Pipelines, wellbores and ground installations are permanently controlled by sensors spread across the crucial points in the whole area. One of the most popular techniques to support proper oil drive in a wellbore is a Gas Lift. In this paper we present the concept of using wireless sensor network (WSN) in the oil and gas industry installations. Assuming that Gas Lift Valves (GLVs) in a wellbore...

Water-cooled Al beam dumps are used at SLAC to absorb the energy of high-intensity electron beams through development of a massive electromagnetic cascade. The aluminum becomes activated and constitutes a moderate radiation hazard. Decay-curve measurements made near two such dump installations are presented and compared with calculation. The most important radionuclides produced in the Al are i...

This study aims to describe current risk management practices and policies across the world in relation to personal exposures from devices emitting radiofrequency fields, environmental exposures from fixed installations and exposures in the work environment. Data from 86 countries representing all WHO regions were collected through a survey. The majority of countries (76.8 %) had set exposure l...

Advances in technology and the increased use of home medical devices, will revolutionise the way public healthcare is administered. Homes and their associated networks in conjunction with such devices will take over many mundane healthcare tasks and manage new and enriched lifestyle choices that affect our overall quality of life. Through the combination of wireless and fixed networking infrast...

We evaluated 10 years of reported hazardous cargo incident information from the U.S. Air Force and Naval Safety Centers. In this first of two papers describing the hazardous cargo problems reported by the two services, we describe types of aircraft and types of hazardous cargo involved in incidents not causing aircraft mishaps. Normally, hazardous cargo must be manifested as such and no passeng...

It has been approximately ten (10) years since the first electrostatic precipitator was applied to an incinerator in the United States by the City of New York. Since that time, numerous installations have been made on various types of incinerators. This paper gives a brief description of the majority of the installations as well as actual performance data as compared to manufacturers' guarantee...

one of the most effective tools for decline cost and time, quality improvement and consequently project performance enhancement especially in construction projects, is value engineering. there are linguistic judgments in many cases of value engineering studies in construction projects such as interior design, mechanical installations design, and etc. therefore multiple attribute decision-making...

Issues of hazardous waste management are major concerns in the countries of eastern and central Europe. A National Institute of Environmental Health Sciences-supported conference was held in Prague, Czech Republic, as a part of a continuing effort to provide information and promote discussion among the countries of eastern and central Europe on issues related to hazardous wastes. The focus was ...

The paper presents a method of determination of ground fault current distribution when HV (high voltage) substations are located in urban or suburban areas, or where many relevant data necessary for determination of this distribution are uncertain or completely unknown. The problem appears as a consequence of the fact that many of urban metal installations are situated under the surface of the ...
