description: Il progetto, svolto con i bambini di terza elementare di Aurigeno – Ronchni, intende cercare le proprie identità competenti, scoprirle, dichiararle ed in seguito metterle a disposizione dei compagni. Il tutto verrà svolto attraverso la lettura del libro “Nel paese delle pulcette” di Beatrice Alemagna che, grazie alla sua storia, ci darà la possibilità di creare gli interventi. Il percorso intende osservare se la scoperta e la valorizzazione delle proprie identità competenti possa portare un cambiamento all’interno del gruppo classe, modificandone il clima e le relazioni. Allo stesso tempo si verificherà se questo lavoro possa far emergere quei bambini che rimangono invisibili agli occhi degli altri. Grazie ai dati raccolti, quali disegni, registrazioni audio, brevi testi e il diario di bordo, si può osservare come la valorizzazione delle proprie competenze porti ad un clima di classe più sereno e disteso, ad un aumento delle relazioni e una diminuzione dei litigi. Inoltre è stato possibile osservare come anche quei bambini invisibili siano riusciti ad emergere e diventare parte attiva del gruppo classe.

description: The present article focuses on studying the extent to which the nonuniqueness that is inherent in the standard quantum mechanical calculation of arrival/transit time distribution can be exploited to enable an empirical scrutiny of any causal trajectory model such as the Bohmian scheme. For this purpose, we consider the example of spin-1/2 neutral particles corresponding to a wave packet which passes through a spin rotator(SR) that contains constant magnetic field confined within a region - in such a case, the transit time distribution can be measured in terms of the spin distribution of particles emerging from the SR. In particular, we investigate the way one can compare the Bohmian predictions obtained for this example with that using one of the quantum approaches, say, the probability current density based scheme. Here the Bohmian calculational procedure involves a couple of critical subtleties that lead to some specific directions for further studies.

Neural network trained via reinforced learning as control for a battery super-capacitor hybrid energy storage system in electric vehicles
Creators: name: Dueck, Kevin
Publisher: name: University of British Columbia
Year: 2020

description: Electric vehicles (EVs) are becoming a more popular alternative to internal combustion engine vehicles, however a concern among EV manufacturers and customers is the longevity of the EV's energy source, the battery. The battery is a large contributor to the cost of an EV and is susceptible to wear due to charge/discharge cycles and heat. This wear is a main depreciator to the EV's worth. Batteries are considered a low power density energy storage device, however a hybrid energy storage system (HESS) can be formed with an improved power density by interfacing batteries and super-capacitors (SCs). An HESS utilizes the high energy density of batteries and the high power density of SCs; this lowers the wear of the batteries by directing high current transients to the capacitors and lowering the heat generated by the batteries. Proper control is imperative to developing an effective HESS that will extend the life of the batteries. This thesis presents a novel control for a typical EV with a battery size of 24kWh coupled with a minimally sized HESS comprised of a SC bank with a 94.5kJ or 26.3Wh capacity using a neural network (NN) trained by a genetic algorithm. This method uses a NN to find patterns in simulated driving profiles to optimize the SCs' state of charge and SCs' current in a way that reduces the RMS current delivered by the batteries by up to 15% and reduces the peak currents by up to 52.5%. A 15% reduction in battery RMS current correlates to a 28% reduction the thermal energy produced by the battery due to its internal resistance. This reduction in heat reduces wear on the battery and simplifies thermal management strategies for the battery. This thesis will discus the construction of such a control system, the code of the genetic algorithm, parameter selection, and the effectiveness of this solution in controlling an HESS for practical use in consumer EVs.

description: Earthquakes are a complex spatiotemporal phenomenon, the underlying mechanism for which is still not fully understood despite decades of research and analysis. We propose and develop a network approach to earthquake events. In this network, a node represents a spatial location while a link between two nodes represents similar activity patterns in the two different locations. The strength of a link is proportional to the strength of the cross-correlation in activities of two nodes joined by the link. We apply our network approach to a Japanese earthquake catalog spanning the 14-year period 1985-1998. We find strong links representing large correlations between patterns in locations separated by more than 1000 km, corroborating prior observations that earthquake interactions have no characteristic length scale. We find network characteristics not attributable to chance alone, including a large number of network links, high node assortativity, and strong stability over time.

