A Current Mode, Parallel, Two-Rail Code Checker
IEEE Transactions on Computers, 2008 A current mode, periodic outputs, parallel two-rail code (TRC) checker, suitable for the implementation of high fan-in embedded checkers, is presented. The new checker is characterised by high testability, high speed operation and low silicon area requirements.

Electronics Letters, 2008 A new circuitry is introduced to maintain the constant signal behaviour for rail-to-rail input stages, and is suitable for general mixed-signal ultra-large-scale-integration and system-on-chip applications in contemporary nanoscale CMOS technologies. The constant signal performance is verified by experimental results in a 65 nm standard digital CMOS ...

An Ultrasonic Guided Wave Mode Excitation Method in Rails
IEEE Access, 2018 This paper proposes a new method for exciting a specific mode of guided ultrasonic wave in a rail. The method requires the cross-sectional mode shape to determine excitation direction, excitation coefficient, and excitation position of each mode. The cross-sectional mode shape data of all modes are acquired by the semi-analytical finite element (SAFE ...

High-Speed Rail as a New Mode of Intercity Passenger Transportation [PDF]
SSRN Electronic Journal, 2019 High-speed rail is a new mode of intercity passenger transportation. We review the history of high-speed rail development of the United States (US) and compare it with that of peer countries. With the rapid progress of HSR and the successful competition with cars and air travel between medium and long distances (150 and 1,200 km), HSR has an increasing

Mode boundaries of automated metro and semi-rapid rail in urban transit
Public Transport, 2021 Our research question is to what extent, and under what circumstances, full automation in metro lines defines transit mode boundaries with respect to semi-rapid transit. The modeling approach is based on micro-economic appraisal. Automation, beside changing the investment and operation and maintenance cost profiles of metro lines, can improve some ...

Current-Mode Rail-to Rail Instrumentation Amplifier for General Purpose Instrumentation Applications
International Journal of Applied Mathematics, Electronics and Computers, 2016 Instrumentation amplifiers are used extensively inbio-potential reading, industrial sensor applications, Wheatstone bridgeamplifiers etc. In this work, a high input common-mode range instrumentationamplifier is presented. The amplifier is composed of two second generationcurrent conveyors (CCII+) with common-mode input range close to supply swingsand ...

Constant gm, rail-to-rail input transconductance stage with output common mode current compensation
2006 13th IEEE International Conference on Electronics, Circuits and Systems, 2006 This paper presents a compensation structure to reduce the output common mode current of a rail-to-rail constant g m transconductance stage. The transconductance stage is a differential structure with the input transistors biased in weak inversion. This results in low power consumption and a simple relation between gm and tail currents.

Optimization of modes of plasma treatment crane rails
Technology audit and production reserves, 2015 Crane operation is accompanied with wear and tear of rails and crane wheels. Actual direction is the renovation and improvement of efficiency of these parts. Modern technologies of restoration of wheels and rails provide surface deposition or treatment with high-frequency currents.

Effect of Rail Support Mode on Wheel/Rail Dynamic Interaction of Metro Lines
Open Journal of Transportation Technologies, 2017 传统轨道结构中，钢轨铺设在均匀离散分布的轨枕上。钢轨支承方式不仅关系到轨道线路的建设造价，也对轨道车辆的运行安全与稳定有着重要的影响。本文基于车辆–轨道耦合动力学仿真，对钢轨连续及离散支承情形下地铁线路轮轨动力响应进行比较分析。计算结果表明，新型连续支承轨道结构上地铁车辆的轮轨力及钢轨的振动性能均优于传统的离散支承轨道。对于传统的钢轨离散支承地铁轨道，轨枕间距越小，车轮越过轨枕所引发的轮轨动态作用力和钢轨振动加速度越大。 Rails are discretely supported by uniformly distributed sleepers in traditional tracks.
