Abstract:

A vessel is a qualitatively complex movable object, which motion can easily predicted when proceeding in unchanged navigation conditions. When navigation conditions become more difficult prediction of vessel requires the implementation of a complex set of actions to assess the position and parameters of the vessel’s motion relative to the limits and directions of the waterway. Lock approaches are characterized by significantly congested conditions and variable dimensions, tortuosity of the waterway, and spatial navigational hazards of complex form, to indicate which floating and land marks are

Navigational information is of great significance to the safety of maritime navigation. To better guarantee navigator safety and improve navigation efficiency, an applied model of geographic information services (GI services) that consists of an operational architecture, several subsystems and multiple GI services is presented.

Abstract:

The review study focuses on piloting vessels on inland waterways that presents persistent challenges due to the influence of variable external factors on vessel passage. Under such conditions, a navigator must possess a clear understanding of the vessel's present state and anticipate its behavior over a predictive time horizon. Therefore, expertise in ship handling is critically important not only for navigating particularly challenging routes but also for routes where extremely low water levels necessitate a reduction in the ship’s maximum draught and require minimal ship speed. Routes affect

Abstract:

The paper discusses the challenges of navigating vessels in narrow waters, where the presence of shoals, shallow areas, and intensive traffic significantly increases the risk of navigational hazards. Errors in navigation measurements and maneuvering further contribute to collision and grounding risks. In such conditions, the navigator forms a mental model that integrates information about the vessel’s position, planned route, surrounding hazards, moving objects, and navigational aids. This complex and often overwhelming flow of information may exceed the navigator’s cognitive capacity, leading

Abstract One of the most important concepts concerning the safety of navigation is the ship domain. The maritime domain is one of the oldest domains, which preceded the ones used in aviation, railway industry, chemical industry and medical. Through the concept of a ship domain is to be understood a certain area around the vessel, which the navigator wants to keep free of other fixed and moving objects. Navigational situation can be considered safe as long as no other ship neither any navigational obstacle would not exceed the area. In order to build and develop methods to assess the safety of

Navigation occurs through a continuum of space and time. The hippocampus is known to encode the immediate position of moving animals.

This spatiotemporal representation extends both forward and backward in time, with an emphasis on future locations

We conducted a qualitative meta-synthesis of client experiences with HIV patient navigation. Data were analyzed using thematic synthesis. We identified seven relevant studies; all collected data via in-depth interviews with persons with HIV who participated in HIV patient navigation. Four interrelated themes emerged from analysis that pertain to (1) the complexity of

Abstract:

The global maritime digitalization reflects on navigation and paperless vessels with Paper Navigational Charts (PNC) nowadays superseded by Electronic Chart Display and Information System (ECDIS). Considering the system implementation and its acceptance as a sole navigational means, opinions of navigators differ. Although the ECDIS mandatory implementation ended in 2018, some navigators have been still favouring PNCs, pointing out their advantages over ECDIS navigation. These standpoints may have an impact on the safety of navigation in terms of acceptance, interpretation, and understanding of

Abstract:

Abstract In the 21st century marine navigation has become dominated by satellite positioning systems and automated navigational processes. Today, global navigation satellite systems (GNSS) play a central role in the process of carrying out basic navigational tasks, e.g. determining the coordinates of a vessel’s position at sea. Since satellite systems are being used increasingly more often in everyday life, the signals they send are becoming more and more prone to jamming. Therefore there is a need to search for other positioning systems and methods that would be as accurate and fast as the ex

Abstract:

There is considerable research on the neurobiological mechanisms within the hippocampal system that support spatial navigation. In this article I review the literature on navigational strategies in humans and animals, observations on hippocampal function in navigation, and studies of hippocampal neural activity in animals and humans performing different navigational tasks and tests of memory. Whereas the hippocampus is essential to spatial navigation via a cognitive map, its role derives from the relational organization and flexibility of cognitive maps and not from a selective role in the spa

Navigating in unfamiliar road environments is a common and demanding cognitive activity. If this cannot be accomplished successfully, there are implications for increased driver workload, delays due to navigation errors, potentially unsafe road behaviour such as late lane changes, and inappropriate traffic management. To enable successful navigation through such environments, it is necessary to understand what the navigation task entails, and what a driver's corresponding information requirements are.
