In the article we solve path planning task for an agent being multirotor unmanned aerial vehicle (multicopter). We propose an approach of estimating path geometry constraints based on UAV flight dynamics model and control constraints. Than we introduce a new path finding method which takes into consideration those geometry constraints and study this method both theoretically and empirically.  相似文献

Counselors (N = 911) reported the research skills needed for practice and subsequent research training needs. Findings indicate that counselors have a high need for research skills at work, but training needs differ significantly by counselor type. Recommendations include increasing emphasis on single‐case design, survey design, and widely available data analysis tools.  相似文献

All universities in Australia are asked to develop various attributes in their degrees. From 2011, the Australian Qualifications Framework has stipulated some of these attributes for the various levels of qualifications. There are many challenges that face assuring the development of graduate attributes in a Bachelor of Arts as the degree typically has very few core units (if any), a wide choice of subjects, a limited prerequisite structure and, unlike many professional degrees, the BA does not have an external accrediting body. This paper describes an approach used to identify the pathway undertaken by each individual student in a History major of the Bachelor of Arts. This pathway was used to identify the graduate attributes that each student should have developed, as articulated by the lecturers. Student perceptions were then compared with the graduate attributes that were intended to be developed through each individual's combination of units studied. In summary, through analysing the two methods (student perceptions and unit pathway) we found that they concurred with respect to only three-quarters of the graduate attributes. Possible reasons for the discrepancies and future research are discussed. The need for multiple methods of providing evidence of the development of graduate attributes is confirmed.  相似文献

Through a qualitative interview design, this study investigated how participation in a rigorous academic environment may influence gifted students who demonstrate high levels of perfectionism. The study also examined how their responses to a rigorous academic and residential environment may differ according to the type of perfectionism. Findings indicated that some socially prescribed perfectionists reported an increase in perfectionism, whereas some self-oriented perfectionists reported an increase followed by a decrease in their perfectionism. Overall, the majority of the participants, regardless of their type of perfectionism, indicated a decrease in their perfectionism as a result of their new academic environment. Reactions to experiencing imperfections ranged from calm to guilt or even anger, depending on the type of perfectionism. Implications for working with gifted students who show high levels of perfectionism are discussed.  相似文献
