IEEE floating-point arithmetic standards 754 and 854 reflect the present state of the art in designing and implementing floating-point arithmetic units. A formalism applied to a standard non-trapping mode floating-point system shows incorrectness of some numeric and non-numeric results. A software emulation of decimal floating-point computer arithmetic supporting an enhanced set of exception symbols is reported. Some implementation details, discussion of some open questions about utility and consistency of the implemented arithmetic with the IEEE Standards are provided. The potential benefit for computations with infinite symbolic elements is outlined.

Abstract:
Numeric regional models are necessary to reconstruct the nature and conditions of formation of i geological structures, to obtain ideas about the evolution of different zones of the crust and upper mantle, the evolution of fold and fault dislocations and predicting expression of manifestation of deep structures on earth’s surface. Numeric reconstructions are based on computational dynamics methods, in which rock is represented as highly viscous liquid. «Markers-in-cell» method is one of the implementations of that approach. We propose to accelerate model ported into Python, as compared to Matlab, without rejecting sequential enumeration of markers. It is shown that the solutions can be either code vectorization (refactoring with binary indices instead of enumeration loops and numpy functions) or acceleration of loops by their pre-compilation or parallel computations. The results obtained can be used in the implementation of numeric geological modeling in Python.

Abstract:
This paper deals with an implementation method of component-based Petri nets system based on a graphical programming language (LabVIEW). LabVIEW is not only a graphical programming language, but also a virtual instrument platform which is widely used in virtual measurement and control system. The Places (token number) of Petri nets are represented by Numeric Controls of LabVIEW. The Transitions of Petri nets are represented by subVIs of LabVIEW. Transition subVI will change the tokens of Places by the Numeric Controls' Reference when it is fired. This method will make it ease to implement a Petri net by simply combining Place and Transition components (subVI). The example implementing a special Petri net shows that the Front Panel of the controller reflects the system operating state directly; the Block Diagram is similar to the topology of original Petri net. The combination of two graphic languages makes the modeling, analysis and formal verification of measurement and control system based on Petri nets easier.

Abstract:
Purpose: The article presents both numeric implementation in Japan and the Arabic gematrical calculation (hisababajadun) in Indonesia. It is common for the people in Japan and Indonesia to believe in the power of numerals and to assume whether or not certain digits induce bad luck.
 Methodology: The research applies a qualitative descriptive method through a contrastive approach.
 Main Findings: Data analysis is based on both Koizumi's approach (1995) to the meaning of numbers in the Japanese language and Al Bani's view on hisababajadun. Our study shows that the numeric calculation in Japan uses luckiness as its ground while the hisababajadun builds its mechanism on birth date calculation according to Quranic Neuro-Hypnosis.
 Implications/ Applications: The research may enrich existing theoretical references on the belief toward numbers in both Japan and Indonesia. While in practice, it may as well be a reference for the application of numeric calculation methods in both cultures.
 Novelty/Originality of this study: This study is unique and novel as it enhances the understanding of the importance of numerals in two distinct cultures i.e., Japan and Indonesia. Moreover, this study sheds light on some crucial aspects of numeral calculation including how these numerals are used, what beliefs are attached to them and how and where these numerals are used for solving life problems.

Abstract:
In the process of learning a song work, constraints often occur in students' limited memory. The song material given at the first meeting will be forgotten when reviewed at the second meeting, to overcome this we try to apply number notation as a way for students to recall the tone of the song that has been given. The purpose of this study was to determine the efficiency and response of the application of number notation to song learning in junior high school. This study uses a qualitative descriptive method, the data collection technique used in this study is to provide a pre-test and post-test which contains 10 questions regarding numerical notation. The findings of this study gave a positive response to the students, in the initial pre-test found results that were not good because many of the students did not understand numeric notation at all, but after that they were shown a video of reading material notation of numbers and then a post-test was carried out, the results were good. The students made progress after seeing the video. The conclusion of this study is to implement numeric notation in the song learning process, making it easier for students to memorize the material and making it easier for teachers in the process of conveying it, thus it is hoped that it can be a solution to the problems previously mentioned.

