Shakra: tracking and sharing daily activity levels with unaugmented mobile phones

This paper explores the potential for use of an unaugmented commodity technology—the mobile phone—as a health promotion tool. We describe a prototype application that tracks the daily exercise activities of people, using an Artificial Neural Network (ANN) to analyse GSM cell signal strength and visibility to estimate a user’s movement. In a short-term study of the prototype that shared activity information amongst groups of friends, we found that awareness encouraged reflection on, and increased motivation for, daily activity. The study raised concerns regarding the reliability of ANN-facilitated activity detection in the ‘real world’. We describe some of the details of the pilot study and introduce a promising new approach to activity detection that has been developed in response to some of the issues raised by the pilot study, involving Hidden Markov Models (HMM), task modelling and unsupervised calibration. We conclude with our intended plans to develop the system further in order to carry out a longer-term clinical trial.

Increasing the Awareness of Daily Activity Levels with Pervasive Computing

Public health promotion technology should be accessible to the general public at which it is aimed. This paper explores the potential for use of an unaugmented commodity technology - the mobile phone - as a health promotion tool. We describe a prototype application that tracks the daily exercise activities of people carrying phones, using fluctuation in signal strength to estimate a users movement. In a short-term study of the prototype that shared activity information amongst groups of friends, we found that awareness encouraged reflection on, and increased motivation for, daily activity. We describe some of the details of the pilot study, and conclude with our intended plans to develop the system further in order to carry out a longer-term clinical trial

Constraining anomalous HVV interactions at proton and lepton colliders

In this paper, we study the extent to which CP parity of a Higgs boson, and more generally its anomalous couplings to gauge bosons, can be measured at the LHC and a future electron-positron collider. We consider several processes, including Higgs boson production in gluon and weak boson fusion and production of a Higgs boson in association with an electroweak gauge boson. We consider decays of a Higgs boson including
