Observer Design for Cyber-Physical Systems With State Delay and Sparse Sensor Attacks

open access: yesIEEE Access, 2021
This paper studies the problem of the secure state estimation of cyber-physical systems. The system model we studied is a class of discrete-time systems with state delay and sparse sensor attacks.

Reality, Information, and Information Observer

open access: yesProceedings, 2020
Up to now both information and its connection to reality do not have scientifically conclusive definitions, nor implicit origin. They emerge in observing multiple impulses’ interactive yes‒no actions modeling information bits.

A Relativistic Theory of Consciousness

open access: yesFrontiers in Psychology, 2022
In recent decades, the scientific study of consciousness has significantly increased our understanding of this elusive phenomenon. Yet, despite critical development in our understanding of the functional side of consciousness, we still lack a fundamental

Observing Functional Logic Computations [PDF]

open access: yes, 2004
A lightweight approach to debugging functional logic programs by observations is presented, implemented for the language Curry. The Curry Object Observation System (COOSy) comprises a portable library plus a viewing tool. A programmer can observe data structures and functions by annotating expressions in his program.

Fault Detection for Wireless Network Control Systems with Stochastic Uncertainties and Time Delays

open access: yesAbstract and Applied Analysis, 2014
The fault detection problem is investigated for a class of wireless network control systems which has stochastic uncertainties in the state-space matrices, combined with time delays and nonlinear disturbance. First, the system error observer is proposed.

Quantized Dissipative Observer-Based Output Feedback Control for a Class of Markovian Descriptor Jump Systems with Communication Delay

open access: yesComplexity, 2020
This paper investigates the problem of quantized dissipative observer-based output feedback control of Markovian descriptor jump systems with unavailable states, appearing networked-induced delay.

Observer based anti‐windup compensator with functional state feedback for time delay controllers—design and case study application

open access: yesIET Control Theory & Applications, 2022
Observer‐based anti‐windup compensator technique is proposed for controllers with time delays in the structure. Taking into consideration the functional character of such controllers and their infinite dimensionality, the feedback is designed as ...

Motor Function in the Late Phase After Stroke: Stroke Survivors’ Perspective [PDF]

open access: yesAnnals of Rehabilitation Medicine, 2020
Objective To examine the association between observer-assessed functional status and perceived recovery in the late phase after stroke. The study also aimed to determine whether observer-assessed functional improvements as a result of horse-riding ...

Video-assisted functional assessment of index pollicisation in congenital anomalies

open access: yesJournal of Children's Orthopaedics, 2016
Purpose Functional results of index pollicisation are usually assessed by the clinical score of Percival. This score is based on elementary hand movements and does not reflect the function of the neo thumb in daily life activities.
