Classroom teaching behavior coding has received widespread attention from classroom analysis researchers in China in recent years. However, in the context of big data, how to effectively analyze the data of classroom teaching behavior is an important problem that urgently needs to be solved. In combination with bibliometric means, 422 articles published from 2004 to 2022 are encoded and analyzed. The analysis found that with the vigorous development of classroom teaching behavior coding, a new trend of interdisciplinary integration and the applied topic fields are gradually expanding from micro to macro. © 2022 IET conference Proceedings.

The traditional blockchain has the shortcoming that a single-chain can only deal with one or a few specific data types. The research question of how to make blockchain be able to deal with various data types has not been well studied. In this paper, we propose a single-chain based extension model of blockchain for fintech (SEBF). In the financial environment, we design a four-layer architecture for this model. By employing the external trusted oracle group and a financial regulator agency, a variety types of data can be effectively stored in the blockchain, such that the data type extension based on a single-chain is realized. The experimental results indicate that the proposed model can improve the efficiency of simplified payment verification. © 2020 Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.

Checking compliance to coding standards for x86 executables

COTS component evaluation is one of the most important steps in component-based development. Enforcing the coding standard within the coding phase is one important aspect for the quality of safety-critical software. This paper addresses the problem of carrying out COTS component evaluation of its compliance to the coding standard in case when only the executables with neither source code nor debugging information are available. The static binary analysis techniques are employed to discuss the feasibilities and possible approaches of checking compliance to coding standard rules for x86 executables. This work is our known first attempt to address this problem. About 27% of the MISRA-C 2004 rules can be checked or partially checked for x86 executables. Experiments are presented to conclude that for the rules related to unstructuredness and pointer cast, violations found from executables can be a reasonable approximation of the extent of compliance to the coding standard of the corresponding source code. © 2010 IEEE.

A real-coding jumping gene genetic algorithm (RJGGA) for multiobjective optimization

This paper presents a real jumping gene genetic algorithm (RJGGA) as an enhancement of the jumping gene genetic algorithm (JGGA) [T.M. Chan, K.F. Man, K.S. Tang, S. Kwong, A jumping gene algorithm for multiobjective resource management in wideband CDMA systems, The Computer Journal 48 (6) (2005) 749-768;T.M. Chan, K.F. Man, K.S. Tang, S. Kwong, Multiobjective optimization of radio-to-fiber repeater placement using a jumping gene algorithm, in: Proceedings of the IEEE international conference on Industrial technology (ICIT 2005), Hong Kong, 2005, pp. 291-296;K.F. Man, T.M. Chan, K.S. Tang, S. Kwong, Jumping-genes in evolutionary computing, in: Proceedings of the IEEE IECON'2004, Busan, 2004, pp, 1268-1272]. JGGA is a relatively new multiobjective evolutionary algorithm (MOEA) that imitates a jumping gene phenomenon discovered by Nobel Laureate McClintock during her work on the corn plants. The main feature of JGGA is that it only has a simple operation in which a transposition of gene(s) is induced within the same or another chromosome in the genetic algorithm (GA) framework. In its initial formulation, the search space solutions are binary-coded and it inherits the customary problems of conventional binary-coded GA (BCGA). This issue motivated us to remodel the JGGA into RJGGA. The performance of RJGGA has been compared to other MOEAs using some carefully chosen benchmark test functions. It has been observed that RJGGA is able to generate non-dominated solutions with a wider spread along the Pareto-optimal front and better address the issues regarding convergence and diversity in multiobjective optimization.
