We study two-dimensional Banach spaces with polynomial numerical indices equal to zero.
A wedge-shaped structure made of split-ring resonators (SRR) and wires is numerically simulated to evaluate its refraction behavior. Four frequency bands, namely, the stop band, left-handed band, ultralow-index band, and positive-index band, are distinguished according to the refracted field distributions. Negative phase velocity inside the wedge is demonstrated in the left-handed band and the ...
Objective. To develop an additive numerical scoring scheme for the BILAG-2004 index. Methods. SLE patients were recruited into this multi-centre cross-sectional study. At every assessment, data were collected on disease activity and therapy. Logistic regression was used to model an increase in therapy, as an indicator of active disease, by the BILAG-2004 index score in the nine systems. As both...
In order to evaluate the accuracy of a numerical control machine tool comprehensively, the accuracy evaluation index system of a numerical control machine tool was established, and the priorities of accuracy indexes were determined by analytic hierarchy process method. Taking a five-axis numerical control machine tool for example, each accuracy index of it was studied by using fuzzy comprehensi...
