The process in order for a future customer (household consumer or business consumer) to be connected to a gas network and address its energy needs requires a difficult, demanding and usually time-consuming sequence of steps. For this reason, both process optimization and minimization of administrative effort are issues of great importance for companies operating gas networks. The present study dealt with the optimization of the abovementioned process (New Customer Gas Connection) regarding a company operating as a natural gas network operator in Greece. For this purpose, interviews were conducted with the company's top management and employees in order to record the current situation (AS-IS) concerning the process. After the implementation of AS-IS analysis, existing process weaknesses were identified and an improved process was designed. At this point, the study introduced Industry 4.0 technologies, which are a developing and hot trend in the last decade, focusing on the use of sensors and actuators in order to automate a series of processes. Industry 4.0 is used mainly in industries, and its methodologies and tools have also been used in the gas industry. During the process reengineering (TO-BE), four Industry 4.0- related domains were identified, in which major improvements could be applied: the use of smart meters in order to measure gas consumption, the use of smart tags in order to manage the maintenance of gas equipment, the use of smart tags in order to control document traceability within the company and the coordination (integration) of the process using appropriate information systems. Based on the above, it is concluded that by using technologies and tools related to Industry 4.0, reorganizing processes and making a sensible investment, long-term savings can be achieved. In addition, the total duration of the process may be significantly reduced. The research effort should be continued by further analyzing more case studies which clarify the role and importance of managing and modeling business processes in conjunction with Industry 4.0, with the final aim of improving processes and performance of companies as a whole.
为了让未来的客户(家庭消费者或企业消费者)连接到天然气网络并解决其能源需求,这一过程需要一个困难、苛刻且通常耗时的步骤序列。因此,对于运营天然气网络的公司来说,流程优化和管理工作量最小化都是非常重要的问题。本研究涉及希腊一家天然气网络运营商公司的上述过程(新客户天然气连接)的优化。为此,与公司高层管理人员和员工进行了访谈,以记录有关该过程的现状。在实施AS-IS分析后,发现了现有流程的弱点,并设计了改进的流程。在这一点上,该研究介绍了工业4.0技术,这是过去十年发展和热门的趋势,重点是使用传感器和执行器来实现一系列流程的自动化。工业4.0主要应用于工业领域,其方法和工具也被用于天然气行业。在流程再造(将来)过程中,确定了四个与工业4.0相关的领域,其中可以应用重大改进:使用智能仪表来测量燃气消耗,使用智能标签来管理燃气设备的维护,使用智能标签来控制公司内部的文件可追溯性,以及使用适当的信息系统来协调(集成)流程。综上所述,通过使用与工业4.0相关的技术和工具,重组流程并进行合理的投资,可以实现长期的节省。此外,该过程的总持续时间可能会大大减少。研究工作应该通过进一步分析更多的案例研究来继续,这些案例研究阐明了与工业4.0相结合的管理和建模业务流程的作用和重要性,最终目标是改善整个公司的流程和绩效。

Development of Tactical Level AI for Melee and Range Combat 为近战和远程战斗开发战术级别AI
V. Gorshkov, A. Zagarskikh
The development of AI directly affects the emergence of new technologies. In modern video games, AI faces a wide range of tasks at various levels. The current situation is such that in addition to standard decision-making, to which the average player is casual, AI often has to do more complex things: to perceive the environment, interact with it, interact with the other AI, move in a complex three-dimensional space and other various tasks. Given the constant development of the gaming industry, the requirements for AI are constantly increasing. Therefore, there is the problem of AI flexibility. In video games, we can increasingly see how the battle of two NPCs turns into a simple search of teams to attack and defend. These primitives repel the player, destroying a decent part of the gameplay conceived by the developer. In the same way it is applicable to the visualization of historical events. For accurate reconstruction, it is necessary that the behavior of the agents be similar to human's behavior. In this paper, we give a brief review on some of well-known AI development methods, compare their effectiveness and present a new method of AI development that simulate the behavior of non- player character in melee and ranged combat based on the interaction of three levels: strategic, tactical and operational for decision-making. Combination of the well-known methods of AI development, base agent's model change and improvement in agent understanding of the environment by using the Voronoi diagram. The method proposed in this paper are showing significantly different results from the most popular design methods and the Utility-AI-Behavior Tree method, significantly reducing the distance in terms of key indicators such as survive time, use of useful resources, number of enemies killed. The used method imitates the player's actions, while excluding the human error factor and unexpected actions. The designed AI simulates the player's logical actions with a good accuracy, but is still more predictable than the real players. Mathematical calculations and the distribution of weights on each frame do not have a significant impact on performance, which allows simulating the behavior of many agents at once in one scenario, without losing performance and influencing the resulting sensations from the gameplay.
人工智能的发展直接影响着新技术的出现。在现代电子游戏中,AI面临着各种级别的广泛任务。目前的情况是,除了标准的决策(游戏邦注:一般玩家都很随意)之外,AI通常还需要做更复杂的事情:感知环境、与环境互动、与其他AI互动、在复杂的三维空间中移动以及其他各种任务。随着游戏行业的不断发展,对AI的要求也在不断提高。因此,存在人工智能灵活性的问题。在电子游戏中,我们可以越来越多地看到两个npc之间的战斗是如何变成一个简单的团队攻击和防御的过程。这些原语会让玩家反感,破坏了开发者构思的部分游戏玩法。同样,它也适用于历史事件的可视化。为了实现准确的重建,智能体的行为必须与人类的行为相似。本文简要回顾了一些著名的人工智能开发方法,比较了它们的有效性,并提出了一种新的人工智能开发方法,该方法基于战略、战术和决策操作三个层面的相互作用,模拟非玩家角色在近战和远程战斗中的行为。结合知名的人工智能开发方法,通过使用Voronoi图,改变基础智能体的模型,提高智能体对环境的理解。本文提出的方法与最流行的设计方法和效用-人工智能行为树方法的结果明显不同,在生存时间、有用资源的使用、杀死敌人的数量等关键指标上显著缩短了距离。所使用的方法模仿玩家的行动,同时排除人为错误因素和意外行动。设计出来的AI能够很准确地模拟玩家的逻辑行动,但仍然比真正的玩家更具可预测性。数学计算和每帧的权重分布对性能没有显著影响,这允许在一个场景中同时模拟许多代理的行为,而不会损失性能并影响游戏玩法的最终感觉。

