Improved Spatio-temporal Kringing and its Application to Regional Precipitation Prediction 改进时空克林格及其在区域降水预测中的应用
Yan Liu, Ya-Di Hu, Haibo Wang, Can Jin, Dawei Dong
Precipitation is one of the most important elements in meteorological data. However, due to the limitation of resource conditions, the number of meteorological stations is limited, and interpolation is required to obtain the precipitation data in the observation area and other locations. Kriging interpolation whose core is to obtain the best variogram model is widely used in the prediction of regional precipitation. However, it is difficult to find perfect estimating model, and numerous approachs are utilized to handle this problem. In order to gain better parameters and model, an improved spatiotemporal Kriging interpolation method is proposed in this paper. The chaotic ant-lion algorithm (CALO) is employed to seek suitable parameters of the variogram both in the space domain and the time domain. This evolutionary algorithm whose performance has been validated in the literatures is not vulnerable to search the global solution. The experiment is conducted in terms of the fitting effect and interpolation effect, error analysis to demonstrate the superior performance of the proposed method, compared to other fitting methods such as Least square method. Several optimization algorithms are used to constitute the contrast experiment. The experimental results show that the proposed method prevails among other approachs as far as the precision, calculation cost and effectiveness.
降水是气象资料中最重要的要素之一。但由于资源条件的限制,气象站数量有限,需要插值获取观测区及其他位置的降水数据。Kriging插值在区域降水预报中得到了广泛的应用,其核心是获得最佳变差模型。然而,很难找到完美的估计模型,有许多方法被用来处理这个问题。为了获得更好的参数和模型,本文提出了一种改进的时空克里格插值方法。采用混沌蚁狮算法(CALO)在空间域和时间域寻找合适的变差函数参数。该进化算法不容易搜索全局解,其性能已被文献验证。从拟合效果、插值效果、误差分析等方面进行了实验,对比最小二乘法等其他拟合方法,验证了所提方法的优越性能。采用几种优化算法组成对比实验。实验结果表明,该方法在精度、计算成本和有效性方面优于其他方法。

Formal Description of Use Cases for Industry 4.0 Maintenance Processes Using Blockchain Technology 使用区块链技术的工业4.0维护过程用例的正式描述
Jan Stodt, Eugen Jastremskoj, C. Reich, Dominik Welte, A. Sikora
Maintenance processes in Industry 4.0 applications try to achieve a high degree of quality to reduce the downtime of machinery. The monitoring of executed maintenance activities is challenging as in complex production setups, multiple stakeholders are involved. So, full transparency of the different activities and of the state of the machine can only be supported, if these stakeholders trust each other. Therefore, distributed ledger technologies, like Blockchain, can be promising candidates for supporting such applications. The goal of this paper is a formal description of business and technical interactions between non-trustful stakeholders in the context of Industry 4.0 maintenance processes using distributed ledger technologies. It also covers the integration of smart contracts for automated triggering of activities.
工业4.0应用中的维护过程试图达到高质量,以减少机器的停机时间。对已执行的维护活动的监控是具有挑战性的,因为在复杂的生产设置中,涉及多个利益相关者。因此,只有在这些利益相关者相互信任的情况下,才能支持不同活动和机器状态的完全透明。因此,像区块链这样的分布式账本技术可能是支持此类应用程序的有希望的候选者。本文的目标是正式描述在使用分布式账本技术的工业4.0维护过程背景下,互不信任的利益相关者之间的业务和技术交互。它还涵盖了智能合约的集成,用于自动触发活动。

