一种集成的统一建模语言框架

Mohammad ALSHAYEB,Nasser KHASHAN,Sajjad MAHMOOD

《信息与电子工程前沿（英文）》 2016年第17卷第2期页码 143-159 doi: 10.1631/FITEE.1500094

摘要：

The unified modeling language (UML) is one of the most commonly used modeling languages in the software industry.It simplifies the complex process of design by providing a set of graphical notations, which helps express the objectoriented analysis and design of software projects. Although UML is applicable to different types of systems, domains, methods,and processes, it cannot express certain problem domain needs. Therefore, many extensions to UML have been proposed. In this paper, we propose a framework for integrating the UML extensions and then use the framework to propose an integrated unified modeling language-graphical (iUML-g) form. iUML-g integrates the existing UML extensions into one integrated form. This includes an integrated diagram for UML class, sequence, and use case diagrams. The proposed approach is evaluated using a case study. The proposed iUML-g is capable of modeling systems that use different domains.

UML状态图的机械语义和精化研究 Article

Feng SHENG, Liang DOU, Zong-yuan YANG

《信息与电子工程前沿（英文）》 2017年第18卷第11期页码 1773-1783 doi: 10.1631/FITEE.1601196

摘要： UML（Unified Modeling Language）是业界建模与分析的事实标准。然而，由于UML的语义信息未被精确定义，我们无法对UML模型之间的精化关系进行验证。本文使用定理证明器Coq形式定义了UML状态图的语义和模型之间的精化关系，形成机械语义。基于机械语义，模型语义信息及精化关系可以被描述为谓词及定理，在定理证明器Coq中进行证明。

主动虚拟服务器和网上数据集成的新模式

何新贵,杨良怀,唐世渭,杨冬青,陈立军,张震,林斌

《中国工程科学》 2001年第3卷第5期页码 55-60

摘要：

针对Internet上信息搜索和数据集成存在的问题，提出了“主动虚拟服务器”的概念，并给出了基于这种虚拟服务器的数据集成模式。主动虚拟服务器可认为是网上海量数据统一的存储和处理器，而且具有主动服务的功能。在不改变服务器中原DBMS的前提下，只需用一种统一的可扩展语言UXL为各种服务器做一件外观统一的“主动服务外套”，就可构成所需的"主动虚拟服务器"。上述"外套"对每种服务器只需实现一次，就能在整个网上统一使用，因此，它可在网上起到与Java虚拟机类似的作用。

Dymola-based multi-parameters integrated optimization for high speed transfer system of LED chip sorter

Jie OUYANG, Bin LI, Shihua GONG

《机械工程前沿（英文）》 2013年第8卷第2期页码 118-126 doi: 10.1007/s11465-013-0253-y

摘要：

To enhance the performance of high speed transfer system of LED chip sorting equipment, its control parameters need to be well matching with the mechanical system. In practical issues, it is difficult and time-consuming work to get these parameters matched because their selection is strongly depended on individuals. In current work, an integrated optimization method was carried out to solve this problem, in which the multiple control parameters optimization, modeling and simulation were included, i.e., a multi-domain model of transfer system performed on Dymola platform. Based on this model, the searching area of the key control parameters was narrowed by performing integrated optimization. After that a group of parameters were selected from this narrowed area to perform the equipment’s controls. The result showed this method possesses a simple and reliable nature. The optimal solutions also indicated that the optimized control parameters can well satisfy the requirements of transfer system. On the other hand, it greatly reduced the engineering adjustment time by using this method.

《工程（英文）》 2023年第29卷第10期页码 188-197 doi: 10.1016/j.eng.2023.03.017

摘要：

再生混凝土作为一种低碳混凝土，成为近20年来国内外的研究热点，但是目前再生混凝土结构的设计仍是一个挑战。本文从原生与再生混凝土结构构件统一设计的新需求出发，剖析了两者统一设计的必要性，并从强度取值、受压本构关系以及结构构件设计方法等方面进行了深入论证。分析发现，再生混凝土的强度变异系数总体上高于原生混凝土，再生混凝土的抗压强度及抗拉强度代表值的定义和取值方法与原生混凝土一致；原生与再生混凝土的单轴受压本构关系具有统一的数学表达形式，但与原生混凝土相比，再生混凝土弹性模量降低、脆性增加。最后，提出了再生混凝土构件安全可靠度调整系数，实现了再生与原生混凝土构件承载力设计公式的统一，并从概念设计和构造措施上，论证了考虑时变强度与钢筋锈蚀等影响的时变可靠度统一的可行性。本文的工作，丰富和发展了混凝土结构基本理论。

Unified description of sand behavior

Feng ZHANG, Bin YE, Guanlin YE

《结构与土木工程前沿（英文）》 2011年第5卷第2期页码 121-150 doi: 10.1007/s11709-011-0104-z

摘要： In this paper, the mechanical behavior of sand, was systematically described and modeled with a elastoplastic model proposed by Zhang et al. [ ]. Without losing the generality of the sand, a specific sand called as Toyoura sand, a typical clean sand found in Japan, has been discussed in detail. In the model, the results of conventional triaxial tests of the sand under different loading and drainage conditions were simulated with a fixed set of material parameters. The model only employs eight parameters among which five parameters are the same as those used in Cam-clay model. Once the parameters are determined with the conventional drained triaxial compression tests and undrained triaxial cyclic loading tests, then they are fixed to uniquely describe the overall mechanical behaviors of the Toyoura sand, without changing the values of the eight parameters irrespective of what kind of the loadings or the drainage conditions may be. The capability of the model is discussed in a theoretical way.

