Assessing mechanical properties of the cardiovascular system
(University of Missouri--Columbia, 2020)
The elasticity of wall of the arteries plays a significant role in cardiovascular system. Capacitance of the aorta is predicative of cardiovascular events[1]. To get better understanding the function of the cardiovascular ...
Optimization of electromagnetic acoustic transducers for nondestructive evaluation of concrete structures
(University of Missouri--Columbia, 2008)
There are more than 130,000 prestressed concrete bridges in the United States with about 37,000 bridges being more than 30 years old. Prestressing steel strands are an important construction element used in these bridges ...
Dynamic study of the piezo-driven pipettes in intracytoplasmic sperm injection
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Intracytoplasmic Sperm Injection (ICSI) is regarded as a critical assisted reproductive technology (ART) procedure in which a single spermatozoon is mechanically injected...
Elastic property prediction of long fiber composites using a uniform mesh finite element method
(University of Missouri--Columbia, 2008)
This research numerically evaluates elastic non-isotropic material properties of fiber reinforced composite materials. Calculations are performed with a finite element mesh composed of a uniform array of three dimensional ...
