Chicamocha canyon wind energy potential and VAWT airfoil selection through CFD modeling

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2020
The use of vertical axis wind turbines (VAWT) in Colombia could tackle the energy distribution difficulties as large parts of the territory are not connected to the electrical grid.

Dynamical Gelfand-Zetlin algebra and equivariant cohomology of Grassmannians

open access: yes, 2016
We consider the rational dynamical quantum group $E_y(gl_2)$ and introduce an $E_y(gl_2)$-module structure on $\oplus_{k=0}^n H^*_{GL_n\times\C^\times}(T^*Gr(k,n))'$, where $H^*_{GL_n\times\C^\times}(T^*Gr(k,n))'$ is the equivariant cohomology algebra $H^

Resolution Dependence of Tropical Poleward Energy Transport in Aquaplanet GCMs

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 12, December 2025.
Abstract The tropical atmosphere plays an important role in transporting energy poleward and driving the global circulation. However, understanding and simulating this fundamental aspect of our climate remains difficult due to its sensitivity to convective parameterizations and horizontal resolution.

How does the market price pension accruals? [PDF]

open access: yes, 2007
We use a cross-sectional valuation model that distinguishes between the operating and financial activities of the firm to examine the repercussions of three main alternative measures of pension expense.

Screening of a long-term sample set reveals two Ranavirus lineages in British herpetofauna.

open access: yesPLoS ONE, 2017
Reports of severe disease outbreaks in amphibian communities in mainland Europe due to strains of the common midwife toad virus (CMTV)-like clade of Ranavirus are increasing and have created concern due to their considerable population impacts.

Normalization of twisted Alexander invariants

open access: yes, 2015
Twisted Alexander invariants of knots are well-defined up to multiplication of units. We get rid of this multiplicative ambiguity via a combinatorial method and define normalized twisted Alexander invariants.

Anomalous Gauge Boson Couplings in the e^+ e^- -> ZZ Process

open access: yes, 2000
We discuss experimental aspects related to the $\mathrm{e^+ e^-} \to \mathrm{Z}\mathrm{Z}$ process and to the search for anomalous ZZV couplings (V$= \mathrm{Z}, \gamma$) at LEP2 and future $\mathrm{e^+ e^-}$ colliders. We present two possible approaches

Forward and inverse kinematics of double universal joint robot wrists [PDF]

open access: yes
A robot wrist consisting of two universal joints can eliminate the wrist singularity problem found on many individual robots. Forward and inverse position and velocity kinematics are presented for such a wrist having three degrees of freedom.
