With recent advances in video encoding and network technology, media streaming services are getting popular. Media streaming system based on the traditional server/client or CDN architecture has a scalability problem, and peer-to-peer media streaming system using resources of peers in the system can provide better scalability. Previous media streaming services are suited to play stored contents such...
One of the most interesting and still not completely understood phenomena happening in Social Network Sites is their ability to spread (or not) units of information which may aggregate to form large distributed conversations. In this paper we present the result of an empirical study on a Large Social Database (LSD) aimed at measuring the factors enabling information spreading in Social Network Sites.
Recently, a huge wave of social media has generated significant impact in people's perceptions about technological domains. They are captured in several blogs/forums, where the themes relate to products of several companies. One of the companies can be interested to track them as resources for customer perceptions and detect user sentiments. The keyword-based approaches for identifying such themes...
Nanoimprint Lithography presents unique opportunities for high density patterning due to its advantages of sub-10nm resolution capability and high throughput. Imprint and pattern transfer with Pillar tone template were widely studies recently. However, there are several critical issues that still remain very challenging, including fabrication of pillar templates and pattern reverse from imprint holes...
Various media owns its living space for its specific dissemination feature and ecological niche with special time and space. This article uses media ecology theory to study the effect and function of digital television on the living environment of television media, with the purpose of analyzing the change for the whole media ecology environment. With the application of basic analysis for paradigm...
We propose the ontology-based inference rule for an experience media authoring system. The experience media lets people feel realistic while satisfying the five senses. The experience media means the media recreating more realistic situation by utilizing various peripheral devices in addition to audio-visual contents. The proposed ontology has advantages in producing the experience media by defining...
This paper designs and implements an automatic network system utilizing UPnP, wireless network and power line carrier technology. We connect home media device and home gateway device via wireless network to build media service subsystem, and connect home applications and home gateway via power line carrier network to make power control subsystem. Then we convert both subsystems into UPnP virtual devices,...
Using streaming media technology can effectively break the bandwidth bottleneck and make video/audio streaming over Internet smoothly. Based on the campus network facility and multimedia network classroom, this article use streaming media technology to form a network of teaching, analysis of the streaming media architecture, give a description of the system to connected and technical points, and make...
Introduces a prototype of wearable observation supporting system for helping human complete the observation and recognition tasks based on wearable camera. The research presented here addresses special challenge problems encountered in wearable computing environment. The implementation of new architecture and system process flow with functions will help the wearers real-time face detection, recognition...
This paper describes the prospects and challenges of cry preservation of tissue and tissue engineered products for their application to tissue repair and regeneration. The various aspects of cry preservation include optimization of cell specific freezing parameters such as cooling rate, type and concentration of cry oprotective agents (CPA), media, treatment methods, warming and thawing for the preservation...
Challenging the centuries, old statement cartilage do not regenerate, several, reports are describing, the presence of, condroprogenitor populations within ostheoarthritic cartilage., Osteophytes are non-osteoplastic protrusions, which, are formed gradually into an OA joint, into certain predictable, anatomical locations., Known to be related to evolution and progress of the disease, osteophytes formation...
We report a theoretical study and simulations of a novel fiber-spin tailoring technique to suppress the polarization impairments, namely polarization mode dispersion and polarization dependent gain (PDG), in fiber Raman amplifiers. Whereas use of depolarizer or multiplexing pump laser diodes with a final degree of pump polarization of 1% for periodically spun fiber results in PDG of about 0.3 dB,...
We describe the design and implementation of a secure and robust architectural data management model suitable for cultural environments. Usage and exploitation of the World Wide Web is a critical requirement for a series of administrative tasks such as collecting, managing and distributing valuable cultural and artistic information. This requirement introduces a great number of Internet threats for...
In this paper, we analyzes IPTV security threats via the the triple play. That is, the distribution system for IPTV service is analyzed along with the components of the value chain and corresponding IPTV security requirements or security technologies under the triple play, in order to perform a threat analysis and research suitable for the IPTV service environment.
Making the semantic description and automatic semantic annotation of the image which contains rich contents and intuitive expression is a research subject that is challenging. It is a key technology of realizing fast and effective image retrieval and a research focusing on cross media mining. Also it has great application value in various kinds of fields. This paper studies and discusses image media...
IPTV transfers network TV signals based on IP protocol. Monitoring the IPTV data transmission quality is of great importance to the extensive deployment and persistent improvement of IPTV services. RFC4445 proposes the metric of MDI (Media Delivery Index) in which DF (Delay Factor)and MLR (Media Loss Rate) are utilized to do quantitative evaluation to the transmission quality of IP video. However,...
A new genre of P2P systems, P2P Video-on-Demand (P2P-VoD), has not only received substantial recent research attention, but also been implemented and deployed with success in large-scale real-world streaming systems, such as PPLive. The essential characterization of P2P-VoD systems is to take full advantage of peer upload bandwidth contribution with a cache on each peer. Meanwhile, the asynchronous...
Media hashing is a compact representation of media content, one potential application of which is for content-based information retrieval. In the earlier work [13], the invariance of the spatial-domain histogram in shape to geometric deformations has been successfully exploited for image hashing. In this work, we extend the invariance into the discrete wavelet transform (DWT) domain to make this hashing...
The principle of Reusable Learning Objects(RLO) is to break education material into smaller chunks of material that can be readily digested and more easily learn by the learner. Hence, creating and developing courses based on RLO(s) gives learners the option to select courses that rebased on the learners personalised needs, optimised to cognitive needs and financially viable as well as creating courses...
In this paper, we propose a new system for enhanced viewing of electronic text. It is named ??Magnifying And Simplifying System for Text EXTension (MaSSTExt)??. This system for displaying text has the operational feeling like a map system displayed on a web browser. No link buttons are used for changing the other pages in this system because it is made by using Ajax. Then, it allows us to display...
