O2O E-commerce is booming. The consumer trust is important to the development of O2O, so this paper studies the related factors of consumer trust degree of O2O in four dimensions, including customer factor, vendor factor, website platform factor and transaction environment factor. We set up a comprehensive evaluation method based on Analytical Hierarchy Process and the fuzzy analysis. Empirical analysis...
Electromagnetic properties of hydroxylapatite and oxalate powders are characterized over 1.7–2.6 GHz using a WR-430 rectangular waveguide. The effective dielectric constant and loss tangent of both compounds are derived from the measured S parameters. Effective medium theory is then applied to extract the intrinsic property of each compound. The extracted intrinsic dielectric constants are 3.37 and...
This paper addresses the problem of establishing hybrid instrument tracking using optical and electromagnetic devices for therapeutic application. Concretely, the hybrid tracking method is a video tracking system based on tracking a uniquely designed marker, and present a scenario where the electromagnetic system can be combined with the video based system to obtain a cost-effective system. A developed...
This paper proposes the terminal fuzzy sliding mode controller for the Duffing-Holmes system. A terminal sliding mode controller can drive the close-loop system to stable in finite time. In this paper, based on a rigorous mathematical analysis and Lyapunov stability theory, a terminal fuzzy sliding mode controller is designed that the controlled system state can be driven to zero state. The terminal...
