چکیده

(A) A T2 image of a human lumbar spine IVD disc. (B) FA map obtained from the DTI data. Notice the difference in FA signal between the anterior and posterior parts of the IVD with the yellow highlighted square indicating the lamellae’s anisotropic behavior, also viewed histologicaly in figure (C). Notice the substantial gaps between the lamellae appearing in this region. (D) The site of connection between a gibbon’s AF fibers and the IVD endplate. Notice the irregular shape of the lamellae and the fact that not all of them terminate at the end plate. The different noticeable colored layers are due to their opposing orientations as they cross each other.

Novel Radial Basis Function Neural Networks based on Probabilistic Evolutionary and Gaussian Mixture Model for Satellites Optimum Selection

In this study, two novel learning algorithms have been applied on Radial Basis Function Neural Network (RBFNN) to approximate the functions with high non-linear order. The Probabilistic Evolutionary (PE) and Gaussian Mixture Model (GMM) techniques are proposed to significantly minimize the error functions. The main idea is concerning the various strategies to optimize the procedure of Gradient ...

Developing a Novel Temperature Model in Gas Lifted Wells to Enhance the Gas Lift Design

In the continuous gas lift operation, compressed gas is injected into the lower section of tubing through annulus. The produced liquid flow rate is a function of gas injection rate and injection depth. All the equations to determine depth of injection assumes constant density for gas based on an average temperature of surface and bottomhole that decreases the accuracy of gas lift design. Also g...

Constitutive Modeling and Damage Mechanics of the Annulus Fibrosus

by Nathaniel T. Hollingsworth Annulus fibrosus damage has been shown to come from combinations of bending, lifting, and twisting. Although the these motions can induce annulus fibrosus damage, the stress-strain state of the annulus during these motions is not known. The objective of this project was to develop more complete constitutive models and to investigate annulus fibrosus damage mechanic...
