的结果。利用地球气候系统的低参数模式,说明了系统反馈对使用高度复杂的现代气候模式获得的气候变化估计的有形模式间差异的影响。既然专家们提出的气候变化适应措施不是与原因作斗争,而是与后果作斗争,我们将地球工程视为一种激进的适应策略。与以往的研究不同,我们在最优控制理论的框架内考虑了通过地球工程方法有目的地改变气候条件的问题,并将地球工程目标和实现它们的方法进行了数学形式化。本文给出了通过向平流层注入细分散的硫酸盐气溶胶来稳定地球气候的优化问题的公式和求解实例。

The problem of a priory control of potential degeneration of continuous multichannel dynamic systems is considered in the paper. Degeneracy is a property of a system describing operability of a multichannel dynamic system together with the basic properties of stability, reliability and invariance to the changing conditions. An assessment of potential generation of a system and its configuration together with the interconnections and polynomial exogenous signal is proposed. Degeneration process of a multichannel dynamic systems is a process of the rank reducing of the linear operator of the system. This statement is a basic concept of the degeneration factors approach. Algebraic properties of the matrix of the system’s operator is considered, and the matrix is named as the criterion matrix. Degeneration factor is calculated with the singular values of the criterion matrix. The global degeneration factor is conditional number of the criterion matrix of a system. In contrast to previous solutions it is proposed to form the criterion matrix of a system with the resolvent of its state matrix. Deparameterization of the linear algebraic problem is realized by additive decomposition of the output vector of the system by derivatives of the exogenous signal, and the steady-state mode of the system is considered. The procedure of a priori estimation of degeneration of continuous multichannel dynamic systems is proposed. The ways to achieve the required value of degeneration of the criterion matrix of the system with the modal control methods are discussed. The paper is supported with examples.
研究了连续多通道动态系统潜在退化的优先控制问题。简并性是描述多通道动态系统的可操作性以及稳定性、可靠性和对变化条件的不变性的基本性质。提出了一种评估系统电位产生及其配置的方法,并考虑了系统间的相互关系和多项式外生信号。多通道动态系统的退化过程是系统线性算子降阶的过程。这种说法是退化因素方法的基本概念。考虑了系统算子矩阵的代数性质,将该矩阵称为判据矩阵。利用准则矩阵的奇异值计算退化因子。全局退化因子是系统准则矩阵的条件数。与以往的解决方法不同,本文提出用系统状态矩阵的解来形成系统的判据矩阵。利用外源信号的导数对系统的输出向量进行加性分解,实现了线性代数问题的解参数化,并考虑了系统的稳态模式。提出了连续多通道动态系统退化的先验估计方法。讨论了用模态控制方法实现系统准则矩阵退化所需值的方法。本文附有实例支持。

A method for streamlining state partitioning procedures with two and three outcomes is considered. A terminology and methods of the questionnaire theory were used, and the sequence of partitioning procedures itself was defined as a heterogeneous questionnaire with questions having two or three answers. This class of questionnaires is special and is defined by the authors as a class of binary-ternary questionnaires. This is the simplest class of heterogeneous questionnaires. An increase in number of answers to a question in practice can give an advantage in parameters of the questionnaires, including in the indicator of its effectiveness – the average implementation cost. It is noted that the use of binary-ternary questionnaires in practice can reduce the average time for identifying events on a questionnaire, which is extremely important in those applications of questionnaires in which there is a time limit for identifying events, for example, in critical application systems. A method for optimizing binary-ternary questionnaires is presented, based on the search for the most preferred questions for each subset of identifiable events. The choice of preferred questions is based on establishing a comparison relationship between them. The article describes all possible types of comparison relations between two questions with two answers, two questions with three answers, and also between a question with two answers and a question with three answers. An example of obtaining a mathematical expression for a function that characterizes the preference of questions over each other, as well as a generalized formula for choosing the most preferred question for any heterogeneous questionnaires is given. An algorithm has been formed for the method of ordering questions, which allows one to construct a binary-ternary questionnaire with the lowest implementation cost in polynomial time. An example of a binary-ternary questionnaire optimization by the presented method is given.
研究了一种具有两种结果和三种结果的状态划分过程的简化方法。采用问卷理论的术语和方法,将划分过程本身的顺序定义为具有两个或三个答案的异构问卷。这类问卷具有特殊性,作者将其定义为一类二元-三元问卷。这是最简单的一类异质性问卷。在实践中,对一个问题的回答数量的增加可以使调查表的参数具有优势,包括其有效性指标- -平均执行成本。值得注意的是,在实践中使用二元-三元调查表可以减少在调查表上确定事件的平均时间,这对于有确定事件时间限制的调查表应用,例如在关键应用系统中,是极其重要的。提出了一种优化二元三元问卷的方法,该方法基于对可识别事件的每个子集搜索最受欢迎的问题。首选问题的选择是建立在它们之间的比较关系的基础上的。这篇文章描述了所有可能类型的比较关系,两个问题有两个答案,两个问题有三个答案,以及一个问题有两个答案和一个问题有三个答案。给出了一个函数的数学表达式的例子,该函数表示问题对其他问题的偏好,以及为任何异构问卷选择最喜欢的问题的一般公式。提出了一种排序问题的算法,可以在多项式时间内以最低的实现成本构造二、三元问卷。给出了用该方法优化二元-三元问卷的一个实例。

