description: Approximately half of individuals with traumatic brain injury (TBI) experience changes in their sexual functioning and wellbeing, or sexuality. However, sexuality is rarely discussed, leaving survivors to manage these challenges on their own. In this thesis, the lived experiences of post-TBI sexuality were gathered through interviews with survivors, solutions were co-designed with clinicians at a TBI rehabilitation unit, and the effects and process of implementing these solutions were evaluated. The findings demonstrate that dedicated co-design and implementation efforts can lead to improvements in sexuality support, representing an important step in addressing sexuality as an integral aspect of TBI rehabilitation.
title: Accuray and Advantages of Hybrid Solutions Compared to Direct Noise Calculations for Low-Speed Fan Noise

description: In most industrial applications it is widely accepted that noise is a concern for fan manufacturers due to comfort trends and regulations. However, fan noise prediction is not a headache for engineers anymore thanks to advanced and mature simulation techniques and increasingly available computational resources. Based on their needs, engineers can still choose methods such as: - a direct noise calculation from a compressible CFD solution as a reference solution or hybrid solutions where; - the compressible flow results are coupled with a time domain acoustic propagation technique - the incompressible flow results are coupled with a time domain acoustic propagation technique - the compressible flow results are coupled with a frequency domain acoustic propagation technique - the incompressible flow results are coupled with a frequency domain acoustic propagation technique and other non-listed methods. This presentation focuses on the blade loading noise generated by a virtual low-speed five-blade axial fan which operates under a turbulent jet stream. All five alternative techniques listed above are applied to this fan using commercial finite volume software, which is coupled with a commercial finite element software for the last two bullet points above. It is worth to note that the frequency domain acoustic propagation solution uses a high order finite element model and reconstructs the source terms in frequency domain. First, the competitiveness is challenged in a free-field radiation setup, to demonstrate that all five simulation approaches converge to the same acoustic levels in an anechoic-room like environment. Both tones and broadband responses are cross-validated using a finite-volume solution in one hand, and a finite element model on the other hand. Secondly, the hybrid solution is applied to the free-field solution once more, in order to perform a contribution analysis between two zones representative of the leading-edge and trailing-edge of the blades. The leading-edge zone is found to be dominant in the simulations as expected since the fan operates downstream of a jet. This shows how a hybrid solution complements the workflow and how further acoustic insight can be obtained without rerunning the flow solution. Finally, the acoustic response of an installed fan is computed using the same flow results around the axial fan. The reflection and scattering due to surrounding surfaces are then considered in the finite element acoustic solution. This shows how a frequency domain acoustic solution complements a time domain finite volume flow solution in presence of installation effects.

description: Lithium-salt-based deep eutectic solvents, where the only cation is Li+, are promising candidates as electrolytes in electrochemical energy-storage devices like batteries. We have performed broadband dielectric spectroscopy on three such systems, covering a broad temperature and dynamic range that extends from the low-viscosity liquid around room temperature down to the glassy state approaching the glass-transition temperature. We detect a relaxational process that can be ascribed to dipolar reorientational dynamics and exhibits the clear signatures of glassy freezing. We find that the temperature dependence of the ionic dc conductivity and its room-temperature value also are governed by the glassy dynamics of these systems, depending, e.g., on the glass-transition temperature and fragility. Compared to the previously investigated corresponding systems, containing choline chloride instead of a lithium salt, both the reorientational and ionic dynamics are significantly reduced due to variations of the glass-transition temperature and the higher ionic potential of the lithium ions. These lithium-based deep eutectic solvents partly exhibit significant decoupling of the dipolar reorientational and the ionic translational dynamics and approximately follow a fractional Debye-Stokes-Einstein relation, leading to an enhancement of the dc conductivity, especially at low temperatures. The presented results clearly reveal the importance of decoupling effects and of the typical glass-forming properties of these systems for the technically relevant room-temperature conductivity.

description: The number of people with diabetes is rapidly increasing, yet the burden of complications they experience is not quantified or well described. This thesis aims to fill this research gap. We discovered that heart and blood vessel diseases are the most common complications of diabetes. Additionally, people with diabetes are hospitalised for infections more frequently, have a higher risk of injury, and spend more time in hospital beds than the general population. To tackle these issues, it is essential to enhance diabetes care with better access to heart disease prevention medications, improved vaccination programs, and fall prevention activities.

