Ubiquitous computing (or ambient intelligence) has been the subject of research in the mobile telecommunications field for many years. Developments such as the Internet of Services and Grid computing have complemented and strengthened this work. The ubiquitous computing paradigm integrates information processing into the objects that surround us in our environment. One particular focus has been...

TV White Spaces have recently been proposed as an alternative to alleviate the spectrum crunch, characterised by the need to reallocate frequency bands to accommodate the ever-growing demand for wireless communications. In this paper, we discuss the motivations and challenges for collecting spectrum measurements in developing regions and discuss a scalable system for communities to gather and p...

University campuses are busy places for wireless client traffic coming from Wi-Fi connections and other wireless devices that contend for the 2.4 GHz frequencies space that most campus Wi-Fi networks use currently. This is making the 2.4 GHz frequency unsuitable for WiFi connection due to too much interference from other devices as well as from Wi-Fi connections themselves. TV white space could...

Critical Discourse Analysis (CDA) is a multidisciplinary holistic, consisting of a number of different theoretical approaches to the microlevel analysis of text and talk that has to do with the social and/or political. These various methodological approaches are unified, however, by a macrolevel social critique which maintains that social inequality may be enacted, sustained and legitimised thr...

In practical Bayesian optimization, we must often search over structures with differing numbers of parameters. For instance, we may wish to search over neural network architectures with an unknown number of layers. To relate performance data gathered for different architectures, we define a new kernel for conditional parameter spaces that explicitly includes information about which parameters a...
