Therefore, a research which involved 40 subjects was carried out to obtain more knowledge in the field of steering movement while driving a car.
The near-field steering matrix is expressed by combining (9), (16), (18), and (19) as A N = Y Ω B N ⊙ Y Φ N, (20).
Therefore, by combining (9), (12), (13), and (14), the far-field steering matrix can be represented as A F = Y Ω B F Y Φ F. (15).
The far-field steering vector in the spherical harmonics domain is independent of the source range: y F Φ d = b 0 kR Y 0 0 Φ d ∗ b 1 kR Y 1 - 1 Φ d ∗ ⋯ b N kR Y N N Φ d ∗ T. (40).
According to the spherical harmonic representation of the sound field [40, 41], when sources are in the far-field of an array, the element aF l, d1, k) of the far-field steering matrix AF is independent of the source distance and can be expressed using spherical harmonics as a F l, d 1, k = ∑ n = 0 ∞ ∑ m = - n n b n kR Y n m ϑ d 1, φ d 1 * Y n m θ l, ϕ l, (12).
If near-field sources impinge on the spherical array, the element aN l, d2, k) of the near-field steering matrix AN can be expressed using spherical harmonics as a N l, d 2, k = ∑ n = 0 ∞ ∑ m = - n n b n d 2 kR, k r d 2 Y n m ϑ d 2, φ d 2 * Y n m θ l, ϕ l, (16).
The challenge for Mr. Mulally will be in ceding direct control of main subordinates to Mr. Fields, while still steering Ford through its European restructuring and Asian expansion.
These included (1) involvement of field staff in the generation of adaptations, (2) community acceptance measures, and (3) the role of the study steering committee, ethical review boards, and intervention sub-committees in their approval and implementation.
Besides steering the field's educational pathway, Philander has helped steer its scholarship as well.
In the free field, the steering vector of an M elements array at a frequency f and for a steering direction θ is known.
