Abstract:
Schemes for linear advection modelling in multiple dimensions on structured grids use either time-splitting or an unsplit approach for flux computation. In the case of strongly divergent flows, time-splitting introduces anisotropy in the solution whereas, with the unsplit approach, more mass than actually available may be abstracted from the computational cells, leading for instance to oscillations and sometimes instability. A simple correction for the flux, taking into account the divergence of the flow, is proposed to eliminate the problem for the unsplit approach. This correction introduces a limitation on the computational time step. An experiment carried out using a market-available software package shows that the problem above is of practical interest, and that verification procedures of modelling software should take into account simulations under non-uniform flows.

Abstract:
Accurately tracking the moving interface is one of the most critical challenges in numerically modeling grout diffusion in fractures. The traditional Youngs method does not consider fluid transport to the oblique adjacent cell, which leads to repeated calculation and error accumulation. Based on the interface reconstruction technology, this paper introduced the idea of the unsplit algorithm to capture the grout-air interface. The unsplit interface advancement formulas were derived considering the fluid fluxes from the central cell to the oblique adjacent cells in the structured cell system. The numerical method based on the unsplit algorithm was validated by examples of predicting the propagation of expansible grout in a fracture. Results show that the diffusion pattern and grout front position calculated by the proposed method are in better agreement with the analytical solution compared with the traditional split algorithm. The new method can effectively improve the grout-air interface tracking accuracy.

Abstract:
The magnetic ion Gd +3, having L = 0 and J ≠ 0, is unsplit by crystal fields and, unlike the other trivalent L ≠ 0 rare-earth ions (which are crystal-field split), is a pair-breaker in high-temperature superconductors. Consequently two-layer compounds with Gd (i.e., Gd 2-z Ce z CuO 4 and Ba 2 GdRu 1-u Cu u O 6) do not superconduct, but their sister compounds without unsplit and pair-breaking Gd , do superconduct (e.g., Nd 2-z Ce z CuO 4, with crystal-field split Nd , and Sr 2 YRu 1-u Cu u O 6, with L = 0 Y , both superconduct). The superconductivity clearly originates in the oxygen of the SrO or BaO layers, or in interstitial oxygen, not in the CuO 2 planes.

