Le potenzialità dello haiku all'interno della didattica del testo poetico
Creators: name: Falchetti, Marco

Year: 2023

description: Il presente lavoro di diploma intende verificare, partendo dall’impiego di un genere poetico extravagante quale lo haiku – breve e allo stesso tempo ricco di molti significati, nonché dimostrazione di una tecnica poetica fondata sulla fondamentale quanto impegnativa pratica di sintesi di pensiero –, una possibile variazione dell’apprezzamento del testo poetico tra le mura della scuola dell’obbligo. Per misurare empiricamente l’oscillazione sperata, si è scelto di affrontare, assieme a una classe di terza della scuola media di Castione, un percorso didattico articolato attorno a sei differenti situazioni di apprendimento (due delle quali prevedevano la somministrazione dei questionari, strumenti necessari per quantificare l’indagine pratica). Seguendo alcuni traguardi di competenza indicati dal Piano di studio della scuola dell’obbligo ticinese, il presente percorso è stato incentrato da un lato sulla scoperta delle differenti parti che formano lo haiku, e dall’altro sul diretto engagement degli allievi, i quali, sulle battute finali e sfruttando le potenzialità di una didattica fondata sui principi dell’outdoor learning, si sono occupati di comporre – ognuno secondo la propria irripetibile sensibilità – una serie di haiku, finalmente raccolti all’interno di una piccola antologia poetica. Tale percorso, oltre a garantire lo sviluppo di alcune competenze fondamentali legate al curriculum dell’italiano, ha insistito anche su una serie di competenze trasversali necessarie per un’adeguata crescita emotiva e personale, come ad esempio lo Sviluppo di sé e il Pensiero riflessivo e critico. Al di là della ristretta popolazione di riferimento (motivo per il quale l’esito non può dirsi universale e definitivo), i risultati raccolti dimostrano un chiaro rovesciamento di alcune misconcezioni relative al testo poetico rilevate in entrata, così come una forte spinta d’entusiasmo, da parte della classe, nel provare a misurarsi con la composizione di una poesia breve, enigmatica e profondamente umana.

description: GeoGebra is an interactive geometry, algebra, statistics, and calculus application designed for teaching and learn-ing math, science, and engineering. Its dynamic interface allows its users to accurately and interactively visualize their work, models, and results. GeoGebra employs the synthesis of three key features: modeling, visualization, and programming (MVP). Many studies have shown the positive effects of GeoGebra on the efficiency and effectiveness of learning and teaching topics related to science, technology, engineering, and mathematics. In this study, we dis-cuss how GeoGebra provides an environment for learning that is very interactive and collaborative between the learner and the instructor. We also show how integrating GeoGebra into the learning scheme can help improve the skills and knowledge of school and university students in numerous advanced mathematical courses, such as calcu-lus, mathematical statistics, linear algebra, linear programming, computer-aided design, computer-aided geomet-ric design, analytic and projective geometry, and graphical representation. Therefore, this study shows the effec-tiveness of GeoGebra and its MVP key features in science and engineering, particularly in topics related to mathe-matics. Each key feature of GeoGebra is thoroughly analyzed, and further analyses, along with how GeoGebra can be helpful in different topics, are discussed.

description: The results of diffuse neutron scattering experiment on PbMg1/3Nb2/3O3 single crystal above the Burns temperature are reported. It is shown that the high temperature elastic diffuse component is highly anisotropic in low-symmetry Brillouin zones and this anisotropy can be described using Huang scattering formalism assuming that the scattering originates from mesoscopic lattice deformations due to elastic defects. The qualitative agreement between this model and the experimental data is achieved with simple isotropic defects. It is demonstrated that weak satellite maxima near the Bragg reflections can be interpreted as the finite resolution effect.

description: This work is devoted to numerical simulation of flow in a healthy double-leaf venous valve of the popliteal vein in the equilibrium mode with different leaflet elasticities. It is shown that elasticity has little effect on such characteristics as speed on the symmetry axis, shear stresses on the wall, and also on the length of the recirculation zone. However, the length of the stagnant zone strongly responds to the reduction of the Young's modulus, which allows you to find a match between clinical and calculated data.

