Development and Testing of Hand Exoskeletons

Development and Testing of Hand Exoskeletons

Matteo Bianchi

Springer Nature Switzerland AG
2021
nidottu
This book describes the development of portable, wearable, and highly customizable hand exoskeletons to aid patients suffering from hand disabilities. It presents an original approach for the design of human hand motion assistance devices that relies on (i) an optimization-based kinematic scaling procedure, which guarantees a significant adaptability to the user’s hands motion, and (ii) a topology optimization-based design methodology, which allowed the design of a lightweight, comfortable device with a high level of performance. The book covers the whole process of hand exoskeleton development, from establishing a new design strategy, to the construction and testing of hand exoskeleton prototypes, using additive manufacturing techniques. As such, it offers timely information to both researchers and engineers developing human motion assistance systems, especially wearable ones.

Interpretative Aspects of Quantum Mechanics

Interpretative Aspects of Quantum Mechanics

Matteo Campanella; David Jou; Maria Stella Mongiovì

Springer Nature Switzerland AG
2020
sidottu
This book presents a selection of Prof. Matteo Campanella’s writings on the interpretative aspects of quantum mechanics and on a possible derivation of Born's rule – one of the key principles of the probabilistic interpretation of quantum mechanics – that is independent of any priori probabilistic interpretation. This topic is of fundamental interest, and as such is currently an active area of research. Starting from a natural method of defining such a state, Campanella found that it can be characterized through a partial density operator, which occurs as a consequence of the formalism and of a number of reasonable assumptions connected with the notion of a state. The book demonstrates that the density operator arises as an orbit invariant that has to be interpreted as probabilistic, and that its quantitative implementation is equivalent to Born's rule. The appendices present various mathematical details, which would have interrupted the continuity of the discussion if they had been included in the main text. For instance, they discuss baricentric coordinates, mapping between Hilbert spaces, tensor products between linear spaces, orbits of vectors of a linear space under the action of its structure group, and the class of Hilbert space as a category.

Making, Breaking and Remaking the Irish Missionary Network

Making, Breaking and Remaking the Irish Missionary Network

Matteo Binasco

Springer Nature Switzerland AG
2020
sidottu
This book reconstructs the efforts that were made to establish a missionary network between the two Irish Colleges of Rome, Ireland, and the West Indies during the seventeenth century. It analyses the process which brought the Irish clergy to establish two dedicated colleges in the epicenter of early modern Catholicism and to develop a series of missionary initiatives in the English islands of the West Indies. During a period of great political change in Ireland, continental Europe and the Atlantic region, the book traces how and through which key figures and institutions this clerical channel was established, while at the same time identifying the main obstacles to its development.

Singularly Perturbed Boundary Value Problems

Singularly Perturbed Boundary Value Problems

Matteo Dalla Riva; Massimo Lanza de Cristoforis; Paolo Musolino

Springer Nature Switzerland AG
2021
sidottu
This book is devoted to the analysis of the basic boundary value problems for the Laplace equation in singularly perturbed domains. The main purpose is to illustrate a method called Functional Analytic Approach, to describe the dependence of the solutions upon a singular perturbation parameter in terms of analytic functions. Here the focus is on domains with small holes and the perturbation parameter is the size of the holes. The book is the first introduction to the topic and covers the theoretical material and its applications to a series of problems that range from simple illustrative examples to more involved research results. The Functional Analytic Approach makes constant use of the integral representation method for the solutions of boundary value problems, of Potential Theory, of the Theory of Analytic Functions both in finite and infinite dimension, and of Nonlinear Functional Analysis.Designed to serve various purposes and readerships, the extensive introductory part spanning Chapters 1–7 can be used as a reference textbook for graduate courses on classical Potential Theory and its applications to boundary value problems. The early chapters also contain results that are rarely presented in the literature and may also, therefore, attract the interest of more expert readers. The exposition moves on to introduce the Functional Analytic Approach. A reader looking for a quick introduction to the method can find simple illustrative examples specifically designed for this purpose. More expert readers will find a comprehensive presentation of the Functional Analytic Approach, which allows a comparison between the approach of the book and the more classical expansion methods of Asymptotic Analysis and offers insights on the specific features of the approach and its applications to linear and nonlinear boundary value problems.

