    Full Text Available This study aims to predict the level of international tourists’ intention to use MTG in the context of Thai national parks, and investigates the roles of mobile design qualities (content quality, appearance quality, and interaction quality through perceived usefulness and perceived ease-of-use on intention. The mixed-method via exploratory sequential design is conducted this study. The qualitative approach is started in the first stage then quantitative approach is employed to analyze the large sample size. This study extends the TAM2 with mobile design qualities. The results shows the high level of international tourist’ intention to use MTG. It indicates that the international tourists will intent to the mobile tourism guide (MTG, if the MTG is provided for them. The direct factors of tourists’ intention are perceived usefulness, perceived ease-of-use, mobile content quality and mobile appearance quality. The most direct effect is mobile content quality. The qualities of content and appearance have the positive roles on perceived usefulness, while the qualities of appearance and interaction have the indirect effects through perceived ease-of-use on tourists’ intention. The proposed model provides the body of knowledge in the context of MTG, especially the factors of international tourists’ intention to use MTG.

There has been a developing realisation that mobilities do not ‘just happen.’ Mobilities are carefully and meticulously designed, planned and staged (from above). However, they are equally importantly acted out, performed and lived...... as people are ‘staging themselves’ (from below). Staging mobilities is a dynamic process between ‘being staged’ (for example, being stopped at traffic lights) and the ‘mobile staging’ of interacting individuals (negotiating a passage on the pavement).

    2012-05-01

    Full Text Available The purpose of this article is to undertand how the receptor might be affected in the consumption of contemporary cultural products, specifically, those works of art and design generated from digital media. Thus, the reading strategies previously proposed on the configuration of the objects studied were investigated, in order to understand how the different receptive practices were structured, considering the horizons of expectation which circumscribe the objects created from the use of mobile devices and decoding technology markers. First, you will see a discussion about these mobile media, and, second, a Peircean approach to rating and taking into account the forms of presentation of the objects studied. The paper classifies and rates these objects, assuming the dominance of interaction inherent to the poetic-technological proposals adopted.

  16. AWARE: mobile context instrumentation framework

    Directory of Open Access Journals (Sweden)

    Denzil eFerreira

    2015-04-01

    Full Text Available We present a mobile instrumentation toolkit, AWARE, an open-source effort to develop an extensible and reusable platform for capturing, inferring, and generating context on mobile devices. Mobile phones are sensor-rich but resource-constrained, and therefore several considerations need to be addressed when creating a research tool that ensures problem-free context collection. We demonstrate how AWARE can mitigate researchers’ effort when building mobile data-logging tools and context-aware applications, with minimal battery impact. By encapsulating implementation details of sensor data retrieval and exposing the sensed context as higher-level abstractions, AWARE shifts the focus from software development to data analysis, both quantitative and qualitative. We have evaluated AWARE in several case studies and discuss its use, power consumption, and scalability.

    2015-11-01

    Full Text Available Presenting a context-aware service and information is a key aspect of ubiquitous computing, but development of such applications is quite complicated. Context-aware applications should be able to obtain raw data fromsensors, create highlevel context information, detect the user’s situation, and adapt the behavior of the application to the recognized situation . These complexities caused to reduce the impact of context -awareness in mobile computing while sensors of smartphones have made huge potential for developing context aware mobile applications. In this paper, we explain some guidelines to overcome the existing obstacles by separating the context -aware application layers and make a loosely coupled connection between them. These guidelines will bring easy and rapid development, reusability of the code and flexibility for developers. Finally, we provide a case study example in the Android platform to demonstrate how the guidelines can be used in a real application.

  1. Towards an understanding of the virtual context in mobile learning

    Directory of Open Access Journals (Sweden)

    Sarah Cornelius

    2009-12-01

    Full Text Available Much of the literature theorising mobile learning emphasises the importance of context with physical and social contexts identified to date. Our work to design and implement authentic mobile simulation activities using SMS text messaging suggests that a third context may also be important. This is a virtual context, the learner-created cognitive space within which the activity takes place. The arrival of a message during a simulation activity will disrupt the real world physical and social contexts in which the learner finds themselves and transfer them into the virtual context. We argue that this disruptive power of the mobile device to shift the user's presence may be one of the distinguishing characteristics of certain mobile learning applications. This paper will explore the idea of the virtual context and discuss the role of issues of context, presence and disruption, illustrating these with reference to a case study of mobile simulation learning using SMS text messaging.

    With the development of wireless networks and mobile computing, more advanced applications with context-awareness and adaptability to their changing context are needed. However, building context-aware applications is difficult due to the lack of adequate infrastructure support. In this paper, a web middleware architecture for the development of context-awareness applications using near field communication (NFC) is proposed. Based on it, the efficient support for acquiring, interpreting, and accessing context is provided, and the user’s quality of experience is improved. Moreover, a mobile web middleware for the testing and full realization of NFC context-awareness applications has been developed together with two application examples.

To understand motivations for using a given communication device –as the mobile phone– we took into account the channels individual has access to; individual’s personal interest on using available devices in everyday communications; the location of the members of the individual’s personal network; and the pricing system that determines the cost of mediated communication. The empirical analysis is based on two case studies conducted in Romania and in the metropolitan area of Barcelona (Catalonia in different moments, between 2010 and 2012. Participants were 60 years old or over. Information was gathered by means of semi-structured interviews that were recorded and transcribed, while a common methodological design allows an enriched insight. Besides gender, we take into account heterogeneity of ageing for a more nuanced analysis. This paper constitutes the first step in the exploration of common trends in the relationship seniors have with mobile communication in different European countries.

    2009-01-01

    Full Text Available In a client-server mobile learning system, client mobile software must run on the mobile phone to acquire, package, and send student’s interaction data via the mobile communications network to the connected mobile application server. The server will receive and process the client data in order to offer appropriate content and learning activities. To develop the mobile learning systems there are a number of very important issues that must be addressed. Mobile phones have scarce computing resources. They consist of heterogeneous devices and use various mobile operating systems, they have limitations with their user/device interaction capabilities, high data communications cost, and must provide for device mobility and portability. In this paper we propose five principles for designing Client mobile learning software. A location-based adaptive mobile learning system is presented as a proof of concept to demonstrate the applicability of these design principles.

    Full Text Available In this study, a mobile cloud offloading system has been developed to decide that a process run on the cloud or on the mobile platform. A context-aware decision algorithm has been developed. The low performance and problem of battery consumption of mobile devices have been fundamental challenges on the mobile computing. To overcome this kind of challenges, recent advances towards mobile cloud computing propose a selective mobile-to-cloud offloading service by moving a mobile application from a slow mobile device to a fast server in the cloud during run time. Determine whether a process running on cloud or not is an important issue. Power consumption and time limits are vitally important for decision. In this study we used PowerTutor application which is a dynamic power measurement modelling tool. Another important factor is the process completion time. Calculate the power consumption is very difficult

    Science.gov (United States)

    Qureshi, Salim Raza

    2010-11-01

    Mobile computing environments are characterized by heterogeneity—systems consisting of different device types, operating systems, network interfaces, and communication protocols. Such heterogeneity calls for middleware that can adapt to different execution contexts, hide heterogeneity from applications, and transparently and dynamically switch between network and sensor technologies. Additionally, middleware for context-aware systems must keep a context model (a model of their environment), taking into account several aspects of the environment. The more complex and heterogeneous an execution environment is, the more complicated its underlying context model. Moreover, because systems can evolve, context management must also support model evolution without restarting, reconfiguring, or redeploying applications and services. We describe a context management middleware that can efficiently handle context despite the execution environment's heterogeneity and evolution. It uses context meta-information to improve a context-aware system's overall performance.

    2016-03-01

    Full Text Available Purpose: This study explores how search motivation and context influence mobile Web search behaviors. Design/methodology/approach: We studied 30 experienced mobile Web users via questionnaires, semi-structured interviews, and an online diary tool that participants used to record their daily search activities. SQLite Developer was used to extract data from the users' phone logs for correlation analysis in Statistical Product and Service Solutions (SPSS. Findings: One quarter of mobile search sessions were driven by two or more search motivations. It was especially difficult to distinguish curiosity from time killing in particular user reporting. Multi-dimensional contexts and motivations influenced mobile search behaviors, and among the context dimensions, gender, place, activities they engaged in while searching, task importance, portal, and interpersonal relations (whether accompanied or alone when searching correlated with each other. Research limitations: The sample was comprised entirely of college students, so our findings may not generalize to other populations. More participants and longer experimental duration will improve the accuracy and objectivity of the research. Practical implications: Motivation analysis and search context recognition can help mobile service providers design applications and services for particular mobile contexts and usages. Originality/value: Most current research focuses on specific contexts, such as studies on place, or other contextual influences on mobile search, and lacks a systematic analysis of mobile search context. Based on analysis of the impact of mobile search motivations and search context on search behaviors, we built a multi-dimensional model of mobile search behaviors.

    2012-10-01

    Full Text Available This research applied a mixed-method design to explore how best to promote learning in authentic contexts in an online graduate course in instructional message design. The students used Twitter apps on their mobile devices to collect, share, and comment on authentic design examples found in their daily lives. The data sources included tweets (i.e., postings on Twitter, students’ perceptions about mobile microblogging activities, and self-reported Twitter usage. Based on the tweet analysis, we found that the students appropriately applied the design principles and design terms in their critique of design examples. While the students were mainly engaged in assignment-relevant activities, they spontaneously generated social tweets as they related peers’ authentic design examples to their own life experiences. Overall, they had positive perceptions toward the mobile microblogging activities. The students also indicated that the design examples shared by peers through mobile microblogging inspired their own message design work. We synthesized instructional design suggestions and challenges for educators interested in incorporating mobile microblogging in their instructional settings.

    Daniele, Laura M.; Silva, Eduardo; Pires, Luís Ferreira; van Sinderen, Marten

    Context-aware mobile applications are intelligent applications that can monitor the user’s context and, in case of changes in this context, consequently adapt their behaviour in order to satisfy the user’s current needs or anticipate the user’s intentions. The design of such applications relies on dynamic middleware platforms that consist of a variety of components. These components are distributed in the environment and interoperate by making use of each other’s services. In the A-MUSE project, we defined a design methodology based on MDA principles that relies on a SOA reference architecture for context-aware mobile applications. This paper shows how abstract concepts in the design of such applications can be applied to realize concrete components that guarantee architectural interoperability. We also present a platform-specific framework that uses BPEL, UDDI registry and web services as target technologies to implement our reference architecture.

    2017-05-01

    The Internet of Things envisions a web-connected infrastructure of billions of sensors and actuation devices. However, the current state-of-the-art presents another reality: monolithic end-to-end applications tightly coupled to a limited set of sensors and actuators. Growing such applications with new devices or behaviors, or extending the existing infrastructure with new applications, involves redesign and redeployment. We instead propose a modular approach to these applications, breaking them into an equivalent set of functional units (context engines) whose input/output transformations are driven by general-purpose machine learning, demonstrating an improvement in compute redundancy and computational complexity with minimal impact on accuracy. In conjunction with formal data specifications, or ontologies, we can replace application-specific implementations with a composition of context engines that use common statistical learning to generate output, thus improving context reuse. We implement interconnected context-aware applications using our approach, extracting user context from sensors in both healthcare and grid applications. We compare our infrastructure to single-stage monolithic implementations with single-point communications between sensor nodes and the cloud servers, demonstrating a reduction in combined system energy by 22-45%, and multiplying the battery lifetime of power-constrained devices by at least 22x, with easy deployment across different architectures and devices.

  8. On designing a pervasive mobile learning platform

    2010-12-01

    Full Text Available This article presents the features, design and architecture of the Myst pervasive game platform that has been applied in creating pervasive mobile learning games in various contexts such as science festivals and museums in Finland. Based on our experiences with the development, we draw a set of design principles for creating successfully a pervasive game platform that can be easily ported to various contexts. These principles advocate openness, flexibility, interaction models, connections to the outside world, and participatory design of the game content. In the evaluation part we present preliminary results of tests conducted in Finland at the SciFest 2008 festival in Joensuu and at the Museum of Technology in Helsinki. The results suggest that games built with the Myst platform are particularly suitable for children and young adults, and these games motivate players to interact with the environment and help to learn by discovering new things. The Myst platform has clearly potential for similar success in other environments due to easy portability and extensibility.

    2007-06-01

    Full Text Available The successful development of mobile learning is dependent on human factors in the use of new mobile and wireless technologies. The majority of mobile learning activity continues to take place on devices that were not designed with educational applications in mind, and usability issues are often reported. The paper reflects on progress in approaches to usability and on recent developments, with particular reference to usability findings reported in studies of mobile learning. The requirements of education are considered as well as the needs of students participating in distance education; discipline-specific perspectives and accessibility issues are also addressed. Usability findings from empirical studies of mobile learning published in the literature are drawn together in the paper, along with an account of issues that emerged in two mobile learning projects based at The Open University, UK, in 2001 and 2005. The main conclusions are: that usability issues are often reported in cases where PDAs have been used; that the future is in scenario-based design which should also take into account the evolution of uses over time and the unpredictability of how devices might be used; and that usability issues should be tracked over a longer period, from initial use through to a state of relative experience with the technology.

    Full Text Available The rise of mobile social media provides unique opportunities for new and creative pedagogies. Pedagogical change requires a catalyst, and we argue that mobile social media can be utilized as such a catalyst. However, the mobile learning literature is dominated by case studies that retrofit traditional pedagogical strategies and pre-existing course activities onto mobile devices and social media. From our experiences of designing and implementing a series of mobile social media projects, the authors have developed a mobile social media framework for creative pedagogies. We illustrate the implementation of our mobile social media framework within the development of a new media minor (an elective set of four courses that explicitly integrates the unique technical and pedagogical affordances of mobile social media, with a focus upon student-generated content and student-determined learning (heutagogy. We argue that our mobile social media framework is potentially transferable to a range of educational contexts, providing a simple design framework for new pedagogies.

    2015-01-01

    Many of our everyday social interactions involve mobile devices. Yet, these tend to only provide good support for distributed social interactions. Although much HCI and CSCW research has explored how we might support collocated, face-to-face situations using mobile devices, much of this work exists as isolated exemplars of technical systems and / or interaction designs. This paper draws on a range of such exemplars to develop a practical design framework intended for guiding the design of new...

    2010-01-01

    Full Text Available This paper gives ten best practices for designing mobile applications that have social-networking functions. The need for such an approach is given by the rapid growth in impor-tance of both social networks and mobile applications. In order to make it easy to follow where the best practices come from, the paper starts with a look at why social networks are more than just a buzz word and at how the field of mobile applications is evolving. It also shows how and why the two fields go together so well. To further make the point, there is a case study of four interesting mobile applications that are textbooks examples of successful applications. The best practices are based on research done for this article and on the extensive knowledge of the author.

    Full Text Available Mobile robot motion control is simplified to a DC motor motion control that may include gear system. The simplest and widespread approach to control the mobile robot motion is the differential drive style, it consists of two in-lines with each a DC motor. Both DC motors are independently powered so the desired movements will rely on how these two DC motors are commanded. Thedevelop design, model and control of Mechatronics mobile robotic system is presented in this paper. The developed robotic system is intended for research purposes as well as for educational process. The model of proposed mobile robot was created and verified using MATLAB-Simulink software.

