TISSBERT: A benchmark for the validation and comparison of NDVI time series reconstruction methods

2018

[EN] This paper introduces the Time Series Simulation for Benchmarking of Reconstruction Techniques (TISSBERT) dataset, intended to provide a benchmark for the validation and comparison of time series reconstruction methods. Such methods are routinely used to estimate vegetation characteristics from optical remotely sensed data, where the presence of clouds decreases the usefulness of the data. As for their validation, these methods have been compared with previously published ones, although with different approaches, which sometimes lead to contradictory results. We designed the TISSBERT dataset to be generic so that it could simulate realistic reference and cloud-contaminated time series …

Análisis Interactivo de Datos: Mapas Autoorganizados

2015

Los fenómenos físicos, así como los procesos industriales, producen volúmenes cada vez más cuantiosos de datos, a menudo de difícil tratamiento. Se hace preceptiva la generación de sistemas y procedimientos que permitan extraer, en una primera etapa visual de análisis, la información subyacente a estos datos, orientando así los cálculos y estudios posteriores que puedan aplicarse. El análisis visual será reforzado si se complementa con elementos interactivos que permitan al usuario dirigirse hacia los focos de su interés. Dentro de las técnicas de visualización de datos para los fines expuestos destacan los Mapas Autoorganizados (también llamados SOM, acrónimo de Self-Organizing Maps), un t…

Mappings of L p -integrable distortion: regularity of the inverse

2016

Let X be an open set in R n and suppose that f : X → R n is a Sobolev homeomorphism. We study the regularity of f −1 under the L p -integrability assumption on the distortion function Kf . First, if X is the unit ball and p > n−1, then the optimal local modulus of continuity of f −1 is attained by a radially symmetric mapping. We show that this is not the case when p 6 n − 1 and n > 3, and answer a question raised by S. Hencl and P. Koskela. Second, we obtain the optimal integrability results for |Df −1 | in terms of the L p -integrability assumptions of Kf . peerReviewed

Mappings of Lp-integrable distortion: regularity of the inverse

2016

Let be an open set in ℝn and suppose that is a Sobolev homeomorphism. We study the regularity of f–1 under the Lp-integrability assumption on the distortion function Kf. First, if is the unit ball and p > n – 1, then the optimal local modulus of continuity of f–1 is attained by a radially symmetric mapping. We show that this is not the case when p ⩽ n – 1 and n ⩾ 3, and answer a question raised by S. Hencl and P. Koskela. Second, we obtain the optimal integrability results for ∣Df–1∣ in terms of the Lp-integrability assumptions of Kf.

Glicerīna transportsistēmas un Hog1 loma raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī

2015

Šī darba mērķis bija izpētīt glicerīna transportsistēmu un Hog1p iespējamo lomu raugu šūnu dzīvotspējas saglabāšanā anhidrobiozes stāvoklī. Lai sasniegtu šo mērķi, izmantoja raugu Saccharomyces cerevisiae BY4741 un tā izogēnos celmus, kuriem trūka viens vai vairāki gēni, kuri ir atbildīgi par glicerīna transportiera Stl1p, glicerīna eksporta kanāla Fps1p un regulatorās Hog1p MAP kināzes ekspresiju raugu šūnās. Darbam bija izvirzīti sekojošie uzdevumi: izpētīt S. cerevisiae BY4741 spējas pāriet anhidrobiozes stāvoklī; novērtēt glicerīna transportsistēmu Stl1p un Fps1p, ka arī Hog1p ietekmi uz raugu šūnu rezistenci pret dehidratāciju; izpētīt raugu spējas pārdzīvot osmotisko stresu un šīs ied…

The genome sequence of Blochmannia floridanus: Comparative analysis of reduced genomes

2003

Bacterial symbioses are widespread among insects, probably being one of the key factors of their evolutionary success. We present the complete genome sequence of Blochmannia floridanus , the primary endosymbiont of carpenter ants. Although these ants feed on a complex diet, this symbiosis very likely has a nutritional basis: Blochmannia is able to supply nitrogen and sulfur compounds to the host while it takes advantage of the host metabolic machinery. Remarkably, these bacteria lack all known genes involved in replication initiation ( dna A, pri A, and rec A). The phylogenetic analysis of a set of conserved protein-coding genes shows that Bl. floridanus is phylogenetically related to Buch…

"Narrazioni selettive" e stereotipi massmediatici: la Sicilia del Commissario Montalbano.

2015

Ogni luogo oggi è sottoposto a una forza detta ‘egemonia della visione’ (Urry 2005, Rakic 2012). A territori unici e irripetibili vanno associandosi nuovi generi di luoghi creati secondo un processo di scelte strategiche attraverso icone virtuali, simboli e messaggi impliciti; si creano ‘patrimoni’ basati su una ricostruzione meccanica, sul culto delle immagini (Baudrillard,1981), sulla standardizzazione dei siti e la riproduzione omologata di cinema e media. Rappresentazioni artificiali (o artificiose) e semplificazioni, però, portano spesso a generalizzazioni, false aspettative, creando quelle che si possono definire ‘narrazioni selettive’ (Sandercook, 2003). Ciò accade specialmente nei p…

Contour map of the top of the regional geothermal reservoir of Sicily (Italy).

2015

An integrated review of existing geological and geophysical data – partly acquired during oil and gas exploration – combined with new data provided by deep geothermal studies of selected key areas, was used for the 3D modeling and mapping of the top of the geothermal reservoir developed at a regional scale in Sicily (Central Mediterranean). The resulting 1:500,000 scale map covers the area of the whole Sicily (about 25,700 km2) and is devoted to represent the main input for both the thermal modeling and the evaluation of geothermal potential at a regional scale. As the map indicates the distribution at depth of a likely target for geothermal drilling, it can be also used as a rough indicato…
