In the new method, observations prior to an earthquake are utilized to establish a precise ionospheric delay prediction model, so that precise co-seismic displacements can be obtained without any convergence process.
Precise delay rates in turn allow a proper prediction of the particles' delays (7), so that in the end much fewer particles are needed to represent the a posteriori density, as the delay spread of the particles during the importance sampling is kept much smaller, since delay hypotheses, which do not match the delay rates are not generated during the importance sampling.
Thus, another mechanism is required to make more precise delay calculations.
For high accuracy, the second method requires precise delay compensation, and the accuracy severely decreases when clocks are chained [1].
When the same filtering solution is used for precise delay estimation (i.e., code tracking), the target is clearly below 0.1 chip residual timing error.
Because the precise delay between hip arthroplasty and complications during the index hospitalization was not available in the database, we used logistic regression analysis with the first occurrence of a complication as endpoint instead of a Cox proportional hazards model.
Several timing constructs were introduced by concatenating "nops" to produce precise delays, up to a delay of 31.25us (500 clock ticks) at a time.
The Ground Control was initiated with a precise 6 day delay to enable the OES environment to be programed with those environmental conditions that can be replicated on the ground, such as cabin temperature and CO2 levels, taken from ISS telemetry.
This 5V square-wave signal is an ideal source for producing an accurate time base, because its rising and falling edges happen at a precise period without much delay, and it oscillates from 0 to 5V, which are TTL values that can be fed into the MCU.
The duration of data gap bridged by this technique could be possibly extended if a more precise atmospheric delay prediction is found or on-the-fly (OTF) technology is applied.
The patchwork standards of each county in Florida contributed to the difficulty last year in arriving at a precise tabulation of votes, delaying the results for 36 days.