    Ouiame Filali Marzouki

    2014-05-01

    Full Text Available Inspired by the theory of activity, the context model and previous researches, this paper proposes a model bringing together the key concepts of a mobile learning environment based on the concept of contextualization, major advantage of mobile learning. It details the learning mobile environment, its main components, its characteristics and the different interactions between them. The proposed model meets the constraint of mobile learning complementarity, allowing flexibility in its integration with classroom learning such as e-learning or blended learning. It mainly improves upon conventional learning methods and advocates others such as situated, interactive and connectivist learning. Indeed, research several that mobile learning enhances the educational program and reinstates it into the daily lives of learners through their own mobile technologies. Properly implemented, Mobile Learning can make learning activities as fun, as beneficial and certainly more motivating for learners and educators especially in the mobile era where traditional learning methods don’t meet all learners’ needs. Mobiles, connected and in constant social interaction, learners require learning systems more adapted to their communicative and interactive nature. This paper is an early implementation of this concept in learning systems. It aims to help educators to integrate mobile technologies into their learning activities without alternating their educational goals.

  15. SmartContent—Self-Protected Context-Aware Active Documents for Mobile Environments

    Directory of Open Access Journals (Sweden)

    Francesco Luca De Angelis

    2017-03-01

    Full Text Available Mobile devices make it possible to create, store, access, share or publish personal content on the Internet, anywhere and at anytime. This leads to situations of potential intentional or unintentional misuse of content as well as privacy issues. Recent techniques involving the use of contextual information focus on access of documents stored in clouds, or authentication for secured Web sites. These techniques or more traditional solutions, such as steganography or Digital Rights Management, do not empower the user itself, or data controller in professional settings, with a fine-grained control of the access to or manipulations actions on documents stored on mobile devices, e.g., copying, sharing, etc. In this paper, we propose SmartContent, a novel approach for content protection and privacy. Documents are active and context-aware documents that sense and analyse their current context, e.g., location, noise, neighbouring devices, social network, expiration time, etc. Based on user provided policies, they grant, deny or limit access and manipulation actions, or destroy themselves if necessary. We present the generic model of SmartContent, a concrete architecture and an implementation of a proof-of-concept specifically designed for mobile devices. We deployed it on tablets and showed that a picture dynamically reveals or conceals itself based on sensed context or on changing policies. The implementation leverages the SAPERE middleware specifically developed for context-aware systems.

    Bernhard Klein

    2013-09-01

    Full Text Available Several mobile acceptance models exist today that focus on user interface handling and usage frequency evaluation. Since mobile applications reach much deeper into everyday life, it is however important to better consider user behaviour for the service evaluation. In this paper we introduce the Behaviour Assessment Model (BAM, which is designed to gaining insights about how well services enable, enhance and replace human activities. More specifically, the basic columns of the evaluation framework concentrate on (1 service actuation in relation to the current user context, (2 the balance between service usage effort and benefit, and (3 the degree to which community knowledge can be exploited. The evaluation is guided by a process model that specifies individual steps of data capturing, aggregation, and final assessment. The BAM helps to gain stronger insights regarding characteristic usage hotspots, frequent usage patterns, and leveraging of networking effects showing more realistically the strengths and weaknesses of mobile services

    DeShazo, Jonathan; Harris, Lynne; Turner, Anne; Pratt, Wanda

    2010-01-01

    We have investigated game design and usability for three mobile phone video games designed to deliver diabetes education. The games were refined using focus groups. Six people with diabetes participated in the first focus group and five in the second. Following the focus groups, we incorporated the new findings into the game design, and then conducted a field test to evaluate the games in the context in which they would actually be used. Data were collected remotely about game usage by eight people with diabetes. The testers averaged 45 seconds per question and answered an average of 50 total nutrition questions each. They self-reported playing the game for 10-30 min, which coincided with the measured metrics of the game. Mobile games may represent a promising new way to engage the user and deliver relevant educational content.

  5. Context Aware Handover Algorithms For Mobile Positioning Systems

    Directory of Open Access Journals (Sweden)

    Sazid Z. Khan

    2014-01-01

    Full Text Available Abstract: This work proposes context aware handover algorithms for mobile positioning systems. The algorithms perform handover among positioning systems based on important contextual factors related to position determination with efficient use of battery. The proposed solution which consists of the algorithms is implemented in the form of an Android application named Locate@nav6. The performance of the proposed solution was tested in selected experimental areas. The handover performance was compared with other existing location applications. The proposed solution performed correct handover among positioning systems in 95% of cases studied while two other applications performed correct handover in only 50% of cases studied. Battery usage of the proposed solution is less than one third of the battery usage of two other applications. The analysis of the positioning error of the applications demonstrated that, the proposed solution is able to reduce positioning error indirectly by handing over the task of positioning to an appropriate positioning system. This kept the average error of positioning below 42.1 meters for Locate@nav6 while the average error for two other applications namely Google Latitude and Malaysia maps was between 92.7 and 171.13 meters.

    2013-01-01

    Full Text Available School Information System (SIS is an academic information system developed and implemented for a private school with a purpose to improve the efficiency of information retrieval for students, parents and school authority. One of the initial problems with SIS implementation was that it depended on the availability of computers and internet access. With slow internet connections, authentication process could be time consuming, especially if a website implements various external scripts to improve visual quality. Due to these reasons, as well as the fact that BlackBerry is one of the most popular smartphones in Indonesia, the developers decided to design a simpler but more powerful system that would resolve Blackberry Mobile SIS problems. The mobile SIS was designed, implemented and evaluated to provide a perfect solution for problems related to ease-of-access. The Mobile SIS facilitates students and parents in obtaining academic information anytime, anywhere and without the need for repeated authentication, via BlackBerry mobile connection. Mobile SIS also offers faster loading time relative to traditional website access. Using the push technology service, SIS could now provide students and parents in getting the latest information every time new information gets disseminated.

    1985-01-01

    The relative costs to procure and operate a two-satellite mobile satellite system designed to operate either in the UHF band of the L Band, and with several antenna diameter options in each frequency band was investigated. As configured, the size of the spacecraft is limited to the current RCA Series 4000 Geosynchronous Communications Spacecraft bus, which spans the range from 4000 to 5800 pounds in the transfer orbit. The Series 4000 bus forms the basis around which the Mobile Satellite transponder and associated antennas were appended. Although the resultant configuration has little outward resemblance to the present Series 4000 microwave communications spacecraft, the structure, attitude control, thermal, power, and command and control subsystems of the Series 4000 spacecraft are all adapted to support the Mobile Satellite mission.

    Directory of Open Access Journals (Sweden)

    Kosuke eSato

    2014-10-01

    Full Text Available Does a change in the nature of surrounding social context affect the strength of association between self-esteem and happiness? This paper aims to answer this question from a socio-ecological perspective, focusing on the role of relational mobility. Recent research has shown that this association is stronger in societies that are higher in relational mobility, where there is a greater freedom of choice in interpersonal relationships and group memberships. In this study, we tested if this hypothesis could be applied to situational differences within the same physical setting. Using a quasi-experimental design, we tested if the association between self-esteem and happiness was stronger for first-year students at a Japanese university who had just entered the college and thus were in a relatively higher mobility context, than the second year students at the same university whose relationships tended to be more stable and long-standing. The results showed, as predicted, that the association between self-esteem and happiness was stronger for the first-year students than for the second-year students. Implications for the theory and research on social change are discussed.

    Directory of Open Access Journals (Sweden)

    Sheri A Lippman

    Full Text Available Community mobilizing strategies are essential to health promotion and uptake of HIV prevention. However, there has been little conceptual work conducted to establish the core components of community mobilization, which are needed to guide HIV prevention programming and evaluation.We aimed to identify the key domains of community mobilization (CM essential to change health outcomes or behaviors, and to determine whether these hypothesized CM domains were relevant to a rural South African setting.We studied social movements and community capacity, empowerment and development literatures, assessing common elements needed to operationalize HIV programs at a community level. After synthesizing these elements into six essential CM domains, we explored the salience of these CM domains qualitatively, through analysis of 10 key informant in-depth-interviews and seven focus groups in three villages in Bushbuckridge.CM DOMAINS INCLUDE: 1 shared concerns, 2 critical consciousness, 3 organizational structures/networks, 4 leadership (individual and/or institutional, 5 collective activities/actions, and 6 social cohesion. Qualitative data indicated that the proposed domains tapped into theoretically consistent constructs comprising aspects of CM processes. Some domains, extracted from largely Western theory, required little adaptation for the South African context; others translated less effortlessly. For example, critical consciousness to collectively question and resolve community challenges functioned as expected. However, organizations/networks, while essential, operated differently than originally hypothesized - not through formal organizations, but through diffuse family networks.To date, few community mobilizing efforts in HIV prevention have clearly defined the meaning and domains of CM prior to intervention design. We distilled six CM domains from the literature; all were pertinent to mobilization in rural South Africa. While some adaptation of

    1999-01-01

    Kalman filters have for a long time been widely used on mobile robots as a location estimator. Many different Kalman filter designs have been proposed, using models of various complexity. In this paper, two different design methods are evaluated and compared. Focus is put on the common setup where...... the mobile robot is equipped with a dual encoder system supported by some additional absolute measurements. A common filter type for this setup is the odometric filter, where readings from the odometry system on the robot are used together with the geometry of the robot movement as a model of the robot....... If additional kinematic assumptions are made, for instance regarding the velocity of the robot, an augmented model can be used instead. This kinematic filter has some advantages when used intelligently, and it is shown how this type of filter can be used to suppress noise on encoder readings and velocity...

  1. A Context-Aware Mobile User Behavior-Based Neighbor Finding Approach for Preference Profile Construction

    Directory of Open Access Journals (Sweden)

    Qian Gao

    2016-01-01

    Full Text Available In this paper, a new approach is adopted to update the user preference profile by seeking users with similar interests based on the context obtainable for a mobile network instead of from desktop networks. The trust degree between mobile users is calculated by analyzing their behavior based on the context, and then the approximate neighbors are chosen by combining the similarity of the mobile user preference and the trust degree. The approach first considers the communication behaviors between mobile users, the mobile network services they use as well as the corresponding context information. Then a similarity degree of the preference between users is calculated with the evaluation score of a certain mobile web service provided by a mobile user. Finally, based on the time attenuation function, the users with similar preference are found, through which we can dynamically update the target user’s preference profile. Experiments are then conducted to test the effect of the context on the credibility among mobile users, the effect of time decay factors and trust degree thresholds. Simulation shows that the proposed approach outperforms two other methods in terms of Recall Ratio, Precision Ratio and Mean Absolute Error, because neither of them consider the context mobile information.

Experiments are then conducted to test the effect of the context on the credibility among mobile users, the effect of time decay factors and trust degree thresholds. Simulation shows that the proposed approach outperforms two other methods in terms of Recall Ratio, Precision Ratio and Mean Absolute Error, because neither of them consider the context mobile information.

    The disruptive innovation of smartphone technology has enabled the development of mobile sensing applications leveraged on specialized sensors embedded in the device. These novel mobile phone applications rely on advanced sensor information processes, which mainly involve raw data acquisition, feature extraction, data interpretation and transmission. However, the continuous accessing of sensing resources to acquire sensor data in smartphones is still very expensive in terms of energy, particularly due to the periodic use of power-intensive sensors, such as the Global Positioning System (GPS) receiver. The key underlying idea to design energy-efficient schemes is to control the duty cycle of the GPS receiver. However, adapting the sensing rate based on dynamic context changes through a flexible middleware has received little attention in the literature. In this paper, we propose a novel modular middleware architecture and runtime environment to directly interface with application programming interfaces (APIs) and embedded sensors in order to manage the duty cycle process based on energy and context aspects. The proposed solution has been implemented in the Android software stack. It allows continuous location tracking in a timely manner and in a transparent way to the user. It also enables the deployment of sensing policies to appropriately control the sampling rate based on both energy and perceived context. We validate the proposed solution taking into account a reference location-based service (LBS) architecture. A cloud-based storage service along with online mobility analysis tools have been used to store and access sensed data. Experimental measurements demonstrate the feasibility and efficiency of our middleware, in terms of energy and location resolution.

    Full Text Available Background: Social mobility is defined as the co-occurrence of self-directed locomotion and direct peer interaction. Social mobility is a product of dynamic child-environment interactions and thus likely to vary across contexts (e.g., classroom, gymnasium and playground. Purpose: The purpose of the present study was to examine differences in children’s social mobility (1 across contexts by age, and (2 between non-disabled and disabled children. Method: Participants (n = 55 non-disabled and 3 disabled children; Mage = 3.1 years, SD = 1.4 were video-recorded within a university-based early learning center. Children were recorded for 20 minutes in each context: classroom, gymnasium, and playground. A 15-second momentary time sampling method was used to code social mobility, the simultaneous occurrence of self-directed locomotion and direct peer interaction. This variable was calculated as percent time within each context. Results: A planned Friedman’s rank ANOVA (n = 55, stratified by age, indicated that older children (3-5 years old differed across contexts in their social mobility (χ2 (2 ~ 7.3 – 10.5, p < 0.025, whereas younger children (1-2 years old were similar across contexts. Social mobility was significantly lower in the classroom compared to the playground and gymnasium (with no difference between the latter contexts for older children. Visual analysis confirmed that disabled children (n = 3 engaged in substantially less time in social mobility (average 0% - 1%, compared to non-disabled, age-similar peers (2-3 year olds average 1% -12% across all contexts. Conclusion: A substantial gap exists between non-disabled and disabled children for social mobility. There is an increase in magnitude and variability of social mobility around age 3 that suggests the gap between non-disabled and disabled children will continue to widen.

    Conservation strategies to tackle habitat loss and fragmentation require actions at the local (e.g., improving/expanding existing habitat patches) and landscape level (e.g., creating new habitat in the matrix). However, the relative importance of these actions for biodiversity is still poorly understood, leading to debate on how to prioritize conservation activities. Here, we assess the relative importance of local vs. landscape-level attributes in determining the use of woodlands by bats in fragmented landscapes; we also compare the role of habitat amount in the surrounding landscape per se vs. a combination of both habitat amount and configuration and explore whether the relative importance of these attributes varies with species mobility and landscape context. We conducted acoustic surveys in 102 woodland patches in the UK that form part of the WrEN project (www.wren-project.com), a large-scale natural experiment designed to study the effects of 160 yr of woodland creation on biodiversity and inform landscape-scale conservation. We used multivariate analysis and a model-selection approach to assess the relative importance of local (e.g., vegetation structure) and landscape-level (e.g., amount/configuration of surrounding land types) attributes on bat occurrence and activity levels. Species mobility was an important trait determining the relative importance of local vs. landscape-level attributes for different bat species. Lower mobility species were most strongly influenced by local habitat quality; the landscape became increasingly important for higher mobility species. At the landscape-scale, a combination of habitat amount and configuration appeared more important than habitat amount alone for lower mobility species, while the opposite was observed for higher mobility species. Regardless of species mobility, landscape-level attributes appeared more important for bats in a more homogeneous and intensively farmed landscape. Conservation strategies involving

    Mobile applications are increasingly being deployed in healthcare and nurses are expected to use them during their education, practice and during training of patients. In this paper we describe how an approach to modelling user needs known as the user-task-context matrix has been applied to help guide in developing requirements for new mobile applications as well as for selecting applications to be used in different aspects of nursing and patient education. The approach involves first brainstorming the different classes of users of an application and then specifying possible tasks the application can be used for. In addition, different contexts of use of the application are then specified. Application of the method is described for improving understanding of user needs in both design and procurement of healthcare apps related to nursing education.

