Is the Dark Halo of the Milky Way Prolate?

description: We introduce the flattening equation, which relates the shape of the dark halo to the angular velocity dispersions and the density of a tracer population of stars. It assumes spherical alignment of the velocity dispersion tensor, as seen in the data on stellar halo stars in the Milky Way. The angular anisotropy and gradients in the angular velocity dispersions drive the solutions towards prolateness, whilst the gradient in the stellar density is a competing effect favouring oblateness. We provide an efficient numerical algorithm to integrate the flattening equation. Using tests on mock data, we show that the there is a strong degeneracy between circular speed and flattening, which can be circumvented with informative priors. Therefore, we advocate the use of the flattening equation to test for oblateness or prolateness, though the precise value of the flattening $q$ can only be measured with the addition of the radial Jeans equation. We apply the flattening equation to a sample extracted from the Sloan Digital Sky Survey of $\sim 15000$ halo stars with full phase space information and errors. We find that between Galactocentric radii of 5 and 10 kpc, the shape of the dark halo is prolate, whilst even mildly oblate models are disfavoured. Strongly oblate models are ruled out. Specifically, for a logarithmic halo model, if the asymptotic circular speed $v_0$ lies between $210$ and 250 kms$^{-1}$, then we find the axis ratio of the equipotentials $q$ satisfies $1.5 \lesssim q \lesssim 2$.

description: We obtain higher dimensional solutions for super compact star for the Buchdahl-Vaidya-Tikekar metric ansatz. In particular, Vaidya and Tikekar characterized the $3$-geometry by a parameter, $K$ which is related to the sign of density gradient. It turns out that the key pressure isotropy equation continues to have the same Gauss form, and hence $4$-dimensional solutions can be taken over to higher dimensions with $K$ satisfying the relation, $K_n = (K_4-n+4)/(n-3)$ where subscript refers to dimension of spacetime. Further $K\geq0$ is required else density would have undesirable feature of increasing with radius, and the equality indicates a constant density star described by the Schwarzschild interior solution. This means for a given $K_4$, maximum dimension could only be $n=K_4+4$, else $K_n$ will turn negative.

description: This paper examines the interaction of an intense fermion field with all of the particle species of an attometer primordial black hole's (PBH)'s high energy Hawking radiation spectrum. By extrapolating to Planck-sized PBH's, it is shown that, although Planck-sized PBH's closely simulate the zero absorption requirement of white holes, the absorption probability is not truly zero, and therefore, thermodynamically, Planck-sized PBH's are not true white holes.

Automatic analysis of time varying metrical structures in music

Subjects: Automatic Rhythm Recognition; Bayesian Inference; Metrical Changes

description: Automatic rhythm analysis is an important area of research in Music Information
 Retrieval (MIR) as it aims to develop algorithmic models to study the phenomenon
 of beat induction, an action intuitive and almost instinctual to human listeners.
 Automatic methods to detect rhythmic as well as musical attributes of a musical
 piece like tempo, beats, meter are studied widely in the literature. In this thesis,
 we explore time varying metrical structures in music from the perspective of
 meter inference and tracking. Time varying metrical structures are a part of various
 music cultures and genres like classical music, African music, progressive rock
 music etc. This thesis aims to infer and track the musical meter of such musical
 pieces by proposing extensions to a data driven Bayesian model which simultaneously
 infers the tempo, beats and downbeats of a musical piece. It is shown here
 that by adapting this method for time varying metrical structures, the model learns
 probabilistic relations for transitions between different rhythm patterns and hence,
 metrical changes can be detected within a musical piece. Audio files (containing percussion
 patterns) and their annotations (containing information about the metrical
 structure) are synthesized to validate the approach. Novel evaluation strategies are
 proposed for this case, as the present evaluation measures do not incorporate the
 metrical inference accuracy for musical pieces with changing metrical structures.

