description: We consider local quenches from initial states generated by a single spin-flip in either the true or the false vacuum state of the confining quantum Ising spin chain in the ferromagnetic regime. Contrary to global quenches, where the light-cone behaviour is strongly suppressed, we find a significant light-cone signal propagating with a nonzero velocity besides the expected localised oscillating component. Combining an analytic representation of the initial state with a numerical description of the relevant excitations using the two-fermion approximation, we can construct the spectrum of post-quench excitations and their overlaps with the initial state, identifying the underlying mechanism. For confining quenches built upon the true vacuum, the propagating signal consists of superpositions of left and right-moving mesons escaping confinement. In contrast, for anti-confining quenches built upon the false vacuum it is composed of superpositions of left and right-moving bubbles which escape Wannier-Stark localisation.

description: Large-eddy simulation (LES) is progressively becoming a crucial design tool for the next generation of aeronautical combustion chambers. However, further improvements of the capability of LES is required for predicting pollutant emissions. Indeed, the detailed description of fuel pyrolysis and oxidation requires to take into account hundreds of chemical species involved in the complex non-linear reaction process. The direct integration of such detailed chemistry in LES is not a viable path, because of excessive computational demands and numerical stiffness. Modeling real transportation fuel is further complicated by the fact that kerosenes are complex blends of a large number of hydrocarbon compounds; the exact composition of which is very difficult to determine. In this work, the real-fuel combustion chemistry is described by the Hybrid Chemistry (HyChem) approach; and an LES-compliant Analytically Reduced Chemistry (ARC) is used to allow a direct integration of the fuel chemistry in the LES solver. The ARC mechanism is coupled with the Dynamically Thickened Flame LES model (DTFLES) and a Lagrangian spray description to investigate the turbulent two-phase flow flame of a lean direct injection combustor, fueled with Jet-A. The LES results are compared to experimental data in terms of gas velocity, temperature and major species (CO2 , H2 O, CO, NO) mass fractions. It is found that the proposed methodology accurately predicts both the flow dynamics and pollutant formation, and presents therefore a great potential to study complex flame configurations burning real jet fuels.

description: New technologies and complex systems are being developed in commercial aviation to meet strict requirements regarding fuel consumption, emissions and noise constraints. This motivates the development of multidisciplinary environments to efficiently manage the increasing complexity of the design process. Under the Clean Sky 2 initiative, the ModellIng and Simulation tools for Systems IntegratiON on Aircraft (MISSION) project aims to develop an integrated framework to holistically support the aircraft design, development and validation processes. Within the MISSION framework, this paper proposes a methodology to handle the integration between the aircraft level and the system level in the early phase aircraft design. We demonstrate it for the case of the Landing Gear System in the rejected take-off scenario.
Transient overvoltages and distance protection: problems and solutions
Creators: name: Torelli, Leonardo
Publisher: name: RMIT University
Year: 2024

description: This research investigates the relationship between post fault transient overvoltages and the functionality of the digital distance protection. The study is conducted in a 66kV network with a neutral earth resistor as method to earth the power system.
This paper begins by performing an extensive power system analysis on ground fault transient overvoltages. The study is conducted by using the PSCAD-EMTC software package.

The results of this analysis are discussed to determine the impact of a disturbed voltage signal fed to the distance relay, with particular attention to the polarisation and CVT transient mitigation techniques as implemented by modern relays. This research analyses the characteristics of modern digital distance relays to determine if the transient overvoltages could affect the accuracy and operating time of the protection relay. In addition, this study aims to establish a method to predict the performance of the distance protection relay following a phase to ground fault.

Finally, this thesis provides protection setting advices to support the implementation of modern digital distance protection relays on short lines, lines with ineffective grounding system and weak impedance source.

The results of this study show that fault current limitation and consequent reduction of the thermal stress and aging of the equipment are successfully supported by modern distance relays.

description: Understanding the interface dynamics in non-equilibrium quantum systems remains a challenge. We study the interface dynamics of strongly coupled immiscible binary superfluids by using holographic duality. The full nonlinear evolution of the binary superfluids with a relative velocity shows rich nonlinear patterns toward quantum turbulence, which is reminiscent of the quantum Kelvin-Helmholtz instability. The wave number of the fast growing modes $k_0$ extracted from the interface pattern yields a non-monotonic dependence of the relative velocity, independent of the temperature and interaction. The value of $k_0$ first increases with the velocity difference and then decreases, which stands in sharp contrast to the results of mean-field theory described by the Gross-Pitaevskii equation and is confirmed by using the linear analyses on top of the stationary configuration. We uncover that the critical velocity associated with the maximum correspond to the case when the mean separation of vortices generated by interface instabilities becomes comparable to the vortex size, which could be a universal physical mechanism at strongly interacting superfluids and is directly testable in laboratory experiments.

