This paper presents a new approach for adapting a multimedia presentation into heterogeneous and dynamically changing environments. A novel media adaptation taxonomy is proposed that includes synchronized media optimization and scaling. The taxonomy incorporates multi-dimensional interaction between media, service requirements and presentation. Network properties, terminal types and integration...

User behavior in a website is a critical exponent of the web site’s usability. Therefore an understanding of usage patterns is essential to website design optimization. This challenging problem is prominent in media-rich websites, due both to the complexity of analyzing media-based content and the challenge of understanding user-media interactions. Towards this goal, we present a novel paradigm...

Community detection is an unsupervised learning task that discovers groups such that group members share more similarities or interact more frequently among themselves than with people outside groups. In social media, link information can reveal heterogeneous relationships of various strengths, but often can be noisy. Since different sources of data in social media can provide complementary inf...

In the past decade or so we have been experiencing an extraordinary explosion of data volumes first in wireline networks and recently even in mobile wireless networks. Optimizing bandwidth utilization is critical for planning and deploying efficient networks that are capable of delivering new services like IPTV over cost-oriented implementations. Models of distributed content caching in the acc...

In the paper presented here the optimization of Halbach arrays as storage media for mechanical potential energy is investigated with numerical simulations using FEMM and analytical calculations using the Maxwell stress tensor. Two opposing Halbach arrays form a “magnetic spring” and mechanical potential energy is stored when this structure is compressed. It is here seen that the wavelength of t...

/department of mechanical engineering Introduction Noise reduction is a key issue for High-tech and high precision instruments. To reduce the noise levels emitted by internal or external sources, porous materials can be used for acoustic shielding. The acoustic wave penetrates into the pore network, and part of its energy is dissipated as heat by viscous friction and thermal-elastic damping, ma...

OBJECTIVE To provide a systematic overview of the effects of various parameters on contrast enhancement within the same population, an animal experiment as well as a computer-aided simulation study was performed. MATERIALS AND METHODS In an animal experiment, single-level dynamic CT through the liver was performed at 5-second intervals just after the injection of contrast medium for 3 minutes...

Emotion detection can considerably enhance our understanding of users’ emotional states. Understanding users’ emotions especially in a real-time setting can be pivotal in improving user interactions and understanding their preferences. In this paper, we propose a constraint optimization framework to discover emotions from social media content of the users. Our framework employs several novel co...

Our primary focus is enabling and accelerating biological drug manufacture through the development of costeffective technologies that facilitate rapid bioprocess development and improve manufacturing “bang-for-thebuck”. Using data mining and cell-based screens we have designed the RegocelTM small molecule yield enhancers for a number of mammalian cell platforms used in biomanufacturing such as ...
