the awareness of administrative organization of rescue and relief operation from spatial and temporal dimensions is pre requirement of rescue and relief. this subject and existence of accessible transportation networks that can save their performance after emergency situations are the most important parameters in efficiency of rescue and relief operation. the position of firefighting stations a...

The Candidate Physical Ability Test (CPAT) is used to assess the physical fitness of firefighter candidates. The test is comprised of eight tasks which simulate real firefighting duties and demands. These tasks, whether executed during the CPAT or during a real firefighting scenario, are often performed in a cardiovascularly fatigued state. Given that cardiovascular fatigue is a large component...

Firefighting demands performing heavy muscular work under adverse and potentially dangerous conditions. Although the physiological and psychological responses to simulated firefighting activities have been described, the heat strain has not been characterised using standardised indices of exercise-heat strain. The purpose of the study is to describe the physiological and perceptual strain assoc...

The Firefighting problem is defined as follows. At time t = 0, a fire breaks out at a vertex of a graph. At each time step t > 0, a firefighter permanently defends (protects) an unburned vertex, and the fire then spread to all undefended neighbors from the vertices on fire. This process stops when the fire cannot spread anymore. The goal is to find a sequence of vertices for the firefighter tha...

Firefighting is a stressful and hazardous job. Persons engaged in firefighting are highly exposed to work-related stress as well as to smoke containing a host of chemicals potentially harmful to human health. In order to elucidate whether firefighting affects neuroendocrine and behavioral responses of firefighters, plasma catecholamine (CA) levels and the prevalence of neurobehavioral symptoms ...

abstract one of the major factors on the amount of water resources is river flow which is so dependent to the hydrologic and meteorologic phenomena. simulation and forecasting of river flow makes the decision maker capable to effectively manage the water resources projects. so, simulation and forecasting models such as artificial neural networks (anns) are commonly used for simulation and predi...

Abstract In response to manufacturing strategy demand, fire accidents in petroleum, chemical, forestry, and high-rise buildings are on the rise. Although firefighting robot can replace rescue workers who come into dangerous site, electronic devices’ thermal failure problem caused by high temperatures whole equipment is bigger. The proportion of device has a significant impact normal operation e...
