Abstract

Purpose

This paper aims to introduce an efficient active-simultaneous localization and mapping (SLAM) approach for rover navigation, future planetary rover exploration mission requires the rover to automatically localize itself with high accuracy.

Design/methodology/approach

A three-dimensional (3D) feature detection method is first proposed to extract salient features from the observed point cloud, after that, the salient features are employed as the candidate destinations for re-visiting under SLAM structure, followed by a path planning algorithm integrated with SLAM, wherein the path length and map utility are leveraged to reduce the growth rate of state estimation uncertainty.

Findings

The proposed approach is able to extract distinguishable 3D landmarks for feature re-visiting, and can be naturally integrated with any SLAM algorithms in an efficient manner to improve the navigation accuracy.

Originality/value

This paper proposes a novel active-SLAM structure for planetary rover exploration mission, the salient feature extraction method and active revisit patch planning method are validated to improve the accuracy of pose estimation.

Abstract

Purpose

The purpose of this study is to promote a better understanding of performance assessment (PA) as a managerial means via analyses and discussion of the system and practice in an academic library.

Design/methodology/approach

One existing PA system of a university library is presented. Descriptive analyses of two specific system‐inherent problems, respectively: weighting scheme of the evaluated criteria and disqualification of the immediate supervisor as rater, are conducted. The purpose of PA is addressed with reference to PA and pay linkage. Circular supervision as an effective element to ultimately eliminate individual errors in an administration is discussed.

Findings

The PA system and practice of CL are flawed. First, the weighting scheme of the evaluated categories is so allocated that the least measurable category has the overriding power. Second, the most qualified evaluator (the direct supervisor) is deprived of the numeric rating vote. Third, the end ratings from the PA lead to unfair merit compensation decisions and salary inequity. Finally, the system lacks a circular supervision mechanism to eliminate undefeatable power in the administration.

Originality/value

With concrete examples and data, this study brings to light some serious problems that exist in a PA system. Via in‐depth analyses and discussion of specific issues, it touches upon circular supervision, a core element in a sound administration that needs to be adequately addressed.

Abstract

Purpose

This paper aims to explore the influence of founder shareholders’ resources on the allocation of control rights from the perspective of incomplete contract theory and resource-based theory.

Design/methodology/approach

This paper analyzes newspaper materials with NVivo11on a case of battle for corporate control in Chinese top-listed company-Vanke Group.

Findings

The research shows that human capital is the key resource and the holding proportion of financial resources directly affects the allocation of control rights. At the same time, social capital is unstable and easily broken. At last, institutional environment also affects the degree between the relationship of founder shareholders’ resources and the allocation of control rights. The influence of founder-shareholder resources on the allocation of control rights follows the path of “crisis – founder-shareholder’s resources – founder’s ability - allocation of control rights.”

Research limitations/implications

This study only selects the financial capital, human capital and social capital of Shi Wang, the founder of Vanke, as the analysis object. The study can expand the types of founder shareholder resources to verify and enrich the conclusions.

Originality/value

The current theoretical research in the literature focuses on the necessity of equity and shareholder’s resources versus the control rights. Some key factors and mechanism on the relationship have not been fully clarified. The results of this paper not only extend the combination research of social network and corporate governance, but also provide enterprise founders with references for making reasonable decisions during control battle.

Abstract

Purpose

With the rapid economic development, China has been increasingly paying special attention to its sports and health industries. In October 2014, the State Council raised the goal to upscale the sports industry to the net worth of 5 trillion yuan by 2025. To gain further insights into the current development of tennis in China, especially the development of Women’s Tennis Association (WTA) tennis competitions, an interview with the director of Wuhan Opening Fabrice Chouquet and Mr Guoqing Yi of Wuahan Sport Investment Inc. was conducted. The paper aims to discuss these issues.

Design/methodology/approach

To gain further insights into the current development of tennis in China, especially the development of WTA tennis competitions, an interview with the director of Wuhan Opening Fabrice Chouquet and Mr Guoqing Yi of Wuahan Sport Investment Inc. was conducted.

Findings

The interview comprised a series of topics including motivators of tennis industries in China, the strategic position of China for WTA development, WTA choice of hosting city, effects of WTA competition events toward the hosting city, and the operation of WTA tennis competitions. Integrating the aforementioned topics with Wuhan Tennis Open, the interviewees also provided suggestions toward the future development of tennis industry in China.

