Recursive Parameter Estimation: Convergence

open access: yes, 2007
We consider estimation procedures which are recursive in the sense that each successive estimator is obtained from the previous one by a simple adjustment.

In‐Sensor Computing by Soft Threshold Logic Gates Under Different Humidity Conditions

open access: yesAdvanced Electronic Materials, EarlyView.
Soft nanocomposite materials, based on gold cluster‐assembled thin films implanted in polydimethylsiloxane substrate, can perform reliable processing in ambient environmental conditions. Humidity influences the resistive switching and computational capabilities of the nanocomposites, that can be used as multifunctional material combining sensing ...

Forecasting Lattice and Point Spatial Data: Comparison of Unilateral and Multilateral SAR Models

open access: yesForecasting
Spatial auto-regressive (SAR) models are widely used in geosciences for data analysis; their main feature is the presence of weight (W) matrices, which define the neighboring relationships between the spatial units.

Efficient recursive algorithms for functionals based on higher order derivatives of the multivariate Gaussian density

open access: yes, 2014
Many developments in Mathematics involve the computation of higher order derivatives of Gaussian density functions. The analysis of univariate Gaussian random variables is a well-established field whereas the analysis of their multivariate counterparts ...

Distance Dependent Localization Approach in Oil Reservoir History Matching: A Comparative Study [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2014
To perform any economic management of a petroleum reservoir in real time, a predictable and/or updateable model of reservoir along with uncertainty estimation ability is required. One relatively recent method is a sequential Monte Carlo implementation of

Sustainable Productivity Growth in Agriculture: The Role of Shifts in R&D Investments and Technology

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The objective of the paper is to evaluate the long‐term prospects of sustainable productivity growth linked to plausible assumptions on public agricultural R&D investments as the key productivity driver. Second, it investigates the role of changing R&D focus from yield maximization to input saving technologies (fertilizers and pesticides). The

Stochastic Approximation with Averaging Innovation Applied to Finance [PDF]

open access: yes, 2012
The aim of the paper is to establish a convergence theorem for multi-dimensional stochastic approximation when the "innovations" satisfy some "light" averaging properties in the presence of a pathwise Lyapunov function.

Price Transmission and Leadership in the Global Poultry Market: Results From Parametric and Nonparametric Approaches

open access: yesAgribusiness, EarlyView.
ABSTRACT Brazil and the United States account for more than 40% of global poultry exports, with China and South Korea among their major destination markets. This study examines price transmission and market linkages between Brazil and the United States using monthly poultry export price data from January 1990 to December 2024. It also assesses which of
