Abstract:
Il saggio ricostruisce l'atteggiamento, le analisi e i giudizi della stampa statunitense di fronte al miracolo economico italiano tra il 1960 e il 1964. Il contributo offre due diversi piani di lettura, fra loro complementari. Da un lato, propone una ricostruzione delle dinamiche del miracolo economico (i fattori della crescita, i settori trainanti, le radici della crisi), filtrate attraverso lo sguardo degli osservatori statunitensi, con l'intento di comprendere quali luci e ombre la stagione del boom contribuě a proiettare sull'immagine complessiva dell'Italia allora diffusa oltreoceano. Dall'altro, intende contribuire a un'analisi dell'opinione pubblica americana negli anni Sessanta, facendone emergere in controluce orientamenti e percezioni, convinzioni e prioritŕ, pregiudizi e paure, anzitutto rispetto al problema della crescita economica e dei modelli di sviluppo nel contesto della Guerra Fredda, ma anche in relazione ad alcune scelte dell'amministrazione Kennedy verso l'alleato europeo e ai processi di modernizzazione in corso nella penisola. La ricerca č basata, oltre che su documentazione del Dipartimento di Stato americano, su quotidiani e periodici statunitensi selezionati in base a diffusione, autorevolezza, orientamento e pubblico di riferimento.

Abstract:
We consider the problem of detecting and quantifying the periodic component of a function given noise-corrupted observations of a limited number of input/output tuples. Our approach is based on Gaussian process regression, which provides a flexible non-parametric framework for modelling periodic data. We introduce a novel decomposition of the covariance function as the sum of periodic and aperiodic kernels. This decomposition allows for the creation of sub-models which capture the periodic nature of the signal and its complement. To quantify the periodicity of the signal, we derive a periodicity ratio which reflects the uncertainty in the fitted sub-models. Although the method can be applied to many kernels, we give a special emphasis to the Matérn family, from the expression of the reproducing kernel Hilbert space inner product to the implementation of the associated periodic kernels in a Gaussian process toolkit. The proposed method is illustrated by considering the detection of periodically expressed genes in thearabidopsisgenome.

Abstract:
In this paper, we analyzed the periodicity of discrete Logistic and Tent sequences with different computational precision in detail. Further, we found that the process of iterations of the Logistic and Tent mapping is composed of transient and periodic stages. Surprisingly, for the different initial iterative values, we first discovered that all periodic stages have the same periodic limit cycles. This phenomenon has seriously affected the security of chaotic cipher. To solve this problem, we designed a novel discrete chaotic sequence generator based on m-sequence and discrete chaotic mapping. The experimental results indicated that the chaotic sequence generator can generate pseudorandom chaotic sequences with large periodicity and good performance under the condition of limited computational precision.

Abstract:
AbstractData from multiple ice and sediment cores in the North Atlantic show that Marine Oxygen Isotope Stage 3 (MIS 3) was characterized by recurring millennial-scale variations in climate, but the periodic behavior of the well-known millennial-scale variations, Heinrich events and Dansgaard–Oeschger events, is uncertain. We use oxygen isotope values from the Greenland Ice Sheet Project 2 (GISP2) and North Greenland Ice Core Project (NGRIP) ice cores and estimated sea-surface temperature derived from a Bermuda Rise marine sediment core as climate proxies to assess the periodic behavior of Heinrich events and Dansgaard–Oeschger events using Lomb–Scargle spectral decomposition and continuous time autoregressive models. We find that continuous time autoregressive models produce less variable estimates of periodicity for Heinrich events than Lomb–Scargle methods. Heinrich events during MIS 3 are periodic with an estimated periodicity of 6.29–6.49 ka in the GISP 2 ice core, 6.71–6.76 ka in the marine sediment core, and 7.89–8.23 ka in the NGRIP core. There is insufficient evidence from these data to conclude that Dansgaard–Oeschger events exhibit a single periodicity during MIS 3. We also find that the periodic behavior of millennial-scale variations depends on the observational time frame.

