Simulation of Rayleigh-Bénard convection using lattice Boltzmann method

Year: 1996
Subjects: subject: Cellular Automata and Lattice Gases (nlin.CG)
subject: FOS: Physical sciences

description: Rayleigh-Bénard convection is numerically simulated in two- and three-dimensions using a recently developed two-component lattice Boltzmann equation (LBE) method. The density field of the second component, which evolves according to the advection-diffusion equation of a passive-scalar, is used to simulate the temperature field. A body force proportional to the temperature is applied, and the system satisfies the Boussinesq equation except for a slight compressibility. A no-slip, isothermal boundary condition is imposed in the vertical direction, and periodic boundary conditions are used in horizontal directions. The critical Rayleigh number for the onset of the Rayleigh-Bénard convection agrees with the theoretical prediction. As the Rayleigh number is increased higher, the steady two-dimensional convection rolls become unstable. The wavy instability and aperiodic motion observed, as well as the Nusselt number as a function of the Rayleigh number, are in good agreement with experimental observations and theoretical predictions. The LBE model is found to be efficient, accurate, and numerically stable for the simulation of fluid flows with heat and mass transfer.

description: In this paper user modeling task is examined by processing a gallery of photos and videos on a mobile device. We propose novel engine for user preference prediction based on scene recognition, object detection and facial analysis. At first, all faces in a gallery are clustered and all private photos and videos with faces from large clusters are processed on the embedded system in offline mode. Other photos may be sent to the remote server to be analyzed by very deep models. The visual features of each photo are obtained from scene recognition and object detection models. These features are aggregated into a single user descriptor in the neural attention block. The proposed pipeline is implemented for the Android mobile platform. Experimental results with a subset of Photo Event Collection, Web Image Dataset for Event Recognition and Amazon Fashion datasets demonstrate the possibility to process images very efficiently without significant accuracy degradation. The source code of Android mobile application is publicly available at https://github.com/HSE-asavchenko/mobile-visual-preferences.

description: We apply a diagrammatic approach to study Higgs boson, a color-neutral heavy particle, production in nucleus-nucleus collisions in the saturation framework without quantum evolution. We assume the strong coupling constant much smaller than one. Due to the heavy mass and colorless nature of Higgs particle, final state interactions are absent in our calculation. In order to treat the two nuclei dynamically symmetric, we use the Coulomb gauge which gives the appropriate light cone gauge for each nucleus. To further eliminate initial state interactions we choose specific prescriptions in the light cone propagators. We start the calculation from only two nucleons in each nucleus and then demonstrate how to generalize the calculation to higher orders diagrammatically. We simplify the diagrams by the Slavnov-Taylor-Ward identities. The resulting cross section is factorized into a product of two Weizsäcker-Williams gluon distributions of the two nuclei when the transverse momentum of the produced scalar particle is around the saturation momentum. To our knowledge this is the first process where an exact analytic formula has been formed for a physical process, involving momenta on the order of the saturation momentum, in nucleus-nucleus collisions in the quasi-classical approximation. Since we have performed the calculation in an unconventional gauge choice, we further confirm our results in Feynman gauge where the Weizsäcker-Williams gluon distribution is interpreted as a transverse momentum broadening of a hard gluons traversing a nuclear medium. The transverse momentum factorization manifests itself in light cone gauge but not so clearly in Feynman gauge. In saturation physics there are two different unintegrated gluon distributions usually encountered in the literature: the Weizsäcker-Williams gluon distribution and the dipole gluon distribution. The first gluon distribution is constructed by solving classical Yang-Mills equation of motion in the McLerran-Venugopalan model, while the second gluon distribution is related to the dipole scattering amplitude. So far, the quantum structure of the dipole gluon distribution has not been thoroughly investigated. Applying the same diagrammatic techniques, we carry out a detail study of the quantum structure of the color dipole gluon distribution, and then compare it with that of the Weizsäcker-Williams gluon distribution.