title: Axial Impeller-only Fans with Optimal Hub-to-tip Ratio and Adapted Blades
Creators: name: Carolus, Thomas
name: Bamberger, Konrad
Publisher: name: UNSPECIFIED
Year: 2022

description: This study targets at determining impeller-only axial fans with optimal hub-to-tip ratio for highest achievable total-to-static efficiency. Differently from other studies, a holistic approach is chosen. Firstly, the complete class of this fans is considered. Secondly, the radial distribution of blade sweep angle, stagger angle, chord length and blade camber are varied to adapt the blades to the complex flow in the hub- and tip region. The tool being used is an optimization scheme with three key components: (i) a database created beforehand by Reynolds-Averaged Navier-Stockes (RANS-) predicted performance characteristics of 14,000 designs, (ii) an artificial neural network as a metamodel for the fan performance as a function of 26 geometrical parameters., (iii) an evolutionary algorithm for optimization, performed with the metamodel. In general, the hub-to-tip ratios for the class of axial impeller-only fans proposed by the optimization scheme are smaller than those obtained applying the classic rules. A second outcome are the shapes of adapted blades which deviate substantially from the classic and even the state-of-the-art "swept-only'' or "swept with dihydral'' design. Chord length, stagger and sweep angle are distributed from hub to tip in a complex manner. The inherent reason is that the scheme tries to minimize not only the dynamic exit loss but also frictional losses due to secondary flows in the hub and tip region which eventually results in the maximum achievable total-to-static efficiency.

description: A 1D Josephson junction loop, doped with a spin-flipper and attached to two thermal reservoirs, operates as a heat engine or a refrigerator, a Joule pump, or even a cold pump. When operating as a quantum heat engine, the efficiency of this device exceeds that of some recent Josephson heat engine proposals. Further, as a quantum refrigerator, the coefficient of performance of this device is much higher than previously proposed Josephson junction-based refrigerators. In addition, this device can be tuned from engine mode to refrigerator mode or any other mode, i.e., Joule pump or cold pump, by either tuning the temperature of reservoirs or via the flux enclosed in the Josephson junction loop. In the presence of spin-flip scattering, we can tune our device from engine mode to other operating modes by only changing the enclosed flux in the Josephson junction loop without changing the temperatures of the reservoirs. This is potentially an advantage with respect to other proposals. This makes the proposed device much more versatile as regards possible applications.

description: The emergence of multidrug-resistant ‘superbugs’, such as Acinetobacter baumannii, has posed a significant global health threat. Polymyxins are our last-line therapeutic options against these multidrug-resistant pathogens. However, resistance to these antibiotics is increasing worldwide. In A. baumannii, resistance to polymyxins is primarily due to modifications to lipid A in the outer membrane. Moreover, A. baumannii can develop polymyxin-dependent resistance due to lipopolysaccharide loss and significant outer membrane remodelling. This thesis aims to provide new mechanistic insights into polymyxin resistance and our findings will contribute to optimising the clinical use of this critical class of last-line antibiotics against multidrug-resistant ‘superbugs’.

description: The average size of connected vertex subsets of a connected graph generalises a much-studied parameter for subtrees of trees. For trees, the possible values of this parameter are critically affected by the presence or absence of vertices of degree 2. We answer two questions of Andrew Vince regarding the effect of degree constraints on general connected graphs. We give a new lower bound, and the first non-trivial upper bound, on the maximum growth rate of the number of connected sets of a cubic graph, and in fact obtain non-trivial upper bounds for any constant bound on the maximum degree. We show that the average connected set density is bounded away from 1 for graphs with no vertex of degree 2, and generalise a classical result of Jamison for trees by showing that in order for the connected set density to approach 1, the proportion of vertices of degree 2 must approach 1. Finally, we show that any sequence of graphs with minimum degree tending to infinity must have connected set density tending to 1/2.