Abstract:
<p>We propose a hardware implementation on a field-programmable gate array (FPGA) of the cerebellar model articulation controller (CMAC) with an integer numeric system. Existing hardware implementations of floating-point processes on FPGAs have utilized the IEEE 754 standard, which introduces complex operations leading to long processing times. For the most complex part of the CMAC, that is, the exponential operator, traditional look-up table methods carry high memory costs. We, therefore, use a Taylor series to realize the exponential operator. Finally, we connect all the modules into the CMAC.</p> <p> </p>

Abstract:
In this thesis, a digitalization method with nite word-length (resolu- tion N ) of a given stable analog controller guaranteeing the minimum dierence in terms of frequency responses is treated. The challenge has consisted in nding a relevant frequency responses mismatch met- ric and in relating it to the word niteness issue. The analog con- troller is represented in modal state-space form and digitalized with a stability-maintaining approximation (ramp invariance) for dierent sampling periods. It results in digital controllers with block diago- nal transition matrices whose coecients (poles) are inside the unit circle. The format is chosen to match the poles dynamical range. The matrix is then coded and the mismatch measure allows for the selection of the "best" poles coded controllers. The remaining ma- trices are then scaled and coded for these selected controllers. The measure is computed for each of them. The procedure nally gives the "optimal" coded controller. This algorithm is shown to perform well and better that a simple rounding after the analog controller discretization phase. iii

Abstract:
COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR<br>CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO<br>A relação entre os processos hidrológicos de escoamento superficial e subterrâneo apresenta uma grande variabilidade espacial e temporal. Podendo ser representado de forma qualitativa como parte sequêncial do ciclo hidrológico, estes processos, demostram sua grande dependência e importância nos estudos de balanços hídricos. Visando uma representação quantitativa, este trabalho faz o acoplamento, entre os modelos numéricos de escoamento superficial e de fluxo em meios porosos. Para o meio poroso adotou-se o modelo numérico SWMS_3D (Simunek et al, 1995), o qual resolve a equação de Richards, para fluxo em meios porosos saturados e não saturados nas três dimensões. Na simulação da dinâmica superficial, foram desenvolvidos dois modelos derivados das equações de Saint- Venant: o modelo da Onda Cinemática e o modelo de Difusão. Para a solução numérica foi empregado o método dos elementos finitos através da formulaçao de Galerkin, adotando uma malha tridimensional de elementos tetraédricos, formando uma sub-malha de elementos triangulares na superfície. O modelo de escoamento superficial emprega a malha triangular e interage com o programa SWMS_3D modificado (que utiliza a malha de tetraédros) através das imposições das condições de contorno transientes. Este, responderá com uma parcela de fluxo correspondente à recarga ou descarga no contorno a cada passo de tempo. Com isso, o modelo gerado é capaz de quantificar espacialmente e temporalmente as cargas de pressão em todos os pontos do domínio de estudo.<br>While analyzing the interaction between the hydrological processes of surface and groundwater flow, it is seen that there is a big difference in its interaction in the space and time. These processes can be represented in a qualitative form as part of the hydrological cycle, demonstrating its dependences and importance in the hydrological balance. This work does the numerical coupling of the surface and groundwater flow. This work adopted the SWMS_3D numerical model (Simunek et. al., 1995), which resolves the Richards equation for saturated and non saturated porous media flow in 3D. In order to simulate the superficial dynamic flow, two models from Saint-Vennat equation were developed, these models are: the cinematic wave model and the diffusion model. These two models consider the average outflow in sections in a 2D scenario. For the numerical solution the finite element method was adopted through the Galerkin formulation. Adopting a 3D domain mesh of tetrahedral elements, seen from above, in 2D, we can see a triangular element mesh. The superficial flow model uses the triangular mesh and iterates with the SWMS_3D modified software, which uses the tetrahedral elements mesh. This was done by changes in the boundary conditions to the models. The SWMS_3D will answer with a flow portion corresponding to a sink or source action in the surface, in each time step. Finally the generated model is able to quantify in space and in time the pressure head in the study domain.