description: Comparison theorems are established for the Dirac and Klein--Gordon equations. We suppose that V^{(1)}(r) and V^{(2)}(r) are two real attractive central potentials in d dimensions that support discrete Dirac eigenvalues E^{(1)}_{k_dν} and E^{(2)}_{k_dν}. We prove that if V^{(1)}(r) \leq V^{(2)}(r), then each of the corresponding discrete eigenvalue pairs is ordered E^{(1)}_{k_dν} \leq E^{(2)}_{k_dν}. This result generalizes an earlier more restrictive theorem that required the wave functions to be node free. For the the Klein--Gordon equation, similar reasoning also leads to a comparison theorem provided in this case that the potentials are negative and the eigenvalues are positive.

Multiscale simulation and statistical analysis of nanoparticles size effect on nanofluids effective thermal conductivity
Creators: name: Tahmooressi, Hamed
Publisher: name: University of British Columbia
Year: 2020

description: Recent developments in nanofluids have led to a renewed interest in the nanoparticles effect on the effective thermal conductivity (ETC) of nanofluids. There are three parameters that define the nanoparticles properties: size, shape, and material. The effect of nanoparticle shape is simplified to the nanoparticle’s aspect ratio. Although the experimental data for the effect of nanoparticles aspect ratio and material on ETC are quite consistent, there are still controversial results regarding the effect of the nanoparticles size. Limitations in nano-scale experimental observations would make it even harder to approach into this topic. Thus, researchers have proposed many different macroscopic (continuum-based)/microscopic (molecular scale) numerical schemes as an alternative for experimental investigations. However, these studies are sporadic, meaning that there is not a consistent methodology to investigate the effect of the same type of a nanoparticle property in multiple scales. Here, a multiscale numerical analysis, is implemented to study the effect of nanoparticle properties on the nanofluids thermal conductivity. The multiscale analysis consists of macroscale (Navier-Stokes equation), mesoscale (Lattice Boltzmann method), and microscale (Molecular Dynamics). A Finite Element Method is implemented for the continuum-based method. At the mesoscale, results of a Lattice Boltzmann method (LBM) are taken into further statistical analysis. Using the statistical analysis on LBM results would further improve the acceptability of this method. At the microscale, a Molecular Dynamic simulation is used to investigate the effect of nanoparticles size, aspect ratio, and material on thermal energy conduction. The results demonstrate that the nanofluids thermal conductivity and the nanoparticles volume fraction can be linearly correlated. In addition, increasing the nanoparticles aspect ratio can improve ETC of nanofluids. However, the nanoparticle size is not statistically significant (P-Value > 0.050) to be considered as an influencing parameter when the interfacial phenomena (interfacial thermal resistance, nano-liquid layering, etc.) are not taken into account as they are largely affected by other parameters such as nanoparticles/base fluids material. The pure effect of nanoparticles size is compensated by other parameters such as the distribution regime. This leads to the conclusion that nanoparticles size cannot play an important role in enhancing the thermal properties of nanofluids.

description: We prove that the spectral gap of the Swendsen-Wang process for the Potts model on graphs with bounded degree is bounded from below by some constant times the spectral gap of any single-spin dynamics. This implies rapid mixing of the Swendsen-Wang process for the two-dimensional Potts model at all temperatures above the critical one, as well as rapid mixing at the critical temperature for the Ising model. After this we introduce a modified version of the Swendsen-Wang algorithm for planar graphs and prove rapid mixing for the two-dimensional Potts models at all non-critical temperatures.

