Assessment of Corneal Biomechanical Properties and Their Variation with Age
The cornea demonstrates considerable stiffening with age with the behavior closely fitting an exponential power function typical of collagenous tissue. Expand
Determination of the modulus of elasticity of the human cornea.
The material models developed in this work could be implemented in numerical simulations of refractive surgery procedures, corneal shape changes due to contact lens wear, and other applications. Expand

Numerical modelling based on finite element analysis is used to represent the biomechanical behaviour of the cornea and its use in modelling Goldmann applanation tonometry (GAT) is briefly described. Expand
Experimental Assessment of Human Corneal Hysteresis
The trend for hysteresis to decrease with age is in agreement with previous clinical observations and was also found to increase with faster pressure application. Expand
Evaluation of Goldmann Applanation Tonometry Using a Nonlinear Finite Element Ocular Model
Nonlinear modelling is shown to trace the behaviour of the cornea under both IOP and tonometric pressure, and to be able to provide additional, and potentially useful, information on the distribution of stress, strain, contact pressure and gap closure. Expand
Study on round rice straw bale wrapping silage technology and facilities
Specific to problems of the existing round bale wrapping machine in China, such as small application scope and failing to satisfy the wrapping demands of round bales of different specifications, aExpand
Large-deflection mathematical analysis of rectangular plates
A large-deflection mathematical analysis of rectangular plates under uniform lateral loading is presented in this paper. The analysis is based on solving two fourth-order, second-degree, partialExpand
Combined Effects of Cooled EGR and Air Dilution on Butanol–Gasoline TGDI Engine Operation, Efficiency, Gaseous, and PM Emissions
Exhaust gas recirculation (EGR) and air dilution were evaluated on a TGDI engine fueled with butanol–gasoline in view of engine operation, efficiency, gaseous emissions, and PM emissions. Expand
Experimental study on baling rice straw silage
Abstract: For resolving harvesting technology of fresh rice straw silage and plugging of the round steel-roll baler in China, experimental researches were carried out. For harvesting technology,Expand
Particulate matter (PM) emissions and performance of bio-butanol-methanol-gasoline blends coupled with air dilution in SI engines
Abstract This study was conducted to investigate PM emissions and performance of SI engines fueled with butanol-methanol-gasoline during air dilution operation. Iso-butanol and methanol were blendedExpand
