In order to enlarge the field of application, reduce the cost of software rejuvenation and improve software availability and reliability,the adaptive software rejuvenation with fine rejuvenation granularity of object-oriented software system would be put forward. Based on the characteristics of the component and coupling relation between the components of the system, this paper determines the finest rejuvenation granularity, analyzes the degree of the coupling relation,sets down a method to calculate the restart dependence and its degree of the components,so that determines the restart reachable set of each component and gets the restart gather of the components at every granularity,and finally sets down and models the adaptive nested software rejuvenation policy. So executing intelligent software rejuvenation at fine rejuvenation granularity in the object-oriented software system can be supported.

Frontiers of Information Technology & Electronic Engineering 2021, Volume 22, Issue 3,   Pages 287-436 doi: 10.1631/FITEE.1900649

Abstract: With technological advancements, weapon system development has become increasingly complex and costly. Using modeling and simulation (M&S) technology in the conceptual design stage is effective in reducing the development time and cost of weapons. One way to reduce the complexity and trial-and-error associated with weapon development using M&S technology is to develop s to review the functions assigned to new weapons. Although the M&S technology is applicable, it is difficult to analyze how effectively the weapons are functioning, because of the dynamic features inherent in modeling, which considers interrelations among different weapon entities. To support review of weapon functions including these characteristics, this study develops a method to model the interactions between weapons in the . This method includes the following three steps: (1) construct virtual models by converting the weapons and the weapon functions into their corresponding components; (2) generate the combat process from the , which is derived from the interrelations among weapons under consideration using reasoning rules; (3) develop a process-based model that describes weapon functions by combining the combat process with virtual models. Then, a PBM system based on this method is implemented. The case study executed on this system shows that it is useful in deriving process-based models from various s, analyzing weapon functions using the derived models, and reducing weapon development issues in the conceptual design stage.

Rhizosphere immunity: targeting the underground for sustainable plant health management

Zhong WEI, Ville-Petri FRIMAN, Thomas POMMIER, Stefan GEISEN, Alexandre JOUSSET, Qirong SHEN

Frontiers of Agricultural Science and Engineering 2020, Volume 7, Issue 3,   Pages 317-328 doi: 10.15302/J-FASE-2020346

Abstract:

Managing plant health is a great challenge for modern food production and is further complicated by the lack of common ground between the many disciplines involved in disease control. Here we present the concept of rhizosphere immunity, in which plant health is considered as an ecosystem level property emerging from networks of interactions between plants, microbiota and the surrounding soil matrix. These interactions can potentially extend the innate plant immune system to a point where the rhizosphere immunity can fulfil all four core functions of a full immune system: pathogen prevention, recognition, response and homeostasis. We suggest that considering plant health from a meta-organism perspective will help in developing multidisciplinary pathogen management strategies that focus on steering the whole plant-microbe-soil networks instead of individual components. This might be achieved by bringing together the latest discoveries in phytopathology, microbiome research, soil science and agronomy to pave the way toward more sustainable and productive agriculture.

Obtain the optimum of logistics delivery network with annealing algorithm

Duan Jingmin,Chang Yuejun,Li Zanxiang,Cui Jianming

Strategic Study of CAE 2012, Volume 14, Issue 7,   Pages 109-112

Abstract:

Simulated annealing algorithm is a heuristic algorithm, proposed one approximation algorithm of solving optimization combinatorial problems inspired by objects in the annealing process by heating crunch. The algorithm is superior to the traditional greedy algorithm,which avoids falling into local optimum and reaches global optimum. There are often some problems to find the shortest path, etc., in the logistics and we distribution network, and we need optimization for logistics and distribution path in order to achieve the shortest, best, most economical, and so on. The paper uses an example of simulated annealing algorithm to verify it, and the method is proved to be feasible.

Message delay time distribution analysis for controller area network under errors Research Papers

Lei-ming ZHANG, Yi-chao SUN, Yong LEI

Frontiers of Information Technology & Electronic Engineering 2019, Volume 20, Issue 6,   Pages 760-772 doi: 10.1631/FITEE.1700815

Abstract:

Controller area network (CAN) is a widely used fieldbus protocol in various industrial applications. To understand the network behavior under errors for the optimal design of networked control systems, the message response time of the CAN network needs to be analyzed. In this study, a novel delay time distribution analysis method for the response messages is proposed when considering errors. In this method the complex message queues are decomposed into typical message patterns and cases. First, a stochastic fault model is developed, and the probability factor is defined to calculate the error distribution. Then the message delay time distribution for the single slave node configuration is analyzed based on the error distribution. Next, based on the delay time distribution analysis of typical patterns and cases, an analysis framework of message delay time distribution for the master/slave configuration is developed. The testbed is constructed and case studies are conducted to demonstrate the proposed methodology under different network configurations. Experimental results show that the delay time distributions calculated by the proposed method agree well with the actual observations.

Ubiquitous Energy Internet—New Energy Internet Coupling with Information and Energy

Gan Zhongxue,Zhu Xiaojun,Wang Cheng and Chen Yue

Strategic Study of CAE 2015, Volume 17, Issue 9,   Pages 98-104

Abstract:

With the world energy crisis and environmental protection issues, countries around the world are actively engaged in exploring the new way of the future energy development. In recent years, Jeremy Rifkin, the famous American economist, proposed the idea of the third industrial revolution and the energy internet which caused widespread concern. Following this trend, countries put forward their own development strategies of industrial technology which are driven by internet respectively, such as: the third industrial revolution and industrial Internet of American, industry 4.0 of Germany, smart grid and “Internet + energy” of China. Based on energy efficiency theory in the system, the ubiquitous energy Internet has a stereoscopic structure which consists of three levels: information network, energy network and physical network. By using the optimization control based on the coupling between information and energy to adjust measures to local conditions and fully exploit the multiple grade energy, the ubiquitous energy Internet can give the solution to the integration stability of the renewable energy and the dynamic matching between demand and supply, and become a representative internet of the new energy.
