Journal ArticleDOI
Bidirectional handshaking LSTM for remaining useful life prediction
TL;DR: A new objective function that is suitable for the RUL estimation problem is proposed, as well as a new target generation approach for training LSTM networks, which requires making lesser assumptions about the actual degradation of the system.
Journal ArticleDOI
Optimal condition based maintenance with imperfect information and the proportional hazards model
TL;DR: In this paper, an optimal condition-based maintenance (CBM) replacement policy is derived based on the observed condition of the equipment, and the optimization of the optimal maintenance policy is formulated as a partially observed Markov decision process (POMDP), and the problem is solved using dynamic programming.
Journal ArticleDOI
Evaluating the Reliability Function and the Mean Residual Life for Equipment With Unobservable States
TL;DR: A model to calculate the reliability function, and the mean residual (remaining) life of a piece of equipment, when its degradation state is not directly observable is proposed, using a hidden Markov model.
Journal ArticleDOI
Enforcing security in Internet of Things frameworks: A Systematic Literature Review
TL;DR: An extensive description of security threats and challenges across the different layers of the architecture of IoT systems is presented and an emerging security challenge which has yet to be explained in-depth in previous studies is introduced.
Journal ArticleDOI
Parameter Estimation Methods for Condition-Based Maintenance With Indirect Observations
TL;DR: This article proposes methods to estimate the parameters of condition monitored equipment whose failure rate follows the Cox's time-dependent Proportional Hazards Model, and assumes that the equipment's unobservable degradation state transition follows a Hidden Markov Model.
