Commercial plant-probiotic microorganisms for sustainable organic tomato production systems

Selected plant-probiotic microorganisms, produced by the company CCS Aosta at a commercial scale, are being tested in the Italian Padana plain in open field conditions for their ability to provide adequate crop nutrition and to ensure durable soil fertility for organic tomato production. In this three-years-long project the QLIF-WP333 research team will investigate the potential of soil probiotics management as a tool to improve the quality of tomato fruits and the sustainability of organic tomato production systems

Design and Implementation of Software Solutions for Satellite Ground Segment, with Application to the ESEO Mission

The work presented in this thesis focuses on the design and implementation of software solutions for the ground segment of satellite missions, with application to the ESEO mission. The ESEO project is currently in Phase D after successfully passing the preliminary and critical design reviews and the launch is foreseen in 2017. Starting from our experience with ALMASat-1 mission, we greatly improved the ground systems for a more complex mission like ESEO. One of the most important improvement is the introduction of a Software Defined Radio with a dedicated software application acting as a transceiver capable of communicating with the on-board transceiver at the registered frequencies and using the defined communication protocol and modulation scheme. It also displays and registers the acquired signal for post-processing tasks. The spacecraft monitoring and control system and the telemetry data visualisation and display tool have been designed keeping in mind the high number of subsystems and payloads and the possibility to re-use the same software for future missions with the minimum effort. The introduction of a connection to a database is essential considering the high number of spacecraft and mission data. This thesis also presents the software solutions designed and implemented for ground stations used by EUMETSAT to operate LEO and GEO weather satellites. The Ground Station Analysis and Reporting tool was developed to allow engineers checking through periodic reports the performance of two ground stations located in Svalbard. The Satellite Passes and Conflicts Engine supports now the schedule of Metop and NOAA satellite passes over Svalbard ground station and it can be used to compute passes and resolve conflicts of multiple satellites over multiple ground stations based on the propagation of the TLEs. Finally, a ground station monitoring and control simulator has been implemented and fully tested for the MTG programme

Hate speech annotation: Analysis of an Italian twitter corpus

The paper describes the development of a corpus from social media built with the aim of representing and analysing hate speech against some minority groups in Italy. The issues related to data collection and annotation are introduced, focusing on the challenges we addressed in designing a multifaceted set of labels where the main features of verbal hate expressions may be modelled. Moreover, an analysis of the disagreement among the annotators is presented in order to carry out a preliminary evaluation of the data set and the scheme.L’articolo descrive un corpus di testi estratti da social media costruito con il principale obiettivo di rappresentare ed analizzare il fenomeno dell’hate speech rivolto contro i migranti in Italia. Vengono introdotti gli aspetti significativi della raccolta ed annotazione dei dati, richiamando l’attenzione sulle sfide affrontate per progettare un insieme di etichette che rifletta le molte sfaccettature necessarie a cogliere e modellare le caratteristiche delle espressioni di odio. Inoltre viene presentata un’analisi del disagreement tra gli annotatori allo scopo di tentare una preliminare valutazione del corpus e dello schema di annotazione stesso
