Since most persons in emergency service wear some sort of headgear, we investigate how basic navigation sensors could be incorporated into a safety helmet and thereby be made truly wearable. It is well known that the key to solving the generic ubiquitous localization problem is the combination of different positioning techniques and sensor modalities. In this paper, a combined approach of pedes...

BACKGROUND Detailed information about animal location and movement is often crucial in studies of natural behaviour and how animals respond to anthropogenic activities. Dead-reckoning can be used to infer such detailed information, but without additional positional data this method results in uncertainty that grows with time. Combining dead-reckoning with new Fastloc-GPS technology should provi...

We present a particle-based framework for estimating the position of a vehicle using map information and measurements of speed. Two measurement functions are considered. The first is based on the assumption that the lateral force on the vehicle does not exceed critical limits derived from physical constraints. The second is based on the assumption that the driver approaches a target speed deriv...

We extend a dynamic approach of behavior generation to the representation of spatial information. Two levels of dynamics integrate dead-reckoning, dominant far from home bases, and piloting, dominant near home bases. When the view-based piloting system recognizes a home base, visual place information re-calibrates the dead-reckoning system, inverting the hierarchical ordering of the two dynamic...

Cropcheck developed following the identification of limitations to the Transfer of Technology (TOT) extension model which occurred through the 1970’s and into the early 1980’s (Lacy 2011). Irrigated wheat yields stagnated with high variability from year to year and no understanding as to why this occurred. This was despite several communication methods (farm visits, demonstrations, plot trials,...

Biologically inspired models for navigation use mechanisms like path integration or sensori-motor learning. This paper describes the use of a proprioceptive working memory to give path integration the potential to store several goals. Then we coupled the path integration working memory to place cell sensori-motor learning to test the potential autonomy this gives to the robot. This navigation a...

Abstract This paper proposes a localization method to estimate position and azimuth of a lunar rover. In the proposed method, the position is precisely estimated by integration of an absolute and a relative position. The absolute position is measured by observing the Sun and the Earth, and the relative position is determined by the dead reckoning. Effectiveness is confirmed by the results of ex...

This paper presents a system of absolute localization based on the cooperation of a stereoscopic omnidirectional vision system and a dead-reckoning system. To do it we use an original perception system which allows our omnidirectional vision sensor SYCLOP to move along a rail. The first part of our study will deal with the problem of building the sensorial model with the help of the two stereos...

We propose a new method of self-localization using two landmarks and dead reckoning for a soccer robot equipped with an omnidirectional camera as a local vision sensor. This method requires low computational cost. Thanks to rapid process, the system can afford to run multiple localization process in parallel resulting robust and accurate localization. An experimental result in the field of Robo...

This paper presents an effective approach for resume information extraction to support automatic resume management and routing. A cascaded information extraction (IE) framework is designed. In the first pass, a resume is segmented into a consecutive blocks attached with labels indicating the information types. Then in the second pass, the detailed information, such as Name and Address, are iden...
