This article is concerned with the output feedback exponential stabilization for a flexible beam with tip mass. When there is no disturbance, it is shown that only one noncollocated measurement is enough to exponentially stabilize the original system by constructing an infinite-dimensional Luenberger state observer to track the state and designing an estimated state-based output feedback control law. This essentially improves the existing result in (Conrad et al. 1998) where two collocated measurements, including high-order feedback were adopted. In the case that boundary internal uncertainty and external disturbance are considered, an infinite-dimensional disturbance estimator is constructed to estimate the state and total disturbance in real time. By virtue of the estimated state and estimated total disturbance, an output feedback control law is designed to exponentially stabilize the original system while guaranteeing the boundedness of the closed-loop system. Some illustration simulations are presented.

On the one hand, as the basic work forms, team is paid more and more attention. Team is a important view of research. At same time, studies find that emotional intelligence is not only a tool in management, but also is antecedent variables. But, on the other hand, according to the previous study, the researches on relation between emotional intelligence and performances are limited in individual level, and don’t make a deep study to the mechanism between them. Based on the two points, this paper chooses team members as object of study, and researches the mechanism from individual level and team level. These results open the black box that emotion intelligence effects performance. At same time, these results provide a good research perspective and bases for follow-up research and in human resource management practices.

The negative actions of the customers and staff-the customer's interactional injustice and CPB are important in corporation. Through Questionnaire survey about 420 employees, this paper researches the relationship among the CPB, NA and customers interactional injustice. These research results not only provide a powerful support for the pressure source-mood theories, but also give a good view and basis of the research for follow-up study. At the same time, they are also an important reference value for enterprise management practices.

In this paper we define and develop a theory of the Riemann-Liouville fractional semigroups and show that they are equivalent to the fractional resolvents of [K. Li, J. Peng, Applied Mathematics Letters, 25 (2012), 808–812].

Emotional intelligence is an important issue which has been concerned by the Psychologies and foreign business management in recent years. Emotional intelligence is a capability, is one kind of potential to create profit. But, as we know, capability itself doesnt create values directly, creating values needs to act. So it is important to research on what the relationship between emotional intelligence and performance is. This paper adds citizenship behavior variable as modulation in order to find the mechanism that EI influences performance. Through empirical research, we find that citizenship behavior is mediator between EI and performance. This solution is important value to propel management theory and to guide concrete practice.

For further development and building a solid foundation of industrial Internet of things, a wireless communication card (WCC) based on UWB used in industrial Internet of Things (IoT) is designed in the paper. The implementations of WCC are proposed and critical problem on software design is solved. It successfully solves the problem of communication with IO card. At the same time, it provides upgrade program form industrial control systems to industrial Internet of Things.
