Parallelizing remote sensing image geometric correction

Remote sensing spatial, spectral, and temporal resolutions of images, acquired over a reasonably sized image extent, result in imagery that can be processed to represent land cover over large areas with an amount of spatial detail that is very attractive for monitoring, management, and scienti c activities. With Moore's Law alive and well, more and more parallelism is introduced into all computing platforms, at all levels of integration and programming to achieve higher performance and energy e ciency. Being the geometric calibration process one of the most time consuming processes when using remote sensing images, the aim of this work is to accelerate this process by taking advantage of new computing architectures and technologies, specially focusing in exploiting computation over shared memory multi-threading hardware. A parallel implementation of the most time consuming process in the remote sensing geometric correction has been implemented using OpenMP directives. This work compares the performance of the original serial binary versus the parallelized implementation, using several multi-threaded modern CPU architectures, discussing about the approach to nd the optimum hardware for a cost-e ective execution.

Els àmbits de pràctica professional en els estudis de psicologia: present i futur

Els alumnes de Psicologia, quan inicien els seus estudis universitaris, sovint tenen una imatge parcial i esbiaixada de l’ampli ventall de possibilitats professionals de què disposa el psicòleg en l’àmbit aplicat. Seria desitjable que aquestes representacions inicials anessin modificant-se al llarg dels estudis per anar-se apropant als perfils existents en la pràctica professional.Els plans d’estudi anteriors a la reforma del Espai Europeu d’Educació Superior difícilment assolien aquest objectiu en l’àmbit de la Psicologia: una llicenciatura estructurada en àrees de coneixement, no sempre directament vinculades a perfils professionals, i poques hores de pràctica en centres aplicats, hi contribuïen clarament. Però les múltiples reformes que planteja la convergència europea a nivell d’estudis superiors, introdueixen un seguit de modificacions importants al respecte que poden resultar avantatjoses: l’increment de les hores de pràctiques tutelades en centres aplicats, tant en els estudis de Grau i com de Màster, així com la clara correspondència entre, d’una banda, els perfils professionals de la Psicologia i, per una altra, els quatre Màsters que s’ofereixen a Espanya, en són alguns exemples. El present article analitza, no només el curs de la reforma de la titulació de Psicologia en l’estat espanyol en relació als àmbits de pràctica professional, si no que també recull els que es contemplen en el marc universitari de la convergència europea, partint de la directrius de l’interessant projecte EuroPsy (European Diploma of Psychology).Finalment, es reflexiona sobre les àrees de pràctica professional envers les àrees d’especialització en Psicologia, així com de les òptimes perspectives de creixement que presenta la professió en un futur immediat

Anàlisi geomètrica del Diaclasat de les Guilleries en el sector de la Vall del Ter entre els embassaments del Pasteral i Susqueda (Girona)

The Guilleries are a small and mountainous area located in the north-westem part of the Catalonian Coastal Ranges where metamorphic and igneous Paleozoic rocks are exposed. After the main hercynian folding this area was affected by a brittle deformation that is mainly manifested by the intrusion of a very large number of dykes of granodiorite and the development of a complex joint system. Trends of dykes indicate that their intrusion was related to a SE-NW extension, whose estimated value is 40% on an average. This extension seems to stand, although without any associated igneous event, with the development of NE-SW directed joints which make the main set. Five families more were developed later, onegently-dipping and fou upright; the latter trending roughly SE-NW, ENE-WSW, ESE-WNW and N-S. AU the joint sets appear in the metasedimentary Paleozoic rocks and in the hercynian intrusive bodies. Concerning the ages, joints that belong to the NE-SW and SE-NW directed sets and also those slightly dipping have been attributed to the late-hercynian times and all the other are considered to be later

Morfogénesis del valle de Sant Miquel de Campmajor

A series of circumstances which converge in a little valley in the province of Girona, result in a peculiar type of morphogenetic evolution and a quite singular mechanical instability of its buttons. Very recent tectonic movements as well as dissolution phenomena of its subsoil due to pressurized underground water have played an important role in the morphogenesis. Such conditions have resulted in a fast morphological evolution which a progressive lowering of the valley floor as well as peculiar morphological features which favour the existence of numerous pits caused by sudden collapses distributed in altitude and time

Geología del Montgrí

This paper, fundamentally stratigraphic, is based on the vertical distribution of fauna in sediments which constitute the Montgri Massif. The stratigraphic series is composed of two units: one allochtonous (Mesozoic) and a second one autochtonous (Paleogene). The latter crops out in front of the thrust belt and presents the typical facies described by PALLI (1972). The allochtonous part is formed by the following units (from bottom to top): variegated gypsiferous shales of Keuper age; marls, limestones and dolomites from the Lias (Domerian); gray breccia ted dolomites: supraliassic; and Cretaceous limestones with rare interbeds of calcareous marls and nodular shaly marls. In this unit the Neocomian, Barremian (?), Aptian, Albian, Cenomanian, Turonian (?) and Santonian haven been recognized. Structurally, the Montgri Massif is part of a thrust belt which has been divided into three parts of different development ang age. Both parts are affected by ample synclinal folds of NE-SW directions and fractures of NW-SE orientation. The fractures condition the torrential streams as well as the karstic phenomena present in the Massif. These and the eolian actions are the main causes of the present geomorphology of the Montgri

Estudio sobre la resistencia quimica de baldosas ceramicas no-esmaltadas para pavimentos industriales

The chemical resistance of ceramic tiles is the subject of the European Standard UNE-EN ISO 10545-13. In order to evaluate the effect of aqueous solutions of several chemicals agents on the aspect of the tile surface, this standard establishes a series of tests at room temperature followed by visual inspection. According to this standard the tiles of this study are classified as being of maximum resistance (UHA). However operating conditions can be more aggressive than those detailed in the standard. So, a systematic study has been undertaken. In the present work, the effect of aqueous solutions of several organic and inorganic acids on the tile surface is evaluated. Samples immersed in different solutions are subjected to the following conditions: T= 60º C; pH=2 and to agitation processes. Visual analysis, as well as optical microscopy and scanning electron microscopy (SEM) were performed in order to determine the possible variation of the superficial aspect of tiles. Moreover, atomic absorption spectrophotometry has been used in order to obtain quantitative information concerning the solubility of system M (III)-L (M= Fe; L= H2O or L= ligand). The results obtained show, in all cases, a progressive dissolution of iron oxide precipitates presents in the ceramic body
