In the last decade, web-based applications have grown exponentially, especially with the wave of smart phones which has made both mobile and web applications accessible everywhere. This new revolution of internet played a major role in the growing complexity of today's software applications. Consequently, the quality assurance of such applications has become an inevitable feature for a web application to survive in such a highly competitive industry. Different methodologies have been proposed by the literature to test the quality of a system. Evaluating the test suite and improving the quality of the test sets is one of most known approaches used in the field. This technique is known as mutation testing. The purpose of this paper is to demonstrate the application of mutation testing technique on the widely used language in the development of web-based applications, JavaScript. Additionally, the paper will introduce a new approach to reduce the cost of mutation operators through the implementation of a novel taxonomy based on the blocks encapsulated within predicates.
在过去十年中,基于web的应用程序呈指数级增长,特别是随着智能手机的兴起,移动和web应用程序无处不在。互联网的这场新革命在当今日益复杂的软件应用程序中发挥了重要作用。因此,这些应用程序的质量保证已经成为web应用程序在竞争如此激烈的行业中生存的一个不可避免的特征。文献中提出了不同的方法来测试系统的质量。评估测试套件并提高测试集的质量是该领域最常用的方法之一。这种技术被称为突变测试。本文的目的是演示突变测试技术在基于web的应用程序开发中广泛使用的语言JavaScript上的应用。此外,本文将介绍一种新的方法,通过实现基于封装在谓词内的块的新分类法来降低突变操作符的成本。

This paper is devoted to the study of representation problem and use of experience in planning and implementing logistics projects in the field of e-business using geoinformation models. Geoinformation models can be presented as a description of the site of the territory on which the logistics project is implemented. The description consists of maps, charts and plans, as well as links to non-cartographic sources of information. The role of the quality criterion is considered as the reliability of the generated solutions. The reliability of the project is means the practical possibility of its implementation with minimal losses. Factors determining reliability in this sense are considered. The figurative representation of knowledge about the precedents of logistics projects is analyzed. Mapping of permissible transformations of the components of a logistics project in the form of cartographic objects is a distinctive feature of a figurative representation. Most often they are polygonal objects of location of logistics centers and transportation trajectories. The possibility of transferring an allowable transformation into another space-time domain with observance of topological constraints is considered as a way of preserving the meaning of the project. A method of transforming images into a given region of the territory is described. An example of a completed project with an estimate of reliability is given.
本文致力于研究利用地理信息模型在电子商务领域规划和实施物流项目中的表示问题和经验。地理信息模型可以作为对物流项目实施区域的描述来呈现。该描述包括地图、图表和计划,以及非制图信息来源的链接。质量准则的作用被认为是生成的解的可靠性。工程的可靠性是指工程在损失最小的情况下实施的实际可能性。在这个意义上考虑了决定可靠性的因素。分析了物流项目先例知识的形象化表示。以制图对象的形式对物流项目的组件进行允许的转换映射是具象表示的一个显著特征。大多数情况下,它们是物流中心位置和运输轨迹的多边形对象。在遵守拓扑约束的情况下,将允许的变换转移到另一个时空域的可能性被认为是保留项目意义的一种方式。描述了一种将图像转换为所述领土的给定区域的方法。给出了一个已完成工程的可靠性估计实例。

Currently, there is a tendency for collective use of Computer Aided Design of electronic circuits. As an information of similar systems that uses a database server that contains all the necessary background and design information that is accessible from the workstations. Therefore, the actual task is the development of integrated databases, electronic components, for both analog and digital circuits. Modern CAD systems support the electronic equipment, so called, the library design method. The essence of it lies in the fact that the development of an object is detailed to some elementary pieces, called structural primitives.

A data analysis system to extend the coverage capacity of meteorological stations for flood forecasting 建立数据分析系统,扩大气象站洪水预报的覆盖范围

Forecast Data provided by meteorological stations (MS) are crucial for Flood Forecasting Systems (FFS). These data are mainly related to temperature and precipitation. However, having enough MS to produce paramount of such data is challenging due to the high cost of their set up as well as their maintenance. As a consequence, it is almost impossible to get flood predictions in some regions due to the lack of meteorological forecast data. One solution to overcome such a drawback is to envision extending the data validity of a given area to another one. That is, we aim at using a MS of region A for estimating data we may have in region B if ever it had its own MS. In this respect, we propose an extension of MS forecast capacity by introducing a data analysis system based on a linear correlation technique. The system uses data collected from sensors networks installed on a given area not covered by a MS with data from a reference area that has a MS. Afterwards, it checks whether there is a linear correlation between the data of the two zones. In the affirmative case, a correlation function is deduced between the two areas and will be used for estimating data of the area without a MS. The results obtained from empiric experiments show the feasibility of our approach and its benefits.
气象站提供的预报数据对洪水预报系统至关重要。这些数据主要与温度和降水有关。然而,由于其设置和维护的高成本,拥有足够的MS来生成这些数据是具有挑战性的。因此,由于缺乏气象预报资料,一些地区几乎无法进行洪水预报。克服这种缺点的一个解决方案是设想将给定区域的数据有效性扩展到另一个区域。也就是说,我们的目标是使用区域a的质谱来估计我们在区域B中可能拥有的数据,如果它有自己的质谱的话。在这方面,我们建议通过引入基于线性相关技术的数据分析系统来扩展质谱预测能力。该系统将安装在没有MS覆盖区域的传感器网络收集的数据与具有MS的参考区域的数据相结合,然后检查两个区域的数据之间是否存在线性相关性。在肯定情况下,推导了两个区域之间的相关函数,并将其用于估计没有ms的区域的数据。经验实验结果表明了我们的方法的可行性和优点。

