Based on the characteristics of high-end products,crowd-sourcing user stories can be seen as an effective means of gathering requirements,involving a large user base and generating a substantial amount of unstructured feedback.The key challenge lies in transforming abstract user needs into specific ones,requiring integration and analysis.Therefore,we propose a topic mining-based approach to categorize,summarize,and rank product requirements from user stories.Specifically,after determining the number of story categories based on py LDAvis,we initially classify“I want to”phrases within user stories.Subsequently,classic topic models are applied to each category to generate their names,defining each post-classification user story category as a requirement.Furthermore,a weighted ranking function is devised to calculate the importance of each requirement.Finally,we validate the effectiveness and feasibility of the proposed method using 2966 crowd-sourced user stories related to smart home systems. 展开更多

Linguistic landscape has become an emerging research topic in sociolinguistics due to the development of urban linguistic landscape.Based on the development of linguistic landscape in TaiKoo Hui,its diverse characteristics are analyzed,and the language signs,usage,and codes are summarized.It is found that there is poor transmission effect of multilingual landscape information and improper use of linguistic landscape in TaiKoo Hui.This paper concludes that the linguistic landscape of Taikoo Hui can be optimized from two aspects to enhance its attractiveness and competitiveness,including improving the informational function of foreign language signs and regulating the use of linguistic landscape. 展开更多

The high-end equipment represented by high-end machine tools and aero-engines is the core component of the national intelligent manufacturing plan,and the mass unbalance is the main reason for its excessive vibration,that seriously impacts the operation efficiency and running life of the equipment.In order to change the traditional way that the fault of equipment can only be repaired by human,the self-recovery mechanism of human and animal are given to the equipment in this paper,which forms the self-recovery regulation(SR)system for unbalance vibration of high-end equipment.The system can online generate the self-recovery force to restrain the unbalance vibration of the equipment in operation,which is an important direction for the development of the equipment to the advanced intelligent stage.Based on the basic principles of SR technique,the typical engineering application cases of this technique in the field of aeroengine and high-end machine tools are introduced,and four related studies promoting the development of this technique are summarized and analyzed in turn.It includes feature extraction,imbalance location,regulation method and balancing actuator.Self-recovery Regulation(SR)Technique is an important way to realize intelligent manufacturing and intelligent maintenance.Relevant research can lay a technical foundation for the development of high-end equipment with self-health function. 展开更多

Decomposition of tasks and selection of optimal schemes are key procedures in high-end equipment development processes.However,such procedures are highly innovative,technology intensive,interdisciplinary,and multi-party engineering projects,making the decomposition and scheme selection more difficult and complicated than that in the development of ordinary equipment.In this study,we consider three factors,namely,functional structure,task granularity,and task feasibility in task decomposition of high-end equipment development.Based on the principles of systems engineering,a method of task decomposition is proposed.As for decomposition scheme selection,a method based on the superiority and inferiority ranking(SIR)method mixed information and multiple attribute decision making is proposed by considering attributes of scheme feasibility,uncertainty risk and task integration complexity.To verify the proposed method,development of a military electric vehicle is used as an example to demonstrate the calculation process. 展开更多

The paper illustrates the reason of the lack of talents with outstanding innovative practice ability and engineering leadership has become a great obstacle for many industries, represented by the software industry, to develop along with the new era, and restricted the evolution of these industries toward the high end. With the target of training talents with innovation capacity and engineering leadership, the training plan for top talents based on the demand for high-end talents in the software engineering industry is put forward, and analyses are given on significant aspects including the development of the training resource system, the screening of students and the selection of enterprises, the teaching staff construction for university-enterprise cooperation, the establishment of a management system with joint effort for talents development, and the construction of process quality guarantee mechanism. In the end, for the implementation of the training plan, it is pointed out that the university-enterprise cooperative development mechanism should be perfected, the talents development practice should be enhanced, the personalized training of students should be emphasized, and the innovative ability in practice and the engineering leadership of students should be practically improved. 展开更多

The main purpose of this paper is to explore the intermediary role of policy incentives and marine technological innovation in marine high-end human capital promoting marine knowledge innovation.Previous studies on the impact of marine high-end human capital on marine knowledge innovation mainly focused on the direct impact of marine high-end human capital on marine knowledge innovation,while ignoring the role of intermediary variables.Based on 512 sample survey data from 138 organizations in 16 coastal cities of China,this paper uses structural equation model to examine the relationship between high-end human capital and policy incentives,technological innovation and marine knowledge innovation.The research shows that marine high-end human capital has an impact on marine knowledge innovation through policy incentives and marine technology innovation.Policy incentives and marine technology innovation play a full intermediary role in the relationship between marine high-end human capital and marine knowledge innovation. 展开更多