Abstract:
Computer simulations of electron diffraction patterns and images are an essential step in the process of structure and/or defect elucidation. So far most programs are designed to deal specifically with crystals, requiring frequently the space group as imput parameter. In such programs the deviations from perfect periodicity are dealt with by means of “periodic continuation”.However, for many applications involving amorphous materials, quasiperiodic materials or simply crystals with defects (including finite shape effects) it is convenient to have an algorithm capable of handling non-periodicity. Our program “HeGo” is an implementation of the well known multislice equations in which no periodicity assumption is made whatsoever. The salient features of our implementation are: 1) We made Gaussian fits to the atomic scattering factors for electrons covering the whole periodic table and the ranges [0-2]Å−1 and [2-6]Å−1.

Abstract:
The time-inhomogeneous Feller-type diffusion process, having infinitesimal drift α(t)x+β(t) and infinitesimal variance 2r(t)x, with a zero-flux condition in the zero-state, is considered. This process is obtained as a continuous approximation of a birth-death process with immigration. The transition probability density function and the related conditional moments, with their asymptotic behaviors, are determined. Special attention is paid to the cases in which the intensity functions α(t), β(t), r(t) exhibit some kind of periodicity due to seasonal immigration, regular environmental cycles or random fluctuations. Various numerical computations are performed to illustrate the role played by the periodic functions.

Full text
Abstract:
Periodic adsorption processes have been gaining increasing commercial acceptance as energy efficient alternatives to other separation processes. Such processes are distributed in nature, with properties exhibiting spatial as well as temporal variations. Therefore, they can be mathematically represented by systems of partial differential and algebraic equations (PDAEs).The periodic nature of periodic adsorption processes arises from an externally imposed cyclic variation of the flowrates and intensive properties (e.g. pressure, temperature or composition) of the process feed streams, and of the flowrates of the product streams. This variation leads the system to a "cyclic steady state" (CSS) at which the conditions in each bed at the start and end of each cycle are identical. The traditional approach to cyclic steady state determination has been to carry out a dynamic simulation of the system, starting from a given initial condition, over a large number of cycles. In this work, a novel method is proposed to directly determine a cyclic steady state of periodic adsorption processes by replacing the initial condition specification by a periodicity condition demanding that the system states at the end of each cycle be identical to those at its start. Additional constraints are introduced to characterise the interactions between multiple beds in the process. Detailed dynamic models taking account of the spatial variation of properties within the adsorption bed(s) are used. The resulting systems of partial differential and algebraic equations, and the corresponding boundary conditions, are reduced to sets of algebraic constraints by discretisation with respect to both spatial and temporal dimensions. The performance of periodic adsorption processes is intrinsically affected by various design and operating parameters. The appropriate selection of the values of these parameters may significantly enhances the entire profit of the processes. However, the number of interacting decisions and constraints is such that obtaining an optimal solution by carrying out several dynamic simulations is laborious, if not altogether impossible. A new approach to the optimisation of periodic adsorption processes using mathematical programming is presented. It is demonstrated that the optimal operating and/or design decisions can be determined by solving a single optimisation problem with constraints representing a single bed over a single cycle of operation, irrespective of the number of adsorption beds in the process. Examples of periodic adsorption processes involving different number of adsorption beds and operating cycles are presented to illustrate the approach.

