description: We explore the electronic structure and transport properties of a metal on top of a (weakly coupled) two-dimensional topological insulator. Unlike the widely studied junctions between topological non-trivial materials, the systems studied here allow for a unique bandstructure and transport steering. First, states on the topological insulator layer may coexist with the gapless bulk and, second, the edge states on one edge can be selectively switched-off, thereby leading to nearly perfect directional transport of charge and spin even in the zero bias limit. We illustrate these phenomena for Bernal stacked bilayer graphene with Haldane or intrinsic spin-orbit terms and a perpendicular bias voltage. This opens a path for realizing directed transport in materials such as van der Waals heterostructures, monolayer and ultrathin topological insulators.

description: The relation between the theory of entanglement and thermodynamics is very tight: a thermodynamic theory of quantum entanglement, as well as the establishment of rigorous formal connections between the laws of thermodynamics and the phenomenology of entanglement are currently open areas of investigation. In this quest, an interesting problem is embodied by the role played by entanglement in processes of work extraction from a working medium embodied by quantum information carriers. In this work, we experimentally address the question "Is there any intrinsic advantage for work extraction given by the use of an entangled working medium?". By addressing work-extraction protocols based on a mechanism intimately linked to the paradigm of Maxwell's daemon, and implementing suitably designed multi-photon optical interferometers, we demonstrate experimentally the intrinsic advantages for such tasks provided by bipartite and genuine multipartite entanglement. We highlight the unique nature of such tests by comparing their performance to standard tests for the inseparability of multi-photon state resources. Our work contributes strongly to the ongoing efforts in establishing photonic systems as a platform for experiments for information thermodynamics.

Hearing damage in pop/rock musicians: assessment of their rehearsal environmen
Creators: name: Ruano, Luis
Publisher: name: Zenodo
Year: 2015

description: Musicians are one of the population sectors that are in high risk of suffering hearing diseases. As music is sound that generally don’t disturb even at a high volume, the awareness of potential issues derived from being exposed to those high levels is very low. The present thesis is developed considering a pop/rock style. It is aimed to rise the awareness of the problem among musicians of one of the most important music styles as former studies state that 74% of rock musicians suffer hearing loss. Throughout the following sections it will be presented different approaches and solutions that were taken in former studies. As part of this thesis goals and as a starting point in prevention, it will be presented a methodology in order to asses the sound levels to which one is exposed to. In addition measures of a real rehearsing situation were taken. Hearing damage in musicians does not only represents a decrease in their quality of life but also a potential loss of the essential component that they need to do what they probably love.

description: Phase behavior of the Yukawa hard-sphere polydisperse mixture with high degree of polydispersity is studied using high temperature approximation (HTA) and mean spherical approximation (MSA). We have extended and applied the scheme developed to calculate the phase diagrams of polydisperse mixtures described by the truncatable free energy models, i.e., the models with Helmholtz free energy defined by the finite number of the moments of the species distribution function. At high degree of polydispersity, several new features in the topology of the two-phase diagram have been observed: the cloud and shadow curves intersect twice and each of them forms a closed loop of the ellipsoidal-like shape with the liquid and gas branches of the cloud curve almost coinciding. Approaching a certain limiting value of the polydispersity index, the cloud and shadow curves shrink and disappear. Beyond this limiting value, polydispersity induces the appearance of the three-phase equilibrium at lower temperatures. We present and analyze corresponding phase diagrams together with distribution functions of three coexisting phases. In general, good agreement was observed between predictions of the two different theoretical methods, i.e., HTA and MSA. Our results confirm qualitative predictions for the three-phase coexistence obtained earlier within the framework of the van der Waals approach.

A Tale of Three Galaxies: A "Clumpy" View of the Spectroscopically Anomalous Galaxies IRAS F10398+1455, IRAS F21013-0739 and SDSS J0808+3948

