Terrorism is one of the most frequently used words in the media and the most effective political words of today. However, although there is a lot of talk about terrorism in the media as well as in the professional and scientific literature, it seems that this term remains insufficiently explained. When asked why this is so, the answer lies in a num...

Literature analysis has shown that the rationalization of the scenario process is mainly done by reducing the number of input factors, which greatly influences the scope of the output scenarios. The paper proposes the rationalization of the scenario process that is focused on the selection, validation, and classification of factors, but to involve...

The risk assessment process is based on risk management. Risk assessment is, in principle, an entirely empirical decision-making process, based on risk assessors’ knowledge and experience, necessary to identify (a) hazard(s) as the cause for risk by using specific and well-known and recognized methods so far. Currently, there are a large number of...

Robotic vehicles that are capable of autonomously transitioning between various terrains and fluids have received notable attention in the past decade due to their potential to navigate previously unexplored and/or unpredictable environments. Specifically, aerial-aquatic mobility will enable robots to operate in cluttered aquatic environments and c...

Over the past several decades, most regional and local conflicts have merely been the scenarios prepared in advance in the "kitchens" of great powers. The aforesaid scenarios are practically tested on simulation-based models that are formed as war games, which considerably save resources and improve the strategic and operational-tactical planning p...