    Full Text Available The emergence of new mobile devices, such as smartphones and tablets, are changing how we interact with news. Accessing information from these devices has all the advantages offered by newspapers on the web, also allowing more personalized consumption. Apart from the obvious advantages of using this type of individual handsets,now they sum up the possibility of enjoying technical features such as GPS receiver, accelerometer or video cameras embedded in those devices. These technologies could enrich the news contents and a good example of this potential is the Augmented Reality (AR: the possibility of placing layers of virtual information on real images captured at the moment is an opportunity to enrich the news with a contextualization that can be continuously updated. This paper seeks to explain the role of AR on mobile journalism.

  4. GPU-based Parallel Application Design for Emerging Mobile Devices

    Gupta, Kshitij

    A revolution is underway in the computing world that is causing a fundamental paradigm shift in device capabilities and form-factor, with a move from well-established legacy desktop/laptop computers to mobile devices in varying sizes and shapes. Amongst all the tasks these devices must support, graphics has emerged as the 'killer app' for providing a fluid user interface and high-fidelity game rendering, effectively making the graphics processor (GPU) one of the key components in (present and future) mobile systems. By utilizing the GPU as a general-purpose parallel processor, this dissertation explores the GPU computing design space from an applications standpoint, in the mobile context, by focusing on key challenges presented by these devices---limited compute, memory bandwidth, and stringent power consumption requirements---while improving the overall application efficiency of the increasingly important speech recognition workload for mobile user interaction. We broadly partition trends in GPU computing into four major categories. We analyze hardware and programming model limitations in current-generation GPUs and detail an alternate programming style called Persistent Threads, identify four use case patterns, and propose minimal modifications that would be required for extending native support. We show how by manually extracting data locality and altering the speech recognition pipeline, we are able to achieve significant savings in memory bandwidth while simultaneously reducing the compute burden on GPU-like parallel processors. As we foresee GPU computing to evolve from its current 'co-processor' model into an independent 'applications processor' that is capable of executing complex work independently, we create an alternate application framework that enables the GPU to handle all control-flow dependencies autonomously at run-time while minimizing host involvement to just issuing commands, that facilitates an efficient application implementation. Finally, as

    This paper presents an initial overview of insights gained into how older adults mobilize in the home and community, based on data from inertial sensors which were worn by study participants over a 7-day period. The addition of a wearable camera provided additional contextual information which can be used to assess mobility and understand the factors that influence it in the free living environment. Seven days of data collected from a group of older adults who had experienced one or more falls in the previous six months was compared to that of a control group with no history of falling. Results showed that both groups spent relatively little time walking in challenging environmental conditions, and that the fallers spent significantly less time walking under regular conditions (no effect on gait) and outdoors. Analysis of gait metrics showed that the fallers were slightly slower in general, and more noticeable differences were observed when the participants were regrouped according to mobility levels determined from baseline assessments using traditional methods.

    2015-01-01

    Full Text Available Sensor-equipped mobile devices have allowed users to participate in various social networking services. We focus on proximity-based mobile social networking environments where users can share information obtained from different places via their mobile devices when they are in proximity. Since people are more likely to share information if they can benefit from the sharing or if they think the information is of interest to others, there might exist community structures where users who share information more often are grouped together. Communities in proximity-based mobile networks represent social groups where connections are built when people are in proximity. We consider information influence (i.e., specify who shares information with whom as the connection and the space and time related to the shared information as the contexts. To model the potential information influences, we construct an influence graph by integrating the space and time contexts into the proximity-based contacts of mobile users. Further, we propose a two-phase strategy to detect and track context-aware communities based on the influence graph and show how the context-aware community structure improves the performance of two types of mobile social applications.

  15. Addressing Cultural Contexts in the Management of Stress via Narrative and Mobile Technology.

    Science.gov (United States)

    Lee, Matthew D; Kang, Xiao; Hanrahan, Nancy

    2014-01-01

    In developing applications for stress management and mental health, developers have largely ignored cultural context in design, opting instead to produce apps for a general audience. However, apps designed without a specific population in mind actually have limited reach. Generally stress trackers and socalled "therapists in your pocket", tend to be lost among a jungle of other generic apps that appeal only to the quantified self population and those already predisposed to help-seeking behavior. To reach a broader audience, designing for a specific population may have appeal. The AppHappy Project's Journey to the West is a mobile app being developed by a multidisciplinary group of students at the University of Pennsylvania. The objective is to promote better stress management and mental health among Asian international college students and facilitate their social integration with the general student population. With a prevalence of depression twice that of domestic college students, a reluctance to engage in help-seeking behavior due to stigma, and the challenge of cultural integration, creating interventions for this population requires a different approach to app-mediated therapy. Journey to the West packages bite-sized pieces of Cognitive Behavioral Therapy techniques within the framework of a role-playing game. Every element of its design-from its characters to its art style, from its narrative to its mechanics to its approach to community features-is rooted in a culturally appropriate context. An avatar serves as a surrogate of self while experiencing externalized stressors. Each quest blends therapeutic elements into gameplay with the goal of building resilience towards stressful events.

  19. An ARM Mobile Facility Designed for Marine Deployments

    Wiscombe, W. J.

    2007-05-01

    The U.S. Dept. of Energy's ARM (Atmospheric Radiation Measurements) Program is designing a Mobile Facility exclusively for marine deployments. This marine facility is patterned after ARM's land Mobile Facility, which had its inaugural deployment at Point Reyes, California, in 2005, followed by deployments to Niger in 2006 and Germany in 2007 (ongoing), and a planned deployment to China in 2008. These facilities are primarily intended for the study of clouds, radiation, aerosols, and surface processes with a goal to include these processes accurately in climate models. They are preferably embedded within larger field campaigns which provide context. They carry extensive instrumentation (in several large containers) including: cloud radar, lidar, microwave radiometers, infrared spectrometers, broadband and narrowband radiometers, sonde-launching facilities, extensive surface aerosol measurements, sky imagers, and surface latent and sensible heat flux devices. ARM's Mobile Facilities are designed for 6-10 month deployments in order to capture climatically-relevant datasets. They are available to any scientist, U.S. or international, who wishes to submit a proposal during the annual Spring call. The marine facility will be adapted to, and ruggedized for, the harsh marine environment and will add a scanning two-frequency radar, a boundary-layer wind profiler, a shortwave spectrometer, and aerosol instrumentation adapted to typical marine aerosols like sea salt. Plans also include the use of roving small UAVs, automated small boats, and undersea autonomous vehicles in order to address the point-to-area-average problem which is so crucial for informing climate models. Initial deployments are planned for small islands in climatically- interesting cloud regimes, followed by deployments on oceanic platforms (like decommissioned oil rigs and the quasi-permanent platform of this session's title) and eventually on large ships like car carriers plying routine routes.

  20. Relay Ability Estimation and Topology Control Using Multidimensional Context Parameters for Mobile P2P Multicast

    Directory of Open Access Journals (Sweden)

    Kubo Hiroyuki

    2011-01-01

    Full Text Available We focus on mobile P2P multicast, in which mobile end nodes not only act as receivers but also relay the received stream forward to others. In mobile P2P multicast, negative effects caused by the change of available bandwidth and the disconnection of mobile nodes are propagated to the downstream nodes. To solve this problem, we developed a novel node-allocation framework using the multidimensional context parameters of each mobile node, which include available bandwidth, disconnection rate, and the remaining battery capacity. Considering the significance of each parameter, our method integrates these parameters into a single parameter called relay ability. Taking the relay ability into account, each node is allocated to the multicast topology to minimize the negative effects mentioned above. To test our method, we applied our framework to conventional P2P multicast topology and show the results from comparative evaluations through computer simulation.

    Full Text Available Over the last decade, several research initiatives have investigated the potentials of the educational paradigm shift from the traditional one-size-fits-all teaching approaches to adaptive and personalized learning. On the other hand, mobile devices are recognized as an emerging technology to facilitate teaching and learning strategies that exploit individual learners’ context. This has led to an increased interest on context-aware adaptive and personalized mobile learning systems aiming to provide learning experiences delivered via mobile devices and tailored to learner’s personal characteristics and situation. To this end, in this paper we present a context-aware adaptive and personalized mobile learning system, namely the Units of Learning mobile Player (UoLmP, which aims to support semi-automatic adaptation of learning activities, that is: (a adaptations to the interconnection of the learning activities (namely, the learning flow and (b adaptations to the educational resources, tools and services that support the learning activities. Initial evaluation results from the use of UoLmP provide evidence that UoLmP can successfully adapt the learning flow of an educational scenario and the delivery of educational resources, tools and services that support the learning activities. Finally, these adaptations can facilitate students to complete successfully the learning activities of an educational scenario.

    2009-01-01

    Context as the dynamic information describing the situation of items and users and affecting the users decision process is essential to be used by recommender systems in mobile commerce to guarantee the quality of recommendation. This paper proposes a novel multidimensional approach for context aware recommendation in mobile commerce. The approach represents users, items, context information and the relationship between them in a multidimensional space. It then determines the usage patterns of each user under different contextual situations and creates a new 2 dimensional recommendation space and does the final recommendation in that space. This paper also represents an evaluation process by implementing the proposed approach in a restaurant food recommendation system considering day, time, weather and companion as the contextual information and comparing the approach with the traditional 2 dimensional one. The results of comparison illustrates that the multidimensional approach increases the recommendation q...

  13. Cluster-Based Context-Aware Routing Protocol for Mobile Environments

    Directory of Open Access Journals (Sweden)

    Ahmed. A. A. Gad-ElRab

    2015-01-01

    Full Text Available Mobile environment has many issues due to mobility, energy limitations and status changing over time. Routing method is an important issue and has a significant impact in mobile networks, whereas selecting the optimum routing path will reduce the wasting in network resources, reduce network overhead and increase network reliability and lifetime. To decide which path will achieve the networks objectives, we need to construct a new routing algorithm that uses context attributes of a mobile device such as available bandwidth, residual energy, connection number and mobility value. In this paper, we propose a new mobile nodes ranking scheme based on the combination of two multi-criteria decision making approaches, the analytic hierarchy process (AHP and the technique for order performance by similarity to ideal solution (TOPSIS in Fuzzy environments. The Fuzzy AHP is used to analyze the structure of the clusterhead selection problem and to determine weights of the criteria, while the Fuzzy TOPSIS method is used to obtain the final mobile node ranking value. By basing on node ranking, we propose a new cluster based routing algorithm select the optimal clusterheads and the best routing path. Our simulation results show that the proposed method increases the network accuracy and lifetime and reduces network overhead.

    Mobile populations, including truck drivers, are at elevated risk of acquiring HIV and other sexually transmitted infections (STI). However, measures of mobility have been poorly operationalized and little research exists exploring the psychosocial context of mobility and sexual risk taking. A systematic sample of 1775 male truck drivers underwent interview at two customs stations on the Southern Brazilian international border in 2003. The psychosocial effect of being mobile was assessed by clustering truckers based on perceptions of the liminal environment, or being outside of one's normal social environment. The relationship between physical mobility (nights spent at home) and liminal cluster with sexual partnerships was assessed. The clustering procedure yielded three dispositions towards the liminal environment. Compared to truckers in the baseline cluster, those who perceive the environment as (1) very, or (2) moderately permissive had increased odds of reporting a commercial sex partner in the past six months and reported increased numbers of commercial partners. For each week slept at home, the odds of reporting a commercial partner decreased by a factor of 0.73 and the average number of commercial partners decreased by a rate of 0.76. Physical and psychosocial measures of mobility were associated independently with increased partnering on the road. Additional exploration of how the liminal environment shapes mobile populations' sexual decision making and vulnerability to STI is warranted.

    Retha de la Harpe

    2014-10-01

    Full Text Available The context of this study is home-based healthcare in a South African resource-restricted community. The research case involved the design and development of a mobile care data application, created to assist community caregivers in their professional activities. The development principles of a suitable application for feature phones (limited functionality in this context are not fully established, however. For the mobile care data application, a participatory design approach was employed. It was observed, conversely, that the level of participation of all stakeholders differed significantly. It was especially observed that the designer and end-users were less involved in the actual development of the prototype. These differences may have an influence on the end product/result. Actor-network theory may provide the mechanism to describe how the human and non-human actors formed relations as they participate in these processes. Considering the alignment of such networks, the coordination, devices and passages during the four translation moments provide valuable insights in the design and development of technology products. This paper will consider these elements in more depth. With a social embeddedness perspective the level of participation was high during the design of the proposed ICT solution with the active participation of the care givers from the developing context. The socio-economic factors of the developing context influenced the development of the mobile application with the complexities of the socio-technical context evident in the difficult translations between the participants

    Full Text Available This study presents the processes undertaken in the design and development of an intelligent omni-directional mobile robot using four custom-made mecanum wheels. The mecanum wheel developed consists of nine rollers made from delrin. All mecanum wheels are independently powered using four units of precisian gear DC motors and the wheel/motor assemblies were mounted directly to the robot chassis made using an aluminum frame. A four channel high power H-bridge using 2 units of LMD 18200 motor drivers IC circuit was design, built and interfaced to a BasicStamp (BS2 microcontroller board. Basic mobility algorithm using BasicStamp software was developed to test the basic mobility capabilities and test the qualitative view of the system's mobility performance. An experiment was set-up to analyze the motion characteristic of the mobile robot motion in Y-axis, X-axis and rotary motion. Data from the experiment will be used for mathematically model for mobile robot platform and speed controller modeling and design. Mecanum wheel mobile robot provides a convenient platform for further development in the mobile platform. The combination of mechanical design on the wheel and chassis, motion control and multiple input/output sensors allow the exploration of large number of control algorithm and software to be implemented to the robot for practical applications.

  1. Energy Conservation in Mobile Devices and Applications: A Case for Context Parsing, Processing and Distribution in Clouds

    Directory of Open Access Journals (Sweden)

    Saad Liaquat Kiani

    2013-01-01

    Full Text Available Context information consumed and produced by the applications on mobile devices needs to be represented, disseminated, processed and consumed by numerous components in a context-aware system. Significant amounts of context consumption, production and processing takes place on mobile devices and there is limited or no support for collaborative modelling, persistence and processing between device-Cloud ecosystems. In this paper we propose an environment for context processing in a Cloud-based distributed infrastructure that offloads complex context processing from the applications on mobile devices. An experimental analysis of complexity based context-processing categories has been carried out to establish the processing-load boundary. The results demonstrate that the proposed collaborative infrastructure provides significant performance and energy conservation benefits for mobile devices and applications.

