CeRC Story-Game Engine: An open source technology to power story based investigation games
Playing computer games is widely popular among children
and teenagers as an entertainment activity; however computer games can also be easily transformed into tools for education. City University London’s City eHealth Research Centre (CeRC) - has developed such educational computer games to improve young people’s understanding
of the importance of hand and respiratory hygiene and responsible antibiotic use; and to teach school syllabus concepts such as microbes, the spread and prevention of infection, antibiotic use and antibiotic resistance. We have developed a game platform as an open-source
framework to promote game development for education and
entertainment. The platform enables the efficient development of new games with new learning objectives along with the ability to support
translation into any language. For example, the current CeRC games have been translated into 11 European languages (English, BelgianFrench, Flemish, Czech, Danish, French, Greek, Italian, Polish, Portuguese, and Spanish). The existing CeRC games are targeted
towards school children; however, we investigate the usability of utilizing such games for adult education as well as examining the effectiveness of these games to convey messages to particular academic, industrial (or otherwise) communities

Evaluation of Popularity of Multi-lingual Educational Web Games – Do All Children Speak English?
Playing computer games is widely popular among children and teenagers as an entertainment activity; however, computer games can also be easily
transformed into tools for education. City University London’s City eHealth
Research Centre (CeRC) has developed such educational web games as a part
of a European Project, e-Bug (www.e-bug.eu) to improve pupils understanding
of the importance of hand and respiratory hygiene and responsible antibiotic
use. This paper studies the usage of the Games between January 2009 and
March 2010, specifically for 10 European Union countries. The Games were
first provided in English-only and it was found that over half of the users were
from non-UK countries. Once the Games were translated into multiple
European languages, it was found that users preferred to play the Games in their
native tongue. Thus, English was not a hindrance to Game playing/access;
however, the option of using another language was always taken once provided.
Users found the website through search engines and direct links from schools
and other websites, and over 60,000 visitors played the Games at least once.
The quantitative data used to investigate our research questions stemmed from
the Games website server logs
Understanding the relevance of in-mouth food processing. A review of in vitro techniques
[EN] Oral processing of food is the first step in the eating process. Although the food undergoes a number of changes during mastication that influence the subsequent steps, this stage has very often been neglected in studies of digestion, bioavailability, flavor release, satiety potential, glycemic index determination, etc. The present review draws on different sources such as nutrition, medicine, phoniatry and dentistry to explain some in vitro oral processing methods and techniques that could be transferred to food technology studies to mimic in vivo comminution, insalivation, and bolus formation, describing, as a necessary reference, the respective in vivo physiological processes they attempt to imitate.
Developing a deeper understanding of all the aspects of in-mouth process will help food technologists to give this crucial step the necessary attention its due importance and to consider better ways to incorporate it into their studies.The authors wish to acknowledge the financial support of the Spanish Government (project AGL2012-36753-C02) and gratefully acknowledge the financial support of EU FEDER funds.

Investigation of breathing-disordered sleep quantification using the oxygen saturation signal
This thesis investigates the feasibility of using the non-invasive biomedical signal of oxygen saturation, or SpO2 , to diagnose a sleep disorder known as Obstructive Sleep Apnoea Hypopnoea Syndrome (OSAHS). Epidemiologically, OSAHS is the most common condition investigated by sleep clinics. In a patient suspected of having the disorder, the upper airway is obstructed during sleep and a cessation in respiration results. An apnoea is defined as a temporary cessation of breathing. Similarly, a hypopnoea is defined as any reduction in breathing (i.e., less severe than an apnoea). The work has three main objectives; the first being to establish automated evaluation procedures for methods of quantifying apnoeic activity from the SpO2 signal, the second being to accurately identify apnoeic and normal activity on a minute-by-minute basis, the third being to create a Respiratory Disturbance Index (RDI) based on the analysis which is comparable to the gold-standard Apnoea Hypopnoea Index (AHI) derived by experts. The detection of apnoeic activity is determined using three separate analyses: time domain, frequency domain, and autoregressive modelling with an incorporated amplitude criterion. A training dataset is utilised for algorithm development, and an independent dataset is employed for testing . All three methods result in comparable overall classification accuracies of: 81.2% (time domain), 82.1% (frequency domain), and 80.0% (autoregressive modelling with amplitude). In addition, particular attention is given to the resultant sensitivity, specificity, and accuracy values partitioned according to patient category; i.e., patients with OSAHS may be divided into normal, mild, moderate and severe. Lastly, a simple RDI is computed based on the automated analyses; i.e., the number of apnoeic segments detected divided by the total number of segments used. A comparison between computed RDI and AHI values for the test database show correlation values above 0.8. In conclusion, this thesis shows that through the automated analysis of the SpO2 signal, OSAHS severity in patients suspected of having the disorder can be quantified. The AR-modelling with an incorporated amplitude criterion, in particular, shows the most promise for further work in this area.</p
