Horvitz-thompson estimator of population mean under inverse sampling designs
(
Iranian Mathematical Society
, 2012 , Article)
Inverse sampling design is generally considered to be an appropriate technique when the population is divided into two subpopulations, one of which contains only a few units. Here, we de- rive the Horvitz-Thompson estimator ...
Confidence intervals for quantiles using record values from the generalized exponential distribution
(
Nova Science Publishers, Inc.
, 2012 , Book chapter)
Likelihood-based and bootstrap confidence intervals for the quantiles of the generalized exponential distribution based on record values are developed. Intervals for the difference of quantiles based on two independent ...
Mangrove-bearing limestone from the Eocene Dammam Formation, Arabian Gulf: Implications for the mangrove dispersal controversy
(
springer link
, 2012 , Article)
Fossil mangrove remains are found within the shallow carbonate strata of the Middle Eocene Dammam Formation of the Arabian Gulf. This formation is of wide distribution across most eastern parts of the Arabian Platform and ...
Standing stocks and body size of deep-sea macrofauna: Predicting the baseline of 2010 Deepwater Horizon oil spill in the northern Gulf of Mexico
(
Elsevier
, 2012 , Article)
A composite database encompassing 6 benthic surveys from years 1983 to 2003 was constructed to evaluate the distribution of macrofaunal biomass in the deep Gulf of Mexico (GoM) prior to the Deepwater Horizon oil spill. ...
Infinite-dimensional LQ optimal control of a dimethyl ether (DME) catalytic distillation column
(
Elsevier
, 2012 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator in order to control the concentration profiles along a catalytic distillation column, which is modelled by a set of coupled hyperbolic partial ...
Extracellular matrix (ECM)
(
Springer Netherlands
, 2012 , Book chapter)
Summary: The region of space at the periphery of cyanobacterial cells is the interface between the environment and intracellular processes. This metaspace may include a structure appressed to the outer wall and membrane, ...
Isolation of entomopathogenic Bacillus from a biodynamic olive farm and their pathogenicity to lepidopteran and coleopteran insect pests
(
Elsevier Ltd
, 2012 , Article)
The occurrence of Bacillus entomopathogenic bacteria on a Tunisian biodynamic farm was determined by examining 75 samples from olive tree (Olea europaea L.) habitats. A total of 40 Bacillus isolates were characterized ...
Synthesis, spectroscopic and thermal studies of charge-transfer molecular complexes formed in the reaction of 1,4-bis (3-aminopropyl) piperazine with σ- and π acceptors
(
Elsevier
, 2012 , Article)
Abstract In the present study, solid charge-transfer (CT) molecular complexes formed in the reaction of the electron donor 1,4-bis (3-aminopropyl) piperazine (APPIP) with the σ-electron acceptor iodine and π-acceptors ...
