Performance Assessment of Friction Pendulum Bearings in Bridges via Data Assimilation

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Seismic isolation techniques are widely used in regions susceptible to earthquakes. From a long‐term maintenance perspective, it is crucial to develop methodologies for assessing the post‐installation performance of these systems based on monitored data.

A note on contributions concerning nonseparable spaces with respect to signal processing within Bayesian frameworks

Mathematical Methods in the Applied Sciences, Volume 46, Issue 1, Page 1178-1184, 15 January 2023., 2023
In this paper, we discuss the study of some signal processing problems within Bayesian frameworks and semigroups theory, in the case where the Banach space under consideration may be nonseparable. For applications, the suggested approach may be of interest in situations where approximation in the norm of the space is not possible.

Recorded recurrent deep reinforcement learning guidance laws for intercepting endoatmospheric maneuvering missiles

Defence Technology
This work proposes a recorded recurrent twin delayed deep deterministic (RRTD3) policy gradient algorithm to solve the challenge of constructing guidance laws for intercepting endoatmospheric maneuvering missiles with uncertainties and observation noise.

Coordinated Optimal Dispatch of Distribution Grids and P2P Energy Trading Markets

Energy Science &Engineering, EarlyView.
This study proposes a bi‐level optimization framework for distribution networks integrating P2P energy trading and shared storage. The upper level minimizes DSO costs (network losses, storage management) with voltage stability constraints, while the lower level optimizes prosumer profits via adaptive load/storage adjustments.

Health State Assessment Method for Complex Systems Based on Correlation Decoupled Belief Rule Base

Energy Science &Engineering, EarlyView.
In engineering practice, complex systems are subject to noise, and correlations can exist between attributes. This correlation can have a through effect on the validity of equipment health state evaluation. This paper proposes a belief rule base model that considers the correlation of attributes, which effectively enhances the accuracy and robustness ...

Linking chronic stress to insomnia symptoms in older adults: The role of stress co‐occurrence during the pandemic

Research in Nursing &Health, Volume 46, Issue 1, Page 68-79, February 2023., 2023
Abstract Studies examining the associations of chronic stressors with sleep health in older adults have shown conflicting results. While the COVID‐19 pandemic increased perceived stress at the population level, less is known about chronic stressors experienced by older adults in the context of the COVID‐19 pandemic and its impact on sleep health in an ...
