In this study we compare the cycle-time and on-time-delivery performance of the Critical Ratio (CR), the Earliest Due Date (EDD), and the Operation Due Date (ODD) dispatching rules in semiconductor wafer manufacturing. In addition, we comment on the robustness of the rules to low target flow factor values. It turns out that EDD has almost no positive effect on on-time delivery compared to First...

Magnitude is an invariant of metric spaces with origins in enriched category theory. Using potential theoretic methods, Barceló and Carbery gave an algorithm for calculating the magnitude of any odd dimensional ball in Euclidean space, and they proved that it was a rational function of the radius of the ball. In this paper an explicit formula is given for the magnitude of each odd dimensional b...

A persistent artifact in the images acquired by the echo-planar imaging (EPI) method is the Nyquist or N/2 ghost which interferes with the image and reduces the signal-to-noise ratio (SNR). The Nyquist ghost is the result of the time-reversal asymmetry between the even and odd echoes. To eliminate this artifact, the authors present a double-sampled EPI (DSEPI) method in which echoes from each e...

We define and study odd analogues of classical geometric combinatorial objects associated to permutations, namely Schubert varieties, diagrams, inversion sets. show that there is a bijection between sets permutations acyclic orientations the Turán graph, dimension variety permutation length permutation, give several necessary conditions for subset [n]×[n] be diagram permutation. also sign-twist...