    YU Jin-xia; CAI Zi-xing; DUAN Zhuo-hua; ZOU Xiao-bing

    2006-01-01

    A dead reckoning system for a wheeled mobile robot was designed, and the method for robot's pose estimation in the 3D environments was presented on the basis of its rigid-body kinematic equations. After analyzing the locomotion architecture of mobile robot and the principle of proprioceptive sensors, the kinematics model of mobile robot was built to realize the relative localization. Considering that the research on dead reckoning of mobile robot was confined to the 2 dimensional planes, the locomotion of mobile robot in the 3 coordinate axis direction was thought over in order to estimate its pose on uneven terrain. Because the computing method in a plane is rather mature, the calculation in height direction is emphatically represented as a key issue. With experimental results obtained by simulation program and robot platform, the position of mobile robot can be reliably estimated and the localization precision can be effectively improved, so the effectiveness of this dead reckoning system is demonstrated.

    2011-04-01

    Full Text Available Against the conceptual and theoretical background of a socio-culturally orientated approach to mobile learning (Pachler, Bachmair and Cook, 2010, this paper examines the evaluation of user-generated contexts by referring to an example from the use of mobile phones in schools. We discuss how mobile device-related, user- generated contexts around structures, agency and cultural practices might be brought into a fruitful relationship with institution-based learning. And, we provide categories for evaluating the use of mobile devices to generate meaning from and with fragmented and discontinuous media and modes at the interface of learning in formal, institutionalised and informal, self-directed settings. The evaluation criteria build on the framework of a socio-cultural ecology of mobile learning developed by the London Mobile Learning Group.

    Full Text Available Opportunities and needs are increasing to input Japanese sentences on mobile phones since performance of mobile phones is improving. Applications like E-mail, Web search, and so on are widely used on mobile phones now. We need to input Japanese sentences using only 12 keys on mobile phones. We have proposed a method to input Japanese sentences on mobile phones quickly and easily. We call this method number-Kanji translation method. The number string inputted by a user is translated into Kanji-Kana mixed sentence in our proposed method. Number string to Kana string is a one-to-many mapping. Therefore, it is difficult to translate a number string into the correct sentence intended by the user. The proposed context-aware mapping method is able to disambiguate a number string by artificial neural network (ANN. The system is able to translate number segments into the intended words because the system becomes aware of the correspondence of number segments with Japanese words through learning by ANN. The system does not need a dictionary. We also show the effectiveness of our proposed method for practical use by the result of the evaluation experiment in Twitter data.

    2016-01-01

    Full Text Available Security management in wireless networks has to deal with the changing character of the environment, which can further lead to decision making problem for unexpected events. Among a huge list of devices, the mobile ones are especially vulnerable to this situation. The solution for adapting systems and applications to dynamic environments can be context-aware description of the user actions, which gives a possibility to take into account the factors that influence these actions. In the article, we propose a context-aware security adjusting model, which is based on proposition logic and incorporates mechanisms that assist in the reasoning process. The main benefits that differentiate our approach from similar ones are a formal representation of the model, the usage of the whole spectrum of context attributes, the detection and analysis of contextual data integrity, and conflicting rules’ eradication capability. All these traits transcribe into a more effective way of adjusting security measures in accordance with existing circumstances. To illustrate the proposed approach, we present the case study of context-aware security management for mobile devices.

  17. Adaptive Power Saving Method for Mobile Walking Guidance Device Using Motion Context

    Directory of Open Access Journals (Sweden)

    Jin-Hee Lee

    2015-01-01

    Full Text Available It is important to recognize the motion of the user and the surrounding environment with multiple sensors. We developed a guidance system based on mobile device for visually impaired person that helps the user to walk safely to the destination in the previous study. However, a mobile device having multiple sensors spends more power when the sensors are activated simultaneously and continuously. We propose a method for reducing the power consumption of a mobile device by considering the motion context of the user. We analyze and classify the user’s motion accurately by means of a decision tree and HMM (Hidden Markov Model that exploit the data from a triaxial accelerometer sensor and a tilt sensor. We can reduce battery power consumption by controlling the number of active ultrasonic sensors and the frame rate of the camera used to acquire spatial context around the user. This helps us to extend the operating time of the device and reduce the weight of the device’s built-in battery.

    2008-12-01

    Full Text Available Although mobile learning is a popular topic in current research, it is not well conceptualized. Many researchers rely on under-theorized conceptions of the topic, and those who have tried to refine the ideas involved have found this to be complex and difficult. In this paper a new interpretation of the concept ‘mobile learning' is offered, drawing on the tradition of activity theory. The interpretation focuses on the continuity of learning activities that take place in multiple contexts, which are embodied as the combination of the physical and social setting of the learning activities. The paper starts by sketching the current research context and then outlines the theoretical tradition within which the interpretation of ‘mobile learning' is located. Then the new interpretation is offered and the concepts are applied to case studies to illustrate how this new understanding develops current thinking in the area. The paper concludes by discussing the implications for research of adopting such a perspective.

The low-level programming and compatibility problems of the J2ME, along with UI designing difficulties, makes it hard for most people -even programmers- to broadcast their content to the widespread mobile phones used by nearly all people. This system provides user-friendly, PC-based tools for creating a tree index of pages and inserting multiple multimedia contents (e.g. sound, video and picture) in each page for creating a J2ME mobile application. The output is a stand-alone Java mobile application that has a user interface, shows texts and pictures and plays music and videos regardless of the type of devices used as long as the devices support the J2ME platform. Bitmap fonts have also been used thus Middle Eastern languages can be easily...

    The concept of Intelligent Mechanical Design (IMD) is presented to show how a mechanical structure can be designed to affect robot controllability, simplification and task performance. Exploring this concept produces landmarks in the territory of mechanical robot design in the form of seven design principles. The design principles, which we call the Mecha-Telligence Principles (MTP), provide guidance on how to design mechanics for autonomous mobile robots. These principles guide us to ask the right questions when investigating issues concerning self-controllable, reliable, feasible, and compatible mechanics for autonomous mobile robots. To show how MTP can be applied in the design process we propose a novel methodology, named as Mecha-Telligence Methodology (MTM). Mechanical design by the proposed methodology is based on preference classification of the robot specification described by interaction of the robot with its environment and the physical parameters of the robot mechatronics. After defining new terms, we investigate the feasibility of the proposed methodology to the mechanical design of an autonomous mobile sewer inspection robot. In this industrial project we show how a passive-active intelligent moving mechanism can be designed using the MTM and employed in the field.

    2014-12-01

    Full Text Available This paper aims to identify multimodal designs for learning in diverse and developing contexts, where access to resources remains vastly unequal. Using case studies from South African education, the paper explores ways of surfacing the range of students’ resources which are often not noticed or valued in formal educational settings. The studies showcased here demonstrate how ethnographic and textually-based approaches can be combined. Opening up the semiotic space of the classroom through multimodal designs for learning is important for finding innovative ways of addressing access, diversity, and past inequalities. This is of relevance not only to South Africa, but a range of global contexts. The paper argues that multimodal designs for learning can involve interrogating the relation between ‘tradition’ and ‘modernity’; harnessing students’ creative practices as resources for pedagogy; developing metalanguages for critical reflection; creating less regulated pedagogical spaces in order to enable useful teaching and learning practices.

  15. Visual Pollution in the Context of Conflicting Design Requirements

    Directory of Open Access Journals (Sweden)

    2009-07-01

    Full Text Available All designs (graphic, product, and interior designs are directed to consider certain requirements which are followed by logical thinking to fulfill a design process. Once the requirements of each design have been well-considered and the logical design process has been fulfilled, the design is complete. Ideally, all designs are not supposed to be in conflict with each other because each one is based on a logical design process. In reality, however, the mutual existence of these designs has produced conflicting requirements and thereby conflicting logics. This conflict can be seen in visual pollution. This paper will examine the impact of visual pollution caused by billboards, street signs, posters, houses/buildings, automobiles, shopfront graphic designs, packaging designs, graffiti, etc. in the context of conflicting logics/requirements. Today, opposition grows everywhere against all visually polluting designs and outdoor advertising is the most prominent one. Some people think that it should be banned from the city. Some others, however, think that if advertisements are removed from the city, it will become a bland concrete jungle. Every city in Indonesia needs a clean-city law to control illegal advertisements and signs. It is possible to make legal yet attractive advertisements that will give positive contribution to “visual democracy” in Indonesia.

    Full Text Available Currently, many researches in Mobile government secure transmission of plaintext with universal availability in all GSM networks had been proposed. The most important characteristic of this research is a new system that contains all the capabilities and plugging security holes in the algorithms and methods used in previous systems design. The main reason of the intensification of efforts for the purpose of security in a mobile government is the real threat that accompanies the movement of transaction from the sender to the recipient. Moreover, mobile government used in improving convenience is one the clearest manifestations of the development of society and solving various problems using other method related to availability, speed, financial, in addition to the administrative issues related to the fight against corruption side a side with Egovernment. In this paper, illustrating how a mobile phone can provide citizens and Non-government organizations with mobile government services relevant to the design and implementation of security mechanisms coinciding with the birth of the third generation technology in Iraq so as to ensure the highest level of security transaction provided by UMTS security is also built upon GSM network.

    Mobility support on the network layer is of special importance, as the network layer holds together the huge Internet with common protocol IP. Although based on possibility different wireless or wired technologies, all nodes of the network should be able to communicate. Therefore, mobile IP (an extension of the classical IP) has been designed which enables mobility in the Internet without changing existing wired systems. However, mobile IP leaves some points unsolved. Especially, if it comes to security, efficient of the packet flow that is called triangular routing. Especially triangular routing can cause unnecessary overhead for the network. Furthermore latency can increase dramatically. This is particularly unfortunate if two communicating hosts are separated by transatlantic links. In order to this problem, many methods like IPv6 and ROMIP are proposed. But these methods have limitation. In other words, they have not compatibility because of needing modification or original IP scheme. Especially ROMIP is very complex and the overhead of control message and processing are serious. The problem of inconsistency of Binding caches may occur tool. We therefore propose and analyze the DRMIP (Direct Routing Mobile IP) which do not modify IP source needed in the sender, is compatible with IP and Mobile IP.

    Mobile health has been a new trend all over the world with the rapid development of intelligent terminals and mobile internet. It can help patients monitor health in-house and is convenient for doctors to diagnose remotely. Smart-phone-based mobile health has big advantages in cost and data sharing. Front end design of it mainly focuses on two points: one is implementation of medical sensors aimed at measuring kinds of medical signal; another is acquisition of medical signal from sensors to smart phone. In this paper, the above two aspects were both discussed. First, medical sensor implementation was proposed to refer to mature measurement solutions with ECG (electrocardiograph) sensor design taken for example. And integrated chip using can simplify design. Then second, typical data acquisition architecture of smart phones, namely Bluetooth and MIC (microphone)-based architecture, were compared. Bluetooth architecture should be equipped with an acquisition card; MIC design uses sound card of smart phone instead. Smartphone-based virtual instrument app design corresponding to above acquisition architecture was discussed. In experiments, Bluetooth and MIC architecture were used to acquire blood pressure and ECG data respectively. The results showed that Bluetooth design can guarantee high accuracy during the acquisition and transmission process, and MIC design is competitive because of low cost and convenience.

  20. Context sensitivity and ambiguity in component-based systems design

    Energy Technology Data Exchange (ETDEWEB)

    Bespalko, S.J.; Sindt, A.

    1997-10-01

    Designers of components-based, real-time systems need to guarantee to correctness of soft-ware and its output. Complexity of a system, and thus the propensity for error, is best characterized by the number of states a component can encounter. In many cases, large numbers of states arise where the processing is highly dependent on context. In these cases, states are often missed, leading to errors. The following are proposals for compactly specifying system states which allow the factoring of complex components into a control module and a semantic processing module. Further, the need for methods that allow for the explicit representation of ambiguity and uncertainty in the design of components is discussed. Presented herein are examples of real-world problems which are highly context-sensitive or are inherently ambiguous.

    2010-07-01

    Full Text Available ‘Desktop’ social networking services are migrating to mobile devices. Research into the design of mobile social software (MoSoSo, especially its communication design, is emerging. The case we present is from a collaborative, interdisciplinary research project into communicative design innovation concerning these technologies. In focus is the design of what we label the communicative prototype for an interaction and media centred view of social software development. This view is applied to an exploratory design research case that extends an established online social service to the iPhone/iPod platform. The conceptual design in the case is intended to enable the discovery of independent, non-commercial music. The projected service was developed in consultation with a national public service broadcaster. We frame the design and analysis within a sociocultural approach to mediated communication and research by design. We employ mixed methods both in design and in research. We argue that a communicative stance in early concept development offers valuable insights on the ongoing design of social software. The communication expertise of interaction designers is central to this.

    2012-04-01

    Full Text Available This paper examines the factors influencing the continuance decisions of the early adopters of m-banking services in Kerala, India. The study was designed in the backdrop of the issues faced by the banks to attract more customers irrespective of the huge mobile penetration in the country. The study used constructs adopted from Technology Acceptance Model along with constructs of perceived service quality, perceived credibility and perceived risk to empirically establish the influence on satisfaction and continuance usage intentions. The study could find strong linkage between perceived service quality, satisfaction and continuance intentions. The study also confirmed that after adoption of the technology, the customer finds satisfaction in the quality parameters of the service. Perceptions about the risks involved in m-banking had adverse impact on service quality and satisfaction. Continuance intentions were found solely dependent on satisfaction in the m-banking context in Kerala.

    2004-09-01

    Hospitals are convenient settings for deployment of ubiquitous computing technology. Not only are they technology-rich environments, but their workers experience a high level of mobility resulting in information infrastructures with artifacts distributed throughout the premises. Hospital information systems (HISs) that provide access to electronic patient records are a step in the direction of providing accurate and timely information to hospital staff in support of adequate decision-making. This has motivated the introduction of mobile computing technology in hospitals based on designs which respond to their particular conditions and demands. Among those conditions is the fact that worker mobility does not exclude the need for having shared information artifacts particular locations. In this paper, we extend a handheld-based mobile HIS with ubiquitous computing technology and describe how public displays are integrated with handheld and the services offered by these devices. Public displays become aware of the presence of physicians and nurses in their vicinity and adapt to provide users with personalized, relevant information. An agent-based architecture allows the integration of proactive components that offer information relevant to the case at hand, either from medical guidelines or previous similar cases.

    Lu, Zhiyuan; Chen, Xiang; Dong, Zhongfei; Zhao, Zhangyan; Zhang, Xu

    2016-09-01

    This paper introduces a pulse oximeter prototype designed for mobile healthcare. In this prototype, a reflection pulse oximeter is embedded into the back cover of a smart handheld device to offer the convenient measurement of both heart rate (HR) and SpO2 (estimation of arterial oxygen saturation) for home or mobile applications. Novel and miniaturized circuit modules including a chopper network and a filtering amplifier were designed to overcome the influence of ambient light and interferences that are caused by embedding the sensor into a flat cover. A method based on adaptive trough detection for improved HR and SpO2 estimation is proposed with appropriate simplification for its implementation on mobile devices. A fast and effective photoplethysmogram validation scheme is also proposed. Clinical experiments have been carried out to calibrate and test our oximeter. Our prototype oximeter can achieve comparable performance to a clinical oximeter with no significant difference revealed by paired t -tests ( p = 0.182 for SpO2 measurement and p = 0.496 for HR measurement). The design of this pulse oximeter will facilitate fast and convenient measurement of SpO2 for mobile healthcare.

