Influences on flood frequency distributions in Irish river catchments [PDF]

Hydrology and Earth System Sciences, 2012
This study explores influences on flood frequency distributions in Irish rivers. A Generalised Extreme Value (GEV) type I distribution is recommended in Ireland for estimating flood quantiles in a single site flood frequency analysis. This paper presents

Imputing stem frequency distributions using harvester and airborne laser scanner data: a comparison of inventory approaches

Silva Fennica, 2023
Stem frequency distributions provide useful information for pre-harvest planning. We compared four inventory approaches for imputing stem frequency distributions using harvester data as reference data and predictor variables computed from airborne laser ...

Frequency Analysis of Extreme Events Using the Univariate Beta Family Probability Distributions

Applied Sciences, 2023
This manuscript presents three families of distributions, namely the Beta, Beta Prime and Beta Exponential families of distributions. From all the distributions of these families, 14 statistical distributions of three, four and five parameters are ...

The Apparent Constant-Phase-Element Behavior of a Disk Electrode with Faradaic Reactions [PDF]

, 2007
Geometry-induced current and potential distributions modify the global impedance response of a disk electrode subject to faradaic reactions. The problem was treated for both linear and Tafel kinetic regimes.

Robust Time-Frequency Distributions with Complex-Lag Argument

EURASIP Journal on Advances in Signal Processing, 2010
The robust time-frequency distributions with complex-lag argument are proposed. They can provide an accurate estimation of fast varying instantaneous frequency in the presence of noise with heavy-tailed probability density function.

Power-Law Statistics Of Driven Reconnection In The Magnetically Closed Corona

, 2018
Numerous observations have revealed that power-law distributions are ubiquitous in energetic solar processes. Hard X-rays, soft X-rays, extreme ultraviolet radiation, and radio waves all display power-law frequency distributions.

Geometry of River Networks II: Distributions of Component Size and Number [PDF]

, 2000
The structure of a river network may be seen as a discrete set of nested sub-networks built out of individual stream segments. These network components are assigned an integral stream order via a hierarchical and discrete ordering method.

On the Relation between Wind Speed and Maximum or Mean Water Wave Height

Atmosphere
Dimensional analysis shows that the relation between wind speed and maximum or mean water wave height takes the form H=cU02g, where H is the maximum or mean water wave height caused by wind of speed U0, g is the gravitational acceleration, and c is a ...

Computationally Efficient Scale Covariant Time-Frequency Distributions

EURASIP Journal on Advances in Signal Processing, 2009
Scale is a physical attribute of a signal which occurs in many natural settings. Time-frequency distributions (TFDs) belonging to Cohen's class are invariant to time and frequency shifts, but are not necessarily covariant to the time scalings of the ...

Finite-sample frequency distributions originating from an equiprobability distribution

, 2002
Given an equidistribution for probabilities p(i)=1/N, i=1..N. What is the expected corresponding rank ordered frequency distribution f(i), i=1..N, if an ensemble of M events is drawn?Comment: 4 pages, 4 ...
