Recently, many applications in wireless sensor networks (WSNs) have been discussed. Navigation with WSNs is among the most heated debated ones. Previous navigation algorithms attempt to find safe and efficient escape paths for individuals under various environmental dynamics but ignore possible congestion caused by the individuals rushing for the exits. Moreover, most previous works have overlo...

This paper introduces a new approach for selecting the location of Radio Frequency (RF) sensors used for detecting objects in a building. It is assumed that a building, its map and its main building materials are given. A number of moving or static objects, carrying RF tags are to be detected in this building. RF sensors are used to detect the tags. The time interval between the moment that the...

Communication support is a serious limitation for Latin American firefighters when they deal with emergency situations. The insufficient number of radio channels and the impossibility to deliver digital information force firemen to improvise during response processes, e.g., to make decisions using their experience and poor or null supporting information. These improvised actions affect the time...

The Fire Brigade of the State of Rio de Janeiro (CBMERJ) is Brazil's most ancient and is one of the military forces of the state. It has the primary function of activities related to civil defense of the state. This study aims to contribute to the improvement of the current situation by proposing a solution of eliminating totally or at least mitigating risks of ergonomic injury, since all opera...

Where to put the monitoring points in a system is a very common problem (environment, industry, health, and so on). We show that Archimedes maps, that is, measure preserving transformations, provide the right tool for this problem. Conversely, we insist that random exploration, often preferred because of simplicity and low cost, should definitely be avoided. Many of our contracts, both in indus...

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), published by the American Psychiatric Association, the post-traumatic stress disorder (PTSD) is diagnosed when a person: (a) is exposed to a traumatic event that is well outside the range of usual human experience accompanied by intense fear or horror; (b) reexperiences the event in his/her thoughts, dreams and dai...

posttraumatic stress disorder (ptsd) occurs following exposure to potentially traumatic experiences such as those regularly encountered by emergency service workers (police, ambulance and firemen/women) and servicemen/women. ptsd is associated with high rates of somatic comorbidities including metabolic syndrome contributing to an excess mortality rate due to preventable cardiovascular diseases...
