Event-triggered fault detection for networked control systems subject to packet dropout
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference Paper)This paper investigates the problem of fault detection for discrete-time networked systems subject to packet dropout under an event-triggered scheme. The packet dropout has been modeled as a Markov process and an event-triggered ... -
Event-Triggered fault detection, isolation and control design of linear systems
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)In this paper, the problem of event-Triggered integrated fault detection, isolation and control (E-IFDIC) for discrete-Time linear systems is considered. Using a filter to represent, characterize, and specify the E-IFDIC ... -
Event-triggered fault estimation and accommodation design for linear systems
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)The problem of event-triggered active fault-tolerant control (E-AFTC) of discrete-time linear systems is addressed in this paper by using an integrated design of event-triggered fault/state estimator with a fault-tolerant ... -
Event-Triggered Multiobjective Control and Fault Diagnosis: A Unified Framework
( IEEE Computer Society , 2017 , Article)In the area of robust control, fault diagnosis, and fault tolerant control of linear systems, many fundamental problems can be recast as H-\infty, l-1 and generalized H-2 control frameworks leading to the so-called mixed ... -
Event-triggered particle filtering and Cramer-Rao lower bound computation
( SAGE Publications Ltd , 2021 , Article)In this article, an event-triggered particle filtering method is presented to estimate the states of stochastic nonlinear systems with the ultimate goal to reduce the information exchange in networked systems. In the ... -
Event-triggered robust fault diagnosis and control of linear Roesser systems: A unified framework
( Elsevier Ltd , 2021 , Article)In this paper, the problem of simultaneous robust fault detection and isolation and control in the presence of the stochastic, energy bounded, and peak bounded disturbances for linear Roesser systems through the network ... -
Event-triggered simultaneous fault detection and consensus control for linear multi-agent systems
( Institute of Electrical and Electronics Engineers Inc. , 2016 , Conference Paper)This paper investigates the design and development of event-triggered simultaneous fault detection and consensus control (SFDCC) problem for a network of linear agents. Each agent is equipped with a distributed SFDCC unit ... -
Event-triggered simultaneous fault detection and tracking control for multi-agent systems
( Taylor and Francis Ltd. , 2019 , Article)The main aim of this study is to design distributed simultaneous fault detection and control units for multi-agent systems subject to limited communication and energy resources. For this purpose, each agent is equipped ... -
Event-Triggered Suboptimal Tracking Controller Design for a Class of Nonlinear Discrete-Time Systems
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)In this paper, using the state-dependent Riccati equation approach, an event-triggered technique is proposed to solve the tracking problem for a broad class of nonlinear discrete-time networked control systems. It is shown ... -
EveTAR: A new test collection for event detection in Arabic tweets
( Association for Computing Machinery, Inc , 2016 , Conference Paper)Research on event detection in Twitter is often obstructed by the lack of publicly-available evaluation mechanisms such as test collections; this problem is more severe when considering the scarcity of them in languages ... -
EveTAR: building a large-scale multi-task test collection over Arabic tweets
( Springer Netherlands , 2018 , Article)This article introduces a new language-independent approach for creating a large-scale high-quality test collection of tweets that supports multiple information retrieval (IR) tasks without running a shared-task campaign. ... -
Evidence by ac-conductivity for the higher mobility of boron (over aluminium)-associated Brønsted sites in boron-modified HZSM-5
( Elsevier , 1996 , Article)A correlation ac-conductivity analysis is performed at 102–105 Hz, 373–613 K and 0.8 V for characterizing the effect of increasing boron incorporation in HZSM-5 lattice on altered electric features in BZSM-5 samples of ... -
Evidence for gesture-speech mismatch detection impairments in schizophrenia
( Elsevier Ireland Ltd , 2019 , Article)Patients with schizophrenia suffer from impairments in the perception and production of gestures. The extent to which patients can access the semantic association between speech and co-verbal gestures in concrete or ... -
Evidence for some prostaglandins in Allium sativum extracts
( John Wiley & Sons, Ltd. , 1988 , Article)Homogenized garlic (Allium sativum Linn.) was extracted successively with organic solvents and the prostaglandin-rich fraction separated. Fractionation of the extract with column chromatography was performed. TLC of the ... -