Abstract Model of Eavesdropper and Overview on Attacks in Quantum Cryptography Systems 量子密码系统中的窃听器模型及攻击概述
Zhengbing Hu, Yevhen Vasiliu, Oleksii Smirnov, V. Sydorenko, Yuliia Polishchuk
In today's world, it's almost impossible to find a sphere of human life in which information technologies would not be used. On the one hand, it simplifies human life – virtually everyone carries a mini-computer in his pocket and it allows to perform many operations, that took a lot of time, in minutes. In addition, IT has simplified and promptly developed areas such as medicine, banking, document circulation, military, and many other infrastructures of the state. Nevertheless, even today, privacy remains a major problem in many information transactions. One of the most important directions for ensuring the information confidentiality in open communication networks has been and remains its protection by cryptographic methods. Although it is known that traditional cryptography methods give reasons to doubt in their reliability, quantum cryptography has proven itself as a more reliable information security technology. As far is it quite new direction there is no sufficiently complete classification of attacks on quantum cryptography methods, in view of this new extended classification of attacks on quantum protocols and quantum cryptosystems is proposed in this work. Classification takes into account the newest attacks (which use devices loopholes) on quantum key distribution equipment. These attacks have been named «quantum hacking». Such classification may be useful for choosing commercially available quantum key distribution system. Also abstract model of eavesdropper in quantum systems was created and it allows to determine a set of various nature measures that need to be further implemented to provide reliable security with the help of specific quantum systems.
在当今世界,几乎不可能找到一个不使用信息技术的人类生活领域。一方面,它简化了人们的生活——几乎每个人的口袋里都装着一台微型电脑,它允许人们在几分钟内完成许多需要花费大量时间的操作。此外,信息技术还简化和迅速发展了医疗、银行、文件流通、军事等许多国家基础设施。然而,即使在今天,隐私仍然是许多信息交易中的一个主要问题。在开放通信网络中,保证信息机密性的一个重要方向一直是并且仍然是采用加密方法对信息进行保护。虽然传统的密码方法的可靠性令人怀疑,但量子密码已被证明是一种更可靠的信息安全技术。由于这是一个新的方向,目前对量子密码方法的攻击还没有足够完整的分类,鉴于此,本文提出了对量子协议和量子密码系统攻击的新的扩展分类。分类考虑了针对量子密钥分发设备的最新攻击(利用设备漏洞)。这些攻击被命名为“量子黑客”。这样的分类可能对选择商用量子密钥分配系统有用。此外,还建立了量子系统中窃听者的抽象模型,该模型允许确定一组需要进一步实施的各种性质措施,以帮助特定量子系统提供可靠的安全性。

Distributed Text Feature Selection Based On Bat Algorithm Optimization 基于Bat算法优化的分布式文本特征选择
Hongwe Chen, Qiao Hou, Lin Han, Zhou Hu, Z. Ye, Jun Zeng, Jiansen Yuan
The feature selection effect directly affects the classification accuracy of the text. This paper introduces a new text feature selection method based on bat optimization. This method uses the traditional feature selection method to pre-select the original features, and then uses the bat group algorithm to optimize the pre-selected features in binary code form, and uses the classification accuracy as the individual fitness. However, when the amount of text information is large, the execution time of the single machine is long. According to this shortcoming, combining the Bat Algorithm and the Spark parallel computing framework, the text feature selection algorithm SBATFS is proposed. The algorithm combines the good search performance of the bat algorithm with the distributed and efficient calculation speed to realize the efficient solution of the text feature selection optimization model. The results show that compared with the traditional feature selection method, after SBATFS is used for feature optimization, the classification accuracy is effectively improved.
特征选择的效果直接影响文本的分类精度。本文介绍了一种新的基于bat优化的文本特征选择方法。该方法采用传统的特征选择方法对原始特征进行预选择,然后利用bat群算法对预选择的特征以二进制编码形式进行优化,并以分类精度作为个体适应度。但是,当文本信息量较大时,单机执行时间较长。针对这一缺点,结合Bat算法和Spark并行计算框架,提出了文本特征选择算法SBATFS。该算法将bat算法良好的搜索性能与分布式高效的计算速度相结合,实现了文本特征选择优化模型的高效求解。结果表明,与传统的特征选择方法相比,采用SBATFS进行特征优化后,分类精度得到了有效提高。

A. Gozhyj, I. Kalinina, Victor Gozhyj, V. Vysotska
The investigation focuses on the use of Petri Nets for web services interaction modeling. It is discovered that Hierarchical Time Petri Nets is the most effective way to create web service interaction models. That is due to the fact that they can be used to build hierarchical models of complex systems, and investigate their dynamics. Moreover, the research describes a custom algebra-algorithmic system. It comprises the basis for further web services semantics and description. The models are developed with the custom algebra-algorithmic system operations. Service models are created with Petri colored nets. Models and imitational modeling are performed in the CPN-tools environment.

