On the use of probabilistic model-checking for the verification of prognostics applications 关于使用概率模型检查来验证预测应用
J. Aizpurua, V. Catterson
Prognostics aims to improve asset availability through intelligent maintenance actions. Up-to-date remaining useful life predictions enable the optimization of maintenance planning. Verification of prognostics techniques aims to analyze if the prognostics application meets the design requirements. Online prognostics applications depend on the data-gathering hardware architecture to perform correct prognostics predictions. Accordingly, when verifying prognostics requirements compliance, it is necessary to include the effect of hardware failures on prognostics predictions. In this paper we investigate the use of formal verification techniques for the integrated verification of prognostics applications including hardware and software components. Focusing on the probabilistic model-checking approach, a case study from the power industry shows the validity of the proposed framework.
预测旨在通过智能维护行动提高资产可用性。最新的剩余使用寿命预测可以优化维护计划。预测技术验证的目的是分析预测应用是否满足设计要求。在线预测应用程序依赖于数据收集硬件架构来执行正确的预测预测。因此,在验证预测需求遵从性时,有必要在预测预测中包括硬件故障的影响。在本文中,我们研究了使用形式化验证技术对包括硬件和软件组件在内的预测应用程序进行集成验证。针对概率模型检验方法,电力行业的一个案例研究表明了该框架的有效性。

Design and implementation of a targeted advertising system based on an audience recognition scheme for Smart TV 基于受众识别方案的智能电视定向广告系统的设计与实现
Cheonin Oh, K. Han
This paper1 suggests a targeted advertising system using an audience recognition technique suitable for a Smart TV environment. The proposed system detects different viewers in front of a TV and provides different advertisements depending on the detection results. Audience recognition consists of procedures for detecting the face area and features, as well as an identification procedure; in addition, based on the results of the recognition, the viewing behaviors are extracted. In regard to the extraction of the face area and the facial features, algorithms for a fast and precisely trace even when the face is rotated, and for measuring the rotating angle of the face and the open-close status of the eyes, are described. All recognition procedures were designed by considering the viewing distance and changes in lighting. In addition, a practical targeted advertising service and various other measurement indexes related to advertising effectiveness, along with an example application used to control the equipment and content by applying identification information of the recognized audience and their viewing behavior information, are represented.
本文提出了一种使用适合智能电视环境的受众识别技术的目标广告系统。该系统可以检测电视机前的不同观众,并根据检测结果提供不同的广告。受众识别包括检测面部区域和特征的程序,以及识别程序;此外,基于识别结果,提取了观看行为。关于面部区域和面部特征的提取,描述了即使在面部旋转时也能快速精确跟踪的算法,以及用于测量面部旋转角度和眼睛的开合状态的算法。所有识别程序的设计都考虑了观看距离和光照的变化。此外,还介绍了一种实用的定向广告服务和与广告有效性相关的各种其他测量指标,以及通过应用被识别的受众的识别信息及其观看行为信息来控制设备和内容的示例应用。

Conceptual ontology of prospective risk analysis in medical environments - the OPT-Model-Ontology 医学环境中前瞻性风险分析的概念本体- opt模型本体
Timo Sigwarth, K. Loewe, Eberhard Beck, Lutz Pelchen, T. Schrader
Clinical processes tend to be highly complex which results in 5%-10% erroneous procedures. A process risk analysis through the medical risk management is mostly retrospectively, therefore it's commonly not suited to prevent errors before occurring. In technical domains prospective analysis methods, like Hazards & Operability study (HAZOP study), are widely used, but the adaption of these methods for medical processes is rather difficult.
临床过程往往非常复杂,导致5%-10%的错误操作。通过医疗风险管理进行的过程风险分析大多是回顾性的,因此通常不适合在错误发生之前进行预防。在技术领域,前瞻性分析方法,如危害与可操作性研究(HAZOP研究)被广泛使用,但这些方法在医疗过程中的适应是相当困难的。