Abstract:
La surveillance de la santé foetale permet aux cliniciens d’évaluer le bien-être du foetus,de faire une détection précoce des anomalies cardiaques foetales et de fournir les traitementsappropriés. Les développements technologies actuels visent à permettre la mesurede l’électrocardiogramme (ECG) foetal de façon non-invasive afin d’extraire non seulementle rythme cardiaque mais également la forme d’onde du signal. Cet objectif est rendudifficile par le faible rapport signal sur bruit des signaux mesurés sur l’abdomen maternel.Cette mesure est donc toujours un challenge auquel se confrontent beaucoup d’études quiproposent des solutions de traitement de signal basées sur la seule modalité ECG.Le but de cette thèse est d’utiliser la modélisation des processus Gaussiens pour améliorerl’extraction des signaux cardiaques foetaux, dans une base multi-modale. L’ECG est utiliséconjointement avec le signal Phonocardiogramme (PCG) qui peut apporter une informationcomplémentaire à l’ECG. Une méthode générale pour la modélisation des signauxquasi-périodiques est présentée avec l’application au débruitage de l’ECG et à l’extractionde l’ECG du foetus. Différents aspects de la multi-modalité (synchronisation, · · · ) proposéesont étudiées afin de détecter avec plus de robustesse les battements cardiaques foetaux.La méthode considère l’application sur les signaux ECG et PCG à travers deux aspects:l’aspect du traitement du signal et l’expérimental. La modélisation des processus Gaussien,avec le signal PCG pris comme la référence, est utilisée pour extraire des modèles flexibleset des estimations non linéaires de l’information. La méthode cherche également à faciliterla mise en oeuvre pratique en utilisant un codage 1-bit des signaux de référence.Le modèle proposé est validé sur des signaux synthétiques et également sur des donnéespréliminaires réelles qui ont été enregistrées afin d’amorcer la constitution d’une base dedonnées multi-modale synchronisée. Les premiers résultats montrent que la méthode permettraà terme aux cliniciens d’étudier les battements cardiaques ainsi que la morphologiede l’ECG. Ce dernier aspect était jusqu’à présent limité à l’analyse d’enregistrements ECGinvasifs prélevés pendant l’accouchement par le biais d’électrodes posées sur le scalp dufoetus
Fetal health must be carefully monitored during pregnancy to detect early fetal cardiac diseases, and provide appropriate treatment. Technological development allows a monitoring during pregnancy using the non-invasive fetal electrocardiogram (ECG). Noninvasive fetal ECG is a method not only to detect fetal heart rate, but also to analyze the morphology of fetal ECG, which is now limited to analysis of the invasive ECG during delivery. However, the noninvasive fetal ECG recorded from the mother's abdomen is contaminated with several noise sources among which the maternal ECG is the most prominent.In the present study, the problem of noninvasive fetal ECG extraction is tackled using multi-modality. Beside ECG signal, this approach benefits from the Phonocardiogram (PCG) signal as another signal modality, which can provide complementary information about the fetal ECG.A general method for quasi-periodic signal analysis and modeling is first described and its application to ECG denoising and fetal ECG extraction is explained. Considering the difficulties caused by the synchronization of the two modalities, the event detection in the quasi-periodic signals is also studied which can be specified to the detection of the R-peaks in the ECG signal.The method considers both clinical and signal processing aspects of the application on ECG and PCG signals. These signals are introduced and their characteristics are explained. Then, using PCG signal as the reference, the Gaussian process modeling is employed to provide the possibility of flexible models as nonlinear estimations. The method also tries to facilitate the practical implementation of the device by using the less possible number of channels and also by using only 1-bit reference signal.The method is tested on synthetic data and also on real data that is recorded to provide a synchronous multi-modal data set.Since a standard agreement for the acquisition of these modalities is not yet taken into much consideration, the factors which influence the signals in recording procedure are introduced and their difficulties and effects are investigated.The results show that the multi-modal approach is efficient in the detection of R-peaks and so in the extraction of fetal heart rate, and it also provides the results about the morphology of fetal ECG

