This paper proposes a Distributed Vision System as a Perceptual Information Infrastructure for robot navigation in a dynamically changing world. The distributed vision system, consisting of vision agents connected with a computer network, monitors the environment, maintains the environment models, and actively provides various information for the robots by organizing communication between the v...

Information and communication technology (ICT) and systems are essential for every business. They can be used in retail, manufacturing and other industries. Nevertheless, new and innovative ideas and solutions are constantly emerging and introducing new possibilities for the reorganization of traditional logistics processes.

Object caching is a desirable feature to improve the both scalability and performance of distributed application systems for information infrastructure, the information management system leveraging the power of network computing. However, in order to exploit such benefits, we claim that the following problems: cache server placement, cache replacement, and cache synchronization, should be consi...

Climate change is a growing concern to humankind, since the dominant view argues for rapid, significant changes in human behavior to avert catastrophic consequences. This is a complex problem, known as a wicked problem. A productive way forward is through creative, critical dialogue. Such dialogue requires new kinds of sociotechnical infrastructure. We offer a socio-technical infrastructure, de...

Spatial technologies are evolving quickly, particularly with regard to land related data. The design of land information system needs to be efficiently comprehensive to take these into account and manage them through a Spatial Data Infrastructure (SDI). The most effective management with the technological trends is likely to lie in spatial enablement of the various sets of information. SDIs aim...