Currently, there is a great interest in digital radio network centralized elements synchronization with random multiple access to the CSMA/CA type , the effectiveness of which determines the process of establishing a communication session. At the same time, there was no assessment effectiveness digital radio communication network centralized elements synchronization with random multiple access to the CSMA/CA type. Also, there was no assessment made the contribution of potential destructive actions by the attacker to the reduction in the effectiveness of such synchronization. This paper presents digital radio networks centralized elements synchronization analytical model with random multiple access to the CSMA/CA type medium. In this model the theoretical resulting indicator is the probability of successful delivery of a synchronization package, and a package frequency of successful delivery is used in experimental indicator evaluation . The model takes into account the potential destructive effects of the attacker in analytical expressions for known probabilistic indicators. An digital radio network  centralized elements synchronization with random multiple access to a CSMA/CA type experimental study an environment is also presented. The most common network of digital radio standard IEEE 802.11 (Wi-Fi) is considered as such network. The experimental research results differ from the theoretical research results slightly, which indicates the adequacy of the developed analytical model. It was established, firstly, that the successful delivery probability of a synchronization packet does not depend on number of subscriber terminals in digital radio communication networks, secondly, with an average duration of a data packet transmission by such terminal less than 0.85 ms, it is advisable to use non-random, and the reserved multiple access to the environment, and, thirdly, centralized synchronization is resistant to destructive influences. The model is applicable in the design of digital radio networks with random multiple access to the medium such as CSMA/CA, as well as in optimizing the operation of such networks.
目前,数字无线网络集中元同步随机多址的CSMA/CA类型引起了人们极大的兴趣,其有效性决定了通信会话的建立过程。同时,还没有对CSMA/CA型数字无线电通信网集中式元同步随机多址的有效性进行评估。此外,也没有评估攻击者的潜在破坏性行为对降低这种同步有效性的贡献。提出了随机多址访问CSMA/CA型介质的数字无线网络集中元同步分析模型。在该模型中,理论结果指标为同步包成功交付的概率,实验指标评价采用同步包成功交付的频率。该模型在已知概率指标的解析表达式中考虑了攻击者的潜在破坏性影响。提出了一种基于CSMA/CA的数字无线网络集中元同步随机多址的实验研究方法。最常见的网络数字无线电标准IEEE 802.11 (Wi-Fi)被认为是这样的网络。实验研究结果与理论研究结果略有差异,表明所建立的分析模型的充分性。首先,在数字无线电通信网络中,同步包的成功投递概率不依赖于用户终端的数量;其次,当用户终端传输数据包的平均持续时间小于0.85 ms时,建议采用非随机、预留的多址接入环境;第三,集中式同步具有抗破坏性影响的特点。该模型适用于CSMA/CA等随机多址数字无线网络的设计和网络运行优化。

