Force saturation, System Bandwidth, information transfer, and surface quality in haptic interfaces
Proceedings 2001 ICRA. IEEE International Conference on Robotics and Automation (Cat. No.01CH37164), 2001Co-Authors: R. Kilchenman, M. GoldfarbAbstract:This paper presents a two-part study of the effects of maximum endpoint force and System Bandwidth on haptic perception. First, size identification experiments were performed to determine the effects of System quality, in terms of these two System parameters, on the ability of a human to identify square cross-section ridges by size in a simulated environment. Then, discrimination experiments were performed to determine the relationships between haptic interface machine parameters and simulation quality in terms of perceived surface hardness. Results indicate that haptic interface hardware may be able to convey sufficient perceptual information to the user with relatively low levels of force feedback and System Bandwidth, yet subjects can perceive improvements in simulated surface quality as levels are further increased.

resource isolation in ran part while utilizing ordinary scheduling algorithm for network slicing
Vehicular Technology Conference, 2018Co-Authors: Daisuke Nojima, Takuya Shimojo, Yoshifumi Morihiro, Yuki Katsumata, Takahiro Asai, Akira Yamada, Shigeru IwashinaAbstract:In the context of resource isolation for network slicing, this paper introduces two resource allocation methods especially for the radio access network (RAN) part. Both methods can be implemented by slight modification of the ordinary packet scheduling algorithm such as the proportional fairness algorithm, and guarantee resource isolation by limiting the maximum number of resource blocks (RBs) allocated to each slice. Moreover, since both methods flexibly allocate RBs to entire System Bandwidth, there are cases in which throughput performance is improved compared to when the System Bandwidth is divided in a static manner, especially in a frequency selective channel environment. Numerical results show the superiority of those methods to simply dividing the System Bandwidth in a static manner, and show the difference between the features of the methods in terms of throughput performance of each slice.

Hybrid-mode embedded compression for H.264/AVC video coding System
2005 International Symposium on Intelligent Signal Processing and Communication Systems, 2020Co-Authors: Tung-chien Chen, Yu-han Chen, Ke-chung Wu, Liang-gee ChenAbstract:Applications of high resolution videos have great potential for H.264/AVC. However, due to the multi-frame motion estimation and large search range (SR) requirement, the ultra high System Bandwidth becomes the challenge for the plateform based video codec. In this paper, a hybrid-mode embedded compression (EC) is proposed. Two different strategies are respectively used to compress the reconstructed macroblocks (MBs) of intra- and intermode. Up-to 9.2 times of compression ratio (CR) can be achieved even with lossless-compression constraint. Besides, with resource sharing, this System can be integrated into H.264/AVC codec with almost no area overhead. According to the simulation results, the System Bandwidth can be reduced by 66.2% and 75.3% in average for high and median quality situation.

System Bandwidth Analysis of Multiview Video Coding with Precedence Constraint
2007 IEEE International Symposium on Circuits and Systems, 2007Co-Authors: Pei-kuei Tsung, Li-fu Ding, Wei-yin Chen, Shao-yi Chien, Tung-chien Chen, Liang-gee ChenAbstract:Multiview video coding (MVC) Systems require much more Bandwidth and computational complexity relative to mono-view video Systems. Thus, when designing a VLSI architecture for MVC Systems, the hardware resource allocation is a critical issue. In this paper, we propose a new System Bandwidth analysis scheme for various and complicated MVC structures. The precedence constraint in the graph theory is adopted for deriving the processing order of frames in a MVC System. In addition, current block centric scheduling (CBCS) and search window centric scheduling (SWCS) are proposed for MVC Bandwidth analysis. By adopting data reuse schemes, several design points are explored with the aid of the proposed analysis scheme. The suitable hardware resource allocation can be easily determined.
