The Mesochronous Dual-Clock FIFO Buffer
(2020)
To increase system composability and facilitate timing closure, fully synchronous clocking is replaced by more relaxed clocking schemes, such as mesochronous clocking. Under this regime, the modules at the two ends of a ...
Active Contamination Detection in Water-Distribution Systems
(2020)
In this paper, we propose a novel methodology for altering the area monitored by water quality sensors in water distribution systems (WDS) when there is suspicion of a contamination event. The proposed active contamination ...
Optimal Elevator Group Control via Deep Asynchronous Actor-Critic Learning
(2020)
In this article, a new deep reinforcement learning (RL) method, called asynchronous advantage actor-critic (A3C) method, is developed to solve the optimal control problem of elevator group control systems (EGCSs). The main ...
Distributed Fault-Tolerant Control of Multiagent Systems: An Adaptive Learning Approach
(2020)
This paper focuses on developing a distributed leader-following fault-tolerant tracking control scheme for a class of high-order nonlinear uncertain multiagent systems. Neural network-based adaptive learning algorithms are ...
An efficient Navier-Stokes based numerical wave tank using fast Poisson solvers and the immersed boundary method
(2020)
An efficient numerical model for wave induced flows and their interaction with impermeable coastal structures, is presented. Using recent developments in the field of two-fluid (water/air) Navier-Stokes (NS) simulations, ...
Variable property DNS of differentially heated cavities filled with air
(2020)
Direct numerical simulations (DNS) of the thermally-driven flow of air inside differentially heated cavities (DHC) are presented. The variation of air properties is taken into account using the low-Mach approximation, to ...
Specific Absorption Rate-Aware Beamforming in MISO Downlink SWIPT Systems
(2020)
This paper investigates the optimal transmit beamforming design of simultaneous wireless information and power transfer (SWIPT) in the multiuser multiple-input-single-output (MISO) downlink with specific absorption rate ...
Wall Fusion of Buried Pipelines Due to Direct Lightning Strikes: Field, Laboratory, and Simulation Investigation of the Damaging Mechanism
(2020)
Wall fusion of buried pipelines can occur if the driving voltage and available current is sufficiently high. For example, it can occur from direct lightning strikes to earth, close to the pipelines' routing. However, not ...
Neural network-based construction of online prediction intervals
(2020)
With the emergence of online learning systems which generate ever-growing amounts of data, quantifying the uncertainty in predictions regarding the system’s operation is becoming increasingly more important. Prediction ...
Modeling and Performance Comparison of Screen-Printed, Impedance Spectroscopy Probes for Harsh Environments
(2020)
This paper compares the simulated performance of three different screen-printed probe geometries for Electrochemical Impedance Spectroscopy probes for use in harsh environments. The best performing probe, which is equipped ...
