Stochastic Model for Multiple Classes and Subclasses Simple Documents Processing

The issue of document management has been raised for a long time, especially with the appearance of office automation in the 1980s, which led to dematerialization and Electronic Document Management (EDM). In the same period, workflow management has experienced significant development, but has become more focused on the industry. However, it seems to us that document workflows have not had the same interest for the scientific community. But nowadays, the emergence and supremacy of the Internet in electronic exchanges are leading to a massive dematerialization of documents;which requires a conceptual reconsideration of the organizational framework for the processing of said documents in both public and private administrations. This problem seems open to us and deserves the interest of the scientific community. Indeed, EDM has mainly focused on the storage (referencing) and circulation of documents (traceability). It paid little attention to the overall behavior of the system in processing documents. The purpose of our researches is to model document processing systems. In the previous works, we proposed a general model and its specialization in the case of small documents (any document processed by a single person at a time during its processing life cycle), which represent 70% of documents processed by administrations, according to our study. In this contribution, we extend the model for processing small documents to the case where they are managed in a system comprising document classes organized in subclasses;which is the case for most administrations. We have thus observed that this model is a Markovian ML×K/ML×K/1 queues network. We have analyzed the constraints of this model and deduced certain characteristics and metrics. In fine, the ultimate objective of our work is to design a document workflow management system, integrating a component of global behavior prediction.

软件中代码注释质量问题研究综述

代码注释作为辅助软件开发群体协作的关键机制,被开发者所广泛使用以提升开发效率.然而,由于代码注释并不直接影响软件运行,使其常被开发者忽视,导致出现代码注释质量问题,进而影响开发效率.代码注释中存在的质量问题会影响开发者理解相关代码,甚至可能产生误解从而引入代码缺陷,因此这一问题受到研究者的广泛关注.采用系统文献调研,对近年来国内外学者在代码注释质量问题上的研究工作进行系统的分析.从代码注释质量的评价维度、度量指标以及提升策略这3个方面总结研究现状,并提出当前研究所存在的不足、挑战及建议.

“党的领导”如何嵌入政府过程?——以党政联合发文为分析框架

“党的领导”既是一种政治原则,也是一整套实现国家治理现代化的体制机制。在国家治理的场景中,文件作为科层内部联系的载体贯穿政府活动的始终,而党政联合发文又是党政治理结构高效运行的重要依托和实现党领导政府的具体机制,兼具党的文件和政府的政策性文件双重属性,使其成为观察“党的领导”嵌入政府过程的直观视角。党政联合发文机制的运行过程涵盖动议、起草、修改、会签和公布五个前后衔接的环节。基于此提炼分析框架,可以将“党的领导”嵌入政府过程的基本逻辑抽象为“议题设定—规则创制—效力生成”,分别代表着任务嵌入、内容嵌入和权威嵌入三重维度。借助对这一机制的阐释,可能有助于从理论层面回应政党是以何种方式与国家政权发生关联进而实现有效治国理政这一问题。可以发现,“党的领导”不仅是一种政治原则,还是一整套相互衔接的体制机制。其中,党政联合发文在贯彻“党的领导”上发挥了重要作用。

A Novel CAPP System Based on SML for Variant Design of Process Planning

The production model of“multi-specification and low-quantity”is becoming the main trend of manufacturing industry.As a key activity in the manufacturing chain,traditional computer aided process planning(CAPP)system fails to adapt to the production model of customization.Therefore,a novel method for variant design of process planning was proposed to develop CAPP system based on Tabular Layouts of Article Characteristics(Sach-Merk Leisten in German and SML for short). With the support of standard database of master process planning documents which are developed by parameterization technique, and instance process planning for special product(instance product)can be generated automatically by the sub-system of variant de- sign of process planning.Finally,a CAPP system was developed for process design of rotor of steam turbine to validate the feasibil- ity and applicability of the method.

Measuring Qualities of XML Schema Documents

The Extensible Markup Language (XML) is becoming a de-facto standard for exchanging information among the web applications. Efficient implementation of web application needs to be efficient implementation of XML and XML schema document. The quality of XML document has great impact on the design quality of its schema document. Therefore, the design of XML schema document plays an important role in web engineering process and needs to have many schema qualities: functionality, extensibility, reusability, understandability, maintainability and so on. Three schema metrics: Reusable Quality metric (RQ), Extensible Quality metric (EQ) and Understandable Quality metric (UQ) are proposed to measure the Reusable, Extensible and Understandable of XML schema documents in web engineering process respectively. The base attributes are selected according to XML Quality Assurance Design Guidelines. These metrics are formulated based on Binary Entropy Function and Rank Order Centroid method. To check the validity of the proposed metrics empirically and analytically, the self-organizing feature map (SOM) and Weyuker’s 9 properties are used.

Petro-chemical wastewater treatment by biological process

In order to study the feasibility of treating petro chemical wastewater by the combination of anaerobic and aerobic biological process, a research of treating wastewater in UASB reactor and aeration basin has been conducted. The test results shows that under moderate temperature, with 5\^2 kgCOD/(m\+3·d) volumetric load of COD Cr in the UASB reactor and 24h of HRT, 85% removal rate of BOD 5 and 83% of COD \{Cr\} and 1\^34 m\+3/(m\+3·d) volumetric gas production rate can be obtained respectively. The aerobic bio degradability can be increased by 20%—30% after the petro chemical wastewater has been treated by anaerobic process. As Ns=0\^45 kgCOD/(kgMLSS·d), HRT=4h in the aeration tank, 94% removal rate of BOD 5, 93% of COD \{Cr\}, 98\^8% total removal rate of COD \{Cr\} and 99% removal rate of BOD 5 can be reached.

岸田内阁防卫政策调整的决策过程及其特点——以反击能力的推进为例

岸田内阁对防卫三文书的修订是战后日本防卫政策的一次重大调整,而拥有反击能力则是此次调整的核心。由于岸田文雄自身的政治基盘比较脆弱,内阁本身较为弱势,岸田不得不依靠自民党和美国的力量协助决策。在他的推动下,自民党在拥有反击能力的决策过程中发挥了关键作用,岸田内阁防卫政策的决策过程体现了明显的“政高党高”特征。自民党主导了围绕反击能力具体内容的讨论,并和防卫省合作,明确了反击能力所需的装备技术。然而,逐渐掌握话语权的自民党保守势力却在反击能力所需的预算及其财源问题上与岸田发生矛盾冲突,反而威胁到了首相的决策权。另一方面,美国因素同样在本次防卫政策的决策过程中起到了助推和加速作用,未来也可能持续影响日本反击能力的落实进程。

Research on Explicit and Tacit Knowledge Interaction in Software Process Improvement Project

This research develops a knowledge model for Software Process Improvement (SPI) project based on knowledge creation theory and its twenty-four measurement items, and proposes two hypothesizes about the interaction of explicit knowledge and tacit knowledge in SPI. Eleven factors are extracted through statistical analysis. Three knowledge-creation practices for capturing tacit knowledge contribute greatly to SPI, which are communication among members, crossover collaboration in practical work and pair programming. Two knowledge-creation practices for capturing explicit knowledge have significant positive impact on SPI, which are integrating project document and on-the-job training. Ultimately, suggestions for improvement are put forward, that is, encouraging communication among staff and integrating documents in real time, and future research is also illustrated.