Abstract:
Este trabalho aborda o problema de modelagem de séries de vazões médias mensais visando previsão e geração de séries sintéticas. Destaca-se que a importância da previsão de valores futuros das séries mensais de vazões assim como a geração de séries sintéticas são fundamentais para o planejamento da operação de sistemas hidroelétricos brasileiros. Estas séries possuem um comportamento periódico na média, na variância e na função de autocorrelação e, portanto, considera-se para a série padronizada os modelos autorregressivos periódicos PAR(pm). Em relação a previsão clássica, a análise do erro de previsão e feita em função do horizonte de previsão. Neste estudo, os erros de previsão são calculados, na escala original da série de vazão, em função dos parâmetros dos modelos ajustados e avaliados para horizontes de previsão h variando de 1 a 12 meses. Estes erros são comparados com as estimativas das variâncias das vazões para o mês que está sendo previsto. Em relação à previsão bayesiana, adota-se os modelos Normal, Log-Normal e t-Student nos processos de estimação e, após, é realizado um estudo da perfomance destes modelos usando o erro quadrático médio, erro absoluto médio e erro percentual absoluto médio. Em relação à geração de séries sintéticas de vazões, um modelo multivariado Log-Normal com três parâmetros e um modelo Log-Normal generalizado foram desenvolvidos. As séries geradas são comparadas com as séries históricas reais utilizando o critério de Kullback-Leibler. Como resultado, tem-se uma avaliação da capacidade de previsão, em meses, dos modelos ajustados para cada mês e a escolha do modelo Log-Normal nos procedimentos de análise bayesiana. Além disso, o modelo utilizado para a geração de séries sintéticas de vazões mensais forneceu evidências que o apontam como uma alternativa ao modelo amplamente adotado no setor elétrico brasileiro para geração de séries de vazões
This work addresses the problem of forecasting and generation series monthly average streamflows. It is noteworthy that the importance of forecasting future values of the series of monthly streamflows as well as the generation of synthetic series are fundamental for planning the operation of Brazilian hydroelectric systems. These series have a periodic behavior on average, variance and autocorrelation function and therefore it is considered for standard series periodic autoregressive models PAR(pm). At the forecast classical analysis of the prediction error is made in function of the prediction horizon. In this study, the forecasting errors are calculated in the original scale of the series of streamflow, depending on the model parameters adjusted and evaluated for forecasting horizons h ranging from 1 to 12 months. These errors are compared with estimates of the variances of the streamflows for the month is provided. Regarding the bayesian prediction, we adopt the models Normal, Log-Normal and t-Student in estimation procedures and, then, is a study of the performance of these models using the mean square error, mean absolute error and mean absolute percentage error. In relation to generation, a Log-Normal multivariate model with three parameters and a Log-Normal generalized model were developed and analyzed using the Kullback-Leibler criterion. As a result there has been an assessment of the predictive power, in months, the adjusted models for each month, the choice of the Log-Normal model in the procedures for bayesian analysis and the model used to generate synthetic series of monthly streamflows provided evidence that point as an alternative model adopted in the Brazilian electric sector

Abstract:
The thesis depicted in this report was the subject of my internship at Dior Haute Couture in Paris. I was a member of the supply chain team and I was working on the women shoes product. The aim was to develop the automation of the replenishment of the stores in the world. As a planner for Europe and the United States, I was in strong interaction with the buyers who were following specific stores and who have strong knowledge about the product. The product required a well understanding of the trend of the market and a significant reactivity to cope with the hazards of the of the fashion industry in the luxury world. The purpose to reach was double: first the automation model should reduce time of the planner job to replenish the stores and secondly the application should give more clarity on the goals decided on the market. Along the development, I have always kept in mind the guarantee of the replenishment quality and the simplification of the planner job.The first chapter of this thesis will refer to the start of my investigation to apply a relevant model to my study case: the definition of the project and a state of art of the different methods to supply a store found in the literature. In the second chapter I will explain the choices I did for the automation of replenishment system. The project was very specific to the company and depends a lot on the intrinsic characteristics of the product. As they were luxury products, the goal was to deliver appropriate grid sizes of women shoes to stores to make the best sales as possible with the less level of stock. The project takes also into account the quality issues to face and the approximations of the production planning.By building this model, it appears that the criteria taken on could be used for wider applications. As a consequence, in the last chapter, I will deal with a new way to calculate stock out rate indicators. The global aim was again to clarify the planner job and to enable him to warn the buyer about critical stocks in the stores.

