TDTOPTW is NP-hard while almost the whole body of the related literature addresses the non-time dependent version of the problem.
By its applicative nature, several versions of this problem have been considered, such as dynamic, time-dependent versions (see e.g. [5]).
The proportional hazards assumption was checked by including time-dependent versions of all the covariates in the models.
A time-dependent version of the peak over threshold (POT) approach is used to build the model, which is then applied to specific reanalysis time series and NOAA buoy records.
We also present a static, single-period, formulation of the single-node problem that appears as a subproblem when addressing the time-dependent version and general service network design cases.
This makes Eq. (16) identical to the 1D time-dependent version of the continuity equation.
Fraceschetti et al. [10] propose a model for the time-dependent version of PRP that considers traffic congestion.
The function (V x)) represents the potential acting on the particle and (W x)) represents a particle-interaction term, which avoids spreading of the wave packets, in the time-dependent version of the above equation.
We used the time-dependent version of Cox regression in order to consider the different time-periods: before odor onset, during and one second after the 4 s odor presentation and after the odor presentation.
The continuous wavelet transform equations perform a time-frequency decomposition of the signal yielding a time-dependent version of the typical low- and high-frequency peaks (31, 32).
As the LETGS calibration team has monitored the accelerated rate of decay in the HRC-S quantum efficiency as a function of wavelength, they have elected to replace the current set of time dependent QE Uniformity (QEU) files (version N0009) with another new set of files, version N0010.
