Abstract During last decades, anthropogenic underwater sound and its chronic impact on marine species have been recognised as an environmental protection challenge. At the same time, studies on the spatial and temporal variability of ambient sound, a

Absolutely continuous copulas with prescribed support constructed by differential equations, with an application in toxicology
Autor: Niklas Brännström, Leif Persson, Oscar Björnham
A new method for constructing absolutely continuous two--dimensional copulas by differential equations is presented. The copulas are symmetric with respect to reflection in the opposite diagonal. The support of the copula density may be prescribed to

Autor: Leif Persson, Christian Ekberg, M. Bruggeman, Henrik Ramebäck, Anna Vesterlund
Publikováno v: Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 178
In this study, calculation of decision threshold and detection limit expressed in counts for low-level radioactivity measurements were evaluated and compared to a Monte Carlo method for the case of paired Poisson-distributed observations, i.e. for di

Variations of b-values preceding large earthquakes in the shallow subduction zones of Cocos and Nazca plates
Autor: Ota Kulhánek, Paiboon Nuannin, Leif Persson
Publikováno v: Journal of South American Earth Sciences. 82:207-214
The potential of b-value variations as a medium-term (months, years) precursor was investigated by focusing on the eight largest earthquakes, Mw ≥ 7.0, occurring between January 2000 and April 2010 in the shallow subduction zones of Cocos and Nazca

Calculation of decision threshold and detection limit in radiometric measurements using a Monte Carlo Method
Autor: Petter Lindgren, Christian Ekberg, Henrik Ramebäck, Leif Persson, M. Bruggeman
Publikováno v: Applied radiation and isotopes : including data, instrumentation and methods for use in agriculture, industry and medicine. 156
Calculation of the decision threshold and detection limit of a measurement, or measurement method, are crucial in order to decide if an analyte is present or not and with what confidence it can be quantified. That decision is important in view of pos

A generic emission model to predict release of organic substances from materials in consumer goods
Autor: Leif Persson, Tomas Holmgren, Peter Haglund, Patrik L. Andersson
Publikováno v: Science of The Total Environment. 437:306-314
Organic chemicals may be released when consumer goods are used, contributing to environmental and human levels of potentially hazardous chemicals. A generic model was developed to predict emissions of organic chemicals from various materials in consu

Spatial and temporal characteristics of aftershocks of the December 26, 2004 and March 28, 2005 earthquakes off NW Sumatra
Autor: Ota Kulhánek, Paiboon Nuannin, Leif Persson
Publikováno v: Journal of Asian Earth Sciences. 46:150-160
Two aftershock series following the December 26, 2004 ( M w = 9.0) and the March 28, 2005 ( M w = 8.6) earthquakes off coast of NW Sumatra are studied. Deduced space heterogeneity of b -values, in the Gutenberg–Richter formula, and p -values, in th
