In this work, the finite-time control problem for sampled-data systems is investigated. The time-varying sampling is not required to be periodic, and the only assumption is that the distance between any two consecutive sampling instants does not exceed a given bound. First, the continuous-time systems with digital control are modeled as continuous-time systems with delayed control input. Then, a novel Lyapunov functional is used to solve the finite-time control problem. At last, sufficient conditions for the existence of state feedback finite-time controller are obtained by solving a set of linear matrix inequalities (LMIs). Different from many existing finite-time control designs of linear systems, this work extends the partial results to the sampled-data systems. The effectiveness of the proposed results is eventually illustrated by a numerical example. © 2014 Elsevier B.V.

Cr3+ doped transparent glass ceramics of SiO2-Ga2O3-Li2O were fabricated by melt-quenching and subsequent crystallization. X-ray diffraction and transmission electron microscopy analyses evidenced that cubic LiGa5O8 nanocrystals were homogeneously precipitated among the silicate glass matrix. The incorporation of Cr3+ ions into LiGa5O8 nanocrystals was evidenced by absorption, emission and time-resolved luminescence spectra. Impressively, the present Cr3+ doped glass ceramics were demonstrated to be a new near-infrared (~720nm) long-lasting bulk phosphor whose luminescence can last for more than 2h after stoppage of UV (250-350nm) irradiation. The occurring of Cr3+ long-lasting phosphorescence in the glass ceramics was confirmed to be mainly due to the precipitation of Cr3+:LiGa5O8 nanocrystals from glass matrix. The filling/releasing of electrons into/from the intrinsic traps of LiGa5O8 nanocrystals through the conduction band of host were proposed to be responsible for the realization of the long-lasting phosphorescence of the investigated Cr3+ doped glass ceramics. © 2014 Elsevier Ltd.

Purpose - The purpose of this paper is to investigate the impact of privacy concern on user adoption of location-based services (LBS). Design/methodology/ approach - Based on the data collected from a survey, structural equation modeling was employed to examine the research model. Findings - The results indicate that among four dimensions of privacy concern, collection and secondary use are the main factors affecting perceived risk, whereas errors are the main factor affecting trust. Trust affects perceived risk, and both factors determine usage intention. Practical implications - Mobile service providers need to alleviate users' privacy concern and perceived risk in order to encourage their adoption and usage of LBS. Originality/value - Extant research has mainly examined LBS user behavior from the perspectives of technology acceptance model, task technology fit and unified theory of acceptance and usage of technology. The results provided in this paper indicate that privacy concern also has a significant effect on user adoption of LBS. This advances our understanding of LBS user behavior. © Emerald Group Publishing Limited.

Due to the high perceived risk, building users' initial trust is crucial to facilitating their adoption and usage of mobile banking. Drawing on the elaboration likelihood model (ELM), this research examined users' initial trust in mobile banking. The results indicated that initial trust develops along a dual route including the central route and peripheral route. Self-efficacy as the elaboration likelihood moderates the effects of central cues and peripheral cues on initial trust. Central cues include information quality and service quality, whereas peripheral cues include system quality, structural assurance and reputation. The results imply that service providers need to employ differentiated strategies to build users' initial trust in mobile banking. © 2012 Elsevier Ltd. All rights reserved.

The inverted pendulum problem is one of the most important problems in control theory and has been studied excessively in control literatures. When a control system have more than two PID controllers, the adjustment of PID parameters is not an easy problem. In this paper, PID controllers are applied to the stabilization and tracking control of three types of inverted pendulum. The way how to design the PID controllers is given step by step in this paper. Simulation results prove that the way to design of PID controllers is very simple and effective. The system design not only can realize stabilization and tracking control of three types of inverted pendulum, but also have robustness to outer large and fast disturbances. © 2010 Elsevier B.V.

Retaining users and facilitating their continuance usage are crucial for mobile payment service providers. Drawing on the information systems success model and flow theory, this research identified the factors affecting continuance intention of mobile payment. We conducted data analysis with structural equation modeling. The results indicated that service quality is the main factor affecting trust, whereas system quality is the main factor affecting satisfaction. Information quality and service quality affect flow. Trust, flow and satisfaction determine continuance intention of mobile payment. The results imply that service providers need to offer quality system, information and services in order to facilitate users' continuance usage of mobile payment. © 2012 Elsevier B.V.
