* 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 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 people even wrote code to vibrate the head at different frequencies to play simple tunes.

Some of the works are simple abstracts of black ink on white paper, similar to a Rorschach test.

Some of these simple programs are based on fractal geometry, and can map midi notes to specific fractals, or fractal equations.

Some undergraduate courses require a team of 2 to 5 students to design, implement, and test a simple CPU in a FPGA in a single 15 week semester.

Some consider etiquette a simple negative ethics, i. e., where can one evade an uncomfortable truth without doing wrong?

Some relatively simple homeostatic mechanisms are generally accepted.

Some, such as Kompas and Koran Tempo are circulated around Indonesia daily and are relatively simple to obtain.

Some of IBM's engineers and other employees wanted to use the IBM 801 processor, some would prefer the new Motorola 68000, while others argued for a small and simple microprocessor, such as the MOS Technology 6502 or Zilog Z80, which had been used in earlier personal computers.

Some simple carbohydrates ( e. g. fructose ) follow different metabolic pathways ( e. g. fructolysis ) which result in only a partial catabolism to glucose, while many complex carbohydrates may be digested at essentially the same rate as simple carbohydrates.

Some mainstream academics also argue the Oxford theory is based on simple snobbishness: that anti-Stratfordians reject the idea that the son of a mere tradesman could write the plays and poems of Shakespeare.

Some pasta dishes are served as a first course in Italy because the portion sizes are small and simple.

Some of these microorganisms have receptors to simple sugars from the decomposition of chitin.

Some simple instructions:

Some of these RFCs would not be published at all today ; an early RFC was often just that: a simple request for comments, not intended to specify a protocol, administrative procedure, or anything else for which the RFC series is used today.

Some qualitative properties of quantum strings can be understood in a fairly simple fashion.

Some divers instead connect their backup regulator to a smaller " pony cylinder " for extra safety, and there are also emergency systems which mount a simple regulator directly to the top of a small cylinder.

Some versions have a simple scoring system: each block removed is worth one point, and there is no bonus for removing more than two blocks at a time.

Some simple examples of spinors in low dimensions arise from considering the even-graded subalgebras of the Clifford algebra.

Some salamanders that are terrestrial have lungs that are used in respiration, although these are simple and sac-like, unlike the more complex organs found in mammals.

Some text editors are small and simple, while others offer broad and complex functions.

Some, like Louis Jacobs, argue that the main body of the Gemara is not simple reportage of conversations, as it purports to be, but a highly elaborate structure contrived by the Saboraim, who must therefore be regarded as the real authors.

Some later V-2s used " guide beams ", radio signals transmitted from the ground, to keep the missile on course, but the first models used a simple analog computer that adjusted the azimuth for the rocket, and the flying distance was controlled by the timing of the engine cut-off, " Brennschluss ", ground controlled by a Doppler system or by different types of on-board integrating accelerometers.

Some protocols and specifications in the OSI stack remain in use in legacy systems.

Some cooling towers operate on this principle ; similarly the solar updraft tower is a proposed device to generate electricity based on the stack effect.

Some instructions give one or both operands implicitly, such as by being stored on top of the stack or in an implicit register.

Some players may choose to buy into games with a " short stack ", a stack of chips that is relatively small for the stakes being played, with the intention of going all in after the flop and not having to make any further decisions.

Some of this was unavoidable due to the path that the calls took through the Jet-based stack.

Some single-board computers also exist as form factors that stack like building blocks, and do not have the form of a traditional backplane.

Some older " non native " software was still in TNS stack machine form.

Some stacks last for a very long time-possibly because they don't get submerged easily ( for example the volcanic stack near Australia.

Some regularly replace their older corms with a stack of younger corms, increased more or less seasonally.

Some caution was required in order not to corrupt the handling of subroutine calls, interrupts, the machine stack, and so on.

Some platforms provide library calls which allow run-time dynamic allocation from the C stack rather than the heap ( e. g. Unix, Microsoft Windows CRTL's ).

Some of the locomotives were fitted with the cylindrical Elesco feedwater heater before the smoke stack, while others used a Worthington unit with its rectangular box in the same location.

Some rules use unlimited center stacks-they are only removed when the draw stack is depleted.

Some machines have a stack of very limited size, implemented as a register file and a dynamic register renumbering scheme.

Some machines have a stack of unlimited size, implemented as an array in RAM accessed by a ' top of stack ' address register.

Some stack machine instruction sets are intended for interpretive execution of a virtual machine, rather than driving hardware directly.

Some in the industry believe that stack machines execute more data cache cycles for temporary values and local variables than do register machines.

Some virtual machines support a general purpose permutation primitive, " PICK ," which allows one to select arbitrarily any item in the data stack for duplication.

Some simple stack machines have a chip design which is fully customized all the way down to the level of individual registers.

Some Burroughs stack machines do support up-level refs directly in the hardware, with specialized address modes and a special ' display ' register file holding the frame addresses of all outer scopes.

Some programming languages include a primitive for explicitly putting data on the stack, usually called PUSH.
