Estimation Method for Friction Coefficient between Wheel and Rail by a Single-Wheel Creep-Force Model Using Measurement Data of Instrumented Wheelset The purpose of this study is to improve estimation accuracy for motion variables of a wheelset in a railway vehicle calculated by an observer based ...
Elaine Cockroft, Project Manager at Network Rail stated: "The aim is to develop a first of type product addressing the issue of low adhesion on the wheel/rail interface and consider a tribometer/measurement tool capable of determining the co-efficiency of friction on the rail head. "The medium...
A UE can perform selection / reselection / handover operations to the HST LTE network cells with a higher priority based on various criteria, including a high mobility state of the UE, a marker, a cell ID, a measurement report comparison, or a location. Mobility state estimation of an ...
The New York State Index of Consumer Sentiment as of March stands at 68, down 5.1 points from the last measurement in the fourth quarter of 2021, according to the latest poll by the Siena College Research Institute (SCRI). New York’s overall Index of Consumer Sentiment is 8.6 points above...
Major items of measurement on the ground were rail deflections, rail stress, stress on fastening device, track vibration acceleration and sleeper stress. Major measured items on the car were wheel side thrust, wheel load, bogie stress, car body vibration, axle box vibration and similar forces....
“The conflicts which arise from shared train types on a twin-track railway will remain with us until we increase that track capacity. We are undertaking a study of the requirements to deliver a four-track section, and believe this critical infrastructure should be accelerated to enable cont...
The Bayesian optimization approach to traffic state estimation evaluates the posterior distribution of the system state given a prior state estimate and measurement data. The traffic state of the system xk at time k is defined as: (2)xk=[p1k,…,pik]Twhere pi is the traffic state in road ...
but imagine trying to measure how hard the surface of a jelly is by hitting it with a hammer. You’d get an idea of the jelly’s hardness by doing so, but after the act of “measurement” you wouldn’t be left with the same jelly. And before the measurement you wouldn’t be able...
With an 1-A output current capability in a 3-mm x 3-mm footprint, designers of highly-sensitive telecom, medical, radar and test and measurement applications can overcome noise and solution size challenges. Explore techniques for reducing internal noise for a clean supply rail that won't ...