通讯式学习——统一的机器学习模式 Review

袁路遥, 朱松纯

《工程（英文）》 2023年第25卷第6期页码 77-100 doi: 10.1016/j.eng.2022.10.017

摘要：

In this article, we propose a communicative learning (CL) formalism that unifies existing machine learning paradigms, such as passive learning, active learning, algorithmic teaching, and so forth, and facilitates the development of new learning methods. Arising from human cooperative communication, this formalism poses learning as a communicative process and combines pedagogy with the burgeoning field of machine learning. The pedagogical insight facilitates the adoption of alternative information sources in machine learning besides randomly sampled data, such as intentional messages given by a helpful teacher. More specifically, in CL, a teacher and a student exchange information with each other collaboratively to transmit and acquire certain knowledge. Each agent has a mind, which includes the agent's knowledge, utility, and mental dynamics. To establish effective communication, each agent also needs an estimation of its partner's mind. We define expressive mental representations and learning formulation sufficient for such recursive modeling, which endows CL with human-comparable learning efficiency. We demonstrate the application of CL to several prototypical collaboration tasks and illustrate that this formalism allows learning protocols to go beyond Shannon's communication limit. Finally, we present our contribution to the foundations of learning by putting forth hierarchies in learning and defining the halting problem of learning.

基于自适应在线双词主题模型的应用程序评论新兴主题识别 Research Article

周芄1,王勇1,2,高翠芸3,杨非4

《信息与电子工程前沿（英文）》 2022年第23卷第5期页码 678-691 doi: 10.1631/FITEE.2100465

摘要：应用程序评论中的新兴主题突出了用户在一定时期内关注的主题（如软件漏洞）。准确、及时地识别新兴主题能帮助开发者更有效地更新应用程序。已有文献基于主题模型或聚类方法识别应用程序评论中的新兴主题。然而，由于评论文本长度较短，提供的信息有限，新兴主题识别准确率较低。为解决该问题，提出一种改进的新兴主题识别方法（IETI）。首先采用自然语言处理技术减少评论文本中的噪音数据，然后使用自适应在线双词主题模型识别评论中的新兴主题。最后利用新兴主题中相关的短语和句子解释新兴主题的含义。采用官方更新日志作为新兴主题的评估标准，选择6个常见的应用程序对IETI进行评估。实验结果表明，IETI在识别新兴主题方面优于传统方法，短语标签F1值增量为0.126，句子标签F1值增量为0.061。我们在Github（https://github.com/wanizhou/IETI）上发布了IETI的代码。

摘要：

知识是人类所创造的宝贵财富，但至今没有形成系统的知识理论。文章旨在提出和建立知识论的框架体系，包括它的基础和主体两部分。基础部分主要给出知识的概念、定义、表示、度量、推理和决策规则；主体部分的核心是阐明由信息提炼知识（知识生成）以及由知识形成智能（知识激活）的机理。知识论的建立将为信息论-知识论-智能论的统一理论奠定坚实的基础，促进人们在更高的水平上利用信息和知识，研究、设计和应用各种智能机器，推动经济和社会的发展。

Unified calculation method and its application in determining the uniaxial mechanical properties of concrete

Faxing DING, Xiaoyong YING, Linchao ZHOU, Zhiwu YU

《结构与土木工程前沿（英文）》 2011年第5卷第3期页码 381-393 doi: 10.1007/s11709-011-0118-6

摘要： This paper presents a unified calculation method and its application in determining the uniaxial mechanical properties of concrete with concrete strengths ranging from 10 to 140 MPa. By analyzing a large collection of test results of the uniaxial mechanical properties of normal-strength, high-strength and super high-strength concrete in China and performing a regression analysis, unified calculation formulas for the mechanical indexes of concrete are proposed that can be applied to various grades of concrete for determining the size coefficient, uniaxial compressive strength, uniaxial tensile strength, elastic modulus, and strain at peak uniaxial compression and tension. Optimized mathematical equations for the nonlinear stress-strain relationship of concrete, including the ascending and descending branches under uniaxial stress, are also established. The elastic modulus is almost constant throughout the elastic stage for the ascending branches of the stress-strain relationship for concrete. The proposed stress-strain relationship of concrete was applied to the nonlinear finite element analysis of both a steel-concrete composite beam and a concrete-filled steel tubular stub column. The analytical results are in good agreement with the experiment results, indicating that the proposed stress-strain relationship of concrete is applicable. The achievements presented in this paper can be used as references for the design and nonlinear finite element analysis of concrete structures.
