Computational intelligence interception guidance law using online off-policy integral reinforcement learning

Missile interception problem can be regarded as a two-person zero-sum differential games problem,which depends on the solution of Hamilton-Jacobi-Isaacs(HJI)equa-tion.It has been proved impossible to obtain a closed-form solu-tion due to the nonlinearity of HJI equation,and many iterative algorithms are proposed to solve the HJI equation.Simultane-ous policy updating algorithm(SPUA)is an effective algorithm for solving HJI equation,but it is an on-policy integral reinforce-ment learning(IRL).For online implementation of SPUA,the dis-turbance signals need to be adjustable,which is unrealistic.In this paper,an off-policy IRL algorithm based on SPUA is pro-posed without making use of any knowledge of the systems dynamics.Then,a neural-network based online adaptive critic implementation scheme of the off-policy IRL algorithm is pre-sented.Based on the online off-policy IRL method,a computa-tional intelligence interception guidance(CIIG)law is developed for intercepting high-maneuvering target.As a model-free method,intercepting targets can be achieved through measur-ing system data online.The effectiveness of the CIIG is verified through two missile and target engagement scenarios.

Digital Twin Technology of Human-Machine Integration in Cross-Belt Sorting System

The Chinese express delivery industry processes nearly 110 billion items in 2022,averaging an annual growth rate of 200%.Among the various types of sorting systems used for handling express items,cross-belt sorting systems stand out as the most crucial.However,despite their high degree of automation,the workload for operators has intensified owing to the surging volume of express items.In the era of Industry 5.0,it is imperative to adopt new technologies that not only enhance worker welfare but also improve the efficiency of cross-belt systems.Striking a balance between efficiency in handling express items and operator well-being is challenging.Digital twin technology offers a promising solution in this respect.A realization method of a human-machine integrated digital twin is proposed in this study,enabling the interaction of biological human bodies,virtual human bodies,virtual equipment,and logistics equipment in a closed loop,thus setting an operating framework.Key technologies in the proposed framework include a collection of heterogeneous data from multiple sources,construction of the relationship between operator fatigue and operation efficiency based on physiological measurements,virtual model construction,and an online optimization module based on real-time simulation.The feasibility of the proposed method was verified in an express distribution center.

Research and Practice of the “Independence + Integration” Moral and Self-cultivation Teaching Method for Online Specialized Courses

In the context of the COVID-19 outbreak,online teaching has spread rapidly.However,the existing research on moral and self-cultivation teaching methods for online courses remains inadequate.This paper proposes an“independence+integration”moral and self-cultivation teaching method for online courses.The method divides the targets of moral and self-cultivation teaching into independent and integrated ones,and fits them both explicitly and implicitly into the online teaching of specialized courses in higher education.When this method was employed to teach engineering mechanics to industrial design students at a college in China,it effectively increased the students’acceptance of online courses as well as their understanding of moral and self-cultivation knowledge and the course itself,and improved the quality of online teaching.The method provides a new way of thinking about online moral and self-cultivation teaching.

Teaching Model Integrating Online and Offline in Real Time ——An Exploration of New Teaching Mode for Regular Epidemic Prevention and Control

During epidemic,students in medium-risk or high-risk areas are unable to return to school on time.In response to this new challenge,there is an urgent need to create a new teaching mode to offer on-line courses to those absent from the offline classes,and we propose a model integrating online and offline teaching.It is based on“dual-camera”method,which allows off-campus students to virtually build up a physical classroom scenario on campus through computers and mobile phones.Using this model,students can participate in class remotely.In order to enhance the engagement of off-campus online students,emphasis is placed on interactive teaching.Teachers are required to design their teaching in advance and to work in collaboration with multiple departments,then using information technology and suitable teaching methods to enable students to participate in physical classroom teaching.This model has been tested in practice and has been successful in meeting the challenges.Finally,4 areas for improvement and refinement are identified.

A Comparative and Integrated Study of English Composition Online Automatic Scoring (OAS) and Teacher Scoring (TS)

The objective of this paper is to explore the reliability of Online Automatic Scoring(OAS)through the comparison of OAS and Teacher Scoring(TS),and further demonstrate the feasibility of the integration of the two scoring methods.The Pearson correlation statistics of the two scoring results of 115 compositions are processed with SPSS analysis software,indicating that the correlation between the two reaches 0.83,which means that OAS is relatively reliable in dealing with students’compositions.After the second stage of the TS experiment,the questionnaire results show that students generally recognize the OAS and have a clear understanding of the advantages and disadvantages of the two scoring methods.Combined with the students’interview,the conclusion is that the OAS is reliable and the integration of the two scoring methods will have a better effect.

Integrated separation-electrochemical detection device based on wood column for online identification of enantiomer

Chiral chemicals have attracted significant interest in the pharmaceutical industry,yet the separation methods to get pure enantiomers from racemic mixture are still challenging.To date,the separation of enantiomers still mainly depends on chromatography using high-cost chiral stationary phases.Herein,wood channels were used as the handheld integrated device,and enantiomer separation was simultaneously detected using an electrochemical detector.In this method,a chiral UIO-66(L-UIO-66)modified enantiomer separation zone and carbonized wood based online detection zone are integrated along a single wood column.Based on the in situ separation results from the chronoamperometry data,the wood device shows excellent separation ability for a wide range of electrochemically active enantiomers,including 3,4-dihydroxyphenylalanine,amino acids,ascorbic acid,carnitine,and penicillamine with high chirality purity.The unbiased molecular dynamic simulations indicate that the excellent chiral recognition and separation are attributed to the different barriers from the bound states to the dissociated state of the enantiomers in the homochiral microenvironment of the framework.This integrated enantiomer separation-electrochemical detection device provides a novel,easy,and low-cost platform for the separation of pure enantiomer from racemic mixture.

Exploration and Reflection on College Online English Teaching in Henan Police College

Under the background of the Internet Plus,the research on the online and offline integrated teaching mode is particularly important.Therefore,based on the teaching of Henan Police College and taking the college English course as an example,this paper investigates and analyzes the online teaching situation.The results show that there are significant differences between gender and grade in students’online English learning;the biggest difficulty for students in online English learning is the lack of learning materials like textbooks and the simultaneous use of multiple equipment in class;the biggest problem in the ideological and political integration of English course is that the way of ideological and political integration in English class lacks of variety.Through this research,it is hoped to help teachers in HNP college improve the online teaching mode,improve the online teaching quality,and promote the normalization of online and offline teaching mode.