Abstract:
Periodic Adsorption Processes (PAPs) have gained increasing commercial importance asan energy-efficient separation technique over the past two decades. Based on fluid-solidinteractions, these systems never reach steady state. Instead they operate at cyclic steadystate, where the bed conditions at the beginning of the cycle match with those at the endof the cycle. Nevertheless, optimization of these processes remains particularly challenging,because cyclic operation leads to dense Jacobians, whose computation dominatesthe overall cost of the optimization strategy. In order to efficiently handle these Jacobiansduring optimization and reduce the computation time, this work presents newcomposite step trust-region algorithms based on sequential quadratic programming andinterior point methods for the solution of minimization problems with both nonlinearequality and inequality constraints. Instead of forming and factoring the dense constraintJacobian, these algorithms approximate the Jacobian of equality constraints with a specializedquasi-Newton method. Hence, they are well suited to solve optimization problemsrelated to PAPs. In addition to allowing inexactness of the Jacobian and its null-spacerepresentation, the algorithm also provides exact second order information in the formof Hessian-vector products to improve the convergence rate. The resulting approachalso combines automatic differentiation and more sophisticated integration algorithms toevaluate the direct sensitivity and adjoint sensitivity equations. Numerical performance results on small scale PAP problems and CUTEr problems show significant reduction incomputation time. Furthermore, we propose a systematic methodology to design PSA cycles using asuperstructure based approach. The superstructure is rich enough to predict a numberof different PSA operating steps, and their optimal sequence is obtained by solving anoptimal control problem. PSA is a potential technology for pre-combustion CO2 capturebecause of low operating costs and high performance. We utilize the superstructureapproach to synthesize PSA cycles for this purpose which can separate both H2 andCO2 at high purity and operate with a low power consumption of 86 kWh/tonne of CO2captured.

Full text
Abstract:
In this thesis, identification of periodically varying orders of univariate Periodic Autoregressive Moving-Average (PARMA) processes is mainly studied. The identification of the varying orders of PARMA process is carried out by generalizing the well-known Box-Jenkins techniques to a seasonwise manner. The identification of pure periodic moving-average (PMA) and pure periodic autoregressive (PAR) models are considered only. For PARMA model identification, the Periodic Autocorrelation Function (PeACF) and Periodic Partial Autocorrelation Function (PePACF), which play the same role as their ARMA counterparts, are employed. For parameter estimation, which is considered only to refine model identification, the conditional least squares estimation (LSE) method is used which is applicable to PAR models. Estimation becomes very complicated, difficult and may give unsatisfactory results when a moving-average (MA) component exists in the model. On account of overcoming this difficulty, seasons following PMA processes are tried to be modeled as PAR processes with reasonable orders in order to employ LSE. Diagnostic checking, through residuals of the fitted model, is also performed stating its reasons and methods. The last part of the study demonstrates application of identification techniques through analysis of two seasonal hydrologic time series, which consist of average monthly streamflows. For this purpose, computer programs were developed specially for PARMA model identification.

Abstract:
Abstract Functional optical elements based on nano/micro-periodic structures have attracted much attention. Since the fabrication of these dual-periodic structures requires precise control of periodicity, the semiconductor process such as an electron beam lithography has been mainly employed. However, these techniques have problems with expensive and low throughput for industrial applications. Therefore, there remains a need for low cost and high throughput fabrication methods of dual-periodic structures. Then we developed a multi-exposure interference lithography (MEIL) system using rotational Lloyd’s mirror interferometer to overcome these problems. The advantages of interference lithography are a large processing area and low cost. Our developed rotational Lloyd’s mirror setup enables us to a highly precise superposition of multiple interference fringes by multi-exposure. Furthermore, we developed a measurement setup for reflective diffractive elements using a two axial rotating stage and measured the diffraction properties of the fabricated dual-periodic diffraction gratings. In this paper, as a demonstration, we succeeded in the fabrication of high-dispersion diffraction grating with an enhanced diffraction efficiency of the −3rd order light. The fabricated shapes have a periodicity of 1997 nm and 665 nm. Furthermore, it was confirmed that the intensity of the −3rd order light was enhanced by about 10 times compared to the single periodic grating.

Abstract:
Additive Manufacturing (AM) processes are a class of manufacturing processes in which parts are fabricated in a layer-by-layer fashion. The layer-by-layer fabrication method creates layer-to-layer dynamics. Implementing process control that neglects the layer-to-layer dynamics can lead to process instability. While repetitive process controllers which utilize only layer-to-layer feedback are a viable method, their usefulness is limited in that they are not well-suited for tracking non-periodic layer-domain references. However, since the entire reference signal is typically known a priori in AM process fabrications, a predictive control methodology can be useful for controlling fabrications in which the reference signal is non-periodic. In this paper a model predictive control formulation is extended to two-dimensions and utilized for repetitive process control Simulation results comparing open-loop and controlled fabrications for a Laser Metal Deposition process are given.

