Effect of the number of blades and solidity on the performance of a vertical axis wind turbine [PDF]

open access: yes, 2016
Two, three and four bladed phgr-shape Vertical Axis Wind Turbines are simulated using a free-wake vortex model. Two versions of the three and four bladed turbines are considered, one having the same chord length as the two-bladed turbine and the other ...

Impact of Blockchain Technology for Business and Information Systems: Automation of Inter-Company Debt Compensation Case Study

open access: yesApplied Sciences, 2023
Debt compensation is a process via which various entities (companies, people, etc.) propose the payment of their mutual debts by compensating them according to the credits they may have in their favor. The aim is to establish the financial information of

Seed Geometry in Species of the Nepetoideae (Lamiaceae)

open access: yesHorticulturae
The Nepetoideae are a subfamily of the Lamiaceae with 124 genera in three tribes: Elsholtzieae, Mentheae and Ocimeae. Their seeds have variable shapes, described in the literature by using adjectives derived from geometry, such as ellipsoid or elliptic ...

Solidity of viscous liquids. V. Long-wavelength dominance of the dynamics [PDF]

open access: yes, 2007
This paper is the fifth in a series exploring the physical consequences of the solidity of glass-forming liquids. Paper IV proposed a model where the density field is described by a time-dependent Ginzburg-Landau equation of the nonconserved type with ...