description: We present spectroscopic results for all galaxies observed with the Spitzer Infrared Spectrograph (IRS) which also have total infrared fluxes f(ir) measured with the Infrared Astronomical Satellite (IRAS), also using AKARI photometry when available. Infrared luminosities and spectral energy distributions (SEDs) from 8 um to 160 um are compared to polycyclic aromatic hydrocarbon (PAH) emission from starburst galaxies or mid-infrared dust continuum from AGN at rest frame wavelengths ~ 8 um. A total of 301 spectra are analyzed for which IRS and IRAS include the same unresolved source, as measured by the ratio fv(IRAS 25 um)/fv(IRS 25 um). Sources have 0.004 < z < 0.34 and 42.5 < log L(IR) < 46.8 (erg per s) and cover the full range of starburst galaxy and AGN classifications. Individual spectra are provided electronically, but averages and dispersions are presented. We find that log [L(IR)/vLv(7.7 um)] = 0.74 +- 0.18 in starbursts, that log [L(IR)/vLv(7.7 um)] = 0.96 +- 0.26 in composite sources (starburst plus AGN), that log [L(IR)/vLv(7.9 um)] = 0.80 +- 0.25 in AGN with silicate absorption, and log [L(IR)/vLv(7.9 um)] = 0.51 +- 0.21 in AGN with silicate emission. L(IR) for the most luminous absorption and emission AGN are similar and 2.5 times larger than for the most luminous starbursts. AGN have systematically flatter SEDs than starbursts or composites, but their dispersion in SEDs overlaps starbursts. Sources with the strongest far-infrared luminosity from cool dust components are composite sources, indicating that these sources may contain the most obscured starbursts.

description: Several recent studies have considered the implications for astrophysics and cosmology of some possible nonclassical properties of spacetime at the Planck scale. The new effects, such as a Planck-scale-modified energy-momentum (dispersion) relation, are often inferred from the analysis of some quantum versions of Minkowski spacetime, and therefore the relevant estimates depend heavily on the assumption that there could not be significant interplay between Planck-scale and curvature effects. We here scrutinize this assumption, using as guidance a quantum version of de Sitter spacetime with known Inonu-Wigner contraction to a quantum Minkowski spacetime. And we show that, contrary to common (but unsupported) beliefs, the interplay between Planck-scale and curvature effects can be significant. Within our illustrative example, in the Minkowski limit the quantum-geometry deformation parameter is indeed given by the Planck scale, while in the de Sitter picture the parameter of quantization of geometry depends both on the Planck scale and the curvature scalar. For the much-studied case of Planck-scale effects that intervene in the observation of gamma-ray bursts we can estimate the implications of "quantum spacetime curvature" within robust simplifying assumptions. For cosmology at the present stage of the development of the relevant mathematics one cannot go beyond semiheuristic reasoning, and we here propose a candidate approximate description of a quantum FRW geometry, obtained by patching together pieces (with different spacetime curvature) of our quantum de Sitter. This semiheuristic picture, in spite of its limitations, provides rather robust evidence that in the early Universe the interplay between Planck-scale and curvature effects could have been particularly significant.

description: Technology is changing at a blistering pace and is impacting on the way we consider knowledge as a free commodity, along with the ability to apply skills, concepts and understandings. Technology is aiding the way the world is evolving, and its contributions to education are not an exemption. While technology advances will play a crucial part in future teaching-learning approaches, educators will also be challenged by the next higher-education generation, the Alpha Generation. This entrepreneurial generation will embrace the innovation, progressiveness, and advancement with the expectation that one in two Generation Alphas will obtain a university degree. In anticipating the educational challenges and opportunities of the future higher education environment, this research reflected on Generation Alpha as the next cohort of university students, considering their preferred learning styles, perceptions and expectations relating to education. The research employed a theoretical analysis based on the characteristics and traits that distinguishes Generation Alpha, spearheaded by technology advances. The empirical investigation considered three independent studies that were previous conducted by authors from Slovakia, Hungary, Australia, and Turkey to understand the challenges and opportunities pertaining to Generation Alpha. The research identified the influence of social media, social connections, high levels of perceptions and the Generation Alpha's ability to interpret information as strengths to consider in future teaching-learning approaches in the higher education environment. This research concluded with recommendations on how universities could be transformed to ensure a better learning experience for Generation Alpha students, aligned with their characteristics, perceptions and expectations.