description: In questa ricerca si indagano i punti di vista e le pratiche didattiche degli insegnanti di SE e di SM in merito all’insegnamento della geometria, delimitando l’indagine al periodo che comprende il secondo ciclo della scuola elementare e la prima media. I dati sono stati ottenuti attraverso dei questionari e alcune interviste che hanno permesso di chiarire e approfondire le prime risposte. L’analisi è stata condotta incrociando i risultati per evidenziare aspetti convergenti e divergenti tra le convinzioni dei docenti sia dello stesso ordine scolastico che di ordini scolastici diversi. Dal confronto emergono punti interessanti che possono essere considerati e approfonditi nell’ottica di promuovere un discorso sull’armonizzazione del passaggio tra i due ordini di scuola. Il tema dell’armonizzazione si inserisce in relazione all’adeguamento della legislazione scolastica attualmente in atto per consentire l’applicazione del Concordato Harmos in Ticino.

description: We present an overview of quantum key distribution (QKD), a secure key exchange method based on the quantum laws of physics rather than computational complexity. We also provide an overview of the two most widely used commodity security protocols, IPsec and TLS. Pursuing a key exchange model, we propose how QKD could be integrated into these security applications. For such a QKD integration we propose a support layer that provides a set of common QKD services between the QKD protocol and the security applications

description: Does star formation proceed in the same way in large spirals such as the Milky Way and in smaller chemically younger galaxies? Earlier work suggests a more rapid transformation of H$_2$ into stars in these objects but (1) a doubt remains about the validity of the H$_2$ mass estimates and (2) there is currently no explanation for why star formation should be more efficient. M~33, a local group spiral with a mass $\sim 10$\% and a metallicity half that of the Galaxy, represents a first step towards the metal poor Dwarf Galaxies. We have searched for molecular clouds in the outer disk of M~33 and present here a set of detections of both $^{12}$CO and $^{13}$CO, including the only detections (for both lines) beyond the R$_{25}$ radius in a subsolar metallicity galaxy. The spatial resolution enables mass estimates for the clouds and thus a measure of the $N({\rm H}_2) / I_{\rm CO}$ ratio, which in turn enables a more reliable calculation of the H$_2$ mass. Our estimate for the outer disk of M~33 is $N({\rm H}_2) / I_{\rm CO(1-0)} \sim 5 \times 10^{20} \,{\rm cm^{-2}/(K{\rm \ km \ s^{-1}})}$ with an estimated uncertainty of a factor $\le 2$. While the $^{12/13}$CO line ratios do not provide a reliable measure of $N({\rm H}_2) / I_{\rm CO}$, the values we find are slightly greater than Galactic and corroborate a somewhat higher $N({\rm H}_2) / I_{\rm CO}$ value. Comparing the CO observations with other tracers of the interstellar medium, no reliable means of predicting where CO would be detected was identified. In particular, CO detections were often not directly on local HI or FIR or H$α$ peaks, although generally in regions with FIR emission and high HI column density. The results presented here provide support for the quicker transformation of H$_2$ into stars in M~33 than in large local universe spirals.

description: Considerando diversi approcci didattici in rapporto alla realizzazione di un oggetto di studio nell’ambito dell’educazione alle arti plastiche, questa indagine intende esaminare l’importanza di una contestualizzazione dell’oggetto in una dimensione culturale che ne attribuisce un significato condiviso socialmente e dovrebbe permettere un incremento dell’interesse da parte dell’allievo nella manualità. Tramite una ricerca-azione messa in pratica in due classi distinte, con programmazioni caratterizzate da attività contrastanti sotto il profilo del metodo didattico, ogni classe ha sperimentato un’attività inserita esclusivamente in un discorso legato alla dimensione culturale dell’oggetto e un’altra attività in cui l’oggetto era limitato ad una dimensione didattico-operativa, in cui il gesto era al centro dell’interesse. I dati necessari all’analisi sono stati raccolti attraverso delle osservazioni personali circa l’atteggiamento degli allievi nelle diverse situazioni e tramite un questionario con il quale i ragazzi hanno potuto esprimere le proprie opinioni in maniera più completa. Queste proposte didattiche e gli strumenti di rilevazione sono stati concepiti tenendo conto delle richieste del piano di formazione della scuola media, prendendo in considerazione alcuni aspetti storici ed evolutivi della disciplina, del contesto sociale e dello sviluppo della manualità nei giovani. I risultati ottenuti sembrano sottolineare la necessità di introdurre nelle proposte didattiche anche delle conoscenze relative alla dimensione culturale dell’oggetto di studio, senza comunque dimenticare il ruolo altrettanto fondamentale che riveste l’aspetto pratico-realizzativo.

