ESTIMATION OF AERODYNAMIC ROUGHNESS AND ZERO PLANE DISPLACEMENT USING MEDIUM DENSITY OF AIRBORNE LIDAR DATA
Airborne LiDAR Aerodynamic Roughness Length Zero Plane Displacement Forest
2016/10/14
This paper presents a framework to estimate aerodynamic roughness over specific height (zo/H) and zero plane displacement (d/H) over various landscapes in Kelantan State using airborne LiDAR data. The...
ESTIMATION OF CO- AND POSTSEISMIC DEFORMATION AFTER THE Mw 8.6 NIAS-SEMEULUE AND Mw 8.5 BENGKULU EARTHQUAKES FROM CONTINUOUS GPS DATA
GPS earthquake postseismic deformation
2016/10/14
The Mw 8.5 Bengkulu earthquake of 30 September 2007 and the Mw8.6 28 March 2005 are considered amongst large earthquake ever recorded in Southeast Asia. The impact into tectonic deformation was record...

Korea Peninsular Tohoku-Oki earthquake postseismic deformation
2016/10/14
This paper describes utilization of GPS data in Korea Peninsula and IEODO ocean research station for investigation of postseismic deformation characteristic after the 2011 Tohoku-oki Mw9.0 Earthquake....
Estimation of the dietary requirement for vitamin D in adolescents aged 14–18 y: a dose-response, double-blind, randomized placebo-controlled trial
adolescents dose-response randomized controlled trial recommendations requirements vitamin D
2018/12/18
Background: Adolescents are a population group at high risk of low vitamin D status, yet the evidence base for establishing dietary vitamin D requirements remains weak.
Estimation of Genetic Parameters for First Lactation Monthly Test-day Milk Yields using Random Regression Test Day Model in Karan Fries Cattle
Test-day Milk Yield Random Regression Model Heritability Genetic Correlation Karan Fries Cattle
2016/7/27
A single trait linear mixed random regression test-day model was applied for the first time for analyzing the first lactation monthly test-day milk yield records in Karan Fries cattle. The test-day mi...
Estimation of methanogenesis by quantification of coenzyme F430 in marine sediments
methane hydrate methanogens function-specific compound analysis marine sedimen
2017/4/10
Coenzyme F430 is the hydrocorphinoid nickel complex which acts as active site in methyl-coenzyme M reductase
(MCR). The MCR-F430 complex catalyzes the last step of methanogenesis: reduction of methyl...
Nonparametric and Semiparametric Regressions Subject to Monotonicity Constraints: Estimation and Forecasting
Nonlinearity Nonparametric regression Semiparametric regression Local mono- tonicity Bagging
2016/1/25
This paper considers nonparametric and semiparametric regression models subject to monotonicity constraint. We use bagging as an alternative approach to Hall and Huang (2001). Asymptotic properties of...
Estimation in semiparametric models with missing data
Copulas imputation kernel smoothing missing at random nuisance function partially linear model
2016/1/20
This paper considers the problem of parameter estimation in a general class of semiparametric models when observations are subject to missingness at random.The semiparametric models allow for estimati...
Weighted Estimation of the Dependence Function for an Extreme-Value Distribution
Bivariate extreme dependence function jackknife empirical likeli- hood method
2016/1/19
Bivariate extreme-value distributions have been employed in modeling extremes in environmental sciences and risk management. An important issue is to estimate the dependence function such as Pickands ...
Estimation and goodness-of-fit for the Cox model with various types of censored data
Bivariate right censored data Bivariate data under univariate right censoring Bootstrap Doubly censored data Empirical likelihood Goodness-of-fit Partly interval-censored data
2015/12/11
The currently existing estimation methods and goodness-of-fit tests for the Cox model mainly deal with right censored data, but they do not have direct extension to other complicated types of censored...