description: We investigate the dust properties in three spectroscopically anomalous galaxies (IRAS F10398+1455, IRAS F21013-0739 and SDSS J0808+3948). Their Spitzer/IRS spectra are characterized by a steep ~5-8 micron emission continuum, strong emission bands from polycyclic aromatic hydrocarbon (PAH) molecules, and prominent 10 micron silicate emission. The steep ~5-8 micron continuum and strong PAH emission features suggest the presence of starbursts, while the silicate emission is indicative of significant heating from AGNs. The simultaneous detection of these two observational properties has rarely been reported on galactic scale. We employ the PAHFIT software to estimate their starlight contributions, and the CLUMPY model for the components contributed by the AGN tori. We find that the CLUMPY model is generally successful in explaining the overall dust infrared emission, although it appears to emit too flat at the ~5-8 micron continuum to be consistent with that observed in IRAS F10398+1455 and IRAS F21013-0739. The flat ~5-8 micron continuum calculated from the CLUMPY model could arise from the adopted specific silicate opacity of Ossenkopf et al. (1992) which exceeds that of the Draine & Lee (1984) "astronomical silicate" by a factor up to 2 in the ~5-8 micron wavelength range. Future models with a variety of dust species incorporated in the CLUMPY radiation transfer regime are needed for a thorough understanding of the dust properties of these spectroscopically anomalous galaxies.

Measurement and computational model of the maximum stable gain in acoustic feedback scenarios
Creators: name: Plata Rueda, Ángel
Publisher: name: Zenodo
Year: 2015

description: The behaviour of a sound reinforcement system, such as Public Address (PA) system, can be disturbed by the acoustic feedback phenomenon. In such a system, several microphones and loudspeakers are placed in the same room. When the amplified signal radiated by the loudspeakers goes into the microphones, the system could shows instability. Is then, when it can perceive the phenomenon known as the Larsen effect, or howling effect. The potential of automatic feedback control is the reason of why researches have focused on it during the last years. This research is based on experimental results from acoustics measurements. So, this master thesis proposes a methodology to measure the maximum stable gain (maximum achievable amplification) in a given microphone-loudspeaker-­room scenario just below feedback.
The Milky Way's Hot Gas Kinematics: Signatures in Current and Future OVII Absorption Line Observations

description: Detections of $z \approx$ 0 oxygen absorption and emission lines indicate the Milky Way hosts a hot ($\sim 10^6$ K), low-density plasma extending $\gtrsim$50 kpc into the Mily Way's halo. Current X-ray telescopes cannot resolve the line profiles, but the variation of their strengths on the sky constrains the radial gas distribution. Interpreting the OVII K$α$ absorption line strengths has several complications, including optical depth and line of sight velocity effects. Here, we present model absorption line profiles accounting for both of these effects to show the lines can exhibit asymmetric structures and be broader than the intrinsic Doppler width. The line profiles encode the hot gas rotation curve, the net inflow or outflow of hot gas, and the hot gas angular momentum profile. We show how line of sight velocity effects impact the conversion between equivalent width and the column density, and provide modified curves of growth accounting for these effects. As an example, we analyze the LMC sight line pulsar dispersion measure and OVII equivalent width to show the average gas metallicity is $\gtrsim 0.6 Z_{\odot}$ and $b$ $\gtrsim$ 100 km s$^{-1}$. Determining these properties offers valuable insights into the dynamical state of the Milky Way's hot gas, and improves the line strength interpretation. We discuss future strategies to observe these effects with an instrument that has a spectral resolution of about 3000, a goal that is technically possible today.

description: A novel transmission protocol is conceived for a multi-user, multi-relay, multiple-input--multiple-output orthogonal frequency-division multiple-access (MIMO-OFDMA) cellular network based on joint transmit and receive beamforming. More specifically, the network's MIMO channels are mathematically decomposed into several effective multiple-input--single-output (MISO) channels, which are spatially multiplexed for transmission. For the sake of improving the attainable capacity, these MISO channels are grouped using a pair of novel grouping algorithms, which are then evaluated in terms of their performance versus complexity trade-off\footnote{This paper concisely focuses on the transmission protocol proposed in our previous work [1].

Study of Daily Noise Exposure to Avoid Hearing Loss in Musicians
Creators: name: Expósito Pérez, Miquel
Publisher: name: Zenodo
Year: 2015

description: Excessive noise exposure damages hearing and affects directly to quality of life, but it is something that people usually don’t take too much into account. Sometimes this noise is too high and short and you can’t avoid it, but other times, this noise is softer (but dangerous too) and people assume that exposure without knowing that it will damage their hearing system and produce noise-induced hearing loss (NIHL). This second profile is much related with musicians hearing problems, because musicians are exposed in orchestras and other ensembles to excessive sound pressure level and their hearing is being damaged without their knowledge until they notice they listen much worse. In this project, 10 musicians have been measured while they were practicing and playing their instruments to analyse the noise levels each instrument produces. Some questionnaires have been filled for other musicians to analyse their daily activities and if those activities will aggravate their hearing loss risk. It has been computed that musicians are really in risk of NIHL and if they would like to avoid it without any protection, they should play very short periods of time every day (for example, violinists should be exposed only 72 minutes, saxophonists 30 minutes and flutists just 35 seconds).

