Unlike the concentrated winding, not every tooth pole is wound in a distributed winding; instead, coils are in slots and span multiple pole teeth. Since the winding may block slots from further insertion of wire, it may be necessary to wind a complete phase winding at one time. Comparison of concentrated and distributed windings
In power engineering, winding factor provides a way to compare of the effectiveness of different designs of stators for alternators. Winding factor is the ratio of electromotive force (EMF) produced by a stator having a short-pitch, distributed, or skewed winding, with a stator having full-pitch, concentrated, and non-skewed, windings.
The Gough Map, dating to about 1360, is the oldest known road map of Great Britain. In 1500, Erhard Etzlaub produced the "Rom-Weg" (Way to Rome) Map, the first known road map of medieval Central Europe. It was produced to help religious pilgrims reach Rome for the occasion of the "Holy Year 1500".
The term Distributed GIS was coined by Bruce Gittings at the University of Edinburgh.He was responsible for one of the first Internet-based distributed GIS.In 1994, he designed and implemented the World Wide Earthquake Locator, which provided maps of recent earthquake occurrences to a location-independent user, which used the Xerox PARC Map Viewer (based in California, USA), managed by an ...
A strip map is a road map laid out similarly to a straight-line diagram, featuring the same details found in more conventional road maps rather than technical details. In the United States, some strip maps are distributed by state highway departments. [2] In Australia, strip maps are distributed by state automobile associations.
Since the 1960s, railroad distributed power technology has been dominated by one company, Harris Controls (originally Harris Corporation — Controls & Composition Division, later purchased by General Electric—the division now known as GE Transportation) who have manufactured and marketed a patented radio-control system with the trade-name of Locotrol, which is the predominant wireless DP ...

1838 map of pre-railroad cargo traffic in Ireland, one of the first thematic maps to use proportional symbols. The earliest known map to visually represent the volume of flow were two maps by engineer Henry Drury Harness, published in 1838 as part of a report on the potential for railroad construction in Ireland, showing the quantity of cargo traffic by road and canal.