    2012-10-01

    Full Text Available The paper discusses the theoretical concepts, design considerations and preliminary findings from Smart Mobility, a research project currently being undertaken with the City of St. Gallen. The project aims at designing measures to encourage the increased use of public and non-motorised transport by integrating behavioural economic principles into public policy. The extensive involvement of citizens and their participation in the design of the measures are to support their democratic legitimization and later acceptance. The paper describes the energy policies behind the project and outlines the theoretical framework for integrating behavioural insights into public policy. The strategies envisaged include participatory instruments and methods, especially the use of existing social media channels, capitalizing on social processes and norms to increase the motivation of individuals to use public transport, creating an open innovation space by means of crowdsourcing as well as the proper framing of political communication to achieve changes in mobility patterns.

  13. Wireless Sensor/Actuator Network Design for Mobile Control Applications

    Xia, Feng; Li, Yanjun; Sun, Youxian

    2008-01-01

    Wireless sensor/actuator networks (WSANs) are emerging as a new generation of sensor networks. Serving as the backbone of control applications, WSANs will enable an unprecedented degree of distributed and mobile control. However, the unreliability of wireless communications and the real-time requirements of control applications raise great challenges for WSAN design. With emphasis on the reliability issue, this paper presents an application-level design methodology for WSANs in mobile control applications. The solution is generic in that it is independent of the underlying platforms, environment, control system models, and controller design. To capture the link quality characteristics in terms of packet loss rate, experiments are conducted on a real WSAN system. From the experimental observations, a simple yet efficient method is proposed to deal with unpredictable packet loss on actuator nodes. Trace-based simulations give promising results, which demonstrate the effectiveness of the proposed approach.

    Full Text Available Mobile learning (m-learning is a research field that aims to analyze how mobile devices can contribute to learning. The development of software for mobile devices to support learning is essential for an effective implementation of m-learning or mobile learning environments (MLE. Requirements Engineering processes need to include activities that provoke creativity in the stakeholders to conceive MLEs that actually modify and improve the teaching and learning process. In this context, this paper presents a process for requirements elicitation and documentation of mobile learning environments. This process is based on the concepts of the Design Thinking process that provides a methodology to elicit customer needs, producing simple prototypes that eventually converge to innovative solutions. An experiment was conducted to evaluate if the proposed process contributes to create MLEs that present distinctive and interesting characteristics when compared to existing solutions for a specific problem.

  18. Blackboard Rules for Coordinating Context-aware Applications in Mobile Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    Jean-Marie Jacquet

    2012-08-01

    Full Text Available Thanks to improvements in wireless communication technologies and increasing computing power in hand-held devices, mobile ad hoc networks are becoming an ever-more present reality. Coordination languages are expected to become important means in supporting this type of interaction. To this extent we argue the interest of the Bach coordination language as a middleware that can handle and react to context changes as well as cope with unpredictable physical interruptions that occur in opportunistic network connections. More concretely, our proposal is based on blackboard rules that model declaratively the actions to be taken once the blackboard content reaches a predefined state, but also that manage the engagement and disengagement of hosts and transient sharing of blackboards. The idea of reactiveness has already been introduced in previous work, but as will be appreciated by the reader, this article presents a new perspective, more focused on a declarative setting.

  19. Towards Analytical Modeling for Persuasive Design Choices in Mobile Apps

    Directory of Open Access Journals (Sweden)

    Hamid Mukhtar

    2016-11-01

    Full Text Available Persuasive technology has emerged as a new field of research in the past decade with its applications in various domains including web-designing, human-computer interaction, healthcare systems, and social networks. Although persuasive technology has its roots in psychology and cognitive sciences, researchers from the computing disciplines are also increasingly interested in it. Unfortunately, the existing theories, models, and frameworks for persuasive system design fall short due to absence of systematic design processes mostly used in the computing domains as well as lack of support for appropriate post-analysis. This work provides some insight into such limitations and identifies the importance of analytical modeling for persuasion in mobile applications design. The authors illustrate, using a case study, that appropriate mathematical models can be applied together with user modeling to develop a persuasive system that will allow the designer to consider several design choices simultaneously.

    The design of the mobility enhancement robotic wheelchair (MEBot) was based on input from electric powered wheelchair (EPW) users regarding the conditions they encounter when driving in both indoor and outdoor environments that may affect their safety and result in them becoming immobilized, tipping over, or falling out of their wheelchair. Phase I involved conducting a participatory design study to understand the conditions and barriers EPW users found to be difficult to drive in/over. Phase II consisted of creating a computer-aided design (CAD) prototype EPW to provide indoor and outdoor mobility that addressed these conditions with advanced applications. Phase III involved demonstrating the advanced applications and gathering feedback from end users about the likelihood they would use the advanced applications. The CAD prototype incorporated advanced applications, including self-leveling, curb climbing, and traction control, that addressed the challenging conditions and barriers discussed with EPW users (n = 31) during the participatory design study. Feedback of the CAD design and applications in phase III from end users (n = 12) showed a majority would use self-leveling (83%), traction control (83%), and curb climbing (75%). The overall design of MEBot received positive feedback from EPW users. However, these opinions will need to be reevaluated through user trials as the design advances.

    Full Text Available This paper presents the development of the “intelligent Robotic Wheelchair” (iRW, emphasizing its mobility assistance design. The vehicle uses four Mecanum wheels to facilitate movement in all directions, including sideways, and zero radius of rotation. The iRW requires much less space than ordinary electric wheelchairs in turning and sideways manoeuvres. Based on this moving vehicle, mobility assistance functions are designed for three different operators: the wheelchair user, caregivers, and the iRW itself in autonomous behaviours. Five operation modes, all mutually exclusive, are developed: obstacle avoidance, joystick mode, handlebar mode, teleoperation, and indoor navigation. Man‐machine collaborative control is reflected in the assignment of priorities to the three operators. The functional test performed in this research compared the operational efficiency of the five operation modes.

    Finding measures to enhance the dissemination and implementation of their recommendations has become part of most health technology assessment (HTA) bodies' preoccupations. The Quebec government HTA organization in Canada observed that some of its projects relied on innovative practices in knowledge production and dissemination. A research was commissioned in order to identify what characterized these practices and to establish whether they could be systematized. An exploratory case study was conducted during summer and fall 2010 in the HTA agency in order to determine what made the specificity of its context, and to conceptualize an approach to knowledge production and dissemination that was adapted to the mandate and nature of this form of HTA organization. Six projects were selected. For each, the HTA report and complementary documents were analyzed, and semi-structured interviews were carried out. A narrative literature review of the most recent literature reviews of the principal knowledge into practice frameworks (2005-2010) and of articles describing such frameworks (2000-2010) was undertaken. Our observations highlighted an inherent difficulty as regards applying the dominant knowledge translation models to HTA and clinical guidance practices. For the latter, the whole process starts with an evaluation question asked in a problematic situation for which an actionable answer is expected. The objective is to produce the evidence necessary to respond to the decision-maker's request. The practices we have analyzed revealed an approach to knowledge production and dissemination, which was multidimensional, organic, multidirectional, dynamic, and dependent on interactions with stakeholders. Thus, HTA could be considered as a knowledge mobilization process per se. HTA's purpose is to solve a problem by mobilizing the types of evidence required and the concerned actors, in order to support political, organizational or clinical decision-making. HTA relies on the

    Full Text Available Currently, the field of smart-* (home, city, health, tourism, etc. is naturally heterogeneous and multimedia oriented. In such a domain, there is an increasing usage of heterogeneous mobile devices, as well as captors transmitting data (IoT. They are highly connected and can be used for many different services, such as to monitor, to analyze and to display information to users. In this context, data management and adaptation in real time are becoming a challenging task. More precisely, at one time, it is necessary to handle in a dynamic, intelligent and transparent framework various data provided by multiple devices with several modalities. This paper presents a Kali-Smart platform, which is an autonomic semantic-based context-aware platform. It is based on semantic web technologies and a middleware providing autonomy and reasoning facilities. Moreover, Kali-Smart is generic and, as a consequence, offers to users a flexible infrastructure where they can easily control various interaction modalities of their own situations. An experimental study has been made to evaluate the performance and feasibility of the proposed platform.

    2014-05-01

    Mobile phone sensing is a critical underpinning of pervasive mobile computing, and is one of the key factors for improving people's quality of life in modern society via collective utilization of the on-board sensing capabilities of people's smartphones. The increasing demands for sensing services and ambient awareness in mobile environments highlight the necessity of active participation of individual mobile users in sensing tasks. User incentives for such participation have been continuously offered from an application-centric perspective, i.e., as payments from the sensing server, to compensate users' sensing costs. These payments, however, are manipulated to maximize the benefits of the sensing server, ignoring the runtime flexibility and benefits of participating users. This paper presents a novel framework of user-centric incentive design, and develops a universal sensing platform which translates heterogenous sensing tasks to a generic sensing plan specifying the task-independent requirements of sensing performance. We use this sensing plan as input to reduce three categories of sensing costs, which together cover the possible sources hindering users' participation in sensing.

    A new spherical mobile robot BHQ-1 is designed. The spherical robot is driven by two internally mounted motors that induce the ball to move straight and turn around on a flat surface. A dynamic model of the robot is developed with Lagrange method and factors affecting the driving torque of two motors are analyzed. The relationship between the turning radius of the robot and the length of two links is discussed in order to optimize its mechanism design. Simulation and experimental results demonstrate the good controllability and motion performance of BHQ-1.

    Self-management is critical to achieving diabetes treatment goals. Mobile phones and Bluetooth® can supportself-management and lifestyle changes for chronic diseases such as diabetes. A mobile health (mHealth) research platform--the Few Touch Application (FTA)--is a tool designed to support the self-management of diabetes. The FTA consists of a mobile phone-based diabetes diary, which can be updated both manually from user input and automatically by wireless data transfer, and which provides personalized decision support for the achievement of personal health goals. Studies and applications (apps) based on FTAs have included: (1) automatic transfer of blood glucose (BG) data; (2) short message service (SMS)-based education for type 1diabetes (T1DM); (3) a diabetes diary for type 2 diabetes (T2DM); (4) integrating a patient diabetes diary with health care (HC) providers; (5) a diabetes diary for T1DM; (6) a food picture diary for T1DM; (7) physical activity monitoring for T2DM; (8) nutrition information for T2DM; (9) context sensitivity in mobile self-help tools; and (10) modeling of BG using mobile phones. We have analyzed the performance of these 10 FTA-based apps to identify lessons for designing the most effective mHealth apps. From each of the 10 apps of FTA, respectively, we conclude: (1) automatic BG data transfer is easy to use and provides reassurance; (2) SMS-based education facilitates parent-child communication in T1DM; (3) the T2DM mobile phone diary encourages reflection; (4) the mobile phone diary enhances discussion between patients and HC professionals; (5) the T1DM mobile phone diary is useful and motivational; (6) the T1DM mobile phone picture diary is useful in identifying treatment obstacles; (7) the step counter with automatic data transfer promotes motivation and increases physical activity in T2DM; (8) food information on a phone for T2DM should not be at a detailed level; (9) context sensitivity has good prospects and is possible to

    Eckman, Molly; Gorski, Irena; Mehta, Khanjan

    Mobile health, or mHealth, technology has the potential to improve health care access in the developing world. However, the majority of mHealth projects do not expand beyond the pilot stage. A core reason why is because they do not account for the individual needs and wants of those involved. A collaborative approach is needed to integrate the perspectives of all stakeholders into the design and operation of mHealth endeavours. Design thinking is a methodology used to develop and evaluate novel concepts for systems. With roots in participatory processes and self-determined pathways, design thinking provides a compelling framework to understand and apply the needs of diverse stakeholders to mHealth project development through a highly iterative process. The methodology presented in this article provides a structured approach to apply design thinking principles to assess the feasibility of novel mHealth endeavours during early conceptualisation.

    Prévost, Laurent; Liechti, Olivier; Lyons, Michael J.

    This paper describes the design, implementation, and initial testing of a reusable platform for the creation of pervasive games with geo-localization services. We concentrate on role-playing games built by combining several types of simpler mini-games having three major components: Quests; Collectables; and Non-player characters (NPC). Quests encourage players to be active in their physical environment and take part in collaborative play; Collectables provide motivation; and NPCs enable player-friendly interaction with the platform. Each of these elements poses different technical requirements, which were met by implementing the gaming platform using the inTrack pervasive middle-ware being developed by our group. Several sample games were implemented and tested within the urban environment of Kyoto, Japan, using gaming clients running on mobile phones from NTT DoCoMo, Japan’s largest mobile provider.

The SPML provides a mobile platform that schools, universities, and communities can use to give students and staff access to laboratory environments where dedicated laboratories are not available. The lab includes equipment like 3D printers, computers, and soldering stations. The primary power source of the system is solar PV which allows the laboratory to be operated in places where the grid power is not readily available or not sufficient to power all the equipment. The main system components include PV panels, junction box, battery, charge controller, and inverter. Not only is it used to teach students and staff how to use the lab equipment, but it is also a great tool to educate the public about solar PV technologies.

  15. Context sensitive trust based geographic opportunistic routing in mobile ad hoc networks

    A RAJESH; N MOHAN KUMAR

    2016-11-01

    Position based opportunistic routing (POR) is a stateless, robust, and reliable geographic routing protocol in Mobile AdHoc NETwork (MANET). The opportunistic routing embraces broadcast property of wireless channels and utilizes it for opportunistic forwarding. Both the malicious node behavior and the backupnodes’ behavior are equally treated as malicious in the existing misbehavior detection mechanisms. Hence, incorporating a general trust model in POR is not combative with routing attacks. It is necessary to determine whether the misbehavior is likely a result of malicious activity or due to the backup scenario of opportunistic forwarding. On the other hand, if context-sensitive trust information is available on every node, it ensures a fair decision making and also supports secured routing in an opportunistic approach. This work investigates the utilization of context attributes along with generic trust model to allow POR for secure and reliable data forwarding. This paper introduces context-sensitive trust for choosing the data forwarding node in POR (CPOR) to assist opportunistic routing in selecting the trusted optimal data forwarding node and to cope with both security and reliability of communications. The proposed work exercises both coarse- and fine-grained trust evaluation to strengthen the trustworthiness. The coarse-grained trust measure includes positive progress per hop and behavioral attribute of the nodes in terms of routing service. The fine-grained trust evaluation differs the opportunistic routing environment from the adverse scenarios and aids the source node such that it builds a highly trusted positive progress set using contextual attributes. The fine-grained trust evaluation deduces the ideal contextual information such as the link quality, battery energy, and the backup service to determine the accurate trust value of nodes. As a result, it involves optimal routes and enables CPOR to maintain the routingperformance equal to the POR even

    2016-11-03

    Both mobile apps and responsive-design websites (web apps) can be used to deliver mobile health (mHealth) interventions, but it can be difficult to discern which to use in research. The goal of this paper is to present four case studies from behavioral interventions that developed either a mobile app or a web app for research and present an information table to help researchers determine which mobile option would work best for them. Four behavioral intervention case studies (two developed a mobile app, and two developed a web app) presented include time, cost, and expertise. Considerations for adopting a mobile app or a web app-such as time, cost, access to programmers, data collection, security needs, and intervention components- are presented. Future studies will likely integrate both mobile app and web app modalities. The considerations presented here can help guide researchers on which platforms to choose prior to starting an mHealth intervention.