C. Chitu, G. Stamatescu, Iulia Stamatescu, V. Sgârciu
Dense distributed sensor systems deployed to monitor and control the built environment open up wide application areas for improving the quality of life through smart spaces. By implementing these systems in residential or commercial buildings, more efficient, pervasive, real-time and finally more robust decision support is achieved. As one of the key tasks, high accuracy occupancy detection and estimation within buildings offers the potential to improve HVAC utilization while reducing maintenance needs, enhancing energy savings for building operators as well as a more suitable thermal comfort for occupants. In this context the main contribution of the paper consists of an assessment of supervised machine learning techniques namely random forests and extreme machine learning neural networks for indirect occupancy profile estimation. The methods are applied on a benchmarking dataset of indoor carbon dioxide measurements and ventilation damper positions as collected from the building information system. The impact of data preprocessing through filtering and smoothing as well as hardware constraints and cloud distributed processing for algorithm deployment are also discussed. We highlight key challenges and discuss how the learned models can be integrated for online operation to improve energy efficiency.

R. Avanzato, F. Beritelli, Francesco Di Franco, Valerio Francesco Puglisi
The recent climatic changes imply an increasing manifestation of calamitous phenomena related to important hydrogeological disruptions in many parts of the earth. For this reason, an accurate estimate of rainfall levels becomes essential to be able to warn of the imminent occurrence of a calamitous event and reduce the risk to human beings. This paper proposes an approach based on Convolutional Neural Networks (CNN) to the classification of the audio signal coming from a new rainfall system.

Peculiarities of Human Machine Interaction for Synthesis of the Intelligent Dialogue Chatbot 智能对话聊天机器人合成中人机交互特性研究
I. Sidenko, G. Kondratenko, Pavlo Kushneryk, Y. Kondratenko
Research in the field of human machine interaction and machine learning contributed to the revival of the chatbots. They are virtual interlocutors whose logical apparatus is based on artificial intelligence. However, recent reviews show that chatbots are perceived as unwise systems. These results contributed to the rapid introduction of chatbots in social networks. At the same time, the question of choosing the structure of a neural network for learning dialogue systems, the principles and features of human machine interaction remains important. In this paper various architectures of neural networks are being compared, and it's own chatbot using encoder-decoder architecture with attention mechanism is developed. For implementation, the Python programming language is used. TensorFlow framework is used for deep learning. The simulation results confirm the effectiveness of the proposed approach to speech recognition and human machine interaction.
人机交互和机器学习领域的研究促进了聊天机器人的复兴。他们是虚拟的对话者,他们的逻辑装置是基于人工智能的。然而,最近的评论显示,聊天机器人被认为是不明智的系统。这些结果促成了聊天机器人在社交网络中的快速引入。同时,选择神经网络的结构、人机交互的原理和特征来学习对话系统仍然是一个重要的问题。本文对各种神经网络结构进行了比较,并开发了一种基于注意机制的编码器-解码器结构的聊天机器人。对于实现,使用Python编程语言。TensorFlow框架用于深度学习。仿真结果验证了该方法在语音识别和人机交互方面的有效性。

The paper proposes a new approach to compression and data transmission in Internet of Things environment, based on the transformation of the Residue Number System and the method of arithmetic coding. The transformation of the Residue Number System is used to divide the data into parts. As a result, the received remainders are compressing in parallel used the arithmetic coding. Then they are transmitting through parallel routes, if the last ones are present. The proposed approach improves the processing speed through the parallel work and provides a compression ratio of depending on the type of data.
本文提出了一种基于剩余数系统变换和算术编码方法的物联网环境下数据压缩与传输的新方法。利用剩余数系统的变换将数据分成若干部分。因此,接收到的余数使用算术编码并行压缩。如果最后一条线路还存在,它们就会通过平行的线路传播。该方法通过并行工作提高了处理速度,并提供了与数据类型相关的压缩比。