Research limitations/implications

This study has several limitations that are of concern to researchers in the future. First, the interviewees of this research came from Wuhan Tennis Open. Though Mr Fabrice used to be the managing director of WTA in Asia, he only knows about women tennis in China, and his viewpoints have their own limitation. Therefore, the interviewee in the future has to be the person who could hold the opinion on tennis development in China at the macro scale. Second, the questions in the interview have a wide scale, but lack depth and penetration. For instance, the interview only relates to the motive of tennis development but does not go deeply into the relation between the above two aspects. Moreover, it mentions the problems related to the tennis development. It only concentrates on the tennis tournaments but does not discuss the tennis culture and the industry. These questions need to be considered when the authors research on the development of tennis in China in the future.

Originality/value

Through the analysis on WTA and tennis in China, the authors can understand the development of sports in China and the Chinese sports industry in recent years.

Abstract

In this chapter, we present our ongoing efforts in developing and sustaining interdisciplinary STEM undergraduate programs at North Carolina A&T State University (NCA&T) – a state-supported HBCU and National Science Foundation (NSF) Historically Black Colleges and Universities Undergraduate Program (HBCU-UP) Institutional Implementation Project grantee. Through three rounds of NSF HBCU-UP implementation grants, a concerted effort has been made in developing interdisciplinary STEM undergraduate research programs in geophysical and environmental science (in round 1), geospatial, computational, and information science (in round 2), and mathematical and computational biology (in round 3) on NCA&T campus. We first present a brief history and background information about the interdisciplinary STEM undergraduate research programs developed and sustained at NCA&T, giving rationales on how these programs had been conceived, and summarizing what have been achieved. Next we give a detailed description on the development of undergraduate research infrastructure including building research facilities through multiple and leveraged funding sources, and engaging a core of committed faculty mentors and research collaborators. We then present, as case studies, some sample interdisciplinary research projects in which STEM undergraduate students were engaged and project outcomes. Successes associated to our endeavor in developing undergraduate research programs as well as challenges and opportunities on implementing and sustaining these efforts are discussed. Finally, we discuss the impact of well-structured undergraduate research training on student success in terms of academic performance, graduation rate and continuing graduate study, and summarize many of the learnings we have gained from implementation and delivery of undergraduate research experiences at HBCUs.

Abstract

Purpose

High residual stress caused by the high temperature gradient brings undesired effects such as shrinkage and cracking in selective laser melting (SLM). The purpose of this study is to predict the residual stress distribution and the effect of process parameters on the residual stress of selective laser melted (SLMed) Inconel 718 thin-walled part.

Design/methodology/approach

A three-dimensional (3D) indirect sequentially coupled thermal–mechanical finite element model was developed to predict the residual stress distribution of SLMed Inconel 718 thin-walled part. The material properties dependent on temperature were taken into account in both thermal and mechanical analyses, and the thermal elastic–plastic behavior of the material was also considered.

Findings

The residual stress changes from compressive stress to tensile stress along the deposition direction, and the residual stress increases with the deposition height. The maximum stress occurs at both ends of the interface between the part and substrate, while the second largest stress occurs near the top center of the part. The residual stress increases with the laser power, with the maximum equivalent stress increasing by 21.79 per cent as the laser power increases from 250 to 450 W. The residual stress decreases with an increase in scan speed with a reduction in the maximum equivalent stress of 13.67 per cent, as the scan speed increases from 500 to 1,000 mm/s. The residual stress decreases with an increase in layer thickness, and the maximum equivalent stress reduces by 33.12 per cent as the layer thickness increases from 20 to 60µm.

Originality/value

The residual stress distribution and effect of process parameters on the residual stress of SLMed Inconel 718 thin-walled part are investigated in detail. This study provides a better understanding of the residual stress in SLM and constructive guidance for process parameters optimization.

Abstract

Purpose

The purpose of this paper is to test the relationship between innovation performance and innovation spillover effects, innovation inputs, innovation outputs and industrial effects.

Design/methodology/approach

The analysis framework including variables such as innovation spillover effect, innovation input, innovation output and industrial effect was constructed. Through the investigation and analysis of the innovation activities of China’s GEM listed companies in 2014–2016, the innovation performance and the above factors were tested.

Findings

The research shows that enterprise performance has a significant positive correlation with innovation input and innovation output, but there is no significant correlation or even negative correlation with innovation environment and industry background such as government support and innovation opportunities, and the spillover effect is significant. The negative correlation is also negatively correlated with innovative human capital investment, company age and company Q.

Originality/value

Innovation is the real source of economic growth, and industrial innovation is the system integration of technological innovation, product innovation, market innovation, etc., which is the basic determinant of national competitiveness.