description: Commodity trading advisors (CTAs), who mainly trade commodity futures, showed good returns in the 2000s. However, since the 2010's, they have not performed very well. One possible reason of this phenomenon is the emergence of short-term reversal traders (STRTs) who prey on CTAs for profit. In this study, I built an artificial market model by adding a CTA agent (CTAA) and STRT agent (STRTA) to a prior model and investigated whether emerging STRTAs led to a decrease in CTAA revenue to determine whether STRTs prey on CTAs for profit. To the contrary, my results showed that a CTAA and STRTA are more likely to trade and earn more when both exist. Therefore, it is possible that they have a mutually beneficial relationship.

description: We consider the simple random walk on random graphs generated by discrete point processes. This random graph has a random subset of a cubic lattice as the vertices and lines between any consecutive vertices on lines parallel to each coordinate axis as the edges. Under the assumption that discrete point processes are finitely dependent and stationary, we prove that the quenched invariance principle holds, that is, for almost every configuration of a point process, the path distribution of the walk converges weakly to that of a Brownian motion.

Multi-Criteria Assessment of Shape Quality in CAD Systems of the Future

description: Unlike many other works, where authors are usually focused on one or two quality criteria, the current manuscript, which is a generalization of the article [35] published in Russian, offers a multi-criteria approach to the assessment of the shape quality of curves that constitute component parts of the surfaces used for the computer modelling of object shapes in various types of design. Based on the analysis of point particle motion along a curved path, requirements for the quality of functional curves are proposed: a high order of smoothness, a minimum number of curvature extrema, minimization of the maximum value of curvature and its variation rate, minimization of the potential energy of the curve, and aesthetic analysis from the standpoint of the laws of technical aesthetics. The authors do not set themselves the task of giving a simple and precise mathematical definition of such curves. On the contrary, this category can include various curves that meet certain quality criteria, the refinement and addition of which is possible in the near future. Engineering practice shows that quality criteria can change over time, which does not diminish the need to develop multi-criteria methods for assessing the quality of geometric shapes. Technical issues faced during edge rounding in 3D models that affect the quality of industrial design product shape have been reviewed as an example of the imperfection of existing CAD systems.

description: For the past three decades, nanoscience has widely affected many areas in physics, chemistry, and engineering, and has led to numerous fundamental discoveries as well as applications and products. Concurrently, quantum science and technology has developed into a cross-disciplinary research endeavour connecting these same areas and holds a burgeoning commercial promise. Although quantum physics dictates the behaviour of nanoscale objects, quantum coherence, which is central to quantum information, communication and sensing has not played an explicit role in much of nanoscience. This Review describes fundamental principles and practical applications of quantum coherence in nanoscale systems, a research area we call quantum-coherent nanoscience. We structure this manuscript according to specific degrees of freedom that can be quantum-coherently controlled in a given nanoscale system such as charge, spin, mechanical motion, and photons. We review the current state of the art and focus on outstanding challenges and opportunities unlocked by the merging of nanoscience and coherent quantum operations.

Sviluppo di un End Effector riconfigurabile per la presa di tessuti
Creators: name: Marino, Andrea
Publisher: name: Scuola Universitaria della Svizzera Italiana (SUPSI)
Year: 2020

