Pervasive systems must offer an open, extensible, and evolving portfolio of services which
integrate sensor data from a diverse range of sources. The core challenge is to provide …

Development of context-aware applications is inherently complex. These applications adapt
to changing context information: physical context, computational context, and user …

In pervasive and ubiquitous computing systems, human activity recognition has immense
potential in a large number of application domains. Current activity recognition techniques (i) …

This paper presents a qualitative study of role changes that occur when faculty becomes
virtual professors. In 20 semi-structured interviews of faculty, coded with pattern analysis …

Developing ubiquitous applications is particularly complex. Beyond the dynamic aspect of
such applications, the evolution of computing towards the multiplication of mobile access …

Context-aware pervasive systems are an important emerging category of software,
increasingly pervading into daily life, play and work. These systems are characterized by …

Pervasive computing is typically highly sensor-driven, but sensors provide only evidence of
fact rather than facts themselves. The uncertainty of sensor data will affect each component …

Negotiation is a collaborative activity that requires the participation of different parties whose
behaviors influence the outcome of the whole process. The work presented here focuses on …

Highly sensorised systems present two parallel challenges: how to design a sensor suite
that can efficiently and cost-effectively support the needs of given services; and to extract the …

Working collaboratively is no longer an issue but a reality, what matters today is how to
implement collaboration so that it is as successful as possible. However, successful …
