Passerella con struttura in legno Agno
Creators: name: Panciera, Alice
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2020

description: Una nuova passerella con struttura in legno nel comune di Agno sul fiume Vedeggio deve congiungere i due argini del fiume collegando fra di loro anche due campeggi. La passerella è parte integrante di un progetto della pianificazione comunale, perciò il tracciato sia planimetrico sia altimetrico è dato. Il progetto si trova in linea con la pista d’atterraggio dell’aeroporto del paese. Perciò le quote giocano un ruolo molto importante. La quota massima superiore è vincolata dal volo degli aerei mentre la quota minima inferiore dal franco del fiume. Il volume libero della passerella ciclopedonale sarà di 35m di lunghezza, 3.5m di larghezza e 2.9m di altezza.
On the electronic and vibronic behaviour of organic and perovskite photovoltaics
Creators: name: Gallop, Nathaniel
Publisher: name: Imperial College London
Year: 2021

description: Emerging so-called third-generation photovoltaic technologies, in contrast to their predecessors, encompass a broad catalogue of different material systems and present distinct challenges-- such as material softness and energetic disorder-- to their use in photovoltaics. Herein, we attempt to deepen our understanding of two such challenges: the effect of low donor:acceptor energetic offset on the charge dynamics of organic photovoltaic materials incorporating nonfullerene acceptors, and the interaction between the organic and inorganic sublattices of organohalide perovskites. Initially, we address the problem of charge dynamics in low-offset polymer:NFA blends using multiple ultrafast spectroscopic techniques. Here we find that the unique properties of nonfullerene acceptors necessitate modifications to the standard experimental approach in order to yield useful information. By modifying our spectroscopic technique we find that, despite the formation of long-lived so-called 'Charge Transfer states' within the low-offset blend, the net efficiency of charge separation becomes compromised as the donor:acceptor energetic offset approaches zero. This results in an overall decrease in the net yield of free charge for low-offset blends versus high offset blends which ultimately obviates any enhancement of open-circuit voltage brought about through low-offset blends. We then shift our attention to perovskite photovoltaics. Here, we study the interplay between the organic and inorganic sublattices of organohalide perovskites. Using two-dimensional IR spectroscopy, we find that the substitution of as little as 10% of the organic A-site ions with the inorganic cation caesium strongly inhibits the facile rotation of organic cation, likely as a result of both rigidisation and a change in inorganic lattice geometry. This further supports the view that the dynamics of the inorganic sublattice drive the dynamics of the organic sublattice, as well as the interplay between static and dynamic disorder within organohalide perovskites. Additionally, we study the degree to which coupling between the organic and inorganic sublattices of the perovskite influence the electronic properties of the perovskite. To achieve this, we develop and subsequently employ a novel spectroscopic technique, which we term PC/VIPER to observe how the band edge of the perovskite FAPbBr3 change with stimulation of the vibrational modes of the formamidinium cation. Our results point towards a weak coupling of the C=N stretching mode of the cation to the electronic properties of the perovskite and moreover point to hydrogen bonding as the underlying cause of this coupling. We ultimatley find, contrary to popular belief, that organic cations do play a role (albeit a small one) in determining the electronic properties of the FAPbBr3.

description: Using a multiple-scale asymptotic approach, we have derived the complex cubic Ginzburg-Landau equation for amplified and nonlinearly saturated surface plasmon polaritons propagating and diffracting along a metal-dielectric interface. An important feature of our method is that it explicitly accounts for nonlinear terms in the boundary conditions, which are critical for a correct description of nonlinear surface waves. Using our model we have analyzed filamentation and discussed bright and dark spatially localized structures of plasmons.

