Timecourse of a perceptual judgment and factors affecting it
… but also related motor and other non-decision delays involved in a choice. To resolve this, the compelled-saccade (CS) task was developed. The CS task is a two-alternative forced-choice task with a crucial difference: the instruction to initiate a saccade (GO signal) precedes cue presentation, …

Measuring trapped-ion motional decoherence through direct manipulation of motional coherent states
… consists of two coherent displacements with a variable phase difference in a continuous harmonic oscillator phase-space, separated by a variable delay time. Using a strontium-88⁺ ion trapped 50 micrometers above a niobium surface electrode trap in an ultra-high vacuum chamber at 4 Kelvin, we …

Design, Characterization and Application of a Multiple Input Stethoscope Apparatus
… signals of interest were explored using variable-delay beam forming. S1 and S2 heart sound recognition with optimized beam forming delays and inter-symbol noise elimination were investigated for improved discernment of the S1 or S2 heart sounds by a user. Also, stereophonic presentation …

EFFECTS OF DIAZEPAM, D-AMPHETAMINE, AND MORPHINE ON RATS’ CHOICES BETWEEN FOOD ALONE AND FOOD WITH DELAYED SHOCK
… immediate reinforcing consequences followed by delayed aversive consequences are commonly associated with failures in “self-control”. The present study evaluated acute effects of diazepam, <em>d</em>-amphetamine, and morphine on rats’ choices using a variable-delay procedure that arranged …

Effect of variable transmission delays with a prediction cue on operator performance in a simplified simulated docking task
… a simulated space vehicle was affected by variable transmission delays; and (2) to determine if an approximate predictor cue enhanced the operator's ability to control the vehicle. The study employed two independent variables, delay variability and prediction. There were four levels, or …

Study on Zero Crossing Detection in CRM Totem-pole PFC Converter
… with zero-crossing detection are detection delay and noise immunity. A delay in turning off the synchronous switch due to ZCD delay results in a large negative current and an overall increase in ripple current, reducing efficiency. ZCD delay is also variable, as it depends on the operating …

Effects of sample-set size on delayed-matching-to-sample
… of university students was assessed using a Delayed-Matching-to-Sample task. White disks, presented on computer screens, served as stimuli. For the general DMTS task, used here, a sample stimulus was presented to the participant. After a variable delay (0.05, 4, 8 or 16 s) two comparison …

Analysis of construction and stakeholder risks for Public Private Partnership projects in developing countries : a comparative analysis using Artificial Neural Networks to determine the effect of poor stakeholder management and construction risks on the project’s schedule (PPP vs. traditional projects)
… from government, force majeure and permits delays are affecting PPP projects in all the countries included in this research. It is also noticed that risks affecting developed countries such as Hong Kong, China and UK are of similar nature to the risks affecting developing countries. The …

Nonlinear Dynamics and Chaos in Systems with Time-Varying Delay
Systeme mit Zeitverzögerung sind dadurch charakterisiert, dass deren zukünftige Entwicklung durch den Zustand zum aktuellen Zeitpunkt nicht eindeutig festgelegt ist. Die Historie des Zustands muss in einem Zeitraum bekannt sein, dessen Länge Totzeit genannt wird und die Gedächtnislänge festlegt. In …
