Computers ( and computors ), models of computation: A computer ( or human " computor ") is a restricted type of machine, a " discrete deterministic mechanical device " that blindly follows its instructions.

" From these principles and some additional constraints —( 1a ) a lower bound on the linear dimensions of any of the parts, ( 1b ) an upper bound on speed of propagation ( the velocity of light ), ( 2 ) discrete progress of the machine, and ( 3 ) deterministic behavior — he produces a theorem that " What can be calculated by a device satisfying principles I – IV is computable.

A very simple model, involving discrete, deterministic responses, is considered here.

Global energy optimization can be accomplished using simulated annealing, the Metropolis algorithm and other Monte Carlo methods, or using different deterministic methods of discrete or continuous optimization.

According to whether all the model variables are deterministic, economic models can be classified as stochastic or non-stochastic models ; according to whether all the variables are quantitative, economic models are classified as discrete or continuous choice model ; according to the model's intended purpose / function, it can be classified as

The transfer operator of the Bernoulli map is exactly solvable and is a classic example of deterministic chaos ; the discrete eigenvalues correspond to the Bernoulli polynomials.

Thus eventually PDDL1. 2 captured the " physics " of a deterministic single-agent discrete fully accessible planning environment.

A discrete, deterministic computational process is said to be logically reversible if the transition function that maps old computational states to new ones is a one-to-one function ; i. e. the output logical states uniquely defines the input logical states of the computational operation.

2.3 the discrete stochastic process

In many cases it is not possible to divide the process into a finite number of discrete stages, since the state of the stream is transformed in a continuous manner through the process.

Theories of coregulation describe communication as a creative and dynamic continuous process, rather than a discrete exchange of information.

Petri nets and process algebras are used to model computer systems, and methods from discrete mathematics are used in analyzing VLSI electronic circuits.

Even if this process is more complex than analog processing and has a discrete value range, the application of computational power to digital signal processing allows for many advantages over analog processing in many applications, such as error detection and correction in transmission as well as data compression.

# the design process is understood in terms of a discrete sequence of stages.

Consider the communications process over a discrete channel.

Note also that in most spoken languages, the sounds representing successive letters blend into each other in a process termed coarticulation, so the conversion of the analog signal to discrete characters can be a very difficult process.

It used discrete transistors packaged in DEC's Flip-Chip technology, with backplanes wire wrapped via a semi-automated manufacturing process.

The brewing process for sake differs from the process for beer, in that for beer, the conversion from starch to sugar and from sugar to alcohol occurs in two discrete steps.

The waterfall model provides a structured approach ; the model itself progresses linearly through discrete, easily understandable and explainable phases and thus is easy to understand ; it also provides easily identifiable milestones in the development process.

* Parnas, David, A rational design process and how to fake it ( PDF ) An influential paper which criticises the idea that software production can occur in perfectly discrete phases.

Sampling is the process of converting a signal ( for example, a function of continuous time or space ) into a numeric sequence ( a function of discrete time or space ).

The theorem describes two processes in signal processing: a sampling process, in which a continuous time signal is converted to a discrete time signal, and a reconstruction process, in which the original continuous signal is recovered from the discrete time signal.

Reconstruction of the original signal is an interpolation process that mathematically defines a continuous-time signal x ( t ) from the discrete samples x ( nT ) and at times in between the sample instants nT.

Two discrete, sociological theories explain and justify gentrification as an economic process ( production-side theory ) and as a social process ( consumption-side theory ) that occurs when the suburban gentry tire of the automobile-dependent urban sprawl style of life ; thus, professionals, empty nest aged parents, and recent university graduates perceive the attractiveness of the city center — earlier abandoned during white flight — especially if the poor community possesses a transport hub and its architecture sustains the pedestrian traffic that allows the proper human relations impeded by ( sub ) urban sprawl.

A Bernoulli process is a discrete time process, and so the number of trials, failures, and successes are integers.

This transformation is uniquely determined by Af and we therefore speak of the process as deterministic.

The process in which the outcome of any one stage is known only statistically is also of interest, although for chemical reactor design it is not as important as the deterministic process.

The type of presentation of results used in the deterministic process may be used here, except that now the fourth column is redundant.

2.4 the continuous deterministic process

If this sounds indulgent, it allows simultaneity, absolute space and time and a deterministic universe ( along with decoherence theory ) whilst the status-quo permits time travel / causality paradoxes, subjectivity in the measurement process and multiple universes.

However, the concept of suppressing mutation raises the question: How can design evolution occur at the nanoscale without a process of random mutation and deterministic selection?

A handicap in this process is the difficulty of seeing and manipulation at the nanoscale compared to the macroscale which makes deterministic selection of successful trials difficult ; in contrast biological evolution proceeds via action of what Richard Dawkins has called the " blind watchmaker "

God knowing the future does not determine it as his knowledge is not a deterministic process emanating from the past but rather a knowledge that exists in the present and future actualized by human free action.

Pseudorandom sequences typically exhibit statistical randomness while being generated by an entirely deterministic causal process.

Such process is never deterministic.

Although the term implies suggestion, the process is deterministic, and done by executable code, essentially a special-purpose computer language.

Often the effort ( manpower, computer, and other resources ) required, the time limits on when the solution is needed, and the cost to compile, process, and analyze all the data required for deterministic or other complicated procedures preclude their usefulness or favor the faster, simpler heuristic approach.

This is the probabilistic counterpart to a deterministic process ( or deterministic system ).

Instead, a random process is a sequence of random variables describing a process whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability distributions.

Thus while the process is indeed deterministic, there is no better way to determine the being's will than to essentially run the experiment and let the being exercise it.

In spite of ARCNET's deterministic operation and historic suitability for real-time environments such as process control, the general availability of switched gigabit Ethernet and Quality of service capabilities in Ethernet switches has all but eliminated ARCNET today.

This process of influencing is never deterministic ; an occasion of experience consists of a process of comprehending other experiences, and then reacting to it.

In statistical signal processing and physics, the spectral density, power spectral density ( PSD ), or energy spectral density ( ESD ), is a positive real function of a frequency variable associated with a stationary stochastic process, or a deterministic function of time, which has dimensions of power per hertz ( Hz ), or energy per hertz.

h could be a constant, a deterministic function of time, or a stochastic process.

In order to make a deterministic process, mastering requires critical listening ; there are software mastering tools available to facilitate this last step, but results still depend upon the accuracy of speaker monitors.
