We consider a composite material made up of hosting medium containing an ε-periodic array perfect thermal conductors. Comparing with the previous contributions in literature, present paper, inclusions are completely disconnected and form two families dissimilar physical behaviour. More specifically, imperfect contact between obeys different laws, according to types inclusions. The conditions in...

Contact thermal resistance is an important indicator of the efficiency heat transfer between contact interfaces.The interfaces superalloy GH4169 in high temperature was investigated byusing ANSYS. The real surface morphology obtained with optical microscope, and its modelwas reconstructed Based on theory structural mechanics, elastoplastic deformation microstructure interface simulated, analyze...

Vocal changes in emotional situations may identify contributing factors in behavioral voice disorders and direct more efficient therapies. Finding appropriate measures of voicing that detect emotional conditions is a first step in this line of investigation. The purpose of this study was to determine whether electroglottography (EGG) contact quotient is a viable measure to detect vocal changes ...

We show that in general, the specification of a contact angle condition at the contact line in inviscid fluid motions is incompatible with the classical field equations and boundary conditions generally applicable to them. The limited conditions under which such a specification is permissible are derived; however, these include cases where the static meniscus is not flat. In view of this situat...

We implanted an electronic knee prosthesis to measure tibial forces in vivo during activities of daily living after total knee arthroplasty. We used tibial forces and knee kinematic data collected in vivo to calculate contact stresses using finite element analysis. The polyethylene insert was modeled as an elastoplastic material, and predicted contact stresses were validated using pressure sens...

OBJECTIVES The aim of this study was to measure tear film surface quality (TFSQ) using dynamic high-speed videokeratoscopy during short-term (8 hrs) use of rigid and soft contact lenses. METHODS A group of 14 subjects wore 3 different types of contact lenses on 3 different nonconsecutive days (order randomized) in 1 eye only. The subjects were screened to exclude those with dry eye. The lense...
