Description: This award is for support of a cooperative research by Dr. William Wolovich, Division of Engineering at Brown University and Dr. Aytul Ercil, Department of Industrial Engineering at Bogazici University in Istanbul, Turkey. They plan to extend and apply recent advances made in the US and Turkey on implicit polynomials (IP) technology in order to improve the ways manufactured objects are modeled, identified, measured, aligned, designed and fabricated. Specifically, they plan to apply and extend the new IP technologies, including conic-line factorizations and related-point ratios, 3L and PIM fitting algorithms, boundary curve blending procedures, and new scaling and shaping methods to a wide variety of manufactured objects. They will investigate: the use of IP models and their algebraic invariants for rapid and accurate object identification and alignment; 3L fitting of experimental (vision and CMM) data to obtain useful IP models for reverse engineering and metrology; physical fabrication (CAM) of 3D objects modeled using IP equations; new ways of controlling a CMM while maintaining proper tool tip orientations; use of IP curve blending to enhance industrial design, including the various ways that IP curves and surfaces can be scaled and shaped to produce simple and innovative designs; and identification and reconstruction of 3D objects from 2D boundary information. Scope: the U.S. PI is well known and his laboratory is recognized in this field. The Turkish scientist, who also received her doctorate at Brown, is a professor at one of Turkey's best universities. At least two, and possibly three, graduate students from Brown University will have opportunities to work in this international collaboration. They will be joined by a similar number of graduate students from Bogazici University. The two sides have complementary facilities, with Brown offering excellent facilities in the Laboratory for Engineering Man/Machine Systems (LEMS), including workstations dedicated to experiments in 3D object visualization, and a state-of-the-art Chameleon Coordinate Measuring Machine (CMM) with both mechanical and laser scanning probes. The Industrial Engineering Department at Bogazici is using excellent visual facilities that were developed by Dr. Ercil, and used in collaboration with industrial partners. This proposal meets INT objective of supporting US-foreign collaboration in areas of mutual benefit.

产品描述：该奖项是为了支持布朗大学工程系的William Wolovich博士和土耳其伊斯坦布尔Bogazici大学工业工程系的Aytul Erdegli博士的合作研究。 他们计划扩展和应用美国和土耳其在隐式多项式（IP）技术方面取得的最新进展，以改善制造对象的建模，识别，测量，对齐，设计和制造方式。 具体来说，他们计划应用和扩展新的IP技术，包括圆锥线分解和相关点比率，3L和PIM拟合算法，边界曲线混合程序，以及新的缩放和成形方法，以适应各种各样的制造对象。 他们将调查：使用IP模型及其代数不变量进行快速准确的对象识别和对齐; 3L拟合实验（视觉和CMM）数据以获得用于逆向工程和计量的有用IP模型;使用IP方程建模的3D对象的物理制造（CAM）;控制CMM同时保持适当的工具尖端取向的新方法;使用IP曲线混合来增强工业设计，包括IP曲线和曲面可以缩放和成形以产生简单和创新设计的各种方法;以及从2D边界信息识别和重建3D对象。 范围：美国PI是众所周知的，他的实验室在该领域是公认的。 这位土耳其科学家也在布朗大学获得博士学位，是土耳其最好的大学之一的教授。 至少有两个，也可能是三个，来自布朗大学的研究生将有机会在这个国际合作工作。 博阿齐奇大学的研究生人数也差不多。 双方拥有互补的设施，布朗在工程人/机系统实验室（LEMS）中提供了一流的设施，包括专门用于3D物体可视化实验的工作站，以及最先进的变色龙坐标测量机（CMM），配备了机械和激光扫描探头。 Bogazici的工业工程部门正在使用由Erdos博士开发的优秀视觉设施，并与工业合作伙伴合作使用。 该提案符合INT支持美国与外国在互利领域合作的目标。
