Some modern editing systems can use OCR techniques to read BITC in situations where other forms of timecode are not available.

Some linguists, such as John DeFrancis and J. Marshall Unger have argued that genuine ideographic writing systems with the same capacities as natural languages do not exist.

Some writing systems of the world, notably the Arabic and Hebrew scripts, and derived systems such as the Urdu, Persian, Yiddish, Jawi, and Ladino scripts, are written in a form known as right-to-left ( RTL ), in which writing begins at the right-hand side of a page and concludes at the left-hand side.

Some systems used both codes and ciphers in one system, using superencipherment to increase the security.

Some take the approach of looking for coherent justifications of established copyright systems, while others start with general ethical theories, such as utilitarianism and try to analyse policy through that lens.

Some critics of this approach feel that while these models approach biological reality as a representation of how the system works, they lack explanatory powers because complicated systems of connections with even simple rules are extremely complex and often less interpretable than the system they model.

Some jurisdictions give priority to motorized traffic, for example setting up one-way street systems, free-right turns, high capacity roundabouts, and slip roads.

Some masters use different systems, or even no system at all.

Some light rail systems may run on a narrower gauge.

Some missiles can be fitted with any of a variety of navigation systems ( Inertial navigation, TERCOM, or satellite navigation ).

Some GC systems allow such other resources to be associated with a region of memory that, when collected, causes the other resource to be reclaimed ; this is called finalization.

Some, like VirtualBox and VMware Player run on Windows and Linux hosts and can run many other operating systems.

Some predictions had been made concerning factors R, N, I and Co on these inventories which appeared to be directly related to control and security aspects of personality functioning which were hypothesized as being of importance in differential Kohnstamm reactivity.

Some of those who did not initially react with an arm-elevation also associated their behavior in the situation with control factors -- an inability to relinquish control voluntarily.

Some drug treatments that have been used to control ataxia include: 5-hydroxytryptophan ( 5-HTP ), idebenone, amantadine, physostigmine, L-carnitine or derivatives, trimethoprim – sulfamethoxazole, vigabatrin, phosphatidylcholine, acetazolamide, 4-aminopyridine, buspirone, and a combination of coenzyme Q10 and vitamin E.

Some of the minor effects include changes to the airflow that lead to problems in control.

Some basic types of responsiveness such as reflexes can be mediated by the spinal cord or peripheral ganglia, but sophisticated purposeful control of behavior based on complex sensory input requires the information-integrating capabilities of a centralized brain.

* Some curves that seem simple, such as the circle, cannot be described exactly by a Bézier or piecewise Bézier curve ; though a four-piece cubic Bézier curve can approximate a circle ( see Bézier spline ), with a maximum radial error of less than one part in a thousand, when each inner control point ( or offline point ) is the distance horizontally or vertically from an outer control point on a unit circle.

Some of the more technical safety measures include that all new Croatian tunnels have modern safety equipment and there are several control centers, which monitor highway traffic.

Some computers were built using " writable microcode " — rather than storing the microcode in ROM or hard-wired logic, the microcode was stored in a RAM called a writable control store or WCS.

Some programs have gradually integrated real-time controllers and gesturing ( for example, MIDI-driven software synthesis and parameter control ).

Some measures of vector control include:

Some content-control software includes time control functions that empowers parents to set the amount of time that child may spend accessing the Internet or playing games or other computer activities.

Some ISPs offer parental control options.

Some of the mods give server administrators more flexible and efficient control over his or her server.

Some programming languages have a related control structure, the short-circuit or, written ||, or else, etc.

Some players use the more nimble tips of the fingers to play fast-moving solo passages or to pluck lightly for quiet tunes. The use of amplification allows the player to have more control over the tone of the instrument, because amplifiers have equalization controls that allow the bassist to accentuate certain frequencies ( often the bass frequencies ) while de-accentuating some frequencies ( often the high frequencies, so that there is less finger noise ).

Some libertarians in the U. S. object to vouchers on the grounds that granting government money, even indirectly, to private and religious schools will inevitably lead to increased governmental control over non-government education, and possibly over the teachings of the sponsoring religious group ( most often a church ).

Some musicians who use rackmounted effects or laptops employ a MIDI controller pedalboard or armband remote controls to trigger sound samples, switch between different effects or control effect settings.

Some aircraft, the Panavia Tornado for example, retain a very basic hydro-mechanical backup system for limited flight control capability on losing electrical power, in the case of the Tornado this allows rudimentary control of the stabilators only for pitch and roll axis movements.

Some studies published in peer-reviewed journals have shown that it is very difficult for young children to control their curiosity even when they have been taught not to touch firearms.

Some horses, particularly stallions, may have a chain attached to the lead rope and placed over the nose or under the jaw to increase the control provided by a halter while being led.

Some related styles of headgear that control a horse with a noseband rather than a bit are known as bitless bridles.

Some restrictions preclude the South African market from following international trends, the local is restricted to local investment opportunities in terms of exchange control, the lack of regulated structures restricts the amount of exposure which the South African retirement fund industry has to hedge fund strategies and foreign investors are put off investing directly into South African hedge funds by adverse taxes and other obstacles.