description: This thesis describes the isolation and structure elucidation of ten novel secondary metabolites from one fungus (Pycnoporus cinnabarinus), four lichens (Chrysothrix xanthina, Candelaria concolor, Ramalina glaucescens and Xanthoria parietina), three algae (Plocamium mertensii, Laurencia filiformis and Laurencia elata), two plants (Haemodorum simplex and Dianella callicarpa) and one sponge (Dactylospongia sp). The structures of these isolated compounds were elucidated by a combination of spectroscopic and chemical methods. This thesis also reports two new crystal structures, the identification of two new methylsilylated derivatives as well as the isolation of thirty seven previously reported compounds in which the complete structural assignment by one and two dimensional nuclear magnetic resonance spectroscopy (NMR) has been carried out on known compounds with incomplete or no N MR spectroscopic data. Furthermore, detailed spectroscopic analyses resulted in the reassignment of 1H and 13C chemical shifts for several previously isolated natural products. The biological screening (antimicrobial, antiviral and antitumor assays) of crude extracts and isolated natural products has also been presented. The application of chemical profiling techniques including GCxGC and high pressure liquid chromatography-nuclear magnetic resonance (HPLC-NMR) were utilised to assist with the natural product dereplication process (chemical profiling), monitor chemical degradations in situ and to identify the presence of new natural products and artefacts. In total, fifteen separate terrestrial and marine organisms were investigated.

description: Determining the evolution of the CNO isotopes in the interstellar medium (ISM) of starburst galaxies can yield important constraints on the ages of superstar clusters (SSCs), or on other aspects and contributing factors of their evolution. Due to the time-dependent nature of the abundances of isotopes within the ISM as they are supplied from processes such as nucleosynthesis or chemical fractionation, this provides the possible opportunity to probe the ability of isotopes ratios to trace the ages of high star forming regions, such as SSCs. The goal of this study is to investigate whether the isotopic variations in SSC regions within NGC253 are correlated with their different ages as derived from stellar population modelling. We have measured abundance ratios of CO, HCN and HCO$^+$ isotopologues in six regions containing SSCs within NGC253 using high spatial resolution (1.6",$\sim 28$pc) data from the ALCHEMI (ALma Comprehensive High-resolution Extragalactic Molecular Inventory) ALMA Large program. We have then analysed these ratios using RADEX radiative transfer modelling, with the parameter space sampled using the nested sampling Monte Carlo algorithm MLFriends. These abundance ratios were then compared to ages predicted in each region via the fitting of observed star formation tracers (such as Br$γ$) to starburst stellar population evolution models. We do not find any significant trend with age for the CO and HCN isotopologue ratios on the timescales for the ages of the SSC* regions observed. The driving factors of these ratios within SSCs could be the Initial Mass Function as well as possibly fractionation effects. To further probe these effects in SSCs over time a larger sample of SSCs must be observed spanning a larger age range.

description: We obtain bounds on dark matter annihilation using 14 years of publicly available Fermi-LAT data from a set of 54 dwarf spheroidal galaxies, using spectral information from 16 energy bins. We perform this analysis using our updated and publicly available code MADHATv2, which can be used to test a variety of models for dark matter particle physics and astrophysics in an accessible manner. In particular, we note that including Carina III in the analysis strengthens constraints on $s$-wave annihilation into two-body Standard Model final states by a factor of $\sim 3$ but broadens the error on the constraint due to the large uncertainty of its $J$-factor. Our findings illustrate the importance of verifying if Carina III is in fact a dwarf spheroidal galaxy and measuring more precisely its $J$-factor. More generally, they highlight the significance of forthcoming discoveries of nearby ultra-faint dwarfs for dark matter indirect detection.

description: The principal possibility of technological implementation of relatively simple and highly productive reformers for natural gas conversion into syngas and hydrogen based on the surface combustion (matrix partial oxidation) of natural gas has been demonstrated. It was shown the possibility to obtain syngas with [H2] up to 54%, [CO] up to 31%, and ratio H2/CO up to 1.7. The specific volume capacity of matrix reformers exceeds that of conventional steam reformers at any rate in 10 times. At that, they allow to convert into syngas without fractionation and deep cleaning hydrocarbon gases of practically any origin and composition.