description: The data distribution commonly evolves over time leading to problems such as concept drift that often decrease classifier performance. Current techniques are not adequate for this problem because they either require detailed knowledge of the transformation or are not suited for anticipating unseen domains but can only adapt to domains, where data samples are available. We seek to predict unseen data (and their labels) allowing us to tackle challenges s a non-constant data distribution in a proactive manner rather than detecting and reacting to already existing changes that might already have led to errors. To this end, we learn a domain transformer in an unsupervised manner that allows generating data of unseen domains. Our approach first matches independently learned latent representations of two given domains obtained from an auto-encoder using a Cycle-GAN. In turn, a transformation of the original samples can be learned that can be applied iteratively to extrapolate to unseen domains. Our evaluation of CNNs on image data confirms the usefulness of the approach. It also achieves very good results on the well-known problem of unsupervised domain adaption, where only labels but no samples have to be predicted.

description: The overarching aim of my PhD was to understand the contextual influences that shape how sexualised drug use (SDU) is practiced among men who have sex with men (MSM) in Indonesia to inform the development of SDU harm and risk reduction interventions for MSM. The thesis utilised a mixed-methods approach, with findings presented from three interrelated studies (systematic review and meta-analysis, latent class analysis, and qualitative studies on underlying motivations, and social/structural influences on SDU).The findings described in this thesis indicate an intricate interplay between individual, social, and structural elements influencing SDU practice, and provide strong support for developing tailored harm reduction interventions for MSM who engage in SDU in Indonesia.The complexities surrounding the use of drugs for sexual purposes among MSM in Indonesia, as documented in this thesis, necessitate a tailored and multifaceted harm reduction approach.
title: A Model Fan to Test the Train Piston Effect at Grand Paris Express Metro
Creators: name: Béraud, Elisa

Publisher: name: UNSPECIFIED

description: The "Grand Paris Express" railway network is currently under construction. It has been very quickly predicted that piston effect created by train operated at 110 km/h (68 mph) through a succession of 1,000-2,000 m tunnels and stations with a cadence of 90 seconds in rush hours will differ from the traditional Parisian metropolitan network. The piston effect created in front and behind the train has been estimated to a total pressure variation of +900 Pa / -1400 Pa in a few seconds. The piston effect will be reflected in the stations and in the shafts positioned roughly every 800 m in the tunnels for the intervention of emergency services. These shafts are also used for ventilation, first to control smokes and protect the stations in case of fire in the tunnel, then to ensure air quality in the tunnel when natural ventilation is not sufficient. As a consequence, the equipment in the shafts will face with piston effect and will be subjected to strong variations in pressure. At reduced speed, for comfort use, it is expected the fans will be passed through with a negative airflow and operated in negative pressure. Therefore they will be operated in areas that are not defined by the usual. In order to characterize a "Grand Paris Express" type fan, Eiffage carried out a test bench to test the train piston effect. This test bench is made up of a circuit in which is inserted a Ø1000 mm model fan that has the same aeraulical and mechanical characteristics of the 300 fans that will be installed in the service structures of this new network. The model fan has been first tested in the unexplored area of negative pressure and negative flowrate to define the behavior in the three quadrants of the curve. It is now operated with successive negative and positive forced pressure on hundreds of thousands of cycles to ensure the durability of the equipment on several years of operation.

description: Simultaneous vibration control and energy harvesting of vehicle suspensions have attracted significant research attention over the past decades. However, existing energy harvesting shock absorbers (EHSAs) are mainly designed based on the principle of linear resonance, thereby compromising suspension performance for high-efficiency energy harvesting and being only responsive to narrow bandwidth vibrations. In this paper, we propose a new EHSA design -- inerter pendulum vibration absorber (IPVA) -- that integrates an electromagnetic rotary EHSA with a nonlinear pendulum vibration absorber. We show that this design simultaneously improves ride comfort and energy harvesting efficiency by exploiting the nonlinear effects of pendulum inertia. To further improve the performance, we develop a novel stochastic linearization model predictive control (SL-MPC) approach in which we employ stochastic linearization to approximate the nonlinear dynamics of EHSA that has superior accuracy compared to standard linearization. In particular, we develop a new stochastic linearization method with guaranteed stabilizability, which is a prerequisite for control designs. This leads to an MPC problem that is much more computationally efficient than the nonlinear MPC counterpart with no major performance degradation. Extensive simulations are performed to show the superiority of the proposed new nonlinear EHSA and to demonstrate the efficacy of the proposed SL-MPC.