Full text
Abstract:
Ce travail porte sur l’étude d’une méthode d’éléments finis discontinus (ou méthode de type Galerkin Discontinu, DGTD) basée sur l’utilisation d’un maillage hexaédrique régulier, proposée pour la résolution des équations de Maxwell dans le domaine temporel, afin de l’adapter à la caractérisation de structures rayonnantes et de l’associer à des techniques de domaines fictifs. On présente tout d’abord une méthode Galerkin Discontinu s’appuyant sur une formulation centrée pour approcher les flux numériques aux interfaces du maillage et sur un schéma en temps explicite de type saute-mouton. Ainsi le schéma obtenu est non-diffusif, stable, peu dispersif, parfaitement adapté à l’utilisation de maillages localement raffinés de manière non-conforme. La méthode a été dotée de parois absorbantes performantes (modèle Unsplit-PML), permettant de prendre en compte facilement des objets à cheval entre le domaine de calcul et la couche absorbante. Nous avons ensuite utilisé la méthode pour effectuer des calculs d’impédances, de paramètres S et de T. O. S. Sur des structures rayonnantes planaires. La comparaison entre la simulation et la mesure de ces structures montre le bon fonctionnement de la méthode. Nous avons alors couplé une méthode de domaines fictifs avec la méthode DGTD afin de prendre en compte la présence d’objets métalliques à géométries complexes. La méthode des domaines fictifs utilise deux maillages de manière indépendante : un maillage cartésien, pour faire évoluer le champ électromagnétique dans l’espace libre, et un maillage surfacique qui permet de prendre en compte l’objet métallique. La convergence de la méthode (pour la méthode FDTD) est liée à une relation de compatibilité entre le maillage volumique et le maillage surfacique : le plus petit élément du maillage surfacique impose la taille des éléments du maillage volumique. Ainsi, pour des objets présentant de tous petits détails, cette condition n’est assurée que si le maillage volumique est de l’ordre du plus petit élément du maillage surfacique, ce qui peut devenir extrêmement contraignant sans le recours à des techniques de raffinement local, telle que celle rendue possible par la méthode Galerkin Discontinu et utilisée ici
We present in this work a time-domain discontinuous Galerkin finite element method (DGTD) applied and adapted to the time domain numerical characterization of antennas, in association with a fictitious domain approach. Fist, a discontinuous Galerkin method is presented, which is based on centered numerical fluxes and a second order explicit leap-frog time scheme. The scheme obtained is non-diffusive, stable, with low dispersion and perfectly adapted for the use of nonconforming locally refined meshes. To deal efficiently with unbounded problems, we used an unsplitted version of Perfectly Matched layers (UPML). The, we used the DGTD method to calculate impedances, S parameters and VSWR of various planar structures. The comparison between simulation and measurement of theses structures shows the good behaviour of the method. Next, a fictitious domain approach based on the Discontinuous Galerkin timedomain (DGTD) method is developed in order to take into account obstacles with complex geometries. The fictitious domain method uses two independent meshes : a Cartesian grid, for the electromagnetic field propagation, and a surfacic mesh which takes into account the obstacle geometry. In the general case, the convergence of the method is linked to obtaining an uniform inf-sup condition, leading to compatibility condition between the boundary mesh and the volumic mesh, i. E. The volumic space step is linked to the smallest triangle of the srufacic mesh. Thus the constraint can be severe for surfacic meshes with small details, in particular for methods which do not cop easily with locally refined grids (like the FDTD method). A DGTD method is perfectly adapted to the use of local subgridding and allows the control of the volumic meshes dimension

Full text
Abstract:
In this thesis, a new method for the design of unsplit numerical schemes for hyperbolic systems of conservation laws with source terms is developed. Appropriate curves in space-time are introduced, along which the conservation equations decouple to the characteristic equations of the corresponding one-dimensional homogeneous system. The local geometry of these curves depends on the source terms and the spatial derivatives of the solution vector. Numerical integration of the characteristic equations is performed on these curves. In the first chapter, a scalar conservation law with a stiff, nonlinear source term is studied using the proposed unsplit scheme. Various tests are made, and the results are compared with the ones obtained by conventional schemes. The effect of the stiffness of the source term is also examined. In the second chapter, the scheme is extended to the one-dimensional, unsteady Euler equations for compressible, chemically-reacting flows. A numerical study of unstable detonations is performed. Detonations in the regime of low overdrive factors are also studied. The numerical simulations verify that the dynamics of the flow-field exhibit chaotic behavior in this regime. The third chapter deals with the development and implementation of the unsplit scheme, for the two-dimensional, reactive Euler equations. In systems with more than two independent variables there are one-parameter families of curves, forming manifolds in space-time, along which the one-dimensional characteristic equations hold. The local geometry of these manifolds and their position relative to the classical characteristic rays are studied. These manifolds might be space-like or time-like, depending on the local flow gradients and the source terms. In the fourth chapter a numerical study of two-dimensional detonations in performed. These flows are intrinsically unstable and produce very complicated patterns, such as cellular structures and vortex sheets. The proposed scheme appears to be capable of capturing many of the the important details of the flow-fields. Unlike traditional schemes, no explicit artificial-viscosity mechanisms need to be used with the proposed scheme.

