Due to their special environments, rural areas are susceptible to rodent outbreaks. Extensive damage to agricultural produce, equipment and buildings on the one hand and outbreaks of zoonotic diseases on the other are among the health and economic impacts of a rodent outbreak. Failure in controlling such events may even result in social issues, such as, village abandonment and mass migration to...
Introduction: Flammable dust particles when dispersed in air under certain conditions there is a risk of explosion. The aim of this study is determine the concentration of explosive dust, and the explosion risk assessment, in some a high risk industries of shahroud. Methods: To determine the level of dust in factories investigated, sampling and determine the concentration based on the method...
In hazardous repair of a repairable system, there is a strong probability of further failure during a period immediately following the repair. To model failures of such systems under failure-based maintenance, a class of point process models is proposed in which the failure intensity is a function only of equipment age and of time since most recent repair. Cost modelling requires the computatio...
Reliability estimation plays a significant role in the performance assessment of mining equipment, and aids in designing efficient and effective preventive maintenance strategies. Continuous and random/irregular occurrence of failures in a system could be the main cause for performance drop of machinery. The accomplishment of a projected level of production is possible only by an efficient oper...
Early Warning Analysis of Oil-Gas Field Equipment Failure Based on Statistical Model of Failure Rate
For failure prediction and information interaction problems of multi-equipment health management, fault prediction technology of multi-equipment and multi-parameter was proposed based on the system network. The state judgment and fault diagnosis algorithm is adopted by SOM self-organizing feature map neural network, the network parameters and node structure are changed adaptively, and the real-...
Background: FMEA is one of the best known system safety techniques widely used as an identification tool. The purpose of this study was to apply FMEA method to identify and assess the risks posed by power lines in a residential area is Hasyrabad, Ahwaz. Materials and Methods: First, we identified the power line process and the equipment involved. Later, we determined the failure modes of equipm...
Optimal Monitoring Equipment Placement for Fault and Attack Location in Transparent Optical Networks
Last decade, network security has become a very sensitive and important topic for equipment manufacturers and network operators. Physical layer security in opaque optical networks relies on the information obtained at the opaque nodes where the signal is electronically regenerated. However, in transparent optical networks, security is even more complex since the optical signals are not regenera...
Process safety and environment pollution demands are continuously increasing in the process industry. Apart from that, requirements regarding final product quality and production efficiency are higher and higher [1]. This can be achieved by applying advanced process monitoring and control techniques. Process control is heavily dependent on the quality of the data, so it is crucial to measure as...