    2012-07-01

    Full Text Available Mobile and wireless (M&W technologies have great potential to improve process efficiency and effectiveness within retail stores, but their application is still very limited. One of the main reasons explaining this situation is considered to be the lack of confidence in the actual benefits and, therefore, in the return on investment. As a matter of facts, activities in this context are characterised by great variety and non‐standardised execution and as such the assessment of the costs and benefits of M&W solutions is more difficult than for the upstream tiers of the fast moving consumer goods supply chain (e.g., distribution centres. This paper attempts to provide a contribution for researchers and practitioners by presenting an analytical model to assess the profitability related to investments in multiple M&W solutions for retail stores, thus supporting the decision‐ making process.

    2011-01-01

    In this paper we argue that the set of wireless, mobile devices (e.g., portable telephones, tablet PCs, GPS navigators, media players) commonly used by human users enables the construction of what we term a digital ecosystem, i.e., an ecosystem constructed out of so-called digital organisms (see below), that can foster the development of novel distributed services. In this context, a human user equipped with his/her own mobile devices, can be though of as a digital organism (DO), a subsystem characterized by a set of peculiar features and resources it can offer to the rest of the ecosystem for use from its peer DOs. The internal organization of the DO must address issues of management of its own resources, including power consumption. Inside the DO and among DOs, peer-to-peer interaction mechanisms can be conveniently deployed to favor resource sharing and data dissemination. Throughout this paper, we show that most of the solutions and technologies needed to construct a digital ecosystem are already availabl...

    Martini, Maria G; Hewage, Chaminda T E R

    2010-01-01

    The most recent network technologies are enabling a variety of new applications, thanks to the provision of increased bandwidth and better management of Quality of Service. Nevertheless, telemedical services involving multimedia data are still lagging behind, due to the concern of the end users, that is, clinicians and also patients, about the low quality provided. Indeed, emerging network technologies should be appropriately exploited by designing the transmission strategy focusing on quality provision for end users. Stemming from this principle, we propose here a context-aware transmission strategy for medical video transmission over WiMAX systems. Context, in terms of regions of interest (ROI) in a specific session, is taken into account for the identification of multiple regions of interest, and compression/transmission strategies are tailored to such context information. We present a methodology based on H.264 medical video compression and Flexible Macroblock Ordering (FMO) for ROI identification. Two different unequal error protection methodologies, providing higher protection to the most diagnostically relevant data, are presented.

    Wu, Fong-Gong; Ma, Min-Yuan; Chang, Ro-Han

    2009-09-01

    This study utilized a user-centered design approach as the foundation for a new Assistive Device (AD) design process. Observation and evaluation results from a Usability Context Analysis (UCA) was used to improve the analysis of Strengths, Weaknesses, Opportunities and Threats (SWOT Analysis) and the matrix of Threats, Opportunities, Weaknesses, and Strengths (TOWS matrix), resulting in two assistive device design methods named AD-SWOT and AD-TOWS. Thus, an AD-design process, tailored for designing assistive devices, was both established and tested. Owing to the information gained from using the design processes and evaluating product efficiency with various cases in the early part of the research, it was decided to use the AD-design process for the entire design process. Using this process, an adjustable hair washer for physically disabled individuals to wash their hair using normal postures was developed. Furthermore, the method derived in this study can also be applied to users suffering from single-sided shoulder-joint mobility disabilities, such as frontal flexion, scapular plan elevation, and restricted abductors.

  11. Family migration and mobility sequences in the United States: Spatial mobility in the context of the life course

    Directory of Open Access Journals (Sweden)

    Suzanne Davies Withers

    2007-12-01

    Full Text Available Significant changes in family composition in the past quarter-century raise important questions about life-course outcomes embedded in these family changes, especially in relation to the migratory and mobility patterns of individuals and families. The classic distinction between long-distance/employment and short-distance/housing-related moves may be eroding. Patterns of movement appear much less dichotomous and more diverse as family structures become more diverse. Using the Panel Study of Income Dynamics this study shows that the previous research, which suggested relatively simple links between long-distance and short-distance moves, is an over-simplification. Moreover, there is much more unintended movement at both migratory and mobility scales suggesting the economic models of employment migration may be missing important family dynamics in the migration mobility process.

    The inability to seamlessly disseminate data securely over a high-integrity, wireless broadband network has been identified as a primary technical barrier to providing an order-of-magnitude increase in aviation capacity and safety. Secure, autonomous communications to and from aircraft will enable advanced, automated, data-intensive air traffic management concepts, increase National Air Space (NAS) capacity, and potentially reduce the overall cost of air travel operations. For the first time ever, secure, mobile, network technology was designed, developed, and demonstrated with state-ofthe- art protocols and applications by a diverse, cooperative Government-industry team led by the NASA Glenn Research Center. This revolutionary technology solution will make fundamentally new airplane system capabilities possible by enabling secure, seamless network connections from platforms in motion (e.g., cars, ships, aircraft, and satellites) to existing terrestrial systems without the need for manual reconfiguration. Called Mobile Router, the new technology autonomously connects and configures networks as they traverse from one operating theater to another. The Mobile Router demonstration aboard the Neah Bay, a U.S. Coast Guard vessel stationed in Cleveland, Ohio, accomplished secure, seamless interoperability of mobile network systems across multiple domains without manual system reconfiguration. The Neah Bay was chosen because of its low cost and communications mission similarity to low-Earth-orbiting satellite platforms. This technology was successfully advanced from technology readiness level (TRL) 2 (concept and/or application formation) to TRL 6 (system model or prototype demonstration in a relevant environment). The secure, seamless interoperability offered by the Mobile Router and encryption device will enable several new, vehicle-specific and systemwide technologies to perform such things as remote, autonomous aircraft performance monitoring and early detection and

    Full Text Available In order to accomplish exploration missions in complex environments, a new type of robot has been designed. By analyzing the characteristics of typical moving systems, a new mobile system which is named wheel-tracked moving system (WTMS has been presented. Then by virtual prototype simulation, the new system’s ability to adapt complex environments has been verified. As the curve of centroid acceleration changes in large amplitude in this simulation, ride performance of this robot has been studied. Firstly, a simplified dynamic model has been established, and then by affecting factors analysis on ride performance, an optimization model for suspension parameters has been presented. Using NSGA-II method, a set of nondominated solutions for suspension parameters has been gotten, and by weighing the importance of the objective function, an optimal solution has been selected to be applied on suspension design. As the wheel-tracked exploration robot has been designed and manufactured, the property test has been conducted. By testing on physical prototype, the robot’s ability to surmount complex terrain has been verified. Design of the wheel-tracked robot will provide a stable platform for field exploration tasks, and in addition, the certain configuration and suspension parameters optimization method will provide reference to other robot designs.

  4. Antenna Design Considerations for the Advanced Extravehicular Mobility Unit

    Science.gov (United States)

    Bakula, Casey J.; Theofylaktos, Onoufrios

    2015-01-01

    NASA is designing an Advanced Extravehicular Mobility Unit (AEMU)to support future manned missions beyond low-Earth orbit (LEO). A key component of the AEMU is the communications assembly that allows for the wireless transfer of voice, video, and suit telemetry. The Extravehicular Mobility Unit (EMU) currently used on the International Space Station (ISS) contains a radio system with a single omni-directional resonant cavity antenna operating slightly above 400 MHz capable of transmitting and receiving data at a rate of about 125 kbps. Recent wireless communications architectures are calling for the inclusion of commercial wireless standards such as 802.11 that operate in higher frequency bands at much higher data rates. The current AEMU radio design supports a 400 MHz band for low-rate mission-critical data and a high-rate band based on commercial wireless local area network (WLAN) technology to support video, communication with non-extravehicular activity (EVA) assets such as wireless sensors and robotic assistants, and a redundant path for mission-critical EVA data. This paper recommends the replacement of the existing EMU antenna with a new antenna that maintains the performance characteristics of the current antenna but with lower weight and volume footprints. NASA has funded several firms to develop such an antenna over the past few years, and the most promising designs are variations on the basic patch antenna. This antenna technology at UHF is considered by the authors to be mature and ready for infusion into NASA AEMU technology development programs.

    Full Text Available In cloud computing environments, context information is continuously created by context providers and consumed by the applications on mobile devices. An important characteristic of cloud - based context aware services is meeting the service level agreements (SLAs to deliver a certain quality of service (Qos , s uch as guarantees on response time or price. The response time to a request of context - aware software is affected by loading extensive context data from multiple resources on the chosen server. Therefore, the speed of such software would be decreased durin g execution time. Hence, proper scheduling of such services is indispensable because the customers are faced with time constraints. In this research, a new schedul ing algorithm for context aware services is proposed which is based on classifying similar co ntext consumers and dynamically scoring the requests to improve the performance of the server hosting highly - requested context - aware software while reducing costs of cloud provider. The approach is evaluated via simulation and comparison with gi - FIFO sched uling algorithm. Experimental results demonstrate the efficiency of the proposed app roach

    ) and the surrounding nesting area (rural area). Preparing for the outdoor application of mobile MSDs we tested their accuracy and performance between several MSDs and reliable sophisticated devices under laboratory conditions. We found that variations mainly depend on the device design and technology (e.g. active/passive ventilation). The standard deviation of the temperature records was quite stable over the whole range of values and the MSDs proved to be applicable for the purpose of our study. In conclusion the benefit of integrating mobile data and micrometeorological predictions is manifold. Mobile data can be used for the investigation of personal exposure in the context of heat stress and for the verification and training of micrometeorological models. Otherwise, model predictions can identify local areas of special climate interest where additional mobile measurements would be beneficial to provide new information for mitigation and adaptation actions.

  4. Design of the next generation cognitive mobile ad hoc networks

    Science.gov (United States)

    Amjad, Ali; Wang, Huiqiang; Chen, Xiaoming

    Cognition capability has been seen by researchers as the way forward for the design of next generation of Mobile Ad Hoc Networks (MANETs). The reason why a cognitive paradigm would be more suited to a MANET is because MANETs are highly dynamic networks. The topology may change very frequently during the operation of a MANET. Traffic patterns in MANETs can vary from time to time depending on the need of the users. The size of a MANET and node density is also very dynamic and may change without any predictable pattern. In a MANET environment, most of these parameters may change very rapidly and keeping track of them manually would be very difficult. Previous studies have shown that the performance of a certain routing approach in MANETs is dependent on the size of the network and node density. The choice of whether to use a reactive or proactive routing approach comes down to the network size parameter. Static or offline approaches to fine tune a MANET to achieve certain performance goals is hence not very productive as a lot of these parameters keep changing during the course of operation of MANETs. Similarly, the performance of MANETs would improve greatly if the MAC layer entity could operate in a more flexible manner. In this paper we propose a cognitive MANET design that will ensure that all these dynamic parameters are automatically monitored and decisions are based on the current status of these parameters.

    1993-01-01

    With the collapse of the former Soviet Union and the emergence of the United Nations actively pursuing a peace keeping role in world affairs, the United States has been forced into a position as the world's leading peace enforcer. It is still a very dangerous world with seemingly never ending ideological, territorial, and economic disputes requiring the U.S. to maintain a credible deterrent posture in this uncertain environment. This has created an urgent need to rapidly transport large numbers of troops and equipment from the continental United States (CONUS) to any potential world trouble spot by means of a global range/mobility transport aircraft. The most recent examples being Operation Desert Shield/Storm and Operation Restore Hope. To meet this challenge head-on, a request for proposal (RFP) was developed and incorporated into the 1992/1993 AIAA/McDonnell Douglas Corporation Graduate Team Aircraft Design Competition. The RFP calls for the conceptual design and justification of a large aircraft capable of power projecting a significant military force without surface transportation reliance.

    2017-03-01

    Full Text Available Software technology is constantly evolving and therefore the development of applications requires adapting software components and applications in order to be aligned to new paradigms such as Pervasive Computing, Cloud Computing and Internet of Things. In particular, many desktop software components need to be migrated to mobile technologies. This migration faces many challenges due to the proliferation of different mobile platforms. Developers usually make applications tailored for each type of device expending time and effort. As a result, new programming languages are emerging to integrate the native behaviors of the different platforms targeted in development projects. In this direction, the Haxe language allows writing mobile applications that target all major mobile platforms. Novel technical frameworks for information integration and tool interoperability such as Architecture-Driven Modernization (ADM proposed by the Object Management Group (OMG can help to manage a huge diversity of mobile technologies. The Architecture-Driven Modernization Task Force (ADMTF was formed to create specifications and promote industry consensus on the modernization of existing applications. In this work, we propose a migration process from C/C++ software to different mobile platforms that integrates ADM standards with Haxe. We exemplify the different steps of the process with a simple case study, the migration of “the Set of Mandelbrot” C++ application. The proposal was validated in Eclipse Modeling Framework considering that some of its tools and run-time environments are aligned with ADM standards.

    Zhu, Egui; Lilienthal, Anneliese; Shluzas, Lauren Aquino; Masiello, Italo; Zary, Nabil

    2015-09-18

    Augmented reality (AR) is increasingly used across a range of subject areas in health care education as health care settings partner to bridge the gap between knowledge and practice. As the first contact with patients, general practitioners (GPs) are important in the battle against a global health threat, the spread of antibiotic resistance. AR has potential as a practical tool for GPs to combine learning and practice in the rational use of antibiotics. This paper was driven by learning theory to develop a mobile augmented reality education (MARE) design framework. The primary goal of the framework is to guide the development of AR educational apps. This study focuses on (1) identifying suitable learning theories for guiding the design of AR education apps, (2) integrating learning outcomes and learning theories to support health care education through AR, and (3) applying the design framework in the context of improving GPs' rational use of antibiotics. The design framework was first constructed with the conceptual framework analysis method. Data were collected from multidisciplinary publications and reference materials and were analyzed with directed content analysis to identify key concepts and their relationships. Then the design framework was applied to a health care educational challenge. The proposed MARE framework consists of three hierarchical layers: the foundation, function, and outcome layers. Three learning theories-situated, experiential, and transformative learning-provide foundational support based on differing views of the relationships among learning, practice, and the environment. The function layer depends upon the learners' personal paradigms and indicates how health care learning could be achieved with MARE. The outcome layer analyzes different learning abilities, from knowledge to the practice level, to clarify learning objectives and expectations and to avoid teaching pitched at the wrong level. Suggestions for learning activities and the

    Unique characteristics of nursing homes (NHs) contribute to high rates of inappropriate antibiotic use for asymptomatic bacteriuria (ASB), a benign condition. A mobile clinical decision support system (CDSS) may support NH staff in differentiating urinary tract infections (UTI) from ASB and reducing antibiotic days. We used Goal-Directed Design to: 1) Characterize information needs for UTI identification and management in NHs; 2) Develop UTI Decide, a mobile CDSS prototype informed by personas and scenarios of use constructed from Aim 1 findings; 3) Evaluate the UTI Decide prototype with NH staff. Focus groups were conducted with providers and nurses in NHs in Denver, Colorado (n= 24). Qualitative descriptive analysis was applied to focus group transcripts to identify information needs and themes related to mobile clinical decision support for UTI identification and management. Personas representing typical end users were developed; typical clinical context scenarios were constructed using information needs as goals. Usability testing was performed using cognitive walk-throughs and a think-aloud protocol. Four information needs were identified including guidance regarding resident assessment; communication with providers; care planning; and urine culture interpretation. Design of a web-based application incorporating a published decision support algorithm for evidence-based UTI diagnoses proceeded with a focus on nursing information needs during resident assessment and communication with providers. Certified nursing assistant (CNA) and registered nurse (RN) personas were constructed in 4 context scenarios with associated key path scenarios. After field testing, a high fidelity prototype of UTI Decide was completed and evaluated by potential end users. Design recommendations and content recommendations were elicited. Goal-Directed Design informed the development of a mobile CDSS supporting participant-identified information needs for UTI assessment and communication

    Directory of Open Access Journals (Sweden)

    Yunsik Son

    2017-01-01

    Full Text Available Several location-based services (LBSs have been recently developed for smartphones. Among these are proactive LBSs, which provide services to smartphone users by periodically collecting background logs. However, because they consume considerable battery power, they are not widely used for various LBS-based services. Battery consumption, in particular, is a significant issue on account of the characteristics of mobile systems. This problem involves a greater service restriction when performing complex operations. Therefore, to successfully enable various services based on location, this problem must be solved. In this paper, we introduce a technique to automatically generate a customized service optimizer for each application, service type, and platform using location and situation information. By using the proposed technique, energy and computing resources can be more efficiently employed for each service. Thus, users should receive more effective LBSs on mobile devices, such as smartphones.