Simulated humanoid robots for e-learning 用于电子学习的模拟人形机器人
Hans-Dieter Burkhard
Robots will change our life dramatically. People are interested to know more about Robotics and AI. Teaching has to regard these developments. While learning by doing has great advantages, experimenting with real robots is limited by the available resources: Complex hardware is costly, and it needs time and experience for setup and maintenance. Simulated robots can be used as alternative. Our RoboNewbie project is a basic framework for experimenting with simulated robots. It serves as an inspiration for beginners, and it provides room for many challenging experiments. The RoboNewbie agents run in the simulation environment of SimSpark RCSS, the official RoboCup 3D simulator, where the simulated robots are models of the humanoid Robot NAO of the French Company Aldebaran. Different example agents provide easily understandable interfaces to simulated sensors and effectors of the robot as well as simple control structures. The framework has been successfully used at different courses where the participants needed only few hours to understand the usage of the framework and to develop own agents for different tasks.
机器人将极大地改变我们的生活。人们有兴趣更多地了解机器人和人工智能。教学必须考虑到这些发展。虽然边做边学有很大的优势,但用真正的机器人进行实验受到可用资源的限制:复杂的硬件成本很高,而且需要时间和经验来进行设置和维护。模拟机器人可以作为替代方案。我们的RoboNewbie项目是一个模拟机器人实验的基本框架。它为初学者提供了灵感,并为许多具有挑战性的实验提供了空间。RoboNewbie代理在官方机器人世界杯3D模拟器SimSpark RCSS的模拟环境中运行,其中模拟的机器人是法国公司Aldebaran的人形机器人NAO的模型。不同的示例代理提供了易于理解的接口来模拟机器人的传感器和效应器以及简单的控制结构。该框架已经成功地用于不同的课程,参与者只需要几个小时就可以理解框架的用法,并为不同的任务开发自己的代理。

Intensionality, compositionality, and nominativity in information system development 信息系统开发中的集约性、组合性和主体性
M. Nikitchenko
Summary form only given. Process of information system development consists of several phases including, in particular, system analysis, specification, design, and implementation. Each of these phases is based on some abstractions that can be roughly divided into two groups of general and specific abstractions respectively. In this talk we address to such general abstractions as intensionality, compositionality, and nominativity. Intensionality is understood in the traditional sense as a counterpart to extensionality that together complete each other and define the main aspects of notions in their integrity. Compositionality means that a system is constructed of smaller subsystems with the help of special construction operations called compositions. Nominativity emphasizes the importance of naming relations for system aspects description. We analyze and illustrate the use of the above mentioned abstractions in different phases of system development. Considering conventional mathematical formalisms we admit that they are based on the extensionality principle that restricts and complicates usage of such formalisms in system development. Therefore we construct formal mathematical structures based on the principles of intensionality, compositionality, and nominativity. These structures can be considered generalizations of traditional notions of algebras and logics for classes of "dynamic" data and functions. Introduction of such formalisms permits us to define also a special kind of intensionalized computability that better reflects specifics of executable components of information systems. We compare the constructed formalisms with the existing ones and demonstrate that they a rather expressive and more adequate for information system development.
只提供摘要形式。信息系统开发过程包括几个阶段,特别是系统分析、规范、设计和实现。这些阶段中的每一个都基于一些抽象,这些抽象可以大致分为两组,分别是一般抽象和特定抽象。在这次演讲中,我们将讨论诸如密集性、组合性和主性等一般抽象概念。在传统意义上,密集性被理解为外延性的对应物,它们共同完成彼此,并在其完整性中定义概念的主要方面。组合性意味着系统是由较小的子系统在称为组合的特殊构造操作的帮助下构造的。命名性强调命名关系对系统方面描述的重要性。我们分析并说明了上述抽象在系统开发的不同阶段的使用。考虑到传统的数学形式,我们承认它们是基于可扩展性原则的,这限制了系统开发中这种形式的使用并使其复杂化。因此,我们基于密集性、组合性和主性原则来构建形式化的数学结构。这些结构可以被认为是“动态”数据和函数类的代数和逻辑的传统概念的推广。这种形式化的引入允许我们定义一种特殊类型的强化可计算性,它更好地反映了信息系统可执行组件的具体情况。我们将构造的形式化与现有的形式化进行比较,并证明它们更具有表现力,更适合于信息系统开发。

