With regard to a marine safety system, large vessels are generally loaded with INS (Integrated Navigation System). But although small and medium-sized ships are exposed to safety accidents in the sea, they are not carrying proper navigation devices and equipment. Accordingly, in order to develop INS for small and medium-sized ships(s-INS), an existing INS has newly been organized and integrated...

This work deals with the problem of navigation while avoiding detection by a mobile adversary, which is a novel variant of pursuit-evasion featuring adversarial modeling. In this problem, an evading agent is placed on a graph, where one or more nodes are defined as safehouses. The agent’s goal is to find a path from its current location to a safehouse, while minimizing the probability of meetin...

Scientific facilities usually require the use of vehicles controlled remotely by an operator relying on the information provided by a camera. However, the operator lacks of depth perception, which makes difficult the navigation. Providing additional information by means of Augmented Reality (AR) may enhance the safety and accuracy of the navigation. AR has been used in outdoor navigation system...

Satellite-based location and timing systems support a wide range of mass market applications, typically using the GPS infrastructure. Until recently, these applications could not be used within safety-critical interfaces. Limits to the accuracy, availability, integrity and continuity of the space-based signals prevented regulatory agencies from certifying their use. Over the last three months, ...

Safety culture is broadly recognized as important for operational safety in various fields, including air traffic management, power plant control and health care. Previous studies addressed characterization and assessment of safety culture extensively. Nevertheless, relations between safety culture and formal and informal organizational structures and processes are yet not well understood. To a...
