Dielectric resonators' main use is in millimeter-wave electronic oscillators (dielectric resonator oscillator, DRO) to control the frequency of the radio waves generated. They are also used as bandpass filters as well as antennas .
Differential reinforcement of alternative behavior (DRA) - A conditioning procedure in which an undesired response is decreased by placing it on extinction or, less commonly, providing contingent punishment, while simultaneously providing reinforcement contingent on a desirable response. An example would be a teacher attending to a student only ...
The Delta Regional Authority (DRA) is a Federal-State partnership whose mission it is to improve the quality of life for the residents of the Mississippi Delta. The Delta Regional Authority serves 252 counties and parishes in parts of eight states: Alabama , Arkansas , Illinois , Kentucky , Louisiana , Mississippi , Missouri , and Tennessee .
The dominant account of extinction involves associative models. However, there is debate over whether extinction involves simply "unlearning" the unconditional stimulus (US) – Conditional stimulus (CS) association (e.g., the Rescorla–Wagner account) or, alternatively, a "new learning" of an inhibitory association that masks the original excitatory association (e.g., Konorski, Pearce and ...
ABA is an applied science devoted to developing procedures which will produce observable changes in behavior. [3] [9] It is to be distinguished from the experimental analysis of behavior, which focuses on basic experimental research, [10] but it uses principles developed by such research, in particular operant conditioning and classical conditioning.
Dielectric resonator antenna; Dopamine receptor antagonist, first generation antipsychotics; Dopamine releasing agent, a class of drugs; Downregulated-in-adenoma, an anion exchanger
Archaeological site of Dra' Abu el-Naga, view to the west, Luxor West Bank, Egypt The necropolis of Draʻ Abu el-Naga' (Arabic: دراع ابو النجا) is located on the West Bank of the Nile at Thebes, Egypt, just by the entrance of the dry bay that leads up to Deir el-Bahari and north of the necropolis of el-Assasif.
In machine-shop terminology, the complete digital read-out system (consisting of a computer, axis-position encoders, and a numeric display) is referred to by the acronym DRO. Such a system is commonly fitted to machines in today's shops, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring ...
