Inland navigation networks offer an alternative to land transport with economic and environmental benefits, and direct access to urban and industrial centers. Promoting the navigation transport requires the modernization of the network management, in particular the control of navigation levels and the improvement of the network safety. To reach these aims, modeling methods of the inland navigat...

Emergency navigation with a large number of sensors can serve as a safety service in emergencies. Recent studies have focused on navigation protocols to safely guide people to exits while helping them avoid hazardous areas. However, those approaches are not applicable in all circumstances. Both the dynamics of the environment and the mobility of users are key challenges for the efficiency and e...

AIMS We aimed to evaluate the safety and long-term efficacy of the magnetic navigation system (MNS) in a large number of patients. The MNS has the potential for improving safety and efficacy based on atraumatic catheter design and superior navigation capabilities. METHODS AND RESULTS In this study, 610 consecutive patients underwent ablation. Patients were divided into two age- and sex-matche...

The existence and enforcement of legal regulations is imperative of maritime navigation. All legal regulations relating to maritime security and whose goal is securing the safety at sea, can be divided to regulations relating to navigable vessels, regulations relating to cargo carried by ships; regulations governing maintenance of waterways; regulations relating to human factor (regulations con...

This study focused on the public transport risk assessment in District one of ​​Tehran through Fault Tree Analysis involving the three criteria of human, vehicle and road in Haddon matrix. In fact, it examined the factors contributing to the occurrence of road accidents at several urban black spots within District 1. Relying on road safety checklists and survey of experts, this study made an ef...

Physical rotations and translations are the basic constituents of navigation behavior, yet there is mixed evidence about their relative importance for complex navigation in virtual reality (VR). In the present experiment, 24 participants wore head-mounted displays and performed navigational search tasks with rotations/translations controlled by physical motion or joystick. As expected, physical...

The freedom of navigation in the South China Sea has drawn an extensive international concern in recent years. The main reasons leading to skepticism are the disputes in the South China Sea over islands sovereignty and maritime delimitation, extra-regional state’s intervention, and some ASEAN member states’ wish to countervail China with the help of extra-regional states. In fact there is no pr...

6 Cognitive impairments prevent older adults from using powered 7 wheelchairs due to safety concerns, thus reducing their mobility and 8 independence. An intelligent powered wheelchair is proposed to help 9 restore mobility, while ensuring safe navigation. Machine vision and 10 learning techniques are used to help prevent collisions with obstacles, as 11 well as provide navigation assistance th...

Percutaneous epicardial mapping and ablation is an emerging method to treat ventricular tachycardias (VT), premature ventricular complexes (PVC), and accessory pathways. The use of a remote magnetic navigation system (MNS) could enhance precision and maintain safety. This multiple case history demonstrates the feasibility and safety of the MNS-guided epicardial approach in mapping and ablation ...

Next generation Robotic Walker designers are investigating navigation functions to help the elderly and disabled people to remain healthier and stay socially active. However, unattended safety concern will highly likely led to a drop in users’ acceptance and organizational uptake of this technique. If safety remains to be a concern of both carers and users, this technique will possibly be at a ...