A hybrid recommendation model for web navigation 一种用于网页导航的混合推荐模型
Dr Noaman M. Ali, A. Gadallah, H. Hefny
Nowadays, users rely on the web for information gathering. Accordingly, web usage mining becomes one important subject of research. Such research area covers prediction of user near future intentions, web-based personalized services, customer profiling, and adaptive web sites. Web page prediction is strongly limited by the nature of web logs, the intrinsic complexity of the problem and the tight efficiency requirements. This paper proposes a hybrid page ranking model based on web usage mining technique by exploiting session data of users, to enhance the recommendations of the next candidate web page to be accessed. The proposed approach represents a combination between two page ranking approaches. The first one computes the frequency ratio indicating the number of occurrences of each page in the search result. On the other hand, the second approach computes the coverage ratio from similar behavior patterns. As a result of the proposed approach, a set of candidate pages are ranked and the page with highest rate is recommended. The proposed approach has been tested on real data collected and extracted from the web server log file of CTI main web server.
如今,用户依靠网络来收集信息。因此,网络使用挖掘成为一个重要的研究课题。这些研究领域包括用户近期意图预测、基于web的个性化服务、客户分析和自适应网站。网页预测受到Web日志的本质、问题的内在复杂性和严格的效率要求的强烈限制。本文提出了一种基于web使用挖掘技术的混合页面排序模型,利用用户会话数据来增强下一个候选网页的推荐。所提出的方法是两种页面排序方法的结合。第一个计算频率比,表示每个页面在搜索结果中出现的次数。另一方面,第二种方法根据相似的行为模式计算覆盖率。根据所提出的方法,对一组候选页面进行排名,并推荐率最高的页面。该方法已在CTI主web服务器的web服务器日志文件中采集和提取的真实数据上进行了测试。

On biclustering of gene expression data 基因表达数据的双聚类研究
Mahmoud Mounir, M. Hamdy
The problem of finding groups of co-regulated genes is considered one of the major challenges in the analysis of gene expression data. Biclustering may be considered as one of the main techniques to analyze these data. Biclustering is a non-supervised technique outperforms the traditional clustering techniques because it can group both genes and conditions in the same time. A gene or condition may belong to more than one bicluster and hence to more than biological function or process. In this survey, we introduced some definitions of the biclustering with its mathematical model after that we reviewed some biclustering techniques based on the type of biclusters they can find; finally a set of validation measures were introduced to validate the biclustering techniques emphasizing the biological measures.
寻找共调控基因群的问题被认为是基因表达数据分析中的主要挑战之一。双聚类可以看作是分析这些数据的主要技术之一。双聚类是一种优于传统聚类技术的无监督聚类技术,因为它可以同时对基因和条件进行分组。一个基因或状况可能属于多个双聚类,因此涉及多个生物功能或过程。本文首先介绍了双聚类的一些定义及其数学模型,然后根据它们所能找到的双聚类的类型回顾了一些双聚类技术;最后介绍了一组验证措施来验证强调生物措施的双聚类技术。

