Studies in History and Philosophy of Science Part C: Studies in History and Philosophy of Biological and Biomedical Sciences, 2005
Philosophers of science increasingly believe that much of science is concerned with understanding the mechanisms responsible for the production of natural phenomena. An adequate understanding of scientific research requires an account of how scientists develop and test models of mechanisms.

Investigation of interface shear properties and mechanical model between ECC and concrete
Construction and Building Materials, 2019This paper reveals an investigation of the influences of ECC mixture construction method (i.e., common casting and spraying ECC), ECC strength grade, interface roughness of concrete substrate, and polyvinyl alcohol (PVA) fiber type on shear properties of

Acoustical Modeling of Swallowing Mechanism
IEEE Transactions on Biomedical Engineering, 2011In this paper, a mathematical modeling of the swallowing sound generation is presented. To evaluate the model, its application on swallowing disorder (dysphagia) diagnosis is discussed. As a starting point, a simple linear time invariant model is assumed to represent the pharyngeal wall and tissue excited by a train of impulses.

Frost-heaving mechanical model for concrete face slabs of earthen dams in cold regions
Cold Regions Science and Technology, 2019Earthen dams are widely applied in the cold regions of northern China. However, the frost-heaving damage of concrete face slabs on the dam slopes is very serious under the dual effect of ice sheets and frost action during winter seasons. For this problem,

Modeling the Mechanical Parameters of Glaucoma
Tissue Engineering Part B: Reviews, 2019Glaucoma is a major eye disease characterized by a progressive loss of retinal ganglion cells (RGCs). Biomechanical forces as a result of hydrostatic pressure and strain play a role in this disease. Decreasing intraocular pressure is the only available therapy so far, but is not always effective and does not prevent blindness in ...

The loading process among the silicon substrate, silica cluster and polyurethane pad was performed by molecular dynamics simulations. The results showed that the interaction force between the cluster and pad did not change with the working pressure at ...

Fully coupled fluid‐electro‐mechanical model of the human heart for supercomputers
International Journal for Numerical Methods in Biomedical Engineering, 2018In this work, we present a fully coupled fluid‐electro‐mechanical model of a 50th percentile human heart. The model is implemented on Alya, the BSC multi‐physics parallel code, capable of running efficiently in supercomputers.
