FORMULATION AND ESTIMATION OF STOCHASTIC FRONTIER PRODUCTION FUNCTION MODELS
- A. U.S.
- 2001
Previous studies of the so-called frontier production function have not utilized an adequate characterization of the disturbance term for such a model. In this paper we provide an appropriate… Expand

Predictability , Complexity , and Learning
- A. U.S.
- 2002
We dene predictive information Ipred(T) as the mutual information between the past and the future of a time series. Three qualitatively different behaviors are found in the limit of large… Expand

D-brane Field Theory on Compact Spaces
- A. U.S.
- 1996
We consider Dirichlet p-branes in type II string theory on a space which has been toroidally compactified in d dimensions. We give an explicit construction of the field theory description of this… Expand

Level truncation and the tachyon in open bosonic string field theory
- A. U.S.
- 2000
The tachyonic instability of the open bosonic string is analyzed using the level truncation approach to string field theory. We have calculated all terms in the cubic action of the string field… Expand

Type IIA Moduli Stabilization
- A. U.S.
- 2005
We demonstrate that flux compactifications of type IIA string theory can classically stabilize all geometric moduli. For a particular orientifold background, we explicitly construct an infinite… Expand

Multiple Dp-branes in Weak Background Fields
- A. U.S.
- 1999
We find the terms in the nonabelian world-volume action of a system of many Dp-branes which describe the leading coupling to all type II supergravity background fields. These results are found by… Expand

Estimators of Fractal Dimension : Assessing the Roughness of Time Series and Spatial Data
- A. U.S.
- 2010
Abstract The fractal or Hausdorff dimension is a measure of roughness (or smoothness) for time series and spatial data. The graph of a smooth, differentiable surface indexed in Rd has topological and… Expand

Curved Mesh Generation and Mesh Refinement using Lagrangian Solid Mechanics
- A. U.S.
- 2009
We propose a method for generating well-shaped curved unstructured meshes using a nonlinear elasticity analogy. The geometry of the domain to be meshed is represented as an elastic solid. The… Expand
