The Image Property in an EIT Information Transfer System

We focus on the study of the transferred image property in an electromagnetically induced transparency （EIT）system. In our experiment, a triple-peak image is effectively transferred trom a coupling beam to a signal beam based on the FIT effect. It is found that the transferred image intensity profile of the signal beam is the same as that of the coupling beam while not in phase. Furthermore, the propagation property of the transferred image is studied. Due to the narrowing effect, the transferred image keeps narrowing and maintains the shape well within a certain distance outside of the medium. Our experimental results are in excellent agreement with the theoretical analysis.

The Conflict and Balance Between Intellectual Property Rights and Public Freedom of Information in the“Anti-circumvention Clause”

There is a long-standing conflict between intellectual property rights and public freedom of information.The continuous development of the“anti-circumvention clause”has caused the conflict to intensify.As a basic human right,freedom of information is being gradually eroded by the expansion of intellectual property rights.The existing research mainly carries on the right balance from the negative protection path,but the positive protection path is more advantageous to realizing the public freedom of information and alleviates the conflict between the two kinds of rights.In practice,there are some problems in the application of the anti-circumvention clause,such as the legality of the aim,the division of the protected part,and the determination of the circumvention.This is mainly due to the lack of restrictions on technical measures,the failure to distinguish between“copyright protection”and“contact control”,and the offside and absence of administrative bodies in practice.We should protect public freedom of information by distinguishing the two measures of copyright protection and contact control and the two torts of access and use,increasing the restrictive conditions for the use of technical protection measures,and changing the functions of administrative supervision agencies.

A new measure for evaluating spatially related properties of traffic information credibility

With the wide applications of sensor network technology in traffic information acquisition systems,a new measure will be quite necessary to evaluate spatially related properties of traffic information credibility.The heterogeneity of spatial distribution of information credibility from sensor networks is analyzed and a new measure,information credibility function(ICF),is proposed to describe this heterogeneity.Three possible functional forms of sensor ICF and their corresponding expressions are presented.Then,two feasible operations of spatial superposition of sensor ICFs are discussed.Finally,a numerical example is introduced to show the calibration method of sensor ICF and obtain the spatially related properties of expressway in Beijing.The results show that the sensor ICF of expressway in Beijing possesses a negative exponent property.The traffic information is more abundant at or near the locations of sensor,while with the distance away from the sensor increasing,the traffic information credibility will be declined by an exponential trend.The new measure provides theoretical bases for the optimal locations of traffic sensor networks and the mechanism research of spatial distribution of traffic information credibility.

The topological indices were used to correlate with seven physical properties of the alkanes. Some empirical equations were obtained through regression. The regression and calculation results show a good agreement of the topological indices and the properties.

Informative Property of the Data Set in a Single-input Single-output (SISO) Closed-loop System with a Switching Controller

Closed-loop identification is important and necessary to various model-based advanced process control strategies, whose performance depends greatly on the informative property of the data set. Switching control is an important method in process control. Therefore, this paper studies the informative property of a data set in a single-input single-output (SISO) closed-loop system with a switching controller. It is proved that this data set is informative if the controller switches among at least two modes (i.e., feedback laws). Our result does not require any assumption on the way of switch and removes the constraints on the switching manner required in some classical literature. Finally, simulation case studies based on a continuous stirred-tank reactor (CSTR) process are given to validate the results.

Development of a Web-Based Geographic Information System for Mass Land Valuation: A Case Study of Westlands Constituency, Nairobi County

The development of a web-based Geographic Information System for mass property valuation was the main focus of this research. The developed web GIS allows effective dissemination, extraction and analysis of mass land valuation information over the Internet. It also allows for automation of the mass property valuation process by compiling a centralized mass valuation roll database. The Westlands Constituency, one of the administrative regions of the Nairobi City County was used as a case study. The research focused on automation of the mass property valuation roll by creating a centralized database that is accessible by all users on the web-based GIS portal. This was done by customizing and integrating a web-based GIS system based on open source QuantumGIS, GeoServer and PostgreSQL/PostGIS as a relational database. Leaflets APIs were used for the development of an interactive and friendly geographic user interface. The developed system enables users to view and interact with the spatial data. This improves the efficiency and effectiveness of the decision making process and data sharing for mass property valuation and optimal property taxation purposes.

Soil Resources Information System for Improving Productivity Using Geo-Informatics Technology

Soil surveying and mapping is an important operation, since it plays a key role in the knowledge about soil nutrients, properties and how it can be used for agriculture. This study was carried out in order to map soil chemical properties and macronutrients status in North, Center and South districts zones of Gujarat state. Geographic Information System (GIS) was used in this study to present the secondary data of the soil which were obtained from Anand Agriculture University (AAU), Gujarat. The major objective of this study was to analyze & visualize the secondary data of soil through IDW, spatial interpolation techniques for suitable mapping in a selected North, Central and South districts of Gujarat state. Various maps showing spatial distribution of micronutrients and chemical properties for North, Center and South districts zones of Gujarat state were prepared. These digital maps can be used in precision farming studies with the application of fertilizers and micro-nutrients as per the requirement and the recommendations. This approach is proposed as a method for the evaluation of sustainable soil management practices such as variable rate of fertilization. This study demonstrates the usefulness of geo-informatics technology in soil survey as well as applications of various micronutrients to specific areas based on recommendations.