description: Kunst im öffentlichen Raum steht in engem Zusammenhang mit dem Verlassen der Räume, in denen Kunst üblicherweise stattfindet. Hier bewegt sich Kunst auf die Leute zu. Mit dieser Form des sozialen Zugehens sind neben dem künstlerischen Anspruch auch Probleme verbunden, die der öffentlich Raum mit seinen Menschen mit sich bringt. Zweck und Nutzung des Stadtraums sind klar vorgegeben und seinen Bewohnern bekannt. Wird mit einer Intervention im öffentlichen Raum nun ein „Störfall“ produziert, kann dies die unterschiedlichsten Auswirkungen haben. Im Idealfall wird das Ziel erreicht und eine Wahrnehmungsveränderung oder ein Bedeutungswandel angeregt. In diesem Zusammenhang dürfen die Schriften der Situationistischen Internationale nicht ausgeblendet werden. Eine Umsetzung von Kunst im öffentlichen Raum, wie sie die Situationisten in ihren kunst- und gesellschaftskritischen Theorien beschreiben, kann vermutlich in dieser Form nicht vollkommen im realen Stadtraum umgesetzt werden. Eine radikale Auflösung von privaten und öffentlichen Räumen würde in der Gesellschaft letzlich eine Auflösung von Individualität und Identität jedes Einzelnen bedeuten. Kunst im öffentlichen Raum braucht den Konflikt, die Auseinandersetzung mit vorgefundenen Strukturen um sich in der Stadt entfalten zu können. Dennoch beeinflussen die theoretischen Ansätze der S.I. maßgeblich die Entwicklung späterer Theorien auf dem Gebiet der Stadtforschung. Jeder Einzelne kann, wenn es nach den Situationisten geht, die Stadt als gemeinschaftliches Konstrukt beeinflussen. Die Kunst, die vermeintlich ihre Wirkung auf die Gesellschaft verloren hat und nur noch als Konsumprodukt in einer zur Ware gewordenen Gesellschaft existiert, muss von den falschen Leidenschaften der Menschen losgelöst werden. Durch die bewusste Konstruktion von Situationen soll in einem ersten Schritt die standardisierte Wahrnehmung der Öffentlichkeit gebrochen werden und in einem weiteren Schritt eine neue Urbanität – der Unitäre Urbanismus geschaffen werden. Durch das Aufbrechen der Rolle des passiven Betrachters, die durch die Praktiken des Umherschweifens und der Zweckentfremdung erfolgt, soll der Versuch der Rückeroberung und Wiederbelebung der Stadt für und auch durch die Bewohner erfolgen. So versuchen auch heute künstlerische Stadtprojekte den nicht für die Kunst institutionalisierten Außenraum für sich zu nutzen und die Bevölkerung in den künstlerischen Prozess einzubinden.

description: For small thrust LOX/methane rocket engine, new cryogenic propellant valves which are actuated by an electric motor were developed. The valves have the functions not only for the shut-off valves, but also the control of the propellant flow rate. Since the valves are actuated by the electric motor, the engine system does not need any pneumatic system for them, which mean the engine system can become much simplified. This paper describes the development and test of the prototype cryogenic propellant valves which are actuated by the electric motor for both controlling the propellant mass flow and functioning open and close.

description: Electrical actuators are progressively replacing historical pneumatic systems to control rocket engine valves. This technology not only supresses helium consumption and reduces costs but also greatly facilitates in-flight rocket engine regulation and throttling. Regulation  throttling algorithms can strongly depend on the application, from simple regulation to improve launcher performance, to deep throttling for landing, or soft start-up and shut-down for reusable engines. The range of actuator technologies and power levels is also wide. Testing a newly developed controller directly on an engine fire test can be risky, especially for new engines. Moreover the capability to test the embedded hardware in a wide range of demanding conditions will probably be limited because of costs associated to those tests. Thus, a flexible real-time test bench that can be adapted to a wide variety of applications can really secure the development and testing of new control chains. During the past years, CNES and Airbus Safran Launchers have developed and built a platform that can host real actuators and controller hardware, along with real-time models of launcher stage and engine, coupled with a newly designed tool simulating the resisting torque on the actuator. A first demonstration of a complete hardware-in-the-loop simulation has been achieved in December 2015, validating the capability of the platform to pave the way for Ariane 6 or next generation engines.