 REMARKS: The lamella characteristica in a male from the Peloponnese, Greece differs in shape from those illustrated in the literature (Simon, 1884, 1929; Helsdingen et al., 1977). A small material of T. herbicola from Tuscany and Corsica has shown that the shape of the lamella characteristica is really somewhat variable, but the main reason of variation for such differences lies in the different angles at which the specimens were illustrated. The shape of the posterior median plate of the epigyne is indeed different in two samples from the same population.
This species is here reported for the first time for the Greek fauna.

description: Astrophysical dust -- any condensed matter ranging from tens of atoms to micron sized grains --  accounts for about one third of the heavy elements produced in stars and disseminated into space.  These tiny pollutants are responsible for producing the mottled appearance in the spray of light we call the "Milky Way."  However these seemingly inert particles play a strong role in the physics of the interstellar medium, aiding star and planet formation, and perhaps helping to guide galaxy evolution.  Most dust grains are transparent to X-ray light, leaving a signature of atomic absorption, but also scattering the light over small angles.  Bright X-ray objects serendipitously situated behind large columns of dust and gas provide a unique opportunity to study the dust along the line of sight.  I focus primarily on X-ray scattering through dust, which produces a diffuse halo image around a central point source.  Such objects have been observed around X-ray bright Galactic binaries and extragalactic objects that happen to shine through the plane of the Milky Way. I use the Chandra X-ray Observatory, a space-based laboratory operated by NASA, which has  imaging resolution ideal for studying X-ray scattering halos.  I examine several bright X-ray objects with dust-free sight lines to test their viability as templates and develop a parametric model for the Chandra HETG point spread function (PSF).

description: We report measurements of parallax and proper motion for five 6.7-GHz methanol maser sources in the outer regions of the Perseus arm as part of the BeSSeL Survey of the Galaxy. By combining our results with previous astrometric results, we determine an average spiral arm pitch angle of $9.2\pm1.5$ deg and an arm width of 0.39 kpc for this spiral arm. For sources in the interior side of the Perseus arm, we find on average a radial inward motion in the Galaxy of $13.3\pm5.4$ km s$^{-1}$ and counter to Galactic rotation of $6.2\pm3.2$ km s$^{-1}$. These characteristics are consistent with models for spiral arm formation that involve gas entering an arm to be shocked and then forming stars. However, similar data for other spiral arms do not show similar characteristics.

It appears also in the concept of purifications of mixed states in quantum physics. Here we determine its scalar curvature and Ricci tensor and prove a lower bound for the curvature on the submanifold of trace one matrices. This bound is achieved for the maximally mixed state, a further hint for the quantum statistical meaning of the scalar curvature.

description: Constructed wetlands have been used to remove iron from coal mine acid mine drainage and have been proposed for removal of other heavy metals and acid. The authors are conducting a constructed wetland experiment to treat AMD seepage at Bell Mine. Feed copper concentration and flow rate can be varied, and effects on the disposition of deposited metals will be measured, statistically evaluated, and related to season and meteorology. Vegetation metal uptake and sulphate reducing bacterial activity in the sediments will be assessed for a four year period. The results should enable the mining industry to better assess the role for constructed and natural wetlands in AMD treatment. Sedge and cat-tail have been transplanted from nearby Newman Lake into test ponds, and baseline evaluation work is in progress. Loading of the ponds with AMD is expected in mid-1991. The paper will present a status report on progress of the experiment at Bell Mine.

It is shown that it is possible to multiply throughout by this momentum operator. Factor ordering differences can result in a viscosity term.

description: In-situ diffuse neutron scattering experiments revealed that when electric current is passed through single crystals of rutile TiO2 under conditions conducive to flash sintering, it induces the formation of parallel planes of oxygen vacancies. Specifically, a current perpendicular to the c-axis generates planes normal to the (132) reciprocal lattice vector, whereas currents aligned with the c-axis form planes normal to the (132) and to the (225) vector. The concentration of defects increases with incresing current. The structural modifications are linked to the appearance of signatures of interacting Ti3+ moments in magnetic susceptibility, signifying a structural collapse around the vacancy planes. Electrical conductivity measurements of the modified material reveal several electronic transitions between semiconducting states (via a metal-like intermediate state) with the smallest gap being 27 meV. Pristine TiO2 can be restored by heating followed by slow cooling in air. Our work suggests a novel paradigm for achieving switching of electrical conductivity related to the flash phenomenon

