Throughout the last decade, there has been an alarming de- crease in daily physical activity among both children and adults. Medical experts agree that physical activity is crit- ical to maintaining fitness, reducing weight and improving health. Yet so many people have dificulty increasing and maintaining physical activity in everyday life. We have cre- ated a solution calledMove2Play, which encourages a health- ier lifestyle and motivates to participate in regular physical activity. We have integrated four essential parts that form the basis for long-term progress and sustainability - Activity Recommendation, Tracking, Evaluation and Motivation. In order to recognize and assess physical activity, we have developed a system for mobile phones that collects data from various sensors, such as accelerometer, GPS and GSM. We provide personalization, i.e. we have proposed and realized activity recommendation for an individual user to ensure that the users engage in regular exercise, as opposed to oc- casional outbursts of activity, which are unhealthy and even harmful. We discuss our proposed mechanisms of activity recommendation and the concept of motivation, which rep- resent a key element for any system that fights the sedentary lifestyle of the modern generation.

To some extent, contemporary software development has incorporated the AspectJ style of aspect-oriented programming. This style is denoted as asymmetric since it explicitly distinguishes between aspects and the base. Although academic symmetric aspect-oriented approaches, in which there is no such distinction, gained no direct acceptance in industry, several approaches used in practice exhibit symmetric aspect-oriented features. As shown in this paper, this ranges from peer use cases and features as analysis and design concepts to particular programming language mechanisms such as traits (Scala), open classes (Ruby), or prototypes (JavaScript). Even inter-type declarations and advices as known from AspectJ can be used to emulate symmetric aspect-oriented programming. The examples given in this paper indicate the basic possibilities for this. However, detailed studies of the corresponding academic and industry approaches should be carried. © 2012 ACM.

Finding an accurate network null model for protein-protein interactions (PPI) networks is an important and fundamental problem in today's systems biology. A number of graph models were introduced to model and analyze PPI networks. However, because the previous network models were developed to capture specific network properties or just mimic the way that real PPI network might have evolved, the whole connectivity information of PPI networks is not utilized to learn the topological structure of the networks. In this paper we propose a novel model for PPI networks which is based on geometric random graphs and employs the entire connectivity information of PPI networks to learn its structure. The computational experiments show the superiority of the fit of our method over five other network models to PPI data. Thus, the proposed network null model could facilitate further graph-based studies of protein-protein interactions and may help infer their hidden underlying biological knowledge. © 2012 Springer-Verlag.

OWL ontologies are used to represent knowledge in web. In recent years, with the wide application of Semantic Web, large numbers of OWL ontologies have appeared on Internet, especially, in some virtual knowledge communities. These ontologies are distributed in different sites and provide an amount of knowledge to query. But, it has become a pressing issue that, given a semantic query, how to efficiently gather the related knowledge from these ontologies located in different sites to process it. To address this issue, in this paper, we propose a P2P-based approach to publish axioms in sharable ontologies and freely sharing them in an open distributed environment. Given a query of SPARQL, this approach can automatically gather published axioms related to the query to process the query. As a knowledge sharing approach, our approach can directly share axioms coming from different ontologies on different nodes. It overcomes limitations of those approaches which focus on how to locate related ontologies for a query. We also conducted two experiments to evaluate the effectiveness and the efficiency of our approach. The experimental results demonstrated that it is effective and efficient. © 2012 Springer-Verlag Berlin Heidelberg.

Future applications for embedded systems demand chip with high performances such as computing, throughput and power consumption. Multiprocessor system-on-Chip (MPSoC) is a promising solution to meet the requirements. And embedded devices are designed to support more modern applications, but cost lower in design and products. The key design challenges are designing systems for multiple use-cases and fast exploration of software and hardware implements automatically. In this paper we present an automatical design and synthesis methodology to generate multiprocessor systems in a systemic way for multiple applications. And to support multiple use-cases, Techniques are presented to merge these use-cases onto a hardware architecture. And a desired multiprocessor design is generated with minimal resources cost and short design time, making it suited for fast design exploration in MPSoC systems. The proposed design flow is implemented into a tool DSMAMPS for Xilinx FPGAs. As a case study, the tool is used to carry out design exploration of some typical applications. The experiments results illuminate that our design methodology is a convenient approach to generate the MPSoC design for multiple use-cases.

Scheduling reputation maintenance in agent-based communities using game theory

Abstract-In agent-based systems, agents can be organized within groups, called communities, where members are providing similar or complementary services. Agentbased communities of web services is an example of such systems. Managing reputation of each agent and of the whole community is a key issue towards securing this type of systems, where a controller agent is designed to observe and check the behavior of each member to update and maintain the system's reputation. Scheduling the maintenance activity by deciding about the moment where the check has to be done is still an open problem. Because it is highly expensive, maintenance cannot be done every moment or based on small history of agents' behaviors. We propose in this paper a scheduling algorithm that helps the controller agent improve the quality of the reputation mechanism, which increases the trust value of users toward the community. The proposed algorithm is based on a class of games called Bayesian Stackelberg. Our Bayesian Stackelberg game is designed between the controller agent and community members, for example agent-based web services. We simulate and compare the efficiency of our algorithm with other stochastic techniques, namely uniform, normal and Poisson distributions. This research draws the lines for future work in the subject of optimizing reputation mechanisms through maintenance in different time intervals. © 2012 ACADEMY PUBLISHER.

Modern embedded devices need to support a large number of new coming applications. For users' satisfactions of potential use-cases, MPSoC system is one of the promising solutions. But it becomes a challenge to predict the performance and analyze the design, especially when applications may be dynamically scheduled in the system. This paper presents a probabilistic technique to predict the performance of multiple applications on MPSoC system. And probabilistic computing and analysis is used to estimate the time of tasks executions in the contention with resources, and thereby predicting the performance of applications. And we present an approach of finding well-performing designs, using computational models of evolutionary fuzzy system. It utilizes fuzzy decentralized computation grids to control decision and find well-performing policies for performance characteristics. The results of applications probability prediction are presented, and also compared results of simulation and FPGA implementation for multiple applications. © 2012 Binary information Press.

Thanks to fast development of mobile technologies, it is possible to use modern mobile phones for different purposes and in areas for which they weren't primarily intended. For example: entertainment, spreading information and so on. This paper deals with application for mobile technologies in process of learning in the form of so called mobile learning or mLearning. The basis for this form of education is the opportunity to learn anywhere and anytime. In this paper we analyse so far presented researches, projects and commercial applications in the field of education. The goal of our research was to design and implement application for smartphone, which will offer to students' advantages of modern mobile devices in the process of computer programming learning. One of the functions of this application is to plan the learning process, so the student would use his free time to study. We have analysed the possibility of using mobile devices in the context of existing education system. We have designed and implemented an application NoMEd for educational content synchronization. And we also achieved actual learning results by training on the selected mobile device.
