Although GPS measurements are the essential information for currently developed land vehicle navigation systems (LVNS), the situation when GPS signals are unavailable or unreliable due to signal blockages must be compensated to provide continuous navigation solutions. In order to overcome the unavailability or unreliability problem in satellite based navigation systems and also to be cost effec...

Refugee/asylee: A person who, because of a well-founded fear of persecution on account of race, religion, nationality, membership in a particular social group, or political opinion, is forced to flee the country of his or her nationality and is unwilling or unable to seek the protection of his or her government. Refugee status is determined by Immigration and Naturalization Service (INS) before...

Teams of humans and robots working together can provide effective solutions to problems. In such applications, effective human-robot teaming relies on being able to communicate information about the current perception or understanding of the environment. In this paper, human-robot teaming on navigational tasks is discussed. The role of the human user will be to specify the goal point(s) for the...

The designing of advanced driver assistance systems and autonomous vehicles needs measurement of dynamical variations of vehicle, such as acceleration, velocity and yaw rate. Designed adaptive controllers to control lateral and longitudinal vehicle dynamics are based on the measured variables. Inertial MEMS-based sensors have some benefits including low price and low consumption that make them ...

In this paper a biologically inspired approach for compensating the limited angle of vision in obstacle detection systems of mobile robots is presented. Most of the time it is not feasible to exhaustively monitor the environment of a mobile robot. In order to nonetheless achieve safe navigation obstacle detection mechanisms need to keep in mind certain aspects of the environment. In mammals thi...

In some circumstances the erosive effects of inertial (transient) cavitation have been usefully employed in the acceleration of chemical processes that are dependent on surface reactions. However, in other situations the erosion of materials can be detrimental. For example erosion/corrosion phenomena have been well documented. It will be demonstrated here that the employment of inertial cavitat...

This paper presents a monocular vision framework enabling feature-oriented appearance-based navigation in large outdoor environments containing other moving objects. The framework is based on a hybrid topological-geometrical environment representation, constructed from a learning sequence acquired during a robot motion under human control. The framework achieves the desired navigation functiona...

AT&T participated in two tasks at TRECVID 2010: contentbased copy detection (CCD) and instance-based search (INS). The CCD system developed for TRECVID 2009 was enhanced for efficiency and scale and was augmented by audio features [1]. As a pilot task, participation in INS was meant to evaluate a number of algorithms traditionally used for search in a fully automated setting. In this paper, we ...