There is a large growing in the last years in using of mathematical modeling to analyze and predict the temperature distribution in the processing engineering. In this work, the analysis of temperature distribution during the sterilization of two liquid models in two dimensional cans was presented using computational fluid dynamics (CFD). The partial differential equations of continuity, energy, and momentum were solved numerically using a CFD software package (PHOENICS) version 3.5, which is based on finite volume method of analysis (FVM). All the physical properties of the liquid food used in this study were assumed constant except those for viscosity and density. The results of the simulations were presented in the form of transient temperature. The simulations show clearly the profile of temperature distribution during the whole process, the shapes and movement of the Slowest Heating Area (SHA), and the formation of the secondary flow..

Autonomous agents collaboration at run-time is a fundamental part of multi-agent oriented adaptive collaboration systems (ACSs) when an agent cannot accomplish a task by itself under changing environment. Such collaborations are usually regulated by commitment protocols, which are typically defined at design-time. However, agent commitments among the participants to meld collaborative patterns typically defined in static environments, which may not fit the need of ACSs. To address this, we propose a Goal-Capability-Commitment (GCC) based mediation for agents collaboration at run-time that combines invalid diagnoser, capability reconciliation and commitment compensation. We elaborate on each of GCC elements, focusing in particular on the feasibility afforded by (1) the ability to diagnose the failures of capability and commitment leaded by the changing environments, and (2) the ability of mediation to select appropriate capability or generate new commitment in order to satisfy the invalid goals. We represent the GCC model in a hospital medical waste AGV transportation case study and illustrate our approach through experiments.
运行时自治智能体协作是面向多智能体的自适应协作系统(ACSs)的一个基本组成部分,当一个智能体在不断变化的环境中不能单独完成任务时。这种协作通常由承诺协议来规范,而承诺协议通常是在设计时定义的。然而,参与者之间的代理承诺融合通常在静态环境中定义的协作模式,这可能不适合ACSs的需要。为了解决这个问题,我们提出了一个基于目标-能力-承诺(GCC)的中介,用于运行时的代理协作,该中介结合了无效诊断器、能力协调和承诺补偿。我们详细阐述了GCC的每个元素,特别关注以下方面的可行性:(1)诊断由变化的环境导致的能力和承诺失败的能力,以及(2)中介选择适当的能力或生成新承诺以满足无效目标的能力。我们将GCC模型应用于医院医疗废物AGV运输案例研究,并通过实验说明我们的方法。

Requirements traceability is an important quality factor in the life cycle of the software, there is a lot of software standards that demands his implementation, for example, ISO/IEC 29110, a standard for very small entities; however, projects of small organizations do not perform an adequate application of traceability. In the literature there are proposals with a high level of abstraction; the realization of a traceability information model for small software development organizations provides a narrow alternative, reducing the gap between the theory and the reality in software development. We present a traceability information model for small organizations within the framework of ISO/IEC 29110, in this way organizations access an illustrative and reusable traceability solution that allows them to improve the quality of software development. The article contemplates the definition of the models.
需求可追溯性是软件生命周期中一个重要的质量因素,有很多软件标准要求他实现,例如ISO/IEC 29110,一个针对非常小实体的标准;然而,小型组织的项目没有执行足够的可追溯性应用。在文献中,有一些具有高度抽象的建议;可追溯性信息模型的实现为小型软件开发组织提供了一个狭窄的选择,减少了软件开发中理论与现实之间的差距。我们在ISO/IEC 29110框架内为小型组织提供了一个可追溯性信息模型,通过这种方式,组织可以访问一个说明性和可重用的可追溯性解决方案,使他们能够提高软件开发的质量。本文考虑了模型的定义。

