A continuous performance task, continuous performance test, or CPT, is any of several kinds of neuropsychological test that measures a person's sustained and selective attention. Sustained attention is the ability to maintain a consistent focus on some continuous activity or stimuli , and is associated with impulsivity .
When talking about circuit bit rates, people will interchangeably use the terms throughput, bandwidth and speed, and refer to a circuit as being a '64 k' circuit, or a '2 meg' circuit — meaning 64 kbit/s or 2 Mbit/s (see also the List of connection bandwidths). However, a '64 k' circuit will not transmit a '64 k' file in one second.
Specify test data needed and charter effort (often overlooked, but vital to carrying out a valid performance test). Develop proof-of-concept scripts for each application/component under test, using chosen test tools and strategies. Develop detailed performance test project plan, including all dependencies and associated timelines.
The performance of a 512-node Anton machine is over 17,000 nanoseconds of simulated time per day for a protein-water system consisting of 23,558 atoms. [5] In comparison, MD codes running on general-purpose parallel computers with hundreds or thousands of processor cores achieve simulation rates of up to a few hundred nanoseconds per day on the ...
The test functions used to evaluate the algorithms for MOP were taken from Deb, [4] Binh et al. [5] and Binh. [6] The software developed by Deb can be downloaded, [7] which implements the NSGA-II procedure with GAs, or the program posted on Internet, [8] which implements the NSGA-II procedure with ES.
Nesplora Aula is a psychological test in virtual reality that measures attentional processes in children from 6 to 16 years of age. It is a level III C Continuous Performance Test (CPT) that combines auditory and visual stimuli in a virtual environment: a school classroom, alive and organic, with the distractors of that environment.
Frequency analysis [2] is the analysis of how often, or how frequently, an observed phenomenon occurs in a certain range. Frequency analysis applies to a record of length N of observed data X 1, X 2, X 3. . . X N on a variable phenomenon X. The record may be time-dependent (e.g. rainfall measured in one spot) or space-dependent (e.g. crop ...
The most straightforward scheme uses a digital counter and a free-running crystal oscillator to time intervals with 1-clock ambiguity, resulting in output edge jitter of one clock period peak-to-peak relative to an asynchronous trigger. This technique is used in the Quantum Composers and Berkeley Nucleonics instruments.
