Numerical methods to compute stresses and displacements from cellular forces: Application to the contraction of tissue

We consider a mathematical model for skin contraction, which is based on solving a momentum balance under the assumptions of isotropy, homogeneity, Hooke's Law, infinitesimal strain theory and point forces exerted by cells. However, point forces, described by Dirac Delta distributions lead to a singular solution, which in many cases may cause...

Point forces in elasticity equation and their alternatives in multi dimensions

Deep dermal wounds induce skin contraction as a result of the traction forcing exerted by (myo)fibroblasts on their immediate environment. These (myo)fibroblasts are skin cells that are responsible for the regeneration of collagen that is necessary for the integrity of skin We consider several mathematical issues regarding models that...

Study of the sound escape with the use of an air bubble curtain in offshore pile driving

Underwater noise pollution generated by offshore pile driving has raised serious concerns over the ecological impact on marine life. To comply with the strict governmental regulations on the threshold levels of underwater noise, bubble curtains are usually applied in practice. This paper examines the effectiveness of an air bubble curtain...

Betweenness: Tangible & Intangible boundaries for formulating a complex estate landscape in Gelders Arcadie

Connection and separation, or synthesis and dissolution, to draw on Georg Simmel’s expression, are each the precondition of the other. It lightens me to rethink the core of boundary. In the estate landscape of Veluwe Zoom, the elites and noble use flowing water, shrubs, walls, fences to declare their own territory and maintain bridge, passage to...

Underwater Noise Generated By Offshore Pile Driving: A Pile-Soil-Water Vibroacoustic Model Based On A Mode Matching Method

In this paper, a pile-water-soil model is developed for the prediction of sound generated due to impact piling. The complete model consists of two modules: i) a near-source module aiming at the accurate description of the pile-water-soil interaction together with the sound generation and propagation in the vicinity of the pile; and ii) a far...
