Some of the main trends in modern Homeric scholarship have been, in the 19th and early 20th centuries, Analysis and Unitarianism ( see Homeric Question ), schools of thought which emphasized on the one hand the inconsistencies in, and on the other the artistic unity of, Homer ; and in the 20th century and later Oral Theory, the study of the mechanisms and effects of oral transmission, and Neoanalysis, the study of the relationship between Homer and other early epic material.

Some commentators have likened the transmission of memes to the spread of contagions.

Some manufacturers created systems that allowed their own equipment to interconnect, but each scheme used a different transmission rate, so one manufacturer's systems could not synchronize with those of another.

Some proprietary applications, such as phantom-powered footswitch controllers, use the spare pins for direct current ( DC ) power transmission.

Some pulse modulation schemes also allow the narrowband analog signal to be transferred as a digital signal ( i. e. as a quantized discrete-time signal ) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example some line code.

Some sources prefer the term safer sex to more precisely reflect the fact that these practices reduce, but do not completely eliminate, the risk of disease transmission.

Some articles published before 1977 used the term signal transmission or sensory transduction for signal transduction: a total of 48, 377 scientific papers related to signal transduction were published in 1977, of which 11, 211 were reviews of other papers.

Some jurisdictions, such as Minnesota, prohibit energy transmission companies from selling surplus communication bandwidth or acting as a telecommunications common carrier.

Some regulators regard electric transmission to be a natural monopoly and there are moves in many countries to separately regulate transmission ( see electricity market ).

Some HVDC power transmission systems use the ground as second conductor.

Some modern optical power meters have the capability to set to zero the reference level measured at the output of the reference fiber, so that the transmission loss of the fiber under test may be read out directly.

Some of the power that is fed into a transmission line is lost because of its resistance.

Some parasites modify host behavior to make transmission to other hosts more likely.

Some transmission systems contain multipliers, which amplify a signal prior to re-transmission, or regenerators, which attempt to reconstruct and re-shape the coded message before re-transmission.

Some of the original designs for the power transmission plants were created by the Swiss firm Faesch & Piccard, which also constructed the original 5, 000 HP waterwheels.

Some of the high voltage transmission lines carrying power through the laboratory's land are built to echo the Greek letter π.

Some skylights have expensive glazing that partially reduces summer solar heat gain, while still allowing some visible light transmission.

Some plastics also have more advantageous optical properties than glass, such as better transmission of visible light and greater absorption of ultraviolet light.

Some very low-cost home computers or embedded systems dispensed with a UART and used the CPU to sample the state of an input port or directly manipulate an output port for data transmission.

Some new reservoirs for hydroelectric schemes have been given names faithful to the names for natural bodies of water-for example: the Loch Sloy scheme, and Lochs Laggan and Treig ( which form part of the Lochaber hydroelectric scheme near Fort William ).

Some rhyming schemes have become associated with a specific language, culture or period, while other rhyming schemes have achieved use across languages, cultures or time periods.

Some forms of poetry carry a consistent and well-defined rhyming scheme, such as the chant royal or the rubaiyat, while other poetic forms have variable rhyme schemes.

Some types of more complicated rhyming schemes have developed names of their own, separate from the " a-b-c " convention, such as the ottava rima and terza rima.

Some piano makers developed schemes to enhance the tone of each note.

Some piano makers developed schemes to enhance the tone of each note.

Some encryption schemes can be proven secure on the basis of the presumed difficulty of a mathematical problem, such as factoring the product of two large primes or computing discrete logarithms.

Some schemes are based on the discretion of an official, such as a social worker.

Some of his schemes, while not resulting in an escape, do lead to the dismissal of an incumbent Number Two on two occasions.

Some schemes that require authentication allow a username, and perhaps a password too, to be embedded in the URL, for example < tt >< nowiki > ftp :// asmith @ ftp. example. org </ nowiki ></ tt >.

Some schemes have " rules " agreed to by the players but not enforced by the game itself.

* Bit order: Some schemes view the low-order bit of each byte as " first ", which then during polynomial division means " leftmost ", which is contrary to our customary understanding of " low-order ".

Some of these are get-rich-quick schemes, though many others affect the financial security of the Duke farm, which Hogg has long wanted to acquire for nefarious reasons.

Some would travel from state to state peddling schemes of administrative or military reform.

Some countries have ruled that matrix schemes are illegal on that basis.

The network marketing or multi-level marketing ( abbreviated MLM ) business has become associated with pyramid schemes as " Some schemes may purport to sell a product, but they often simply use the product to hide their pyramid structure.

Some are pyramid schemes.

Some believe MLMs in general are nothing more than legalized pyramid schemes.

Some inkjet manufacturers have tried to prevent cartridges being refilled using various schemes including fitting smart chips to the cartridges that can detect when the cartridge has run out of ink and prevent the operation of a refilled cartridge.

Some progress was also made increasing the pay of NHS manual workers through incentive schemes.

Some signaling schemes do not use electrical wires.
