Radio-over-fiber (RoF) technology is a comparatively mature technology which can effectively improve the reliability and quality of service (QoS) in railway communication systems. As a coverage strategy of RoF in long heavy haul railway tunnels (more than 1 km), directional antenna radiating same direction is highly valued. Due to the handover mechanism changed, handover trigger probability and outage...
Statistical time-to-failure analysis is a very powerful and versatile analytical tool available to reliability engineers and statisticians for understanding and communicating the failure risk and reliability of a component, device, or system. The typical approach to characterizing time to failure involves fitting a parametric distribution, such as a Weibull probability function, using time series...
Statistical time-to-failure analysis is a very powerful and versatile tool available to reliability engineers and statisticians for understanding and characterizing the failure risk and reliability of a component, device or system. Commonly applied methods of modeling time-to-failure involve fitting a parametric distribution, such as the Weibull probability function, using serial data on production...
