Conformal proper times according to the Woodhouse causal axiomatics of relativistic spacetimes

On the basis of the Woodhouse causal axiomatics, we show that conformal proper times and an extra variable in addition to those of space and time, precisely and physically identified from experimental examples, together give a physical justification for the `chronometric hypothesis' of general relativity. Indeed, we show that, with a lack of these latter two ingredients, no clock paradox solution exists in which the clock and message functions are solely at the origin of the asymmetry. These proper times originate from a given conformal structure of the spacetime when ascribing different compatible projective structures to each Woodhouse particle, and then, each defines a specific Weylian sheaf structure. In addition, the proper time parameterizations, as two point functions, cannot be defined irrespective of the processes in the relative changes of physical characteristics. These processes are included via path-dependent conformal scale factors, which act like sockets for any kind of physical interaction and also represent the values of the variable associated with the extra dimension. As such, the differential aging differs far beyond the first and second clock effects in Weyl geometries, with the latter finally appearing to not be suitable.Comment: 25 pages, 2 figure

Metodología para mejorar el análisis de datos satélite radar en el estudio de los movimientos de ladera: sierra de Tramuntana (Mallorca)

En el presente trabajo se presenta una metodología para mejorar el análisis de datos de desplazamientos de la superficie del terreno obtenidos mediante técnicas de interferometría diferencial avanzada (A-DInSAR) en el estudio de movimientos del terreno. En particular, se ha realizado un análisis de los movimientos del terreno con distintos satélites en la Sierra de Tramuntana (Mallorca). La metodología propuesta consta de tres partes principales. En la primera se propone un modelo previo al procesado DInSAR que determina cuales son las zonas idóneas para estimar desplazamientos del terreno. En la segunda parte, se propone un modelo posterior al procesado DInSAR en el que se proyecta el vector de desplazamiento obtenido en la línea de vista (LOS) de los distintos satélites, en función de la geometría del terreno. Así mismo se propone un método para determinar los rangos de estabilidad de los desplazamientos observados, Finalmente se realiza una validación de los datos de desplazamiento postprocesados para identificar movimientos de ladera activos y actualizar el inventario de los deslizamientos en la zona de estudio

The climate of the mediterranean region : from the past to the future

The aim of this chapter is to introduce the main topics in the Mediterranean circulation research and to give a general description of the Mediterranean Sea variability. Its scope is to provide information that is important for a comprehensive view of the most relevant issues concerning climate, which is a coupling between atmosphere and sea. The chapter describes data, research results, and key findings that have been reported in the most recent literature about the Mediterranean Sea circulation. The issue about sea level is considered in Chapter 4. The chapter also includes, in its concluding section, a discussion of the main open issues in Mediterranean Sea research
