Ethnologie brésilienne. Les voies d’une anthropologie indigène

open access: yesBrésil(s), 2016
In this article, we trace a movement that seeks to understand the current context of Brazilian ethnology. In dialogue with other descriptions produced over the last few decades, we address what we view as one of the most significant current developments ...

An economic hybrid J2 analytical orbit propagator program based on SARIMA models [PDF]

open access: yes, 2012
We present a new economic hybrid analytical orbit propagator program based on SARIMA models, which approximates to a 4 × 4 tesseral analytical theory for a Quasi-Spot satellite.

Analytical modelling of hot-spot traffic in deterministically-routed k-ary n-cubes [PDF]

open access: yes, 2005
Many research studies have proposed analytical models to evaluate the performance of k-ary n-cubes with deterministic wormhole routing. Such models however have so far been confined to uniform traffic distributions.

Analytical bias correction for two-step fixed effects models with copula-distributed errors [PDF]

open access: yes, 2022
We derive an analytical bias correction for two-step fixed effects models with copula-distributed errors. We work out the approximate bias correction for the Gaussian copula and present a numerical computation exercise for three other copula families ...