    2015-08-26

    The increasing pervasiveness of mobile technologies has given potential to transform healthcare by facilitating clinical management using software applications. These technologies may provide valuable tools in sexual health care and potentially overcome existing practical and cultural barriers to routine testing for sexually transmitted infections. In order to inform the design of a mobile health application for STIs that supports self-testing and self-management by linking diagnosis with online care pathways, we aimed to identify the dimensions and range of preferences for user interface design features among young people. Nine focus group discussions were conducted (n = 49) with two age-stratified samples (16 to 18 and 19 to 24 year olds) of young people from Further Education colleges and Higher Education establishments. Discussions explored young people's views with regard to: the software interface; the presentation of information; and the ordering of interaction steps. Discussions were audio recorded and transcribed verbatim. Interview transcripts were analysed using thematic analysis. Four over-arching themes emerged: privacy and security; credibility; user journey support; and the task-technology-context fit. From these themes, 20 user interface design recommendations for mobile health applications are proposed. For participants, although privacy was a major concern, security was not perceived as a major potential barrier as participants were generally unaware of potential security threats and inherently trusted new technology. Customisation also emerged as a key design preference to increase attractiveness and acceptability. Considerable effort should be focused on designing healthcare applications from the patient's perspective to maximise acceptability. The design recommendations proposed in this paper provide a valuable point of reference for the health design community to inform development of mobile-based health interventions for the diagnosis

    2012-05-01

    It is commonly argued that social mobility rates are influenced by economic and political conditions. Nevertheless, research on this issue has tended to be hindered by two limitations that make it difficult to draw strong conclusions about contextual effects: (1) seldom have country-level and individual-level influences been tested simultaneously, and (2) only rarely have data more recent than the 1970s been employed. We improve on previous research by employing multilevel models fitted to relatively recent survey data collected from 20 modern societies by the International Social Survey Program (ISSP) and national-level characteristics derived from various official sources. Our findings demonstrate systematic cross-national variation in the association between the occupational status of respondents and their fathers. Consistent with the industrialization thesis, this variation is positively associated with per-capita GDP, suggesting that more affluent nations are characterized by more open and fluid stratification structures. Our results also suggest the importance of political regimes and migration for social mobility. In contrast, economic inequality appears to explain very little of the cross-national variation in mobility rates. Copyright © 2012 Elsevier Inc. All rights reserved.

  15. Context-Aware Mobile Sensors for Sensing Discrete Events in Smart Environment

    Directory of Open Access Journals (Sweden)

    Awais Ahmad

    2016-01-01

    Full Text Available Over the last few decades, several advancements in the field of smart environment gained importance, so the experts can analyze ideas for smart building based on embedded systems to minimize the expense and energy conservation. Therefore, propelling the concept of smart home toward smart building, several challenges of power, communication, and sensors’ connectivity can be seen. Such challenges distort the interconnectivity between different technologies, such as Bluetooth and ZigBee, making it possible to provide the continuous connectivity among different objects such as sensors, actuators, home appliances, and cell phones. Therefore, this paper presents the concept of smart building based on embedded systems that enhance low power mobile sensors for sensing discrete events in embedded systems. The proposed scheme comprises system architecture that welcomes all the mobile sensors to communicate with each other using a single platform service. The proposed system enhances the concept of smart building in three stages (i.e., visualization, data analysis, and application. For low power mobile sensors, we propose a communication model, which provides a common medium for communication. Finally, the results show that the proposed system architecture efficiently processes, analyzes, and integrates different datasets efficiently and triggers actions to provide safety measurements for the elderly, patients, and others.

  11. Design of an Agent Based Context Driven Focused Crawler

    Directory of Open Access Journals (Sweden)

    A. K. Sharma

    2009-07-01

    Full Text Available A focused crawler downloads web pages that are relevant to auser specified topic. Most of the existing focused crawlers arekeyword driven and do not take into account the contextassociated with the keywords. This leads to retrieval of a largenumber of web pages irrespective of the fact whether they arelogically related. Thus, the keyword based strategy alone isnot sufficient for the design of a focused crawler as contextrelevance is more important as far as the user’s requirementis concerned. This paper proposes the design of a contextdriven focused crawler (CDFC that searches and downloadsonly highly related web pages, thereby reducing the networktraffic. It also employs a category tree which is a flexible userinterface showing the broad categories of the topics on theweb. Since CDFC downloads only the relevant and credibledocuments, a very small number in comparison, the proposeddesign significantly reduces the storage space at the searchengine side.

    Loose, Harald; Lemke, Christiane; Papazov, Chavdar

    2006-02-01

    This paper deals with intelligent mobile platforms connected to a camera controlled by a small hardware-platform called RCUBE. This platform is able to provide features of a typical actuator-sensor board with various inputs and outputs as well as computing power and image recognition capabilities. Several intelligent autonomous RCBUE devices can be equipped and programmed to participate in the BOSPORUS network. These components form an intelligent network for gathering sensor and image data, sensor data fusion, navigation and control of mobile platforms. The RCUBE platform provides a standalone solution for image processing, which will be explained and presented. It plays a major role for several components in a reference implementation of the BOSPORUS system. On the one hand, intelligent cameras will be positioned in the environment, analyzing the events from a fixed point of view and sharing their perceptions with other components in the system. On the other hand, image processing results will contribute to a reliable navigation of a mobile system, which is crucially important. Fixed landmarks and other objects appropriate for determining the position of a mobile system can be recognized. For navigation other methods are added, i.e. GPS calculations and odometers.

    We present a video management system comprising a video server and a mobile camera-phone application called MobiCon, which allows users to capture videos, annotate them with metadata, specify digital rights management (DRM) settings, upload the videos over the cellular network, and share them with others. Once stored in the video server, users can then search their personal video collection via a web interface, and watch the video clips using a wide range of terminals. We describe the MobiCon architecture, compare it with related work, provide an overview of the video server, and illustrate a typical user scenario from the point of capture to video sharing and video searching. Our work takes steps forward in advancing the mobile camera-phone from a video playback device to a video production tool. We summarize field trial results conducted in the area of Oulu, Finland, which demonstrate that users can master the application quickly, but are unwilling to perform extensive manual annotations. Based on the user trial results and our own experience, we present future development directions for MobiCon, in particular, and the video management architecture, in general.

    Hye-Kyoung Jeon; Jung-Hyun Lee; Kee-Wook Rim; Yang-Jae Park

    2007-01-01

    This paper presents a system to alert of dangerous a child situation of a child by applying context information collected from a home network to ontology that is capable of inference. Radio frequency Identification (RFID) and sensors were used for the configuration of a home network, to obtain the raw data to convert into context information. To express the ontology, web ontology language (OWL) was used to provide the inference of context information. Then, simple object access protocol (SOAP) messages were used to notify of the dangerous situations that a child may be involved in via mobile devices. The proposed system consists of Context Manager, Service Manager, and Notification Manager. The child's safety management system can proactively detect the context data of a child on the basis of context awareness. In the experiment, the Jena 2.0 by ontology reasoner and the OSGi(Open Service Gateway initiative) Gateway developed using open source software Knopflerfish 1.3.3 were used to implement the service frame work.

  12. Context-driven discovery of gene cassettes in mobile integrons using a computational grammar

    Directory of Open Access Journals (Sweden)

    Schaeffer Jaron

    2009-09-01

    Full Text Available Abstract Background Gene discovery algorithms typically examine sequence data for low level patterns. A novel method to computationally discover higher order DNA structures is presented, using a context sensitive grammar. The algorithm was applied to the discovery of gene cassettes associated with integrons. The discovery and annotation of antibiotic resistance genes in such cassettes is essential for effective monitoring of antibiotic resistance patterns and formulation of public health antibiotic prescription policies. Results We discovered two new putative gene cassettes using the method, from 276 integron features and 978 GenBank sequences. The system achieved κ = 0.972 annotation agreement with an expert gold standard of 300 sequences. In rediscovery experiments, we deleted 789,196 cassette instances over 2030 experiments and correctly relabelled 85.6% (α ≥ 95%, E ≤ 1%, mean sensitivity = 0.86, specificity = 1, F-score = 0.93, with no false positives. Error analysis demonstrated that for 72,338 missed deletions, two adjacent deleted cassettes were labeled as a single cassette, increasing performance to 94.8% (mean sensitivity = 0.92, specificity = 1, F-score = 0.96. Conclusion Using grammars we were able to represent heuristic background knowledge about large and complex structures in DNA. Importantly, we were also able to use the context embedded in the model to discover new putative antibiotic resistance gene cassettes. The method is complementary to existing automatic annotation systems which operate at the sequence level.

  13. Integrating RFID technique to design mobile handheld inventory management system

    Science.gov (United States)

    Huang, Yo-Ping; Yen, Wei; Chen, Shih-Chung

    2008-04-01

    An RFID-based mobile handheld inventory management system is proposed in this paper. Differing from the manual inventory management method, the proposed system works on the personal digital assistant (PDA) with an RFID reader. The system identifies electronic tags on the properties and checks the property information in the back-end database server through a ubiquitous wireless network. The system also provides a set of functions to manage the back-end inventory database and assigns different levels of access privilege according to various user categories. In the back-end database server, to prevent improper or illegal accesses, the server not only stores the inventory database and user privilege information, but also keeps track of the user activities in the server including the login and logout time and location, the records of database accessing, and every modification of the tables. Some experimental results are presented to verify the applicability of the integrated RFID-based mobile handheld inventory management system.

The discussion is methodologically structured into three complementary lines of analysis results from documentary research accompanied by field study, visits, participations in meetings, inter-institutional forums, public hearings, thematic debates, in addition to literature review. In the first analysis axis, we discuss the current legislation in Brazil, the construction of migration policy at the municipal level and civil society articulations about human mobility, understood as a fundamental right. In the second, we discuss people care services, families and groups in migratory situation in São Paulo, SP. Finally, on the third axis, we discuss the cultural developments in social occupational therapy for professional action and training in the field of human mobility. As a result it was observed that the current panorama poses new professional challenges, forcing the occupational therapist to review its technical-political position face to the new realities of the contemporary world.

    Visual coherence between virtual and real objects is a major issue in creating convincing augmented reality (AR) applications. To achieve this seamless integration, actual light conditions must be determined in real time to ensure that virtual objects are correctly illuminated and cast consistent shadows. In this paper, we propose a novel method to estimate daylight illumination and use this information in outdoor AR applications to render virtual objects with coherent shadows. The illumination parameters are acquired in real time from context-aware live sensor data. The method works under unprepared natural conditions. We also present a novel and rapid implementation of a state-of-the-art skylight model, from which the illumination parameters are derived. The Sun's position is calculated based on the user location and time of day, with the relative rotational differences estimated from a gyroscope, compass and accelerometer. The results illustrated that our method can generate visually credible AR scenes with consistent shadows rendered from recovered illumination.

    We present a hybrid systems solution to the problem of trajectory tracking for a four-wheel steered four-wheel driven mobile robot. The robot is modelled as a non-holonomic dynamic system subject to pure rolling, no-slip constraints. Under normal driving conditions, a nonlinear trajectory tracking...... feedback control law based on dynamic feedback linearization is sufficient to stabilize the system and ensure asymptotically stable tracking. Transitions to other modes are derived systematically from this model, whenever the configuration space of the controlled system has some fundamental singular points.......

    2015-01-01

    Full Text Available Kinematic and dynamic modelling and corresponding control design of a four-wheel-independent steering and four-wheel-independent driving (4WIS4WID mobile robot are presented in this study. Different from the differential or car-like mobile robot, the 4WIS4WID mobile robot is controlled by four steering and four driving motors, so the control scheme should possess the ability to integrate and manipulate the four independent wheels. A trajectory tracking control scheme is developed for the 4WIS4WID mobile robot, where both non-linear kinematic control and dynamic sliding-mode control are designed. All of the stabilities of the kinematic and dynamic control laws are proved by Lyapunov stability analysis. Finally, the feasibility and validity of the proposed trajectory tracking control scheme are confirmed through computer simulations.

    Full Text Available This study explores the potential of smart mobile services to enhance online and offline shopping. Three prototypes were designed and implemented on smart phones and smart watches. Thirty young adults participated in the experiment to evaluate these prototypes. The results indicate that satisfaction with smart services is influenced by characteristics such as innovativeness, current shopping behavior, and design of prototypes. Positive feedback was generally given towards smart mobile services, but there were mixed attitudes towards key features. First, participants with a utilitarian motivation liked the indoor navigation feature, but those with a hedonic motivation enjoyed exploration. Second, in the area of big data, participants wanted more control over recommendations and more protection of privacy. Third, participants wanted to make mobile payments but were concerned about security. Finally, developers of new technology for smart mobile services should consider practicability.

This requires the capability to maneuver in a complex unknown environment. The mobile robot uses intuitive fuzzy rules and is expected to reach a specific target or follow a prespecified trajectory while moving among unforeseen obstacles. The robot's mission depends on the choice of the task. In this paper, behavioral-based control architecture is adopted, and each local navigational task is analyzed in terms of primitive behaviors. Our approach is systematic and original in the sense that some of the fuzzy rules are not triggered in face of critical situations for which the stere

  18. SmartCanvas: Context-inferred Interpretation of Sketches for Preparatory Design Studies

    KAUST Repository

    Zheng, Youyi

    2016-05-27

    In early or preparatory design stages, an architect or designer sketches out rough ideas, not only about the object or structure being considered, but its relation to its spatial context. This is an iterative process, where the sketches are not only the primary means for testing and refining ideas, but also for communicating among a design team and to clients. Hence, sketching is the preferred media for artists and designers during the early stages of design, albeit with a major drawback: sketches are 2D and effects such as view perturbations or object movement are not supported, thereby inhibiting the design process. We present an interactive system that allows for the creation of a 3D abstraction of a designed space, built primarily by sketching in 2D within the context of an anchoring design or photograph. The system is progressive in the sense that the interpretations are refined as the user continues sketching. As a key technical enabler, we reformulate the sketch interpretation process as a selection optimization from a set of context-generated canvas planes in order to retrieve a regular arrangement of planes. We demonstrate our system (available at http:/geometry.cs.ucl.ac.uk/projects/2016/smartcanvas/) with a wide range of sketches and design studies. © 2016 The Author(s) Computer Graphics Forum © 2016 The Eurographics Association and John Wiley & Sons Ltd.

