The estimation of groundwater recharge by soil water balance in semi-arid regions

open access: yes, 2002
Quantification of groundwater recharge is a crucial prerequisite for sustainable groundwater resource management, particularly in semi-arid areas where there are large demands for groundwater supplies. This research presents an alternative approach for

Semi-Empirical Model and Experimental Verification of Scroll Compressor with Vapor Injection

open access: yesZhileng xuebao
To simulate and optimize an enhanced vapor-injection system, it is necessary to develop a vapor-injection scroll compressor model with fast calculation speed, high accuracy, good extrapolation accuracy, and few parameters for computation.

Semi-parametric Models for Satisfaction with Income

open access: yes
An overview is presented of some parametric and semi-parametric models, estimators, and specification tests that can be used to analyze ordered response variables.In particular, limited dependent variable models that generalize or-dered probit are ...

AN EMPIRICAL BAYES APPROACH TO MODELING DROUGHT

open access: yes
This paper illustrates an alternative approach to estimating the occurrence of drought. The empirical Bayes methodology was developed because of deficiencies in time-series and regression analysis with respect to prediction of drought. This manuscript is

Semi-blind image restoration based on Chan-Vese denoising model

open access: yes, 2008
A semi-blind image restoration algorithm is proposed based on reduced non-convex approximation of Luminita Vese and Tony Chan's(C-V)denoising model.Compared with C-V denoising model,we modify the fidelity term and add a term on point spread function ...
