The ICAO Second Order Step threat model defines a class of signal deformations that present a potential integrity threat to GPS-based aircraft landing systems such as the Local Area Augmentation...
Land Surface Temperature (LST) is an important parameter in the land surface processes on regional and global scale. The Land Surface Temperature Diurnal (LSTD) cycle of different land cover is an exc...
In this paper we describe a general procedure for calculating synthetic sensor radiances from variable output from a global atmospheric forecast model.
We have studied the curvaton scenario in brane world cosmology in an intermediate inflationary scenario. This approach has allowed us to find some constraints on different parameters that appear in th...

Background and Aims: Prediction of phenotypic traits from new genotypes under untested environmental conditions is crucial to build simulations of breeding strategies to improve target traits. Althou...
The Icosahedral Shallow Water Model (ICOSWM) has been a first step in the development of the ICON (acronym for ICOsahedral Nonhydrostatic) models. ICON is a joint project of the Max Planck Institute f...
构建了遗传算法与Levenberg-Marquardt算法相结合的混合遗传算法,用于求解根系吸水模型参数。分别进行数值试验和棉花根系吸水试验对混合遗传算法求解精度进行验证。数值试验表明,采用混合遗传算法优化求解根系吸水模型参数的优化值具有较高的精度,含水率资料的时间步长和空间步长对根系吸水模型参数的优化精度有较大影响,在实际中时间步长可取值5~10d,空间步长取值5~10cm。对室内棉花根系吸水进...
A time domain method to precisely estimate the sinusoidal model parameters of cochannel speech is presented. The method does not require the calculation of the Fourier transform nor the multiplication...
Data scarcity and model over-parameterisation, leading to model equifinality and large prediction uncertainty, are common barriers to effective hydrological modelling. The problem can be alleviated b...
In this study we examine the relative performance of a range of methods for transposing catchment model parameters to ungauged catchments. We calibrate 11 parameters of a semi-distributed conceptual r...
The parameters of hydrological models for catchments with few or no discharge records can be estimated using regional information. One can assume that catchments with similar characteristics show a si...
In this study, land surface related parameter distributions of a conceptual semi-distributed hydrological model are constrained by employing time series of satellite-based evaporation estimates during...
The estimation of hydrological model parameters is a challenging task. With increasing capacity of computational power several complex optimization algorithms have emerged, but none of the algorithms ...
We have been collecting biological data for the construction of a food web model of Calabash Caye, Belize using Ecopath with Ecosim software. Characterization of the mangrove, seagrass and coral reef...
