GPS receiver performance can suffer in difficult environments such as urban canyons and heavy foliage. Inertial sensors provide information between GPS updates and can enhance the position solution in a GPS/INS architecture. Additional information from safety sensors already on the vehicle, such as lane departure warning (LDW) sensors, can enhance the navigation solution further by constraining inertial...
This paper addresses the issue of the creation of context-aware applications inside the Mobile-Learning approach. It tries to clarify aspects like the most suitable environments of application; how new features of mobile devices, such as GPS (Global Positioning System) receivers, motion sensors, etc., must be taken into account. It also addresses why most of the m-Learning applications do not make...
The way people learn out of university has much more in common with self-learning and problems-guided learning than with the classical way of teaching, with a teacher speaking in a class and all the students listening with a passive attitude. This paper proposes an exercise to motivate students to learn and use some advanced programming concepts such as the use of well-formed and valid XML documents;...
Location tracking systems are becoming more relevant in many new environments, due to the fact they are the core of context aware applications. This new concept can improve the way organizations provide services and do business. Inside university area, users location (both students, teachers and staff) gives rise to a new kind of services based on their profile and on the area in which the user is...
Data have been collected from two dolphins engaged in free-swimming, bottom-object searches in conjuction with the deployment of both the BMT and IMS systems. Preliminary results demonstrate distinctive search strategies between the animals. The instrumentation described herein has been designed to provide quantitative data for free-swimming dolphins conducting mine-hunting tasks. The data allow researchers...
