Contribuciones al procesado hardware de la señal para detectores de radiación de alta resolución espacial con lectura por matriz de fotodiodos : dise…

2013

Aplicaciones de física médica y nuclear para el diagnóstico por imagen o la radioterapia de alta precisión, así como otras de carácter industrial, tales como la implantación iónica en microelectrónica, requieren de dispositivos capaces de conocer la posición de un haz de partículas con alta resolución. El detector de radiación utilizado para determinar la posición de interacción de una partícula o de un haz, en éstas y otras aplicaciones físicas, se denomina hodoscopio, y su función es proporcionar la característica espacial del haz. La tecnología basada en fibra óptica centelleadora es una solución al problema de posicionamiento de alta precisión que ha ido adquiriendo importancia en los ú…

Síndromes rares en psicopatologia: revisió bibliogràfica i anàlisi bibliomètrica

2016

espanolLos denominados «sindromes raros» son aquellos que por su etiologia, casuistica, sintomas peculiares o escasa prevalencia poblacional no suelen ser abordados por la literatura cientifica. El objetivo del presente trabajo ha sido realizar una revision bibliografica y un analisis bibliometrico de las publicaciones cientificas que desde 1970 hasta la actualidad se han llevado a cabo en relacion a cuatro de estos sindromes: sindrome de Capgras, sindrome de Cotard, sindrome de Munchausen y Folie a deux. A partir de la consulta de las bases de datos PsycoDOC, PsycINFO y SCOPUS se presentan los resultados obtenidos sobre las caracteristicas clinicas, la epidemiologia, el curso, la comorbili…

Design exploration of aes accelerators on FPGAS and GPUs

2017

The embedded systems are increasingly becoming a key technological component of all kinds of complex tech-nical systems and an exhaustive analysis of the state of the art of all current performance with respect to architectures, design methodologies, test and applications could be very in-teresting. The Advanced Encryption Standard (AES), based on the well-known algorithm Rijndael, is designed to be easily implemented in hardware and software platforms. General purpose computing on graphics processing unit (GPGPU) is an alternative to recongurable accelerators based on FPGA devices. This paper presents a direct comparison between FPGA and GPU used as accelerators for the AES cipher. The res…

Iridokorneālā leņķa novērtēšana optometrista praksē

2016

Bakalaura darbs ir uzrakstīts latviešu valodā uz 29 lapām. Tas satur 19 attēlus, 7 tabulas un 33 atsauces uz literatūras avotiem. Darba mērķis: novērtēt, cik precīzi optometristu praksē iespējams noteikt iridokorneālā leņķa platumu un kādi faktori var ietekmēt šī leņķa lielumu. Metode: iridokorneālais leņķis (IKL) tika novērtēts ar van Herick metodi, izmantojot spraugas lampu, dažādos apgaismojuma apstākļos un priekšējā segmenta optiskās koherences tomogrāfu (AS-OCT). Rezultāti un secinājumi: lai precīzāk raksturotu IKL, jāpapildina van Herick metodes raksturojošās pakāpes. Apgaismojumam mainoties no mezopiskiem uz fotopiskiem apstākļiem, IKL tiek novērtēts par 1-2 pakāpēm platāks. Dalībnie…

Apgrūtināto teritoriju informācijas sistēmas ieviešana Latvijā

2015

Maģistra darbā „Apgrūtināto teritoriju informācijas sistēmas ieviešana Latvijā” aplūkoti Apgrūtināto teritoriju informācijas sistēmas (turpmāk - ATIS) izveidošanas un ieviešanas Latvijā tiesiskie un praktiskie aspekti, kā arī analizēta nekustamo īpašumu lietošanas tiesību apgrūtinājumu reģistrācijas kārtība pirms un pēc ATIS ieviešanas. Analīzes rezultātā identificēti problēmjautājumi un sniegts piedāvājums to risinājumam. Darbā analizēts normatīvais regulējums, kas reglamentē ATIS darbību. Veicot normatīvā regulējuma un juridiskās prakses analīzi, autore aplūkojusi arī Latvijā ar likumu noteiktos nekustamo īpašumu lietošanas tiesību aprobežojumus.

Ammonoid recovery after the Permian-Triassic mass extinction: a re-exploration of morphological and phylogenetic diversity patterns.

2013

The explosive ammonoid rediversification after the Permian–Triassic mass extinction is now well understood in terms of taxonomic richness and biogeography. Using an updated dataset of Early Triassic ammonoids, we compare morphological disparity and taxonomic richness patterns at the regional and global scales. Disparity evolved similarly at both scales, suggesting a global influence of abiotic factors. Morphological diversification occurred early in the Smithian and a marked contraction of the morphospace took place during the end-Smithian extinction. We confirm that trends in disparity and richness were decoupled during the Griesbachian and Dienerian. Three macroevolutionary processes may …

New exotic beams from the SPIRAL 1 upgrade

2018

Since 2001, the SPIRAL 1 facility has been one of the pioneering facilities in ISOL techniques for reaccelerating radioactive ion beams: the fragmentation of the heavy ion beams of GANIL on graphite targets and subsequent ionization in the Nanogan ECR ion source has permitted to deliver beams of gaseous elements (He, N, O, F, Ne, Ar, Kr) to numerous experiments. Thanks to the CIME cyclotron, energies up to 20 AMeV could be obtained. In 2014, the facility was stopped to undertake a major upgrade, with the aim to extend the production capabilities of SPIRAL 1 to a number of new elements. This upgrade, which is presently under commissioning, consists in the integration of an ECR booster in the…
