In the early 1980s, suburbanization and periurbanization processes became widespread in major cities within Spain. An interesting stage of returning to city centers commenced that materialized in the start of rehabilitation policies within historic centers. These processes coincided with weak population growth, an acute industrial economic crisis, and new democratic policies in municipal councils. Three decades later, we may be witnessing similar processes, although with different origins. The consequences of a construction-based economic model have been disastrous in Spain, from both an economic as well as an environmental point of view. The artificial land boom was significant throughout the country, but was especially prominent within the Mediterranean areas that specialize in tourism and real estate (second homes). The burst of the real estate bubble has shown the irrationality of the economic model and the serious social and environmental consequences that the model has entailed. Within this context, some of the territorial transformation processes that occurred in Spain during the real estate boom period are being studied for the first time. Additionally, changes in land policies (urban renewal of centers and urban renewal in general) within the current economic and real estate crisis are analyzed. An urban rehabilitation that gradually includes new spaces for intervention and for introducing new sustainable methods for recovering degraded spaces, such as the Master Plan for Platja de Palma, a mature tourism destination that seeks a final ‘0 CO2 balance’ scenario, among other objectives.
The reliable predictions of liquid holdup and pressure drop are essential for pipeline design in oil and gas industry. In this study, the drift-flux approach is utilized to calculate liquid holdups. This approach has been widely used in formulation of the basic equations for multiphase flow ... more
Error bounds for nonlinear filtering are very important for performance evaluation and sensor management. This paper presents a comparative study of three error bounds for tracking filtering, when the detection probability is less than unity. One of these bounds is the random finite set (RF ... more
Current formulas for calculating scour depth below of a free over fall are mostly deterministic in nature and do not adequately consider the uncertainties of various scouring parameters. A reliability-based assessment of scour, taking into account uncertainties of parameters and coefficient ... more
