This paper presents a case study of the impacts of 25kV traction power system on railway signalling system using copper cables as communication links. Several forms of interferences including electromagnetic including and conductive have been investigated and remedial measures implemented, with satisfactory results. Key-Words : Traction Power System, electromagnetic interference, railway signal...

We analyze Niels Bohr's proposed two-slit interference experiment with highly charged particles which argues that the consistency of elementary quantum mechanics requires that the electromagnetic field must be quantized. In the experiment a particle's path through the slits is determined by measuring the Coulomb field that it produces at large distances; under these conditions the interference ...

Most problems with the electromagnetic environment of medical institutions have been related to radiated electromagnetic fields and have been constructed from reports about electromagnetic interference (EMI) with electronic medical equipment by the radio waves emitted from mobile telephone handsets. However, radiated electromagnetic fields are just one of the elements. For example, little atten...

The positional and rotational accuracy of a direct-current magnetic tracking device commonly used in biomechanical investigations was evaluated. The effect of different metals was also studied to determine the possibility of interference induced by experimental test fixtures or orthopaedic implants within the working field. Positional and rotational data were evaluated for accuracy and resoluti...

Quasi-delay-insensitive (QDI) circuits are those whose correct operation does not depend on the delays of operators or wires, except for certain wires that form isochronic forks. In this paper we show that quasi-delay-insensitivity, stability and non-interference, and strong connuence are equivalent properties of a computation. In particular, this shows that QDI computations are deterministic. ...

Pacemaker technology has advanced rapidly over the last decade. A lot of everyday interference can be regarded as transient. The media tend to cover stories of relatively insignificant transient interference incurred by pacemaker wearers while many manuals gloss over the high risks, some potentially life-threatening. These include the reliability of pacemakers and the use of monopolar diathermy...

The electromagnetic compatibility (EMC) community, usually concerned with noise and interference at the electronic-system level, has recently focused more attention on integrated circuits (ICs). This review concentrates upon the recent advances in microelectronics technology, the understanding of internal couplings within ICs, parasitic emission, and susceptibility to radiofrequency interferenc...
