Presence of late decelerations with fewer than 50% of contractions or significant variable decelerations. Requires repeat testing on following day. [1] Equivocal—Tachysystole: Presence of contractions that occur more frequently than every 2 minutes or last longer than 90 seconds in the presence of late decelerations.
Nuchal cord, when the umbilical cord is (tightly) around the neck of the fetus [2]; Entanglement of the cord [2]; Knot in the cord [2]; Cord prolapse, where the umbilical cord exits the birth canal before the baby, which can cause cord compression.
Variables on the material points: positions, velocities, strains, stresses etc. are then updated with these rates depending on integration scheme of choice and a suitable constitutive model. Resetting of grid. Now that the material points are fully updated at the next time step, the grid is reset to allow for the next time step to begin.
When variable decelerations are associated with uterine contractions, their onset, depth, and duration commonly vary with successive uterine contractions. [citation needed] Prolonged deceleration: a decrease in FHR from baseline of at least 15 bpm, lasting at least 2 minutes but less than 10 minutes. A deceleration of at least 10 minutes is a ...
The tslearn Python library implements DTW in the time-series context. The cuTWED CUDA Python library implements a state of the art improved Time Warp Edit Distance using only linear memory with phenomenal speedups. DynamicAxisWarping.jl Is a Julia implementation of DTW and related algorithms such as FastDTW, SoftDTW, GeneralDTW and DTW barycenters.
Deceleration ramp down — positive jerk limit; linear increase in acceleration to zero; quadratic decrease in velocity; approaching the desired position at zero speed and zero acceleration Segment four's time period (constant velocity) varies with distance between the two positions.
The accordion effect in road traffic refers to the typical decelerations and accelerations of a vehicle when the vehicle in front decelerates and accelerates. These fluctuations in speed propagate backwards and typically get bigger and bigger further down the line, resulting in reduced throughput of road traffic. [1]
A nonstress test can be classified as normal, atypical, or abnormal. A normal nonstress test will show a baseline fetal heart rate between 110 and 160 beats per minute with moderate variability (5- to 25-interbeat variability) and 2 qualifying accelerations in 20 minutes with no decelerations.