description: Selecting the best code solution from multiple generated ones is an essential task in code generation, which can be achieved by using some reliable validators (e.g., developer-written test cases) for assistance. Since reliable test cases are not always available and can be expensive to build in practice, researchers propose to automatically generate test cases to assess code solutions. However, when both code solutions and test cases are plausible and not reliable, selecting the best solution becomes challenging. Although some heuristic strategies have been proposed to tackle this problem, they lack a strong theoretical guarantee and it is still an open question whether an optimal selection strategy exists. Our work contributes in two ways. First, we show that within a Bayesian framework, the optimal selection strategy can be defined based on the posterior probability of the observed passing states between solutions and tests. The problem of identifying the best solution is then framed as an integer programming problem. Second, we propose an efficient approach for approximating this optimal (yet uncomputable) strategy, where the approximation error is bounded by the correctness of prior knowledge. We then incorporate effective prior knowledge to tailor code generation tasks. Both theoretical and empirical studies confirm that existing heuristics are limited in selecting the best solutions with plausible test cases. Our proposed approximated optimal strategy B4 significantly surpasses existing heuristics in selecting code solutions generated by large language models (LLMs) with LLM-generated tests, achieving a relative performance improvement by up to 50% over the strongest heuristic and 246% over the random selection in the most challenging scenarios.

description: For any given spacetime the choice of time coordinate is undetermined. A particular choice is the absolute time associated with a preferred vector field. Using the absolute time Hamilton's equations are $- (δH_{c})/(δq)=\dotπ+Θπ, $+ (δH_{c})/(δπ)=\dot{q}$, where $Θ= V^{a}_{.;a}$ is the expansion of the vector field. Thus there is a hitherto unnoticed term in the expansion of the preferred vector field. Hamilton's equations can be used to describe fluid motion. In this case the absolute time is the time associated with the fluid's co-moving vector. As measured by this absolute time the expansion term is present. Similarly in cosmology, each observer has a co-moving vector and Hamilton's equations again have an expansion term. It is necessary to include the expansion term to quantize systems such as the above by the canonical method of replacing Dirac brackets by commutators. Hamilton's equations in this form do not have a corresponding sympletic form. Replacing the expansion by a particle number $N\equiv exp(-\intΘd \ta)$ and introducing the particle numbers conjugate momentum $π^{N}$ the standard sympletic form can be recovered with two extra fields N and $π^N$. Briefly the possibility of a non-standard sympletic form and the further possibility of there being a non-zero Finsler curvature corresponding to this are looked at.

description: A recent experimental study [Pan et al., arXiv: 1902.10262] has shown that fractional quantum Hall effect gaps are essentially consistent with particle-hole symmetry in the lowest Landau level. Motivated by this result, we consider a clean two dimensional electron system (2DES) from the viewpoint of composite fermion mean-field theory. In this short note, we show that while the experiment is manifestly consistent with a Dirac composite fermion theory proposed recently by Son, it can equally well be explained within the framework of non-relativistic composite fermions, first put forward by Halperin, Lee, and Read.

description: A simple model collisionless, dissipative, compressible MHD (Alfvenic) turbulence in a magnetized system is investigated. In contrast to more familiar paradigms of turbulence, dissipation arises from Landau damping, enters via nonlinearity, and is distributed over all scales. The theory predicts that two different regimes or phases of turbulence are possible, depending on the ratio of steepening to damping coefficient (m_1/m_2). For strong damping (|m_1/m_2|<1), a regime of smooth, hydrodynamic turbulence is predicted. For |m_1/m_2|>1, steady state turbulence does not exist in the hydrodynamic limit. Rather, spikey, small scale structure is predicted.

