Sentence examples for directive model from inspiring English sources
Two pattern models [20] are implemented in this study: 1) a Lambertian model, with the maximum in the direction perpendicular to the surface; 2) a directive model, with the maximum in the direction of specular reflection . a Lambertian model, with the maximum in the direction perpendicular to the surface; a directive model, with the maximum in the direction of specular reflection.
By contrast, in the office scenario, the best result is achieved by a Directive model with a high value of αr, i.e., a narrow beam diffusion.
According to the results of the sensitivity test on scattering parameters, the chosen model is the Directive model with αr = 4 and S = 0.4, which gives an error of 4.8 dB with a standard deviation of 3.7 for XPR prediction and an absolute error of 5.8 ns with a standard deviation of 4.7 for delay spread prediction.
A similar conclusion has been drawn in [28] utilizing parameter extraction from the measurements performed in the same scenario, where strongest diffuse power components were found to be spatially co-located with specular channel components, which justifies the use of the directive model.
Three directive models, distinguished by αr values, are tested.
Considering XPR prediction, it is possible to conclude that the choice of S does not change the error significantly, but on the other hand, directive models with an higher value of αr seem to perform better.
Directive models of diabetes care often result in noncompliance and failure to produce the desired behavior and outcomes (35).
The columns entitled αr refer to a directive pattern model with the relative lobe width.
A directive scattering pattern model with scattering coefficient S = 0.4 and beamwidth α r = 4 has been chosen.
The OpenHMPP directive-based programming model offers a syntax to efficiently offload computations on hardware accelerators and to optimize data movement to/from the hardware memory.
