Autonomous robot navigation with the capability to perceive the surrounding environment of the robot enhances the efficiency and safety of the robot. A technique for terrain classification for traversability assessment of mobile robot navigating in natural terrain by extracting the textural features from visual sensing of terrain data using co-occurrence matrix is presented in this paper. The a...

This article investigates the possibility of optimizing the organization of a ship as a highly complex technical system. In this sense, the existing relationship between technology and the human as a user is considered. Using the sociotechnical approach the aim is to identify the weaknesses in the existing technological and organizational ship’s system. Based on research conducted on the naviga...

Navigation system improves the accuracy of the surgical procedures. A CT-free intraoperative planning and navigation system, based on SurgiGate system (PraximMedivision, La Tronche, France), has been developed for high tibial dome osteotomy. High tibial dome osteotomy is technically demanding procedure with, common complication such as postoperative malalignment or pin penetration of the tibial...

In this paper we explore which bundles of services are attractive to users. We look specifically into bundle composition with navigation services as core, and travel and entertainment related services as complementary services. Pricing is an important criterion as well. We use conjoint measurement as a tool to assess which combination of services and price is the most attractive for users. We f...

The positioning system based on satellite navigation can meet the requirements of CTCS-4 train control, improve transportation efficiency, reduce operation and maintenance costs, which is trend in future, security risk assessment great significance to future application this system. In paper, combined with self-developed navigation, an improved fault tree-interval analytic hierarchy process (FT...

Modern safety-critical organizations are characterized by complex, nonlinear dynamics involving many interrelated actors and processes. Safety issues that emerge from these complex dynamics increasingly remain hidden, until an incident or even a serious accident occurs. Traditional safety analysis methods developed long ago for much simpler organizations cannot help identifying, explaining and ...

Safety culture is broadly recognized as important for Air Traffic Management and various studies have addressed its characterization and assessment. Nevertheless, relations between safety culture and formal and informal organizational structures and processes are yet not well understood. We aim to improve the understanding of these relations by agent-based organizational modelling and thus prov...

Accurate and reliable relative navigation is the prerequisite to guarantee effectiveness safety of various multiple Unmanned Aerial Vehicles (UAVs) cooperation tasks, when absolute position information unavailable or inaccurate. Among UAV techniques, Global Navigation Satellite System (GNSS) widely used due its worldwide coverage simplicity in navigation. However, observations GNSS are vulnerab...

Operational safety and health monitoring are critical matters for autonomous field mobile robots such as planetary rovers operating on challenging terrain. This paper describes relevant rover safety and health issues and presents an approach to maintaining vehicle safety in a navigational context. The proposed rover safety module is composed of two distinct components: safe attitude (pitch and ...

Navigating a new route during automobile driving uses the driver's cognitive resources and has the potential to impair driving ability in people with Parkinson's disease (PD). Our aim was to assess navigation and safety errors during a route following task (RFT) in drivers with the illness. Seventy-seven subjects with mild-moderate PD (median Hoehn-Yahr stage = 2.0) and 152 neurologically norma...
