Group sparsity reveals underlying sparsity patterns and contains rich structural information in data. Hence, exploiting group sparsity will facilitate more efficient techniques for recovering large and complicated data in ...

The miscible displacement equations provide the mathematical model for simulating the displacement of a mixture of oil and miscible fluid in underground reservoirs during the Enhance Oil Recovery(EOR) process. In this ...

While moment matching can effectively reduce the dimension of a linear, time-invariant system, it can simultaneously fail to improve the stable time-step for the forward Euler scheme. In the context of a semi-discrete ...

This thesis proposes a new proof of the acoustic transparency theorem for material with a bounded variation. The theorem states that if the material properties (density, bulk modulus) is of bounded variation, the net power ...

This study develops a discrete search-based optimization method for path planning in a highly nonlinear dynamical system. The method enables real-time trajectory improvement and singular configuration avoidance in satellite ...

Salt has unusual properties which complicate seismic exploration. A Model study examines some problems encountered in subsalt amplitude analysis and demonstrates that traditional techniques for detecting hydrocarbons and ...

We present a study of the ground and triplet state properties of C$\sb{60}$O. UV-vis spectroscopy and a gravimetric analysis are used to produce a quantitative electronic absorption spectrum. Spectrofluorimetry reveals ...

Absolute differential and integral charge transfer cross sections have been measured for 0.5, 0.85, 1.5, 2.8, and 5.0 keV O$\sp+$ with O$\sb2$ at scattering angles between 0.01$\sp\circ$ and 3.50$\sp\circ$ in the laboratory ...

In this thesis, we propose a spatial domain decomposition method and model reduction techniques for the solution of linear-quadratic parabolic optimal control problems. Such problems arise directly from many applications ...

This work tests the consistency of sequence stratigraphic methods by comparing the model documented in this study with previous models for growth faulted, siliciclastic environments. Interpretations derive from sequence ...