description: We present thermoelectric power and resistivity measurements in the ferromagnet UGe$_2$ as a function of temperature and magnetic field. At low temperature, huge quantum oscillations are observed in the thermoelectric power as a function of the magnetic field applied along the $a$ axis. The frequencies of the extreme orbits are determined and an analysis of the cyclotron masses is performed following different theoretical approaches for quantum oscillations detected in the thermoelectric power. They are compared to those obtained by Shubnikov-de Haas experiments on the same crystal and previous de Haas-van Alphen experiments. The agreement of the different probes confirms thermoelectric power as an excellent probe to extract simultaneously both microscopic and macroscopic information on the Fermi-surface properties. Band-structure calculations of UGe$_2$ in the ferromagnetic state are compared to the experiment.

description: Based on the Kubo formula approach, the spin Hall conductivity (SHC) of a two-dimensional (2D) Rashba s-wave superconductor in the presence of nonmagnetic impurities is calculated. We will show that by increasing the superconducting gap, the SHC decreases monotonically to zero, while by decreasing the concentration of impurities at zero gap, the SHC closes to the clean limit universal value . As a function of the impurity relaxation rate at and (is the spin-orbit coupling in unit of), we will show that in the dirty limit () the SHC vanishes, and by increasing the relaxation time () the SHC depends on the value of superconducting gap (), is changed from zero for full gap to in zero gap. At low temperatures, the SHC goes to zero exponentially and near the critical temperature depending on the concentration of the scattering centers, the SHC will tend to the value of normal state. We will also show that the SHC is independent of spin-orbit coupling () in the clean limit.

Interfaces for Improvising with a Jazz Melody Generation System
Creators: name: Munday, Joe
Publisher: name: Zenodo
Year: 2017

description: Computational models of melody can provide expert knowledge to novices, allowing for access
 to musical creativity without the need for extensive formal training. This thesis attempts to
 demonstrate that melody creation and composition can be computationally modelled, and
 documents the development of an interactive model of jazz melody generation intended to be
 used in a live performance context. By incorporating a melody generation system, developed
 using variable order Markov chains, which takes into account the harmonic context at each
 moment, relevant and stylistically consistent note suggestions are delivered to a user in real time.
 Focussing on jazz melodies specifically, two prospective interfaces were developed that allow a
 performer interact and direct the melody generation in collaboration with the system, allowing for
 live performance. Real world instrument metaphors were eschewed in favour of novel interfaces
 that deal with the affordances of readily available technology, such as touch screen devices. Both
 computational and human evaluation of the melodic output of the system are proposed, along
 with user testing in order to review both the musical and performance aspects of the system.

description: Reaction-diffusion systems with time-delay defined on complex networks have been studied in the framework of the emergence of Turing instabilities. The use of the Lambert W-function allowed us get explicit analytic conditions for the onset of patterns as a function of the main involved parameters, the time-delay, the network topology and the diffusion coefficients. Depending on these parameters, the analysis predicts whether the system will evolve towards a stationary Turing pattern or rather to a wave pattern associated to a Hopf bifurcation. The possible outcomes of the linear analysis overcome the respective limitations of the single-species case with delay, and that of the classical activator-inhibitor variant without delay. Numerical results gained from the Mimura-Murray model support the theoretical approach.

Operator means of probability measures and generalized Karcher equations

Publisher: name: arXiv
Year: 2016
Subjects: subject: Functional Analysis (math.FA)
subject: Operator Algebras (math.OA)
subject: FOS: Mathematics

description: In this article we consider means of positive bounded linear operators on a Hilbert space. We present a complete theory that provides a framework which extends the theory of the Karcher mean, its approximating matrix power means, and a large part of Kubo-Ando theory to arbitrary many variables, in fact, to the case of probability measures with bounded support on the cone of positive definite operators. This framework characterizes each operator mean extrinsically as unique solutions of generalized Karcher equations which are obtained by exchanging the matrix logarithm function in the Karcher equation to arbitrary operator monotone functions over the positive real half-line. If the underlying Hilbert space is finite dimensional, then these generalized Karcher equations are Riemannian gradients of convex combinations of strictly geodesically convex log-determinant divergence functions, hence these new means are the global minimizers of them, in analogue to the case of the Karcher mean as pointed out. Our framework is based on fundamental contraction results with respect to the Thompson metric, which provides us nonlinear contraction semigroups in the cone of positive definite operators that form a decreasing net approximating these operator means in the strong topology from above.

