In this paper, discuss the upgrade system for an old type and extend to new line system of signaling at Taipei Rapid Transit Systems (RTS). Since the track circuits of fixed block are utilized the frequency loops and audio frequency track circuits of train position detected on the automatic train protect system. At present, Neihu line is the new extension construction of Muzha line, due to the ...

conclusion scout views may be useful in determining dose and image quality in ct scanning; however, it is necessary to first determine the most appropriate scout view for ct scans. background while using the automatic exposure control technique in computed tomography (ct), the scout view determines the radiation dose for the ct scan by taking anatomical morphology into consideration. objectives...

Abstract With the rapid development of economy and technology, people’s quality life has been continuously improved, which also makes people put forward higher requirements for transportation. As far as railway transportation is concerned, running speed route trains in past gradually failed to meet travel needs. Automatic train operation system (ATO), under protection automatic system, realizes...

Purpose: To consider the need for rational choice of values automatic control system (ACS) parameters by speed long freight train locomotive under condition ACS management necessary quality provision. Choosing method to solve task parametric synthesis and indicators. Finding rational, from view accepted assessment, trains various mass length. Methods: Methods mathematical simulation modeling, e...

”Open Proof (OP) is a new approach for safety and security critical systems and a further development of the Open Source Software (OSS) movement, not just applying OSS licensing concepts to the final software products itself, but also to the entire life cycle and all software components involved, including tools, documentation for specification, verification, implementation, maintenance and in ...

The introduction of the European global navigation satellite system GALILEO allows also for a modernization of automatic train control technology. This is advisable because of the still enormous amount of collisions between trains or other kinds of obstacles (construction vehicles, construction workers, pedestrians), even if comprehensive and complex technology is extensively deployed in the in...

The safety of train traffic is a vital societal function. During the mid-1970s, the availability of inexpensive microprocessors and electronic components led to the first computer-based systems solution to this critical function. Sweden was the first country in the world to develop and deploy a computer-based solution for Automatic Train Control (ATC). The major suppliers Ericsson Signal System...