Understanding mechanisms of exacerbations in early and established chronic obstructive pulmonary disease
Creators: name: Ritchie, Andrew
Publisher: name: Imperial College London
Year: 2020

description: This thesis examines novel aspects of exacerbations and chronic bronchitis spanning across the spectrum of chronic obstructive pulmonary disease (COPD). Both are important to study since they are implicated in the progression, morbidity and mortality of COPD. This thesis presents work from a recently recruited, novel longitudinal patient cohort dedicated to the serial sampling of individuals at risk of developing COPD (10pyh, 30-45yrs). It describes the characteristics of Early COPD in this group and the exacerbation events that they exhibit. This is a new approach to understanding the pathogenesis which underpins COPD development. To date, the majority of COPD studies attempting to examine the concept of Early COPD have included populations with mean ages older than 60 years1 which inform on late “mild disease as opposed to “early disease”.2 The methodology involved using symptom and treatment diary cards to record an increase in cardinal symptoms associated with an AECOPD. Patients were then seen clinically and data was compared to their baseline state. It found that CT changes consistent with Early COPD are more common than obstructive spirometry . It went on to show that exacerbation events in the Early COPD cohort may exhibit modest inflammatory changes but do find corresponding symptomatic and pathophysiological changes. There is evidence that a proportion do not fully recover and further work is required to ascertain the effect of these events on the development of established COPD. Whilst examining the effect of intermittent bronchitis on COPD progression over a 9-year period in participants of the London exacerbation cohort, this study concluded that, the identification of chronic bronchitis through disease burden questionnaires can be objectively validated with sample tracking data. This thesis found that the higher percentage of baseline visits with sputum collected, the faster FEV1 declined. Finally, this thesis presents the effect of retreatment in incompletely recovered AECOPD. This randomized, placebo control trial found no benefit of treatment with ciprofloxacin of exacerbations with persistent respiratory symptoms or a raised CRP (>=8 mg/dl) at 14 days post exacerbation onset. This suggests that non-recovered exacerbations which may lead to hospital readmission potentially need to be targeted with anti-inflammatory therapies and further research is now warranted to investigate exacerbation recovery.

description: A liderança é um conceito que tem sofrido diversas interpretações teóricas ao longo do século XX e no início do século XXI. Neste sentido, existem inúmeras definições de liderança, que justificam a complexidade do conceito e a sua abrangência a múltiplos contextos. Os diferentes tipos de liderança, aplicados ao contexto escolar, de modo geral, e à figura do diretor, de modo particular, têm implicações inegáveis na organização dos recursos humanos, quer na forma como estes se enquadram na instituição quer no modo como o seu compromisso institucional se reflete nas aprendizagens dos alunos.

Live social influences on human spatial attention and action
Creators: name: Dosso, Jill Ashley
Publisher: name: University of British Columbia
Year: 2020

description: One of the major goals of behavioural research is to understand how people attend to and interact with objects. In this thesis, I was interested in placing these interactions in an embedded, interactionist framework. That is, I aimed to study them as they often occur in the real world – as part of naturalistic real-time social encounters. The focus of this thesis was on triadic social interactions involving two individuals (an actor and an observer) and one acted-on object. Within this system, I evaluated attention, spatial coding, gaze, and action towards objects that are located in the near space of an observer. I asked: how do social effects across these behaviours relate to one another? Can a guiding principle be identified that predicts when a behaviour should be socially modified? Across several studies, I find that willingness to look at meaningless content and willingness to reach for real objects are both reduced in the space near real others. But, covert attention, spatial coding of objects, and willingness to look at meaningful content did not change. To reconcile the potential conflict between these findings, I made a novel prediction: that willingness to attend and willingness to signal that one is attending can be and are dissociated in naturalistic social situations. This was directly tested using a task where the to-be-attended target is a person who can or cannot see the subjects’ gaze. The prediction was supported; participants selectively modify their visible gaze but not their concealed attentional state when their eyes can be seen. This thesis argues that when objects are located near live others, behaviour is modified to the extent that it has the potential to communicate. So, reaching and looking are modified in the near space of others not as a result of internal shifts in attention but as a process that regulates the social signals that we are willing to send to others.