Measuring groove: A Computational Analysis of Timing and Dynamics in Drum Recordings
Creators: name: Troes, Tessy
Publisher: name: Zenodo
Year: 2017
Subjects: Groove; Micro-timing; Dynamics; Music Perception; Drums; Electronic Music Production

description: This thesis presents the implementation of a generative groove system, improving
 on currently available humanisers for electronic music production. This is achieved
 by complementing perceptual observations about rhythm and groove with the computational
 analysis of musical recordings of real-life drummers. First, an extensive
 literature review on rhythm perception, groove and groove generation is carried out
 and a working definition for groove is given. Providing additional downbeat annotations
 for the ENST-Drums dataset, we measure the micro-timing deviations from
 an idealised metrical grid as well as the amplitude fluctuations of three different
 drummers. These results are interpreted through various graphical representations
 and validated by a statistical analysis, making use of various machine learning techniques.
 A better understanding of each drummer’s behaviour on a sixteenth-stepand
 beat-level is gained; furthermore, it is found that the genres of “disco” and “rock”
 can be characterised by their micro-timing deviations. We then design an algorithm
 for the generation of genre-specific micro-timing deviation patterns, which then trigger
 events in a digital drum machine. The resulting loops can be correctly classified,
 thus providing us with a proof of concept that we can better understand the generation
 of drum grooves and build more natural, multi-dimensional computer-based
 systems.

description: We consider a Neumann-Robin spectral problem in a perforated domain $\Omeps$. By homogenization techniques we find the suitable homogenized problem and we discuss the asymptotics of eigenpairs, as the size of the perforation tends to zero. Our results involve an approach based on Višík lemma and the Mosco convergence of eigenspaces. We prove that eigenpairs of our problem converge to eigenpairs of the homogenized problem with rate $\sqrt{\eps}$.

description: HI shells, which may be formed by the activity of young and massive stars, or connected to energy released by interactions of high-velocity clouds with the galactic disk, may be partly responsible both for the destruction of CO clouds and for the creation of others. It is not known which effect prevails. We study the relation between HI shells and CO in the outer parts of the Milky Way, using HI and CO surveys and a catalogue of previously identified HI shells. For each individual location, the distance to the nearest HI shell is calculated and it is specified whether it lies in the interior of an HI shell, in its walls, or outside an HI shell. The method takes into account irregular shapes of HI shells. We find a lack of CO clouds in the interiors of HI shells and their increased occurrence in walls. Properties of clouds differ for different environments: interiors of HI shells, their walls, and unperturbed medium. CO clouds found in the interiors of HI shells are those that survived and were robbed of their more diffuse gas. Walls of HI shells have a high molecular content, indicative of an increased rate of CO formation. Comparing the CO fractions within HI shells and outside in the unperturbed medium, we conclude that HI shells are responsible for approx. 20 % increase in the total amount of CO in the outer Milky Way.

description: One of the most challenging tasks in microarray image analysis is spot segmentation. A solution to this problem is to provide an algorithm than can be used to find any spot within the microarray image. Circular Hough Transformation (CHT) is a powerful feature extraction technique used in image analysis, computer vision, and digital image processing. CHT algorithm is applied on the cDNA microarray images to develop the accuracy and the efficiency of the spots localization, addressing and segmentation process. The purpose of the applied technique is to find imperfect instances of spots within a certain class of circles by applying a voting procedure on the cDNA microarray images for spots localization, addressing and characterizing the pixels of each spot into foreground pixels and background simultaneously. Intensive experiments on the University of North Carolina (UNC) microarray database indicate that the proposed method is superior to the K-means method and the Support vector machine (SVM).

