The purpose of this paper is to improve the precision of gangue detection. In the real production environment, some gangue features are not obvious, and it is difficult to distinguish between coal and gangue. The color of the conveyor belt is similar to the gangue, the background noise also brings challenge to gangue detection. To address the above problems, we propose a feature aggregation method based on optical flow (FAOF).

An FAOF is proposed. First, to enhance the feature representation of the current frame, FAOF applies the timing information of video stream, propagates the feature information of the past few frames to the current frame by optical flow. Second, the coordinate attention (CA) module is adopted to suppress the noise impact brought by the background of convey belt. Third, the Mish activation function is used to replace rectified linear unit to improve the generalization capability of our model.

The experimental results show that the gangue detection model proposed in this paper improve 4.3 average precision compared to baseline. This model can effectively improve the accuracy of gangue detection in real production environment.

The key contributions are as follows: this study proposes an FAOF; this study adds CA module and Mish to reduce noise from the background of the conveyor belt; and this study also constructs a large gangue data set.

In order to solve the current imbalance of academic resources within the discipline, this article builds a three-dimensional talent evaluation model based on the topic–author–citation based on the z index and proposes the ZAS index to evaluate scholars on different research topics within the discipline.

Based on the sample data of the CSSCI journals in the discipline of physical education in the past five years, the keywords were classified into 13 categories of research topics including female sports. The ZAS index of scholars on topic of female sports and so on was calculated, and quantitative indexes such as h index p index and z index were calculated. Comparative analysis of the evaluation effect was performed.

It is found that compared with the h index and p index, the z index achieves a better balance between the quantity, quality and citation distribution of scholars' results and effectively recognizes that the citation quality is higher and the number of citations of each paper is more balanced. In addition, compared to the z index, this article is based on a ZAS index model with an improved three-dimensional topic–author–citation relationship in research fields such as female sports.

It can identify some outstanding scholars who are engaged in small-scale or emerging topic research such as female sports and are excellent in different research areas. Talents create an objective and fair evaluation environment. At the same time, the ranking ability of ZAS indicators in the evaluation of talents is the strongest, and it is expected to be used in practical evaluations.

In an international merger and acquisition, the merged company often faces many difficulties. If we look into this case, China’s Fosun took many measures to conquer barriers and set a solid foundation: aligning the strategy of the company, choosing the allies, understanding local legal system as well as taking special measures concerning the real conditions. These together raise the possibility for Chinese companies to overcome international challenges.

The paper provides strategic insights and practical thinking that have influenced some of the world’s leading organizations.

The briefing saves busy executives and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

The purpose of this paper is to examine the impact of Chinese youth’s attention to and involvement with Chinese soccer and its professional league, the Chinese Super League (CSL), on their level of satisfaction.

A survey study was employed to test the hypotheses. Research participants (n=948) were students from five major universities that represented each of the five main geographic regions of China. Data were randomly assigned into two halves: one half for CFA (n=474) and the other half for structural equation modeling (SEM) (n=474). Mplus 7.0 was used to conduct both the CFA and SEM.

The findings of this study indicated an overall lack of attention to and involvement with Chinese soccer and CSL among Chinese youths. Discussions have been presented on the causes of the lack of youth passion for Chinese soccer and suggestions have been articulated to improve the effectiveness and efficiency of policy formulation, business operation and marketing strategy.

The present study built on the extant sport management literature, demonstrated the complexity of consumers’ cognition and conation in the professional soccer setting, and revealed counter-intuitive relationship between attitudinal traits and behavioral patterns, which in turn provided unique insights for Chinese professional soccer marketers, managers and administrators.

Built upon the balance theory and schema theory, this study examined the impact of sponsors' intangible attributes, including consumer-based brand equity (CBBE) and brand-event image fit (BEIF), on consumer responses to emerging local events (ELEs), as well as major boundary conditions of this mechanism.

Theoretical hypotheses were tested using multivariate analysis of covariance and structural equation modeling with the data from two experiments: the experiment in the pilot study was used to calibrate sponsor stimuli, and the experiment in the main study was designed to assess consumer responses to different sponsor-event combinations.

Results of this experimental study illustrated the dominant role of CBBE in influencing individuals' perceived event value and intention to participate in the context of ELEs and revealed the noticeable but limited moderating effects of BEIF and sport identification.

This study highlighted the importance of sponsorship in the marketing communications of ELEs and suggested prioritizing the overall attributes of sponsors in the sponsor-selection. This study also called for more research attention directed toward the intangible benefits that sporting events could receive from sponsorship deals.

