Reducing Vulnerability to Cyber-Physical Attacks in Water Distribution Networks
(2018)
Cyber-Physical Systems (CPS), such as Water Distribution Networks (WDNs), deploy digital devices to monitor and control the behavior of physical processes. These digital devices, however, are susceptible to cyber and ...
Distributed Sensor Fault Accommodation of Multi-Zone HVAC Systems
(2018)
This paper presents a distributed methodology for controlling multi-zone Heating, Ventilation and Air-Conditioning (HVAC) systems and a fault accommodation scheme for reconfiguring the distributed controller in the presence ...
Online Approximation of Prediction Intervals Using Artificial Neural Networks
(Springer International Publishing, 2018)
Prediction intervals offer a means of assessing the uncertainty of artificial neural networks’ point predictions. In this work, we propose a hybrid approach for constructing prediction intervals, combining the Bootstrap ...
Queue-Based Resampling for Online Class Imbalance Learning
(Springer International Publishing, 2018)
Online class imbalance learning constitutes a new problem and an emerging research topic that focusses on the challenges of online learning under class imbalance and concept drift. Class imbalance deals with data streams ...
Path-based joint demand management and route guidance for multi-region traffic networks
(2019)
This work investigates the joint optimization problem of demand management and route guidance to minimize the time spent of vehicles in traffic networks characterized by well-defined regional fundamental diagrams. To account ...
LeakDB : A benchmark dataset for leakage diagnosis in water distribution networks
(2018)
The increase of streaming data from water utilities is enabling the development of real-time anomaly and fault detection algorithms that can detect events, such as pipe bursts and leakages. Currently, there is not a widely ...
Leak Detection in Water Distribution Systems Using Hydraulic Interval State Estimation
(2018)
This work develops a new algorithm based on interval hydraulic state estimation for leakage detection in urban water distribution systems using pressure sensors and smart meters. The proposed approach takes into consideration ...
An Adaptive Approach to Sensor Bias Fault Diagnosis and Accommodation for a Class of Input-Output Nonlinear Systems
(2018)
This paper presents an adaptive sensor fault diagnosis and accommodation scheme for multiple sensor bias faults for a class of input-output nonlinear systems subject to modeling uncertainty and measurement noise. The ...
Improving Contamination Detectability in Water Distribution Systems using Active Fault Detection
(2018)
Contamination event detection in Water Distribution Systems (WDS) is an important part of the overall procedures followed by operators to ensure the delivery of safe drinking water to consumers. ...
Probabilistic Search and Track with Multiple Mobile Agents
(2019)
In this paper we are interested in the task of searching and tracking multiple moving targets in a bounded surveillance area with a group of autonomous mobile agents. More specifically, we assume that targets can appear ...
