Crime prediction based on traditional socio-demographic data is of limited value because it fails to capture the complexity and dynamicity of human activity in cities. With the rise of ubiquitous computing, there is the opportunity to improve crime prediction models with crowdsourced data that make for better proxies of human activity. In this paper, we propose the use of Foursquare data for cr...

Ubiquitous monitoring of distributed infrastructures

For unknown reasons, research into ubiquitous computing seems to pay no attention to collaboration among users in such an environment. This paper presents the design philosophy of activity-based computing (abc) and a technical implementation of it in a ubiquitous computing infrastructure, the ABC framework, which takes collaboration in ubiquitous environments as its starting point. The idea of ...

A large-scale of civil infrastructure systems is associated with great amounts of project resources and activities interoperated with various participants and organizations. Well-defined methodology for information acquisition and communication became more critical in the management of civil infrastructure than ever before. Rapidly emerging wireless sensor technology has been drawing a log of a...

Recent advances in ubiquitous computing are turning our environments into smart spaces, where technology is embedded into the physical environment. Significant levels of data must be constantly and ubiquitously collected to provide much of the new functionality; a process we refer to as ubiquitous monitoring. Existing research has shown that monitoring can often cause undesirable effects, such ...

Wireless sensor networks (WSNs) enable smart environments to create pervasive and ubiquitous applications, which give context-aware and scalable services to the end users. In this paper, we propose an architecture and design of a web application for a sensor network monitoring. Further, the variation in received signal strength indicator values is used for knowledge extraction. Experiments are ...
