Improving agricultural performance for the working poverty reduction in the European Union
agricultural holdings employment in-work at-risk-of-poverty
2016/7/6
The main objective of the paper is to highlight the impact of agricultural performance on working poverty in the EU countries, in the 2008–2013 period, for identifying some measures that need to be ta...
A Primal-Dual Potential Reduction Method for Problems Involving Matrix Inequalities
Interior point algorithms Linear matrix inequaliües Semidefinite programming
2015/7/13
We describe a potential reduction method for convex optimization problems involving matrix inequalities. The method is based on the theory developed by Nesterov and Nemirovsky and generalizes Gonzaga ...
Load Reduction of Wind Turbines Using Receding Horizon Control
Load Reduction Wind Turbines Receding Horizon Control
2015/7/9
Large scale wind turbines are lightly damped mechanical structures driven by wind that is constantly fluctuating. In this paper, we address the design of a model-based receding horizon control scheme ...
Approximating Martingales for Variance Reduction in Markov Process Simulation
Variance reduction Markov process simulation martingale
2015/7/8
“Knowledge of either analytical or numerical approximations should enable more efficient simulation estimators to be constructed.” This principle seems intuitively plausible and certainly attractive, ...
STABLE REDUCTION TO KKT SYSTEMS IN BARRIER METHODS FOR LINEAR AND QUADRATIC PROGRAMMING
interior methods barrier methods linear programming
2015/7/3
We discuss methods for solving the key linear equations within primal-dual barrier
methods for linear and quadratic programming. Following Freund and Jarre, we explore methods
for reducing the Newto...
Lyapunov-Schmidt reduction algorithm for three-dimensional discrete vortices
Three-dimensional vortex configuration discrete nonlinear discrete vortex coupling
2014/12/25
We address the persistence and stability of three-dimensional vortex configurations in the discrete nonlinear Schrödinger equation and develop a symbolic package based on Wolfram’s MATHEMATICA fo...
Obstacles and disaster risk reduction: Survey of Memphis organizations
Disasters Risk management Information management Organizations Tennessee Memphis
2014/11/27
The disaster management literature is replete with surveys at the community and household levels. However, few exist at the organizational level. This study attempts to fill this void by examining the...
Topics in Multivariate Time Series Analysis: Statistical Control, Dimension Reduction Visualization and Thir Business Applications
Topics in Multivariate Time Series Analysis Statistical Control Dimension Reduction Visualization Their Business Applications
2014/10/28
Most business processes are, by nature, multivariate and autocorrelated. Highdimensionality is rooted in processes where more than one variable is considered simultaneously to provide a more comprehen...

Many mathematical models involve input parameters, which are not precisely known. Global sensitivity analysis aims to identify the parameters whose uncertainty has the largest impact on the variabilit...
现有基于Lattice Reduction (LR)技术的多输入多输出(MIMO)系统检测算法,虽然可以有效地提高MIMO系统的误比特率(BER)性能,但其检测性能与最优的最大似然(ML)算法相比仍然存在差距。针对这一问题,提出了一种新的基于信道分组的线性Lattice Reduction辅助检测算法。该算法首先将信道分为两组,对通过条件最差子信道的信号采用最优的ML算法检测,然后将其从接收到的信...
Iterative bias reduction multivariate smoothing in R: The ibr package
multivariate smoothing L2 boosting thin-plate splines kernel regression R
2011/6/20
In multivariate nonparametric analysis, sparseness of the co-
variates also called curse of dimensionality, forces one to use large smoothing
parameters. This leads to a biased smoother. Instead of ...
