Introduction / objectives The epidemic influenza A (H1N1) virus is the result of reassortment between genetic material from the human, avian and swine virus. In July 2009 the World Health Organization published the sustained transmission of the virus in two continents, characterizing the epidemy and occurring prompt response by this agency worldwide. The objetive to report the experience of the...

several investigations demonstrated that anxiety is the most common mental health disorder worldwide affected about one in 13 people. anxiety disorders are more commonly reported in western societies but it is also a main health problem in non-western countries as stress and anxiety levels have drastically increased over the last two decades. several wars in middle eastern countries in the last...

Clusters of infected individuals are defined on data from health laboratories, but this quantity has not been defined and characterized by epidemy models on statistical physics. For a system of mobile agents we simulate a model of infection without immunization and show that all the moments of the cluster size distribution at the critical rate of infection are characterized by only one exponent...

We consider vaccination control of the spread of an epidemy in a classical SIR model. Our approach aims at controlling the number infected at the peak. It differs from the widespread stationary vaccination control strategies, based upon having control reproductive number stricly less than one to ensure convergence, and also from cost minimization optimal control ones. Indeed, instead of aiming ...

Traditional deterministic modeling of epidemics is usually based on a linear system differential equations in which compartment transitions are proportional to their population, implicitly assuming an exponential process for leaving as happens radioactive decay. Nonetheless, this assumption quite unrealistic since it permits class transition such the passage from illness recovery that does not ...

In order to enhance interoperability and productivity in the development of situation-aware applications for disaster management, proper mechanisms and guidelines are required. They must address the lack of semantics in modelling emergency situations. In addition, the ever-changing and unpredictable nature of disaster scenarios present challenges for information processing and collaboration. Th...