The study is summarised through the following insights based on the main research questions asked: RQ1. What are the key mechanisms and characteristics of Open Schooling and the project that make the young students prepared for life in 21st century? This research question looks at how secondary schools can change to become agents of change in the local community, including the wider benefits of open schooling models could bring for the community. RQ2. How can school help the students to develop their agency using OS methods in community-change mission’s implementation? This research question looks at internal and external changes needed to be implemented at school level so that implementation of approaches such as open science schooling could sustainably thrive through integration in the school curricula. RQ3. What are the most important knowledge shortages in the field of making various forms of open schooling that drive student agency, such as Schools as Drivers of Change, a reality? This research question looks at the areas that need further investigations and analysis, as uncovered during the implementation of the Schools as Drivers of Change activities.

Western classical composer identification using symbolic data
Creators: name: Capó Clar, Francesc
Publisher: name: Zenodo
Year: 2015

description: In this thesis, we address the problem of automatic composer identification using information from score-like representations. This task calls for computing features that capture both specificities of the common practice in each composer’s period plus individual specificities with regard to notes, chords, durations, etc. Our goal is to find which are the singular characteristics of each composer and therefore be able to identify them. This information can be useful for musicians as well, in order to study which are the common characteristics between composers and their relationship to the historical period. The particularity of this study is related to the large number of composers used in it (106 composers) and the large of works used as well (9876 works). With a view to achieve this, we have designed features based on music theory, in order to extract music properties from the scores. We have performed classification experiments using the information from these features using Random Forest and SVM classifiers. Using the classification results from theses experiments, we have used feature selection in order to achieve better accuracies combining information from different music concepts. Using the best combinations, we have achieved accuracies up to 46,7% (17 composers), 39,0% (47 composers) and 27,6% (106 composers). In addition, we present confusion matrices of the classifications and scalability graphs in terms of accuracy of our approach, fixing the number of composers and the number of works as well. Finally, we analyse the results and we propose further work related to the extension of this study, changing parameters of the features.

description: Ices play a critical role during the evolution of interstellar clouds. Their presence is ubiquitous in the dense molecular medium and their impact is not only limited to chemistry. Species adsorbed onto dust grains also affect cloud thermodynamics. It all depends on the interstellar conditions, the chemical parameters, and the composition of ice layers. In this work, I study the formation of ices by focusing on the interplay between gas and solid phase to determine their role on cloud evolution and star formation. I show that while the formation of ices greatly impacts the cloud chemistry, their role on the thermodynamics is more conservative, and their influence on star formation is only marginal.

description: Strong gate control of proximity-induced spin-orbit coupling was recently predicted in bilayer graphene/transition metal dichalcogenide (BLG/TMDC) heterostructures, as charge carriers can easily be shifted between the two graphene layers, and only one of them is in close contact to the TMDC. The presence of spin-orbit coupling can be probed by weak antilocalization (WAL) in low-field magnetotransport measurements. When the spin-orbit splitting in such a heterostructure increases with the out-of-plane electric displacement field D, one intuitively expects a concomitant increase of WAL visibility. Our experiments show that this is not the case. Instead, we observe a maximum of WAL visibility around D=0. This counterintuitive behavior originates in the intricate dependence of WAL in graphene on symmetric and antisymmetric spin lifetimes, caused by the valley-Zeeman and Rashba terms, respectively. Our observations are confirmed by calculating spin precession and spin lifetimes from an 8x8 model Hamiltonian of BLG/TMDC.

description: The Ophiuchus stellar stream presents a dynamical puzzle: its old stellar populations ($\sim 12$ Gyr) cannot be reconciled with (1) its orbit in a simple model for the Milky Way potential and (2) its short angular extent, both of which imply that the observed stream formed within the last $<1$ Gyr. Recent theoretical work has shown that streams on chaotic orbits may abruptly fan out near their apparent ends; stars in these fans are dispersed in both position and velocity and may be difficult to associate with the stream. Here we present the first evidence of such stream-fanning in the Ophiuchus stream, traced by four blue horizontal branch (BHB) stars beyond the apparent end of the stream. These stars stand out from the background by their high velocities ($v_{\rm los} > 230$ km s$^{-1}$) against $\sim 40$ other stars: their velocities are comparable to those of the stream, but would be exceptional if they were unrelated halo stars. Their positions and velocities are, however, inconsistent with simple extrapolation of the observed cold, high-density portion of the stream. These observations suggest that stream-fanning may be a real, observable effect and, therefore, that Ophiuchus may be on a chaotic orbit. They also show that the Ophiuchus stream is more extended and hence dynamically older than previously thought, easing the stellar population vs. dynamical age tension.

