Short communication: Principal components and factor analytic models for test-day milk yield in Brazilian Holstein cattle
(Elsevier B.V., 2012-04-01)
A total of 46,089 individual monthly test-day (TD) milk yields (10 test-days), from 7,331 complete first lactations of Holstein cattle were analyzed. A standard multivariate analysis (MV), reduced rank analyses fitting the ...

Effective carrying capacity and analytical solution of a particular case of the Richards-like two-species population dynamics model
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We consider a generalized two-species population dynamic model and analytically solve it for the amensalism and commensalism ecological interactions. These two-species models can be simplified to a one-species model with ...
Comparison of factor-analytic and reduced rank models for test-day milk yield in Gyr dairy cattle (Bos indicus)
(2013-09-27)
We analyzed 46,161 monthly test-day records of milk production from 7453 first lactations of crossbred dairy Gyr (Bos indicus) x Holstein cows. The following seven models were compared: standard multivariate model (M10), ...

Analytical model to determine optimal production lots considering several productive and logistics factors
(Universidad Nacional de Colombia Sede Medellín, 2014-04-23)
The current economic crisis has led companies worldwide to pursue costs reductions in order to remain productive. To support this effort we propose an analytical model to establish the optimal lot size based on the celebrated ...
The Construction Site Management of Concrete Prefabricated Buildings by ISM-ANP Network Structure Model and BIM under Big Data Text Mining Analytic Network Process (ANP)
In the construction industry, prefabricated buildings have developed rapidly in recent years due to their various excellent properties. To expand the application of big data text mining and Building Information Model (BIM) ...
Factors and mass ratio analyses for Reactive Blue 19 dye decolorization using ozone: an experimental and analytical modelling approach
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2019-05-01)
Dyes highly reduce sunlight penetration into the stream, and consequently affect photosynthesis and oxygen transfer into water bodies. An experimental and analytical modelling approach to Reactive Blue 19 (RB19) removal ...