Changing drivers, shifting trends: a decade of equity research in Australian vocational education and training (VET) 1996-2006
Creators: name: Volkoff, Veronica
Publisher: name: RMIT University
Year: 2024

description: This integrating essay presents and discusses the findings of the research studies that Veronica Volkoff completed within the context of the shifts in the Australian vocational education and training landscape and resultant trends in vocational education and training policy, in particular equity policy, during the period of researching and writing the nominated works, 1995 to 2004.

The research included analysis of vocational education and training in relation to: equity policy; provider inclusiveness strategies; and access, participation, completion and outcomes in relation to learners, in particular members of designated and emerging equity target groups. A range of methodologies was implemented in these studies, usually utilising a mix of both quantitative and qualitative methods.

The first study, the Longitudinal study of student experiences in vocational education and training, explored the experiences of access, participation and outcomes of students in vocational education and training from a range of equity target groups. It was undertaken in six Australian locations across three states and territories. It revealed that intentions, experiences and outcomes varied across students and equity target groups and that membership of multiple equity target groups compounded disadvantage and had an adverse effect upon outcomes.

The second study, a Review of equity literature, was commissioned to inform national policy and broad strategy development and analysed the situation for five designated equity target groups in vocational education and training, nationally. Two other studies focussed on Vocational education and training for people from non-English speaking backgrounds, undertaken five years apart, reviewed the literature and analysed participation and outcomes for people from non-English speaking backgrounds. A further study analysed the Delivery of vocational education and training programs by adult and community education providers, particularly its provision for people belonging to disadvantaged groups.
Crystallisation spectrometer

description: An improved crystallisation spectrometer has been designed, built and tested. It is to be used by others to gain new knowledge about the solidification of matter by study of the crystallisation of hard sphere colloid samples that are an established model for the behaviour of some aspects of atoms. In this crystallisation spectrometer, expanded and collimated green laser light is Bragg scattered from the colloidal crystals as they form, and the diffracted light is focused by a liquid filled hollow glass hemispherical lens onto low cost CCD array detectors that are rotated about the optical axis to average the intensities around the whole Debye-Scherrer cone of scattered light. The temperature of the sample is controlled to +/-0.1„a, and because of the ability to change the refractive index of the sample particles with temperature, this is utilised to control the amount of scattering from the sample Also, this spectrometer uniquely exploits the refractive index match of the colloidal particles, the solvent, the bath liquid, and the glass used for both the sample bottle and the hollow glass hemisphere. A unique facility has been incorporated to permit tumbling of the sample prior to the measurement commencing to shear-melt any pre-existing crystals. This ensures that the sample is completely fluid and is at the correct temperature at the start of the measurement. The instrument is assembled on an optical table and is computer controlled. Results presented show that this new spectrometer with its use of the whole Debye-Scherrer cone of Bragg scattered light and other enhancements gives insight into the crystallisation process more than one order of magnitude of time earlier than previous light scattering experiments, providing new knowledge about the crystallisation process.

description: We explore the critical properties of a topological transition in a two-dimensional, amorphous lattice with randomly distributed points. The model intrinsically breaks the time-reversal symmetry without an external magnetic field, akin to a Chern insulator. Here, the topological transition is induced by varying the density of lattice points or adjusting the mass parameter. Using the two-terminal conductance and multifractality of the wavefunction, we found that the topological transition belongs to the same universality class as the integer quantum Hall transition. Regardless of the approach to the critical point across the phase boundary, the localization length exponent remains within $ν\approx 2.55 - 2.61$. The irrelevant scaling exponent for both the observables is $y \approx 0.3(1)$, comparable to the values obtained using transfer matrix analysis in the Chalker-Coddigton network. Additionally, the investigation of the entire distribution function of the inverse participation ratio at the critical point shows possible deviations from the parabolic multifractal spectrum at the anomalous quantum Hall transition.

A comprehensive framework with design principles for supporting interaction in fully online courses
Creators: name: Nandi, Dip
Publisher: name: RMIT University
Year: 2024

description: Advances in computer-mediated communication technologies have sparked and continue to facilitate the proliferation of online courses and degree programs in educational institutions. Fully online courses are becoming progressively more popular because of their “anytime anywhere” learning flexibility. These fully online courses are conducted via Internet-based learning environments and there are no face-to-face classes. One important aspect of any online learning environment is interaction. Different types of interactive activities assist students to share and gain knowledge from each other. However, quality interaction in fully online courses does not always take place and there is a lack of clarity about the appropriate role of the instructors in them.

