The development of unit root tests continues unabated, with many recent contributions using techniques such as generalized least squares (GLS) detrending and recursive detrending to improve the power of the test. In this article, the relation between the seemingly disparate tests is demonstrated by algebraically nesting all of them as ratios of quadratic forms in normal variables. By...

In 3D virtual environments (3DVE), we need to know what an object looks like (i.e. geometric information) and what the object is, what are its properties and characteristics and how it relates to other objects (i.e. non-geometric information). Several interactive presentation techniques have been devised to incorporate non-geometric information into 3DVEs. The relevance of a...

We propose a collaborative training platform where students collectively contribute to the co-construction of the required knowledge to produce their individual semester project. Peers feedback is implemented in order to complete trainers' supervision with peer-training. This collaborative platform is implemented as a social network, where collaborative interactions are...

We define 'SPEM fragments' of five methods for developing self-organising multi-agent systems. Self-organising traffic lights controllers provide an application scenario.

The emergence of high bandwidth public wireless networks and miniaturized personal mobile devices give rise to new mobile healthcare services. To this end, the MobiHealth system provides highly customizable vital signs tele-monitoring and tele-treatment system based on a body area network (BAN) and a mobile health care (m-health) service platform utilizing next generation public...

The term Serious Games has been used to describe computer and video games used as educational technology or as a vehicle for presenting or promoting a point of view. Serious games can be of any genre and many of them can be considered a kind of edutainment. Serious games are intended to provide an engaging, self-reinforcing context in which to motivate and educate the players towards...

Mobile service providers (MoSPs) emerge, propelled by ubiquitous availability of mobile devices and wireless communication infrastructures. MoSPs' customers satisfaction and consequently their revenues, largely depend on the quality of service (QoS) offered by wireless network providers (WNPs) at a particular location and time of a mobile service usage. This chapter presents a...