description: This document presents the results from a large-scale survey that took place in early 2020 under the H2020 RRI2SCALE project (Responsible Research and Innovation Ecosystems at Regional Scale for Intelligent Cities, Transport and Energy, GA. 872526). The aim of the survey was to engage citizens from four selected European regions (Overijssel, Vestland, Kriti, Galicia) in defining and
 discussing their views, concerns, and moral issues about the current and future trajectories of their RTD&I ecosystem.
 Approximately 2.000 citizens per region were interviewed, and the outcomes from the analysis resulted in the identification of challenges in each region associated with: (i) citizens and societal engagement in designing open and inclusive territorial R&I ecosystems; (ii) the factors associated with openness and inclusiveness in Regional Dilemma; and (iii) what are the (unstructured) weak societal signals that need to be taken into consideration during the design of future R&I agendas.

Art crimes : queering the revolution through the work of Pussy Riot and Petr Pavlensky
Creators: name: Deveau, Adrian
Publisher: name: University of British Columbia
Year: 2020

description: With the flick of a match, Petr Pavlensky set fire to the Bank of France in Paris, scorching the façade of the Haussmann exterior while French police tackled the artist to the ground. The performance was more than merely a spectacular action, but a call-to-arms for the mass mobilization of the proletariat for global revolution. The artist group Pussy Riot’s performance at Toronto Pride in 2015 also demanded structural change, as they travelled the parade route on a military tank laden with a dildo-shaped missile demanding the removal of Vladimir Putin from Russian office. Since inception, Pavlensky’s performances are exemplary mobilizations of Pussy Riot’s manifesto entitled “Commit an Art Crime,” the main component to the group’s performative acts. Art Crime becomes art as theory, enacting tactics of queer liberation through the form of the performance itself. In my thesis “Art Crimes: Queering the Revolution through the Work of Pussy Riot and Petr Pavlensky,” I will analyze the concept of art crime as a liberational tactic through three frameworks of bodily performance: public intervention, social terrorism, and queer-femme labour. In the first section, I demonstrate the transformative properties of the art crime in Pussy Riot’s performance at Toronto Pride, as well as the situation of Pussy Riot within the trajectory of Russian art. In section two, I apply the art crime to the performances of Petr Pavlensky, Pussy Riot’s predecessor. Section three of the thesis will nuance the art crime within queer femme labour through witchcraft in The Witches of Pussy Riot clean Manezhka, molding a framework for revolutionary tactics through labour in lived experience.

description: We present detailed optical photometry for 25 Type Ibc supernovae within d\approx150 Mpc obtained with the robotic Palomar 60-inch telescope in 2004-2007. This study represents the first uniform, systematic, and statistical sample of multi-band SNe Ibc light curves available to date. We correct the light curves for host galaxy extinction using a new technique based on the photometric color evolution, namely, we show that the (V-R) color of extinction-corrected SNe Ibc at t\approx10 days after V-band maximum is tightly distributed, (V-R)=0.26+-0.06 mag. Using this technique, we find that SNe Ibc typically suffer from significant host galaxy extinction, E(B-V)\approx0.4 mag. A comparison of the extinction-corrected light curves for SNe Ib and Ic reveals that they are statistically indistinguishable, both in luminosity and decline rate. We report peak absolute magnitudes of M_R=-17.9+-0.9 mag and M_R=-18.3+-0.6 mag for SNe Ib and Ic, respectively. Focusing on the broad-lined SNe Ic, we find that they are more luminous than the normal SNe Ibc sample, M_R=-19.0+-1.1 mag, with a probability of only 1.6% that they are drawn from the same population of explosions. By comparing the peak absolute magnitudes of SNe Ic-BL with those inferred for local engine-driven explosions (GRB-SN 1998bw, XRF-SN 2006aj, and SN2009bb) we find a 25% probability that they are drawn from the SNe Ic-BL population. Finally, we fit analytic models to the light-curves to derive typical Ni-56 masses of M_Ni \approx0.2 and 0.5 M_sun for SNe Ibc and SNe Ic-BL, respectively. With reasonable assumptions for the photospheric velocities, we extract kinetic energy and ejecta mass values of M_ej \approx 2 M_sun and E_K\approx1e+51 erg for SNe Ibc, while for SNe Ic-BL we find higher values, M_ej\approx5 M_sun and E_K\approx1e+52 erg. We discuss the implications for the progenitors of SNe Ibc and their relation to engine-driven explosions [ABRIDGED].