This thesis examines different types of interaction in fully online computing courses and develops frameworks with design principles for supporting quality interaction. By investigating different types of interaction and how quality interaction can be defined, we identify the best practices for fully online course management and provide significant guidelines for improvement of teaching and learning in fully online computing courses.

In the first stage of the research, we investigate the course management factors that impact student participation and achievement in fully online computing courses. We identify several factors that affect student participation and grades. These results provide valuable information about expected student behaviour in fully online computing courses and hence support and add additional knowledge to prior research regarding interaction, undertaken in on-campus and blended learning environments.

In the second stage, we identify two sets of criteria and two frameworks for effective interaction between students and instructors. These frameworks provide guidelines on how quality interaction can be designed and assessed. In the third stage, we evaluate the two frameworks developed in the previous stage.

In the fourth stage of the research, we investigate student – content interaction and identify several factors that impact interaction between students and content. Identification of these factors provides guidelines in setting up and managing effective interaction between students and content.

description: This paper describes work carried out within the Buterfli project to look at the control of transition causing \"target\" stationary cross flow vortices, by the use of distributed plasma actuation to generate sub-dominant \"killer\" modes. The objective is to use the \"killer\" modes to control the \"target\" modes through a non-linear stabilising mechanism. The numerical modelling and results are compared to experimental studies performed at the TsAGI T124 tunnel for a swept plate subject to a favourable pressure gradient flow. A mathematical model for the actuator developed at TsAGI was implemented in a linearised Navier Stokes (LNS) solver and used to model and hence predict \"killer\" mode amplitudes at a measurement plane in the experiment. The LNS analysis shows good agreement with experiment, and the results are used as input for non-linear PSE analysis to predict the effect of these modes on crossflow transition. Whilst the numerical model indicates a delay in transition, experimental results indicated an advance rather than delay in transition; this was determined to be due to actuator induced unsteadiness arising in the experiment, resulting in the generation of travelling crossflow disturbances which tended to obscure and thus dominate the plasma stabilised stationary disturbances.

However, while contemporary sculptural practice explores current ideas of materiality incorporating both sentient and non-sentient agency, by contrast, blacksmithing has struggled to keep up with contemporary thought. From the early 20th century, the social demand for objects made by blacksmiths fell dramatically and its creative techniques stagnated with the demise of its craft-based skills. At the same time, sculptors who used blacksmithing processes did so largely in response to traditional cultural expectations.

This research project explored the historical and material agencies of both blacksmithing and sculpture, including the agencies of material processes acknowledged in Actor-Network Theory. The combination of these methods led to an understanding of sculptural practice with a less formal and more material process. The creative outcomes of this research include a substantial body of work culminating in Fountain: Dance of the water droplet [fig. 2], an artwork focusing on the multiple formative agencies of blacksmithing.

The findings of this research demonstrate the benefits of transposing a highly personal studio practice into an historical revaluation of its innate connections with blacksmithing. This study not only adds to the discourse of artistic materiality, it also aims to establish the traditional craft of blacksmithing as one relevant to contemporary discourse.

description: Three main approaches to the geometrical evolution of ice accretion are presented to discuss the impact of ice mass conservation in ice accretion simulations. An algebraic method, a grid generation method and a level-set method are covered. Each of these methods is developed in two versions, one which is stated as conservative and the other not conservative. First, the iterative version of the algebraic method is conservative. Second, the smoothed grid generation method is globally and locally conservative. Third, the level-set method using the velocity field based on a conserved volume displacement is approaching mass conservation. A verification and a validation of the methods are performed as to compare their behaviour and the effect of ice mass conservation. Verification is performed on a cylinder and a manufactured airfoil with constant ice thickness for each case, showing how some methods handle better than others concave regions and ice thickness strong discontinuities. Validation is done in single- and multi-layer simulations on a glaze ice case and a rime ice case. As expected, conservative methods in multi-layer simulations accord better with the experimental data. In fact, conservative methods allow to reduce the global ice mass error significantly, while local conservation criterion has an effect on the shape of the ice accretion.