Abstract:
Abstract Quasicrystals are materials whose structure cannot be understood within classic crystallographic methodology. Quasiperiodic structures have a long-range orientation order but lack transitional periodicity. This non-periodic structure gives quasicrystals a unique range of physical properties including: poor thermal conductivity; excellent crystallographic stability up to their melting point; can be thermally sprayed to display either wear resistant or abradable characteristics; possess excellent release properties (low coefficient of friction); and, they are non-work hardenable. This effort describes parametric conditions utilized to deposit coatings of identical parent metal chemistry but with vastly different end properties.

Abstract:
The United Nations Human Rights Council has a powerful role to play in addressing the worst forms of child labour. Accountability mechanisms such as the Universal Periodic Review (UPR) – which work to support Member States to improve their human rights situation – are therefore widely seen as important opportunities to advocate for change. Ahead of Nepal’s third UPR cycle in 2021, the CLARISSA programme met with eight UN Permanent Missions to present recommendations addressing the exploitation of children within Nepal’s adult entertainment sector. This spotlight story shares the programme’s experience in advocacting within this process. It also highlights their approach of providing decision makers with recommendations to the Government of Nepal that were underpinned by the importance of integrating a participatory, adaptive and child-centred approach.

Abstract:
The French composer Francis Poulenc had a profound admiration and empathy for the writings of the Spanish poet Federico García Lorca. That empathy was rooted in shared aspects of the artistic temperament of the two figures but was also undoubtedly reinforced by Poulenc’s fellow-feeling on a human level. As someone who wrestled with his own homosexuality and who kept his orientation and his relationships apart from his public persona, Poulenc would have felt an instinctive affinity for a figure who endured similar internal conflicts but who, especially in his later life and poetry, was more open about his sexuality. Lorca paid a heavy price for this refusal to dissimulate; his arrest in August 1936 and his assassination the following day, probably by Nationalist militia, was accompanied by taunts from his killers about his sexuality. Everything about the Spanish poet’s life, his artistic affinities, his personal predilections and even the relationship between these and his death made him someone to whom Poulenc would be naturally drawn and whose untimely demise he would feel keenly and might wish to commemorate musically. Starting with the death of both his parents while he was still in his teens, reinforced by the sudden loss in 1930 of an especially close friend, confidante and kindred spirit, and continuing throughout the remainder of his life with the periodic loss of close friends, companions and fellow-artists, Poulenc’s life was marked by a succession of bereavements. Significantly, many of the dedications that head up his compositions are ‘to the memory of’ the individual named. As Poulenc grew older, and the list of those whom he had outlived lengthened inexorably, his natural tendency towards the nostalgic and the elegiac fused with a growing sense of what might be termed a ‘survivor’s anguish’, part of which he sublimated into his musical works. It should therefore come as no surprise that, during the 1940s, and in fulfilment of a desire that he had felt since the poet’s death, he should turn to Lorca for inspiration and, in the process, attempt his own act of homage in two separate works: the Violin Sonata and the ‘Trois Chansons de Federico García Lorca’. This exposition attempts to unfold aspects of the two men’s aesthetic pre-occupations and to show how the parallels uncovered cast reciprocal light upon their respective approaches to the creative process. It also examines the network of enfolded associations, musical and autobiographical, which link Poulenc’s two compositions commemorating Lorca, not only to one another but also to a wider circle of the composer’s works, especially his cycle setting poems of Guillaume Apollinaire: ‘Calligrammes’. Composed a year after the ‘Trois Chansons de Federico García Lorca’, this intricately wrought collection of seven mélodies, which Poulenc saw as the culmination of an intensive phase in his activity in this genre, revisits some of ‘unheard voices’ and ‘unseen shadows’ enfolded in its predecessor. It may be viewed, in part, as an attempt to bring to fuller resolution the veiled but keenly-felt anguish invoked by these paradoxical properties.
