On the bicanonical map of irregular varieties

From the point of view of uniform bounds for the birationality of pluricanonical maps, irregular varieties of general type and maximal Albanese dimension behave similarly to curves. In fact Chen-Hacon showed that, at least when their holomorphic Euler characteristic is positive, the tricanonical map of such varieties is always birational. In this paper we study the bicanonical map. We consider the natural subclass of varieties of maximal Albanese dimension formed by primitive varieties of Albanese general type. We prove that the only such varieties with non-birational bicanonical map are the natural higher-dimensional generalization to this context of curves of genus $2$: varieties birationally equivalent to the theta-divisor of an indecomposable principally polarized abelian variety. The proof is based on the (generalized) Fourier-Mukai transform.

En este informe se describe el trabajo de fin de máster, centrado en el estudio de la gamificación como herramienta de aprendizaje aplicada a dispositivos móviles. Se ha realizado una revisión de los artículos científicos que tratan sobre el tema de la gamificación como herramienta educativa, para terminar el trabajo desarrollando un prototipo de juego para el aprendizaje de mapas de Karnaugh. Se ha optado por un desarrollo multiplataforma y se han revisado los frameworks de desarrollo más populares para desarrollo móvil multiplataforma, así como los motores de juegos aplicables a este caso. Tras la implementación, se ha probado el prototipo en dos sistemas operativos móviles libres: Android y Firefox OS.

Abstract

Geological observation in southeastern Zanskar and adjacent Lahul area (northern Himalaya).

The paper deals with the stratigraphic and structural setting of the sedimentary sequence cropping out in southeastern Zanskar and adjacent Lahul areas. The Tibetan Zone succession of southeastern Zanskar consists of about 6000 m of sediments, Late Precambrian~ ?Eocene in age, arranged in two superposed slabs (Pugh tal Unit, below, and Zangla Unit, above) tectonically resting upon the High Himalayan Crystalline. The Pughtal sequence, mostly terrigenous with carbonate units in the Cambrian, Silurian and Carboniferous, is about 2500 m thick. It was deposited from ?Late Precambrian to Carboniferous or ?Early Permian. The Permian Panjal Traps constitute the "sole" of the Zangla Unit, whose sedimentary sequence, about 3000 m thick, mainly carbonatic, spans from Late Permian (Kuling Formation) to Middle Jurassic (Kioto Limestone) in eastern Zanskar. In the Zangla area Late Jurassic/Cretaceous formations (Spiti Shales, Giumal Sandstone, Chikkim Limestone) are also present. Towards northwest, the sequence ranges up to Paleocene (Spanboth Formation) and ?Eocene (Chulung La Slates). Au nord de la Haute Chaine, dans la partie septentrionale de I'Himalaya, la marge continentale indienne a vu plus de 6000 m de sediments se deposer depuis I'Infracambrien jusqu'a I'Eocene. Lors de l'orogenese himalayenne, ces sediments ont ete decolles de leur substratum originel, dMormes et metamorphises de maniere differenciee suivant leur position. Ils reposent en contact tectonique sur la nappe cristalline du Haut-Himalaya. L'unite inferieure ou unite de Pughtal consiste, la ou elle est complete, en plus de 2500 m de sediments en partie detritiques terrigenes mais marque par l'edification de plates-formes carbonatees au Cambrien, Silurien et Carbonifere. Dans cette unite on releve deux grandes sequences sedimentaires separees par l'evenement epirogenique et magmatique tardi-Cambrien (500 rna), contrecoup de l'orogenese pan-africaine. Un niveau massif de vo1canites basaltiques permiennes ~ les Panjal Traps ~ forme la base ou sole de I'unite superieure (nappe de Zangla). Cette unite, plissee de maniere disharmonique, recouvre progressivement vers l'ouest des niveaux de plus en plus anciens de l'unite inferieure, niveaux eux-memes replisses en grands plis couches kilometriques a vergence nord. Dans la partie occidentale (Ringdom) l'unite superieure repose directement sur la nappe cristalline. Cette unite montre une serie sedimentaire avec des carbonates de plate-forme bien developpes au Trias superieur et au Lias puis des sediments surtout pelagiques et en partie detritiques terrigenes au Jurassique superieur et au Cretace. Des la fin du Cretace et jusqu'au Paleocene superieur s'edifie a nouveau une plate-forme peu profonde. La serie se termine par des couches continentales attribuees a l'Eocene. L'evolution geodynamique durant Ie Paleozoique et Ie Mesozoique est analysee. II en ressort que la sedimentation, a partir de I'Ordovicien, est regJee plus par des grands cycles eustatiques que par des mouvements tectoniques ou epirogeniques regionaux (les orogeneses caledoniennes, hercyniennes et cretacees des auteurs).

The coal bearing Cenozoic As Pontes Basin (NW Spain): Geological influence on its coal's characteristics

Lignite deposits in the Cenozoic As Pontes strike-slip basin (northwestern Spain)were formed as a function of specific paleoclimatic conditions and tectonic evolution of the basin.

Matkapuhelinverkon MAP-protokollatoteutus älyverkkopalveluiden ohjauspisteeseen

Työssä esitellään yleiseurooppalaisen GSM-matkapuhelinjärjestelmän verkkoelementtejä ja perehdytään niiden väliseen standardoituun merkinantoprotokollaan. Lisäksi tarkastellaan protokollan lyhytsanomien välitykseen liittyviä operaatioita ja niissä tapahtunutta kehitystä standardoinnin eri vaiheissa. Tavoitteena oli toteuttaa GSM-matkapuhelinverkon merkinantoprotokollaan perustuva ohjelma, jonka tehtävänä on välittää lyhytsanomia matkapuhelin- ja lyhytsanomakeskuksen välillä. Matkapuhelimeen päättyvän lyhytsanoman välitykseen liittyy lisäksi reititystiedon hakeminen vastaanottajan kotirekisteristä. Toteutuksessa on ohjelmointirajapinta, joka helpottaa matkapuhelinverkon uusien palvelusovellusten kehittämistä. Toteutus testattiin standardoituja testitapauksia soveltaen. Yhdenmukaisuustestauksessa käytettiin apuna merkinantoanalysaattoria. Testauksessa tarkastettiin, että protokolla toimii loogisesti oikein. Suorituskykyä ei ole voitu testata todellisessa testiympäristössä, mutta ohjelmallisesti toteutettujen simulaattoreiden avulla on saatu hyviä tuloksia.