description: Image reconstruction is an integral part of Magnetic Particle Imaging (MPI). Over the last years, several methods have been proposed for reconstructing MPI images more efficiently and accurately. One major challenge for model-based MPI image reconstruction methods is the realistic modeling of the measurement system; effects like non-linear gradient fields, non-uniform drive fields, space-dependent coil sensitivities, drive frequency filtering and particle relaxation, if not properly accounted for in the model, may yield inaccurate reconstructions. This work addresses these issues by means of an image reconstruction method that accounts for the coil sensitivity, baseline recovery and particle relaxation. We investigate the proposed approach for a 1D MPI setup, and provide an approach for the calculation of the uncertainties of the reconstructed images. Int. J. Mag. Part.

description: The assumption that voters' preferences share some common structure is a standard way to circumvent NP-hardness results in social choice problems. While the Kemeny ranking problem is NP-hard in the general case, it is known to become easy if the preferences are 1-dimensional Euclidean. In this note, we prove that the Kemeny ranking problem remains NP-hard for $k$-dimensional Euclidean preferences with $k\!\ge\!2$ under norms $\ell_1$, $\ell_2$ and $\ell_\infty$, by showing that any weighted tournament (resp. weighted bipartite tournament) with weights of same parity (resp. even weights) is inducible as the weighted majority tournament of a profile of 2-Euclidean preferences under norm $\ell_2$ (resp. $\ell_1,\ell_{\infty}$), computable in polynomial time. More generally, this result regarding weighted tournaments implies, essentially, that hardness results relying on the (weighted) majority tournament that hold in the general case (e.g., NP-hardness of Slater ranking) are still true for 2-dimensional Euclidean preferences.

description: Low speed axial fan used in automotive industry contributes to rising noise pollution levels in the environment that is necessary to mitigate. In this study, we simulated the impact of sweep on noise levels and compared with unswept fan by using Lattice Boltzmann method. Different inlet configurations study showed that in the experiment the strong inflow distortion is present. The quality of an incoming flow field is also responsible for higher broadband levels and tonal noise in absence of a stator in the spectra. The leading edge and trailing edge flow field details agrees very well with experimental recordings. The analysis showed that the swept blades alter the aerodynamic flow field. The backward sweep exhibit reduced blade loading near tip and increased leakage flow. The weak turbulent structures formed due to roll up of leakage flow that interacted with the blade near tip and acts as a major noise source. The standard deviation of pressure contours on blade suggest the potential noise sources. Finally, the noise spectra from simulation is validated with experiment showed a very good agreement.

description: We analyse an extremal question on the degrees of the link graphs of a finite regular graph, that is, the subgraphs induced by non-trivial spheres. We show that if $G$ is $d$-regular and connected but not complete then some link graph of $G$ has minimum degree at most $\lfloor 2d/3\rfloor-1$, and if $G$ is sufficiently large in terms of $d$ then some link graph has minimum degree at most $\lfloor d/2\rfloor-1$; both bounds are best possible. We also give the corresponding best-possible result for the corresponding problem where subgraphs induced by balls, rather than spheres, are considered. We motivate these questions by posing a conjecture concerning expansion of link graphs in large bounded-degree graphs, together with a heuristic justification thereof.

description: Let $K$ be the function field of a curve $C$ over a field $\mathbb{F}$ of either odd or zero characteristic. Following the work by Serre and Mason on $\mathrm{SL}_2$, we study the action of arithmetic subgroups of $\mathrm{SU}(3)$ on its corresponding Bruhat-Tits tree associated to a suitable completion of $K$. More precisely, we prove that the quotient graph "looks like a spider", in the sense that it is the union of a set of cuspidal rays (the "legs"), parametrized by an explicit Picard group, that are attached to a connected graph (the "body"). We use this description in order to describe these arithmetic subgroups as amalgamated products and study their homology. In the case where $\mathbb{F}$ is a finite field, we use a result by Bux, Köhl and Witzel in order to prove that the "body" is a finite graph, which allows us to get even more precise applications.

description: In this work we present a detailed theoretical analysis for the spectral properties of Andreev bound states in the multiterminal Josephson junctions by employing a symmetry-constrained scattering matrix approach. We find that in the synthetic multidimensional space of superconducting phases, crossings of Andreev bands may support non-Abelian SU(2) monopoles with a topological charge characterized by the second class Chern number. We propose that these topological defects can be detected via a nonlinear response measurement of the current autocorrelations. In addition, multiterminal Josephson junction devices can be tested as a hardware platform for realizing holonomic quantum computation.

