Fifty lateral radiographs of normal wrists were viewed to determine the palmar cortical angle of the distal radius.
Calculation of the jumping distance according to the frontal cup inclination angle, the anteversion angle, the radius of the head (R) and the head offset.
By employing the concept of velocity instant center, the cam profile, the path of cutter, the pressure angle and the radius of curvature of the cam can be expressed parametrically, and the follower motion of the remaining stroke can be analyzed analytically.
Upon application of a tension of ∼60 V, the contact angle changes, the radius of curvature is modified, the luminous rays are focused (Fig. 22b).
Independent but not blinded evaluators administered the DASH quality-of-life questionnaire at postoperative months 6 and 24, performed functional assessment of pain, range of motion, and palm grip strength, and radiographic examinations (volar and radial angle, and height of the radius) before the operation, immediately afterwards, and at 6 and 24 months postoperative.
Parametric analyses are carried out to study the influence of the rotation velocity, the stagger angle and the radius of the disk on the eigenfrequencies of the pretwisted blade.
where, is the angle, is the radius of the binary image, and is the distance from a centroid of the binary image.
To evaluate the relationship between thoracic kyphosis and vertebral derotation, the thoracic kyphosis angle (T5-12), the radius of the thoracic curvature, and the vertebral rotation angle at the apex were measured before and after the two different simulated corrections for each patient.
where β is the angle between the line connecting the top of the debris waves at both sides of the section and a horizontal line, δ is the slope angle of the flow path, R is the radius of curvature and g is the gravity acceleration.
We model the network area denoted by ψ (α,R,N,k) using a sector with the angle of α and radius R which is divided into N cells from the perspective of lifetime properties(N network cells) and is divided into k cells from the perspective of node density (k node cells).
