As a parallel experiment of innovation involving economic, historical, and social components, artifacts define a universe of evolving properties that displays episodes of diversification and extinction. Here, we critically review previous work comparing the two types of evolution. Like biological evolution, technological evolution is driven by descent with variation and selection, and includes tinkering, convergence, and contingency. At the same time, there are essential differences that make the two types of evolution quite distinct. Major distinctions are illustrated by current specific examples, including the evolution of cornets and the historical dynamics of information technologies. Due to their fast and rich development, the later provide a unique opportunity to study technological evolution at all scales with unprecedented resolution. Despite the presence of patterns suggesting convergent trends between man-made systems end biological ones, they provide examples of planned design that have no equivalent with natural evolution Tue, 19 Mar 2013 13:42:15 GMT http://hdl.handle.net/2117/18405 2013-03-19T13:42:15Z Solé, Ricard; Valverde, Sergi; Rosas Casals, Martí; Kauffman, Stuart; Farmer, Doyne; Eldredge, Niles no Technology; Evolution; Tinkering; Convergence; Information technology; Culturomics Technological evolution has been compared to biological evolution by many authors over the last two centuries.

Changes in snowfall, glacier retreat and shifts in biodiversity amount and distribution are some examples of the sensitivity of mountain ecosystems. Moreover, in many mountain economies, reliable snow cover plays a key role as an important resource for the winter tourism industry, the main income source and driving force of local development in such regions. This study presents a georeferenced agent-based model to analyze the climate change impacts on the ski industry in Andorra and the effect of snowmaking as future adaptation strategy. The present study is the first attempt to analyze the ski industry in the Pyrenees region and will contribute to a better understanding of the vulnerability of Andorran ski resorts and the suitability of snowmaking as potential adaptation strategy to climate change. This study projects a reduction on the ski season length and the drop of the number of skiers especially in the lowest elevation ski resort of this region. Moreover, this work indicates that snowmaking cannot completely solve the problem of ensuring snow cover at low elevation ski resorts and should be considered as a suitable short-term strategy, but not as a sustainable long-term adaptation strategy. The resulting model can be used as a planning support tool to help local stakeholders understand the vulnerability and potential impacts of climate change and in the decision-making process of designing and developing appropriate sustainable adaptation strategies to future climate variability Mon, 19 Nov 2012 15:10:16 GMT http://hdl.handle.net/2117/16953 2012-11-19T15:10:16Z Pons Pons, Marc; Johnson, Peter A.; Rosas Casals, Martí; Sureda Carbonell, Bàrbara; Jover Comas, Eric no Climate change impacts, Winter tourism, Snowmaking, Adaptation, Agent-based modeling Mountain regions have been identified as especially vulnerable areas to climate change.

Great efforts have been made in order to reduce fossil energy consumption and mitigate its depletion by means of energy efficiency directives. The national transposition of such directives generates regional regulations that might be counterproductive if it is not clear which one is more restrictive. The main goal of this paper is to evaluate the potential of energetic savings of the dwellings in Catalonia and its economic impact, according to different scenarios of efficiency that have been defined according to current regulations at state and autonomic level. To achieve this objective, thirteen typologies of dwellings have been defined in order to categorize the stock of buildings in Catalonia. Simulations with LIDER software have been carried out in order to obtain the heating and cooling demand for each typology of dwelling in different climatic zones and orientations. The economic impact of each scenario has been stated as well. We show that the best normative scenario is not the regional but the national one, and only when full limitations imposed by the state regulations are fulfilled. Following the latter 6.4% reduction in CO2 emissions would be achieved, whereas following the former gives us only 2.8% reduction for year 2015. These results have been obtained considering a base case scenario without any energetic measures implemented for the same time line Wed, 10 Oct 2012 16:02:51 GMT http://hdl.handle.net/2117/16709 2012-10-10T16:02:51Z Garrido Soriano, Núria; Rosas Casals, Martí; Ivancic, Aleksandar; Álvarez del Castillo, María Dolores no Energy consumption in buildings accounts for a significant percentage of total world energy utilization.

Esta cuenca es de vital importancia porque es una de las últimas regiones prístinas de la Guayana venezolana. Los datos provienen de tres estaciones hidrométricas ubicadas en la cuenca del Río Caura. Se analiza la influencia del fenómeno El Niño Oscilación Sur (ENOS) y las anomalías de las temperaturas del océano Atlántico Tropical sobre los caudales del río. Para el análisis de las relaciones entre el fenómeno ENOS y la serie de caudales se utilizan los índices ONI y MEI. La exploración de las singularidades en los datos se realiza utilizando una segmentación de las series de tiempo basada en el índice ONI. La segmentación de la series de tiempo permite detectar relaciones específicas entre el caudal y cada una de las fases del fenómeno del Niño.
