Impact of the deposition of different compounds in natural areas of Colombia dispersed from human activity emission sources through atmospheric teleconnections

Impact of the deposition of different compounds in natural areas of Colombia dispersed from human activity emission sources through atmospheric teleconnections: Initial characterization and analysis of satellite and ground data available. Andrés Yarce Botero Abstract: The Aburrá Valley (Colombia), due to its poor air quality, is becoming a source of contaminants that escape predominantly to the Northwest South America causing...

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes

Oaxaca-Blinder Type Counterfactual Decomposition Methods for Duration Outcomes. Andrés Felipe García-Suaza Abstract: Existing inference procedures to perform counterfactual decomposition of the difference between distributional features, applicable when data is fully observed, are not suitable for censored outcomes. This may explain the lack of decomposition exercises for variables related to duration outcomes, typically observed...

Normalization by Evaluation

Normalization by Evaluation. Andreas Abel. Abstract: In computer systems that manipulate syntactic objects, like computeralgebra systems, compilers, and theorem provers, we find algorithms that check whether two expressions are equal. Some expression classes admit normal forms. For objects of these classes, equality can be decided by checking that the expressions under consideration have the same normal form. Conversion to normal form...

Similarity-based clustering using a network analysis approach

Similarity-based clustering using a network analysis approach. Leandro Fabio Ariza Jiménez Abstract: Networks represent relations between objects connected pairwise. Networks can have community structure, that is, objects interacting in a network can be organized into groups called communities. In addition, objects forming a community probably share some common properties as well as play similar roles within the interacting phenomenon...
