M-learning has emerged due to advancement in development of mobile technology, and takes place in language learning by utilizing the portability and wide use of mobile phone. Researches on m-learning were conducted to serve the best way to adopt language learning via mobile phone thus Iban language has been chosen to be implemented as a mobile dialogue-based application to promote language learning...
In the lab, partial discharge diagnosis has widely replaced the traditional RIV measurements. Additionally, partial discharge acceptance levels are being reduced due to the increasing use of composite material and a growing awareness of partial discharge phenomenon and their consequences. Adequate filtering of the supply voltage for induced voltage testing and the use of sensitive acoustic measurement...
For a ubiquitous systems to be widely used, interactions between ubiquitous services and users became critical. Complexity of contents provided to users through ubiquitous service is suggested as the core problem of interactivity. The main objective of this study is to propose an assessment metric for evaluating the usability of u-services. To assess the concept of interactivity with an empirical...
Through analysis the China Mobile Multimedia Broadcasting(CMMB) system and traditional multi-service's track and detection of China mobile multimedia broadcasting system, design a more efficient CMMB multi-service's track and detection method. In this way, we can realize track and detection of multiple services at the same time, reduce the share of system and the time of track, greatly improve the...
Operating systems of modern mobile devices, like e.g. iOS and Android, require the applications to conform to a life cycle model, to ensure the functional correctness of the application and its data integrity over exceptional behavior as e.g. out-swapping of the application. The applications life cycle events are triggered asynchronously by the system and depend on the environment. In order to test...
In this paper, we present our efforts related to the implementation of the prototype that utilizes gesture based interaction for supporting collaborative explorations of visualizations in technology-enhanced learning activities. The prototype enables the visualization of different types of geo-tagged content and sensor data collected using mobile devices. In order to test the novelty and interactivity...
Vocabulary learning is a critical task for language learning. Recently years, many studies exerted efforts to mobile English vocabulary learning, however, little work has been conducted to discuss the usage of VLSs (vocabulary learning strategies) on contextualized or ubiquitous learning. In this study, the researcher proposes a personalized VLS framework and applied it on mobile English vocabulary...
This survey paper describes and classifies solutions/approaches that use Mobile Agents in Wireless Sensor Networks. There are eight identified criteria which are used for classification of available solutions/approaches and include: autonomicity, security, adaptability, availability, routing, filtering, recovery, and configuration. For each criterion, a selected solution/approach is described so that...
Machine learning is a theory that enhances a computer system's knowledge. Besides, support vector machine (SVM) is a machine learning theory with neural networks. That is, the SVM has two major functions; namely, classification and regression analysis for application. To enhance the intelligence of system's tool, mobile wavelet SVM is applied to the proposed tool system on personal digital assistant...
In the conventional framework for failure diagnosis of partially observed discrete event systems, it is assumed that, for each event, the corresponding output symbol is determined uniquely. However, this assumption does not hold in discrete event systems such as a mobile system, where an output symbol depends on not only an event but also a state at which the event occurs. In this technical note,...
Implementation of mobile application should be tested on the mobile platform. Since there are several mobile platforms compete in the marketplace, a lot of effort is needed to test the implementations on every platform. This research aims to develop an integrated test automation framework by which implementations on multiple heterogeneous platforms can be tested efficiently. Commonly used events in...
The need for faster and more different ways of communication had led to the great increase in number of mobile terminals. A great number of software applications has been developed and also measurement equipment and testing procedures. Increased need for packet data transfer contributed to GSM system evolution to GPRS, and later to EDGE. In this paper, we will demonstrate procedures and results of...
Location based on fingerprinting comprises two distinct phases: the first phase, off-line phase, is related with two tasks, a site survey to collect data for the Fingerprint Map (FM), and its generation based on the collected data; the second phase, on-line phase, is related with the location of a mobile terminal, by doing the comparison of the data acquired from the wireless transceiver with the...
Dealing with customer support issues can often affect Agile teams negatively. It can impact both their focus on new features and their predictability. This paper shows how Fundamo made use of a Kanban system to take control of their customer support issues and drive quality improvements in their Agile development process.
In Ilmenau, Germany, a new laboratory is under construction for testing mobile communication equipment, both satellite and terrestrial. This contribution focuses on Over-The-Air testing of terrestrial mobile terminals and on applications of Wave Field Synthesis in this laboratory. The terrestrial research in the lab will mainly serve scientific purposes, as research into OTA test methodologies, also...
In this paper, an over-the-air test strategy for evaluating cognitive radio nodes is presented. This technique allows to emulate the activities of primary and secondary users with respect to received power spectral densities, and the spatial structures of their radio channels. This enables an experimental evaluation of cognitive devices with directional and spectral sensitivity. This type of testing...
This document proposes an architecture to produce software for use by U.S. soldiers on commercially available smart phones and other mobile hardware to increase their productivity. The architecture decreases time to production while maintaining Department of Defense Information Assurance standards.
The packet-switched NGN (Next Generation Network) architecture allows users to access multimedia services via the Internet anytime and anywhere. Through the core IP Multimedia Subsystem (IMS), NGN can provide multimedia services, such as voice, video, data and messages over heterogeneous networks. However, for high-quality services in practical environment, the performance and QoS (Quality of Service)...
Modeling mobile users' behavior can lead to crucial applications in accountable mobile computing such as casual authentication and anomaly detection. We introduced a language approach to model mobile users' behavior from heterogeneous sensor data. By converting temporal and spacial features generated from WiFi RSS trace into symbols and fusing them into a 1-dimension ``language'' representation, we...
