Error resilience analysis of wireless image transmission using JPEG, JPEG 2000 and JPWL [PDF]

open access: yes, 2009
The wireless extension of the JPEG 2000 standard formally known as JPWL is the newest international standard for still image compression. Different from all previous standards, this new standard was created specifically for wireless imaging applications.

Standard Error as Standard? [PDF]

open access: yesCirculation, 2003
To the Editor: I am concerned about errors in simple statistical concepts in articles recently published in Circulation . First, I worry about the widespread use of the standard error of mean (SEM) to describe the variability of numerical data. Specifically, SEM was used in 30% of the clinical investigations and reports and in 76% of the basic science

A review of effect sizes and their confidence intervals, Part {I}: The Cohen's d family [PDF]

open access: yesTutorials in Quantitative Methods for Psychology, 2018
Effect sizes and confidence intervals are important statistics to assess the magnitude and the precision of an effect. The various standardized effect sizes can be grouped in three categories depending on the experimental design: measures of the ...

ENO-wavelet transforms for piecewise smooth functions [PDF]

open access: yes, 2002
We have designed an adaptive essentially nonoscillatory (ENO)-wavelet transform for approximating discontinuous functions without oscillations near the discontinuities. Our approach is to apply the main idea from ENO schemes for numerical shock capturing

Analysis of lnterdependence Between Air Transfer of LC-ltems and Geographical Distances

open access: yesPromet (Zagreb), 2012
Using the data collected by the Universal Postal Union, thepaper studies the con·elation between the delive1y time of ordinarymail items by air and the geographical distance. lt is foundthat there is poor linear co"elation.

Joint processing of measurements in a rangefinder-doppler multistatic radar system

open access: yesНаучный вестник МГТУ ГА, 2020
The article considers the option of organizing joint processing of radar information in a multistatic rangefinder - doppler radar system. The least-squares method is used to obtain analytical expressions for oblique ranges and radial velocities of ...

Wide-Range Digital-Analog Mixed Calibration Technology of a DC Instrument Transformer Test Set

open access: yesIEEE Access, 2021
A DC instrument transformer test set (ITTS), as an error measurement device for DC instrument transformers, needs to be calibrated regularly to ensure its accuracy. Existing calibration technology can only achieve DC ITTS error calibrations within a zero
