Bluefin’s business focus is the design and manufacture of autonomous underwater vehicles for use in military, scientific, and commercial applications. For many AUV missions, accurate navigation that does not depend on acoustic beacons in the operating region is one of the primary remaining technical hurdles. This effort will address this need through the creation of the Cornerstone AUV Navigato...

Abstract This article furthers understanding of the value experiential knowledge for social policy and practice. It draws on new empirical material to critically explore opportunities challenges inherent in lived experience support work with multiply disadvantaged adults. Reflecting experiences those delivering a ‘navigator’ service, particular attention is paid an ambiguity around ways which m...

In this paper we propose and demonstrate a simple method for navigation in a large unstructured environment that contains featureless objects, which uses \isolated" landmarks in the navigator's view. The map-maker and navigator are implemented using an IBM 7575 SCARA robot arm, the PIPE (Pipelined Image Processing Engine), and two cameras. The navigational environment consists of a at plane wit...

Browsers: The programs which interpret pages of HTML and display them to the user. Many different browsers exist, but increasingly, web pages are specifically designed with two browsers in mind: Netscape Navigator and Microsoft Internet Explorer. Versions of Netscape Navigator since 2.0 support many extra features, such as ‘plug-in’ helper applications, integrated e-mail and news reading, and S...

This paper describes a self-learning navigation method which utilizes fuzzy logic and reinforcement learning for navigation of a mobile vehicle in uncertain environments. The proposed navigator consists of three modules: Obstacle Avoidance, Move to Goal and Fuzzy Behavior Supervisor. The fuzzy rules of the on-line obstacle avoidance are learnt through reinforcement learning. A new and powerful ...

The simultaneous multiple volume (SMV) approach in navigator-gated MRI allows the use of the whole motion range or the entire scan time for the reconstruction of final images by simultaneously acquiring different image volumes at different motion states. The motion tolerance range for each volume is kept small, thus SMV substantially increases the scan efficiency of navigator methods while main...
