PDE-Based Medial Axis Extraction and Shape Manipulation of Arbitrary Meshes

Shape skeletonization （i.e., medial axis extraction） is powerful in many visual computing applications, such as pattern recognition, object segmentation, registration, and animation. In this paper, the authors expand the use of diffusion equations combined with distance field information to approximate medial axes of arbitrary 3D differential properties. It offers an alternative solids represented by polygonal meshes based on their but natural way for medial axis extraction for commonly used 3D polygonal models. By solving the PDE along time axis, this system can not only quickly extract diffusion-based medial axes of input meshes, but also allow users to visualize the extraction process at each time step. In addition, the proposed model provides users a set of manipulation toolkits to sculpt extracted medial axes, then use diffusion-based techniques to recover corresponding deformed shapes according to the original input datasets. This skeleton-based shape manipulation offers a fast and easy way for animation and deformation of complicated mesh objects.     

HPM合成及其在苯乙烯阳离子聚合体系中作用

通过利用与金属多氧络合物的相互作用,合成了具有特殊结构与功能的金属多氧络合物催化剂。经过红外表征,说明新合成的催化剂具有典型的金属多氧络合物晶体结构,同时其活性质子也得到了很好的稳定化保护。经过在苯乙烯体系中的聚合实验,发现合成的新型催化剂在引发聚合的同时,也能很好地实现聚合反应的稳定化,便于聚合操作的进行。     

骨髓干细胞的可塑性及其在栓塞性疾病中的应用

栓塞性血管阻塞在急性心肌梗死、脑梗塞、血栓闭塞性脉管炎、糖尿病足等发病过程中起着重要作用。目前临床上针对这些疾病的治疗手段主要有：药物溶栓、血管旁路移植和介入手术等,多年来其治疗方法无实质性进展。上个世纪九十年代人们发现了干细胞新的生物学特性—可塑性,对干细胞可塑性的研究以及相关技术的发展为心脏病、老年痴呆、帕金森等的治疗带来了希望,也为栓塞性疾病的治疗开辟了新途径,有望成为治疗手段之一。     

Systemic Intervention in a University Department: Reflections on Arrested Action Research

This paper reflects on my experience as an insider researcher attempting to use critical systems ideas and practices to promote quality improvement in a university engineering department. Reflection is a key part of learning. This paper is intended to contribute to critically, self-reflective learning for the community of systems practitioners. These reflections on my questions about participation, ethics, politics of process, and the choices and actions resulting from them may help others to formulate their own. The complexity of systems practice places substantial demands on the researcher, particularly in the case of insider, practitioner research. Nevertheless, the exploration of critical systems approaches to critique boundaries and structure ‘problems’ in the core aspects of higher education in locally meaningful ways should continue. While demanding, it still can work to promote learning about authentic quality.
