Several techniques for choosing state assignments which tend to minimize the combinational input and output circuitry of sequential machines have been developed. One of these techniques is a heuristic scoring approach which was originally developed assuming delays as memory elements [1]. This technique was later expanded to cover the cases when trigger flip-flops or combinations of trigger flip...

We give a construction of (n s)-surjective matrices with n columns over Zq using Abelian groups and additive s-bases. In particular we show that the minimum number of rows msq(n, n — s) in such a matrix is at most ssqn-s for all q, n and s.

In this paper, we address a new integration of column generation and Lagrangian relaxation for solving flowshop scheduling problems to minimize the total weighted tardiness. In the proposed method, the initial columns are generated by using near-optimal dual variables for linear programming relaxation of Dantzig-Wolfe decomposition derived by the Lagrangian relaxation method. The column generat...

P reparative chromatography is the dominant purification technique in the production of biological compounds, especially for bioseparations. The column used is central to the performance of the chromatographic step. To ensure robust and reproducible column performance, columns need to be qualified in an acceptable fashion before each use. Some of the critical elements of column qualification in...

This paper compares base shears computed from floor accelerations (inertial base shear) and column shears (structural base shear) for two mid-rise, multi­ story buildings due to a suite of 30 earthquake ground motions. The presented results demonstrate that the inertial base shear exceeds the structural base shear in the median by 10% to 20% and may exceed the structural base shear by as much a...