Event structure semantics of reversible process calculi
Creators: name: Graversen, Eva
Publisher: name: Imperial College London
Year: 2020

description: In reversible computing a program can undo a set of past actions. This is useful in many areas including debugging, state-space exploration, and modelling naturally reversible systems. Concurrent reversible programs do not necessarily have a defined most recent action, and therefore rely on cause-respecting reversal, where an action can be reversed if it has not caused other actions. For this reason analysing the causal relationships between actions in reversible process calculi is important. One framework used to describe causal relationships is event structures, which are a well-established model of true concurrency. There exist a number of forms of event structures, including prime, asymmetric, bundle, flow, stable, and general event structures. More recently, reversible forms of some these types of event structure have been defined. We formulate corresponding categories as well as functors and in some cases adjunctions between them. We show that products and coproducts exist in many cases. CCSK is a reversible variant of CCS, which uses static reversibility, meaning a process retains the same structure throughout its computation and simply annotates past actions with keys. We use reversible bundle event structures to define denotational semantics of the reversible process calculus CCSK. CCSK is an uncontrolled reversible calculus, meaning there is no control on whether or when an action reverses and a process can therefore do and undo the same action indefinitely. We therefore modify CCSK to control the reversibility with a rollback primitive, which reverses a specific action and all actions caused by it. To define the event structure semantics of rollback, we exploit event structures' capacity for non-causal reversibility. The pi-calculus is a widely used process calculus, which models communications between processes and allows the passing of communication links. Various operational semantics of the pi-calculus have been proposed, which can be classified according to whether transitions are unlabelled (so-called reductions) or labelled. With labelled transitions, we can distinguish early and late semantics. The early version allows a process to receive names it already knows from the environment, while the late semantics do not. All existing reversible versions of the 휋-calculus use reduction or late semantics, despite the early semantics of the (forward-only) 휋-calculus being more widely used than the late. We de ne 휋IH and 휋IK, the rst reversible early 휋-calculi. The new calculi are a reversible form of the internal 휋-calculus, which is a subset of the 휋-calculus where every link sent by an output is private, yielding greater symmetry between inputs and outputs. We also de ne denotational event structure semantics of 휋IK and operational event structure semantics of 휋IH and prove an equivalence between the two.
On the Bogomol'nyi bound in Einstein-Maxwell-dilaton gravity

description: It has been shown that the 4-dimensional Einstein-Maxwell-dilaton theory allows a Bogomol'nyi-type inequality for an arbitrary dilaton coupling constant $α$, and that the bound is saturated if and only if the (asymptotically flat) spacetime admits a nontrivial spinor satisfying the gravitino and the dilatino Killing spinor equations. The present paper revisits this issue and argues that the dilatino equation fails to ensure the dilaton field equation unless the solution is purely electric/magnetic, or the dilaton coupling constant is given by $α=0, \sqrt 3$, corresponding to the Brans-Dicke-Maxwell theory and the Kaluza-Klein reduction of 5-dimensional vacuum gravity, respectively. A systematic classification of the supersymmetric solutions reveals that the solution can be rotating if and only if the solution is dyonic or the coupling constant is given by $α=0, \sqrt 3$. This implies that the theory with $α\ne 0, \sqrt 3$ cannot be embedded into supergravity except for the static truncation. Physical properties of supersymmetric solutions are explored from various points of view.

Creare situazioni problema in aula di educazione musicale
Creators: name: Delgado Rivilla, Marino

Year: 2018

description: Introduzione: La metodologia didattica, che fa capo a questo lavoro di diploma, viene chiamata didattica per situazioni-problema, didattica per problemi, apprendimento basato sui problemi o PBL (acronimo di Problem-Based Learning). Quest’architettura didattica, attraverso la presentazione a gruppi di studenti di problemi reali, complessi e incompleti, favorisce la loro attivazione nella ricerca di informazioni necessarie e, in modo collaborativo, scaturisce discussioni fra loro per risolvere il problema affrontato (Mansolillo, 2012). Metodologia: Nella prima parte del lavoro vi è una parte puramente descrittiva, in cui, attraverso dei testi, articoli e la consultazione di siti internet, viene fatto un approfondimento teorico sul tema del lavoro. In seguito ho presentato la sperimentazione di questa metodologia in aula di educazione musicale per poi confrontare quanto è descritto in letteratura con quanto vissuto in classe. Risultati: I risultati ottenuti tramite la valutazione mi hanno consentito di misurare le abilità degli studenti nel “Contribuire in prima persona alla realizzazione di progetti artistici collettivi”, inoltre ho constatato la capacità di lavorare in modo collaborativo e critico e, per ultimo, attraverso un processo di tipo metacognitivo ho guidato gli allievi alla riflessione sul proprio operato. Conclusione: Con l’elaborazione di questo lavoro di diploma sono emerse alcune implicazioni positive, come per esempio la motivazione all’apprendimento, poiché gli allievi erano entusiasti di partecipare e progressivamente sono stati sempre più coinvolti nella risoluzione del problema della vita reale; l’apprendimento centrato sullo studente, anziché sui contenuti, valorizza e determina un maggior impegno sia nella ricerca di soluzioni che nell’auto-apprendimento; prendere decisioni ragionevoli e ponderate rievoca il senso di responsabilità e fa capire che i problemi della vita reale non sono sempre facili e che la loro risoluzione non porta necessariamente benefici a tutti.

