Application of strip electrode in single-gap RPC

The Resistive Plate Chamber (RPC) is widely used in High Energy Physics experiments as trigger detector to take advantage of its good time resolution and high efficiency. A conventional RPC detector consists of one gas gap covered by graphite layers on both side. The working voltage is applied on these layers and the charge of avalanche dissipates through them. In this paper, a design which removes the graphite layers and uses the readout strips as the electrode is applied to simplify the structure of this detector. This design eliminates the challenge of controlling the uniformity of the graphite layer and simplifies the detector structure.

Design of real-time actuated control system for modern tram at arterial intersections based on logic rules

This article is on the purpose of developing an isolated tram signal priority control strategy based on logic rule for modern tram system. The designed method is presented with features that can ensure the intersection operates in a proper manner on the premise of tram priority and avoid vehicle queue overflow when the tram passes. In this study, the new method description consists of two parts: (1) the detector locations are determined, which include the upstream detector, the upstream trigger detector, the downstream detector, and the queuing detector upon entry approach to the intersection; (2) the corresponding priority logical algorithm for signal control is designed. The proposed method is experimentally examined in a tram intersection in Huaian city, China. In the process of the experiment, the detector layout scheme and optimal priority control model are simulated and verified using the VisVAP module of the Vissim simulation software. In the experimental results, the designed scheme significantly decreases average delay than the fixed timing signal control method, while it also can prevent the vehicle queue from overflowing compared to the absolute priority actuated control scheme.
