The Noise-Sensitivity Phase Transition in Compressed Sensing
Approximate Message Passing Lasso Basis Pursuit Minimax Risk over Nearly- Black Objects Minimax Risk of Soft Thresholding
2015/8/20
Consider the noisy underdetermined system of linear equations: y = Ax0 + z0, with n N measurement matrix A, n < N, and Gaussian white noise z0 N(0; 2I). Both y and A are known, both x0 and z0 are...
Assessing the Sensitivity of Climate Change Targets to Policies of Land Use, Energy Demand, Low Carbon Energy and Population Growth
Climate Change Policy Sensitivity Analysis
2013/3/12
A reduced scale model of the coupled carbon cycle, population dynamics, energy system and land use characteristics is used to assess the sensitivity of atmospheric carbon to a variety of policies. Pol...
Bayesian Learning of Climate Sensitivity I: Synthetic Observations
Climate Uncertainty Bayesian Estimation Internal Variability
2013/2/27
The instrumental temperature records are affected by both external climate forcings—in particular, the increase of long-lived greenhouse gas emissions—and natural, internal variability. Estimates of t...
Sensitivity Analysis of Parameters in Water Quality Models and Water Environment Management
Water Quality Model Reclaimed Water Sensitivity Analysis Degradation Coefficient Stochastic Factors

Lidar measurements were made of the dispersion of the plume from a coastal industrial plant over three weeks between September 1996 and May 1998. 67 experimental runs were obtained, mostly of 30 min d...
A Photochemical Modelling Approach to Investigate O3 Sensitivity to NOx and VOCs in the Urban Atmosphere of Delhi
OZIPR Photochemical modelling Ozone NOx VOCs
2016/3/29
Ambient air pollutants data were used to evaluate whether O3 formation at a specific site (Sirifort)
in Delhi was limited by volatile organic compounds (VOCs) or oxides of nitrogen (NOx). For this
p...
