Estimating Fuel Loads and Structural Characteristics of Shrub Communities by Using Terrestrial Laser Scanning

open access: yesRemote Sensing, 2020
Forest fuel loads and structural characteristics strongly affect fire behavior, regulating the rate of spread, fireline intensity, and flame length. Accurate fuel characterization, including disaggregation of the fuel load by size classes, is therefore ...

Simultant: simultaneous curve fitting of functions and differential equations using analytical gradient calculations

open access: yesBMC Bioinformatics, 2022
Background The initial step in comparing mathematical models to experimental data is to do a fit. This process can be complicated when either the mathematical models are not analytically solvable (e.g. because of nonlinear differential equations) or when

Temperature Measurements by Wavelength Modulation Diode Laser Absorption Spectroscopy with Logarithmic Conversion and 1f Signal Detection

open access: yesSensors, 2023
A new version of a sensor for temperature measurements in the case of strong laser intensity fluctuation was developed. It was based on tunable diode laser absorption spectroscopy (TDLAS) with wavelength modulation, logarithmic conversion of the ...

Improved Measurements of the IXPE Crab Polarization

open access: yesThe Astrophysical Journal, 2023
X-ray polarization from the Imaging X-ray Polarimetry Explorer (IXPE) provides an important new probe of the geometry of the pulsar emission zone and of particle acceleration in the surrounding pulsar wind nebula.

Evaluation of peak-fitting software for magnesium quantification through k0-instrumental neutron activation analysis

open access: yesNuclear Engineering and Technology, 2022
The selection and effective utilization of peak-fitting software for conventional gamma-ray spectrum analysis is significant for accurate determination of the mass fraction of elements, particularly in complex peak regions.

Environmental effects on the genetic architecture of fitness components in a simultaneous hermaphrodite

open access: yesJournal of Animal Ecology, 2021
Abstract Understanding how environmental change affects genetic variances and covariances of reproductive traits is key to formulate firm predictions on evolutionary responses. This is particularly true for sex‐specific variance in reproductive success, which has been argued to affect how populations can adapt to environmental change.

Modelo dinámico de crecimiento de bosques de Picea abies (L.) Karst. enAlemania

open access: yesRecursos Rurais, 2014
In the present study a dynamic stand growth model for Norway spruce (Picea abies (L.) Karst.) forests was developed from data of 99 research plots, which had been measured between one and seventeen times in northwestern and southern Germany.
