Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation

Undrained bearing capacity of obliquely-eccentrically loaded shallow foundations overlying a heterogeneous and inherently anisotropic clay deposit

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Clay deposits typically exhibit significant degrees of heterogeneity and anisotropy in their strength and stiffness properties. Such non-monotonic responses can significantly impact the stability analysis and design of overlying shallow foundations.

The Lagrange multiplier is not the shadow value of the limiting resource in the presence of strategically interacting agents [PDF]

open access: yes
In the case of a single net-benefit maximizing agent facing a resource constraint, the economic interpretation of the Lagrange multiplier is that of the shadow value of the constraining resource.

Validation of Neural Network Controllers for Uncertain Systems Using the Keep‐Close Approach: Robustness Analysis and Safety Verification

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT The safety verification of neural network (NN) controllers operating in uncertain environments characterized by unmodeled dynamics, nonlinearities, and time delays remains a fundamental challenge in robust control analysis. This article introduces a novel method, termed Keep‐Close, for analyzing the performance and robustness of uncertain ...

Pickin' up good vibrations: a systematic review of footfall detection and analysis in the realm of wildlife surveying

open access: yesWildlife Biology, EarlyView.
Exploration of new wildlife surveying methodologies that leverage advances in sensor technology and machine learning has led to tentative research into the application of seismology techniques. This, most commonly, involves the deployment of a footfall trap – a seismic sensor and data logger customised for wildlife footfall.

Estimación de la masa dinámica de un cúmulo de galaxias mediante el Teorema del Virial y técnicas emergentes

open access: yesAvances en Ciencias e Ingeniería
We estimate the dynamical mass of a Sloan Digital Sky Survey cluster using three techniques: (i) the classical virial theorem, (ii) a recent velocity–dispersion–mass scaling relation, and (iii) the caustic estimator based on the escape envelope in phase ...

A Practical Short-run Approach to Market Equilibrium [PDF]

open access: yes
The "short-run approach" calculates long-run producer optima and general equilibria bybuilding on short-run solutions to the producer's profit maximization problem and onprofit-based valuation of the fixed inputs. We outline this method and illustrate it

Waypoint Navigation of a 2D Drone in Stochastic Environment via Regularised Proximal Policy Optimisation

open access: yesArtificial Intelligence for Engineering, EarlyView.
We present a three‐stage training framework combining Behaviour Cloning warm‐starting with auxiliary‐regularised Deep Reinforcement Learning PPO fine‐tuning for 2D drone waypoint navigation under stochastic wind. Persistent imitation regularisation prevents catastrophic forgetting, achieving robust generalisation to unseen targets and out‐of ...

Pushing the Envelope: General Game Players Prove Theorems [PDF]

open access: yes, 2010
A general game player is a system that can play previously unknown games given nothing but their rules. A key to success in this endeavour is the ability to automatically gain knowledge about new games that follows from the rules without being explicitly given.