Abstract:
Efficient, robust simulation of groundwater flow in the unsaturated zone remains computationally expensive, especially for problems characterized by sharp fronts in both space and time. Standard approaches that employ uniform spatial and temporal discretizations for the numerical solution of these problems lead to inefficient and expensive simulations. Accurate solution of the pressure-head form of Richards' equation is very difficult using standard time integration methods, because the mass balance errors grow unless very small time steps are used in the time integration process. Richards' equation may be solved for many problems more economically and robustly with variable time step size instead of constant time step size. But variable step-size methods applied to date have relied upon empirical approaches to control step size which do not explicitly control truncation error of the solution. In the first part of this thesis, we solve Richards' equation using the method of lines with a finite difference approach. We show how a differential algebraic equation implementation of the method of lines can give solutions to Richards' equation that are accurate, have good mass balance properties, and are more economical for a wide range of solution accuracy. We have implemented the method of lines using the higher order time integration ode solver ode15s to (i) assure robustness for difficult nonlinear problems and computational efficiency; (ii) develop high order adaptive methods for the time discretization taking into account the different time scales that may appear in the process; (iii) investigate the advantage of using higher-order methods in time. The numerical results demonstrate that the proposed method provides a robust and efficientalternative to standard approaches for simulating variably saturated flow in one spatial dimension. In the 2nd part of the thesis, we to investigate the convergence and mass balance behavior in Richards' equation-based solvers. As hydrological models become increasingly sophisticated (e.g., coupling with various meteorological, ecological, or biogeochemical components) and are applied in ever more computationally demanding contexts (e.g., the many realizations that are typically generated in parameter estimation, uncertainty analysis, data assimilation, or scenario studies), the need for robust, accurate, and efficient codes is greater than ever. The Richards equation for subsurface flow is highly nonlinear and requires iterative schemes for its solution. These schemes have been the subject of much research over the past two decades, but an effective all-purpose algorithm has thus far proven elusive. Ideally, rapid (quadratic as opposed to linear) and global (insensitive to initial guess) convergence is sought, in addition to applicability over a range of conditions (dry soils, storm-interstorm simulations, geological heterogeneity, 3D domains with complex boundary conditions, etc). Richards’ equation can be mathematically formulated and numerically discretized in a variety of manners, and the specific form and scheme chosen will affect the mass balance behavior of the model. We implement and test a promising nested Newton-type algorithm for solving Richards' equation. In the current state of the art, the Picard iteration method is widely used for solving the nonlinear equation governing flow in variably saturated porous media because this method is simple to code and computationally cheap. But the convergence is slow and sometimes fails. On the other hand, the Newton method is more complex and expensive than Picard. As a result the Picard method is more attractive than Newton. However, especially for strongly nonlinear flow problems, the robustness and higher rate of convergence makes Newton an attractive alternative in some cases. In this work the Picard and Newton schemes are compared with results of a nested Newton-type algorithm. Three test cases are presented and each problem is solved over a wide range of vertical discretization. The results highlight the different aspects of the performance of the iterative methods and the different factors that can affect their convergence and efficiency, including problem size, spatial and temporal discretization, convergence error norm, mass lumping, time weighting, conductivity, moisture content characteristics, and boundary conditions. It is suggested that nested Newton-type methods can be effectively implemented and used alongside Picard and Newton and