description: Lo svolgimento del seguente progetto di diploma ha permesso lo sviluppo di un End Effector modulare, la cui principale funzione è la manipolazione di tessuti dal peso massimo di 1 kg, ma che potrà essere utilizzato anche in altri settori. Il sistema consiste in una pinza a 3 dita, automaticamente riconfigurabili a seconda dei diversi casi d’uso, dove due dita a scelta sono sempre contrapposte mentre la terza si colloca in posizione di disimpegno. Inoltre, due di esse sono considerate “attive”, in quanto montano un sistema di cinghie al fine di premettere lo scorrimento del tessuto, mentre la terza è “passiva” ed attuata solo per permettere la riconfigurazione. Innanzitutto, si è effettuata una ricerca approfondita nell’ambito degli End Effector per robot, concentrandosi in particolare sugli studi riguardanti la manipolazione di tessuti, analizzando le soluzioni da essi proposte e quelle già presenti sul mercato. In seguito si sono redatte, in accordo con il committente, le specifiche del sistema, contenenti i limiti, le prestazioni e le funzioni dello stesso; mediante il documento precedente si sono ricercate le varianti migliori per ognuna delle funzioni (presa, scorrimento, rilevamento e riconfigurazione), utilizzando il metodo di valutazione della cassa morfologica. Essendo in possesso di tutti i requisiti e di un disegno di concetto del sistema da realizzare, si è proceduto con il dimensionamento e la selezione da catalogo di tutti gli elementi necessari al corretto funzionamento dello stesso, con l’obbiettivo di ottenere una forza di presa di 30 N unitamente ad ingombri contenuti, tra cui: alberi, ingranaggi conici, pulegge, cinghie dentate, attuatori, boccole, cuscinetti. Per tutti gli elementi strutturali dell’End Effector per i quali non si è compiuto un dimensionamento analitico, si è realizzato un modello FEM semplificato del sistema, verificando che i carichi, le deformazioni e le sollecitazioni nelle componenti critiche siano inferiori a quelle ammesse dai materiali utilizzati. Partendo dai modelli CAD tridimensionali, si sono realizzate tutte le tavole dei componenti non standardizzati, complete di tutte le tolleranze, lo stato delle superfici ed i trattamenti termici necessari all’ottenimento del prodotto finale; si sono anche realizzate le tavole dei sottoassiemi e quelle degli assiemi principali. Infine, si è realizzato lo schema di montaggio del sistema, si è effettuata un’analisi della massa complessiva dell’End Effector (pari a circa 2.5 kg) verificando che rientrasse nei limiti prestabiliti, e si è fornita una stima dei costi necessari alla realizzazione, che si attestano intorno ai 4700 CHF.

How the Many Worlds Interpretation brings Common Sense to Paradoxical Quantum Experiments

description: The many worlds interpretation of quantum mechanics (MWI) states that the world we live in is just one among many parallel worlds. It is widely believed that because of this commitment to parallel worlds, the MWI violates common sense. Some go so far as to reject the MWI on this basis. This is despite its myriad of advantages to physics (e.g. consistency with relativity theory, mathematical simplicity, realism, determinism, etc.). Here, we make the case that common sense in fact favors the MWI. We argue that causal explanations are commonsensical only when they are local causal explanations. We present several quantum mechanical experiments that seem to exhibit nonlocal "action at a distance". Under the assumption that only one world exists, these experiments seem immune to local causal explanation. However, we show that the MWI, by taking all worlds together, can provide local causal explanations of the experiments. The MWI therefore restores common sense to physical explanation.

The transition from Quantum Zeno to anti-Zeno effects for a qubit in a cavity by modulating the cavity frequency

description: We propose a strategy to demonstrate the transition from the quantum Zeno effect (QZE) to the anti-Zeno effect (AZE) by modulating the central frequency of the cavity mode. Our results are obtained without using the rotating wave approximation (RWA), and the initial state (a dressed state) is easy to prepare. When the central frequency of the cavity mode is resonant with the qubit energy level spacing, the normalized decay rate of the qubit is lower than 1, which manifests the QZE. However, when the cavity frequency is detuned from resonance, the normalized decay rate becomes larger than 1, which corresponds to the AZE. The change from the QZE to the AZE, by just varying the central frequency of the cavity mode, should allow to distinguish these two different effects. Moreover, we find that in the presence of both qubit's intrinsic bath and the cavity bath, the emergence of the QZE and the AZE behaviors relies not only on the match between the qubit energy level spacing and the central frequency of the cavity mode, but also on the coupling strength between the qubit and the cavity mode.

