To this simplified tumor model, a nearest neighbor search method is used to determine intermediate configuration and goal configuration, which the treatment head and ultrasound focus must pass in their localization to target volume. Based on the decided configurations, the continuity condition of combined Bezier curve in Euclidean space and De Casteljau algorithm on Lie group SO(3) are integrated to construct a combined Bezier positioning path of C2 continuity at junctional configuration, and an illustration of different positioning path planning is analyzed based on a liver tumor case.展开更多

Through the investigation of two recent approaches, the Italian and the American ones, the complex relationships between daily practices and urban spaces, in the continuous redefinition of the concepts of public and private sphere, are described. In this context, the Everyday Urbanists' work had the merit to reveal and investigate the social possibilities offered by the patterns of everyday life. They were among the first to speak about a citizenship redefinition, process which has been increasingly debated by many scholars. Citizenship is thus turning to be less formal, while becoming more substantive and insurgent. The paper demonstrates that, according to this crucial change, new and meaningful relations between citizenship and planning can be established and that these are able to open planning practice up to the present ethnographical possibilities of the urban space, and to its tactical and polysemic dimensions.展开更多

They have explored the application of these perspectives to the central substantive theme emerging from global educational analysis of planning organisation and behaviour, that is, the process of managerial control. This study focuses upon the global educational environment within global management of knowledge and substantive parameters set by the previous studies.

First, it reviews the various explanations that have been offered for the historical development of modern planning--both as a unique organisational form and as a distinctive educational worldview.

文摘A positioning volume ellipsoid method is proposed to represent tumor volume in the workspace of a high-intensity-focused ultrasound (HIFU) surgery platform during the platform's positioning motion. To this simplified tumor model, a nearest neighbor search method is used to determine intermediate configuration and goal configuration, which the treatment head and ultrasound focus must pass in their localization to target volume. Based on the decided configurations, the continuity condition of combined Bezier curve in Euclidean space and De Casteljau algorithm on Lie group SO(3) are integrated to construct a combined Bezier positioning path of C2 continuity at junctional configuration, and an illustration of different positioning path planning is analyzed based on a liver tumor case.
