For a linear time-invariant black box, let for notational convenience: the step response can be obtained by convolution of the Heaviside step function control and the impulse response h ( t ) of the system itself

For time-invariant linear systems in the state space representation, a convenient test to check if a system is observable exists.

For example, the term is used to describe systems such as verlan and louchébem, which retain French syntax and apply transformations only to individual words ( and often only to a certain subset of words, such as nouns, or semantic content words ).

For example, autopilot systems that are prolific today were started to help bomber planes fly steadily enough to hit precision targets from high altitudes.

For a time, the combined company retained the Burroughs processors as the A and V systems lines.

For example, an information systems specialist will view computing somewhat differently from a software engineer.

For example, programming language theory studies approaches to description of computations, while the study of computer programming itself investigates various aspects of the use of programming languages and complex systems, and human-computer interaction focuses on the challenges in making computers and computations useful, usable, and universally accessible to humans.

For instance, NASA has extremely rigorous software testing procedures for many operating systems and communication functions.

For example, programming language theory considers various approaches to the description of computation, whilst the study of computer programming itself investigates various aspects of the use of programming language and complex systems.

For example, kinship and leadership function both as symbolic systems and as social institutions.

For very large systems, the relative total energies can be compared using molecular mechanics.

For π-electron systems, this was the Hückel method proposed by Erich Hückel, and for all valence electron systems, the extended Hückel method proposed by Roald Hoffmann.

For example, the conservation of energy follows from the time-invariance of physical systems, and the fact that physical systems behave the same regardless of how they are oriented in space gives rise to the conservation of angular momentum.

For some distributed parameter systems the vectors may be infinite-dimensional ( typically functions ).

For simplicity, the following descriptions focus on continuous-time and discrete-time linear systems.

For example, there is a hard disk, from which most operating systems run and on which most store their files.

For instance, on newer MS Windows computers, the older FAT-type file systems of MS-DOS and old versions of Windows are supported, in addition to the NTFS file system that is the normal file system for recent versions of Windows.

For continuous, frequent or prolonged intravenous chemotherapy administration, various systems may be surgically inserted into the vasculature to maintain access.

For example, Burris has reviewed sociological publications and used the theories of Weber and Bourdieu to describe academic caste systems.

For this reason it is not hard to port games between these systems.

For embedded systems, the highest performance levels are often not needed or desired due to the power consumption requirements.

For a while hybrid cable / electric systems operated, for example in Chicago where electric cars had to be pulled by grip cars through the loop area, due to the lack of trolley wires there.

For microscopic, atomic-level systems like a molecule, angular momentum can only have specific discrete values given by

For one thing, this is not a subject often discussed or analyzed.

For better or for worse, we all now live in welfare states, the organizing principle of which is collective responsibility for individual well-being.

For one thing, there is a natural belt of rock across the river bed ; ;

For the family is the simplest example of just such a unit, composed of people, which gives us both some immunity from, and a way of dealing with, other people.

Even so astute a commentator as Harold Clurman of The Nation has said that `` Waiting For Godot '' is `` the concentrate of the contemporary European mood of despair ''.

For one thing, the world that Beckett sees is already shattered.

Harold Clurman is right to say that `` Waiting For Godot '' is a reflection ( he calls it a distorted reflection ) `` of the impasse and disarray of Europe's present politics, ethic, and common way of life ''.

For the beatnik, like the hipster, is in opposition to a society that is based on the repression of the sex instinct.

For this reason, too, their language is more forthright and earthy.

For the present it is enough to note that in the grotesque figure of Jacoby, at the moment of his collapse, all these elements come together in prophetic parody.

For Plato, `` imitation '' is twice removed from reality, being a poor copy of physical appearance, which in itself is a poor copy of ideal essence.

For both Plato and Aristotle artistic mimesis, in contrast to the power of dialectic, is relatively incapable of expressing the character of fundamental reality.

For Hammer, nothing is forbidden.

For example, suppose a man wearing a $200 watch, driving a 1959 Rolls Royce, stops to ask a man on the sidewalk, `` What time is it ''??

For the occasion on which everyone already knows everyone else and the host wishes them to meet one or a few honored newcomers, then the `` open house '' system is advantageous because the honored guests are fixed connective points and the drifting guests make and break connections at the door.

For this change is not a change from one positive position to another, but a change from order and truth to disorder and negation.

For paradigmatic history `` breaks '' rather than unfolds precisely when the movement is from order to disorder, and not from one order to a new order.

For this love of the boy for his mother is a hopeless and forbidden love, doomed by its nature.

For innocence, of all the graces of the spirit, is I believe the one most to be prayed for.

For what we propose, however, a psychoanalyst is not necessary, even though one aim is to enable the reader to get beneath his own defenses -- his defenses of himself to himself.

For this purpose a degree of intellectual and emotional involvement is necessary ; ;