Automated text document categorization 自动文本文档分类
R. Yasotha, E. Charles
During the last two decades the number of text documents in digital form has grown enormously. It is necessary to categorize documents into topics and sub topics for easy retrieval. Manual categorization of text documents can be done only by experts and it is a time consuming task. As a consequence, it is of great practical importance to be able to automatically organize and classify documents. There are two approaches, rule-based and machine learning-based, that are used to automate classification task. Both have some limitations. Rules may conflict each other and have to be reconstructed when a target domain changes, are such two limitations in the rule based approaches. Machine learning approaches require proper training data and they do not accountable with the classification results. Motivated by such limitations, this paper proposes a Latent Dirichlet Allocation (LDA) based approach to automatically classify text documents. In order to develop and test the proposed approach on a realistic set up, ACM (Association for Computing Machinery) Computing Classification System (CCS) is selected as the target platform and 9100 computer science related articles categorized under ACM-CCS were selected. The experimental results show that the proposed approach is effective for classifying text documents and is applicable to a domain with large number of categories in multiple levels.
在过去的二十年中,数字形式的文本文档的数量有了巨大的增长。为了便于检索,有必要将文档分为主题和子主题。文本文档的手动分类只能由专家来完成,并且是一项耗时的任务。因此,能够自动组织和分类文档具有重要的实际意义。有两种方法,基于规则和基于机器学习,用于自动分类任务。两者都有一定的局限性。规则可能会相互冲突,并且在目标域发生变化时必须重新构建,这是基于规则的方法中的两个限制。机器学习方法需要适当的训练数据,它们不负责分类结果。基于这种局限性,本文提出了一种基于潜在狄利克雷分配(Latent Dirichlet Allocation, LDA)的文本文档自动分类方法。为了在现实环境中开发和测试所提出的方法,选择ACM(美国计算机协会)计算分类系统(CCS)作为目标平台,并选择了在ACM-CCS下分类的9100篇计算机科学相关文章。实验结果表明,该方法对文本文档分类是有效的,适用于分类数量多、层次多的领域。

Efficient distributed dynamic graph system 高效的分布式动态图形系统
Aya Zaki, M. Attia, Doaa Hegazy, S. Amin
Research has focused on static large graph management. However, most of real-world networks evolve with time. Managing these evolving networks has attracted much attention in recent years. The networks' evolved data can be kept in a dynamic graph to improve the expressiveness and the quality of search queries as well as snapshot(s) retrieval. Storing the continuous evolution of the network in a dynamic graph makes its storage size grow. Existing dynamic graph models try to limit their storage by eliminating redundant data. However, their update time increases due to the elimination step. This illustrates that there is a tradeoff between the used storage and the update time. In this work, we address the problems of improving the update time of the networks' evolved data without increasing the storage redundancy as well as minimizing the needed memory storage. This paper merges the materialization technique with the distributed graph over servers. This merge reduces the update time and minimize the needed memory storage in an efficient manner as well as providing results with a better quality.
研究的重点是静态大图形管理。然而,大多数现实世界的网络都是随着时间而发展的。近年来,管理这些不断发展的网络引起了人们的广泛关注。网络进化的数据可以保存在一个动态图中,以提高搜索查询的表现力和质量,以及快照检索。将网络的连续演化以动态图的形式存储,使得网络的存储量不断增大。现有的动态图模型试图通过消除冗余数据来限制其存储。然而,由于消除步骤,它们的更新时间增加了。这说明在使用的存储和更新时间之间存在权衡。在这项工作中,我们解决了在不增加存储冗余的情况下提高网络进化数据更新时间以及最小化所需内存存储的问题。本文将物化技术与服务器分布式图技术相结合。这种合并减少了更新时间,并以一种有效的方式最大限度地减少了所需的内存存储,并提供了质量更好的结果。

