—In order to enhance multicast communication , it is important to investigate effects of network coding which can be a typical application of active network. In this paper, we study the feasibility of network coding based multicast architecture from performance aspect. We first show that the network coding based multicast has not only high transmission(More)
We investigate the use of compressive sampling for networked feedback control systems. The method proposed serves to compress the control vectors which are transmitted through rate-limited channels without much deterioration of control performance. The control vectors are obtained by an ℓ 1-ℓ 2 optimization, which can be solved very efficiently by FISTA(More)
SUMMARY In remote control, efficient compression or representation of control signals is essential to send them through rate-limited channels. For this purpose, we propose an approach of sparse control signal representation using the compressive sampling technique. The problem of obtaining sparse representation is formulated by cardinality-constrained 2(More)
SUMMARY This survey summarizes the state-of-the-art research on network coding, mainly focusing on its applications to computer networking. Network coding generalizes traditional store-and-forward routing techniques by allowing intermediate nodes in networks to encode several received packets into a single coded packet before forwarding. Network coding was(More)
Efficient text recognition has recently been a challenge for augmented reality systems. In this paper, we propose a system with the ability to provide translations to the user in real-time. We use eye gaze for more intuitive and efficient input for ubiquitous text reading and translation in head mounted displays (HMDs). The eyes can be used to indicate(More)
