A New Model for Network Security Situation Assessment of the Industrial Internet

To address the problem of network security situation assessment in the Industrial Internet,this paper adopts the evidential reasoning(ER)algorithm and belief rule base(BRB)method to establish an assessment model.First,this paper analyzes the influencing factors of the Industrial Internet and selects evaluation indicators that contain not only quantitative data but also qualitative knowledge.Second,the evaluation indicators are fused with expert knowledge and the ER algorithm.According to the fusion results,a network security situation assessment model of the Industrial Internet based on the ER and BRB method is established,and the projection covariance matrix adaptive evolution strategy(P-CMA-ES)is used to optimize the model parameters.This method can not only utilize semiquantitative information effectively but also use more uncertain information and prevent the problem of combinatorial explosion.Moreover,it solves the problem of the uncertainty of expert knowledge and overcomes the problem of low modeling accuracy caused by insufficient data.Finally,a network security situation assessment case of the Industrial Internet is analyzed to verify the effectiveness and superiority of the method.The research results showthat this method has strong applicability to the network security situation assessment of complex Industrial Internet systems.It can accurately reflect the actual network security situation of Industrial Internet systems and provide safe and reliable suggestions for network administrators to take timely countermeasures,thereby improving the risk monitoring and emergency response capabilities of the Industrial Internet.

A Study on the Funding Management of Agricultural Scientific Research Project in the New Situation

On the Current Situation of Basic - level Administrative Law Enforcement in China

With the development of economy and society, our country is on the road of rule by law, the legal system is progressing constantly. At the same time, we should also see that the administration according to law is not perfect, and its shortcomings exist in different degree and need to be further improved. Based on the analysis of the status quo of grass-roots administrative law enforcement in China, this paper tries to put forward corresponding countermeasures, so as to promote the work of law-based administration for the corresponding study.

A class of fully third-order accurate projection methods for solving the incompressible Navier-Stokes equations

In this paper, a fully third-order accurate projection method for solving the incompressible Navier-Stokes equations is proposed. To construct the scheme, a continuous projection procedure is firstly presented. We then derive a sufficient condition for the continuous projection equations to be temporally third-order accurate approximations of the original Navier-Stokes equations by means of the localtruncation-error-analysis technique. The continuous projection equations are discretized temporally and spatially to third-order accuracy on the staggered grids, resulting in a fully third-order discrete projection scheme. The possibility to design higher-order projection methods is thus demonstrated in the present paper. A heuristic stability analysis is performed on this projection method showing the probability of its being stable. The stability of the present scheme is further verified through numerical tests. The third-order accuracy of the present projection method is validated by several numerical test cases.

How Project-Based Organizations Cultivate Learning in Projects: A Social-Constructivist Perspective

A growing number of studies are now emphasizing the critical importance of learning and knowledge accumulation for firm-level competitiveness. Despite the growing awareness, relatively fewer project-based firms have institutionalized mechanisms to systematically capture new project knowledge and re-use it to improve the execution of subsequent projects. The peculiarity of projects presents unique challenges that make the cognitive approach to learning difficult to implement. As such, researchers are recommending the social constructivist perspective of learning as the most viable strategy for cultivating learning within and across projects. However, scant work has been undertaken from this sociological perspective to analyze how temporary organizations manage knowledge arising from and relating to projects. From this standpoint, the aim of this paper is to discuss the learning mechanisms of construction firms. The study adopted a quantitative strategy by employing a questionnaire survey into the learning practices of construction projects in Ghana. Drawing on preliminary findings from the literature, the study proposes a model for cultivating learning within projects from the social constructivist viewpoint. In the model, project management practitioners can purposefully nurture or structure a project learning activity through four mechanisms viz.: institutionalization, externalization, socialization and internalization. The proposed model is subsequently validated in an empirical study into the learning practices during the implementation of construction projects in Ghana. Based on the empirical results, it seems that knowledge sharing and transfers through the four aforementioned learning mechanisms proposed by the model are highly regarded within project management practice in Ghana.

Comment on the Recent Start of a New “IUPAC-Project”

The opening of a new IUPAC-project is highly appreciated. In the year 2009, the IUPAC had published an article “Discovery of the element with atomic number 112 (IUPAC Technical Report)” [1]* which contains a section on the work of the Marinov collaboration. It appears that this section is not always in agreement with conventional standards for scientific publications. This present comment focuses on these formal questions.

Towards delivery of situational information in distributed environments

In the distributed environment,robots should be able to provide users with adaptive services automatically according to the situational information changing dynamically which is obtained from both users and their environments.The workflow depends on situational information obtained from physical environments and provides context-aware services automatically based on the information retrieved.And the workflow in the business processes and the distributed computing environments have supported the automation of services by connecting tasks.The workflow needs to specify ubiquitous situational information as state-transition constraints.However,the delivery and use of sensor data in the workflow is a difficult problem for the robot system.In order to bridge the gap between applications and low-level constructs and to acquire raw situational information for the execution of the context-aware workflow in the robot systems,this paper presents an approach which can achieve the sensor data transmission between a sensing server and a robot system easily.

认知视域下语言运用三级析解

语言有多重属性。在语言运用中,经济性和认知性发挥着重要作用,其中,认知性的作用更为基础。据此,我们提出认知原理统领下的语言运用三级表达—解读理论框架。在一级运用阶段,语言解读是运用“整一性投射”策略解决读懂的问题;表达则是要利用这一策略使语言更为简省。其中,运用“整一性投射”就是要利用百科知识,也就是语言主体的认知能力。二、三级运用是在读懂的基础上进一步运用情境关联的策略,其中的三级运用是专门针对非字面义表达的。情境关联的实现更能体现认知活动的基本原理:认知主体同环境的相互作用。通过情境关联,主体的“情”同“境(景)”里的物关联起来,主体对所表达的事物进行联想、想象,作出主观的认知加工,实现“情以物迁,辞以情发”。