Use case is a model delivered by requirements engineering phase, which is considered as an input to the forthcoming design phase and test phase. A use case model is a simplest representation of an actor's interactions with the system in which the user is involved. The development of a use case model requires the finding out the use case itself and the actor that uses this use case to interact with the system. These two tasks are achieved manually via analyst's experience, who starts with different sources of data to develop use case model. User requirements document is a common source of data that may be started with to develop use case model. The extracting of actors and their actions (use cases) is subjected to the linguistic properties of each on. The aim of this paper is to define a new algorithmic approach for extracting actors and their use cases by using thematic role technique. This algorithmic approach had been manually tested using known examples, and shown its validity. The success of this technique will lead to develop an Intelligent Computer Aided Software Engineering (I-CASE) tool that automatically extracts actions and actors of use case model from functional requirements by using Semantic Role Labelling (SRL) of Natural Language Processing (NLP) approach.
用例是需求工程阶段交付的模型,它被认为是即将到来的设计阶段和测试阶段的输入。用例模型是参与者与用户所涉及的系统交互的最简单表示。用例模型的开发需要找出用例本身以及使用该用例与系统交互的参与者。这两个任务是通过分析人员的经验手动完成的,他们从不同的数据源开始开发用例模型。用户需求文档是用于开发用例模型的常用数据源。参与者及其行为(用例)的提取受制于每个参与者的语言属性。本文的目的是利用主题角色技术定义一种新的算法方法来提取角色及其用例。用已知的实例对该算法进行了人工测试,证明了其有效性。该技术的成功将导致智能计算机辅助软件工程(I-CASE)工具的开发,该工具通过使用自然语言处理(NLP)方法的语义角色标记(SRL),从功能需求中自动提取用例模型的动作和参与者。

A new data science framework for analysing and mining geospatial big data 用于分析和挖掘地理空间大数据的新数据科学框架

Geospatial Big Data analytics are changing the way that businesses operate in many industries. Although a good number of research works have reported in the literature on geospatial data analytics and real-time data processing of large spatial data streams, only a few have addressed the full geospatial big data analytics project lifecycle and geospatial data science project lifecycle. Big data analysis differs from traditional data analysis primarily due to the volume, velocity and variety characteristics of the data being processed. One of a motivation of introducing new framework is to address these big data analysis challenges. Geospatial data science projects differ from most traditional data analysis projects because they could be complex and in need of advanced technologies in comparison to the traditional data analysis projects.

地理空间大数据分析正在改变许多行业的企业运营方式。虽然文献中已经报道了大量关于地理空间数据分析和大空间数据流实时数据处理的研究工作,但涉及地理空间大数据分析项目全生命周期和地理空间数据科学项目生命周期的研究工作很少。大数据分析与传统数据分析的区别主要在于所处理数据的数量、速度和种类特征。引入新框架的动机之一是解决这些大数据分析的挑战。地理空间数据科学项目与大多数传统数据分析项目不同,因为与传统数据分析项目相比,它们可能很复杂,需要先进的技术。由于这个原因,必须有一个过程来管理项目,并确保项目参与者有足够的能力来执行这个过程。为此,本文提出了一种新的地理空间大数据挖掘和机器学习框架,用于地理空间数据采集、数据融合、数据存储、管理、处理、分析、可视化以及建模和评估。对于任何数据科学项目来说,拥有一个良好的数据分析过程和清晰的综合分析指南总是一个加分点。它还有助于在流程的早期预测所需的时间和资源,从而清楚地了解要解决的业务问题。

Although a good number of research works have reported in the literature on geospatial data analytics and real-time data processing of large spatial data streams, only a few have addressed the full geospatial big data analytics project lifecycle and geospatial data science project lifecycle. Big data analysis differs from traditional data analysis primarily due to the volume, velocity and variety characteristics of the data being processed. One of a motivation of introducing new framework is to address these big data analysis challenges. Geospatial data science projects differ from most traditional data analysis projects because they could be complex and in need of advanced technologies in comparison to the traditional data analysis projects.

In order to improve the Moroccan Health Emergency Services (HESs) at the regional level, we have established the HESs-RN (Regional Network) Geographic Information System (GIS) mapping on the basis of 1) proposing the structuring of HESs in the form of the HESs-RN modeled as a graph 2) modeling the HESs-RN by considering a medical emergency event as the Occurrence of events of Health Emergency (OHE), 3) proposing a Decision Support Model (DSM) to manage and control at best the different HESs-RN's OHE, and in particular to determine, in real time, the fastest path for the patient's transfer. This DSM supposes that the HES-RN nodes cooperate autonomously using best practices HES protocols and that they are regulated by the Health Emergency Assistance node.
为了在区域层面改善摩洛哥卫生应急服务(HESs),我们在以下基础上建立了HESs- rn(区域网络)地理信息系统(GIS)映射:1)提出HESs的结构,以HESs- rn的形式建模为图;2)通过将医疗紧急事件视为卫生紧急事件(OHE)的发生,对HESs- rn进行建模;3)提出决策支持模型(DSM),以最大限度地管理和控制不同HESs-RN的OHE,特别是实时确定患者转移的最快路径。本DSM假设HES- rn节点使用最佳实践HES协议自主合作,并由卫生紧急援助节点进行监管。
