One significant way in which the duplication issue has remained important emerged from the introduction of another factor. By the time of St. Mâlo and the first U.S. formal response to it, the NATO Alliance was also “seized of” concerns about its own military resources and capacities. Having successfully completed the design phase of adapting the NATO Alliance to meet the challenges of the post...

abstract. the main purpose of this paper is investigation and identification the concept of dynamic capabilities and clarifying the relationship between these capabilities with the knowledge management process capabilities. as expected, the results showed a positive relationship between these two concepts. this paper includes three main sections. in first section, we identify the concept of pro...

Transcoding is an important technique for reducing the bit rate or spatial resolution to meet the constrained transmission bandwidths and terminal capabilities. In this paper, we propose a spatial downscaling transcoding method to convert an MPEG-2 bitstream into an H.264/AVC bitstream. A novel feature of the proposed method is to focus on the fast mode decision that fully exploits the advantag...

Traditional transcoding on multimedia has been performed from the perspectives of user terminal capabilities such as display sizes and decoding processing power, and network resources such as available network bandwidth and quality of services (QoS) etc. The adaptation (or transcoding) of multimedia contents to given such constraints has been made by frame dropping and resizing of audiovisual, ...

Multimedia is gaining ever more importance on the Internet. This increases the need for intelligent and efficient video caches. A promising approach to improve caching efficiency is to adapt videos. With the availability of MPEG-4 it is possible to develop a standard compliant proxy cache that allows fast and efficient adaptation. We propose a modular design for an adaptive MPEG-4 video proxy t...

according to the resource based attitude, the capabilities of information systems improve firms’ performance and competitive advantages through three ways: 1) inside-outside capabilities, 2) outside-inside capabilities and 3) spanning capabilities. because of the importance of systematic study on the relationship between these capabilities and firms’ performance this paper was aimed at investig...

The computer world is experiencing a paradigm shift towards context-aware pervasive computing, where diverse computer devices communicate with each other through different network access technologies, and allow resource access based on user preferences. P2P computing is an area which will be affected by this new trend. In this paper, we proposed a resource replication strategy for context-aware...

Beyond 3G usually refers to heterogeneous scenarios where different Radio Access Technologies (RATs) coexist and operate in a coordinated way. This brings a new challenge to offer services to the users over an efficient and ubiquitous radio access. In this way, the user can be served through the RAT that fits better to the terminal capabilities and service requirements, and also a more efficien...

The future of mobile telecommunications is aimed at creating a usercentric wireless world which takes into account user’s preferences, as well as communication context (e.g., network and terminal heterogeneity or user location). In order to enable context-aware personalization of communication services offered by next-generation mobile networks, we propose an agentbased approach in combination ...