description: Complex field imaging, which captures both the amplitude and phase information of input optical fields or objects, can offer rich structural insights into samples, such as their absorption and refractive index distributions. However, conventional image sensors are intensity-based and inherently lack the capability to directly measure the phase distribution of a field. This limitation can be overcome using interferometric or holographic methods, often supplemented by iterative phase retrieval algorithms, leading to a considerable increase in hardware complexity and computational demand. Here, we present a complex field imager design that enables snapshot imaging of both the amplitude and quantitative phase information of input fields using an intensity-based sensor array without any digital processing. Our design utilizes successive deep learning-optimized diffractive surfaces that are structured to collectively modulate the input complex field, forming two independent imaging channels that perform amplitude-to-amplitude and phase-to-intensity transformations between the input and output planes within a compact optical design, axially spanning ~100 wavelengths. The intensity distributions of the output fields at these two channels on the sensor plane directly correspond to the amplitude and quantitative phase profiles of the input complex field, eliminating the need for any digital image reconstruction algorithms. We experimentally validated the efficacy of our complex field diffractive imager designs through 3D-printed prototypes operating at the terahertz spectrum, with the output amplitude and phase channel images closely aligning with our numerical simulations. We envision that this complex field imager will have various applications in security, biomedical imaging, sensing and material science, among others.

WIND TUNNEL

description: In the present manuscript a biconic re-entry model was investigated in a blow down wind tunnel at Mach 1.5, 2, 3, and 4. The main focus was on studying the longitudinal stability and aerodynamic efficiency in this flying regime. In particular, the influence of wings near the rear part of the model, their wing dihedral, and of additional body flaps was investigated. While the purely biconic configuration was unstable, it could be stabilized with wings at a 20 deg downward pitch and with the additional body flaps. In general a larger dihedral angle improved static longitudinal stability.

description: In Österreich ist die Vertretung der Musikermedizin spärlich vorhanden. In Wien an der Universität für Musik und darstellenden Kunst gibt es ein Lehrangebot im 3. Semester, wo eine musikermedizinische Beratung mit praktischen Übungen angeboten wird. Am Mozarteum in Salzburg werden Vorlesungen über Bewegungsphysiologie und Musikermedizin sowie Anatomie, Physiologie und Körperschulung angeboten. Deutschland übernimmt unter anderem eine Vorreiterrolle im Bereich der sogenannten Musikermedizin, welche bereits eine etablierte Position besitzt. Mittlerweile leiden zwei Drittel der Berufsmusiker in Deutschland unter musikerspezifischen Beschwerden. Neben der Behandlung der Erkrankungen, werden Präventionsprogramme für Studierende angeboten, um diese im Bereich der Gesundheit für ihren zukünftigen Beruf vorzubereiten. Immer mehr rückt der Mittelpunkt auf die Gesundheitsförderung in dieser Berufsgruppe. Dabei finden nicht nur professionelle MusikerInnen ihre Beachtung, sondern auch die Laienmusiker. (vlg. Spahn, 2006) Das Projekt Musik & Muskeln - "Locker sein macht stark" wird für Lehrende und Studentierende der Universität für Musik und darstellenden Kunst in Wien angeboten, um ihnen Methoden zu vermitteln, ihren Körper vor berufsbedingten Beschwerden und Krankheiten zu schützen. Dieses Gesundheitsförderungsprojekt startete im Sommersemester 2008 und endet im Wintersemester 2010. Dabei wurde ein prozessorientierte Evaluation durchgeführt. In jedem Projektsemester wurden die Projektteilnehmer per Online-Fragebögen über ihren Gesundheitszustand und allgemeinen Wohlbefinden, unter anderem mit standardisierten, musikerspezifischen Fragebögen, befragt. Diese Befragung wiederholte sich am Ende des Semesters mit einem zusätzlichen Feedback-Fragebogen, in diesem konnten die TeilnehmerInnen die Interventionsmethoden bewerten. Diese Arbeit bearbeitete die Daten der Online-Fragebögen von Sommersemester 2008 bis Sommersemester 2009. Es wurden die vor allem die musikerspezifischen Beschwerden und körperliche Bewegungsaspekte in den Blickpunkt genommen. Mittels deskriptivstatistischer Auswertungen sollte ein Trend für bewegungspezifischer Interventionen für MusikerInnen in Aussicht gestellt werden.

description: Deep generative models complement Markov-chain-Monte-Carlo methods for efficiently sampling from high-dimensional distributions. Among these methods, explicit generators, such as Normalising Flows (NFs), in combination with the Metropolis Hastings algorithm have been extensively applied to get unbiased samples from target distributions. We systematically study central problems in conditional NFs, such as high variance, mode collapse and data efficiency. We propose adversarial training for NFs to ameliorate these problems. Experiments are conducted with low-dimensional synthetic datasets and XY spin models in two spatial dimensions.