An approach to the dynamic formation (adjustment) of schedules for distributed photogrammetric image processing in a network of ground centers included in the United geographically distributed information system for receiving and processing Earth remote sensing data from space is considered. Having the fullest satisfaction of requirements of consumers to the satellite images of necessary areas, the approach provides the formation of self-organizing B2B enterprises in the specified network providing information, software and hardware resources of the ground-based facilities of various departmental and other accessories for photogrammetric processing of any received images of the area from the the United geographically distributed information system. It is shown, that a search in B2B enterprise nodes and borrowing the required resources will allow ground centers to flexibly scale physical and virtual means of photogrammetric processing of Earth remote sensing data, quickly form their local structural and functional organizations depending on the current properties of the consumer requests flow for receiving Earth remote sensing data in the United geographically distributed information system, characteristics of the flow of terrain survey materials from orbital monitoring tools, and also take into account the visual and measuring properties of images of the area subject to photogrammetric processing. A method for truncating the set of potential performers of the application in accordance with the existing semantic and other restrictions on the composition of the desired set of performers is proposed. Also mechanisms to encourage ground centers to provide idle resources to B2B enterprise nodes are proposed. They are based on the possibility of receiving monetary or other remuneration from a ground center for participating in distributed application servicing. The development of a well-known model of a self-organizing B2B enterprise creates conditions for a more efficient organization of servicing the flow of applications in the United geographically distributed information system by attracting unused software, information and hardware resources of ground centers of various departmental affiliations.

Using bioinspired models and methods is one of approaches for solving tasks of swarm robotics. In this paper one of such tasks, modeling of foraging, and it’s solving by creating analogues of social structures of ants and models of feeding behavior are considered. The most important characteristics of ants’ colonies for modeling were defined – individuals number in society and it’s structure, workers’ speed, a communication distance and working area size. Besides, existing experimental basis (a group of robots and a polygon) was estimated for a usage as a hardware platform for experiments. Several models of feeding behavior were considered: a model without foragers’ functions differentiation and a model with differentiation on active and passive ones. Active foragers look for resources by themselves, then they involve passive foragers; passive foragers are settled on a base, while are not involved in harvesting. A set of finite state machines describe the behavior of agents: basic automatons (provide basic behavior functions) and a meta- automaton, that switches with some conditions an execution of basic automatons. Basic movements were tested on experimental basis. A complex test of models were conducted in a simulation program Kvorum. An analogue of real polygon was made in the program. Modeling consists of series of experiments for every model in which agents must harvest resources. Series differ from each other by number of agents. For models’ quality estimation a ratio of received energy to average obtaining time. Experiments settle that model with functions differentiation works more effective.
使用仿生模型和方法是解决群体机器人任务的途径之一。本文考虑了其中的一个任务,觅食建模,以及通过创建蚂蚁社会结构和觅食行为模型的类似物来解决这个问题。定义了蚁群建模中最重要的特征——群体数量及其结构、工蚁速度、沟通距离和工作区域大小。此外,估计了现有的实验基础(一组机器人和一个多边形)作为实验的硬件平台。研究了几种摄食行为模型:一种是没有觅食者功能分化的模型,一种是主动与被动分化的模型。主动觅食者自己寻找资源,然后涉及被动觅食者;被动采集者定居在基地上,不参与收割。一组有限状态机描述了代理的行为:基本自动机(提供基本行为功能)和元自动机(在某些条件下切换基本自动机的执行)。基本动作在实验基础上进行测试。在Kvorum仿真程序中对模型进行了复杂的测试。在程序中对真实多边形进行了模拟。建模包括对每个模型进行一系列的实验,agent必须在这些实验中获取资源。各个系列的代理商数量不同。对于模型的质量估计,是接收能量与平均获取时间的比值。实验证明,函数微分模型更有效。

