A Feasibility Study of Sea Ice Motion and Deformation Measurements Using Multi-Sensor High-Resolution Optical Satellite Images

open access: yesRemote Sensing, 2017
Sea ice motion and deformation have generally been measured using low-resolution passive microwave or mid-resolution radar remote sensing datasets of daily (or few days) intervals to monitor long-term trends over a wide polar area. This feasibility study

Resolutional Analysis of Multiplicative High-Frequency Speckle Noise Based on SAR Spatial De-Speckling Filter Implementation and Selection

open access: yesRemote Sensing, 2019
Due to the inherent characteristics of the electromagnetic wave scattering phenomenon, synthetic aperture radar (SAR) images are directly degraded by high-frequency multiplicative speckle (HMS) noise, which makes image de-speckling filter application and

Residual prediction based on unit selection [PDF]

open access: yesIEEE Workshop on Automatic Speech Recognition and Understanding, 2005., 2005
Recently, we presented a study on residual prediction techniques that can be applied to voice conversion based on linear transformation or hidden Markov model-based speech synthesis. Our voice conversion experiments showed that none of the six compared techniques was capable of successfully converting the voice while achieving a fair speech quality. In

Multifractal Scaling of Thermally-Activated Rupture Processes

open access: yes, 2004
We propose a ``multifractal stress activation'' model combining thermally activated rupture and long memory stress relaxation, which predicts that seismic decay rates after mainshocks follow the Omori law $\sim 1/t^p$ with exponents $p$ linearly ...

Early pH change predicts intensive care unit mortality

open access: yesIndian Journal of Critical Care Medicine, 2018
Metabolic acidosis is associated with increased mortality in critically ill patients. We hypothesized that early correction of acidosis of presumed metabolic origin results in improved outcomes.We conducted a prospective, observational study from February 2015 to June 2016 in a 12 bed mixed intensive care unit (ICU) of a 1000 bed tertiary care hospital

Online Unit Profit Knapsack with Predictions

open access: yesAlgorithmica
AbstractA variant of the online knapsack problem is considered in the setting of predictions. In Unit Profit Knapsack, the items have unit profit, i.e., the goal is to pack as many items as possible. For Online Unit Profit Knapsack, the competitive ratio is unbounded.
