Tradurre l'invisibile

2017

Cultura e visibile sono due termini con i quali chi si occupa di design della comunicazione visiva si imbatte continuamente, inciampandoci, girandoci intorno, raccogliendoli e portandoli via con sé, facendoli diventare soggetti più che parole che per nessun motivo possono essere ignorati tanto diventano centrali ed essenziali nel processo progettuale di ogni designer. E tanto accade in ogni fase della costruzione della propria professionalità, ovviamente con una diversa consapevolezza e padronanza delle capacità acquisite, all’inizio durante il percorso di studi, nella struttura della propria formazione, nell’esperienza più matura del progetto, della ricerca, della sperimentazione, nella tr…

Noisy dynamics in long and short Josephson junctions

The study of nonlinear dynamics in long Josephson junctions and the features of a particular kind of junction realized using a graphene layer, are the main topics of this research work. The superconducting state of a Josephson junction is a metastable state, and the switching to the resistive state is directly related to characteristic macroscopic quantities, such as the current the voltage across the junction, and the magnetic field through it. Noise sources can affect the mean lifetime of this superconducting metastable state, so that noise induced effects on the transient dynamics of these systems should be taken into account. The long Josephson junctions are investigated in the sine-Gor…

Normal and Abnormal Tissue Classification in Positron Emission Tomography Oncological Studies

2018

Positron Emission Tomography (PET) imaging is increasingly used in radiotherapy environment as well as for staging and assessing treatment response. The ability to classify PET tissues, as normal versus abnormal tissues, is crucial for medical analysis and interpretation. For this reason, a system for classifying PET area is implemented and validated. The proposed classification is carried out using k-nearest neighbor (KNN) method with the stratified K-Fold Cross-Validation strategy to enhance the classifier reliability. A dataset of eighty oncological patients are collected for system training and validation. For every patient, lesion (abnormal tissue) and background (normal tissue around …

Visualization of Large Terrain Using Non-restricted Quadtree Triangulations

2004

This paper presents a set of new techniques oriented towards the real-time visualization of large terrains. These techniques are mainly focused on semi-regular triangulations of non-restricted quadtree terrain representations. Despite the fact that the paper shows that triangulations based on non-restricted quadtrees are as simple and efficient as those based on restricted quadtrees, the new triangulations avoid discontinuity problems among the boundaries of different patches without the need for tree balancing and extra triangles addition. Another important feature of the proposed triangulation is that it incorporates an efficient method for building triangle strips and triangle fans for t…

TASSINARI / VETTA，信件工廠 / Tassinari/Vetta. The factory of letters

2009

的里雅斯特，一個以憂鬱的方式，將肘部靠在窗戶的門檻上，望著大海，是Tassinari / Vetta工作室的所在地，在那里工作完成了對項目的細緻投入的連貫循環，不斷研究和實驗，與短暫的趨勢相距甚遠，而是堅定地依賴於國家和國際，圖形和印刷傳統。然而在工作室裡，人們繼續偏愛那些已經影響到所有人的真正的痴迷，將其僅僅空間變成一個神話般的信件工廠，每個人都在設計中工作，到執行和設置那些將被選擇並用於各種任務的人。這些是首先構思，然後培養，教育和攜帶，直到它們成熟。這種方式可以幫助他們完成將思想轉化為清晰易讀的艱鉅任務，不僅可以作為聲音的正式表達，還可以作為充滿意義的小容器。 Trieste, the city which in a melancholy way, leaning his elbows upon the threshold of the window, looks at the sea, is the seat of the Tassinari/Vetta Studio, where the work completes a coherent cycle made of meticulous devotion to the project, of continuous research and experimentation, quite distant from the transitory trends, but rather firmly anchored to the national and international, graphic and typogra…

Prediction of lncRNA-Disease Associations from Tripartite Graphs

2021

The discovery of novel lncRNA-disease associations may provide valuable input to the understanding of disease mechanisms at lncRNA level, as well as to the detection of biomarkers for disease diagnosis, treatment, prognosis and prevention. Unfortunately, due to costs and time complexity, the number of possible disease-related lncRNAs verified by traditional biological experiments is very limited. Computational approaches for the prediction of potential disease-lncRNA associations can effectively decrease time and cost of biological experiments. We propose an approach for the prediction of lncRNA-disease associations based on neighborhood analysis performed on a tripartite graph, built upon …

Suspension system performance optimization with discrete design variables

2013

Published version of an article in the journal: Structural and Multidisciplinary Optimization. Also available from the publisher at: http://dx.doi.org/10.1007/s00158-013-0888-7 Suspension systems on commercial vehicles have become an important feature meeting the requirements from costumers and legislation. The performance of the suspension system is often limited by available catalogue components. Additionally the suspension performance is restricted by the travel speed which highly influences the ride comfort. In this article a suspension system for an articulated dump truck is optimized in sense of reducing elapsed time for two specified duty cycles without violating a certain comfort th…

A case study of a precision fertilizer application task generation for wheat based on classified hyperspectral data from UAV combined with farm histo…

2013

Different remote sensing methods for detecting variations in agricultural fields have been studied in last two decades. There are already existing systems for planning and applying e.g. nitrogen fertilizers to the cereal crop fields. However, there are disadvantages such as high costs, adaptability, reliability, resolution aspects and final products dissemination. With an unmanned aerial vehicle (UAV) based airborne methods, data collection can be performed cost-efficiently with desired spatial and temporal resolutions, below clouds and under diverse weather conditions. A new Fabry-Perot interferometer based hyperspectral imaging technology implemented in an UAV has been introduced. In this…

Impacts écologiques des formes d'urbanisation : modélisations urbaines et paysagères

2015

The global increase of urbanization during the past decades have induced a progressive artificialization of natural environments. The building of transport infrastructures and new housings causes a landscape fragmentation in an irreversible way and a strong decrease of the connectivity of ecological habitats. Maintaining the functionality of ecological networks is becoming a major goal of sustainable urban planning policies. With a special focus on urban evolutions in the horizon 2030 in the urban area of Besançon in eastern France (residential development and road traffic evolutions), this thesis aims to assess the potential impact of urban forms on landscape connectivity of animal species…

A Composition Approach to Design of Educational Animations

2017

International audience; The educational effectiveness of conventionally designed animations that portray complex, unfamiliar subject matter in a behaviorally realistic fashion too often falls well short of expectations. Previous research indicates that the veridical dynamic properties of these comprehensive animations make a major contribution to their lack of effectiveness. Due to these dynamics, there is a substantial mismatch between the processing demands these animations impose on learners and the characteristics of the human information processing system. As a result, the quality of the mental models that learners are able to construct is compromised. Interventions intended to improve…
