Emerging large-scale distributed storage systems such as content delivery networks (CDNs) are faced with the task of distributing peta-bytes of requested data from mobile service users. In this paper, we present a novel cache architecture with enhanced performance that aims to reduce the data distribution load on CDNs for large-scale storage systems. Our proposed architecture is located between a...
Use of public transportation is on a rise, enabling greener cities and improvement of the quality of life of the city residents. The challenge for the public transportation system is that its demands are non linear and the passengers' experience depends on many human factors. UnCrowdTPG is a mobile service and a research platform that has been developed for understanding the mobility patterns of the...
Knowledge is power. In today's Information age, education is the de facto tool which enables thinking by transforming information into knowledge. It is valued to such an extent that the right to education is considered to be one of the fundamental rights of the people. However education is often disparaged. According to the United Nations, India is home to a staggering 287 million illiterate adults...
We describe our analysis of three months worth of collected human-physical environment interactions (foursquare check-in) data for two European cities: a medium-sized city in the Mediterranean and a larger city in North West Europe. Our analysis shows that though the data generated by the citizens is scarce (i.e. on average less than 15 users checked in at any time during the day), nevertheless they...
In this study, a long term mobile learning program was conducted and a survey was developed to explore the effects of mobile learning on five 21st century core competences, that is, collaboration, communication, complex problem-solving, critical thinking and creativity, using a sample of 606 high school students from 10 high schools in Taiwan. Exploratory factor analysis was conducted to show that...
With the rapid progress of mobile technologies and the popularity of wireless networks, educational settings and strategies have changed significantly. Learning environments are no longer limited to classrooms, instead, the importance of conducting learning activities for knowledge construction through interaction with physical environments has been emphasized. In the meantime, researchers have indicated...
In dense mobile wireless sensor networks, it is desirable to reduce traffic for data gathering as much as possible while satisfying an application requirement. In this paper, focusing on an application which monitors the time-variant shape of events, we discuss an approach to achieve an efficient monitoring with small traffic in dense mobile wireless sensor networks.
For security of Android operating systems, permission-based solutions are one of popular approaches but still exposed to two problems. First, there is coarse-grained relationship between a permission and its associated methods. Second, mobile users do not have rights to control the permissions of their applications. To solve these problems, we propose MacDroid that enables users to control the system...
While many virtual educational environments are already in use, few attempt to mix the virtual and the real worlds to a very high extent. The benefits of such approach could be groundbreaking, leading to new paradigms of education, however the complexity of the challenges and the scale of the effort are still very high. The "3D UPB" platform takes this approach of a fully mixed reality environment...
With the advancement of information technology, the wireless network and mobile device continue development, which make people can acquire new knowledge with unlimited time and space. Moreover, learners could interact with people or things in real time to truly experience the learning content and situation. Therefore, learning was no longer limited to classroom and time frame. As long as learners...
In this paper, we propose a new architecture for LTE/EPC network by leveraging the Openflow technology. We focus on making detail procedures for initial attach and default bearer setup in Openflow-enabled LTE/EPC network. By numerical analysis, we show the reduction of the signaling load of this procedure in our architecture compared to that in the traditional LTE/EPC architecture.
This paper proposes an efficient network mobility support scheme with direct home network prefix (HNP) assignment to reduce the location update cost and packet tunneling cost. Since the HNP of a Mobile Network Node (MNN) is directly assigned by the moving mobile access gateway (mMAG), instead of the local mobility anchor (LMA), using a sub-prefix of the mMAG's HNP, the proposed scheme minimizes both...
The practical training is one of the key measures of quality technical vocational training of skilled personnel. The paper studies the training base construction method, explores new ideas and communications technology professionals in vocational training through a school-enterprise cooperation, which forms a new type engineering practice center and communications technology professional development...
We present the results of the third phase in a three part study developing an application to reduce obesity levels in adolescents with a mobile fitness application that encourages youth to engage in fitness activity by providing social networking tools to facilitate motivation. In the first phase, we studied effecting positive attitudinal changes towards fitness. The second phase studied physical...
The paper summarizes success stories of Finnish and Russian research organizations that joined forces towards development of leading-edge ICT competences and their use in multidisciplinary applications. The partner organizations from both countries have developed close collaboration framework, which enabled them to implement three crossborder cooperation projects co-funded by the Karelia ENPI CBC...
MyHeart is a telehealth system designed to bridge the current gap in the Congestive Heart Failure care continuum that occurs when the patient transitions from the hospital to the home environment. The system uses wireless health devices and a mobile application on the patient's end, a rule-based expert system, and a dashboard on the clinician's end to facilitate the exchange of information pertaining...
The competition between enterprises in our country becomes fiercer in recent years, however, the rise of mobile Internet technology brings new opportunities for enterprise information management. Information management can help reduce the cost, enable recombination of technological process, improve the employee quality, promotes the innovation level, and enhance the competitiveness of enterprises...
A mobile video game designed to encourage physical activity in children in an organized outdoor setting is presented. Game elements of narrative based treasure hunt game: Pirate Adventure are designed by a team of IT and Health professionals to encourage primary school aged children to engage in physical activity. The mobile phone platform uses several sensor technologies; accelerometers, camera and...
Geology is a fundamentally important natural science that explores resources such as minerals, water, fossil fuels and many others. Geology's field of knowledge also has social relevance in preventing natural disasters. Because of these features, geology is important not only as a science itself but in several other areas, such as engineering, biology, and oceanography. In this context of a natural...
Mobile learning represents exciting new frontiers in education and pedagogy. However, students graduating with mobile computing based degree could potentially have less flexibility to work in different areas of the organization. In recent years fostering entrepreneurship has become a topic of highest priority in collegiate education. In fact, entrepreneurship education has been intensified in universities...
