Previous research on the social impact of communication technologies has followed two distinct directions and has considered independently either the interpersonal communication or the mass communication. In this context, the human–computer interaction aspects of integrated media and social communication are examined. The design of “Social TV” systems that support interpersonal communication, w...

In this study, we employ a numerical model to compare the performance of a number of wave energy converter (WEC) control strategies. Each control strategy was evaluated on a single numerical model using sea states to represent a deployment site of the coast of Newport, OR. A number of metrics, ranging from power-flow characteristics to kinematics are employed to provide a comparison of each con...

trum f ¨ ur K ¨ unstliche Intelligenz, DFKI) with sites in Kaiserslautern and Saarbrücken is a non-profit organization which was founded in 1988. The shareholder com-The DFKI conducts application-oriented basic research in the field of artificial intelligence and other related subfields of computer science. The overall goal is to construct systems with technical knowledge and common sense which...

Camera-captured document images usually contain two main types of marginal noise: textual noise (coming from neighboring pages) and non-textual noise (resulting from the page surrounding and/or binarization process). These types of marginal noise degrade the performance of the preprocessing (dewarping) of camera-captured document images and subsequent document digitization/recognition processes...

Traditionally, plantation sector in India has been regarded as a source of foreign exchange. Hence the system of innovation and production evolved over the years mainly at the instance of the state has been geared to enhance its international competitiveness. Though the role of plantation sector in the export basket of India declined over the years, the paper argues that the present role of pla...

Mobile offloading is a promising technique to aid the constrained resources of a mobile device. By offloading a computational task, a device can save energy and increase the performance of the mobile applications. Unfortunately, in existing offloading systems, the opportunistic moments to offload a task are often sporadic and short-lived. We overcome this problem by proposing a social-aware hyb...

Most research on 3D user interfaces aims at providing only a single sensory modality. One challenge is to integrate several sensory modalities into a seamless system while preserving each modality’s immersion and performance factors. This paper concerns manipulation tasks and proposes a visuo-haptic system integrating immersive visualization, tactile force and tactile feedback with colocation. ...

Recent developments in data mining and machine learning approaches have brought lots of excitement in providing solutions for challenging tasks (e.g., computer vision). However, many approaches have limited interpretability, so their success and failure modes are difficult to understand and their scientific robustness is difficult to evaluate. Thus, there is an urgent need for better understand...

We study the correlation complexity (or equivalently, the communication complexity) of generating a bipartite quantum state ρ. When ρ is a pure state, we completely characterize the complexity for approximately generating ρ by a corresponding approximate rank, closing a gap left in Ambainis, Schulman, Ta-Shma, Vazirani and Wigderson (SIAM Journal on Computing, 32(6):1570-1585, 2003). When ρ is ...
