The period saw the growth of a distinct and trained architectural profession; before the mid-century "the high-sounding title, 'architect' was adopted by anyone who could get away with it". But most buildings were still designed by builders and landlords together, and the wide spread of Georgian architecture, and the Georgian styles of design more generally, came from dissemination through pattern books and inexpensive suites of engravings. This contrasted with earlier styles, which were primarily disseminated among craftsmen through the direct experience of the apprenticeship system. Authors such as the prolific William Halfpenny (active 17231755) received editions in America as well as Britain. From the mid-18th century, Georgian styles were assimilated into an architectural vernacular that became part and parcel of the training of every architect, designer, builder, carpenter, mason and plasterer, from Edinburgh to Maryland.

How did most Georgian design styles disseminate?
Answer: pattern books and inexpensive suites of engravings

Modern electrification systems take AC energy from a power grid which is delivered to a locomotive and converted to a DC voltage to be used by traction motors. These motors may either be DC motors which directly use the DC or they may be 3-phase AC motors which require further conversion of the DC to 3-phase AC (using power electronics). Thus both systems are faced with the same task: converting and transporting high-voltage AC from the power grid to low-voltage DC in the locomotive. Where should this conversion take place and at what voltage and current (AC or DC) should the power flow to the locomotive? And how does all this relate to energy-efficiency? Both the transmission and conversion of electric energy involve losses: ohmic losses in wires and power electronics, magnetic field losses in transformers and smoothing reactors (inductors). Power conversion for a DC system takes place mainly in a railway substation where large, heavy, and more efficient hardware can be used as compared to an AC system where conversion takes place aboard the locomotive where space is limited and losses are significantly higher. Also, the energy used to blow air to cool transformers, power electronics (including rectifiers), and other conversion hardware must be accounted for.

What type of losses happen during conversion and transmission in wires and electronics?
Answer:
ohmic losses
