  • Quality improvement on minimum-storage-overhead image processing scheme in encrypted domain   Order a copy of this article
    by Shushan Zhao 
    Abstract: Image processing in encrypted domain is needed in many services while many image processing tasks are outsourced to third party cloud computing platforms for data confidentiality and privacy-preserving purposes. There are many solutions for image scaling, cropping and colour correction in this context. However, most of the solutions are not compatible with each other and there is few solutions supporting all these operations. In our previous work (Zhao, 2022), we propose a scheme that supports image scaling, cropping, and colour correction in encrypted domain with minimum storage overhead. We notice that the image quality achieved is not satisfactory in some circumstances, and in this work, we propose a quality improvement solution to address this issue. The new scheme provides satisfactory quality in all cases considered, with 2.6% storage overhead increase as analysis shows in this paper.
    Keywords: image processing; scaling; cropping; colour correction; encrypted domain.

  • Applicability of the design thinking process to the development of capstone project proposals   Order a copy of this article
    by Fernando Cezar Leandro Scramim , Rui M. Lima, Hong Yuh Ching, Denise L. Rieg 
    Abstract: The purpose of this paper is to present an empirical study that explores how design thinking can be applied to develop ideas for capstone projects in undergraduate engineering programs. Action research was the research method used in this study. The collected data consisted of students’ project proposals, grades, classroom observations, and focus group findings. This study has two levels of implications: 1) for the practice of educators, as they can adjust the approach developed to help undergraduate engineering students find a potential idea for a viable and relevant capstone project; 2) for research, thereby adding to the ongoing discussion on exploring the design thinking process as a conceptual structure that provides a basis for dealing with difficult situations and solving complex problems in undergraduate courses.

    by Qian Zhong, Yujie Jiang, Honglin Du 
    Abstract: In order to improve the accuracy of the question answering system, an intelligent question answering system for college distance education based on Chinese word segmentation technology is proposed and designed. First, the overall architecture of the intelligent question answering system for distance education in colleges and universities is designed, and then the user login display module, Chinese word segmentation module, algorithm module and other functional modules are designed. Finally, the system software is designed to optimise Chinese word segmentation technology through heuristic rules and pruning methods.

  • Non-technical skills in engineering education as a concept   Order a copy of this article
    by Christin Lindholm, Christian Nyberg, Ylva Oscarsson 
    Abstract: To have a successful career in engineering, students need both technical engineering skills and non-technical engineering skills (NTES) in the transition to professional life. To address NTES in engineering education, the concept of six compulsory engineering days were introduced in two engineering programs at the undergraduate level. The importance of different NTES for industry has been evaluated through a survey with industry representatives. The results from the survey support the assumption that NTES are important when working as an engineer. The concept of engineering days has also been evaluated through a survey that was taken by the final-year students. Overall, the student survey showed that the students understood what the purpose of the concept of engineering days was, and that the students estimated that they had increased their NTES. With this work, we hope to inspire teachers to focus on non-technical skills as well as technical skills.

    by Lin Zeng 
    Abstract: Aiming at the problem that the evaluation error is large due to the high data dimension when evaluating the impact of AI technology application on the quality of wisdom teaching, an evaluation method based on principal component analysis (PCA) is proposed. First, the evaluation indicators were selected to build an evaluation index system. Then, covariance and sensitivity were used to improve the PCA method and reduce the data dimension. Finally, BP neural network (BPNN) was improved by steepness factor and weight adjustment to build an evaluation model for the impact of wisdom teaching quality. The experimental results show that the evaluation error of this method is up to 0.02, the satisfaction of the respondents is 96%, and the coefficient of goal achievement is 0.99, so the evaluation effect is good.

    Abstract: In response to the problems of low execution efficiency and high probability of multi classification loss in the classification mining of online teaching data in universities, this paper proposes a decision tree algorithm based method for classification mining of online teaching data in universities. This method calculates multi class losses through an unbiased risk estimator and minimizes the difference between real and non real labels for data preprocessing. Then, based on the complexity of experience, the degree of feature fitting is considered to determine the set of feature data, and redundant features are removed from the perspective of two-dimensional real space for feature extraction. Finally, use decision tree algorithm for classification mining. The experimental results show that this method improves execution efficiency and reduces the risk of data loss.

  • Personalised recommendation method for MOOC online educational resources: collaborative filtering algorithm   Order a copy of this article
    by Min Fan 
    Abstract: In order to address the practical challenges associated with the low recall rate, accuracy, and user satisfaction in conventional personalised recommendation approaches for educational materials, a personalised recommendation method for MOOC online educational resources based on collaborative filtering algorithm is proposed. The mean shift clustering algorithm is used for clustering processing of MOOC platform data, and the MFA algorithm is used to dimensionality reduction process the clustering results. Learner interest are determined by considering the label preference based on frequency weight, time weight, comprehensive frequency and time, as well as learners’ interest preferences for label clusters. Based on the analysis of learner interest, personalised recommendation of MOOC online education resources is achieved using a collaborative filtering algorithm based on semi-supervised learning. Experimental results show that the maximum recall rate of this method is 98.3%, the maximum recommendation accuracy is 97.8%, the mean learner satisfaction is 97.95, indicating good recommendation effectiveness.