Dual Stellar Halos in the Standard Elliptical Galaxy M105 and Formation of Massive Early-Type Galaxies

Year: 2016
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: M105 is a standard elliptical galaxy, located in the Leo I Group. We present photometry of the resolved stars in its inner region at R ~ 4' ~ 4Reff, obtained from F606W and F814W images in the Hubble Space Telescope archive. We combine this with photometry of the outer region at R ~ 12' ~ 12Reff from archival imaging data. Color-magnitude diagrams of the resolved stars in the inner region show a prominent red giant branch (RGB) with a large color range, while those of the outer region show better a narrow blue RGB. The metallicity distribution function (MDF) of the RGB stars shows the existence of two distinct subpopulations: a dominant metal-rich population (with a peak at [M/H] ~ 0.0) and a much weaker metal-poor population (with a peak at [M/H] ~ -1.1). The radial number density profiles of the metal-rich and metal-poor RGB stars are fit well by a Sersic law with n=2.75+-0.10 and n=6.89+-0.94, and by a single power law, respectively. The MDFs of the inner and outer regions can be described well by accretion gas models of chemical evolution with two components. These provide strong evidence that there are two distinct stellar halos in this galaxy, metal-poor and red metal-rich halos, consistent with the results based on globular cluster systems in bright early-type galaxies (Park & Lee 2013). We discuss the implications of these results with regard to the formation of massive early-type galaxies in the dual halo mode formation scenario.

Addressing user satisfaction in melody extraction

description: The aim of this master thesis is to carry out a perceptual evaluation of the melody extraction task. To do so, it has been conducted a survey in which 26 subjects have participated in order to test some hypotheses about how the different errors affect the perception of the melodies by the users. In view of the results it can be checked how different kind of errors have a different impact in the quality perceived by the users, in such a way that the result of the perceptual evaluation need not to be equal to the one achieved by the current evaluation metrics. Finally, this research shows that there is much scope for future work refining new evaluation metrics to better capture user preferences.

description: We report on an extensive study of the evolution of domain wall networks in Friedmann-Lema\^ıtre-Robertson-Walker universes by means of the largest currently available field-theory simulations. These simulations were done in $4096^3$ boxes and for a range of different fixed expansion rates, as well as for the transition between the radiation and matter eras. A detailed comparison with the velocity-dependent one-scale (VOS) model shows that this cannot accurately reproduce the results of the entire range of simulated regimes if one assumes that the phenomenological energy loss and momentum parameters are constants. We therefore discuss how a more accurate modeling of these parameters can be done, specifically by introducing an additional mechanism of energy loss (scalar radiation, which is particularly relevant for regimes with relatively little damping) and a modified momentum parameter which is a function of velocity (in analogy to what was previously done for cosmic strings). We finally show that this extended model, appropriately calibrated, provides an accurate fit to our simulations.

description: The activity of the Quadrantids in January during several years (2008, 2010, 2011 and 2012) has been investigated in the framework of the SPanish Meteor Network (SPMN). For this purpose, an array of high-sensitivity CCD video devices and CCD all-sky cameras have been used to obtain multi-station observations of these meteors. These allowed us to obtain precise radiant and orbital information about this meteoroid stream. This paper presents a large set of orbital data (namely, 85 orbits) of Quadrantid meteoroids. Most meteors produced by these particles were recorded during the activity peak of this shower. Besides, we discuss four Quadrantid emission spectra. The tensile strength of Quadrantid meteoroids has been also obtained.

