Colombia using regionalization and scaling concepts with the long-term flow field as the scaling variable. All data sets, methods, and results are included in HidroSIG, an available interactive hydrologic atlas of Colombia.

a b s t r a c tIn this study we estimate the air leakage distribution of single-family dwellings in Catalonia and use a statistical analysis of an airtightness database for single-family dwellings in France to identify the building characteristics that have the greatest influence on airtightness. The most significant variables are found to be the structure type, the floor area, the age of the building, the number of stories and the insulation type. A multiple linear regression technique is then applied to establish a predictive model for deriving an estimated value of airtightness from these characteristics. To estimate the infiltration airflow, a stochastic simulation of the building characteristics was performed per census tract using real data on the distributions of building variables taken from the census information. The model is then applied to determine the power law coefficient and the airtightness distribution. The predicted flow coefficients are combined with the AIM-2 model and given meteorological conditions to determine the infiltration airflow. Two sets of meteorological conditions are considered: average conditions and extreme conditions for each season.

Audiovisual content found on digital technologies a natural expansion path, which has been accelerated thanks to the convergence. Mass Media strategies have focused on developing multiplatform content in order to exploit the potential distribution on the market. This article is about the theories and concepts related to measurement and cross-content, in turn, analyses one of the most ambitious multiplatform productions in Television de Catalunya, "Guernica: war paint." The purpose is to understand the scale of the issue from an interdisciplinary perspective and put the issues inherent in the study and analysis of cross-media productions. The text brings together the contributions of authors from different perspectives that have examined the content through concepts such as remediation, intertextuality, and transtextuality. The results indicate that the passage of pieces of content across different platforms used by television and radio operators happen more and more natural thanks to the experience accumulated over the past decade. The audience access multimedia motivated proposals complementary to television flow, attracted by the expansion of the contents and the establishment of a strong and proactive relationship with the audiovisual product. The documentary review escapes from the linear narrative and presents personalized and interactive content. However, we can speak of a hybridization between the total contents because the use of common tools and the degree of integration of technologies and production practices is still in an initial state.
