This paper discusses the agent based mobility management functionality developed by the ACTS-340MARINE project. MARINE’s mobility management procedures are based on mobile agent and distributed processing technology. The MARINE service, Broadband Video Telephony, is introduced as a scenario for the MARINE mobility management procedures. Three approaches for User Assistant agents to support user...

We are experiencing the expanding use of location-based services such as AT&T TeleNav GPS Navigator and Intel’s Thing Finder. Existing location-based services have collected a large amount of location data, which have great potential for statistical usage in applications like traffic flow analysis, infrastructure planning and advertisement dissemination. The key challenge is how to wisely use t...

Do children spontaneously represent spatial-numeric features of a task, even when it does not include printed numbers (Mix et al., 2016)? Sixty first grade students completed a novel spatial estimation task by seeking and finding pages in a 100-page book without printed page numbers. Children were shown pages 1 through 6 and 100, and then were asked, "Can you find page X?" Children's precision ...

The Relationship Finder is a tool for exploring connections between objects in a Semantic Web knowledge base. It offers a new way to get insights about elements in an ontology, in particular for large amounts of instance data. For this reason, we applied the idea to the DBpedia data set, which contains an enormous amount of knowledge extracted from Wikipedia. We describe the workings of the Rel...

Cognitive behaviorist E. C. Tolman (1932) proposed many years ago that rats and men navigate with the aid of cognitive maps, but his theory was incomplete. Critic E. R. Guthrie (1935) pointed out that Tolman's maps lack a rule for action, a route finder. We show that a dynamic model for stimulus generalization based on an elementary diffusion process can reproduce the qualitative properties of ...

Probabilistic inference will be of special importance when one needs to know how much we can say with what all we know given new observations. Bayesian Network is a graphical probabilistic model with which one can represent probabilistic relations intuitively and several effective algorithms for inference are developed. This paper reports a now ongoing work in its design stage which provides a ...

Abstract With the rapid development of tourism in economy, popular demand for also increases. Unreasonable distribution arises a series problems such as reduction tourist satisfaction and decrease income attractions. Based on consideration route planning, mathematical model which takes maximization overall all groups objective function is established by taking age preferences tourists, upper li...
