Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

Supervising Vulnerable Third Zone Distance Relay to Enhance Wide-Area Back-Up Protection Systems

open access: yesIEEE Access, 2022
Under dynamic stressed situations, distance relays are quite prone to zone-3 mal-trippings which are recognized as one of the primary causes for cascaded tripping in power systems and recent power black-outs.

A Novel Predictive and Non-Predictive Cooperative Model for Routing in Ad Hoc Networks

open access: yes, 2014
Adhoc networks are formed by intermediate nodes which agree to relay traffic.The link between nodes is broken when a node rejects to relay traffic. Various parameters like depreciation in the energy of a node, distance between nodes and mobility of the ...

Material Modification of Borofloat 33 During Scanning‐Based Microforming Using Femtosecond Laser Pulses

open access: yesAdvanced Optical Materials, EarlyView.
Possibilities for ablation‐free microforming of borosilicate glass using ultrashort laser pulses are presented. Depending on the laser parameters and scanning strategy, surface structures with profile heights of up to 20 µm could be produced. The work provides a comprehensive experimental and analytical characterization of the microforming process ...

Multi-Agent Distributed Deep Learning Algorithm to Detect Cyber-Attacks in Distance Relays

open access: yesIEEE Access, 2023
Distance relays are critical components in protection systems of power grids that can be attacked by cyber-attackers. Indeed, a cyber-attacker injects fake data into a distance relay to pretend a fault has happened, and the distance relay must be tripped.

Weakly Secure MDS Codes for Simple Multiple Access Networks

open access: yes, 2015
We consider a simple multiple access network (SMAN), where $k$ sources of unit rates transmit their data to a common sink via $n$ relays. Each relay is connected to the sink and to certain sources.
