The ratio τ transmission/τ total corresponds to the ratio between the pilot transmission duration and the pilot symbols transmission period N/L.
In the longer term, from 2025 onwards he believes we will see the "arrival of smart vehicles capable of fully autonomous navigation, with increased 'auto pilot' operating duration, plus the arrival of autonomous valet functions, delivering effortless vehicle parking and storage".
However, it has been suggested that channel measurements cannot be properly performed when such a short pilot symbol transmission duration is considered [31].
On average 98.27% CH4 conversion to syngas in reforming section comprising of a pre-reformer unit and a tri-reformer unit, and CO2 separation rate of 36.75% along with CO/H2 reduction from 2.67 to 2.08 in CO2 membrane separation section were achieved from the entire pilot plant operation duration of 450 h.
We compared, in a prospective, randomized pilot study, the duration of weaning of norepinephrine as determined by a closed-loop control based on fuzzy logic algorithm versus manual control by the clinician in patients with septic shock.
To validate our image categories and presentation durations, pilot data were collected from three radiologists at 250 ms and 500 ms durations two months before their participation in the experimental session.
where (boldsymbol {y}_{i}^{p}in {mathbb C}^{Mtimes tau }) with τ being the time duration of pilot transmission, and the matrix Φ i = ϕ1,…,ϕ K ) T contains the transmitted pilot sequences satisfying the power constraint (boldsymbol {Phi }_{i}boldsymbol {Phi }_{i}^{H}=mathbf {I}_{K}).
The preliminary nature of this pilot project, its limited duration and bounded conditions, and the bias inherent in some of the assessment must be acknowledged.
Also, restricting the pilot to 6 months duration is a major limitation as it typically takes longer for communities to reach maturity [ 3].
Limitations of the study primarily result from those inherent in a small pilot study of short duration that is designed primarily to determine intervention effect sizes on outcomes of interest, rather than to obtain definitive benefits.