Abstract:
abstract: The goal of this paper was to do an analysis of two-dimensional unsplit mass and momentum conserving Finite Volume Methods for Advection for Volume of Fluid Fields with interfaces and validating their rates of convergence. Specifically three unsplit transport methods and one split transport method were amalgamated individually with four Piece-wise Linear Reconstruction Schemes (PLIC) i.e. Unsplit Eulerian Advection (UEA) by Owkes and Desjardins (2014), Unsplit Lagrangian Advection (ULA) by Yang et al. (2010), Split Lagrangian Advection (SLA) by Scardovelli and Zaleski (2003) and Unsplit Averaged Eulerian-Lagrangian Advection (UAELA) with two Finite Difference Methods by Parker and Youngs (1992) and two Error Minimization Methods by Pilliod Jr and Puckett (2004). The observed order of accuracy was first order in all cases except when unsplit methods and error minimization methods were used consecutively in each iteration, which resulted in second-order accuracy on the shape error convergence. The Averaged Unsplit Eulerian-Lagrangian Advection (AUELA) did produce first-order accuracy but that was due to a temporal error in the numerical setup. The main unsplit methods, Unsplit Eulerian Advection (UEA) and Unsplit Lagrangian Advection (ULA), preserve mass and momentum and require geometric clipping to solve two-phase fluid flows. The Unsplit Lagrangian Advection (ULA) can allow for small divergence in the velocity field perhaps saving time on the iterative solver of the variable coefficient Poisson System.

Full text
Abstract:
We discuss a full-waveform based material profile reconstruction in two-dimensional heterogeneous semi-infinite domains. In particular, we try to image the spatial variation of shear moduli/wave velocities, directly in the time-domain, from scant surficial measurements of the domain's response to prescribed dynamic excitation. In addition, in one-dimensional media, we try to image the spatial variability of elastic and attenuation properties simultaneously. To deal with the semi-infinite extent of the physical domains, we introduce truncation boundaries, and adopt perfectly-matched-layers (PMLs) as the boundary wave absorbers. Within this framework we develop a new mixed displacement-stress (or stress memory) finite element formulation based on unsplit-field PMLs for transient scalar wave simulations in heterogeneous semi-infinite domains. We use, as is typically done, complex-coordinate stretching transformations in the frequency-domain, and recover the governing PDEs in the time-domain through the inverse Fourier transform. Upon spatial discretization, the resulting equations lead to a mixed semi-discrete form, where both displacements and stresses (or stress histories/memories) are treated as independent unknowns. We propose approximant pairs, which numerically, are shown to be stable. The resulting mixed finite element scheme is relatively simple and straightforward to implement, when compared against split-field PML techniques. It also bypasses the need for complicated time integration schemes that arise when recent displacement-based formulations are used. We report numerical results for 1D and 2D scalar wave propagation in semi-infinite domains truncated by PMLs. We also conduct parametric studies and report on the effect the various PML parameter choices have on the simulation error. To tackle the inversion, we adopt a PDE-constrained optimization approach, that formally leads to a classic KKT (Karush-Kuhn-Tucker) system comprising an initial-value state, a final-value adjoint, and a time-invariant control problem. We iteratively update the velocity profile by solving the KKT system via a reduced space approach. To narrow the feasibility space and alleviate the inherent solution multiplicity of the inverse problem, Tikhonov and Total Variation (TV) regularization schemes are used, endowed with a regularization factor continuation algorithm. We use a source frequency continuation scheme to make successive iterates remain within the basin of attraction of the global minimum. We also limit the total observation time to optimally account for the domain's heterogeneity during inversion iterations. We report on both one- and two-dimensional examples, including the Marmousi benchmark problem, that lead efficiently to the reconstruction of heterogeneous profiles involving both horizontal and inclined layers, as well as of inclusions within layered systems.

