The baroclinic instability in the context of layered accretion. Self-sustained vortices and their magnetic stability in local compressible unstratified models of protoplanetary disks

description: Turbulence and angular momentum transport in accretion disks remains a topic of debate. With the realization that dead zones are robust features of protoplanetary disks, the search for hydrodynamical sources of turbulence continues. A possible source is the baroclinic instability (BI), which has been shown to exist in unmagnetized non-barotropic disks. We present shearing box simulations of baroclinicly unstable, magnetized, 3D disks, in order to assess the interplay between the BI and other instabilities, namely the magneto-rotational instability (MRI) and the magneto-elliptical instability. We find that the vortices generated and sustained by the baroclinic instability in the purely hydrodynamical regime do not survive when magnetic fields are included. The MRI by far supersedes the BI in growth rate and strength at saturation. The resulting turbulence is virtually identical to an MRI-only scenario. We measured the intrinsic vorticity profile of the vortex, finding little radial variation in the vortex core. Nevertheless, the core is disrupted by an MHD instability, which we identify with the magneto-elliptic instability. This instability has nearly the same range of unstable wavelengths as the MRI, but has higher growth rates. In fact, we identify the MRI as a limiting case of the magneto-elliptic instability, when the vortex aspect ratio tends to infinity (pure shear flow). We conclude that vortex excitation and self-sustenance by the baroclinic instability in protoplanetary disks is viable only in low ionization, i.e., the dead zone. Our results are thus in accordance with the layered accretion paradigm. A baroclinicly unstable dead zone should be characterized by the presence of large-scale vortices whose cores are elliptically unstable, yet sustained by the baroclinic feedback. As magnetic fields destroy the vortices and the MRI outweighs the BI, the active layers are unmodified.

description: The need for online 3D interactive experiences was evidenced during the COVID-19 lockdowns, as audiences across the world have been unable to visit museums, physically interact with their collections on site or digitally interact with technologies and digital media situated within such settings. As a response, this research addresses gaps identified in a review of the digital offerings from UK and US museums during the 2020 lockdowns, highlighting the limited number and nature of 3D interactive offerings provided, despite the wide efforts on 3D digitisation over the last decade. Thus, the research investigates the development and testing of an online 3D interactive activity, resembling a physical activity situated in the archaeological gallery of Brighton Museum and Art Gallery (UK). Through a pilot user survey, the research aims to understand what is the impact of such online offerings to better contextualise heritage collections; enhance cultural heritage learning and appreciation; and complement physical activities of similar nature. The analysis of audiences’' opinions about these interactions can be of great importance, as such activities have the power to enable active access to cultural heritage resources regardless of the physical location of users and transform heritage experiences in the long term. Our research indicates that, while the physical experience might offer advantages as far as it concerns the familiarity with the tactile nature of interaction, the digital counterpart has potential to allow for the experience of assembling the puzzle to achieve a wider reach.

description: We study a Hamiltonian system describing a three-spin-1/2 cluster-like interaction competing with an Ising-like anti-ferromagnetic interaction. We compute free energy, spin correlation functions and entanglement both in the ground and in thermal states. The model undergoes a quantum phase transition between an Ising phase with a nonvanishing magnetization and a cluster phase characterized by a string order. Any two-spin entanglement is found to vanish in both quantum phases because of a nontrivial correlation pattern. Neverthless, the residual multipartite entanglement is maximal in the cluster phase and dependent on the magnetization in the Ising phase. We study the block entropy at the critical point and calculate the central charge of the system, showing that the criticality of the system is beyond the Ising universality class.

Lower semicontinuity for integral functionals in the space of functions of bounded deformation via rigidity and Young measures

description: We establish a general weak* lower semicontinuity result in the space $\BD(Ω)$ of functions of bounded deformation for functionals of the form $$\Fcal(u) := \int_Ωf \bigl(x, \Ecal u \bigr) \dd x + \int_Ωf^\infty \Bigl(x, \frac{\di E^s u}{\di \abs{E^s u}} \Bigr) \dd \abs{E^s u} + \int_{\partial Ω} f^\infty \bigl(x, u|_{\partial Ω} \odot n_Ω\bigr) \dd \Hcal^{d-1}$$, $u \in \BD(Ω)$. The main novelty is that we allow for non-vanishing Cantor-parts in the symmetrized derivative $Eu$. The proof is accomplished via Jensen-type inequalities for generalized Young measures and a construction of good blow-ups, which is based on local rigidity arguments for some differential inclusions involving symmetrized gradients. This strategy allows us to establish the lower semicontinuity result without an Alberti-type theorem in $\BD(Ω)$, which is not available at present. We also include existence and relaxation results for variational problems in $\BD(Ω)$, as well as a complete discussion of some differential inclusions for the symmetrized gradient in two dimensions.

