This paper addresses the problem of encircling and tracking a moving target with a fleet of unicycle-like vehicles. A new control law is developed to steer the vehicles to an evenly spaced formation along a circumference, the center of which tracks the motion of the target. The strategy proposed relies only on the relative positions of the agents with respect to the target, expressed in the local frame of each vehicle. The absolute position, velocity and acceleration of the target are unknown. Additionally, the robustness of the proposed control law in the presence of external disturbances is analyzed. Communication among agents is used to maintain the vehicles equally spaced in the circular formation. Simulation results illustrate the effectiveness of the proposed strategies.  相似文献

The number of students with mental health disorders (MHDs) in postsecondary institutions is increasing. Teachers’ attitudes are among the main factors that influence these students’ academic success. Unfortunately, their attitudes are little studied, in part because of lack of validated scales. Therefore, this article has two purposes: (1) analyse the construct validity of new scales assessing teachers’ attitudes, as well as existing scales without an established construct validity; and (2) report the correlations between the variables assessed in these scales, with a special focus on two variables: (a) teachers’ negative attitudes; and (b) the measures offered to students by teachers. The participants are 232 teachers from 16 French and English CEGEPS in Quebec, Canada. The questionnaire includes three scales created by the research team and three scales from the Mental Illness Awareness Survey. Correlational and factor analyses were conducted. The scales present good construct validity. Four variables were associated with the two variables of interest: confidence in one’s ability to convince a student to seek help; familiarity with MHDs; knowledge and understanding of MHDs; favourable perception of the accommodations offered by adapted and psychosocial services. Based on these results, strategies are proposed to improve teachers’ attitudes.  相似文献

Methodologies for engineering learning and teaching (MELT) approach aims to enhance the attractiveness of education through science, technology, engineering and mathematics (STEM) among young people, while promoting awareness of future careers in these areas. To this end, students’ expectations are considered within university programmes, aiming to an increased engagement in STEM careers. To accomplish these goals, a new and integrated approach (MELT) is presented, involving the main stakeholders in both scientific education and society. An education framework is presented, providing guidelines for an improved collaborative approach to STEM education in the future. Results from the pilot implementation of MELT are presented, from a small-scale education parliament prototype. From these initial stage and results, it is seen that there is a need for a proper alignment of expectations from all involved stakeholders, concerning the engineering education towards society’s demands.  相似文献

The study aimed to test the validity and reliability of the Very Short form of the Physical Self-Inventory (PSI-VS) among a sample of 635 Turkish adolescents. These adolescents have completed the 12 original items of the PSI-VS, plus a positively worded reformulation of the single reverse-keyed item of the physical attractiveness subscale. A series of confirmatory factor analyses was used to examine the psychometric properties of the original and modified versions of the PSI-VS. Findings revealed superior psychometric properties with the modified version than with the original set of items. The modified version was thus subsequently used to examine its factor structure invariance across sexes, age groups and sport practice involvement. Results not only report that this version was fully invariant across, but also that latent means were significantly different across sexes and sport practice involvement. In sum, the Turkish modified version of the PSI-VS presents acceptable psychometric properties and may be used to repeatedly and/or intensively assess participants’ physical self-perceptions in the context of sport and exercise interventions.  相似文献