Abstract:
Time splitting is a numerical procedure used in solution of partial differential equations whose solutions allow multiple time scales. Numerical schemes are split for handling the stiffness in equations, i.e. when there are multiple time scales with a few time scales being smaller than the others. When there are such terms with smaller time scales, due to the Courant number restriction, the computational cost becomes high if these terms are treated explicitly. In the present work a nonlinear advective equation is solved numerically using different techniques based on a generalised framework for splitting methods. The nonlinear advective equation was chosen because it has an analytical solution making comparisons with numerical schemes amenable and also because its nonlinearity mimics the equations encountered in atmospheric modelling. Using the nonlinear advective equation as a test bed, an analysis of the splitting methods and their influence on the split solutions has been made. An understanding of influence of splitting schemes requires knowledge of behaviour of unsplit schemes beforehand. Hence a study on unsplit methods has also been made. In the present work, using the nonlinear advective equation, it shown that the three time level schemes have high phase errors and underestimate energy (even though they have a higher order of accuracy in time). It is also found that the leap-frog method, which is used widely in atmospheric modelling, is the worst among examined unsplit methods. The semi implicit method, again a popular splitting method with atmospheric modellers is the worst among examined split methods. Three time-level schemes also need explicit filtering to remove the computational mode. This filtering can have a significant impact on the obtained numerical solutions, and hence three-time level schemes appear to be unattractive in the context of the nonlinear convective equation. Based on this experience, splitting methods for the two-time level schemes is proposed. These schemes realistically capture the phase and energy of the nonlinear advective equation.

Thesis (MPA.) -- University of Limpopo, 2017
In 1994 the South African democratically elected government inherited one of the most inequitable access to basic service between rural and urban communities. Rural people used to live without access to basic services such as water, electricity, roads and sanitation facilities. South African government established the Municipal Infrastructure Investment Framework as the national Strategic Plan to outline the extent of basic infrastructure backlogs and to come up with strategies to improve basic service provision to the poor citizens. The Municipal Infrastructure Grant (MIG) is a municipal infrastructure funding which combines all the existing capital grants for municipal infrastructure into a single consolidated grant. MIG is aimed at assisting the poor to gain access to infrastructure. MIG funding can only be used for infrastructure for basic services. Polokwane local municipality and Blouberg local municipality are the beneficiaries of MIG. The purpose of the study was to investigate the causes of unspent Municipal Infrastructure Grants in Polokwane and Blouberg local municipalities. An extensive literature review has been undertaken to gather information regarding unspent Municipal Infrastructure Grants in the two municipalities in the Capricorn District; Polokwane and Blouberg local municipalities. The study provides an investigation on how Polokwane and Blouberg local municipalities monitor the Municipal Infrastructure funding. The study further investigate the capacity of the municipalities to implement MIG, and whether these municipalities have the capacity to effectively utilise the MIG for efficient and effective service delivery. The researcher utilised a qualitative approach to collect data through interview schedule. A satisfactory response rate of 98% was obtained. The results indicated that Polokwane and Blouberg local municipalities are capacitated to implement and to monitor MIG. However, the municipalities often spend less than the budgeted MIG, as a result progress in the access to basic services is hindered. The failure to adequately spend the MIG by these municipalities is due to the fact that there is poor planning and a lot of political interference in the Supply Chain Management processes. The study recommended that managers should do proper planning beforehand, avoid late appointment of service providers and make references on the service providers they appoint to avoid disputes from members of the community. The study further recommended that Polokwane and Blouberg local municipalities should do proper consultation of the project, budget accordingly, and appoint companies that will produce positive end results with value for money. The study recommended that political office bearers should not interfere in the supply chain management processes.

Abstract:
In course of this paper, the authors have sought to trace the various contours of the manner in which the concept of corporate social responsibility has evolved in India, culminating into its inclusion into the governing legislations for companies. The apparent shift of the CSR regime from being a voluntary one to a mandatory one involving sanctions for non-compliance via the latest legislative amendments has also been commented upon. After having discussed the key legislative provisions that govern CSR spending by companies by India, the paper goes on to highlight some of the legislative amendments relating to CSR and the potential impact thereof, including relaxations provided to start-up companies, the mandatory transfer of unspent CSR funds to escrow funds and eventually to public funds centrally controlled by the government, the additional compliance monitoring authority granted to the government, and the penal provisions for non-compliance. The paper finally refers to the draft Companies (Amendment) Bill, 2020 and its possible effect on the CSR regime in India that is looking more and more like corporate taxation with these new amendments.

