Printed circuit boards (PCBs) are extensively used in diverse electronic products today. The placement process is generally the bottleneck in a PCB assembly line. Many researchers have indicated that an optimal component placement sequence reduces the cycle time of an assembly line with single placement machines. However, in current PCB assembly lines, more than one placement machine, including...

The problem of optimal design of the assembly lines is considered. The paper is especially focused on the line balancing and resource planning step for the preliminary design stage. A survey of existing methods and software tools are given. Copyright © 2002 IFAC

I am a first year PhD student in Materials Science and Engineering. I did my Bachelor’s and my Master’s at the University of Arizona, with an emphasis on computational materials for the latter, and my thesis dealt with automating the analysis of dendritic metal micrographs using computer vision techniques. My current research, although still in its infancy, will involve the modeling of liquid s...

Self-assembling DNA nanostructures are an efficient means of executing parallel molecular computations. However, previous experimental demonstrations of computations by DNA tile self-assembly only allowed for one set of distinct input to be processed at a time. Here, we report the multibit, parallel computation of pairwise exclusive-or (XOR) using DNA "string tile" self-assembly. A set of DNA t...