The structure of the jet in Cyg X-1 inferred from orbital modulation of the radio emission
Creators: name: Zdziarski, Andrzej A.
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: We study free-free absorption of radio emission by winds of massive stars. We derive formulae for the optical depth through the wind measured from a point of emission along a jet, taking into account Compton and photoionization heating and Compton, recombination, line and advection cooling. We apply the developed formalism to radio monitoring data for Cyg X-1, which allows us to obtain strong constraints on the structure of its inner jet. With the data at 15 GHz, and taking into account an anisotropy of the stellar wind in Cyg X-1, we estimate the location of the peak of that emission along the jet at about one orbital separation, i.e., $\sim 3\times 10^{12}$ cm. Given a previous determination of the turnover frequency in Cyg X-1, this implies the location of the base of the jet at $\sim 10^3$ gravitational radii. We also obtain corresponding results at 8.3 GHz and 2.25 GHz, which roughly follow the standard conical partially self-absorbed jet model. Furthermore, we find that the level of the orbital modulation depends on the radio flux, with the modulation being substantially stronger when the radio flux is lower. This is explained by the height of the radio emission along the jet decreasing with the decreasing radio flux, as predicted by jet models. Based on the finding of the flux-dependent orbital modulation, we are able to estimate a range of the possible changes of the form of the radio/X-ray correlation in Cyg X-1 due to free-free absorption. We also derive predictions for the orbital modulation and flux attenuation at frequencies beyond the 2.25--15 GHz range.

description: We report a comprehensive Cu $K$-edge RIXS investigation of $\rm La_{2-x}Sr_xCuO_4$ (LSCO) for 0$\leq$x$\leq$0.35, stripe-ordered $\rm La_{1.875}Ba_{0.125}CuO_4$ (LBCO), and $\rm La_{2}Cu_{0.96}Ni_{0.04}O_4$ (LCNO) crystals. The RIXS spectra measured at three high-symmetry momentum transfer (\textbf{q}) positions are compared as a function of doping and for the different dopants. The spectra in the energy range 1-6 eV can be described with three broad peaks, which evolve systematically with increased doping. The most systematic trend was observed for \textbf{q}=($π$, 0) corresponding to the zone boundary. As hole doping increased, the spectral weight transfer from high energies to low energies is nearly linear with \emph{x} at this \textbf{q}. We interpret the peaks as interband transitions in the context of existing band models for this system, assigning them to Zhang-Rice band$\rightarrow$upper Hubbard band, lower-lying band$\rightarrow$upper Hubbard band, and lower-lying band$\rightarrow$Zhang-Rice band transitions. The spectrum of stripe-ordered LBCO was also measured, and found to be identical to the correspondingly doped LSCO, except for a relative enhancement of the near-infrared peak intensity around 1.5-1.7 eV. The temperature dependence of this near-infrared peak in LBCO was more pronounced than for other parts of the spectrum, continuously decreasing in intensity as the temperature was raised from 25 K to 300 K. Finally, we find that 4\% Ni substitution in the Cu site has a similar effect on the spectra as does Sr substitution in the La site.

