Estudio médico-legal de los casos de asesinatos en serie sucedidos en España en los últimos treinta años (1984-2014)
2018
El asesino en serie es visto hoy en día como uno de los grandes depredadores humanos de nuestra sociedad. Constituye un problema y un gran reto para aquellos que se enfrentan a este tipo de violencia, tanto al tratar de atajarla como de prevenirla. Como en cualquier otro tipo de delito, conocer y comprender su génesis, sus motivaciones y los factores que lo integran es trascendental para abordar el problema. España no es ajena a este tipo de violencia. No son pocos los homicidas que han presentado tal clase de patrón en los últimos años. El presente trabajo trata de analizar los casos de asesinatos seriales que se han dado en nuestro país en las tres últimas décadas, entre 1984 y 2014, una …
Every great wine starts in grapevine nursery. Tendencies and perspectives of Sicilian grapevine nurseries
2010
Grapevine nursery production, strictly-regulated by EU norms, represents the important first step in the wine production process, because it’s able to strongly influence both the quali-quantitative performance of farm investments and the type and the quality of wines, with consequences on profitability. The latest reform of the Common Market Organisation (CMO) for wine took effect on August the 1st 2008 and introduced, among many initiatives oriented towards enhancing the competitiveness of the wine sector, a new voluntary three-year grubbing-up scheme from the 2008/2009 season, achieving a balanced wine market, reducing surplus production and providing an alternative for uncompetitive prod…
Expressive character identity of teen lesbian characters on 'Glee' & 'Pretty Little Liars'
2017
Seksuaalivähemmistöjen asema heteronormatiivisessa yhteiskunnassa on puhututtanut ahkerasti muutaman viime vuosikymmenen aikana. Globaalisti seksuaalivähemmistöjä laajalle yleisölle ovat tehneet tutuiksi populaarikulttuuriset valtavirtasisällöt kuten amerikkalaiset elokuvat ja televisiosarjat. Monet nuoret, jotka vasta rakentavat omaa seksuaali-identiteettiään, ammentavat vaikutteita näistä sisällöistä, erityisesti heidän ikäryhmilleen kohdistetuista tuotannoista kuten nuorten sarjoista. Siten on tarpeellista tutkia seksuaalivähemmistöjä edustavien fiktiivisten hahmojen kokonaisvaltaisia representaatioita suosittujen amerikkalaisten nuorten sarjojen kontekstissa ja päivittää tutkimus 1990-l…
Synergy of Sentinel-1 and Sentinel-2 Time Series for Cloud-Free Vegetation Water Content Mapping with Multi-Output Gaussian Processes
2023
Optical Earth Observation is often limited by weather conditions such as cloudiness. Radar sensors have the potential to overcome these limitations, however, due to the complex radar-surface interaction, the retrieving of crop biophysical variables using this technology remains an open challenge. Aiming to simultaneously benefit from the optical domain background and the all-weather imagery provided by radar systems, we propose a data fusion approach focused on the cross-correlation between radar and optical data streams. To do so, we analyzed several multiple-output Gaussian processes (MOGP) models and their ability to fuse efficiently Sentinel-1 (S1) Radar Vegetation Index (RVI) and Senti…
Exploring a large dataset : typical behavior of UHF signal propagation
2020
Radioverkon suunnittelua ja käyttöä varten täytyy radio aaltojen eteneminen ymmärtää hyvin. Tässä tutkimuksessa tutustutaan laajaan mittausaineistoon hetkellisiä tehoja maanlaajuisesta UHF verkosta. Spektrianalyysillä todettiin mitatussa tehossa olevan jaksollista vaihtelua taajuuksilla kerran ja kahdesti päivässä. Myös nopeampaa vaihtelua välillä 0:1 mHz ja 1:4 mHz todettiin 34% yhteyksistä. Hierarkisella ryhmittelyllä etsittiin tyypilliset mittausten arvojakaumat. Saaduissa arvojakaumien ryhmissä oli eri levyisiä vasemmalle tai oikealle vinoja tai symmetrisiä jakaumia. The design and operation of radio networks requires good understanding of radio propagation. This study explores a datase…
Economic policy uncertainty effects for forecasting future real economic activity
2018
Recently introduced measures for Economic Policy Uncertainty (EPU) included in the data from 1997 - 2016 have a role in forecasting out-of-sample values for the future real economic activity for both the euro area and the UK economies. The inclusion of EPU measures, either for the US, the UK or for overall European economies, improves the forecasting ability of models based on standard financial market information, especially for the period before the 2008 global crisis. However, during and after the crisis period, the slope of the yield curve and excess stock market returns improves the out-of-sample forecast performance the most compared to an AR-benchmark model. Hence, the EPU informatio…
Spatial variability of dry spells duration statistical distributions
2014
Dry spells duration and its extent in space, is a key factor in water resources problems. In order to modelling the empirical distribution of dry spells (DS) frequencies observed in Sicily (i.e. in a typical Mediterranean climate), Agnese et al. (2014) successfully applied the two-parameter polylogarithm-series distribution. Because of the strong seasonality characterising Sicily’s rainfall regime, statistical analysis was separately applied to two data sets, referred to as “dry” and “wet” seasons, respectively. In this work, a similar analysis was carried out for a set of 26 DS time-series recorded in a large area (about 30000 km2), including Piedmont and the Aosta Valley. Area altitude ra…
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 …
Multidimensional P-adic Integrals in some Problems of Harmonic Analysis
2017
The paper is a survey of results related to the problem of recovering the coefficients of some classical orthogonal series from their sums by generalized Fourier formulas. The method is based on reducing the coefficient problem to the one of recovering a function from its derivative with respect to an appropriate derivation basis. In the case of the multiple Vilenkin system the problem is solved by using a multidimensional P-adic integral.
Land-use changes in an agro-pastoral area (Djougou, Benin) from Landsat archive images (1984 and 2012): a regressive approach combining remote sensin…
2018
Extended abstract:The vegetation of the district of Djougou is affected by large changes due to tree logging, crop field clearing and grazing by increasing numbers of livestock. The dynamics of the landscape is analyzed with a time series of Landsat satellite images (1984-2012). A regressive approach, exploiting the field observations and semi-structured interviews conducted in 2012-2013 in the Bakou-Wewe territory, documents the evolution of land use and facilitates the analysis of Landsat images. An original procedure targets the building of Region of interest (ROIs) for the historic images for which no available field observations exists. The study area is located in central Benin (Plate…
