Conditional Stochastic Simulations of Flow and Transport with Karhunen-Loève Expansions, Stochastic Collocation, and Sequential Gaussian Simulation

open access: yesJournal of Applied Mathematics, 2014
We derive a new method of conditional Karhunen-Loève (KL) expansions for stochastic coefficients in models of flow and transport in the subsurface, and in particular for the heterogeneous random permeability field.

All‐sky assimilation impacts of the Tomorrow.io microwave sounder constellation on global weather forecasts

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Key Findings: An assimilation methodology is established for the Tomorrow.io microwave sounder (TMS) flying on CubeSats in sun‐synchronous and inclined orbits, and in all cloud scenes. The TMS has a significant impact on weather forecast lead times up to 3 days in the Tropics in a research‐quality numerical weather prediction setting, and yields water ...

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review

open access: yesSystems Engineering, EarlyView.
ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

Heterogeneous Spillover Effects: How FDI in Resources Extraction, Manufacturing, and Services Affect Sectoral Carbon Emissions in the MENA Region

open access: yesNatural Resources Forum, EarlyView.
ABSTRACT The MENA region faces a critical challenge: balancing economic growth spurred by foreign direct investment (FDI) with environmental sustainability. While FDI can bring technological advancements and capital, concerns exist about its potential to exacerbate environmental degradation, particularly carbon emissions.

The Influence of Random Element Displacement on DOA Estimates Obtained with (Khatri–Rao-)Root-MUSIC

open access: yesSensors, 2014
Although a wide range of direction of arrival (DOA) estimation algorithms has been described for a diverse range of array configurations, no specific stochastic analysis framework has been established to assess the probability density function of the ...

Estimating the Effective Permittivity for Reconstructing Accurate Microwave-Radar Images. [PDF]

open access: yesPLoS ONE, 2016
We present preliminary results from a method for estimating the optimal effective permittivity for reconstructing microwave-radar images. Using knowledge of how microwave-radar images are formed, we identify characteristics that are typical of good ...

Is acquisition‐related foreign direct investment during an economic crisis detrimental for domestic innovation?

open access: yesThe Scandinavian Journal of Economics, EarlyView.
Abstract We study how acquisition‐related foreign direct investment during economic crises affects R&D investments and the direction of innovation of target firms, compared with acquisitions made during periods of strong economic growth. Using a panel of Spanish firms, we find that foreign multinationals cherry‐pick the best domestic firms ...
