Engineering design is an iterative process with a fundamental need for the consistent management and propagation of product dependencies. Constraint-based design provides a unified framework to meet this critical need, but there are known issues due to the complexity of the problem within three-dimensional space. This paper presents results from a decade of(More)
Electrophoresis gel analysis is a viable technique for determining the purity of hybrid corn seeds. Visually analyzing the electrophoretic gel images is a very tedious and time-consuming task. In this paper, a computer vision system integrating image processing and pattern recognition techniques with domain-specific structural information to automate the(More)
Diffusion-limited aggregation (DLA) is a useful model for studying such common physical phenomena as dust clustering, unstable fluid flowJ chemical species precipitation, and crystal growth. Simulating the DLA processes using electrostatic analogy is very computation-intensive. Elimination of closed loops in DLA images can significantly reduce the(More)
The pole-placement self tuning control method is applied to the control of manipulators directly in the task coordinate system. This results in highly desirable task-oriented performance characteristics. In the task coordinate, the position control axes and the force control axes are orthogonal. Therefore hybrid control can be achieved without degradation(More)