Many-Particle Entanglement, Einstein-Podolsky-Rosen Steering and Bell Correlations in Bose-Einstein Condensates

Many-Particle Entanglement, Einstein-Podolsky-Rosen Steering and Bell Correlations in Bose-Einstein Condensates

Matteo Fadel

Springer Nature Switzerland AG
2021
sidottu
This book presents theoretical methods and experimental results on the study of multipartite quantum correlations in spin-squeezed Bose–Einstein condensates. Nonclassical correlations in many-body system?s are particularly interesting for both fundamental research and practical applications. For their investigation, ultracold atomic ensembles offer an ideal platform, due to their high controllability and long coherence times. In particular, we introduce criteria for detecting and characterizing multipartite entanglement, Einstein–Podolsky–Rosen steering, and Bell correlations. Moreover, we present the experimental observation of such correlations in systems of about 600 atoms.

Mind the European Gap

Mind the European Gap

Matteo Garavoglia

Springer Nature Switzerland AG
2021
nidottu
This book presents a number of specific proposals that, if translated into political reality, could contribute to nurturing a Europeanisation of national public spheres. Having left Brexit behind, intellectuals and policy-makers throughout Europe are now passionately discussing how to move forward the process of European integration. Crucial to this effort is the debate about the Europeanisation of national public spheres: a process that should not harm existing national and local identities but, rather, contribute to their enrichment. This book addresses policy-makers, academics, and forward-thinking citizens alike by providing them with a variety of ideas - and the practical steps needed to translate these into reality across selected European countries - to begin narrowing a dangerous gap between national politics and supranational policy-making.

First Measurement of the Running of the Top Quark Mass

First Measurement of the Running of the Top Quark Mass

Matteo M. Defranchis

Springer Nature Switzerland AG
2022
sidottu
In this thesis, the first measurement of the running of the top quark mass is presented. This is a fundamental quantum effect that had never been studied before. Any deviation from the expected behaviour can be interpreted as a hint of the presence of physics beyond the Standard Model. All relevant aspects of the analysis are extensively described and documented. This thesis also describes a simultaneous measurement of the inclusive top quark-antiquark production cross section and the top quark mass in the simulation. The measured cross section is also used to precisely determine the values of the top quark mass and the strong coupling constant by comparing to state-of-the-art theoretical predictions. All the theoretical and experimental aspects relevant to the results presented in this thesis are discussed in the initial chapters in a concise but complete way, which makes the material accessible to a wider audience.

Deep Learning in Multi-step Prediction of Chaotic Dynamics

Deep Learning in Multi-step Prediction of Chaotic Dynamics

Matteo Sangiorgio; Fabio Dercole; Giorgio Guariso

Springer Nature Switzerland AG
2022
nidottu
The book represents the first attempt to systematically deal with the use of deep neural networks to forecast chaotic time series. Differently from most of the current literature, it implements a multi-step approach, i.e., the forecast of an entire interval of future values. This is relevant for many applications, such as model predictive control, that requires predicting the values for the whole receding horizon. Going progressively from deterministic models with different degrees of complexity and chaoticity to noisy systems and then to real-world cases, the book compares the performances of various neural network architectures (feed-forward and recurrent). It also introduces an innovative and powerful approach for training recurrent structures specific for sequence-to-sequence tasks. The book also presents one of the first attempts in the context of environmental time series forecasting of applying transfer-learning techniques such as domain adaptation.

