Synthesis-free directional modulation for retrodirective frequency diverse array

引用

Science China(Information Sciences) 2020年第10期63卷 152-173页

作者： sheng ke Jianping AN Shuai WANG School of Information and Electronics Beijing Institute of Technology

Combination of directional modulation(DM) and frequency diverse array(FDA) provides a novel opportunity for enabling physical layer security because of the enhanced ability of distance ***, in the existing studies, the time-varying nature of the FDA pattern is usually ignored. In this paper, a modified model of FDA-DM is proposed, in which the ignored time factor in the previous studies is taken into consideration for providing a new and more accurate perspective on evaluating the security of FDA-DM. Furthermore, we reveal that FDA-DM can achieve angle-dependent and directional-time-coupleddependent security. After that, based on the retrodirective FDA(RFDA) with a new structure, a novel synthesis-free FDA-DM scheme is proposed for both overcoming the limitations of the FDA-DM scheme and allowing self-tracking the position of the pilot signal without any prior knowledge. Meanwhile, a new set of nonlinear frequency offsets, defined as rearranged linear frequency offsets(RLFOs), is also proposed for both combining the advantages of the linear/nonlinear frequency offsets and bringing conveniences to practical implementation. In addition, the closed-form expression of the average signal-to-artificial-noise-ratio(SANR)is given out for evaluating the security performance of the proposed scheme. Finally, numerical results are presented to verify both the accuracy of the proposed theoretical analysis and the superiority of the RFDADM scheme.

Towards zero-defect manufacturing(ZDM)——a data mining approach

引用

Advances in Manufacturing 2013年第1期1卷 62-74页

作者： ke-sheng Wang Knowledge Discovery Laboratory Department of Production and Quality EngineeringNorwegian University of Science and Technology

The quality of a product is dependent on both facilities/equipment and manufacturing processes. Any error or disorder in facilities and processes can cause a catastrophic failure. To avoid such failures, a zero- defect manufacturing （ZDM） system is necessary in order to increase the reliability and safety of manufacturing systems and reach zero-defect quality of products. One of the major challenges for ZDM is the analysis of massive raw datasets. This type of analysis needs an automated and self-orga- nized decision making system. Data mining （DM） is an effective methodology for discovering interesting knowl- edge within a huge datasets. It plays an important role in developing a ZDM system. The paper presents a general framework of ZDM and explains how to apply DM approaches to manufacture the products with zero-defect. This paper also discusses 3 ongoing projects demonstrating the practice of using DM approaches for reaching the goal of ZDM.

The capability automated warehouse in of a company to implement an an optimized way might be nowadays a crucial leverage in order to gain competitive advantage to satisfy the demand. The order picking is a warehouse function that needs to deal with the retrieval of articles from their storage locations. Merging several single customer orders into one, a picking order can increase efficiency of warehouse operations. The aim of this paper is to define throughout the use of ad-hoc genetic algorithm （GA） how better a warehouse can be set up. The paper deals with order batching, which has a major effect on efficiency of warehouse operations to avoid wastes of resources in terms of processes and to control possibility of unexpected costs in advance.

Intelligent predictive maintenance for fault diagnosis and prognosis in machine centers： Industry 4.0 scenario

引用

Advances in Manufacturing 2017年第4期5卷 377-387页

作者： Zhe Li Yi Wang ke-sheng Wang Department of Mechanical and Industrial Engineering Norwegian University of Science and TechnologyTrondheim Norway School of Business Plymouth University Plymouth UK

Fault diagnosis and prognosis in mechanical systems have been researched and developed in the last few decades at a very rapid rate. However, owing to the high complexity of machine centers, research on improving the accuracy and reliability of fault diagnosis and prognosis via data mining remains a prominent issue in this field. This study investigates fault diagnosis and prognosis in machine centers based on data mining approaches to formulate a systematic approach and obtain knowledge for predictive maintenance in Industry 4.0 era. We introduce a system framework based on Industry 4.0 concepts, which includes the process of fault analysis and treatment for predictive maintenance in machine centers. The framework includes five modules： sensor selection and data acquisition module, data preprocessing module, data mining module, decision support module, and maintenance implementation module. Furthermore, a case study is presented to illustrate the application of the data mining methods for fault diagnosis and prognosis in machine centers as an Industry 4.0 scenario.

SUSTAINABLE RURAL LIVELIHOOD AND ECOLOGICAL SHELTER CONSTRUCTION IN UPPER REACHES OF CHANGJIANG RIVER——Case Study of Zhaotong of Yunnan Province

Sustainable livelihood theory provides a comprehensive framework for understanding the interactions between livelihoods of peasant households and regional environment change in low-income areas. Based on field survey and 946 questionnaires from peasant household conducted in the case study area of Zhaotong, Yunnan Province, the paper has analyzed the basic characteristics of the rural livelihoods, including the asset base status, the income-generating activities, the energy consumption pattern, and the fertility behavior, in the upper reaches of the Changjiang (Yangtze) River. The micro-level findings show the conflicts among extensive agricultural development models, rural energy consumption structures heavily relying on biomass and the environment protection. The conversion of cropland to forest and grass program(CCFGP) has exerted an important influence on the livelihoods of the peasant households, but its design has given little considerations to their long-term livelihood sources, which will affect its sustainability to a great extent. From the perspective of sustainable livelihoods framework, the objectives that must be addressed in the ecological shelter construction in the upper reaches of the Changjiang River should include, first, facilitating access of peasant households to credit, technology and public services, second, encouraging the peasant households to adopt agricultural technology with environmental benefits and strengthen resources-conserving investments, and third, paying close attention to the rural energy problems and the long-term livelihood sources of the households with CCFGP. Given the weak asset base and difficulties of livelihood strategies shift, ecological shelter construction in the upper reaches of the Changjiang River will take a long time.
