Single-Phase Alternating-Current Railway Work

Alternating Current Electrospraying

Electrospraying has attracted the attention of many researchers, ranging from analytical chemists to physicists, not only because of the rich physics associated with it, but also due to its wide-ranging applicability. Therefore, considerable research has been devoted to exploring this interfacial phenomenon. However, there still are areas of electrospraying that have remained unexplored. Until ...

Alternating Current Theory -

1 November 2001 Alternating Current Theory J R Lucas An alternating waveform is a periodic waveform which alternate between positive and negative values. Unlike direct waveforms, they cannot be characterised by one magnitude as their amplitude is continuously varying from instant to instant. Thus various forms of magnitudes are defined for such waveforms. The advantage of the alternating wavefo...

Single-Phase Resistive Superconductor Electrical Current Limiter

This paper presents the analysis, design, construction and ac test results of low voltage single-phase resistive superconductor electrical current limiters. Two different types of resistive superconductor current limiter are presented: the first one is built with three concentric, cylindrical and helicoidal coils connected in parallel and the second one is built with two superposed cylindrical ...

Phase Synchronization in Railway Timetables

Timetable construction belongs to the most important optimization problems in public transport. Finding optimal or near-optimal timetables under the subsidiary conditions of minimizing travel times and other criteria is a targeted contribution to the functioning of public transport. In addition to efficiency (given, e.g., by minimal average travel times), a significant feature of a timetable is...