description: Continuous-variable systems realized in high-coherence microwave cavities are a promising platform for quantum information processing. While strong dynamic nonlinear interactions are desired to implement fast and high-fidelity quantum operations, static cavity nonlinearities typically limit the performance of bosonic quantum error-correcting codes. Here we study theoretical models of nonlinear oscillators describing superconducting quantum circuits with asymmetric Josephson-junctions loops. Treating the nonlinearity as a perturbation, we derive effective Hamiltonians using the Schrieffer-Wolff transformation. We support our analytical results with numerical experiments and show that the effective Kerr-type couplings can be canceled by an interplay of higher-order nonlinearities. This can be better understood in a simplified model supporting only cubic and quartic nonlinearities. Our results show that a cubic interaction allows to increase the effective rates of both linear and nonlinear operations without an increase in the undesired anharmonicity of an oscillator which is crucial for many bosonic encodings.

description: As you go… the roads under your feet, towards the new future (2019–22) was a four-year curatorial research inquiry with partner cells based in Central Asia, China, the Balkans and East Africa that I initially developed in response to the geo-political framework of China’s Belt and Road Initiative (BRI).
This practice-based research teases out threads of interest: tensions between margins and centers, a balance between opacity and visibility, undervalued curatorial and artistic gestures, embracing failure as a learning process, proximity as a condition for knowledge production, and how these knowledges are disseminated locally and globally. These questions emerged as core to the curatorial ethics, responsibilities, and sensibilities engaged in this research.

description: Database systems are becoming increasingly multi-engine. In particular, a main-memory database engine may coexist with a traditional storage-centric engine in a system to support various applications. It is desirable to allow applications to access data in both engines using cross-engine transactions. But existing systems are either only designed for single-engine accesses, or impose many restrictions by limiting cross-engine transactions to certain isolation levels and table operations. The result is inadequate cross-engine support in terms of correctness, performance and programmability. This paper describes Skeena, a holistic approach to cross-engine transactions. We propose a lightweight snapshot tracking structure and an atomic commit protocol to efficiently ensure correctness and support various isolation levels. Evaluation results show that Skeena maintains high performance for single-engine transactions and enables cross-engine transactions which can improve throughput by up to 30x by judiciously placing tables in different engines.

description: Recent results have shown that there is an acceleration in the spread of the size distribution of droplet populations in the region bordering the cloud and undersaturated ambient. We have analyzed the supersaturation balance in this region, which is typically a highly intermittent shearless turbulent mixing layer, under a condition where there is no mean updraft. We have investigated the evolution of the cloud-clear air interface and of the droplets therein via direct numerical simulations. We have compared horizontal averages of the phase relaxation, evaporation, reaction and condensation times within the cloud-clear air interface for the size distributions of the initial monodisperse and polydisperse droplets. For the monodisperse population, a clustering of the values of the reaction, phase and evaporation times, that is around 20-30 seconds, is observed in the central area of the mixing layer, just before the location where the maximum value of the supersaturation turbulent flux occurs. This clustering of values is similar for the polydisperse population but also includes the condensation time. The mismatch between the time derivative of the supersaturation and the condensation term in the interfacial mixing layer is correlated with the planar covariance of the horizontal longitudinal velocity derivatives of the carrier air flow and the supersaturation field, thus suggesting that a quasi-linear relationship may exist between these quantities.

description: The occurrence of quark matter at the center of neutron stars is still in debate. This study defines some semi-empirical parameters that quantify the occurrence and the amount of quark matter at star interiors. These parameters show semi-universal relations across all the EoS. One parameter depends on the shifting of the keplerian mass-radius curve from the static one and shows it is a constant across all EoS. The Z-parameter shows how tidal deformability depends on the quark content of the star and the stiffness of the EoS. The quark content of the star also affects the compactness of the star, and its dependence is almost universal. The empirical parameter gives a bound on the quark content of the star and shows that if the amount of the quark content increases, the stars are likely to collapse into a black hole. It is seen that the change in the mass and radius after PT is linearly proportional to the mass of the parent NS. Given a hadronic EoS, bag constant, and quark coupling constant, one can have a critical mass of the neutron star and the maximum mass of the hybrid star for phase transition without any baryonic mass loss.
