Given the gaps in the link between leadership, knowledge resource, and innovation capability, this study aims to examine the potential mediating role of knowledge sharing and moderating role of knowledge-centered culture in the relationship between transformational leadership and a firm’s capability for innovation. This study applied the Structural Equation Modeling to try out proposal hypotheses in the research model through a questionnaire survey from a sample of 301 participators in 115 small and medium firms in the field of tourism and hotel. The findings disclosed that knowledge-sharing behaviors significantly mediate the transformational leadership-innovation relationship. It highlights the significant impact of explicit knowledge sharing in comparison with the influence of tacit knowledge sharing on innovation capability. The paper also reveals the crucial role of knowledge-centered culture in boosting the knowledgesharing- innovation relationship. By exploring the mediating role of knowledge sharing and the moderator of knowledge-centered culture, the paper significantly brings insight into different mediating and moderating mechanisms to improve innovation capability. The paper significantly fills up the gaps and provides valuable initiatives on the mechanism of how transformational leadership and specific forms of knowledge-sharing behaviors positively affect innovation capability under the moderating role of knowledge-centered culture.
OROMACS: A Design Framework for Multi-agent Control System
Phong Ba Dao 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.5
This paper presents a controller-agent-based design framework (named OROMACS) for the construction of hierarchically structured multi-agent control system (MACS). OROMACS uses the decentralized coordinationmechanism to build MACS. Each MACS can be in the form of an elementary controller-agent or a compositecontroller-agent. The latter consists of a group of elementary and/or composite controller-agents and a coordinator; the coordinator has a role to coordinate the activity behaviour of the whole group. The main idea in creatingcomposite controller-agents is to consider a group of coordinated controller-agents as if it is an individual controlleragent. Then, a composite controller-agent can be used in other groups, leading to hierarchical structures of MACS. To provide real-time features for MACS, the OROMACS framework has used the real-time OROCOS softwareframework as running environment. The OROMACS-based design method is illustrated through a design of MACSfor a single-axis electro-mechanical motion system using a linear motor with the dominant compliance in the transmission. The process starts with the design of an Operation Controller Agent and then reusing its whole designto develop a more complex system called Safe-Guarded MACS. Software-In-the-Loop (SIL) co-simulation resultshave demonstrated the applicability of the design method.
CMOT : Collaborate Multi Object Tracking Using Stereo Camera
Phong Phu Ninh,Hyungwon Kim 한국차세대컴퓨팅학회 2022 한국차세대컴퓨팅학회 학술대회 Vol.2022 No.10
Multi-object tracking techniques are receiving increasing attention due to the growing demand of autonomous driving. Recently, the performance of multi-object tracking has been improved significantly thank to deep learning technique. Most of multi-object tracking methods based on deep learning, however, are highly prone to frequent tracking losses and track-ID switching in case of limited viewpoint and occluded objects. To alleviate this problem, we propose a multi-camera Collaborate Multi Object Tracking (CMOT) method which performs online association of multiple tracked vehicles from stereo vision camera. CMOT not only provides global tracking IDs between multiple cameras but also helps reduce the problem of ID switching compared with the conventional multi-object tracking based on single camera. It can, therefore, improve the overall performance of multi-vehicle tracking compared to each individual camera. We demonstrate the multi-object tracking performance of the proposed method using stereo images of the KITTI dataset.
