This makes direct application of comprehensive air quality models such as the Community Multiscale Air Quality CMAQQ) modeling system impractical due to computational cost.
While a typical temporal measurement can provide measurements at up to 125 time gates, the use of all gates when solving the inverse problem in Eq. (4) is impractical due to computational and memory constraints.
As a consequence, the energy efficiency requirement is met for an extended operation time period due to computational load reduction.
However, the passive system design is such that failure is a rare event, which renders these approaches often impractical due to the computational efforts involved in the repetition of runs of the computer codes numerically encoding the system model.
Such optimization techniques are core to many robotics problems, but traditional approaches are inherently impractical due to their computational complexity.
When the scale of the training sample set is large and the parameter space is huge, the existing popular super-parameter selection methods are impractical due to high computational complexity.
In a real application DFT-RDM uses the discrete Fourier transform in a block-by-block basis instead of the full-sequence Fourier transform [5], which would be impractical due to its computational complexity and the memory required by RDM.
Consequently, combining a bagging technique with computationally intensive classification algorithms and gene extraction methods may become impractical due to high computational cost.
Until recently, the calculation of image charge on curved electrodes has been impractical due to the high computational cost, but this cost can be mitigated by parallelizing the calculations on general purpose graphic processing units (GPUs).
Even though the ML decoder is optimum, it is impractical due to its high computational complexity.
Apparently, solving (7) through brute force exhaustive signal sequence searching is impractical due to its formidably high computational complexity, which grows exponentially with the block length.
