Activity recognition using temporal evidence theory

McKeever, Susan ; Ye, Juan ; Coyle, Lorcan ; Bleakley, Chris ; Dobson, Simon (IOS Press, 2010)

The ability to identify the behavior of people in a home is at the core of Smart Home functionality. Such environments are equipped with sensors that unobtrusively capture information about the occupants. Reasoning mechanisms ...
Adaptive management of shared resource pools with decentralized optimization and epidemics

Loureiro, Emerson ; Nixon, Paddy ; Dobson, Simon (IEEE, 2010-02-19)

Shared resource pools are facilities featuring a certain amount of resources which can be used by different applications. For managing resources in such pools, the demand of each application can be used. Such a demand, ...
From physical models to well-founded control

Dobson, Simon ; Coyle, Lorcan ; O'Hare, G. M. P. (Greg M. P.) ; Hinchey, Mike (IEEE Press, 2009)

Mobile sensors are an attractive proposition for environmental sensing, but pose significant engineering problems. Not least amongst these is the need to match the behaviour of the sensor platform to the physical environment ...
Implicit interaction : a prerequisite for practical AmI

O'Grady, Michael J. ; O'Hare, G. M. P. (Greg M. P.) ; Dobson, Simon ; Tynan, Richard ; Muldoon, Conor ; Ye, Juan (2009-06)

Intelligent User Interfaces represent one of the three distinguishing characteristics of AmI environments. Such interfaces are envisaged as mediating between the services available in an arbitrary physical environment and ...
Ontology-based query recommendation as a support to image retrieval

Murdoch, Olga ; Coyle, Lorcan ; Dobson, Simon (2008-08)

Stock photo libraries are the most common means for publishers and advertisers to find images for their media. Searching for the perfect photo can be a time-consuming and frustrating task. This is because searching is ...
Ontonym : a collection of upper ontologies for developing pervasive systems

Stevenson, Graeme ; Knox, Stephen ; Dobson, Simon ; Nixon, Paddy (ACM, 2009-04)

Pervasive systems present the need to interpret large quantities of data from many sources. Context models support developers working with such data by providing a shared representation of the environment on which to base ...
PI : perceiver and interpreter of smart home datasets

Ye, Juan ; Stevenson, Graeme ; Dobson, Simon ; O'Grady, Michael J. ; O'Hare, G. M. P. (Greg M. P.) (IEEE, 2011-05-23)

Pervasive healthcare systems facilitate various aspects of research including sensor technology, software technology, artificial intelligence and human-computer interaction. Researchers can often benefit from access to ...
Robust High Accuracy Ultrasonic Range Measurement System

Saad, Mohamed M. ; Bleakley, Chris ; Dobson, Simon (IEEE, 2011-10)

This paper presents a novel method for ultrasonic range estimation. The method uses a wideband frequency-hop spread spectrum ultrasonic signal to increase robustness to noise and reverberation. The method applies ...
Using situation lattices in sensor analysis

Ye, Juan ; Coyle, Lorcan ; Dobson, Simon ; Nixon, Paddy (IEEE Press, 2009)

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 semantically relevant interpretations, ...
