The FTRA Journal of Convergence covers the breadth of research in convergence technology and its applications. Theoretical research contributions presenting new techniques, concepts, or analyses, reports on experiences and experiments of implementation and application of theories, and tutorials on new technologies and trends are all welcome. Papers should emphasize original results relating to the theory and/or applications from a variety of convergence technologies. The subjects covered by the journal include all topics related to a) Computing and Communications; b) Security and Trust; c) Web and Multimedia; d) IT Managements and Services; e) Consumer Electronics.
The first issue of JoC Section A starts with an article by Yuko Muto, Kozo Okano and Shinji Kusumoto. The article entitled A Visualization Technique for Unit Testing and Static Checking with Caller-Callee Relationships, discusses a new hybrid method based on both categories: visualization of software component relationships and visualization of software metrics. The proposed method visualizes the coincidence between specification and implementation from static checking and ordinal testing by test suites. Through implementing the proposed method, the authors evaluate the utility of the proposed approach.
The article of Section B entitled Considerations on Security and Trust Measurement for Virtualized Environmenta by Xiaolin Wang, Yan Sang, Yi Liu, and Yingwei Luo analyze the security problem in virtualized environments and present their security evaluation criteria. Based on the evaluation criteria, they introduce new approach supporting technology and authentication method. The article entitled Towards on Open Framework for Mobile Digital Identity Management through Strong Authentication Methods by Brahim En-Nasry and Mohamed Dafir Ech-Cherif El Kettani propose an extensible protocol based on an independent architectural model that provides a foundation for user-centric identity management. In order to support extensible architecture, the authors choose a middleware-based approach, playing the role of a point of entry to online services and support the piloting of the identification process. The article entitled An Enhanced Middleware for Collaborative Privacy in IPTV Recommender Services by Ahmed M. Elmisery and Dmitri Botvich introduce a framework for private recommender service based on Enhanced Middleware for Collaborative Privacy executing a two-stage concealment process that gives the user a complete control on the privacy level of his profile. Trust mechanism is used to augment recommendation’s accuracy and privacy.
The article of Section C entitled Modeling the Impact of the Position of Frame Loss on Transmitted Video Quality by Ahmad Vakili and Jean-Charles Gregoire demonstrate that the interval between the lost frame and the last I-frame does have a significant effect on quality of transmitted compressed video using the average Peak Signal to Noise Ratio. Using this observation and further investigation, the authors propose a method for improving the performance of video streaming over noisy channels based on packet scheduling, without an increase in the bit rate. The article entitled Preheating Simulation of Power Battery by Maode Li, Feng Want, and Duying Wang simulate a power battery with rising temperature under the cases of forced convections. Through the observations, the authors explain the properties of rising temperature in the preheating process of the battery under different air velocities and temperatures.
We believe that these six articles have the good quality and relevance that we expect for developing JoC. Finally, we would like to thank all authors, reviewers, and members of the editorial board of JoC.