In this paper we study one of the possible variants of smooth approximation of probability criteria in stochastic programming problems. The research is applied to the optimization problems of the probability function and the quantile function for the loss functional depending on the control vector and one-dimensional absolutely continuous random variable. In this paper we study one of the possible variants of smooth approximation of probability criteria in stochastic programming problems. The research is applied to the optimization problems of the probability function and the quantile function for the loss functional depending on the control vector and one-dimensional absolutely continuous random variable.  The main idea of the approximation is to replace the discontinuous Heaviside function in the integral representation of the probability function with a smooth function having such properties as continuity, smoothness, and easily computable derivatives. An example of such a function is the distribution function of a random variable distributed according to the logistic law with zero mean and finite dispersion, which is a sigmoid. The value inversely proportional to the root of the variance is a parameter that provides the proximity of the original function and its approximation. This replacement allows us to obtain a smooth approximation of the probability function, and for this approximation derivatives by the control vector and by other parameters of the problem can be easily found.  The article proves the convergence of the probability function approximation obtained by replacing the Heaviside function with the sigmoidal function to the original probability function, and the error estimate of such approximation is obtained. Next, approximate expressions for the derivatives of the probability function by the control vector and the parameter of the function are obtained, their convergence to the true derivatives is proved under a number of conditions for the loss functional. Using known relations between derivatives of probability functions and quantile functions, approximate expressions for derivatives of quantile function by control vector and by the level of probability are obtained. Examples are considered to demonstrate the possibility of applying the proposed estimates to the solution of stochastic programming problems with criteria in the form of a probability function and a quantile function, including in the case of a multidimensional random variable. 
本文研究了随机规划问题中概率准则光滑逼近的一种可能变体。研究了基于控制向量和一维绝对连续随机变量的损失泛函的概率函数和分位数函数的优化问题。本文研究了随机规划问题中概率准则光滑逼近的一种可能变体。研究了基于控制向量和一维绝对连续随机变量的损失泛函的概率函数和分位数函数的优化问题。近似的主要思想是将概率函数的积分表示中的不连续的Heaviside函数替换为具有连续性、光滑性和易于计算导数等性质的光滑函数。这种函数的一个例子是一个随机变量的分布函数,它按照logistic规律分布,具有零均值和有限色散,它是一个s型。与方差的根成反比的值是一个参数,它提供原始函数及其近似值的接近度。这种替换使我们能够获得概率函数的光滑近似值,并且对于这个近似值,可以很容易地找到由控制向量和由问题的其他参数的导数。本文证明了用s型函数代替Heaviside函数对原概率函数近似得到的概率函数近似的收敛性,并得到了该近似的误差估计。其次,得到了控制向量和函数参数对概率函数求导的近似表达式,证明了损失泛函在若干条件下收敛于真导数。利用已知的概率函数和分位数函数的导数关系,得到了分位数函数的导数按控制向量和按概率水平的近似表达式。本文考虑了一些例子,以证明将所提出的估计应用于具有概率函数和分位数函数形式的随机规划问题的解决的可能性,包括在多维随机变量的情况下。

Simulation Model of Electric Code-Modulated Signal in Russian Systems of Interval Control of Train Movement Based on Track Circuit 基于轨道电路的俄罗斯列车运行区间控制系统电码调制信号仿真模型
Q3 Mathematics Pub Date : 2019-09-19 DOI: 10.15622/sp.2019.18.5.1212-1238

Systems of interval control of train movement Signaling systems, which are currently in service in Russian railways, use the electric track circuit as the main data channel between signals and locomotives. Code-modulated electric signals transferred through that channel are frequently get corrupted which leads to railway traffic delays. Decoding of the electric signal received from a track circuit can be represented as an image classification problem, and thus the stability of the data channel could be significantly improved. However, to build such a classifier based on some machine learning algorithm, one needs a large dataset. In this article, a simulation model to synthesize this dataset is proposed. The structure of the computer model matches the main stages of the electric code-modulated signal generation in a track circuit: code signal generator, rails, locomotive receiver. Based on code signal generator schematic and waveform diagrams, a generator algorithm is developed. At this stage, we modeled timings of electric code signals according to the specification as well as their random deviations caused by various factors. The analysis of substitution circuits of the rail line revealed that it has the properties of a low-pass filter. So, the rail line using the Butterworth digital filter with corresponding parameters is modeled. Additionally, at this stage, random noise during transmission was taken into account. A similar technique is applied for modeling of a locomotive receiver which has a band-pass filter as the first signal processing block. Thus, the proposed simulation model consists of a set of algorithms which run in series. By varying the parameters of the model, one can synthesize waveform diagrams of the electric code-modulated signal received by the locomotive equipment from a track circuit working in various modes and conditions.
列车运行间隔控制系统信号系统是目前在俄罗斯铁路中使用的,它使用轨道电路作为信号与机车之间的主要数据通道。通过该信道传输的码调电信号经常被破坏,导致铁路交通延误。对轨道电路接收到的电信号进行解码可以表示为图像分类问题,从而可以显著提高数据通道的稳定性。然而,要基于某些机器学习算法构建这样的分类器,需要一个大的数据集。本文提出了一个综合该数据集的仿真模型。计算机模型的结构符合轨道电路中电码调制信号产生的主要阶段:码信号发生器、钢轨、机车接收机。根据编码信号发生器原理图和波形图,提出了一种编码信号发生器算法。在这一阶段,我们根据规范对电码信号的时序以及各种因素造成的随机偏差进行建模。通过对线路替代电路的分析,表明其具有低通滤波器的特性。因此,利用巴特沃斯数字滤波器对相应参数的轨道进行了建模。此外,在此阶段还考虑了传输过程中的随机噪声。将类似的技术应用于机车接收机的建模,该接收机以带通滤波器作为第一信号处理块。因此,所提出的仿真模型由一系列连续运行的算法组成。通过改变模型的参数,可以合成机车设备从轨道电路接收到的各种模式和条件下的电调码信号波形图。

