A comprehensive assessment of policy impact on greenhouse gas (GHG) emissions from agricultural soils requires careful consideration of both socio-economic aspects and the environmental heterogeneity ...
Procedure to estimate maximum ground acceleration from macroseismic intensity rating: application to the Lima,Perú data from the October-3-1974-8.1-Mw earthquake
maximum ground acceleration macroseismic intensity rating 8.1-Mw earthquake

Post-disaster reconstruction management of urban areas requires timely information on the ground response microzonation to strong levels of ground shaking to minimize the rebuilt-environment vulnerabi...
Estimate of the $L^p$-Fourier Transform Norm on Strong *-Regular Exponential Solvable Lie Groups
Exponential Lie group Plancherel measure unitary representation coadjoint orbit $L^p$-Fourier transform
2007/12/13
We study the $L^{p}$-Fourier transform for a special class of exponential Lie groups, the strong $\ast$-regular exponential Lie groups. Moreover, we provide an estimate of its norm using the orbit met...
Asymptotic Properties of the Maximum Likelihood Estimate in Generalized Linear Models with Stochastic Regressors
Generalized linear models Consistency Asymptotic normality
2007/12/12
For generalized linear models (GLM), in case the regressors are stochastic and have different distributions, the asymptotic properties of the maximum likelihood estimate (MLE) $\hat{\beta}_n$ of the p...
Quadratic Admissible Estimate of Covariance in Pseudo-Elliptical Contoured Distribution
Admissibility covariance quadratic estimator quadratic loss function
2007/12/11
This article mainly discusses the admissibility of quadratic estimate of covariance in pseudo-elliptical distribution. Under the quadratic loss function, the necessary and sufficient conditions that a...
Comparison of MINQUE and Simple Estimate of the Error Variance in the General Linear Models
general linear model MINQUE mean square error
2007/12/11
Comparison is made between the MINQUE and simple estimate of the error variance in the normal linear model under the mean square errors criterion, where the model matrix need not have full rank and th...
Delete-group Jackknife Estimate in Partially Linear Regression Models with Heteroscedasticity
partially linear regression model asymptotic variance
2007/12/10
Consider a partially linear regression model with an unknown vector parameter β, an unknown function g(·), and unknown heteroscedastic error variances. Chen, You~([23]) proposed a semiparametric gener...
Using in-situ temperature measurements to estimate saturated soil thermal properties by solving a sequence of optimization problems

AN IMPROVEMENT ON ESTIMATE OF d_0/d~* FOR STARLIKE FUNCTIONS
Starlike function radius of convexity
2007/8/7
Let S~* be the class of starlike functions in unit disc. For f∈S~*, denote its radius of convexity by r_0 and let d_0=\[min_}{\|z\|=r_0}\]|f(z)|, d~*=inf{|β||f(z)≠β,|z|<1}. In this paper we prove d_0/...
