Under-sea Monitoring System

Real-time acoustic tomography system and the experience of Caspian current sea monitoring

The Acoustic Tomography (AT) systems are used to monitor long-term and continuous flow in rivers, seas and oceans. One of the disadvantages of existing systems in Iran is the inability of real-time/automated measurements. In this study, by adding a raspberry Pi computer to the system and performing the required programming, it was possible to do online monitoring. The data are transferred to th...

Forecasting System Monitoring under Non-normal Input Noise Distributions

In quantitative forecasting models and tracking signal methods, input noise is often assumed to be normally and independently distributed. The goal of this research was to study the distribution of tracking signal and build new monitoring schemes for when the input noise distribution is not necessarily normal. A demand process in the Wilson inventory model was simulated using several input nois...

His reasons were not, however, as obscure as Nemo’s. He had inherited t...
