We investigate the feasibility to align synthetic aperture radar (SAR) imagery based on a compensation for sea ice drift occurring between temporally shifted image acquisitions. The alignment is requirement improving classification by combining multi-frequency SAR images acquired at different times. Images obtained frequencies provide complementary information, thus reducing ambiguities in sepa...

Following the suppression of recombination, gene expression levels decline on the sex-limited chromosome, and this can lead to selection for dosage compensation in the heterogametic sex to rebalance average expression from the X or Z chromosome with average autosomal expression. At the same time, due to their unequal pattern of inheritance in males and females, the sex chromosomes are subject t...

We investigate a digital back-propagation simplification method to enable computationally-efficient digital nonlinearity compensation for a coherently-detected 112 Gb/s polarization multiplexed quadrature phase shifted keying transmission over a 1,600 km link (20 x 80 km) with no inline compensation. Through numerical simulation, we report up to 80% reduction in required back-propagation steps ...

A new region-based coding scheme is introduced. It uses generalized parabolic blending curves for contour coding which lead to visually preferable smooth contours and support good local controllability. A rate-distortion criterion is applied to decide which regions should be used for motion compensation and for optimizing the region contours. The conditions for optimal regions in a rate-distort...

In this study, an image backlight compensation method using adaptive luminance modification is proposed for efficiently obtaining clear images.The proposed method combines the fuzzy C-means clustering method, a recurrent functional neural fuzzy network (RFNFN), and a modified differential evolution.The proposed RFNFN is based on the two backlight factors that can accurately detect the compensat...

I propose a simple model with complete and perfect information that analyzes the relation between managerial incentive compensation and the firm’s choice between public and bank debt. My analysis of firm-level data over the period 1992-2005 offers considerable support to the predictions of the model. I find a positive relation between the level of incentive compensation and the preference for b...