An Analysis of Dereveberation Algorithms on Music Signals
Creators: name: Rios-Rubiras, Roger
Publisher: name: Zenodo
Year: 2014

description: The acquisition of a clean audio from distant microphones is often affected by the phenomenon of reverberation. On speech signals, the reverberation affects the intelligibility. Different ways to minimize this effect on speech signals have been studied during recent years because this is important in fields such as Automatic Speech Recognition. In music, the reverberation is an important aspect to take into account considering that it adds a sense of space and therefore, the effect is not negative. However, taking control over the reverberation could be interesting in order to clean the signal or maybe to manipulate it by changing the reverberation. In this study one commercial plug-in, named as NML RevCon, has been studied and evaluated by using a set of instrumental sounds. The algorithm behind the plugin is one of the algorithms with most chance of success to achieve clean audio, and it is based on the multi step linear prediction technique. The database was built from a set of anechoic sounds, convolved with three different impulses responses and de-reverberated with the mentioned plug-in. Having the sounds in these three states was important in order to evaluate, later, the behaviour of the plug-in. Since the plugin has a set of control parameters, the de-reverberated process has been done four times for each sample with different parameter settings. The evaluation has been done by extracting the frequency-weighted segmental signal to noise ratio, from the comparison between the anechoic sample and the de-reverberated sample. The results show that the speech sound achieves better results after the plug-in process than the instrument sounds. Taking into account only the instrument samples, the best results are achieved by the viola sounds. In addition an analysis has been done of how the plugin behaves with different playing techniques. The results show that the sounds with well defined onsets, like pizzicato or staccato, have better results than the sounds like legato or detaché.

description: Für die Bewältigung der globalen Herausforderung durch die Gestaltung einer nachhaltigen Entwicklung braucht es die Kompetenzen einer Bildung für nachhaltige Entwicklung (BNE) als Schlüssel-Skills für alle relevanten Berufsbilder. Dieser Ansatz kommt im UNESCO-Programm „BNE-2030“ zum Ausdruck (National Action Plan On Education For Sustainable Development (NAP) 2017), das den Fahrplan zur Verankerung von BNE im Bildungssektor darstellt. Die Verankerung von BNE in den hochschulrelevanten Rahmendokumenten wird von der Arbeitsgemeinschaft „Nachhaltigkeit an Brandenburger Hochschulen“ unterstützt. Die vorliegende Handreichung zur curricularen Verankerung von Hochschulbildung für nachhaltige Entwicklung (HBNE) ist ein Beitrag zur Capacity Building an den Brandenburger Hochschulen. (Hochschul-)Bildung für nachhaltige Entwicklung wird als Bildungsansatz verstanden. „Bildung für nachhaltigen Entwicklung bereitet Menschen darauf vor, aktiv mit den Problemen umzugehen, die eine nachhaltige Entwicklung unseres Planeten bedrohen, und gemeinsam Lösungen für diese Probleme zu finden. Bildung für nachhaltige Entwicklung (BNE) bedeutet also das empowerment, als Agent*in des Wandels an der Transformation zu sozial gerechteren und ökologisch integren Gesellschaften mitzuwirken.“ (Bellina et al. 2020, S.24). In der Handreichung zur curricularen Verankerung von HBNE werden drei Handlungsbereiche beleuchtet: I. Die Verankerung von Schlüsselkompetenzen für Nachhaltigkeit (Brundiers et al. 2021) in den Studiengängen bzw. in deren Modulbeschreibungen, II. die thematisch-inhaltliche Verankerung von Nachhaltigkeit am Beispiel der Sustainable Development Goals (SDGs) und III. Bildung für nachhaltige Entwicklung didaktisch-methodisch in der Hochschullehre implementieren. Bei der Implementierung dieser drei Elemente wird eine spiral-curriculare Verankerung von HBNE angestrebt, womit ein Studiengang ganzheitlich betrachtet und die Verankerung schrittweise und niveauabhängig vollzogen werden kann. Diese Vorgehensweise ermöglicht verschiedenste Implementierungsmuster und einen kontinuierlichen Kompetenzaufbau im Laufe des Studiums.

Year: 2014

description: This Master’s thesis focuses on the unexplored domain of animal vocalizations. In the present work Lemur (madagascarian mammal) vocalizations are studied and analysed in order to create a system that can process and train datasets and posteriorly synthesize vocalizations. To achieve the goal the technique of Hidden Markov Models based synthesis is used with the HMM-based speech synthesis system (HTS) toolbox, based on the wide known Hidden Markov Model Toolkit (HTK) speech recognition system. In the following pages a system to synthesize lemur vocalizations is presented and its advantages and inconveniences defined.
