This research study focuses on the discussion regarding the development of fault detection in gas metering station using an Artificial Neural Network (ANN). The proposed model of fault detection applies ANN approach in order to provide a good detection method for billing purpose. However, one of the main problems faced by gas metering system is the undiagnosed faulty condition of measurement. M...

Measurements on nuclei far from stability can and will continue to provide the most stringent tests of nuclear theories. Detailed measurements of masses, half-lives, and decay processes will be possible with thermalized beams of ions from the NSCL s Coupled Cyclotron. Even the most exotic nuclei can be studied if the thermalization and subsequent extraction are rapid (~10 ms). For example, the ...

For longer distances, natural gas is transported through transit pipeline at high pressures. In a place of consumption or at passing into a lower pressure pipeline, the pressure of the gas must be reduced. In Iran, the common procedure of reducing pressure in natural gas station is using expansion valves, which causes the waste of large amount of energy. Combined heat and power (CHP) systems ha...

The results of analysis of mineral fibres in lung tissues from 10 paraoccupational cases of malignant mesothelioma were compared with analysis obtained from seven cases of malignant mesotheliomas that had developed in gas mask workers. Nine of the paraoccupational cases were considered to have developed their tumours because of exposure to asbestos on their husbands' working clothes and one can...

The following example illustrates the problem treated in this paper: Two gas stations are located one after the other on a main road. A driver who needs to ll his tank sees the queue situation at the rst station but not at the second one. The driver estimates the expected waiting time at the rst station, compares it to the conditional expected waiting time at the second one, and decides which s...

tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. in this research, in four stations of anzali lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured and evaluated with molecular indicator lin...

In this paper, we analyzed the influence of time required to begin coping behaviors of managers in chemical terrorism. In order to calculate the damage of chemical attacks in a major rail station, our network model-based pedestrian simulator was applied with hazard prediction systems of indoor gas diffusion. Our analysis was used for enlightening the managers of the rail station in a tabletop e...
