Mobile learning systems (m-learning), even with benefits in terms of education, presents challenges that need to be explored, such as the lack of a specific educational modeling. The work presents the definition of a set of characteristics and requirements for educational modeling directed to the context of mobile learning, assisting and flexibilizing the creation of educational content. A systematic...
Enterprises have recognised the importance of personal mobile devices for business and official use. Employees and consumers have been freely accessing resources and services from their principal organisation and partners' businesses on their mobile devices, to improve the efficiency and productivity of their businesses. This mobile computing-based business model has one major challenge, that of ascertaining...
Keeping pace with the market requires software to be shipped quickly, in rapid release cycles with a strong feedback loop. Managing and controlling these changes become complex, especially in the mobile world. In mobile applications, unlike in the Web world, the user chooses whether to download updates or to ignore them, and rollbacks are typically not an option. This paper describes a centralized...
Television viewing is changing with a growing trend towards online consumption of content and a proliferation of providers. This is now starting to bring into question the future of the traditional television channel as the program itself becomes more dominant. However, this, in turn, poses a problem for the viewer in that it will become increasingly difficult to locate those programs of interest...
High-end graphics processing units (GPUs), such as NVIDIA Fermi/Tesla series cards, are widely applied to the high performance computing fields in a decade. NVIDIA releases Tegra K1, called Jetson TK1, which contains 4 ARM Cortex-A15 CPUs and 192 CUDA cores (Kepler GPU) is an embedded board with low cost, low power consumption, and high applicability advantages for several specific applications. In...
Online marketplaces are e-commerce websites where thousands of products are provided by multiple third parties. There are dozens of these differently structured marketplaces that need to be visited by the end users to reach their targets. This searching process consumes a lot of time and effort; moreover it negatively affects the user experience. In this paper, extensive analysis and evaluation of...
This paper presents the implementation of a Service Oriented Mobile AR Architecture focused on museum learning activities. The service-orientated architecture presented is a collaboration between a mobile AR platform and a web service framework that consumes third party service APIs or linked open data from participating museum collections. The architecture and associated codebase is used to implement...
Publish/Subscribe is known as a scalable and efficient data dissemination mechanism. In a mobile environment, there is an added challenge for the pub/sub system to economizemobile bandwidth, which is especially precious in areas not wellcovered by mobile providers. While well-known compressionmethods such as GZip or Deflate are generally useful in suchsituations, we propose using Shared Dictionary...
In this paper, we investigate the publish/subscribe standard WS-Notiflcation with respect to deployment and use in the tactical domain. We leverage a network emulator, CORE, to generate a testbed for controlled and repeatable experiments exhibiting typical tactical network traits: Limited data rates, delays, and packet loss, as well as node mobility and subsequent sporadic loss of connectivity. The...
Over the last 15 years the world as seen a surge in users owning smartphones and electronic devices. People today have smartphones that have the computational capabilities of computers from more than 45 years ago. With the growing populous under this information age, individuals have access to so much data. It is a fantastic time to spread ideas as anyone can reach anybody else over the internet almost...
In recent times size of the data is increasing rapidly. Existing centralized system is not able to handle large dataset beyond a certain limit. So, we need ontology based approach in Semantic Web and distributed system. Ontology describes a formal specification of certain domain. Existing platform and servers are unable to process different types of data like structured, semi-structured and quasi-structured...
In the today's advancing world of technology, Mobile Applications are rapidly growing segment of global mobile market. Mobile applications are developing at a meteor space to give user a rich and fast user experience. This paper involves an application for the android base operating system for an institute which will provide the detail and accurate information about an institute. This application...
This paper presents a novel approach based on structure recurrence in XML documents for Android mobile devices. The model identifies recurrent structures and gives a feasible solution to be easily adapted for resource constrained mobile devices. XML files with sequentially repetitive blocks of structures can be processed differently to reduce the processing time. It relieves the parser from the computationally...
Classified advertisements are moving to push their services to the mobile application due to a wide base of users. The potential challenge for this type of service in the data exchange model due to the enormous amount of information transferred to the mobile client in an asynchronous fashion. In this paper two data exchange methods are compared; XML and JSON. JSON outperforms in term of data size...
Mobility management is an essential feature of cellular networks. High accuracy of mobile user positioning is needed to handle mobility efficiently enough and bad cell data can harm this feature significantly. Inaccuracy of cell shapes, lack of cell data measurements, and inaccurate coordination in a geographical area are major shortcomings when it comes to positioning of mobile users in cellular...
Daily management of neurodegenerative diseases by electrical neuromodulation techniques requires an integrated health care system for the continuous assistance to the patient. In this scenario, a direct bi-directional exchange of information between the patient's electronic health record (EHR) and patient's personal mobile health apps (mHealth) can boost the active contribution of patients and caregivers...
We propose an open source robotic 3D mapping framework based on Robot Operating System, Point Cloud Library and Cloud Compare software extended by functionality of importing and exporting datasets. The added value is an integrated solution for robotic 3D mapping and new publicly available datasets (accurate 3D maps with geodetic precision) for evaluation purpose Datasets were gathered by mobile robot...
Multi-layer cloud network is a new paradigm of mobile cloud computing. In multi-layer cloud networks, any device could augment its resources by offloading their tasks to public clouds, private clouds, or even user devices. However, it is difficult to handle access control on data stored in different clouds which may offer various access control mechanisms. In this paper, the cloud access control (CAC)...
Web APIs provide a systematic and extensible approach for application-to-application interaction. A large number of mobile applications makes use of web APIs to integrate services into apps. Each Web API's evolution pace is determined by their respective developer and mobile application developers are forced to accompany the API providers in their software evolution tasks. In this paper we investigate...
Mobile carriers are struggling to cope with the surge in smartphone traffic, which reflects badly on end users who often experience poor connectivity in densely populated urban environments. Data transfers between mobile client applications and their Internet backend services contribute significantly to the contention in radio access networks (RANs). Client applications, however, typically transfer...