description: A leitura é um dos requisitos fundamentais para o sucesso educativo e a inclusão de qualquer indivíduo na sua sociedade de referência. O conceito de biblioteca escolar inclusiva veio reforçar a necessidade de estabelecer as condições de acesso à informação de alunos com diversidade funcional. Esta investigação tem como objetivo principal compreender a forma como a biblioteca de uma escola do concelho do Fundão, objeto do nosso estudo, desenvolve atividades que contribuem para a estimulação de competências de leitura em alunos com diversidade funcional. No estudo empírico adotamos uma metodologia qualitativa, com características de estudo de caso, do tipo exploratório, no qual utilizamos como métodos de recolha de dados: a entrevista semiestruturada, a observação direta e a análise documental. Os resultados obtidos na investigação empírica permitem-nos concluir que a biblioteca escolar analisada, não desenvolve especificamente a estimulação de competências de leitura em alunos com diversidade funcional, no contexto da frequência deste espaço educativo, apesar dos bons recursos humanos e materiais de que dispõe. Por outro lado, não existem níveis formais de colaboração entre o coordenador da biblioteca escolar e os professores de Educação Especial, no sentido de serem desenvolvidas atividades de leitura para este público específico. Palavras-chave: leitura, alunos com diversidade funcional, biblioteca escolar.

description: Organometallic complexes have potential applications as the optically active components of organic light emitting diodes (OLEDs) and organic photovoltaics (OPV). Development of more effective complexes may be aided by understanding their excited state properties. Here we discuss two key theoretical approaches to investigate these complexes: first principles atomistic models and effective Hamiltonian models. We review applications of these methods, such as, determining the nature of the emitting state, predicting the fraction of injected charges that form triplet excitations, and explaining the sensitivity of device performance to small changes in the molecular structure of the organometallic complexes.

description: Neste artigo apresentamos uma análise sobre o estudo internacional Trends in International Mathematics and Science Study (TIMSS), para as literacias de ma-temática e ciências, conduzido pela International Association for the Evaluation of Educational Achievement (IEA), tendo em conta os seus objetivos gerais, as tendências de evolução das performances dos alunos e os respetivos dados refe-rentes a Portugal (por regiões da NUTS II). A revisão bibliográfica e documental revela que Portugal tem vindo a melhorar os seus resultados no TIMSS desde 1995. Revelou, ainda, que existem diferenciações relativamente aos resultados por género e dimensões cognitivas (conhecer, aplicar e raciocinar). No TIMSS 2019 a região Centro foi a unidade territorial que obteve o melhor resultado a matemática e a ciências, no 4.º e 8 anos de escolaridade.

description: The number of defects which are generated on crossing a quantum phase transition can be minimized by choosing properly designed time-dependent pulses. In this work we determine what are the ultimate limits of this optimization. We discuss under which conditions the production of defects across the phase transition is vanishing small. Furthermore we show that the minimum time required to enter this regime is $T\sim π/Δ$, where $Δ$ is the minimum spectral gap, unveiling an intimate connection between an optimized unitary dynamics and the intrinsic measure of the Hilbert space for pure states. Surprisingly, the dynamics is non-adiabatic, this result can be understood by assuming a simple two-level dynamics for the many-body system. Finally we classify the possible dynamical regimes in terms of the action $s=TΔ$.

The timescales and consequences of solid-state sintering in volcanic systems
Creators: name: Ryan, Amy Grace
Publisher: name: University of British Columbia
Year: 2020

