DIRECT CURRENT CONTROL [6 records]

Record 1 2023-05-16

English

Subject field(s)
  • Orbital Stations
CONT

The Solid State Power Control Module(SSPCM) delivers 120 volts DC [Direct Current] from the Station to the racks and converts it to 28 volts DC, and delivers that power to a three-outlet power strip for use by the payloads. The SSPCM sends 120 volts DC to the RIC [Rack Interface Controller], the AAA [Avionics Air Assembly], and the PEHB [Payload Ethernet Hub/Bridge]. The SSPCM also provides data interfaces for payloads, including analog(two for each middeck locker and one for each ISIS [International Subrack Interface Standard] drawer) and bidirectional discrete(three for each middeck locker and two for each ISIS drawer).

OBS

solid state power control module; SSPCM: term and abbreviation officially approved by the International Space Station official approval Group (ISSOAG).

English

Subject field(s)
  • Urban Furnishings and Equipment
  • Illumination Engineering
CONT

Street Lighting. Traffic routes are lighted by lanterns giving a very carefully controlled distribution of light, usually mounted on columns at heights of 25-35 ft... Street lighting involves several problems of electrical distribution and control for which a variety of solutions has been used, such as constant current series distribution(mainly in U. S. A.) or parallel distribution with various methods of control such as cascade circuits, control by relays actuated by superimposed high frequency or D. C. [direct current], and time switches.

Éclairage des voies de circulation. Pour les voies à circulation automobile caractérisée, la prédominance est à l'automobile et l'on s'efforcera de donner au conducteur les meilleures conditions de vision de nuit en réalisant un éclairage adapté aux chaussées. Toutefois, lorsque ces voies s'inscrivent dans un contexte urbain, on se souciera tout particulièrement du traitement des nombreux carrefours et points de conflits ainsi que de l'environnement.

Record 5 1989-09-18

English

Subject field(s)
  • Artificial Intelligence
  • Continuing Education
DEF

In a bite-sized architecture of the tutoring module, combination of diagnostic and didactic purposes into adaptive sequences of hemistically generated tasks. This supplements sequencing optimization à la BIP with diagnostic information based on issues à la WEST, in the context of a learner-oriented organization of knowledge à la genetic graph.

CONT

MHO(Lesgold et al., 1987) is a system for learning principles of electricity that supports both free exploration and guided problem solving. Its tutoring component exploits the curriculum organization to implement the concept of steering testing. When it takes control of the interaction, MHO dynamically generates tasks-electrical circuits and questions about them-that have to fulfil two conditions. First, observing the student's performance on each task should maximize the information made available concerning possible changes in her knowledge state. Second, each task should concentrate on elements of the curriculum that are in the current focus so that diagnostic information can direct the course of instruction.