In the late eighties, they had observed that with the professionalization of the oil industry in earlier decades the wealth that it generated attained chimerical qualities in Venezuela. Such rapid development that obscured the realities of a largely agrarian nation whose modernization was artificially fed by petrodollars. Here, I borrow from GeorgesBataille’s treatises on ritualistic expenditure and his argument that economic wealth and growth governed the physical force field of all organic phenomena. I propose that by the early sixties Venezuela’s unspent energetic surplus had begun to unleash a destructive process from popular segments of the population that, it may be argued, is climaxing in present-day Chavismo. Bataille’s thinking revealed the paradox of utility, or life “beyond [the realm] of utility” as he described it: its ultimate end could only be uselessness as sovereignty was achieved only by those who consumed but did not labor.

Abstract:
This chapter first outlines the linguistic situation of Italy in the first decades of the nineteenth century. It then investigates the role that schooling had in spreading Italian in the post-unification period, with particular attention given to issues that concerned the female sex, now that state schools catered for young girls as well as boys. Controversies surrounding women's education were as alive as ever in the second half of the nineteenth century, with a decisive role being played by the question of how mothers could effectively and competently contribute to make Italian the language used in the family. If mothers could not instruct their children to use the national language competently — something that was now perceived as a good citizen's duty — female teachers, the ‘maestre’, were called to step in. They were entrusted with the quasi-religious task of spreading education and language to children, irrespective of the hardships and sacrifices that their poorly paid and unjustly undervalued profession imposed upon them. In a difficult linguistic situation, in which access to Italian still had to be gained with effort and study, Tuscan women (even if uneducated) were, contrary to the majority of women across the peninsula, in the privileged position of being considered the repository of an unspoilt form of language which flowed naturally from their lips. Some renowned non-Tuscan men of letters actively sought their help and assistance to give the language of their works that spontaneity they so much aspired to and did not possess.

Abstract:
An alternative discretization and solution procedure for implicitly solving a 3-D microscale heat transport equation during femtosecond laser heating of nanoscale metal films has been developed (Kunadian et al. [1]). The proposed numerical technique directly solves a single partial differential equation, unlike other techniques available in the literature which splits the equation into a system of two equations and then apply discretization. The present paper investigates performance of its split and unsplit methods of solution via numerical experiments using Gauss–Seidel, conjugate gradient, generalized minimal residual and δ-form Douglas–Gunn time-splitting methods to compare the computational cost involved in these methods. The comparison suggests that the unsplit method [1] employing δ-form Douglas–Gunn spatial time-splitting is the most efficient way in terms of CPU time taken to complete the simulation of solving the 3-D time dependent microscale heat transport equation.

Abstract:
Abstract Accurate predictions with quantifiable uncertainties are essential to many practical turbulent flow applications exhibiting extreme geometrical complexity and broad ranges of length and time scales. Under-resolved computer simulations are typically unavoidable in such applications, and implicit large-eddy simulation (ILES) often becomes the effective strategy. We focus on ILES initialized with well-characterized 2563 homogeneous isotropic turbulence datasets generated with direct numerical simulation (DNS). ILES is based on the LANL xRAGE code, and solutions are examined as function of resolution for 643, 1283, 2563, and 5123 grids. The ILES performance of new directionally-unsplit high-order numerical hydrodynamics algorithms in xRAGE is examined. Compared to the initial 2563 DNS, we find longer inertial subranges and higher turbulence Re for directional-split 2563 & 5123 xRAGE — attributed to having linked DNS (Navier-Stokes based) solutions to nominally inviscid (higher Re) Euler based ILES solutions. Alternatively — for fixed resolution, we find that significantly higher simulated turbulence Re can be achieved with unsplit (vs. split) discretizations.