Data Exploration Using Example-Based Methods

Data Exploration Using Example-Based Methods

Matteo Lissandrini; Davide Mottin; Themis Palpanas; Yannis Velegrakis

Springer International Publishing AG
2018
nidottu
Data usually comes in a plethora of formats and dimensions, rendering the exploration and information extraction processes challenging. Thus, being able to perform exploratory analyses in the data with the intent of having an immediate glimpse on some of the data properties is becoming crucial. Exploratory analyses should be simple enough to avoid complicate declarative languages (such as SQL) and mechanisms, and at the same time retain the flexibility and expressiveness of such languages. Recently, we have witnessed a rediscovery of the so-called example-based methods, in which the user, or the analyst, circumvents query languages by using examples as input. An example is a representative of the intended results, or in other words, an item from the result set. Example-based methods exploit inherent characteristics of the data to infer the results that the user has in mind, but may not able to (easily) express. They can be useful in cases where a user is looking for information in an unfamiliar dataset, when the task is particularly challenging like finding duplicate items, or simply when they are exploring the data. In this book, we present an excursus over the main methods for exploratory analysis, with a particular focus on example-based methods. We show how that different data types require different techniques, and present algorithms that are specifically designed for relational, textual, and graph data. The book presents also the challenges and the new frontiers of machine learning in online settings which recently attracted the attention of the database community. The lecture concludes with a vision for further research and applications in this area.

Discussing the Islamic State on Twitter

Discussing the Islamic State on Twitter

Matteo Colombo; Luigi Curini

Springer International Publishing AG
2022
sidottu
This book explores how ordinary Arab-speaking social media users have reacted to propaganda from the Islamic State, rather than how IS propaganda has targeted ordinary users, thus providing a change in perspective in the literature. The authors provide a comprehensive account of the evolution of the Arabic discourse on IS, encompassing all phases of the Caliphate’s political evolution, from the apogee of the Islamic State in October 2014 to the loss of its unofficial capital of Raqqa in September 2017. Taking into account key events, the book also considers the most recurrent topics for IS and its opponents who engage in the Twitter conversation. The analysis is based on around 29 million tweets written in the Arabic language, representing a random sample of around one-third of all Arabic tweets referring to IS over the 2014-2017 timeframe.

French Missionaries in Acadia/Nova Scotia, 1654-1755

French Missionaries in Acadia/Nova Scotia, 1654-1755

Matteo Binasco

Springer International Publishing AG
2022
sidottu
This book investigates and assesses how and to what extent the French Catholic missionaries carried out their evangelical activity amid the natives of Acadia/Nova Scotia from the mid-seventeenth century until 1755, the year of the Great Deportation of the Acadians. It provides a new understanding of the role played by the French missionaries in the most peripheral and less populated area of Canada during the colonial period. The decision to focus on this period is dictated by the need to investigate how and to which extent the French missionaries sought to carry out their activity within a contested territory which was exposed to the pressures coming out of both French and British imperial interests.

Self-Adjoint Extension Schemes and Modern Applications to Quantum Hamiltonians

Self-Adjoint Extension Schemes and Modern Applications to Quantum Hamiltonians

Matteo Gallone; Alessandro Michelangeli; Sergio Albeverio

Springer International Publishing AG
2023
sidottu
This book introduces and discusses the self-adjoint extension problem for symmetric operators on Hilbert space. It presents the classical von Neumann and Krein–Vishik–Birman extension schemes both in their modern form and from a historical perspective, and provides a detailed analysis of a range of applications beyond the standard pedagogical examples (the latter are indexed in a final appendix for the reader’s convenience).Self-adjointness of operators on Hilbert space representing quantum observables, in particular quantum Hamiltonians, is required to ensure real-valued energy levels, unitary evolution and, more generally, a self-consistent theory. Physical heuristics often produce candidate Hamiltonians that are only symmetric: their extension to suitably larger domains of self-adjointness, when possible, amounts to declaring additional physical states the operator must act on in order to have a consistent physics, and distinct self-adjoint extensions describe different physics.Realising observables self-adjointly is the first fundamental problem of quantum-mechanical modelling.The discussed applications concern models of topical relevance in modern mathematical physics currently receiving new or renewed interest, in particular from the point of view of classifying self-adjoint realisations of certain Hamiltonians and studying their spectral and scattering properties. The analysis also addresses intermediate technical questions such as characterising the corresponding operator closures and adjoints. Applications include hydrogenoid Hamiltonians, Dirac–Coulomb Hamiltonians, models of geometric quantum confinement and transmission on degenerate Riemannian manifolds of Grushin type, and models of few-body quantum particles with zero-range interaction.Graduate students and non-expert readers will benefit from a preliminary mathematical chapter collecting all the necessary pre-requisites on symmetric and self-adjoint operators on Hilbert space (including the spectral theorem), and from a further appendix presenting the emergence from physical principles of the requirement of self-adjointness for observables in quantum mechanics.
