Mitigation of the Effects of Unknown Sea Clutter Statistics by Using Radial Basis Function Network [PDF]

open access: yesRadioengineering, 2020
In this paper, we investigate feasibility of employing Radial Basis Function (RBF) network into non-coherent detection process, for detection of targets embedded in sea clutter of unknown statistics. We particularly have in mind Croatian part of Adriatic

Lognormal Lorenz and normal receiver operating characteristic curves as mirror images [PDF]

open access: yesRoyal Society Open Science, 2015
The Lorenz curve for assessing economic inequality depicts the relation between two cumulative distribution functions (CDFs), one for the distribution of incomes or wealth and the other for their first-moment distribution.

Parametric modelling of cost data: some simulation evidence [PDF]

open access: yes, 2005
Recently, commentators have suggested that the distributional form of cost data should be explicitly modelled to gain efficiency in estimating the population mean.

Fitting the Modified-Power-Lognormal to the Sum of Independent Lognormals Distribution [PDF]

open access: yesGLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009
We propose a new method for calculating a tight approximation to the distribution of the sum of independent lognormal random variables. We make use of a three-parameter modified-power-lognormal distribution function as the approximating distribution.

Lognormal firing rate distribution reveals prominent fluctuation–driven regime in spinal motor networks

open access: yeseLife, 2016
When spinal circuits generate rhythmic movements it is important that the neuronal activity remains within stable bounds to avoid saturation and to preserve responsiveness. Here, we simultaneously record from hundreds of neurons in lumbar spinal circuits

The Evolution of Optical Depth in the Ly-alpha Forest: Evidence Against Reionization at z~6 [PDF]

open access: yes, 2006
We examine the evolution of the IGM Ly-alpha optical depth distribution using the transmitted flux probability distribution function (PDF) in a sample of 63 QSOs spanning absorption redshifts 1.7 < z < 5.8.

Firm size and economic concentration: An analysis from a lognormal expansion.

open access: yesPLoS ONE, 2021
This paper studies the distribution of the firm size for the Colombian economy showing evidence against the Gibrat's law, which assumes a stable lognormal distribution.

Neuronal Population Activity in Spinal Motor Circuits: Greater Than the Sum of Its Parts

open access: yesFrontiers in Neural Circuits, 2017
The core elements of stereotypical movements such as locomotion, scratching and breathing are generated by networks in the lower brainstem and the spinal cord.

A dynamical Gaussian, lognormal, and reverse lognormal Kalman filter

open access: yesQuarterly Journal of the Royal Meteorological Society, 2023
AbstractWe derive a generalization of the Kalman filter that allows for non‐Gaussian background and observation errors. The Gaussian assumption is replaced by considering that the errors come from a mixed distribution of Gaussian, lognormal, and reverse lognormal random variables.
