In this paper, we extend the result obtained in Kl Kim Dud for retrial queueing system with recurrent arrival flow to the case of periodic arrival process. We consider a single server retrial queueing system with lattice distribution of inter-arrival times, constant retrial rate and exponential service time distribution. For this queue, we derive the stationary distributions of the system states at arrival times and at an arbitrary times and the Laplace-Stieltjes transform of the customer sojourn time distribution. Little's formula for this system is proved. Results can be used for performance evaluation and capacity planning of telecommunication networks where effect of repeated calls is essential.
The problem of evaluating the radial electron–electron distribution function P0(r12) from the spin‐free 2‐particle density matrix P2(r1, r2Ir'1, r'2) is considered in detail. The analysis is first applied t...

The Industrial Internet of Things (IIoT) promises to provide an expanded awareness of field assets and equipment, access to data from across locations, and actionable insights for maximizing operational performance and safety of the oil and gas industry. Using automation and machine learning, with the application of predictive maintenance, efficiencies can be boosted and problems can be mitigated sooner and more effectively. The proposed system is mainly based on the data collection, processing, analysis, and modeling of an enormous number of historical and real-time data generated during the operation of the equipment on the edge side. The data-driven predictive maintenance used machine learning models and deep learning models to predict the remaining useful life (RUL). Bi-LSTM based prediction model has been trained on the cloud, and deployed onto the edge devices. The predictive maintenance process includes data acquisition, data processing, training of machine learning model, equipment health assessment, remaining useful life prediction, strategy formulation, and strategy execution. The predictive maintenance solution driven by the IIoT helps oil and gas companies make predictions before equipment failures have a significant impact on their company's safety level and profits to improve asset reliability and promote cost savings.