description: It is argued that the Heisenberg picture of standard quantum mechanics does not save Einstein locality as claimed in Deutsch and Hayden (2000). In particular, the EPR-type correlations that DH obtain by comparing two qubits in a local manner are shown to exist before that comparison. In view of this result, the local comparison argument would appear to ineffective in supporting their locality claim.

description: A kinetic model of gravimagnetic shock waves (GMSW) in a locally anisotropic plasma is investigated. The equations of a drift approximation are written, and the moments of the distribution function are calculated. Solutions of the drift equations for a highly anisotropic ultrarelativistic plasma are found. It is shown that in this case the GMSW essentially affect the angular characteristics and the intensity of the magneto - bremsstrahlung of the magnetoactive plasma.

Efficient modelling of special purpose multi-phase electrical machines for transient simulation programs
Creators: name: Amiri, Navid
Publisher: name: University of British Columbia
Year: 2019

description: Design and analysis of power systems has always been reliant on mathematical models of power system components and their implementation in sophisticated electromagnetic transient (EMT) simulation programs. Electric machines are the dominantly used components in models of power grids, and in most simulation programs rotating machines are represented using lumped-parameter models based on magnetically-coupled phase windings. Advancements in semi-conductor devices have allowed conventional three-phase machines as well as multi-phase machines (with more than three electrical phases) to be used with power electronic interfaces in wide range of electromechanical energy conversion applications, including advanced motor drive systems as well as integration of renewable energy. The multi-phase machines, at the expense of their increased complexity, may also provide additional advantages over the conventional three-phase machines, e.g. reduced power per phase, reduced semi-conductor current/voltage rating per phase, increased reliability, fault tolerant operation, etc. However, such multi-phase machines have unique electromagnetic characteristics and complex mathematical models which also become additional challenge in terms of both implementation and numerical performance in simulation programs. The main goal of this dissertation is to propose accurate and numerically efficient models of multi-phase machines which also consider key characteristics such as magnetic saturation and flux harmonics. In this dissertation, the voltage-behind-reactance (VBR) methodology has been used to derive new models for wound-rotor six-phase synchronous machines (including leakage flux cross-coupling and magnetic saturation), five-phase machines (including flux harmonics and inter-harmonic couplings) and also three-phase saturable induction machines considering flux harmonic distortions. The new models possess the advantage of constant-parameter interfacing circuits when implemented in state-variable-based (SVB) simulation programs, which has not been possible prior to this work. Numerous case studies demonstrate the advantageous numerical accuracy and efficiency of the proposed models, and their beneficial impact on simulation performance compared to the alternative existing state-of-the-art machine models of the same class. It is envisioned that due to their numerous advantages the new models will become included in many commonly-used commercial EMT programs, and will benefit thousands of researchers and engineers worldwide.

description: We calculate solar models including dark matter (DM) weakly-interacting massive particles (WIMPs) of mass 5-50 GeV and test these models against helioseismic constraints on sound speed, convection zone depth, convection zone helium abundance, and small separations of low-degree p-modes. Our main conclusion is that both direct detection experiments and particle accelerators may be complemented by using the Sun as a probe for WIMP DM particles in the 5-50 GeV mass range. The DM most sensitive to this probe has suppressed annihilations and a large spin-dependent elastic scattering cross section. For the WIMP cross-section parameters explored here, the lightest WIMP masses <10 GeV are ruled out by constraints on core sound speed and low-degree frequency spacings. For WIMP masses 30-50 GeV, the changes to the solar structure are confined to the inner 4% of the solar radius and so do not significantly affect the solar p-modes. Future helioseismology observations, most notably involving g-modes, and future solar neutrino experiments may be able to constrain the allowable DM parameter space in a mass range that is of current interest for direct detection.

