OPTIMAL BEAM PATTERN DESIGN FOR VERY LARGE SENSOR ARRAYS WITH SPARSE SAMPLING
OPTIMAL BEAM PATTERN DESIGN VERY LARGE SENSOR ARRAYS SPARSE SAMPLING
2015/9/29
Consider a large scale sensor array having N sensors that monitors a surveillance area. Using all sensors simultaneously may be unreasonable in terms of power consumption and data processing.For examp...
BROADBAND SENSOR LOCATION SELECTION USING CONVEX OPTIMIZATION IN VERY LARGE SCALE ARRAYS
array processing multi-frequency beam pattern design sensor location selection very large scale arrays convex optimization simulated annealing
2015/9/29
Consider a sensing system using a large number of N microphones placed in multiple dimensions to monitor a broadband acoustic field. Using all the microphones at once is impractical because of the amo...
Imputing Missing Data for Gene Expression Arrays
Imputing Missing Data Gene Expression Arrays
2015/8/21
Here we describe three different methods for imputation.The first is based on a reduced rank SVD of the expression matrix, the second is based on K-nearest neighbor averaging, and the third is based o...
Efficient Quadratic Regularization for Expression Arrays

2015/8/21
Gene expression arrays typically have 50 to 100 samples and 1,000 to 20,000 variables (genes).There have been many attempts to adapt statistical models for regression and classification to these data,...
Bootstrapping data arrays of arbitrary order
Bayesian pigeonhole bootstrap online bagging online bootstrap
2015/8/21
In this paper we study a bootstrap strategy for estimating the variance of a mean taken over large multifactor crossed random e ects data
sets. We apply bootstrap reweighting independently to the lev...

mixed-level orthogonal arrays generalized Kronecker product
2015/3/18
in this paper, we propose a new general approach to construct asymmetrical orthogonal arrays, namely generalized Kronecker product. The
operation is not usual Kronecker product in the theory of matri...
AN ALGORITHMIC APPROACH TO CONSTRUCTING ORTHOGONAL AND NEAR-ORTHOGONAL ARRAYS
CONSTRUCTING ORTHOGONAL NEAR-ORTHOGONAL ARRAYS
2015/3/18
Due to run size constraints, near-orthogonal arrays (near-OAs) and sup ersaturated designs, a sp ecial case of near-OA, are considered go o d alternatives to OAs.
This pap er shows (i) a combinatoria...
Orthogonal Arrays of Strength 3 with Full Estimation Capacities
Experimental Design Non-isomorphic Designs
2015/3/18
Orthogonal arrays of strength 3 permit estimation of all the main effects of the experimental factors free from contamination with 2-factor
interactions (2fi). If they allow for estimation of all the...
Dynamical light control in longitudinally modulated segmented waveguide arrays

2011/7/7
We address light propagation in segmented waveguide arrays where the refractive index is longitudinally modulated with an out-of-phase modulation in adjacent waveguides, so that the coupling strength ...
Central limit theorem for triangular arrays of Non-Homogeneous Markov chains

2011/3/1
In this paper we obtain the central limit theorem for triangular arrays of non-homogeneous Markov chains under a condition imposed to the maximal coefficient of correlation. The proofs are based on ma...
Applications of operational calculus: Equations for rectangular arrays of four and five data
Interpolation shifting operator rectangular data array operational equations
2010/11/1
Selections of equations for four or five data in rectangular array are seldom encountered in textbooks. New methods illustrate polynomial and exponential equations for the two designs. The methods are...

Splitting broad beams arrays dissipative spatial solitons material virtual gratings
2010/11/10
We elaborate two generic methods for producing two-dimensional (2D) spatial soliton arrays (SSAs) in the framework of the cubic-quintic (CQ) complex Ginzburg-Landau (CGL) model. The first approach de...
