Small area estimation methods are used in surveys, where sample sizes too small to get reliable direct estimates of parameters some population domains. We consider design-based linear combinations and synthetic estimators propose a two-step procedure approach the optimal combination. construct mean square error estimator suitable for this any other composition that one. apply theory two composi...

Estimating a joint Highest Posterior Density credible set for multivariate posterior density is challenging as dimension gets larger. Credible intervals univariate marginals are usually presented ease of computation and visualisation. There often two layers approximation, we may need to compute target which itself only an approximation the true density. We obtain sets estimation trees given by ...

this paper presents a new observer design methodology for a time varying actuator fault estimation. a new linear matrix inequality (lmi) design algorithm is developed to tackle the limitations (e.g. equality constraint and robustness problems) of the well known so called fast adaptive fault estimation observer (fafe). the fafe is capable of estimating a wide range of time-varying actuator fault...

introduction: scattered photon is one of the main defects that degrade the quality and quantitative accuracy of nuclear medicine images. accurate estimation of scatter in projection data of spect is computationally extremely demanding for activity distribution in uniform and non-uniform dense media. methods: the objective of this paper is to develop and validate a scatter correction technique t...

long-term settlement of msw landfills is a complex process, which is explained by the following two mechanisms: (1) the mechanical long-term compression of degradable organic solids (dos) and un-degradable organic solids (udos); and (2) the decomposition-based compression of the dos. based on these two distinct settlement mechanisms, in this study, the authors propose a new estimation model to ...

the purpose of this study is to identify the effect of ordinary kriging (ok) and inverse distance weighted (idw) estimation methods for the delineation of mineralized zones based on subsurface data using concentration–volume (c–v) multifractal modeling in the dardevey iron ore deposit, ne iran. variograms and anisotropic ellipsoid were generated for the fe distribution by the above estimation m...