description: In the present work we study acceleration waves in plate-like bodies using the balance laws for the time-dependent von Karman equations presented in [P. A. Djondjorov and V. M. Vassilev, Conservation Laws and Group-Invariant Solutions of the von Karman Equations, Int. J. Nonlinear Mech. 31 (1), pp. 73-87, (1986)]. Two of these balance laws correspond to the time-dependent von Karman equations themselves. They are used to define acceleration waves in thin isotropic elastic plates as discontinuity solutions with finite jumps of second derivatives of the displacement field at a certain curve - the wave front. These two balance laws lead through Hadamard's lemma and Kotchin's theorem to a set of jump conditions on the wave front. Similarly, the other balance laws lead to additional and independent jump conditions on the curve of discontinuity. Several examples are given to illustrate the effect of involving jump conditions of that kind in analysis of acceleration waves in plates. The examples are composed on the basis of three families of group-invariant solutions to the time-dependent von Karman equations. They present three kinds of waveforms pertaining to the class of the so-called relatively undistorded progressive waves. We analyze the propagation of this special kind of acceleration waves into a known state of plate motion.

description: The nature and abundance of sulfur chemistry in protoplanetary disks (PPDs) may impact the sulfur inventory on young planets and therefore their habitability. PPDs also present an interesting test bed for sulfur chemistry models, since each disk present a diverse set of environments. In this context, we present new sulfur molecule observations in PPDs, and new S-disk chemistry models. With ALMA we observed the CS 5-4 rotational transition toward five PPDs (DM Tau, DO Tau, CI Tau, LkCa 15, MWC 480), and the CS 6-5 transition toward three PPDs (LkCa 15, MWC 480 and V4046 Sgr). Across this sample, CS displays a range of radial distributions, from centrally peaked, to gaps and rings. We also present the first detection in PPDs of $^{13}$CS 6-5 (LkCa 15 and MWC 480), C$^{34}$S 6-5 (LkCa 15), and H$_2$CS $8_{17}-7_{16}$, $9_{19}-8_{18}$ and $9_{18}-8_{17}$ (MWC 480) transitions. Using LTE models to constrain column densities and excitation temperatures, we find that either $^{13}$C and $^{34}$S are enhanced in CS, or CS is optically thick despite its relatively low brightness temperature. Additional lines and higher spatial resolution observations are needed to distinguish between these scenarios. Assuming CS is optically thin, CS column density model predictions reproduce the observations within a factor of a few for both MWC 480 and LkCa 15. However, the model underpredicts H$_2$CS by 1-2 orders of magnitude. Finally, comparing the H$_2$CS/CS ratio observed toward the MWC~480 disk and toward different ISM sources, we find the closest match with prestellar cores.

Semiclassical Lp Estimates for Quasimodes on Submanifolds

Subjects: eigenfunction estimate, restriction to submanifold, semiclassical analysis

description: Motivated by the desire to understand classical-quantum correspondences, we study concentration phenomena of approximate eigenfunctions of a semiclassical pseudodifferential operator $P(h)$. Such eigenfunctions appear as steady state solutions of quantum systems. Here we think of $h$ as being a small parameter such that $h^{2}$ is inversely proportional to the energy of such a system. As we understand classical mechanics to be the high energy (or small $h$) limit of quantum mechanics we expect the behaviour of eigenfunctions $u(h)$ for small $h$ to be related to properties of the associated classical system. In particular we study the connection between the classical flow and the quantum concentration properties. ¶ ...