description: The permeability of rocks controls the movement of fluids and distribution of pore pressure in Earth’s crust. In volcanic systems the eruptive behavior of silicate magmas is governed by the volume and pressure state of magmatic gases. Reductions in permeability can promote explosivity. At the elevated pressure-temperature conditions endemic to volcanic systems, permeable pathways are ephemeral and can be destroyed by densification processes. The prediction of the intensity and timing of explosive eruptions depends on understanding the mechanisms that create and destroy permeable pathways, and their operational timescales. Solid-state sintering is a diffusion-driven process that converts unconsolidated, crystalline aggregates into dense, low-permeability composites. Elevated temperatures and pressures and substantial dwell times facilitate densification and lithification by solid-state sintering. However, solid-state sintering has largely been discounted in volcanic systems because densification timescales were assumed to be long. In this dissertation I show, for the first time, that solid-state sintering occurs in volcanic settings and on timescales short enough to influence volcanic activity. I use the chemistry, mineral contents, physical properties and microstructures of volcanic shear zones exhumed during two dome-building eruptions to show that they were densified and lithified within the volcanic conduit as a result of solid-state sintering. Reconstructions of each of the eruptions indicate sintering occurred on the timescale of magma ascent (months to years). I also use hot pressing experiments conducted at volcanic temperature-pressure conditions to further constrain the timescale of densification by solid-state sintering: the experiments produce dense, low-permeability rocks over periods of hours to days, and reproduce the dominant textures and properties of naturally-sintered volcanic rocks. The experimental dataset is the basis of a quantitative model that predicts the time-dependent evolution of material density as a result of solid-state sintering. Overall, I identify solid-state sintering as a viable, unrecognized mechanism driving rapid permeability loss and material strengthening in volcanic settings. Densification and lithification as a result of solid-state sintering hinder fluid flow and modulate eruptive behavior, including promoting cyclical explosivity. Finally, my work challenges the perception that crystal-rich aggregates in volcanic settings are persistently permeable and weak areas.

description: Jarzynski's equality (JE) allows us to compute free energy differences from distributions of work. In molecular dynamics simulations, the traditional way of constructing work distributions is to perform as many pulling simulations as possible. But reliable work distributions are not always produced in a finite number of simulations. The computational cost of using JE is not less than other commonly used methods such as Thermodynamic Integration and Umbrella Sampling methods. Here we first show a different proof of JE based on the idea of step-wise pulling procedures that is efficient in computing free energies by using JE. The key point in our proof is that the processes of turning-on/off a harmonic potential to perform work are described by double Heaviside functions of time. We then show that the distributions of work performed by the potential can be easily generated from the distributions of a reaction coordinate along a pathway. Based on the proof, we propose sequential and parallel step-wise pulling protocols for generating work distributions that require suitable relaxation time at each pulling step. The criterion for reliable work distributions is that there must be sufficient mutual overlaps between the adjacent distributions of the reaction coordinate along the pathway. We arrive at an alternative formula (besides JE) to compute free energy differences from the averaged values of the reaction coordinate. The combination of JE and the alternative formula provides a viable way to determine the accuracy of computed free energy differences. For the stretching of a deca-alanine molecule, our approach requires 21 parallel simulations and relaxation time as small as 0.4 ns for each simulation to estimate free energy differences with an uncertainty of about 13%.

description: This work is devoted to the study of the process of a mask creating for grounding holes on the back of a GaAs substrate. In the course of the assignment, the work on the installation of MJB4 was mastered. As the results of the work, the conditions of the photolithography process on the back side of the substrate using the FP-4-04mS photoresist were selected, and the quality of the manufactured photoresist mask was analyzed. The paper also presents the results of the test process for etching through holes in a GaAS substrate. The analysis of the results showed that the photoresistive mask formed on the back of the plate was made qualitatively. As the result, the MJB4 installation was mastered and the photolithography process on the back side of the GaAs substrate with the aim of creation photoresist mask for liquid etching of the ground holes was conduct.

description: Dynamical electro-weak symmetry breaking is an appealing, strongly-coupled alternative to the weakly-coupled models based on an elementary scalar field developing a vacuum expectation value. In the first two sections of this set of lectures, I summarize the arguments, based on low-energy phenomenology, supporting walking technicolor as a realistic realization of this idea. This pedagogical introduction to walking technicolor, and more generally to the physics of extensions of the standard model, makes extensive use of effective field theory arguments, symmetries and counting rules. The strongly-coupled nature of the underlying interactions, and the peculiar quasi-conformal behavior of the theory, require to use non-perturbative methods in order to address many fundamental questions within this framework. The recent development of gauge/gravity dualities provides an ideal set of such non-perturbative instruments. The remaining two sections illustrate the potential of these techniques with two technical examples, one within the bottom-up phenomenological approach to holography in five-dimensions, the other within a more systematic top-down construction derived from ten-dimensional type-IIB supergravity.