description: The Higgs boson of Standard Model, minimally coupled to the gravitation, is not able to produce the inflation of early Universe if its mass exceeds the threshold value, which is equal to m_H^{min} = 142 GeV in the tree approximation for the scalar potential. Two-loop corrections modify the estimate as m_H^{min} = 150 \pm 3 GeV, so that higher-order corrections of perturbation theory are completely under control, though they are numerically important in respect of experimental searches.

description: We consider the one-dimensional Kardar-Parisi-Zhang (KPZ) equation with half Brownian motion initial condition, studied previously through the weakly asymmetric simple exclusion process. We employ the replica Bethe ansatz and show that the generating function of the exponential moments of the height is expressed as a Fredholm determinant. From this the height distribution and its asymptotics are studied. Furthermore using the replica method we also discuss the multi-point height distribution. We find that some nice properties of the deformed Airy functions play an important role in the analysis.

description: A series of [n]cyclo-2,7-pyrenylenes was synthesized. K-region functionalization of the pyrene moieties led to a confined space within those macrocycles. This confined space is especially pronounced for n=5 and resulted in a host-in-host binding with shape complementary alkaline crown ethers. A multifaceted approach combining computation, spectroscopy, and single-crystal X-ray analysis elucidated the binding. A set of strained aromatic macrocycles based on [n]cyclo-2,7-(4,5,9,10-tetrahydro)pyrenylenes is presented with size-dependent photophysical properties. The K-region of pyrene was functionalized with ethylene glycol groups to decorate the outer rim and thereby confine the space inside the macrocycle. This confined space is especially pronounced for n=5, which leads to an internal binding of up to 8.0×104 m−1 between the ether-decorated [5]cyclo-2,7-pyrenylene and shape-complementary crown ether–cation complexes. Both the ether-decorated [n]cyclo-pyrenylenes as well as one of their host–guest complexes have been structurally characterized by single-crystal X-ray analysis. In combination with computational methods the structural and thermodynamic reasons for the exceptionally strong binding have been elucidated. The presented rim confinement strategy makes cycloparaphenylenes an attractive supramolecular host family with a favorable, size-independent read-out signature and binding capabilities extending beyond fullerene guests

We find that its ground state can be a magnetic vortex with a topologically non-trivial distribution of the sublattice magnetization $\vec{l}$ and planar coreless vortex-like structure for the net magnetization $\vec{M}$. For antiferromagnetic samples in the vortex state, in addition to low-frequency modes, we find high-frequency modes with frequencies over the range of hundreds of gigahertz, including a mode localized in a region of radius $\sim$ 30--40 nm near the vortex core.

description: Ultra-wideband (UWB) è una tecnologia radio che utilizza impulsi di energia della durata di pochi nanosecondi per codificare informazioni o segnali in una banda molto ampia. Attualmente viene utilizzato per l’imaging medicale, Ground Penetrating Radars (GPR), location tracking, smart access e comunicazioni ad alto data rate. L’obiettivo di questo progetto di diploma è quello di realizzare un sistema di tracciamento indoor utilizzando la tecnologia UWB, composto da dispositivi in movimento (tag o beacon) che comunicano con ricevitori posizionati in punti noti (ancore). Per determinare la posizione del tag i dispositivi inviano dei messaggi e tramite la misurazione del tempo di volo del segnale ne determinano la distanza. Il progetto inizia analizzando la tecnologia in evoluzione tutt’oggi, per poi realizzare un modulo compatto in grado di comunicare utilizzando la tecnologia UWB e di agire sia come ancora, sia come tag. Il risultato finale consiste in un sistema di localizzazione composto da cinque dispositivi forniti del modulo UWB DWM1000 del produttore Decawave, che compongono una rete in grado di tracciare il tag con un’accuratezza di circa ±5cm e una precisione di 20cm nel 99.7% delle misurazioni1. I metodi di localizzazione utilizzati sono il Single Side Two Way Ranging (SSTWR) e Double Side Two Way Ranging (DSTWR), entrambi si basano sul Time of Flight (ToF) del segnale e possono utilizzare una banda fino a 1.3GHz. I software sviluppati sono in grado di tracciare il tag in tre dimensioni e ne calcolano le coordinate utilizzando un algoritmo di trilaterazione. La portata massima di comunicazione è pari a 40 metri in condizioni LoS. 1Misurazioni in LoS sul piano Azimuth (Theta) dell’antenna xv

