The authors address the problem of segmenting and analyzing images of solder balls in integrated circuits. Two methods are explored, one based on projections computed along curved contours derived from the geometry of the problem, and the other using a supervised, feature-based polynomial classification method. High accuracy is required for the machine vision solution to be successful, and the authors have included some considerations concerning subpixel accuracy for the computation of the values of parameters determining the two-dimensional solder ball shapes. The classification technique has performed with satisfactory results on available data.

A configuration map is defined and computed, mapping all configurations of a part before an elementary manipulative operation to all possible outcomes. Configuration maps provide a basis for planning the operation sequences which occur in parts-feeder designs or in more general sensorless manipulation strategies for robots. Sequences of elementary operations are represented as matrix-products of configuration maps for the individual operations. Efficient methods for searching the space of all operations are described. As an example, a class of parts feeders based on a conveyor belt is considered. Parts arrive on the belt in random initial orientations. By interacting with a series of stationary fences angled across the belt, the parts are aligned into a unique final orientation independent of their initial orientation. The planning problem is to create (given the shape of part) a sequence of fences which will align that part. The automated design of such parts feeders is demonstrated.

Bevel-tipped flexible needles can be steered to reach clinical targets along curvilinear paths in 3D while avoiding obstacles. Steering by duty-cycled rotation increases the versatility of this approach by providing proportional control of trajectory curvature. This paper presents computationally efficient techniques for path planning and path-following control for this application, using a 3D simulated brain environment. Path planning algorithms for this class of steerable needles have been developed using Rapidly-exploring Random Trees (RRTs). This paper expands on these methods, using quaternions for representation of rotation, and enhancing computational efficiency through use of interpolation, and by relaxing the entry constraint. For path-following, a look-ahead proportional controller for position and orientation is presented. Simulations in a 3D brain-like environment demonstrate the performance of the proposed planner and path-following controller. The look-ahead is seen to improve path-following performance.

This paper proposes a distributed fault detection and diagnosis method based on Principal Component Analysis (PCA) in a whole plant monitoring scheme. The method is based on the decomposition of the plant into multiple blocks using plant topology. A local PCA based fault detection method is applied in each block and the results are sent to the central node to fuse the information and to detect and diagnose faults in the global plant. This method is compared with the centralized PCA method and some distributed principal component analysis (DPCA) methods in a wastewater treatment plant (WWTP). The objective is to check which of the distributed methods implemented is the best one in terms of detecting faults and minimizing the communication cost between the blocks. Empirical results on the WWTP show that the DPCA method based on local models has very good results.
