Interaction Structure

Interaction Structure

 

(delaying structure), a wave-guide system in superhigh-frequency electronic devices; it is used to decelerate the phase velocity of electromagnetic waves to approximately the speed of movement of the electrons in the device. Because of this effect, an interaction structure creates the conditions necessary for the diversion of energy by waves moving parallel to the electron flow through a decrease in the kinetic energy of the electron flow. An increase in power is possible in cases of long-term interaction between the wave and the electron flow.

Interaction structures are of various designs. Spiral structures are widely used. The waves propagate along the conductor of the spiral with a velocity approaching the speed of light; however, the wave velocity along the spiral itself decreases, depending on the pitch of the spiral. Interaction structures are the basic design elements for traveling-wave and backward-wave tubes.

This figure exhibits a special interaction structure of a kink and a periodic wave.
The models often assumed that a population was partitioned into just a few subpopulations (by age, for example) and that there was a regular interaction structure within and between subpopulations.
Sinclair and Coulthard (1975) described the initiation-response-feedback (IRF) exchange structure as the basic interaction structure in the classroom.
In this interaction structure, boys and girls could both learn to be assertive, make demands and statements, and understand how the other gender communicates.

Viewing learning from this perspective causes us to develop an understanding of how tools and social interaction structure cognition, which means that learning must be investigated within the situations in which it occurs.
The above analyses yielded information on two features of these webs, species structure and interaction structure. Species structure was defined by the number of species (S), levels (L), and proportions of predators ([p.sub.p]), herbivores ([p.sub.h]), omnivores ([p.sub.o]), and basal species ([p.sub.b]).
On the other hand, pursuing the practical dimension and, at the same time, the fact that doctor--patient interaction structures were built mainly on empirical observations, searching permanently for concrete solutions in well-defined situations, the philosophical fundamental of interaction was gradually reduced and doctor--patient interaction became more and more fragmented.
Considering in turn the theory and the practice, he covers explanations in computational social sciences, observation and explanation in behavioral sciences, reasons for integration, behavioral agents, sophisticated agents, social networks and other interaction structures, and an example of application.
The topics include interaction structures and the development of early complex society in the region, from small household clusters to the central place of the Bogota chiefdom in Columbia, a multiscalar view on the evolution of social complexity in the Rio Parita Valley of central Pacific Panama, and household organization and communal feasts in the Panamanian village of El Hatillo.
More specifically, as MMIC power levels increase, the requirement for high gain inside the vacuum envelope can be alleviated, allowing smaller interaction structures. Tubes and ICs can indeed work together synergistically.
