Application of Model-based Geostatistics for Natural Hazards Identification
Model-based geostatistics Ordinary kriging Kriging with external drift Natural hazard
2015/12/1
Annually much agricultural productions are lost by natural hazards such as flooding, extreme temperature, and drought. In this research we present a procedure to identify such hazards for rice croppin...
Algorithmic Development of an Optimal Path Computation Model Based on Topographic Map Features
GIS Mapping Modelling,
2015/7/6
Path finding problems have attracted widespread research interests with different GIS-T applications such as Logistics applications,
Infrastructure Planning and Travel Demand analysis. Previous resea...
The identification of a solar signal in climate records of the last 500 years using proxy and model-based analysis and the implications for natural climate variability
Satellite instruments car the solar constant solar energy output climate the climate warming
2014/10/22
There has been confirmation in the last two decades, through instrumental measurements onboard satellites, that the 'solar constant' does, as has long been hypothesized, vary. While there is no consen...
Gene-centric gene-gene interaction: A model-based kernel machine method
Allele matching kernel association study gene-clustered SNPs genomic similarity reproducing kernel Hilbert space quantitative traits
2012/11/23
Much of the natural variation for a complex trait can be explained by variation in DNA sequence levels. As part of sequence variation, gene-gene interaction has been ubiquitously observed in nature, w...
Learning Model-Based Sparsity via Projected Gradient Descent
Model-Based Sparsity Projected Gradient Descent
2012/11/22
Several convex formulation methods have been proposed previously for statistical estimation with structured sparsity as the prior. These methods often require a carefully tuned regularization paramete...
Weights and degrees in a random graph model based on 3-interactions
Martingale random graph preferential attachment scale-free property
2012/6/19
In a random graph model based on 3-interactions we give the joint asymptotic distribution of weights and degrees and prove scale-free property for the model. Moreover, we determine the asymptotics of ...
Biased swimming cells do not disperse in pipes as tracers: a population model based on microscale behaviour
Algae dispersion swimming pipe
2012/5/17
There is much current interest in modelling suspensions of algae and other micro-organisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispe...
A two-component jet model based on the Blandford-Znajek and Blandford-Payne processes
two-component jet model Blandford-Znajek Blandford-Payne processes
2012/2/23
We propose a two-component jet model consistent with the observations of several gamma ray bursts (GRBs) and active galactic nuclei (AGNs). The jet consists of inner and outer components, and they are...
The Wartime Bridge Reliability Evaluation Model Based on Birth-and-Death Process
Wartime Bridge Reliability Evaluation Birth-And-Death Process
2013/1/30
At first, the concept of bridge reliability is given, followed with its mathematic model. Then, based on the analysis about the mechanism of the damage and repair of bridges, and the state diversion o...
Recursions in Calogero-Sutherland Model Based on Virasoro Singular Vectors
Calogero-Sutherland Model Jack Symmetric Function Recursion Relations Integral Representation
2011/10/9
Abstract: The present work is much motivated by finding an explicit way in the construction of the Jack symmetric function, which is the spectrum generating function for the Calogero-Sutherland(CS) mo...
Change point analysis of an exponential model based on Phi-divergence test-statistics: simulated critical points case
Change point Exponential model Likelihood ratio test Power-divergence test statistic
2011/8/25
Abstract: Recently Batsidis \textit{et al.} (2011) have presented a new procedure based on divergence measures for testing the hypothesis of the existence of a change point in exponential populations....

A Non-linearized PLS Model Based on Multivariate Dominant Factor for Laser-induced Breakdown Spectroscopy Measurements
LIBS, partial least square, quantitative measurement laser diagnostics
2011/8/29
A multivariate dominant factor based non-linearized PLS model is proposed. The intensities of different lines were taken to construct a multivariate dominant factor model, which describes the dominant...
A cyclic cosmological model based on the f(ρ) modified theory of gravity

2011/8/26
We consider FLRW cosmological models for perfect fluid (with rho as the energy density) in the frame work of the f(rho) modified theory of gravity [V. N. Tunyak, Russ. Phys. J. 21, 1221 (1978); J. R. ...

Reliability robustness rainfall compound weather pattern sub-sampling
2011/3/14
A new probabilistic model for daily rainfall, named MEWP (Multi Exponential Weather Pattern) distribution, has been introduced in Garavaglia et al. (2010). This model provides estimates of extreme rai...