The current study was designed to (1) identify core and peripheral market demand for a recurring hallmark sporting event, testing their impact on event identification and behavioral intentions; and to (2) explore the effect of core and peripheral market demand on event identification between first-time and repeat spectators.

Research participants (N = 540) were spectators at the Shanghai Masters over a span of seven days. Data were analyzed using partial least squares structural equation modeling (PLS-SEM) and partial least squares multi-group analysis (PLS-MGA).

Significant, positive relationships were found between core market demand and event identification, and between core market demand and behavioral intentions. In contrast, peripheral market demand only had significant, positive effect on event identification; however, findings revealed that event identification fully mediated the relationships between peripheral market demand and behavioral intentions. Additionally, the effect of peripheral market demand on event identification was greater among first-time spectators than repeat spectators.

This study contributed to the application of PLS-SEM in sport management research by adopting a formative-formative hierarchical component model (HCM) to address the prevailing measurement model misspecification of market demand constructs. The findings highlighted the merits of promoting market demand associated with recurring hallmark sporting events and the importance of enhancing event identification through differential market penetration schemes across different spectator groups.

The occupational health risk associated with the production of prefabricated concrete components is often overlooked. This paper will use a damage assessment and cyclic mitigation (DACM) model to provide individualized exposure risk assessment and corresponding mitigation management measures for workers who are being exposed.

The DACM model is proposed based on the concept of life cycle assessment (LCA). The model uses Monte-Carlo simulation for uncertainty risk assessment, followed by quantitative damage assessment using disability-adjusted life year (DALY). Lastly, sensitivity analysis is used to identify the parameters with the greatest impact on health risks.

The results show that the dust concentration is centered around the mean, and the fitting results are close to normal distribution, so the mean value can be used to carry out the calculation of risk. However, calculations using the DACM model revealed that there are still some work areas at risk. DALY damage is most severe in concrete production area. Meanwhile, the inhalation rate (IR), exposure duration (ED), exposure frequency (EF) and average exposure time (AT) showed greater impacts based on the sensitivity analysis.

Based on the comparison, the DACM model can determine that the potential occupational health risk of prefabricated concrete component (PC) factory and the risk is less than that of on-site construction. It synthesizes field research and simulation to form the entire assessment process into a case-base system with the depth of the cycle, which allows the model to be continuously adjusted to reduce the occupational health damage caused by production pollution exposure.

The purpose of this paper is to achieve optimal climbing control of the gas-insulated switchgear (GIS) robot, as the authors know that the GIS inspection robot is a kind of artificial intelligent mobile equipment which auxiliary or even substitute human labor drive on the inner wall of the gas-insulated metal enclosed switchgear. The GIS equipment fault inspection and maintenance can be realized through the robot manipulator on the mobile platform and the camera carried on the fuselage, and it is a kind of intelligent equipment for operation. To realize the inspection and operation of the GIS equipment pipeline without blind spots, the robot is required to be able to travel on any wall inside the pipeline, especially the top of the pipeline and both right and left sides of the pipeline, which requires the flexible climbing of the GIS inspection robot. The robot device has a certain adsorption function to ensure that the robot is fully attached to the wall surface. At the same time, the robot manipulator can be used for collision-free obstacle avoidance operation planning in the narrow operation space inside the GIS equipment.

The above two technologies are the key that the robot completes the GIS equipment inspections. Based on this, this paper focuses on modeling and analysis of the chassis adsorption characteristics for the GIS inspection robot. At the same time, the Denavit Hartenberg (D-H) coordinate model of the robot arm system has been established, and the kinematics forward and inverse solutions of the robot manipulator system have been derived.

The reachable working space point cloud diagram of the robot manipulator in MATLAB has been obtained based on the kinematics analysis, and the operation trajectory planning of the robot manipulator using the robot toolbox has been obtained. The simulation results show that the robot manipulator system can realize the movement without collision and obstacle avoidance. The space can cover the entire GIS pipeline so as to achieve no blind area operation.

Finally, the GIS inspection robot physical prototype system has been developed through system integration design, and the inspection, maintenance operation experiment has been carried out in the actual GIS equipment. The entire robot system can complete the GIS equipment inspection operation soundly and improve the operation efficiency. The research in this paper has important theoretical significance and practical application value for the optimization design and practical research of the GIS inspection robot system.
