A structurally localized ensemble Kalman filtering approach

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We derive an inherently localized ensemble Kalman filtering (EnKF) approach, avoiding the need for any auxiliary localization technique. The idea is to first use the variational Bayesian optimization to approximate the (continuous) state analysis probability density function (pdf) by a product of independent marginal pdfs corresponding to small ...

Modelling recursion [PDF]

open access: yes
The purpose of my research is to examine and explore the ways that undergraduate students understand the concept of recursion. In order to do this, I have designed computer-based software, which provides students with a virtual and interactive ...

A principled approach to programming with nested types in Haskell

open access: yes, 2009
Initial algebra semantics is one of the cornerstones of the theory of modern functional programming languages. For each inductive data type, it provides a Church encoding for that type, a build combinator which constructs data of that type, a fold ...

Biomimetic Multifinger Tactile Sensing and Contact‐Regulated Palpation for Autonomous Breast Tumor Localization

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Early detection of breast abnormalities remains challenging: manual palpation is subjective and operator‐dependent, while imaging modalities may miss small or subtle stiffness anomalies. This paper presents a biomimetic multifinger robotic palpation approach intended to support early breast‐cancer screening and follow‐up assessment as a proof ...

Digital three-stage recursive-separable image processing filter with variable sizes of scanning multielement aperture

open access: yesРоссийский технологический журнал
Objectives. The main aim of digital image processing is to increase clarity while maintaining image quality and eliminate noise. However, the amount of information contained in digital image files is growing year after year.

U.S. Path to Industry 4.0: Reassessing Supply Chain Digitalization and AI for Industrial Sustainability

open access: yesSustainable Development, EarlyView.
ABSTRACT Currently, the United States (U.S.) has issues with declining industrial values and supply chain digitalization, which threaten the country's industrialization and Industry 4.0 transformation. The country needs to reverse this trend through effective policy implementation. However, the literature's understanding of effective policies' long‐run

Recursion as a Human Universal and as a Primitive

open access: yesBiolinguistics, 2010
This contribution asks, in an empirical rather than formal perspective, whether a range of descriptive phenomena in grammar usually characterized in terms of ‘recursion’ actually exhibit recursion. It is concluded that empirical evidence does not support

How Tariffs Shape Trade‐Embodied Emissions in the European Union: Sectoral Heterogeneity in Final Demand

open access: yesSustainable Development, EarlyView.
ABSTRACT This paper examines the environmental implications of tariffs on greenhouse gas emissions embodied in extra‐European Union imports consumed by domestic final demand in the EU. Using a multidimensional country‐sector‐year framework, the study investigates whether tariff changes are associated with variations in trade‐embodied emissions and ...

Some Puzzling Foundational Issues: The Reading Program

open access: yesCatalan Journal of Linguistics, 2019
This is an annotated transcription of Noam Chomsky’s keynote presentation at the University of Reading, in May 2017. Here, Chomsky reviews some foundational aspects of the theory of structure building: essentially, Merge and Label.
