Owing to environmentally-destructive impact of aromatic hydrocarbons, such as benzene, benzene ethyl, toluene, and xylenes or BTEXs, these materials are classified as hazardous pollutants in the air. This study studies cancer and non-cancer risk in District 12 of Tehran Municipality, through these components for two groups of employees or storekeepers and gas station customers. By measuring pol...

The present sought to draw a comparison between Model Predictive Control performance and two other controllers named Simple PI and Selective PI in controlling large-scale natural gas transport networks. A nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in SIMULINK® environment of MATLAB®. Control schemes were designed to provide a s...

Exposure to the lead is public health problem and threat to environment with proven harmful impact on human, including industrial workers and general population. Harmful impacts of exposition to nervous, endocrine, hematological, cardiovascular, immune and reproductive system to the lead are well known. This article addresses the results of retrospective research carried out with attendants at ...

Giant-cell interstitial Pneumonia (GIP) is a very uncommon respiratory disease. The majority of cases of GIP are caused by exposure to cobalt, tungsten and other hard metals. In this report, we describe GIP in a patient who worked in gas station and dealt in propane gas vessels. He presented with clinical features of chronic interstitial lung disease and underwent an open lung biopsy that showe...

Introduction: Benzene has long been recognized as highly carcinogenic and the most cytotoxic of all air pollutants released by gas stations. Although several studies have conducted on accidents in process industry, very little work directed toward modeling risks caused leakage explosion toxic substances This knowledge could aid predicting vapor concentration inside station office buildings neig...

Remote monitoring and control system using Wireless communication have been developed to improve the efficiency of management solution for industrial facilities. However, those systems might be decreasing the efficiency and convenience because of connecting portable device using wired cable (RS232C or USB). This study is intended to design and develop a mobile smart city gas safety management s...

In the gas station problem we want to find the cheapest path between two vertices of an n-vertex graph. Our car has a specific fuel capacity and at each vertex we can fill our car with gas, with the fuel cost depending on the vertex. Furthermore, we are allowed at most ∆ stops for refuelling. In this short paper we provide an algorithm solving the problem in O(∆n2 + n2 logn) steps improving an ...

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...