description: We consider a particle system of the squared Bessel processes with index $ν> -1$ conditioned never to collide with each other, in which if $-1 < ν< 0$ the origin is assumed to be reflecting. When the number of particles is finite, we prove for any fixed initial configuration that this noncolliding diffusion process is determinantal in the sense that any multitime correlation function is given by a determinant with a continuous kernel called the correlation kernel. When the number of particles is infinite, we give sufficient conditions for initial configurations so that the system is well defined. There the process with an infinite number of particles is determinantal and the correlation kernel is expressed using an entire function represented by the Weierstrass canonical product, whose zeros on the positive part of the real axis are given by the particle-positions in the initial configuration. From the class of infinite-particle initial configurations satisfying our conditions, we report one example in detail, which is a fixed configuration such that every point of the square of positive zero of the Bessel function $J_ν$ is occupied by one particle. The process starting from this initial configuration shows a relaxation phenomenon converging to the stationary process, which is determinantal with the extended Bessel kernel, in the long-term limit.

description: The plasmonic response of nanoparticles is exploited in many subfields of science and engineering to enhance optical signals associated with probes of nanoscale and subnanoscale entities. We develop a numerical algorithm based on previous theoretical work that addresses the influence of a substrate on the plasmonic response of collections of nanoparticles of spherical shape. Our method is a real space approach within the quasi-static limit that can be applied to a wide range of structures. We illustrate the role of the substrate through numerical calculations that explore single nanospheres and nanosphere dimers fabricated from either a Drude model metal or from silver on dielectric substrates, and from dielectric spheres on silver substrates.

description: The theme of the final qualifying work: Â«Two shaft dual-circuit turbojet engine with a thrust of 107,8 kNÂ». The aim of the work is to develop a turbojet dualâcircuit engine with a thrust of 107,8 kN based on a prototype - the aviation turbojet engine D-30KU. The main part of the work is devoted to the calculation of the engine working process parameters manually, as well as on the basis of a computer program and the subsequent selection of rational parameters used to calculate the axial compressor, combustion chamber, engine turbine and its strength characteristics. Also included in the work is a special part describing the methodology for calculating the aerodynamic characteristics of the last stage of the engine turbine. As a result of the calculations, an engine with a given thrust value was designed based on the selected prototype.

description: The recently discovered exoplanet Gl581d is extremely close to the outer edge of its system's habitable zone, which has led to much speculation on its possible climate. We have performed a range of simulations to assess whether, given simple combinations of chemically stable greenhouse gases, the planet could sustain liquid water on its surface. For best estimates of the surface gravity, surface albedo and cloud coverage, we find that less than 10 bars of CO2 is sufficient to maintain a global mean temperature above the melting point of water. Furthermore, even with the most conservative choices of these parameters, we calculate temperatures above the water melting point for CO2 partial pressures greater than about 40 bar. However, we note that as Gl581d is probably in a tidally resonant orbit, further simulations in 3D are required to test whether such atmospheric conditions are stable against the collapse of CO2 on the surface.

description: We propose a scheme of optical pumping by which a system of atoms coupled to harmonic oscillators is driven to an entangled steady state through the atomic spontaneous emission. It is shown that the optical pumping can be tailored so that the many-body atomic state asymptotically reaches an arbitrary stabilizer state regardless of the initial state. The proposed scheme can be suited to various physical systems. In particular, the ion-trap realization is well within current technology.

Collapse of differentially rotating neutron stars and cosmic censorship

description: We present new results on the dynamics and gravitational-wave emission from the collapse of differentially rotating neutron stars. We have considered a number of polytropic stellar models having different values of the dimensionless angular momentum J/M^2, where J and M are the asymptotic angular momentum and mass of the star, respectively. For neutron stars with J/M^2<1, i.e., "sub-Kerr" models, we were able to find models that are dynamically unstable and that collapse promptly to a rotating black hole. Both the dynamics of the collapse and the consequent emission of gravitational waves resemble the one seen for uniformly rotating stars, although with an overall decrease in the efficiency of gravitational-wave emission. For stellar models with J/M^2>1, i.e., "supra-Kerr" models, on the other hand, we were not able to find models that are dynamically unstable and all of the computed supra-Kerr models were found to be far from the stability threshold. For these models a gravitational collapse is possible only after a very severe and artificial reduction of the pressure, which then leads to a torus developing nonaxisymmetric instabilities and eventually contracting to a stable axisymmetric stellar configuration. While this does not exclude the possibility that a naked singularity can be produced by the collapse of a differentially rotating star, it also suggests that cosmic censorship is not violated and that generic conditions for a supra-Kerr progenitor do not lead to a naked singularity.

