English

Subject field(s)
  • Artificial Intelligence
DEF

A production system is a human or computer system that has a data base of production rules and some control mechanism that selects applicable production rules in an effort to reach some goal state.

CONT

A key notion in the Newell-Simon scheme is the production system, in which an operation will be carried out if a certain specific condition is met. Programs consist of long sequences of such production systems operating on the data base. As described by the theorists, the production system is kind of a computational stimulus-response link; so long as the stimuli(or conditions) are appropriate, the response(or production) will be executed. In the course of developing the General Problem Solver, Simon and Newell have propounded a perspective on artificial intelligence, a theory of thinking, and an agenda for future research.

CONT

A set of production rules (which is called a production system) can be interpreted in two distinct ways. ... One way to interpret a production system is to work through the rules one by one until a rule is found for which the condition ... is true. ... Alternatively, the production system could be "run backwards", with the rules being run from "right to left".

OBS

A production system is a rule- based system. Computer scientists also call these systems general rewrite systems. Each rule is matched to the input, and the rules that apply rewrite the input according the action part of these rules.

Subject field(s)
  • Loads and Loading (Motor Vehicles)
  • Road Traffic
  • Transportation
CONT

The general theory of structures is based on a static calculation, which means to say that both the structure and the loads acting on it are at rest, or may simulate this condition because they act slowly. But the structure and load acting on it cannot always be deemed to be at rest, because the dynamic effect of forces may cause accelerations in it, which lead to failure. Wind and earthquakes are forces with a significant dynamic effect on bridges but it must also be borne in mind that traffic loads are moving and, in fact, the dynamic effect of these loads are taken into account via impact factors...

Many physicists assume that gravitons exist, but few think that we will ever see them. These hypothetical elementary particles are a cornerstone of theories of quantum gravity, which seek to unify Albert Einstein's general theory of relativity with quantum mechanics. But they are notoriously hard — perhaps impossible — to observe in nature.

The hypothetical number of years spent in perfect health which could be considered equivalent to the actual number of years spent in a defined imperfect state of health.

OBS

To overcome the shortcomings of the QALY [quality-adjusted life year]... propose a measure which does not constrain the relationship between quality and quantity and claim that it truly reflects a person's preferences over quantity and quality of life while retaining the intuitive appeal of the concept of the year in full health.... it is more consistent with EUT [expected utility theory] and hence with individuals’ preferences. To distinguish it from the QALY they have named their new measure the healthy year equivalent(HYE). It involves the valuation of whole health profiles, which vary in terms of the sequence and duration of health states. This is a more general measure of preferences than the QALY since it makes fewer assumptions.

A base in chemistry is a substance that can accept hydrogen ions or more generally, donate electron pairs. A soluble base is referred to as an alkali if it contains and releases hydroxide ions(OH−) quantitatively.

Subject field(s)
  • Biological Sciences
DEF

Study of the rate at which a reaction proceeds and of the reaction mechanism, the intermediate steps constituting the overall reaction. The reaction rate is the rate of change of the concentrations of a reactant or product expressed in moles per liter per second (mol/1-sec.). It varies with temperature, and the presence (or absence) of catalyst, and the concentration of one or more products or other molecular species. When these conditions are fixed, it is equal to the rate constant for the reaction multiplied by the product of the concentration of the reactants, with each concentration raised to a specific power.

CONT

In 1913 a general theory of enzyme action and kinetics was developed by L. Michaelis and M. L. Menten, which was later extended by G. E. Briggs and J. B. S. Haldane.

Natural law(or law of nature). The belief in natural law and natural law theories has been one of the most ancient and persistent themes in philosophy, and in legal history and theory.

Vitesse de croissance du nombre de boules-unités de rayon donné, ou de cubes de côté uniforme, nécessaire à recouvrir un ensemble borné, à mesure que ce rayon décroît.

OBS

La différence entre la dimension de Hausdorff et la densité logarithmique tient au fait que dans un cas on utilise des recouvrements par des boules égales, alors que dans l'autre, on autorise des recouvrements plus complexes. C. Tricot (1981) donne douze définitions possibles de la densité logarithmique.

Just as the cell doctrine has proved central in biology, and germ theory is pivotal in the area of disease, so the concept of physical symbol system is deemed by Simon and Newell and their colleagues at Carnegie-Mellon as the core doctrine in the area of computer science. Proceeding in Boolean spirit, the job of the theorist is to identify that set of processes which operates on symbolic expressions in order to produce other expressions that create, modify, reproduce, and/or transform symbolic structures. A physical symbol system is necessary and sufficient to carry out intelligent actions; and, conversely, any system that exhibits general intelligence will prove upon analysis to be a physical symbol system. Such a system consists of a control, a memory, a set of operations, and input and output : its input consists of objects in certain locations; its processes are operations upon the input; its output is the modification or re-creation of objects in certain locations.

Jeu d'entités (formes physiques) qui peuvent se manifester comme composantes d'un autre type d'entité (expression, structure de symboles). A chaque instant, le système contient un assemblage de ces structures et un ensemble de processus pour produire d'autres structures par création, modification, reproduction ou élimination. Dans le temps, le système est une machine qui produit un assemblage évolutif de structures de symboles. Selon l'hypothèse fondamentale de l'intelligence artificielle (Newell et Simons), cet assemblage possède les moyens nécessaires et suffisants pour une action intelligente.

Anderson has been working for many years on ACT(Adaptive Control of Thought), a general theory of cognition with a particular emphasis on skill acquisition. As a recent version, ACT(ACT-star) has satisfied many of his initial ambitions, his group started a special interdisciplinary project involving both psychologists and computer scientists at C MU : the Advanced Computer Tutoring Project(ACTP).

VanLehn spends very little of his voluminous dissertation on demonstrating the coverage of his theory. Most of his effort goes into underlining its principled construction. First, he traces the performance of his model to a restricted set of sufficient principles, emphasizing that his design is transparent with respect to them. Second, he argues that these principles are necessary to the theory for empirical and explanatory adequacy by comparing them with potential competitors in what he calls competitive argumentation. In this context, it becomes essential to have well-defined processes by which modifications to the underlying principles propagate through the theory, via the kind of global constraints called entailments in REPAIR theory. VanLehn is now advocating his competitive argumentation as a general methodology for validating AI-based theories of human cognition(VanLehn et al., 1984). One of his central claims is that the contributions of a solid argumentation may well outlive the theory it was meant to support.

DEF

a theory asserting that the laws of physics are identical in all inertial frames. It follows that the speed of light cannot be different in different frames, even if they are in relative motion. Thus the speed of light is a universal constant. Special relativity predicts a number of effects such as time dilation, length contraction and mass increases.

CONT

The topics are beyond the scope of this book but it is worth mentioning that Einstein's theory of special relativity deals with inertial frames, while his theory of general relativity deals with accelerated frames.