This merge reduces the update time and minimize the needed memory storage in an efficient manner as well as providing results with a better quality.","PeriodicalId":6478,"journal":{"name":"2015 IEEE Seventh International Conference on Intelligent Computing and Information Systems (ICICIS)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87231396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Identification and prioritization of stakeholders in the planning process of sustainable development of the smart city 智慧城市可持续发展规划过程中利益相关者的识别和优先排序
Inete Ielite, G. Olevsky, Timurs Safiuļins
The article analyzes stakeholders in the city, conducted in order to identify organisations of particular value to the creation and delivery of the sustainable energy policy for smart cities i.e. enhanced Sustainable Energy Action Plan (SEAP). Using the information gathered in the stakeholder analysis, Riga, the capital of Republic of Latvia, has created a stakeholder engagement plan to gather and coordinate the key stakeholders' resources and knowledge for the benefit of the city, and for the development, implementation, monitoring and ongoing revision of the energy policy for the smart city i.e. SEAP. Different approaches to stakeholder communication and engagement planning have been used, based on specific city context, including history of engagement and current plans and ambitions. Riga stakeholders have been identified and prioritised using a matrix tool, allowing stakeholders to be grouped according to their importance for the enhanced SEAP and level of interest or engagement in the city. Riga has completed public consultation roundtables on its enhanced SEAP. Key stakeholders and their groups that have been identified include academia, local and regional administrations, industry and commerce, finance, energy suppliers and citizens. Riga working to engage all relevant stakeholder groups to help them move towards smart city status - including information and communication technology (ICT) partners, innovation bodies and international companies - in the process of developing and implementing the enhanced SEAP. As a result the city is making connections between players of energy, transport and ICT and increasing their role in CO2 emissions' reduction, and recognising opportunities of cross-sectoral actions and transfer of the best practice projects in synchrony with relevant local stakeholders, international companies and banks to roll out innovative sustainable energy solutions at a scale. Gaps in current stakeholder communication have also been identified, including insufficient recognition of job creation potential by engaging employment agencies, closer engagement with the transport sector companies, ensuring sufficient citizens' engagement, and building on existing relationships with ICT players. Riga has developed communication tools and stakeholder engagement plan based on analysis of the know-how and resources held by each of the stakeholders or their groups and their role in, and potential impact on the SEAP. With increasingly limited local authority resources for communication with stakeholders, usual methods and channels, based on ICT including newsletters, and emails, social media, have been prioritised in order to secure information flow and feedback from stakeholders.
本文分析了城市中的利益相关者,旨在确定对智能城市可持续能源政策的创建和交付具有特殊价值的组织,即增强的可持续能源行动计划(SEAP)。利用在利益相关者分析中收集的信息,拉脱维亚共和国首都里加创建了一个利益相关者参与计划,以收集和协调主要利益相关者的资源和知识,以造福城市,并为智能城市(即SEAP)的能源政策的制定、实施、监测和持续修订。根据具体的城市背景,包括参与历史和当前的计划和目标,使用了不同的利益相关者沟通和参与规划方法。使用矩阵工具确定了里加的利益相关者并对其进行了优先排序,允许利益相关者根据其对加强SEAP的重要性以及对城市的兴趣或参与程度进行分组。里加已经完成了关于加强SEAP的公众咨询圆桌会议。已确定的主要利益相关者及其团体包括学术界、地方和区域行政部门、工商业、金融、能源供应商和公民。里加致力于让所有相关的利益相关者团体——包括信息和通信技术(ICT)合作伙伴、创新机构和国际公司——在制定和实施增强的SEAP的过程中,帮助他们迈向智慧城市的地位。因此,该市正在将能源、交通和信息通信技术的参与者联系起来,提高他们在减少二氧化碳排放方面的作用,并认识到跨部门行动的机会,并与相关的当地利益相关者、国际公司和银行同步转让最佳实践项目,以大规模推出创新的可持续能源解决方案。还发现了当前利益相关者沟通方面的差距,包括没有充分认识到就业机构创造就业的潜力,与运输部门公司进行更密切的接触,确保公民的充分参与,以及建立与信息通信技术参与者的现有关系。里加根据对每个利益攸关方或其团体所掌握的知识和资源及其在SEAP中的作用和潜在影响的分析,制定了沟通工具和利益攸关方参与计划。由于地方当局与利益攸关方沟通的资源日益有限,因此优先考虑基于信息通信技术的常规方法和渠道,包括通讯、电子邮件、社交媒体,以确保信息流动和利益攸关方的反馈。
