Comparison of the Arithmetic and Geometric Means in Estimating Crown Diameter and Crown Cross-Sectional Area [PDF]

open access: yesSouthern Journal of Applied Forestry, 2010
Abstract The use of the geometric and arithmetic means for estimating tree crown diameter and crown cross-sectional area were examined for trees with crown width measurements taken at the widest point of the crown and perpendicular to the widest point of the crown.

Diameter Bounds on the Complex of Minimal Genus Seifert Surfaces for Hyperbolic Knot [PDF]

open access: yes, 2007
Given a link L in the 3-sphere, one can build simplicial complexes MS(L) and IS(L), called the Kakimizu complexes. These complexes have isotopy classes of minimal genus and incompressible Seifert surfaces for L as their vertex sets and have simplicial ...

On the Influence of Geometric Parameters of a Combined Orifice Valve on the Attainable Mean Droplet Diameter during High-Pressure Homogenization

open access: yesEngineering in Life Sciences, 2002
In order to meet the demands of the pharmaceutical and cosmetic industry for decreasing emulsion droplet sizes, new dispersing units are consistently developed. To obtain optimal results, thus the smallest possible droplet diameter and a narrow droplet size distribution at smallest possible energy input, the geometric parameters of a new dispersing ...

Predicting the risk of rupture for vertebral aneurysm based on geometric features of blood vessels [PDF]

open access: yes, 2021
A significant proportion of the adult population worldwide suffers from cerebral aneurysms. If left untreated, aneurysms may rupture and lead to fatal massive internal bleeding. On the other hand, treatment of aneurysms also involve significant risks. It
