Photovoltaic conversion at reduced dimensions

Physica E: Low-dimensional Systems and Nanostructures, 2002
Abstract Reducing the geometric dimensionality in a photovoltaic cell is useful in designing optimal contact geometry, in enhancing the conversion efficiency by enlarging the concentrations of photogenerated carriers and, generally, by utilizing thin-film structures for solar cells.

REDUCED-DIMENSION CONTROL REGRESSION [PDF]

, 2006
A model to investigate the relationship between one variable and another usually requires controls for numerous other effects which are not constant across the sample; where the model omits some elements of the true process, estimates of parameters of interest will typically be inconsistent.

Reduced dimension quadratic detection algorithms

SPIE Proceedings, 2000
Hyperspectral images may be collected in tens to hundreds of spectral bands having band widths on the order of 1-10 nanometers. Principal component (PC), maximum-noise-fraction (MNF), and vector quantization (VQ) transforms are used for dimension reduction and subspace selection.

How to Reduce Dimension while Improving Performance

2012
This paper addresses the feature subset selection for an automatic Arabic speaker recognition system. An effective algorithm based on genetic algorithm is proposed for discovering the best feature combinations using feature reduction and recognition error rate as performance measure. Experimentation is carried out using QSDAS corpora.

Reducing Dimensions in a Large TVP-VAR

SSRN Electronic Journal, 2018
This paper proposes a new approach to estimating high dimensional time varying parameter structural vector autoregressive models (TVP-SVARs) by taking advantage of an empirical feature of TVP-(S)VARs. TVP-(S)VAR models are rarely used with more than 4-5 variables.
