Ethics and materials. Some Spanish Case Studies

In Navea, north of Spain, a medieval arch bridge shows a visible distortion (fig.1a). A stone falls down from the web of a gothic vault in a big parish church in Burgos (fig. 1b), and a voussoir falls down from the rib of another gothic vault in Oviedo (fig. 1c). An oval dome collapses in Zaragoza, though another four identical domes remain safe (fig. 1d). Sometimes the building has to support new, heavier loads. The ruin of the abandoned (since the 19th Century) monastery of Melón should be consolidated, some vaults are rebuilt and the visitors can walk over them. A Franciscan Convent is going to be turned into a Cultural Centre, the loads to be supported being multiplied by a factor of two. A little medieval bridge is asked to support the pass of heavy lorries. These are some of the cases I have studied in the last two decades, all of them referring to questions of structural safety. These are the kind of situations which often occurs in the field of Historic Structures. They require a study and an answer. This is no scholarly work (though in some cases new lines of future research will emerge). A judgement must be made by the expert and this judgement affects the safety and economy, in the last instance, of people. As there are rarely unique answers, the behaviour of the expert, then, can also be judged as "ethical", if he proposes an intervention that is necessary and adequate (or, recommends no intervention, judging the situation safe), or "non-ethical", if recommends an unnecessary or disproportionate intervention. In relation to the monument, also, the proposal can be judged ethically; any intervention damaging seriously the character of the monument may be labelled un-ethical.

Technological development in Spanish gothic vaults design

The principle of complexity as the evolution vector of the gothic style was an idea largely developed by Paul Frankl. The high complexity reached in the 15th and 16th centuries was possible thanks to the geometrical resources developed in the workshops of the medieval stonemasons. The search for more sophisticated designs was possible also with the higher standardization, so that the most complex ribbed vault could be built with ribs that had all the same curvature and with voussoirs that were therefore identical. Spanish Gothic architecture has been deeply studied from a historical and artistic point of view. The present paper, as a complement to these analyses, aims to point out some of the geometrical methods and technological improvements that late medieval masons were able to develop. In that way, some selected vaults have been measured, in order to study their geometry and design process. Also scale models of some vaults have been built at the Escuela de Arquitectura (Madrid) to validate these geometrical principles. More than just a research method, the scale models allow to understand the medieval construction techniques, and they are a powerful pedagogical tool with which pupils can reach a rewarding experience based on the “medieval-way” praxis.

Mixed models for short-run forecasting of electricity prices: Application for the Spanish market

Short-run forecasting of electricity prices has become necessary for power generation unit schedule, since it is the basis of every profit maximization strategy. In this article a new and very easy method to compute accurate forecasts for electricity prices using mixed models is proposed. The main idea is to develop an efficient tool for one-step-ahead forecasting in the future, combining several prediction methods for which forecasting performance has been checked and compared for a span of several years. Also as a novelty, the 24 hourly time series has been modelled separately, instead of the complete time series of the prices. This allows one to take advantage of the homogeneity of these 24 time series. The purpose of this paper is to select the model that leads to smaller prediction errors and to obtain the appropriate length of time to use for forecasting. These results have been obtained by means of a computational experiment. A mixed model which combines the advantages of the two new models discussed is proposed. Some numerical results for the Spanish market are shown, but this new methodology can be applied to other electricity markets as well

Impact of introducing longer and heavier vehicles on regional consumer price index and Spanish road freight transport system

This paper applies an integrated modeling approach to the case of Spain; the approach is based on a random utility-based multiregional input-output model and a road transport network model for assessing the effect of introducing longer and heavier vehicles (LHVs) on the regional consumer price index (CPI) and on the transportation system. The approach strongly supports the concept that changes in transport costs derived from the LHV allowance as well as the economic structure of regions have direct and indirect effects on the economy and on the transportation system. Results show that the introduction of LHVs might reduce prices paid by consumers for a representative basket of goods and services in the regions of Spain and would also lead to a reduction in the regional CPI. In addition, the magnitude and extent of changes in the transportation system are estimated by using the commodity-based structure of the approach to identify the effect of traffic changes on traffic flows and on pollutant emissions over the whole network.
