The present study aimed to identify the perceptions of gas station workers about physical, chemical, biological and physiological risk factors to which they are exposed in their work environment; identify types of occupational accidents involving gas station workers and; report the development of a socioenvironmental intervention as a tool for risk communication to gas station workers. A quanti...

Abstract The number of vehicles on the road today is increasing due to rapid urbanisation, which necessitates increased fuel consumption. As a result, Petrol Pump Station (PPS) an important location that serves people in need fuel. This study evaluates these PPS within Batu Pahat District with goals determining existence distribution along main from Ayer Hitam Pahat, Johor, focus Jalan and Klua...

this paper is the representation of the computational and experimental methods of a new injector nozzle for a sequential port injection cng engine. the objective of this study was to review the previous research in the development of gaseous fuel injector for port injection cng engine converted from diesel engine. next, a simulation of the fuel flow of the new injector nozzle was made using flu...

The application of direction finding location technology in electronic warfare is becoming more and extensive. Aiming at the problem that traditional method will greatly affect accuracy when measurement information each observation station disturbed, a dual-station algorithm based on disturbance detection proposed. uses least squares to obtain target’s position moment, then designs an improved ...

1 The aim of this research is to develop a location model of rapid charging stations for electric vehicles (EV) 2 in urban areas considering the batteries’ state-of-charge (SOC) and the users’ charging and traveling 3 behaviors. EVs are developed to prepare for the energy crisis and reduce greenhouse gas emissions. In 4 order to help relieve range anxiety, an adequate number of EV charging stat...

Location management is one of the fundamental issues in cellular networks. It includes two operations: location update and paging. The goal of location management is to minimize the combined cost of these two operations. Recently a distance-based scheme using a pre-defined look-up table for location updates has been proposed. The table describes the relationship between the distance and the tim...

Wireless sensor networks are often constructed as asymmetric networks comprised of a large number of small, resource-constrained sensor nodes and a small number of relatively powerful base stations. A base station is vulnerable as a central point of failure in such networks. Typical packet traffic in a sensor network reveals pronounced patterns that allow an adversary analyzing packet traffic t...
