This paper conducts co-word analysis and social network analysis to review the research of relationship between usability of information system and user emotions. The results show that more and more studies focus on the topic which involves three perspectives, namely products design and evaluation, human-computer interaction design and evaluation, interface design and evaluation. The main issues include...
Second Life is a novel internet-based virtual environment and a large number of participants are attracted since it was founded. Meanwhile, various educational and social activities were carried out with many agencies involved in. According to the visual campus circumstance, a three-dimensional situational networked learning environment training rooms was established, and the key issues on how to...
Study status on shearer mining in thin seams in the world is introduced. Base on the geological conditions of instable and soft thin-seam with hard roof in Caoyao Coal Mine of Yima Coal Group, China, and combined with related parameters of strata behaviors at coal faces, the paper concludes that the strata control on the thin-seam coal face is comparatively easy in line with the criteria for classification...
This paper applies the cointegration theory to examine the long-run equilibrium relationship between China's power consumption and real GDP, electricity retail price, economic structure from 1978 to 2006. Our estimation results indicate that the real GDP, electricity sale price, economic structure are co- integrated and the long-run, income elasticity is 0.85,the long-run electricity price elasticity...
Pneumatic clutch system of heavy truck is nonlinear and its state parameters are variable. The common PID controller is difficult to obtain good performance. Neural network is adopted to tune the PID parameter online. The output of neural network is used to adjust the PID controller parameter and the controller adjusts the pulse width to control the displacement of the clutch. The experimental result...
