A sensor network localization problem can be formulated as a quadratic optimization problem (QOP). For quadratic optimization problems, semidefinite programming (SDP) relaxation by Lasserre with relaxation order 1 for general polynomial optimization problems (POPs) is known to be equivalent to the sparse SDP relaxation by Waki et al. with relaxation order 1, except the size and sparsity of the ...

Human organism needs movement and activity to grow, develop, and maintain health. Advances in modern technology, however, have almost completely eliminated the necessity for physical exertion in daily life. Physical activity is no longer a natural part of our existence. This lack of physical activity has reduced our ability to maintain a healthy body weight and body composition. Recommended bod...

This paper examines the applications most commonly run on the supercomputers at the Numerical Aerospace Simulation (NAS) facility. It analyzes the extent to which such applications are fundamentally oriented to vector computers, and whether or not they can be e ciently implemented on hierarchical memory machines, such as systems with cache memories and highly parallel, distributed memory system...