Adaptive Multi-Parameter Prediction Model Based on Grey Theory 基于灰色理论的自适应多参数预测模型
Jie Jiang, Zhang Yan
Fault prediction is of great importance to ensuring weapon equipments' safety and reliability. Usually the data for fault detection and prediction of weapon equipments have features like small samples and multi-parameter. Currently the main fault prediction methods have achieved some success in practical applications, but all fall short at some aspects. Based on grey prediction theory and with analysis of disadvantages of GM(1, 1) model, an adaptive prediction model with several characteristic parameters for small samples is put forward. This model modifies initial value and background value, and takes interrelations of the parameters and characteristics of prediction series into account. The model is then used for prediction and analysis with the multi-parameter data of certain aero-engine. The results show that the model has good prediction precision, which in turn validates its availability.
故障预测对保证武器装备的安全可靠运行具有重要意义。通常用于武器装备故障检测和预测的数据具有小样本和多参数的特点。目前主要的故障预测方法在实际应用中取得了一定的成功,但在某些方面都存在不足。基于灰色预测理论,在分析GM(1,1)模型不足的基础上,提出了一种多特征参数的小样本自适应预测模型。该模型对初始值和背景值进行了修正,并考虑了各参数之间的相互关系和预测序列的特征。将该模型应用于某型航空发动机多参数数据的预测分析。结果表明,该模型具有较好的预测精度,验证了该模型的有效性。

Securitization and Criminalization of Migrants in Bosnia and Herzegovina 波斯尼亚和黑塞哥维那境内移徙者的证券化和刑事定罪
Armin Kržalić, Nedzad Korajlic, S. Dinarevic
The paper explores the nature and trend of migration during 2018, on the example of Bosnia and Herzegovina. The politicization of migrants' issues as well as a number of other factors contributed to the attitude of criminalization and securitization of migrants. Most authors and researchers dealing with the issue of migrants as well as the security representatives themselves argue that migrants are not a security threat to Bosnia and Herzegovina and that the state should treat them humanely and treat them according to international standards. In this paper we have determined that it is necessary to work on building additional capacities to accommodate migrants who have not found any accommodation or are on routes of Bosnia and Herzegovina, and that is important to undertake activities on technical, material and financial support for migration management in Bosnia and Herzegovina. We have used a qualitative research approach with the use of interview techniques and desk analysis for the purpose of collecting and processing primary and secondary data.
本文以波斯尼亚和黑塞哥维那为例,探讨了2018年移民的性质和趋势。移民问题的政治化以及一些其他因素促成了对移民的刑事定罪和证券化的态度。大多数处理移民问题的作者和研究人员以及安全代表本身都认为,移民对波斯尼亚和黑塞哥维那不是安全威胁,国家应该人道地对待他们,并按照国际标准对待他们。在本文件中,我们已经确定,必须努力建立额外的能力,以容纳没有找到任何住处或在波斯尼亚-黑塞哥维那路线上的移徙者,这对于开展为波斯尼亚-黑塞哥维那境内的移徙管理提供技术、物质和财政支助的活动是重要的。我们使用了定性研究方法,使用访谈技术和案头分析来收集和处理主要和次要数据。