description: Determination of palladium at trace levels in environmental samples is essential due to its harmful properties and threats to living organisms. Hence, a simple but efficient liquid-phase microextraction method is reported by sieve conducted two syringes pressurized liquid phase microextraction (SCTS-PLPME) and slotted quartz tube flame atomic absorption spectrometry (SQT-FAAS). The originality of this system is based on the elimination of disperser solvents that are used to increase the surface area of extractant. The high pressure created by the movement of syringe plungers results in efficient dispersion of the extractants in the sample solution. Parameters that affect the overall efficiency of the extraction method were carefully optimized. The limit of detection (LOD) and quantification (LOQ) under the optimum conditions were 6.0 and 20.0 μg L−1, respectively. The developed method showed good linearity between 20 and 1000 μg L−1, and provided a 25-fold enhancement in detection power compared to conventional FAAS. The optimized method was successfully used to determine the analyte in precious metal waste samples.

description: Magnetic phase diagram of a spatially anisotropic, frustrated spin-1/2 Heisenberg antiferromagnet on a stacked square lattice is investigated using second-order spin-wave expansion. The effects of interlayer coupling and the spatial anisotropy on the magnetic ordering of two ordered ground states are explicitly studied. It is shown that with increase in next nearest neighbor frustration the second-order corrections play a significant role in stabilizing the magnetization. We obtain two ordered magnetic phases (Neel and stripe) separated by a paramagnetic disordered phase. Within second-order spin-wave expansion we find that the width of the disordered phase diminishes with increase in the interlayer coupling or with decrease in spatial anisotropy but it does not disappear. Our obtained phase diagram differs significantly from the phase diagram obtained using linear spin-wave theory.

description: Olive oil mills and enterprises demand fast and low-cost detection of adulteration from vegetable and seed oils, such as hazelnut, sunflower, soybean, cannabis, corn and almond oil, according to their food fraud mitigation plans. This study describes a method for the detection of adulteration using the k232 and k268 (specific extinctions at wavelengths 232 nm and 268 nm, respectively), and the Δk (the variation of the absolute value of the extinction) values as independent variables in chemometric approaches. Different percentages of seed oils were added to the extra virgin olive oil and the results showed that vegetable and seed oil adulteration above 7.5% (w/w) was easily detected. The developed methodology is low cost, rapid, and simple for adoption by olive oil enterprises in comparison to other techniques. This is the first time that such an easy method may be applied for the olive mills for the protection of consumers using a well-organized food fraud mitigation plan.

description: In this paper, we study a two-dimensional model for the growth of molecular clusters in superfluid helium at low temperature. In the model, particles of diameter a follow random ballistic moves of length δ= a-256a. Upon attachment on the cluster surface, particles allow one-step relaxation to the nearest twofold coordinated site. Average coordination numbers of particles show that in the presence of relaxation the screening for incoming particles modifies the microscopic structure of the cluster. These results are in qualitative agreement with experimental aggregation of methane in He droplets, in which large abundance of fully coordinated sites is observed. The average coordination number increases with δ, showing that screening is relevant when relaxation is present. As the cluster size increases, the corresponding structure clusters changes from a compact to a fractal, typical of ballistic and diffusion limited models, respectively. A scaling ansatz describing the crossover between the two regimes is proposed.

Interplay between spin density wave and $π$ phase shifted superconductivity in the Fe pnictide superconductors

description: We explore if the phase separation or coexistence of the spin density wave (SDW) and superconductivity (SC) states has any relation to the incommensurability of the SDW in the Fe pnictide superconductors. A systematic method of determining the phase separation or coexistence was employed by computing the anisotropy coefficient $β$ from the the 4th order terms of the Ginzburg--Landau (GL) expansion of the free energy close to the tricritical/tetracritical point. It was complemented by the self-consistent numerical iterations of the gap equations to map out the boundaries between the phase separation and coexistence of the SDW and SC phases, and between commensurate (C) and incommensurate (IC) SDW in the temperature--doping plane. Our principal results for the sign reversed $s$-wave pairing SC, in terms of the multicritical temperature, $T_c$, the phase separation/coexistence boundary between the SDW and SC, $T^*$, and the boundary between C/IC SDW, $T_M^*$, are: (a) IC-SDW and SC coexist for $T_c < T^*$ and phase separate otherwise, (b) SDW takes the C form for $T_c>T_M^*$ and IC form for $T_c