Phase-locked loops--Design and construction

description: Phase locked loops (PLLs) used to generate high precision clocks are integral components in the majority of modern day electronic systems such as Analog-to-Digital Converters (ADC), Digital-to-Analog Converters (DAC), transceivers, processors, etc. The accuracy of this clocks that effects the overall performance of the system is measured in terms of its jitter, phase noise, spurious tones, etc. For example, the jitter in an ADC sampling clock can result in uncertainty of the sampling instant and can result in degradation of the effective number of bits (ENOB) of the ADC, phase noise on the other hand can result in reciprocal mixing in receivers and leakage into adjacent channels in transmitters. Therefore it is very desirable to design PLLs that generate clean clocks with minimal area and power consumption. This thesis discusses two PLL prototypes in 65nm CMOS technology. The first prototype demonstrates a sub-sampling phase detector (SSPD) based feed-forward noise cancellation (FFNC) scheme in a Type-II ring oscillator (RO) PLL. The FFNC technique uses the already available noise information at the SSPD output and cancels it from the PLL output. The proposed FFNC achieves a 1.4x reduction in jitter, 19.5dB power supply induced noise suppression at the PLL output while consuming a small area of 0.022mm2. The second prototype demonstrates a Type-I SSPD based RO PLL. The SSPD sample-and-hold action generates a steady-state voltage to tune the VCO directly. This eliminates the issue of high reference spurs generally associated with a Type-I PLL. Also the Type-I PLL occupies a very low area of 0.008mm2 as it avoids the usage of bulky integrating capacitor generally used in a Type-II PLL. The PLL with 2.4GHz output achieves a phase noise of -122.6dBc/Hz at a 1MHz offset and the power consumption is 6.1mW. It achieves reference spurs of -64.2dBc, RMSjitter of 422fs and FoMjitter of -239.7dB. In addition to the two prototypes, a theoretical discussion on an auxiliary FFNC (AFFNC) cancellation scheme that can work with a generic Type-II RO PLL is also included. The AFFNC technique uses a stand alone SSPD to extract and cancel noise from the VCO output. The SSPD is embedded into an alignment loop for proper noise extraction and cancellation. Along with AFFNC, which uses one reference edge for noise extraction, a Double Sampled AFFNC (DS-AFFNC) which utilizes both the rising and falling edge of the reference for noise extraction is also included. By using both the reference edges, higher cancellation BW is achieved.

description: Graphene, since its first isolation, carries many promises on its superior properties. However, unlike its conventional two-dimensional (2D) counterparts, e.g. Si and GaAs systems, graphene represents the first 2D systems built on an atomically thin structure. With every atoms on the surface, graphene is severely affected by the environment and the measured properties have not reaching its full potential.
      Avoiding all possible external contamination sources is the key to keep graphene intact and to maintain its high quality electronic properties. To achieve this, it requires a revolution in the graphene device structure engineering, because all factors in a conventional process are scattering sources, i.e. substrate, solvent and polymer residues. With our recent two inventions, i.e. the van der Waals transfer method and the metal-graphene edge-contact, we managed to completely separate the layer assembly and metallization processes. Throughout the entire fabrication process, the graphene layer has never seen any external materials other than hexagonal boron nitride, a perfect substrate for graphene. Both optical and electrical characterizations show our device properties reach the theoretical limit, including low-temperature ballistic transport over distances longer than 20 micrometers, mobility larger than 1 million cm²/Vs at carrier density as high as 2 ×10^12 cm^-2, and room-temperature mobility comparable to the theoretical phonon-scattering limit. Moreover, for the first time, we demonstrate the post-fabrication cleaning treatments, annealing, is no longer necessary, which greatly eases integration with various substrate, such as CMOS wafers or flexible polymers, which can be damaged by excessive heating. Therefore the progress made in this work is extremely important in both fundamental physics and applications in high quality graphene electronic devices. Furthermore, our work also provides a new platform for the high quality heterostructures of the 2D material family.

description: In Ad hoc Network of Nanosensors for Wastage detection, clustering assist in nodal communication and in organization of the data fetched by the nanosensors in the network. The attempt of traditional cluster formation techniques degraded the formation of cluster in a precise manner. The data from the nanosensors which act as the nodes of the network have to be distinctively added into the clusters. The dynamic path selection cluster would achieve this distinct addition by dynamically creating a path to the data as an initial process and then redirecting the data to their appropriate cluster based to the readied scheme. The formation of clusters is evaluated on the bases of the time taken in formation of cluster and the relevance in information clustering. In this paper the dynamic path selection clustering algorithm is deployed to the cluster formation in data from sensor set for the detection of wastage from industries. Based on the data accumulated from the nanosensors the assignment of fetched information is clustered appropriately. The analyses of the resultant obtain on evaluation process shows the cluster formation life time and relevancy in cluster formation has been more feasible than that of the existing approaches.
