The study results reported here are part of a larger research project that developed a manual for practitioners to improve safety at rail transit platform/train and platform/guideway interfaces. As part of that effort, passenger injury incident data was collected from five rail transit systems, and interviews were conducted with safety officers at other rail transit systems in the US and Canada...

Dual-rail encoding, return-to-spacer protocol and hazard-free logic can be used to resist power analysis attacks by making energy consumed per clock cycle independent of processed data. Standard dual-rail logic uses a protocol with a single spacer, e.g. all-zeroes, which gives rise to energy balancing problems. We address these problems by incorporating two spacers; the spacers alternate betwee...

The evaluation of trial operation of urban rail transit is a decisive link of whether the new line of urban rail transit can put into trial operation. Whether the result of evaluation is objective, reasonable and effective has a direct relation with whether urban rail transit can ensure operation safety and satisfy the basic service requirements. Therefore, it is very important to make sure tha...

Railway transport is a type of transport which is commonly used today. Rail line must be robust due to the heavy structure of the railway vehicles. Components constituting the rail line are very important to prevent the disruption of transportation. In this study, faults are determined by monitoring the rail and fastening components constituting the railway. Test vehicle was used to get experim...

This project presents a high-throughput and ultralowpower asynchronous domino logic pipeline design method, targeting to latch-free and extremely fine-grain or gate-level design. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical data path, the handshake circuits ...

A novel design method of asynchronous domino logic pipeline, which focuses on improving the circuit efficiency and making asynchronous domino logic pipeline design more practical for a wide range of applications. The data paths are composed of a mixture of dual-rail and single-rail domino gates. Dual-rail domino gates are limited to construct a stable critical data path. Based on this critical ...

Investigation of vertical vibrations of a railway turnout is important in designing track components under moving loads of trains. In this paper, the turnout is simulated by a linear finite element model with modal damping. A section of the turnout has a length of 36 sleeper spans surrounding the crossing. Rails and sleepers are modeled with uniform Rayleigh- Timoshenko beam elements. The rail...

The purpose of this study was to investigate whether the gating of interlimb cutaneous reflexes is altered by holding an earth-referenced handrail during locomotion. In the first experiment, subjects performed locomotor tasks of varying difficulty (level walking, incline walking, and stair climbing) while lightly holding an earth-referenced rail. In the second experiment, the extent of rail con...

The leakage resistance of rail to earth is an important parameter of electrified railways, and it directly affects the characteristics of traction return current and railway signal track circuit. High speed railways mainly adopt the ballastless track in China, whose rail leakage resistance is very different compared to the resistance in the ordinary railway ballast track condition, usually has ...

An ultra low-power high-speed rail-to-rail buffer amplifier with improved current summing circuit is proposed for LCD source drivers. By placing two complementary differential pairs in parallel, it is possible to obtain a rail-to-rail input stage. Then, a current summing circuit with two embedded comparators is proposed. With the proposed current summing circuit, the output stages will be turne...