The successful solution of practical cosmonautics problems is largely achieved by contemporary advances in measurement and computing technology, as well as by improvements in methods of primary and secondary processing of trajectory measurements. Therefore, in long-range programs of space exploration and space technology development, much attention is paid to improving existing and developing new algorithmic and technical means of navigation support for flights of space objects with the purpose to expand capabilities and increasing the efficiency of autonomous navigation systems of spacecraft, as well as ground-based and perspective orbital systems of space monitoring. Currently, active work is underway to modernize and develop promising complexes of specialized optoelectronic devices for monitoring near-Earth space based on angular measurements. The article considers the application of the variational approach for solving problems of statistical estimation of the trajectory parameters of the orbital object by angular measurements, which were carried out by ground-based optoelectronic means that are part of the modern space control system. Models and algorithms for determining estimates of orbital parameters that implement the variational version of the maximum likelihood method are presented, as well as the results of test calculations related to iterative solution of the two-point boundary value problem of variational estimation. The main purpose of the numerical calculations  is a study of convergence of the proposed estimation algorithm, as well as the impact of measurement errors on the displacement of the obtained estimates relative to their exact values. The simulation results, presented in the article, correspond to the conditions of the orbital motion of METEOR PRIRODA spacecraft and were obtained using the ephemeris data of the NORAD catalog in TLE-elements.

Concatenated Coding for Multilevel Flash Memory with Low Error Correction Capabilities in Outer Stage 外级低纠错能力多级快闪存储器的级联编码
Q3 Mathematics Pub Date : 2019-09-19 DOI: 10.15622/sp.2019.18.5.1149-1181

One of the approaches to organization of error correcting coding for multilevel flash memory is based on concatenated construction, in particular, on multidimensional lattices for inner coding. A characteristic feature of such structures is the dominance of the complexity of the outer decoder in the total decoder complexity. Therefore the concatenated construction with low-complexity outer decoder may be attractive since in practical applications the decoder complexity is the crucial limitation for the usage of the error correction coding. We consider a concatenated coding scheme for multilevel flash memory with the Barnes-Wall lattice based codes as an inner code and the Reed-Solomon code with correction up to 4…5 errors as an outer one. Performance analysis is fulfilled for a model characterizing the basic physical features of a flash memory cell with non-uniform target voltage levels and noise variance dependent on the recorded value (input-dependent additive Gaussian noise, ID-AGN). For this model we develop a modification of our approach for evaluation the error probability for the inner code. This modification uses the parallel structure of the inner code trellis which significantly reduces the computational complexity of the performance estimation. We present numerical examples of achievable recording density for the Reed-Solomon codes with correction up to four errors as the outer code for wide range of the retention time and number of write/read cycles.
多层快闪记忆体纠错编码的组织方法之一是基于串联结构,特别是基于多维格进行内部编码。这种结构的一个特征是外部解码器的复杂性在总解码器复杂性中占主导地位。因此,具有低复杂度外部解码器的串联结构可能具有吸引力,因为在实际应用中解码器的复杂度是使用纠错编码的关键限制。本文提出了一种以基于Barnes-Wall点阵的码为内码,以纠错率可达4 ~ 5的Reed-Solomon码为外码的多电平闪存级联编码方案。对具有非均匀目标电压电平和依赖于记录值的噪声方差(输入相关加性高斯噪声,ID-AGN)的闪存单元的基本物理特征的模型进行了性能分析。对于这个模型,我们开发了一种改进的方法来评估内部代码的错误概率。这种改进使用了内部代码网格的并行结构,大大降低了性能估计的计算复杂度。我们给出了里德-所罗门码可实现的记录密度的数值例子,在广泛的保留时间和写/读周期的数量范围内,作为外部代码,校正最多四个错误。
