The motion of a vocal fold is modelled with two mechanical resonators. One is for the translational movement of the body of the fold and is driven by the spatial average pressure in the glottal constriction. The other is rotational, it models the covering mucosa and is driven by the axial pressure gradient. Unlike the classical Ishizaka-Flanagan two-mass model, these resonators are mechanically...

Introduction What are the key attributes of an effective IL educator? What difficulties do students encounter in using online information resources? These are the types of qualitative questions that Critical Incident Technique (CIT) is well suited to exploring. This chapter outlines the origins, ongoing development, implementation, advantages and disadvantages of Critical Incident Technique and...

An analysis is carried out to investigate the magnetohydrodynamic flow and heat transfer in an unsteady flow of Eyring-Powell fluid over an oscillatory stretching surface. The radiation effects are also considered in energy equation. The flow is induced due to infinite elastic sheet which is stretched periodically back and forth in its own plane. Finite difference scheme is used to solve dimens...

Verification of multithreaded programs is difficult. It requires reasoning about state spaces that grow exponentially in the number of concurrent threads. Successful verification techniques based on modular composition of overapproximations of thread behaviors have been designed for this task. These techniques have been traditionally described in assume-guarantee style, which does not admit rea...

James L. Flanagan J ames (Jim) L. Flanagan was born 26 August 1925 and grew up on a cotton farm in Greenwood, Mississippi. He graduated from high school in 1943 and completed his freshman year at Mississippi State University before joining the U.S. Army at age 18. He returned home about three years later, picked up his studies with the help of the G.I. Bill, and graduated with a B.S. degree in ...

In the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. Effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

A method for controlling the grasping force when an object is grasped by artificial elastic fingers is proposed. First, the relationship between the stick area and the internal strain distribution of the finger is calculated using FE (finite element) analysis. Based on this relationship, a method is proposed for controlling the grasping force by decreasing the increasing ratio of the tangential...

The immersed boundary method is a computational framework for problems involving the interaction of a fluid and immersed elastic structures. Immersed boundary computations typically evaluate the elastic forces explicitly in the configuration of the immersed elastic structure. In many applications this results in a severe restriction on the time step. We present a semi-implicit and a fully impli...

Elastotic degeneration in cases of pterygium, as in pinguecula, is characterized by the appearance of vermiform, coiled, and knotty fibres which take up elastic stain, but these so-called elastic fibres appear to differ from natural elastic tissue. There are certain skin diseases in which an apparent increase in elastic fibres is seen (Tunbridge, Tattersall, Hall, Astbury, and Reed, I952). Gill...