description: Possible magnetic properties are studied in the buckybowl molecules: the sumanene and a part of C_60. The Hubbard model is applied to the systems. We find that the molecular structure determines the magnetism in the sumanene. On the other hand, the edge state is found along the zigzag edge of a part of C_60. Therefore, the novel property, transition from molecular magnetism to the magnetism like in nanographene, is found.

description: We investigate how to estimate from atom-position measurements the relative phase of two Bose-Einstein condensates released from a double-well potential. We demonstrate that the phase estimation sensitivity via the fit of the average density to the interference pattern is fundamentally bounded by shot noise. This bound can be overcome by estimating the phase from the measurement of $\sqrt N$ (or higher) correlation function. The optimal estimation strategy requires the measurement of the $N$-th order correlation function. We also demonstrate that a second estimation method -- based on the detection of the center of mass of the interference pattern -- provides sub shot-noise sensitivity. Yet, the implementation of both protocols might be experimentally challenging.

description: The most recent observational evidence seems to indicate that giant molecular clouds are predominantly gravitationally unbound objects. In this paper we show that this is a natural consequence of a scenario in which cloud-cloud collisions and stellar feedback regulate the internal velocity dispersion of the gas, and so prevent global gravitational forces from becoming dominant. Thus, while the molecular gas is for the most part gravitationally unbound, local regions within the denser parts of the gas (within the clouds) do become bound and are able to form stars. We find that the observations, in terms of distributions of virial parameters and cloud structures, can be well modelled provided that the star formation efficiency in these bound regions is of order 5 - 10 percent. We also find that in this picture the constituent gas of individual molecular clouds changes over relatively short time scales, typically a few Myr.

description: The low-lying excited states of $^{10}$Be and $^{12}$Be are investigated within a no-core Monte Carlo Shell Model (MCSM) framework employing a realistic potential obtained via the Unitary Correlation Operator Method. The excitation energies of the 2$^+_1$ and 2$^+_2$ states and the B(E2;$\,2^+_{1,2}\rightarrow$ 0$^+_{g.s.}$) for $^{10}$Be in the MCSM with a standard treatment of spurious center-of-mass motion show good agreement with experimental data. Some properties of low-lying states of $^{10}$Be are studied in terms of quadrupole moments, E2 transitions and single-particle occupation numbers. The E2 transition probability of $^{10}$C, the mirror nucleus of $^{10}$Be, is also presented with a good agreement to experiment. The triaxial deformation of $^{10}$Be and $^{10}$C is discussed in terms of the B(E2) values. The removal of the spurious center-of-mass motion affects differently on various states: for instance, negligible effects on the 2$^+_1$ and 2$^+_2$ levels of $^{10}$Be, while significant and favorable shift for the 1$^-_1$ level. It is suggested that the description of $^{12}$Be needs a larger model space as well as some other higher excited states of $^{10}$Be, as an indicator that these are dominated by intruder configurations.
A relativistic dissipative hydrodynamic description for systems including particle number changing processes

description: Relativistic dissipative hydrodynamic equations are extended by taking into account particle number changing processes in a gluon system, which expands in one dimension boost-invariantly. Chemical equilibration is treated by a rate equation for the particle number density based on Boltzmann equation and Grad's ansatz for the off-equilibrium particle phase space distribution. We find that not only the particle production, but also the temperature and the momentum spectra of the gluon system, obtained from the hydrodynamic calculations, are sensitive to the rates of particle number changing processes. Comparisons of the hydrodynamic calculations with the transport ones employing the parton cascade BAMPS show the inaccuracy of the rate equation at large shear viscosity to entropy density ratio. To improve the rate equation, the Grad's ansatz has to be modified beyond the second moments in momentum.

