The role of road-tunnel ventilation has changed during the last decades. While in former years tunnel ventilation was responsible for providing an acceptable environment for tunnel users passing through the tunnel during normal operation conditions [30], nowadays the support of rescue conditions during a fire is dominating. The introduction of the fire case into the ventilation design resulted ...

The structural design and analysis of rotorcrafts is a complicated process in terms of material selection and inertial forces acting on it. This article presents the structural design of reliable highperformance rotorcraft in order to enhance the handling qualities during recovery purposes. Airframe structure of the rotorcraft is tailored based on the mission requirements. A low navigation perf...

Wireless communication is increasingly used to manage large-scale crises (e.g., natural disasters or a large-scale city fire). Communication has traditionally been based on cellular networks. However, real-life experience has proven that the base stations of these networks may collapse or become unreachable during a crisis. An incident commander must also know as much information as possible ab...

Target detection is a widely used application for area surveillance, elder care, and fire alarms; its purpose is to find a particular object or event in a region of interest. Usually, fixed observing stations or static sensor nodes are arranged uniformly in the field. However, each part of the field has a different probability of being intruded upon; if an object suddenly enters an area with fe...

AIMS Out-of-hospital cardiac arrest (OHCA) is a major public health problem. The objective of this study is to explore the effects of a dual dispatch early defibrillation programme. METHODS AND RESULTS In this pilot study, automated external defibrillators (AEDs) were provided to all 43 fire stations in Stockholm during 2005. Fire-fighters were dispatched in parallel with traditional emergenc...

Gas stations are an integral part of public space. However, they not only a place buying and selling but, unfortunately, also with significant risks, which include robberies and, at the same time, possibility fires explosions. The article is focused on safety gas theoretical presentation CPTED methodology. Together principles fire protection, should contribute to level safe environment. work pr...

the purpose of this study was to compare symptoms of ptsd among war affected people and employees in the fire station. totally, 60 people affected by war and 60 fire workers were selected using simple random sampling. by completing pcl inventory, samples of ptsd were characterized. data was analysed through spss software by independent t-test. as the results showed, severity of ptsd symptoms am...
