Adaptive Discontinuous Galerkin Finite Element Methods for Compressible Fluid Flows
 SIAM J. Sci. Comput
"... this paper is to discuss the a posteriori error analysis and adaptive mesh design for discontinuous Galerkin finite element approximations to systems of conservation laws. In Section 2, we introduce the model problem and formulate its discontinuous Galerkin finite element approximation. Section 3 is ..."

polyhedral domain fl in lI n, n _> 1, with boundary 0fl, we consider the following problem: find u: fl > lI m, m _> 1, such that div(u) = 0 in , (2.1) where, ,: m __> mxn is continuously differentiable. We assume that the system of conservation laws (2.1) may be supplemented by appropriate
A New Approximate Maximal Margin Classification Algorithm
 JOURNAL OF MACHINE LEARNING RESEARCH
, 2001
"... A new incremental learning algorithm is described which approximates the maximal margin hyperplane w.r.t. norm p 2 for a set of linearly separable data. Our algorithm, called alma p (Approximate Large Margin algorithm w.r.t. norm p), takes O (p 1) 2 2 corrections to separate the data wi ..."

experiments on both realworld and artificial datasets. We compared alma 2 (i.e., alma p with p = 2) to standard Support vector Machines (SVM) and to two incremental algorithms: the Perceptron algorithm and Li and Long's ROMMA. The accuracy levels achieved by alma 2 are superior to those achieved
Quasiphasematched second harmonic generation of blue light in periodically poled LiNbO
 Appl. Phys. Lett
, 1990
"... AbstractQuasiphase matching is a technique for phase matching nonlinear optical interactions in which the relative phase is corrected at regular intervals using a structural periodicity built into the nonlinear medium. The theory of quasiphasematched second harmonic generation is presented in b ..."

The numpy array: a structure for efficient numerical computation
 Computing in Science & Engineering
, 2011
"... the published version if accessible, as it contains editor’s improvements. (c) 2011 IEEE.∗ In the Python world, NumPy arrays are the standard representation for numerical data. Here, we show how these arrays enable efficient implementation of numerical computations in a highlevel language. Overal ..."

. Overall, three techniques are applied to improve performance: vectorizing calculations, avoiding copying data in memory, and minimizing operation counts. We first present the NumPy array structure, then show how to use it for efficient computation, and finally how to share array data with other libraries.

"... Abstract. This paper presents the Cholesky factor–alternating direction implicit (CF–ADI) algorithm, which generates a lowrank approximation to the solution X of the Lyapunov equation AX + XAT = −BBT. The coefficient matrix A is assumed to be large, and the rank of the righthand side −BBT is assu ..."

is assumed to be much smaller than the size of A. The CF–ADI algorithm requires only matrixvector products and matrixvector solves by shifts of A. Hence, it enables one to take advantage of any sparsity or structure in A. This paper also discusses the approximation of the dominant invariant subspace
Local systems of twisted vertex operators, vertex superalgebras and twisted modules
 Contemporary Math
"... Abstract. We introduce the notion of “local system of ZTtwisted vertex operators ” on a Z2graded vector space M, generalizing the notion of local system of vertex operators [Li]. First, we prove that any local system of ZTtwisted vertex operators on M has a vertex superalgebra structure with an a ..."