Evaluation of factors affecting the performance of vacuums used to control respirable crystalline silica in the British Columbia construction industry
Creators: name: Shafie, Shalinda
Publisher: name: University of British Columbia

description: Workers in the construction industry are known to be at risk of high exposures to respirable crystalline silica (RCS). Local exhaust ventilation (LEV) has been proposed by regulators as a primary method to control RCS exposure to construction workers. However, real-world data on the effectiveness of LEV in controlling RCS exposure is limited with available studies providing varying results. This study looks at the use and performance of vacuums, a common type of LEV available, used in conjunction with different hand tools on real-world constructions sites. A combination of study methods including field sampling, worker survey and simulated tests were used. During the field sampling, information regarding the vacuums, work environment conditions and dust exposure measurements were collected. These data were later used in regressions models to determine the determinants that strongly influenced the performance of the vacuums. The worker surveys provided information on the knowledge and attitude of workers. The simulated tests were used to corroborate information from the field sampling or to test specific scenarios where there is potential secondary dust exposure due to the use of vacuums. The study results show that the age and maintenance of the vacuums had the strongest effect on the airflow of the vacuum. However, while maintaining a sufficient airflow is important to ensure dust capture, the correlation of airflow with respirable dust exposure was weak. Both age and maintenance of the vacuums as well as environmental factors play a large part in determining the respirable dust exposure to the worker. It is recommended that all vacuum users are trained in both basic principles of ventilation as well as the standard operating procedure of the specific vacuum model being used. This is as each vacuum operates differently and may require different maintenance processes.

description: Acoustic surface treatments, such as absorbers and diffusers, are used to control unwanted reflections in rooms. These reflections, when excessive, can create an unpleasant experience for both audiences and performers in any space, not just performance spaces. Existing acoustic absorbers, including Helmholtz resonators, quarter-wave resonators, and panel absorbers, are discussed in this thesis. The most common diffuser, the Quadratic Residue Diffuser (QRD), is also explored in detail. While QRDs are well known for their predictability and ease of design, they suffer from two main drawbacks: size and aesthetics. This thesis explores the use of acoustic metamaterials, specifically coiled space metamaterials, to replace the QRD. These metamaterials seek to address these specific problems with QRD designs while replicating its ability to scatter acoustic waves in a predictable fashion. Two specific coiled space metamaterial designs are discussed in detail, and their responses are compared to that of the QRD to determine whether they can be viable replacements. The results of the comparisons, while unable to replicate the response of the standard QRD exactly, did show modest improvements. More validation must be done before a definitive answer can be given as to whether either of these designs are able to be successful replacements for the QRD

description: Sphere packing problems have a rich history in both mathematics and physics; yet, relatively few analytical analyses of sphere packings exist, and answers to seemingly simple questions are unknown. Here, we present an analytical method for deriving all packings of n spheres in R^3 satisfying minimal rigidity constraints (>= 3 contacts per sphere and >= 3n-6 total contacts). We derive such packings for n <= 10, and provide a preliminary set of maximal contact packings for 10 < n <= 20. The resultant set of packings has some striking features, among them: (i) all minimally rigid packings for n <= 9 have 3n-6 contacts, (ii) non-rigid packings satisfying minimal rigidity constraints arise for n >= 9, (iii) the number of ground states (i.e. packings with the maximal number of contacts) oscillates with respect to n, (iv) for 10 <= n <= 20 there are only a small number of packings with the maximal number of contacts, and for 10 <= n < 13 these are all commensurate with the HCP lattice. The general method presented here may have applications to other related problems in mathematics, such as the Erdos repeated distance problem and Euclidean distance matrix completion problems.
description: The updates that have been made to version II are as follows: (i) some updates to the main text have been made, primarily correcting the number of packings reported in PRL, 103, 118303 and in version I of this paper for n = 9,10. (ii) The supplemental information for the paper has been included

description: Rotationally-split modes can provide valuable information about the internal rotation profile of stars. This has been used for years to infer the internal rotation behavior of the Sun. The present work discusses the potential additional information that rotationally splitting asymmetries may provide when studying the internal rotation profile of stars. We present here some preliminary results of a method, currently under development, which intends: 1) to understand the variation of the rotational splitting asymmetries in terms of physical processes acting on the angular momentum distribution in the stellar interior, and 2) how this information can be used to better constrain the internal rotation profile of the stars. The accomplishment of these two objectives should allow us to better use asteroseismology as a test-bench of the different theories describing the angular momentum distribution and evolution in the stellar interiors.
