The perception of interpersonal distance is distorted by the Müller-Lyer illusion

Scientific Reports, 2021
There is growing interest in how human observers perceive social scenes containing multiple people. Interpersonal distance is a critical feature when appraising these scenes; proxemic cues are used by observers to infer whether two people are interacting,

Robust fault diagnosis of proton exchange membrane fuel cells using a Takagi-Sugeno interval observer approach [PDF]

, 2016
In this paper, the problem of robust fault diagnosis of proton exchange membrane (PEM) fuel cells is addressed by introducing the Takagi-Sugeno (TS) interval observers that consider uncertainty in a bounded context, adapting TS observers to the so-called

Robust Zonotopic Observer Design: Interval Observer versus Set-membership Approaches [PDF]

2019 4th Conference on Control and Fault Tolerant Systems (SysTol), 2019
The aim of this paper is to provide a robust observer design using a Linear Matrix Inequality (LMI) technique along with the analysis and comparison of the interval observer and set-membership approaches within the state estimation framework. The propagation of the uncertainty is taken into account considering a zonotopic-set representation.

Fault detection and isolation using viability theory and interval observers [PDF]

, 2018
This paper proposes the use of interval observers and viability theory in fault detection and isolation (FDI). Viability theory develops mathematical and algorithmic methods for investigating the viability constraints characterisation of dynamic ...

Sensor-fault detection and isolation using interval observers [PDF]

2013 Conference on Control and Fault-Tolerant Systems (SysTol), 2013
This paper proposes an interval observer-based sensor fault detection and isolation (FDI) approach for the closed-loop systems. In this proposed approach, residuals are defined in such a way that their components are independent of each other at the time instant after fault occurrence, namely kf + 1, where kf denotes the fault occurrence time instant ...

Intra- and Inter-Observer Variability of Quantitative Parameters Used in Contrast-Enhanced Ultrasound of Kidneys of Healthy Cats

Animals, 2022
Contrast-enhanced ultrasound (CEUS) is a non-invasive imaging technique which allows qualitative and quantitative assessment of tissue perfusion. Although CEUS offers numerous advantages, a major challenge remains the variability in tissue perfusion ...

Sensor-fault tolerance using robust MPC with set-based state estimation and active fault isolation [PDF]

, 2014
In this paper, a sensor fault-tolerant control (FTC) scheme using robust model predictive control (MPC) and set theoretic fault detection and isolation (FDI) is proposed.

On ‘observable’ Li–Yorke tuples for interval maps [PDF]

Nonlinearity, 2015
In this paper we study the set of Li-Yorke $d$-tuples and its $d$-dimensional Lebesgue measure for interval maps $T\colon [0,1] \to [0,1]$. If a topologically mixing $T$ preserves an absolutely continuous probability measure 9with respect to Lebesgue), then the $d$-tuples have Lebesgue full measure, but if $T$ preserves an infinite absolutely ...

Decentralization of Interval Observers for Robust Controlling and Monitoring a Class of Nonlinear Systems

SICE Journal of Control, Measurement, and System Integration, 2017
This paper tackles the problem of decentralizing interval observers for robust controlling and monitoring a class of nonlinear systems. The observer-based output feedback system considered in this paper is very different from classical systems in that an