Using Graph Representations for Semantic Information Extraction from Chinese Patents 基于图表示的中文专利语义信息提取
Wei Ding, Junli Wang, Haohao Zhu
This paper proposes a graph representation approach to automatically extract semantic information from Chinese patents, which can be used to provide semantic support for text-content based patent intelligent analysis. Two graph models are devised using graph representations, i.e., a keyword based text graph model and a dependency tree based text graph model. The first graph model is constructed by computing the similarities between two keywords, while the second graph model is constructed by extracting syntactic relations from text sentences. In the case study a frequent subgraph mining algorithm is utilized to discover frequent subgraph patterns based on the above two models, and such patterns were further used as features to build text classifiers for the purpose of testing the expressivity and effectiveness of the proposed graph models. The experimental results proves the validation of the proposed graph representation methods.
本文提出了一种自动提取中文专利语义信息的图表示方法,可为基于文本内容的专利智能分析提供语义支持。使用图表示设计了两种图模型,即基于关键字的文本图模型和基于依赖树的文本图模型。第一个图模型是通过计算两个关键词之间的相似度来构建的,第二个图模型是通过从文本句子中提取句法关系来构建的。在案例研究中,利用频繁子图挖掘算法在上述两种模型的基础上发现频繁子图模式,并将这些模式作为特征构建文本分类器,以测试所提出的图模型的表达能力和有效性。实验结果证明了所提出的图表示方法的有效性。

Raymund Herradura, F. Thabtah, M. Andrews
Data Visualisations have been identified to play a critical role in business decision making, wherein it acts as a bridge between decision makers and the vast amount of unstructured data. Blockchain applications are being carefully assimilated into the technological space due to Bitcoin's rapid rise in the financial market. Consequently, researchers, technologists and cryptocurrency investors can understand the posture of this technology that leads to articulate technological and financial investment strategies. This paper investigates the role of data analyses in the prominent implementation of Blockchain. We characterise the adoption of Blockchain technology by analysing two types of datasets which are text and multivariate by fitting multiple time series and geographical location to reveal unrealised opportunities for potential income and innovation. In addition, to obtain the useful trends over time a temporal data analyses to fit the Twitter dataset, was conducted. With the automated knowledge discovered this will supplement the decision makers' demand to have a valuable data-driven business strategy, which in return will deliver business or investment opportunities.
数据可视化在商业决策中起着至关重要的作用,它是决策者与大量非结构化数据之间的桥梁。由于比特币在金融市场的迅速崛起,区块链应用程序正在被仔细地吸收到技术领域。因此,研究人员、技术专家和加密货币投资者可以了解这项技术的现状,从而明确技术和金融投资策略。本文探讨了数据分析在区块链突出实施中的作用。我们通过分析文本和多变量两种类型的数据集来描述区块链技术的采用,通过拟合多个时间序列和地理位置来揭示潜在收入和创新的未实现机会。此外,为了获得随时间的有用趋势,进行了适合Twitter数据集的时间数据分析。随着自动化知识的发现,这将补充决策者对有价值的数据驱动业务战略的需求,这反过来将提供业务或投资机会。

A Comparison of Software Quality Characteristics and Software Sustainability Characteristics 软件质量特征与软件可持续性特征的比较
Sulaiman Aljarallah, R. Lock
Software sustainability has generated much interest in the software engineering field in recent times, and has been widely investigated across different fields and from different standpoints. The relationship between software quality and software sustainability is still an open question. In this study, a literature survey and comparison was conducted using three-phases, having as a starting point the comparison of basic models for software quality. A follow-up study, conducted at a more comprehensive level to cover both basic models and the most cited tailored models., Software sustainability literature is investigated to find the most frequent characteristics. Finally, data gathered from these studies and a comparison shows a similarity in the top level of these characteristics between software sustainability and software quality, and the emphasis on sustainability, maintainability and portability. The study suggests that ISO 25010 can be utilised by software sustainability. As a future work, the findings will be investigated empirically to support designing software sustainability framework identifying the most important criteria in the technical dimension.
近年来,软件可持续性在软件工程领域引起了很大的兴趣,并在不同的领域和不同的立场上进行了广泛的研究。软件质量和软件可持续性之间的关系仍然是一个悬而未决的问题。在本研究中,以比较软件质量的基本模型为出发点,分三个阶段进行文献调查和比较。后续研究,在更全面的层面上进行,涵盖基本模型和被引用最多的定制模型。研究了软件可持续性文献,找出了最常见的特征。最后,从这些研究中收集的数据和比较表明,软件可持续性和软件质量在这些特征的顶层是相似的,并且强调可持续性、可维护性和可移植性。研究表明,ISO 25010可用于软件可持续性。作为未来的工作,研究结果将进行实证调查,以支持设计软件可持续性框架,确定技术维度中最重要的标准。