DEAON： dynamically-evolving active overlay networks for scalable information retrieval

In this paper, we propose the dynamically-evolving active overlay network （DEAON）, which is an efficient, scalable yet simple protocol to facilitate applications of decentralized information retrieval in P2P networks. DEAON consists of three novel components ： a Desirable Topology Construction and Adaptation algorithm to guide the evolution of the overlay topology towards a small-world-like graph; a Semantic-based Neighbor Selection scheme to conduct an online neighbor ranking; a Topology-aware Intelligent Search mechanism to forward incoming queries to deliberately selected neighbors. We deploy and compare DEAON with other several existing distributed search techniques over static and dynamic environments. The results indicate that DEAON outperforms its competitors by achieving higher recall rate while using much less network resources, in both of the above environments.

Why The Constitution Should Protect Personal Credit Information?——An Approach of Right Argumentation

Protecting personal credit information through constitutional rights is not only essemtial for individuals to defend against infringements on their personal credit information rights and interests by public power in the social credit system,but also a requirement for unified legislation on social credit to explore the basis for constitutional norms.In the era of the credit economy,personal credit information has become a vital resource for realizing personal autonomy.Along with the increase in the state’s supervision and control of personal credit,the realization of the autonomous value in the interests related to personal credit information has also set more obligations for the state.Therefore,interests related to personal credit information should be regarded as a constitutional right.Because of its significant economic interest and value,the right to personal credit information should be classified as a constitutional property right.As a constitutional property right,the right to personal credit information can not only help protect people’s economic interests,but also achieve the goal of safeguarding their personality interests.

基于企业绩效视角的知识产权文本信息披露有效性研究

本文基于《知识产权相关信息披露规定》颁布这一外生冲击构建连续型DID模型,基于企业绩效视角考察知识产权文本信息披露的有效性。结果表明:在信息披露的信息效应和内损效应的影响下,《规定》颁布后企业披露的知识产权文本信息对企业绩效存在异质性影响。知识产权信息披露短期内并未给企业带来盈利能力的提升,而从长期看知识产权信息披露反映了市场对公司的良好预期。债权融资水平的降低是知识产权信息披露降低企业短期绩效的潜在机制,权益资本成本的降低是知识产权信息披露提升企业长期绩效的潜在机制。按信息类型分类分析发现,优势信息和内容信息与短期绩效的负向关系更显著,内容信息、优势信息和风险信息对长期绩效的正向影响程度依次减弱。截面分组发现,成长期和衰退期企业知识产权信息披露与短期绩效的负向关系更显著,成长期和成熟期企业知识产权信息披露与长期绩效的正向关系更显著。研究不仅证明了知识产权信息披露对企业绩效存在的差异性影响,也对政府逐步完善知识产权信息披露政策,企业更好地开展知识产权信息披露的实践活动均具有借鉴意义。

基于中外文献关键词网络分析的知识产权信息服务研究

知识产权信息服务是加强知识产权强国建设,支撑国家参与全球化竞争的重要途径。利用文献可视化工具,通过高频关键词共现、聚类、突现分析,对2013-2022年知识产权信息服务领域发表的中外文相关文献进行对比,探索近10年该领域研究现状、热点和发展趋势的差异。研究发现,专利分析仍然是知识产权信息服务的核心内容;国内图书馆尤其是高校图书馆成为知识产权信息服务网点之一;中外文文献都十分关注知识产权信息服务平台建设、公共服务体系建设。相比之下,中文文献重点针对用户需求提升服务能力、服务效果等,对知识产权信息服务的商业模式探索较少,对版权、商标关注不够。从近10年的研究主题演进阶段中可以看出,中文文献中知识产权信息服务领域研究起步于科技查新,在平台建设中不断完善,初步构建服务体系。而外文文献则关注新技术在知识产权信息服务中的应用,重视专利分析、版权以及信息安全等相关问题。

个人信息数据财产化及其确权授权模式构建

个人信息数据确权授权若适用传统人格标识财产化模式,要么导致基础权益错配,要么造成流转效用受阻。通过对财产价值溯源可以发现,个人信息存在原始数据、数据集合、衍生数据三种形态。原始数据非对人“有用的财物”,不构成财产权客体,但因其是个人信息的比特化表达,所以在数字空间中,个人信息权需以其为行权媒介;而数据集合与衍生数据则是数据财产权客体。数据三形态厘清了个人信息权、个人信息数据使用权及数据财产权的差序格局。个人信息数据的商业利用以个人信息权为基础,基于人格自决形成以信息主体同意为路径的许可机制。同意为准法律行为,许可生成低自由度的个人信息数据使用权,该权区别于处理者的数据财产权,需引入告知允诺之债和法定信义义务,以保护信息主体在同意许可中的信赖。
