Modern manufacturing systems are human robot systems that consist of human operators and intelligent robots collaborating with each other to accomplish complex tasks. The system performance of such human robot systems relies heavily on reliable and efficient human robot collaborations, which may be seriously compromised due to temporal variations in human to robot trust. This paper proposes to model...
This study has examined the technological innovation capability (TIC) and the patterns of investment into technology introduction and internal process to find the dynamic change of the investment patterns with capability growth of Chinese power equipment manufactories based on 71 samples from 5 provinces. We observe the change of openness, closeness and PvP (the ratio of input in platform innovation...
We investigate the maximum outage throughput for Orthogonal Frequency Division Multiple Access (OFDMA) systems in the presence of feedback channel capacity constraints. We attempt to establish an information-theoretic lower bound on the capacity of feedback channel and build the corresponding test channel that achieves this lower bound. Based on the derived test channel, we formulate the outage throughput...
Based on previous researches on Technology Innovation Capability (TIC), this paper has redefined TIC as a firm's technology acquisition and application capability both internally and externally under innovation strategy based on capital investment. The Open Innovation (OI) Theory emphasizes the significance of external technology and resources, which has made a breakthrough of traditional Close Innovation...
This study has examined the connection of activities in innovation related resource management and the profit status due to technological innovation based on a sample 219 firms in Chinese power equipment manufacturing industry. We have taken correlation and regression analysis to test the impact of different activities on 3 types of innovation. The result has provided us with the key activities which...
We propose a resource allocation algorithm for OFDM system to provide QoS guarantee for unicast and multicast service concurrently. The optimization objective is to maximize the sum rate of the unicast service under the constraint of both the total power and the minimal rate provision of the multicast service, which can be solved by traditional two-step approach. To decrease the complexity, a greedy-based...
In this paper, we propose a predictive resource allocation algorithm for multicast downlink OFDM systems with imperfect channel state information (CSI). We assume that the CSI is fed back to the base station (BS) through a delayed channel. To avoid the system degradation caused by the outdated CSI, we present a channel prediction scheme at the user side, which takes the delay time into account. Then,...
