Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

open access: yesAdvanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

On the Event-Triggered Controller Design

IEEE Transactions on Automatic Control, 2020
The majority of event-triggered control (ETC) literature concentrates on designing triggering rule while assuming control input to emulate an analog design. In this article, however, both state and output feedback laws are jointly synthesized with the triggering law for nonlinear Lipschitz systems.

Event-Triggered Consensus Bernoulli Filtering

2018 21st International Conference on Information Fusion (FUSION), 2018
This paper focuses on reducing communication bandwidth and, consequently, energy consumption in the context of distributed target detection and tracking over a peer-to-peer sensor network. A consensus Bernoulli filter with event-triggered communication is developed by enforcing each node to transmit its local information to the neighbors only when a ...

Periodic asynchronous event-triggered control

2016 IEEE 55th Conference on Decision and Control (CDC), 2016
Asynchronous event-triggered control (AETC) is a control strategy proposed for wireless networked implementations whose sensor nodes have limited energy supplies. Local thresholds allow the sensors to sample and to transmit local measurements independently of each other.

Periodic Event-Triggered Control

2018
Recent developments in computer and communication technologies are leading to an increasingly networked and wireless world. This raises new challenging questions in the context of networked control systems, especially when the computation, communication, and energy resources of the system are limited.

Event-Triggered Distributed Multitarget Tracking

IEEE Transactions on Signal and Information Processing over Networks, 2019
This paper focuses on reducing communication bandwidth and, consequently, energy consumption in the context of distributed multitarget tracking over a peer-to-peer sensor network. A consensus cardinalized probability hypothesis density (CCPHD) filter with event-triggered communication is developed by enforcing each node to broadcast its local ...