numerical models of Richards' equation. In the final part of the thesis, we studied the performance of a lookup table option, as an alternative to analytical calculation, for evaluating the nonlinear soil characteristics needed in the Picard and Newton schemes. This assessment is conducted for the CATHY (CATchment Hydrology) 3D Richards-based subsurface flow solver. The lookup table method can be a cost-effective alternative to analytical evaluation in the case of heterogeneous soils, but it has not been examined in detail in the hydrological modeling literature. Two layered soil test problems are considered, and the robustness and accuracy of the lookup table method are assessed for uniform and nonuniform distributions of lookup points in the soil retention curves<br>Simulazioni robuste ed efficienti del flusso dell’acqua in suolo insaturo è ancora un problema computazionale di difficile soluzione, in particolare nei casi di infiltrazione in suolo relativamente secco per la presenza di grandi gradienti nella soluzione approssimata che esaltano le nonlinearità e rendono difficile la trattazione numerica. Gli approcci tradizionali che impiegano discretizzazioni spaziali e temporali uniformi sono inefficienti e computazionalmente assai costosi, oltre che essere spesso affetti da grandi errori nella conservazione discrete della massa. Algoritmi temporalmente adattativi sono stati proposti ma sono ancora computazionalmente inefficienti in particolare in presenza di forzanti esterne ad alta variabilità, quali quelle causate dai flussi di precipitazione. Nella prima parte di questa tesi viene sperimentato l’approccio risolutivo che impiega tali algoritmi tramite il metodo delle linee (MOL) utilizzando solutori di tipo DAE (DifferentialAlgebraic Equation). Si verifica sperimentalmente che questo modo di procedure può essere preferibile a tecniche a passo fisso per alcuni casi test. Tale approccio, basato su solutori temporali di alto grado di accuratezza, quando applicabile, si dimostra efficiente e competitivo rispetto a metodi più tradizionali, mantenendo buone proprietà di robustezza e conservazione della massa, quando si utilizzino approcci mono-dimensionali. Nella seconda parte della tesi ci si focalizza più direttamente nelle proprietà di convergenza e conservazione della massa di metodi recentemente proposti in letteratura applicati a problemi eterogenei e multidimensionali. La moderna applicazione di modelli idrologici vede un arricchirsi dei processi considerati accoppiando l’equazione di Richards a modelli diversi derivanti da applicazioni metereologiche, ecologiche e bio-geo-chimiche, con la conseguente richiesta di metodi numerici più efficienti e robusti. Idealmente, si richiede a questi schemi una convergenza rapida, possibilmente quadratica, e globale in tutte le circostanze (e.g., suoli aridi, simulazioni “storm-interstorm”, grandi eterogeneità, condizioni al contorno nonlineari, eccetera). Anche il tipo di formulazione matematica dell’equazione di Richards nel continuo (ad esempio in forma completamente conservativa oppure semi-conservativa) determina diverse efficienze dei diversi metodi in funzione delle condizioni forzanti. Per questi motivi, viene implementato e testato in condizioni “estreme” un algoritmo basato sull’applicazione annidata del metodo di Newton e proposto recentemente nella letteratura. La verifica viene fatta per confronto con metodi di Newton e Newton-Picard più tradizionali su tre test sintetici ma realistici e probanti. Per ciascun test si verifica la robustezza dei diversi schemi a variazioni di griglia sia temporale che spaziale, e si confrontano i risultati in termini di velocità di convergenza, e quindi efficienza numerica. I risultati suggeriscono che il nuovo metodo “nested-Newton” risulta assai competitivo dimostrando ottime proprietà di convergenza anche nei test più difficili. Infine, l’ultima parte della tesi è volta a verificare l’efficienza computazionale nell’uso negli schemi di Picard e Newton di tecniche di “look-up” che discretizzano le curve caratteristiche delle relazioni pressione-saturazione (responsabili della nonlinearità nell’equazione di Richards) utilizzando il solutore CATHY (CATchmentHYdrology). I risultati mostrano che l’uso di tabelle di “look-up” migliora l’efficienza computazionale dei metodi alla Newton tradizionali in casi test omogenei e eterogenei rispetto ai metodi analitici qualora le curve caratteristiche possano essere accuratamente descritte da un numero di punti limitato