In this model, the incoherent light is approximated by a cosine power-modulated light with modulation parameters depending on the coherent time and the dispersion in fibers. A simple and practical method for spectral broadening predictions is given and demonstrated by both the straightforward NLSE-based numerical modeling and series of experiments including narrowband and broadband incoherent light in passive fibers and fiber amplifiers.

description: Conjoint analysis is concerned with the measurement of psychological judgment, suchas customer preferences. The theoretical development of this analysis in the behavioral scienceand its adoption to marketing is of recent origin. Now, an interesting extension of thismethodology is its application to the design of “optimal” products and product lines. It makes useof Design Of Experiments (DOE) for collection and analysis of product data. In this study,conjoint analysis is used to evaluate and test simultaneously multiple concepts of the rear-viewmirror of an auto-rickshaw. The various attributes, their levels and customer preference of theseattributes were gathered by an extensive interaction with the users (auto drivers). Prototypes werebuilt for different combination of attributes and attribute levels and tested for customersatisfaction. Results were analyzed to determine optimal attribute levels that can give highestcustomer satisfaction. It is demonstrated that conjoint analysis can be effectively used in theevaluation and testing of multiple concepts simultaneously and to determine the optimal values ofdesign attributes, which can give higher customer satisfaction.
Audio Source Separation Using Deep Neural Networks
Creators: name: Chandna, Pritish
Publisher: name: Zenodo
Year: 2016

description: This thesis presents a low latency online source separation algorithm based on convolutional neural networks. Building on ideas from previous research on source separation, we propose an algorithm using a deep neural network with convolutional layers. This type of neural network has resulted in state-of-the-art techniques for several image processing problems. We try to adapt these ideas to the audio domain, focusing on low-latency extraction of 4 tracks (vocals, bass, drums and other instruments) from a single-channel (monaural) musical recording. We try to minimize processing time for the algorithm without compromising on performance through data compression. The Mixing Secrets Dataset 100 (MSD100) and the Demixing Secrets Dataset 100 (DSD100) are used for evaluation of the methodology . The results achieved by the algorithm show a 8.4 dB gain in SDR and a 9 dB gain in SAR for vocals over the state-of-the-art deep learning source separation approach using recurrent neural networks.The system’s performance is comparable with other state-ofthe- art algorithms like non-negative matrix factorization, in terms of separation performance, while improving significantly on processing time. This thesis is a stepping block for further research in this area, particularly for implementation of source separation algorithms for medical purposes like speech enhancement for cochlear implants, a task that requires low-latency.

description: Time-resolved magnetic sensing is of great importance from fundamental studies to applications in physical and biological sciences. Recently the nitrogen-vacancy (NV) defect center in diamond has been developed as a promising sensor of magnetic field under ambient conditions. However the methods to reconstruct time-resolved magnetic field with high sensitivity are not yet fully developed. Here, we propose and demonstrate a novel sensing method based on spin echo, and Haar wavelet transform. Our method is exponentially faster in reconstructing time-resolved magnetic field with comparable sensitivity over existing methods. Further, the wavelet's unique features enable our method to extract information from the whole signal with only part of the measuring sequences. We then explore this feature for a fast detection of simulated nerve impulses. These results will be useful to time-resolved magnetic sensing with quantum probes at nano-scales.

description: If dark matter consists of weakly interacting massive particles (WIMPs), dark matter subhalos in the Milky Way could be detectable as gamma-ray point sources due to WIMP annihilation. In this work, we perform an updated study of the detectability of dark matter subhalos as gamma-ray sources with the Fermi Large Area Telescope (Fermi LAT). We use the results of the Via Lactea II simulation, scaled to the Planck 2015 cosmological parameters, to predict the local dark matter subhalo distribution. Under optimistic assumptions for the WIMP parameters --- a 40 GeV particle annihilating to $b\bar{b}$ with a thermal cross-section, as required to explain the Galactic center GeV excess --- we predict that at most $\sim 10$ subhalos might be present in the third Fermi LAT source catalog (3FGL). This is a smaller number than has been predicted by prior studies, and we discuss the origin of this difference. We also compare our predictions for the detectability of subhalos with the number of subhalo candidate sources in 3FGL, and derive upper limits on the WIMP annihilation cross-section as a function of the particle mass. If a dark matter interpretation could be excluded for all 3FGL sources, our constraints would be competitive with those found by indirect searches using other targets, such as known Milky Way satellite galaxies.

