This is in contrast to earlier crossbar systems where the original switch train was simply built up and expanded as the call was connected, and not dropped in favor of a completely new one. It also uses entirely the same four-stage switching fabric for incoming as for outgoing calls, instead of separate fabric, as had been done in earlier systems.
Other times, people simply built on top of older structures. Technology, including lidar and radar, helps uncover some lost or abandoned cities. Warming temperatures and drier conditions have ...
More than 156,000 prefabricated homes were built between 1945 and 1948. [18] Prefabs were also built in World War I, such as the still-occupied houses in Austin Village, Birmingham. Despite the intention that these dwellings would be a temporary measure, many remained inhabited many decades after the end of World War II.

Growing up in Nordrach, where, for example, replacement parts for his gramophone were not readily available, he simply built the parts himself. As of 2018, the Junker Group has filed over 80 patents, including groundbreaking technology for the grinding industry.

Ankh-Morpork is built on black loam, broadly, but it is mostly built on itself; pragmatic citizens simply built on top of the existing buildings rather than excavate them out as the river flooded and the sediment grew too high. There are many unknown basements, including an entire "cave network" below Ankh-Morpork made up of old streets and ...
A structure as simply built as a high hoop tunnel, but much longer in length and on a slope, can permanently generate an airflow for producing electricity. Changing the chimney's height differential from 200 m (the Manzanares experiment) to 2000 m (Charleston Peak in Nevada has a rise of over 2500 m, for example) will transfer a factor of ten ...