2008-2009<br>Functional equations provide the best and most natural way to describe evolution in time and space, also in presence of memory. In fact, the spread of diseases, the growth of biological populations, the brain dynamics, elasticity and plasticity, heat conduction, fluid dynamics, scattering theory, seismology, biomechanics, game theory, control, queuing theory, design of electronic filters and many other problems from physics, chemistry, pharmacology, medicine, economics can be modelled through systems of functional equations, such as Ordinary Differential Equations (ODEs) and Volterra Integral Equations (VIEs). For instance, ODEs based models can be found in the context of evolution of biological populations, mathematical models in physiology and medicine, such as oncogenesis and spread of infections and diseases, economical sciences, analysis of signals. Concerning VIEs based models, the following books and review papers contain sections devoted to this subject in the physical and biological sciences: Brunner, Agarwal and O’Regan, Corduneanu and Sandberg, Zhao. Most of these also include extensive lists of references.

Abstract:
Displacement Green's function is the building block for some semi-analytical methods like Boundary Element Method (BEM), Distributed Point Source Method (DPCM), etc. In this thesis, the displacement Green`s function in anisotropic media due to a time harmonic point force is studied. Unlike the isotropic media, the Green's function in anisotropic media does not have a closed form solution. The dynamic Green's function for an anisotropic medium can be written as a summation of singular and non-singular or regular parts. The singular part, being similar to the result of static Green's function, is in the form of an integral over an oblique circular path in 3D. This integral can be evaluated either by a numerical integration technique or can be converted to a summation of algebraic terms via the calculus of residue. The other part, which is the regular part, is in the form of an integral over the surface of a unit sphere. This integral needs to be evaluated numerically and its evaluation is considerably more time consuming than the singular part. Obtaining dynamic Green's function and its spatial derivatives involves calculation of these two types of integrals. The spatial derivatives of Green's function are important in calculating quantities like stress and stain tensors. The contribution of this thesis can be divided into two parts. In the first part, different integration techniques including Gauss Quadrature, Simpson's, Chebyshev, and Lebedev integration techniques are tried out and compared for evaluation of dynamic Green’s function. In addition the solution from the residue theorem is included for the singular part. The accuracy and performance of numerical implementation is studied in detail via different numerical examples. Convergence plots are used to analyze the numerical error for both Green's function and its derivatives. The second part of contribution of this thesis relates to the mathematical derivations. As mentioned above, the regular part of dynamic Green's function, being an integral over the surface of a unit sphere, is responsible for the majority of computational time. From symmetry properties, this integration domain can be reduced to a hemisphere, but no more simplification seems to be possible for a general anisotropic medium. In this thesis, the integration domain for regular part is further reduced to a quarter of a sphere for the particular case of transversely isotropic material. This reduction proposed for the first time in this thesis nearly halves the number of integration points for the evaluation of regular part of dynamic Green's function. It significantly reduces the computational time.

Full text
Abstract:
This technical report presents the new numerical modeling capabilities for simulating wave attenuation and mean water level changes through flexible vegetation such as smooth cordgrass in coastal and marine wetlands. These capabilities were implemented into the Cross-SHORE (CSHORE) numerical model. The biomechanical properties of vegetation such as dimensions, flexibility, and bending strength are parameterized in terms of the scaling law. Correspondingly, a new formulation of the vegetation drag coefficient, CD, is developed using field data from a salt marsh in Terrebonne Bay, LA, by considering spatially varying effective stem and blade heights of species. This report also presents a general procedure for using the model to simulate hydrodynamic variables (i.e., waves, currents, mean water levels) at vegetated coasts, which are used to quantify the effects of wave attenuation and reduction of surge and runup due to vegetation. Preliminary model validation was conducted by simulating a set of laboratory experiments on synthetic vegetation, which mimicked the flexibility of Spartina alterniflora. The validation results indicate that the newly developed vegetation capabilities enable CSHORE to predict changes of wave heights and water levels through marshes by considering species-specific biomechanical features. The model is also applicable to assess vegetation effectiveness against waves and surges.

Full text
Abstract:
Employing numerical prediction models can be a powerful tool for forecasting air quality and visibility hazards related to dust events. However, these numerical models are sensitive to surface conditions. Roughness features (e.g., rocks, vegetation, furrows, etc.) that shelter or attenuate wind flow over the soil surface affect the magnitude and spatial distribution of dust emission. To aide in simulating the emission phase of dust transport, we used a previously published albedo-based drag partition parameterization to better represent the component of wind friction speed affecting the immediate soil sur-face. This report serves as a guide for integrating this parameterization into the Weather Research and Forecasting with Chemistry (WRF-Chem) model. We include the procedure for preprocessing the required input data, as well as the code modifications for the Air Force Weather Agency (AFWA) dust emission module. In addition, we provide an example demonstration of output data from a simulation of a dust event that occurred in the Southwestern United States, which incorporates use of the drag partition.

Full text
Abstract:
This paper focuses on research from the RISE Ethiopia team and addresses two major objectives: analysing the progress made towards achieving key goals under the four focus areas of GEQIP-E (internal efficiency, quality, equity, and system strengthening for policy formulation and reform) and whether the indicators of GEQIP-E implementation have been associated with estimated improvements in numeracy over one academic year. The analysis is based on longitudinal data collected as part of the RISE Ethiopia programme during the academic years 2018/19 and 2021/22, as they coincide with the implementation of GEQIP-E (GEQIP-E was disrupted by the dual shocks of COVID-19 and the violent civil conflicts that erupted in November 2020). Findings are presented under the four areas of intervention (school internal efficiency, quality, equity and system strengthening) and the final section links these areas of intervention with learning outcomes.
