It generates the solution in the form of encoded binary chromosome using operators inspired by a natural evolution process: selection, crossover and mutation. In this paper, a hybrid genetic algorithm is applied to the emission probability estimation task of a continuous Hidden Markov Model which is one of the common optimization problems in speech recognition. Three backbone operators of the genetic algorithm are investigated in order to find the optimal Gaussian parameters that result in the best mixture model.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126262134","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, connection-based communications may impede progress towards IE scenarios involving high mobility or massive amounts of sensor nodes. We present a novel approach based on collective transmission for item level tagging using printed organic electronics, which implements robust, collective, approximate read-out of large numbers of simple tags. Our approach uses mechanisms for calculation by simultaneous transmission. We detail the collective transmission approach, discuss its implementation in the organic printed label scenario, and show first results of experiments conducted with our smart label test bed. We conclude with an outlook on the potential of collective transmission, and argue that collective transmission is a fundamental building block for realizing distributed intelligence.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128900600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Many of such devices have been developed to improve quality of life, and furthermore, to engage the end users with a richer environment by using multiple sensing technologies, such as GPS, brightness and gravity sensors. Unlike many desktop applications, context-aware devices have usually been used to offer always-on services to end users. In addition to taking advantage of context-awareness, a number of variables involved in highly dynamic environments also bring new challenges to Human-Computer Interaction design for such devices. One important concept of context-awareness is to improve the user experience by utilizing the resources available in the physical environment. Many context-aware devices use automated methods to generate the Quality of Service measurement for alternative reconfiguration when a change in the context occur but is that still competent when subjective issues are considered? This research takes a user experience perspective, which focuses on basic needs fulfillment and user preferences. The aim of this research is to clarify the relationship between users' motivations and preferences within alternative context-aware adaption, in order to help the designers improve the subjective user experience.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131673415","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These goals describe the desired state of the world. All behaviours create their goals solely based on the current state of the world, and independent of other behaviours. The created goals are then merged and a sequence of device actions is computed that lead to the desired state of the world.

One approach to solving this problem is the employment of human behaviour models, such as CTML and PDDL. At present, most of these models are based on concrete domains or scenarios which makes them difficult or impossible to adapt for other use cases. To overcome this drawback, this paper introduces an approach that uses partial order planning for generating a user behaviour model. Furthermore, it proposes a generalization of human activities by introducing atomic action templates valid for activities from various domains. To illustrate the approach, a scenario from the elderly care domain is modelled. Overall, the paper provides an effective general approach for modelling human behaviour which can be embedded in the intention inference workflow.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126537835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Before the city's rehabilitation the platform produces virtual images of the city based on the interaction of its inhabitants' local desires with a framework of global qualitative constraints. This process allows for the active recording of a new collective memory over the city's fabric and provides a tool for negotiation and conflict resolution. After the beginning of the rehabilitation process the platform is used as a tool for the design of the city's growth and change. Apart from the development of a site-specific narration dealing with the problem of Famagusta's rehabilitation, this paper's ambition is to contribute to a broader discussion on the character of parametric urbanism as well as to provide a potentially generalizable diagram for computer aided participation in contested spaces.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133630802","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is assumed that this ownership provides the children with the opportunity to establish and maintain social connections with their fellow peers. According to Vygotsky's Social Development Theory([21]) this social interaction with peers plays a role in children's cognitive development that has been exploited in modern educational systems in various ways. This ongoing research aims to make further use of this association between ownership of mobile devices, social nteraction and learning by ultimately introducing a technological solution for children to communicate with their peers and access peer generated content. It will investigate whether the mobility and the information source, peer versus non-peer, enhances children's learning. Two separate investigations have been conducted, so far, to determine the sources and the tools children use to obtain support for their learning. A survey of 74 Key Stage 3 children and two focus group sessions with 34 similar age children found that they actively use technologies, such as Face book, SMS and email, to establish peer interaction.","PeriodicalId":207140,"journal":{"name":"2011 Seventh International Conference on Intelligent Environments","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124239208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A number of such systems have been proposed, with claims of fall detection accuracy of over 90% based on accelerometers and gyroscopes. However, most such fall detection algorithms have been developed based on observational analysis of the data gathered, leading to thresholds setting for fall/non-fall situations. Whilst the fall detection accuracies reported appear to be high, there is little evidence that the threshold based methods proposed generalise well with different subjects and different data gathering strategies or experimental scenarios. Moreover, few attempts appear to have been made to validate the proposed methods in real-life scenarios or to deliver robust fall decisions in real-time. The research here uses machine learning and particularly decision trees to detect 4 types of falls (forward, backward, right and left). When applied to experimental data from 8 male subjects, the accelerometers and gyroscopes based system discriminates between activities of daily living (ADLs) and falls with a precision of 81% and recall of 92%.