description: Chiral symmetry breaking of phonons plays an essential role in emergent quantum phenomena owing to its strong coupling to spin degree of freedom. However, direct experimental evidence of the chiral phonon-spin coupling is lacking. In this study, we report a chiral phonon-mediated interlayer exchange interaction in atomically controlled ferromagnetic metal (SrRuO3)-nonmagnetic insulator (SrTiO3) heterostructures. Owing to the unconventional interlayer exchange interaction, we have observed rotation of magnetic moments as a function of nonmagnetic insulating spacer thickness, resulting in a spin spiral state. The chiral phonon-spin coupling is further confirmed by phonon Zeeman effects. The existence of the chiral phonons and their interplay with spins along with our atomic-scale heterostructure approach open a window to unveil the crucial roles of chiral phonons in magnetic materials.

description: Engineering of phonons, i.e., collective lattice vibrations in crystals, is essential for manipulating physical properties of materials such as thermal transport, electron-phonon interaction, confinement of lattice vibration, and optical polarization. Most approaches to phonon-engineering have been largely limited to the high-quality heterostructures of typical semiconductors. Yet, artificial engineering of phonons in a variety of materials with functional properties, such as complex oxides, will yield unprecedented applications of coherent tunable phonons in future quantum acoustic devices. In this study, we demonstrate artificial engineering of phonons in the atomic-scale SrRuO3/SrTiO3 superlattices, wherein tunable phonon modes were observed via confocal Raman spectroscopy. In particular, the coherent superlattices led to the backfolding of acoustic phonon dispersion, resulting in zone-folded acoustic phonons in the THz frequency domain. We could further fine-tune the frequencies from 1 to 2 THz via atomic-scale precision thickness control. In addition, we observed a polar optical phonon originating from the local inversion symmetry breaking in the artificial oxide superlattices, exhibiting emergent functionality. Our approach of atomic-scale heterostructuring of complex oxides will vastly expand material systems for quantum acoustic devices, especially with the viability of functionality integration.

description: Objective: To assess the efficacy and tolerability (side-effects profile), and compliance of the combined contraceptive vaginal ring (CCVR) compared with combined oral hormonal contraceptives (COC). Data sources: The PubMed, Embase, POPLINE, Cochrane Central Register of Controlled Trials (CENTRAL), LILACS, ClinicalTrials.gov, Clinical Trials Registry Platform (ICTRP) and CINAHL databases were searched. Methods of study selection: Electronic databases were searched for randomised clinical trials comparing the CCVR with COC with a duration of at least 3 months between 01 December and 15 December 2015. The primary outcome was efficacy. The secondary outcomes were compliance, absence of withdrawal bleeding, breakthrough bleeding, nausea and headache. Heterogeneity was assessed using I2 statistic and Cochran's Q statistic. Results were expressed as odds ratios (OR) with 95% confidence intervals (CIs) using random-effects models or fixed-effects models depending on the heterogeneity. Results: 4368 records were identified, 2844 of which were removed after duplicates and 1524 records were screened. Of these, 1503 were excluded and 21 full text articles were assessed for eligibility. After removing another 7 articles, 14 records were finally included in the qualitative and quantitative analysis. The results show a trend to higher efficacy for the CCVR in preventing pregnancy (Peto OR: 0.52 [95% CI: 0.26–1.04]) and a significantly lower presence of nausea (Peto OR: 0.66 [95% CI: 0.46–0.93]). More cycles were compliant in the CCVR group (Peto OR: 1.22 [95% CI: 1.12–1.32]) and fewer women reported breakthrough bleeding (Peto OR: 0.68 [95% CI: 0.51–0.91]). Conclusions: Our findings demonstrate that the CCVR is as effective and tolerable as the COC but with a better bleeding profile.

description: This work is devoted to the study of the 220/110 kV power supply system. During the study, the main power equipment was selected. After that, based on the selected equipment, the parameters of the power supply system were calculated. Then, with the help of them, the steady-state operation mode was calculated analytically and using RastrWin software. The next point of work was the calculation of currents and voltages for a two-phase short circuit to earth, on their basis vector diagrams of an asymmetric short circuit were constructed. The final part of the work was an assessment of the dynamic stability of the system in the Dymola software.
