The Sherali-Adams lift-and-project hierarchy is a fundamental construct in integer programming, which provides successively tighter linear programming relaxations of the integer hull of a polytope. We initiate a new approach to understanding the Sherali-Adams procedure by relating it to methods from computational algebraic geometry. Our two main results are the equivalence of the Sherali-Adams ...

Attempts to apply methods of statistical thermodynamics to turbulent flows have usually been based on wave number decomposition of an Eulerian velocity field. ' Intermittency, which involves spatially localized phenomena and hence phase correlations, is notoriously difficult to treat in this way. An essential feature of turbulence is the randomization of positions of fluid elements, in the sens...

This document describes the design and implementation of the ADAMS Storage Management System. The system consists of a server that manages connections with multiple clients and passes storage requests to I/O-dedicated processes. The communication channels between clients and the server are implemented through sockets, the basic interprocess communication facility in BSD UNIX†. The interface pro...

In recent work, various algebras of stable degree zero operations in p-local K-theory were described explicitly [5]. The elements are certain infinite sums of Adams operations. Here we show how to make sense of the same expressions for MU(p) and BP , thus identifying the “Adams subalgebra” of the algebras of operations. We prove that the Adams subalgebra is the centre of the ring of degree zero...

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

Recently, a segment of the Adams-Shuswap sockeye salmon (Oncorhynchus nerka) population initiated freshwater migration several weeks earlier than historically recorded, resulting in high mortality rates. The comigrating Chilko population maintained their historic river entry timing and did not experience elevated mortality. To test the hypothesis that population-specific differences in physiolo...
