The Weber criteria relates the position of the distal
01/10/2022 · In this study, a spiral groove hydrodynamic bearing (SGB) is applied with two distinct objectives: first, as a mechanism to enhance the washout in the secondary flow path of a centrifugal RBP, lowering the exposure to high shear stresses and avoiding thrombus formation; and second, as a way to allow smaller gaps without compromising the washout
A thrust bearing of a scroll compressor plays an important role in reliability and efficiency of the scroll compressor. In the case of high-side shell type scroll compressors, the back pressure mechanism without tip-seals is adopted for the sealing in the axial direction between a fixed scroll and an orbiting scroll.
the Spiral of Archimedes, which is defined by the simple equation: r = aθ, where r is the radius from a fixed center, a is a constant and θ is the angle (in polar coordinates). Other variants include the hyperbolic spiral, parabolic spiral, logarithmic spiral and involute spiral. If we add a third dimension to a simple spiral, the
15/08/2022 · In this paper, hybrid particle swarm optimization with a spiral-shaped mechanism (HPSO-SSM) is proposed for selecting the optimal feature subset for classification via a wrapper-based approach. In HPSO-SSM, we make three improvements: First, a logistic map sequence is used to enhance the diversity in the search process.
10/08/2022 · Aim. To study the application value of ankle fracture classification and diagnosis. In this paper, the clinical data of 100 cases of ankle fracture patients admitted from May 2022 to May 2022 were analyzed by CT 3D reconstruction. All patients received surgical treatment and underwent spiral CT 3D reconstruction and X-ray examination before surgery.
After the fracture of the leg and its plaster cast removal, the most important concern of the patient is when will they resume walking. For this, they have to follow proper tibia fibula fracture rehabilitation protocol. In this article, we are going to learn about step-by-step physiotherapy exercises after tibial shaft fracture.
Table 7-2 Commonly used diametral pitches . Instead of using the theoretical pitch circle as an index of tooth size, the base circle, which is a more fundamental circle, can be result is called the base pitch p b, and it is related to the circular pitch p by the equation (7-8) Condition for Correct Meshing. Figure 7-5 shows two meshing gears contacting at point K 1 and K 2.