DJ Codo Nudo: a novel method for seamless transition between songs for electronic music
Creators: name: Parera, Jaume
Publisher: name: Zenodo
Year: 2016

description: This thesis presents a novel methodology for selecting, ordering and mixing songs, in an effort to emulate a human DJ. The algorithm presented herewith builds on work done on these individual tasks and combines them. Since the goal of the thesis is to emulate a human performance, a Turing test is used for evaluation, wherein human subjects are asked to distinguish the performance of the algorithm from that of a human being. While the research presented is thorough, it must be understood as a stepping-stone for further work in this area and not the finished product capable of mimicking the art of DJing, which requires years of hard work and dedication to accomplish. The proposed algorithm entered in the The AlgoRythms Turing test proposed by the Neukom Institute for Computational Science, in collaboration with the Digital Music and Sonic Arts programs at Dartmouth University and was awarded joint first place.

description: Experimental observations of high-energy surface melting processes, such as laser welding, have revealed unsteady, often violent, motion of the free surface of the melt pool. Surprisingly, no similar observations have been reported in numerical simulation studies of such flows. Moreover, the published simulation results fail to predict the post-solidification pool shape without adapting non-physical values for input parameters, suggesting the neglect of significant physics in the models employed. The experimentally observed violent flow surface instabilities, scaling analyses for the occurrence of turbulence in Marangoni driven flows, and the fact that in simulations transport coefficients generally have to be increased by an order of magnitude to match experimentally observed pool shapes, suggest the common assumption of laminar flow in the pool may not hold, and that the flow is actually turbulent. Here, we use direct numerical simulations (DNS) to investigate the role of turbulence in laser melting of a steel alloy with surface active elements. Our results reveal the presence of two competing vortices driven by thermocapillary forces towards a local surface tension maximum. The jet away from this location at the free surface, separating the two vortices, is found to be unstable and highly oscillatory, indeed leading to turbulence-like flow in the pool. The resulting additional heat transport, however, is insufficient to account for the observed differences in pool shapes between experiment and simulations.

Universal corner contributions to entanglement negativity

description: It has been realised that corners in entangling surfaces can induce new universal contributions to the entanglement entropy and Rényi entropy. In this paper we study universal corner contributions to entanglement negativity in three- and four-dimensional CFTs using both field theory and holographic techniques. We focus on the quantity $χ$ defined by the ratio of the universal part of the entanglement negativity over that of the entanglement entropy, which may characterise the amount of distillable entanglement. We find that for most of the examples $χ$ takes bigger values for singular entangling regions, which may suggest increase in distillable entanglement. However, there also exist counterexamples where distillable entanglement decreases for singular surfaces. We also explore the behaviour of $χ$ as the coupling varies and observe that for singular entangling surfaces, the amount of distillable entanglement is mostly largest for free theories, while counterexample exists for free Dirac fermion in three dimensions. For holographic CFTs described by higher derivative gravity, $χ$ may increase or decrease, depending on the sign of the relevant parameters. Our results may reveal a more profound connection between geometry and distillable entanglement.

Drums and Bass Interlocking
Creators: name: Calopa, Pere
Publisher: name: Zenodo
Year: 2016

description: This thesis presents the technical and theoretical details of a generative system that considers the stylistic rhythmic interaction (interlocking) between bass and drums in the context of Electronic Dance Music (EDM). The concept of rhythmic interlocking, commonly known as groove, has been vaguely studied and is still an open research field. Before designing the generative system it has been necessary to materialize a rhythmic analysis algorithm that allows to study the rhythmic interlocking between instruments. The proposed rhythmic analysis extends recent work on rhythmic similarity that computes syncopation in a rhythmic pattern based on techniques derived from rhythm perception and cognition literature. The outcome of the analysis makes possible to visualize rhythmic patterns in a low-dimensional space defined by rhythmic features relevant to groove conception (i.e. syncopation and density). In addition, we model both temporal and interlocking context of a given corpus using Markov Chains. Taking advantage of the low-dimensional “cognitive-based” representation of rhythmic patterns, the system is parametrized by global syncopation and density controls for pattern generation. The most relevant contributions of this work are the compilation of literature on the topics of groove and stylistic algorithmic composition, the comparison between different generative approaches, and the software implementation of the proposed methods for analysis, visualization and generation. Results show that our proposals are useful for stylistic modelling and give better comprehension of the problem of rhythmic interlocking. Moreover, the generative system has been implemented and partially evaluated with promising results that encourage further research on the topic.