    Generally, mobile phone use one camera to catch the image, and it is hard to get stereo image pair. Adding a biprism array can help that get the image pair easily. So users can use their mobile phone to catch the stereo image anywhere by adding a biprism array, and if they want to get a normal image just remove it. Using biprism arrays will induce chromatic aberration. Therefore, we design a double biprism arrays to reduce chromatic aberration.

  5. The Design and Engineering of Mobile Data Services: Developing an Ontology Based on Business Model Thinking

    Science.gov (United States)

    Al-Debei, Mutaz M.; Fitzgerald, Guy

    This paper addresses the design and engineering problem related to mobile data services. The aim of the research is to inform and advise mobile service design and engineering by looking at this issue from a rigorous and holistic perspective. To this aim, this paper develops an ontology based on business model thinking. The developed ontology identifies four primary dimensions in designing business models of mobile data services: value proposition, value network, value architecture, and value finance. Within these dimensions, 15 key design concepts are identified along with their interrelationships and rules in the telecommunication service business model domain and unambiguous semantics are produced. The developed ontology is of value to academics and practitioners alike, particularly those interested in strategic-oriented IS/IT and business developments in telecommunications. Employing the developed ontology would systemize mobile service engineering functions and make them more manageable, effective, and creative. The research approach to building the mobile service business model ontology essentially follows the design science paradigm. Within this paradigm, we incorporate a number of different research methods, so the employed methodology might be better characterized as a pluralist approach.

    2013-10-01

    Against the background of considerable population ageing processes in rural areas, it is expected that access to the health care system in these regions will deteriorate. Within this context, the question arises as to whether elderly people have the ability to overcome increasing distances in order to receive adequate medical care. Hence the objective of this study is an in-depth analysis of the everyday mobility of elderly people living in rural areas. The empirical analysis is based on the German National Travel Survey "Mobilität in Deutschland 2008". Findings show that older women in particular experience limitations in their mobility options. Only 63% of mobility-impaired women (aged > 75 years) were mobile outside their homes, and only 37% had access to a car, which can be regarded as the crucial factor for being mobile. It follows that older and mobility-impaired women have to cope with everyday life under difficult conditions. In the context of the growing problem of access to the health care system in rural areas, the challenge is to ensure adequate primary health care for a large proportion of the immobile elderly.

    2012-03-01

    The committees for the current Dutch context-based innovation in secondary science education employed teachers to design context-based curriculum materials. A study on the learning of science teachers in design teams for context-based curriculum materials is presented in this paper. In a correlation study, teachers with (n = 25 and 840 students) and without (n = 8 and 184 students) context-based curriculum material design experience were compared on context-based competence. Context-based competence comprises context handling, regulation, emphasis, design, and school innovation. Context-based teaching competence was mapped using both qualitative and quantitative research methods in a composite instrument. Due to the differences in design team set-up for different science subjects, teachers with design experience from different science subjects were also compared on their context-based competence. It was found that teachers with design experience showed more context-based competence than their non-designing colleagues. Furthermore, teachers designing for biology showed more context-based competence than their peers from other science subjects.

    2017-04-01

    The application of mobile micro-sensing devices (MSDs) for human health and personal exposure monitoring (PEM) is an emerging topic of interest in urban air quality research. In the context of climate change, urban population growth and related anthropogenic activities, an increase is expected for the intensity of citizens' exposure to heat and particulate matter (PM). Therefore more focus on the small-scale perspective of spatio-temporal distribution of air quality parameters is important to complement fixed-monitoring site data. Mobile sensors for PEM are useful for both, the investigation of the local distribution of air quality and the personal exposure profiles of individuals moving within their activity spaces. An evaluation of MSDs' accuracy is crucial, before their sophisticated application in measurement campaigns. To detect variations of exposure at small scales, it is even more important to consider the accuracy of Global Positioning System (GPS) devices within different urban structure types (USTs). We present an assessment of the performance of GPS-based MSDs under indoor laboratory conditions and outdoor testing within different USTs. The aim was to evaluate the accuracy of several GPS devices and MSDs for heat and PM 2.5 in relation to reliable standard sensing devices as part of a PhD-project. The performance parameters are summary measures (mean value, standard deviation), correlation (Pearson r), difference measures (mean bias error, mean absolute error, index of agreement) and Bland-Altman plots. The MSDs have been tested in a climate chamber under constant temperature and relative humidity. For temperature MSDs reaction time was tested because of its relevance to detect temperature variations during mobile measurements. For interpretation of the results we considered the MSDs design and technology (e.g. passive vs. active ventilation). GPS-devices have been tested within low/high dense urban residential areas and low/high dense urban green areas

    Zhou, Ronggang; Feng, Caihong

    2017-01-01

    There is a rapidly growing body of literature on mobile video calling, which is a promising communication technology; however, little research has focused on user acceptance of mobile video calling, especially in different use contexts. This study explored factors (especially perceived enjoyment) influencing the intention of users to employ video calling in different contexts (a work and a leisure context) by applying the technology acceptance model (TAM) combined with the theory of planned behavior. The revised research model differentiated external factors (subjective norms and personal innovativeness) from internal factors (perceived usefulness, perceived ease of use (PEU), perceived enjoyment, and intention to use mobile video calling). In addition, the current study investigated predictors of perceived enjoyment across these two contexts. With the use of a structured questionnaire, participants were divided in two groups and completed self-report measures related to one context; a total of 386 student respondents' responses were analyzed. The results indicated that users' intentions were directly predicted by their perceived enjoyment of video calling (β ≥ 0.35) and the call's perceived usefulness (β ≥ 0.27) and PEU (β = 0.13, only for the leisure context), which jointly explained at least 55.6% of the variance in use intention. In addition to the effects of these predictors on mobile video calling use acceptance, an assessment of the moderating effects of different contexts indicated that perceived enjoyment played a more important role in influencing intention for the leisure context, while perceived usefulness appeared to be more important for the work context. This study's findings are important in that they provide strong support for the necessity of distinguishing among different types of contexts when predicting users' intentions to use video calling. Furthermore, the results showed that perceived enjoyment was most significantly influenced by

    It has become increasingly common to attribute part of the obesity epidemic to changes in the environment. Identification of a clear and obvious role for contextual risk factors has not yet been demonstrated. The objectives of this study were to explain differences in local overweight risk in two different urban settings and to explore sex-specific associations with estimated mobility patterns. Overweight was modeled within a multilevel framework using built environmental and socioeconomic contextual indicators and individual-level estimates of activity space exposure to fast-food restaurants (or exposure to visited places). Significant variations in local levels in overweight risk were observed. Physical and socioeconomic contexts explained more area-level differences in overweight among men than among women and among inhabitants of Montreal than among inhabitants of Quebec City. Estimated activity space exposure to fast-food outlets was significantly associated with overweight for men in Montreal. Local-level analyses are required to improve our understanding of contextual influences on obesity, including multiple influences in people's daily geographies.

    We explored the concept of design quality in relation to healthcare environments. In addition, we present a taxonomy that illustrates the wide range of terms used in connection with design quality in healthcare. High-quality physical environments can promote health and well-being. Developments in healthcare technology and methodology put high demands on the design quality of care environments, coupled with increasing expectations and demands from patients and staff that care environments be person centered, welcoming, and accessible while also supporting privacy and security. In addition, there are demands that decisions about the design of healthcare architecture be based on the best available information from credible research and the evaluation of existing building projects. The basic principles of Arksey and O'Malley's model of scoping review design were used. Data were derived from literature searches in scientific databases. A total of 18 articles and books were found that referred to design quality in a healthcare context. Design quality of physical healthcare environments involves three different themes: (i) environmental sustainability and ecological values, (ii) social and cultural interactions and values, and (iii) resilience of the engineering and building construction. Design quality was clarified herein with a definition. Awareness of what is considered design quality in relation to healthcare architecture could help to design healthcare environments based on evidence. To operationalize the concept, its definition must be clear and explicit and able to meet the complex needs of the stakeholders in a healthcare context, including patients, staff, and significant others.

  20. LMI Fuzzy Observer Design for Cryptography in Wireless Mobile Communications

    Directory of Open Access Journals (Sweden)

    2013-07-01

    Full Text Available Recently the engineering community began to seek the possibly application of chaos. The fact that the cryptographic community had used discrete pseudo-chaotic systems for a long time to generate cipher keys that leads to the initiation of applying chaos to secure communications. This paper presents a schematic design methodology for a fuzzy observer based secure communication of hyper chaotic systems in cryptographic applications. The transmitter and receiver, which are based on a 3D hyper chaotic oscillator, are synchronized by exploiting the concept on the observer from the control theory. The scalar transmitted signal is designed so that the hyper chaotic carrier masks the encrypted signal, which in turn hides the message signal. To encrypt the message signal, an n-shirt cipher with multiple key algorithms is proposed. In receiver side, the fuzzy observer of chaotic system is designed based on the general Takagi-Sugeno fuzzy model. This approach leads to the design of communication systems with higher security.

  1. Differential-Drive Mobile Robot Control Design based-on Linear Feedback Control Law

    Nurmaini, Siti; Dewi, Kemala; Tutuko, Bambang

    2017-04-01

    This paper deals with the problem of how to control differential driven mobile robot with simple control law. When mobile robot moves from one position to another to achieve a position destination, it always produce some errors. Therefore, a mobile robot requires a certain control law to drive the robot’s movement to the position destination with a smallest possible error. In this paper, in order to reduce position error, a linear feedback control is proposed with pole placement approach to regulate the polynoms desired. The presented work leads to an improved understanding of differential-drive mobile robot (DDMR)-based kinematics equation, which will assist to design of suitable controllers for DDMR movement. The result show by using the linier feedback control method with pole placement approach the position error is reduced and fast convergence is achieved.

    Considerable overlap exists between post-occupancy research evaluating building design quality and the concept of 'social value', popularised by its recent application to issues of the public realm. To outline this potential research agenda, the paper reviews design quality research on buildings in relation to users and their social context where the term 'social context' refers to building user group dynamics, a combination of organisational cultures, management strategies, and social norms and practices. The review is conducted across five key building types, namely housing, workplaces, healthcare, education, and the retail/service sector. Research commonalities and gaps are identified in order to build a more comprehensive picture of the design quality literature and its handling of users in their social context. The key findings concerning each building type are presented visually. It is concluded that the design quality field comprises a patchwork of relatively isolated studies of various building types, with significant potential for theoretical and empirical development through interdisciplinary collaboration. Users tend to be conceived as anonymous and autonomous individuals with little analysis of user identity or interaction. Further, the contextual impact of user group dynamics on the relationship between building design and building user is rarely addressed in the literature. Producing a more nuanced understanding of users in situ is proposed as an important area for future design quality research.

  10. Design Methodology for Self-organized Mobile Networks Based

    Directory of Open Access Journals (Sweden)

    John Petearson Anzola

    2016-06-01

    Full Text Available The methodology proposed in this article enables a systematic design of routing algorithms based on schemes of biclustering, which allows you to respond with timely techniques, clustering heuristics proposed by a researcher, and a focused approach to routing in the choice of clusterhead nodes. This process uses heuristics aimed at improving the different costs in communication surface groups called biclusters. This methodology globally enables a variety of techniques and heuristics of clustering that have been addressed in routing algorithms, but we have not explored all possible alternatives and their different assessments. Therefore, the methodology oriented design research of routing algorithms based on biclustering schemes will allow new concepts of evolutionary routing along with the ability to adapt the topological changes that occur in self-organized data networks.

    Full Text Available Diet was known for many years to play a key role as a risk factor for chronic diseases especially for elderly. The capability to interact effectively on health information application among elderly is becoming essential. A mobile technology can monitor diet and lifestyle of the elderly. We developed Nutrihealth application that comprises information on Body Mass Index (BMI, suggested menus, and calories intake. Persuasive techniques were implemented in the design of Nutrihealth mobile apps, to increase user engagement and behaviour change in healthy diet. The work starts with an initial study to select suitable persuasive techniques for elderly. The aim of this work is to evaluate the mobile application that implements a persuasive design. A technology acceptance model named Unified Theory of Acceptance and Use of Technology (UTAUT has been used in the evaluation phase. Nine (9 elderly participants take part in the in-depth usage study in which they were asked to use the mobile apps for 3-days. The findings show majority of participants (90% gave positive opinion on the design of the persuasive mobile apps. There is also an improvement in their calories intake during the 3-days study.

  18. Cross-Layer Design Approach for Power Control in Mobile Ad Hoc Networks

    Directory of Open Access Journals (Sweden)

    A. Sarfaraz Ahmed

    2015-03-01

    Full Text Available In mobile ad hoc networks, communication among mobile nodes occurs through wireless medium The design of ad hoc network protocol, generally based on a traditional “layered approach”, has been found ineffective to deal with receiving signal strength (RSS-related problems, affecting the physical layer, the network layer and transport layer. This paper proposes a design approach, deviating from the traditional network design, toward enhancing the cross-layer interaction among different layers, namely physical, MAC and network. The Cross-Layer design approach for Power control (CLPC would help to enhance the transmission power by averaging the RSS values and to find an effective route between the source and the destination. This cross-layer design approach was tested by simulation (NS2 simulator and its performance over AODV was found to be better.

  20. iShadow: Design of a Wearable, Real-Time Mobile Gaze Tracker.

    Continuous, real-time tracking of eye gaze is valuable in a variety of scenarios including hands-free interaction with the physical world, detection of unsafe behaviors, leveraging visual context for advertising, life logging, and others. While eye tracking is commonly used in clinical trials and user studies, it has not bridged the gap to everyday consumer use. The challenge is that a real-time eye tracker is a power-hungry and computation-intensive device which requires continuous sensing of the eye using an imager running at many tens of frames per second, and continuous processing of the image stream using sophisticated gaze estimation algorithms. Our key contribution is the design of an eye tracker that dramatically reduces the sensing and computation needs for eye tracking, thereby achieving orders of magnitude reductions in power consumption and form-factor. The key idea is that eye images are extremely redundant, therefore we can estimate gaze by using a small subset of carefully chosen pixels per frame. We instantiate this idea in a prototype hardware platform equipped with a low-power image sensor that provides random access to pixel values, a low-power ARM Cortex M3 microcontroller, and a bluetooth radio to communicate with a mobile phone. The sparse pixel-based gaze estimation algorithm is a multi-layer neural network learned using a state-of-the-art sparsity-inducing regularization function that minimizes the gaze prediction error while simultaneously minimizing the number of pixels used. Our results show that we can operate at roughly 70mW of power, while continuously estimating eye gaze at the rate of 30 Hz with errors of roughly 3 degrees.
