Control-Oriented Physics-Based Modeling and Observer Design for State-of-Charge Estimation of Lithium-Ion Cells for High Current Applications

IEEE Transactions on Control Systems Technology, 2022
This article proposes a physics-based control-oriented model and observer design for the state-of-charge (SoC) estimation of lithium-ion cells for applications involving high magnitude fluctuating current profiles. The physics-based single-particle model

Observing physical activity in suburbs

Health & Place, 2008
This study examined the reliability of the block walk method (BWM) for observing physical activity on suburban sidewalks/streets. Trained observers simultaneously walked 40 sidewalk/street segments each 1525 m in length at a pace of 30.5 m/min while recording the number of individuals walking/bicycling/jogging and the address where the activity ...

Time, observer, and consciousness

Physics essays, 2022
In today’s physics, opinions on what is time are different. Some physicists deny the existence of time, and others think that time has physical existence. Nevertheless, time was never directly perceived by senses.

KKL Observer Synthesis for Nonlinear Systems via Physics-Informed Learning

arXiv.org
This paper proposes a novel learning approach for designing Kazantzis-Kravaris/Luenberger (KKL) observers for autonomous nonlinear systems. The design of a KKL observer involves finding an injective map that transforms the system state into a higher ...

Ubicon: Observing Physical and Social Activities

2012 IEEE International Conference on Green Computing and Communications, 2012
The connection of ubiquitous and social computing is an emerging research area which is combining two prominent areas of computer science. In this paper, we tackle this topic from different angles: We describe data mining methods for ubiquitous and social data, specifically focusing on physical and social activities, and provide exemplary analysis ...

Unsupervised Physics-Informed Neural Network-Based Nonlinear Observer Design for Autonomous Systems Using Contraction Analysis

European Control Conference
Contraction analysis offers, through elegant mathematical developments, a unified way of designing observers for a general class of nonlinear systems, where the observer correction term is obtained by solving an infinite-dimensional inequality that ...

A convolutional neural network-based model observer for breast CT images.

Medical Physics (Lancaster), 2020
PURPOSE In this paper, we propose a convolutional neural network (CNN)-based efficient model observer for breast computed tomography (CT) images. METHODS We first showed that the CNN-based model observer provided similar detection performance to the ...

Nature of the Physical Observer

AIP Conference Proceedings, 2010
The nature of the observer has long plagued physical science. Here we review the current status of cognitive science in the context of a cosmology of mind in an Anthropic Multiverse. The concept of an elan vital or life force has long been considered the elementary action principle driving the evolution of living‐systems by theologically minded ...
