Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Pós-graduação em Educação Matemática - IGCE; Esta pesquisa buscou compreender quais são as dimensões envolvidas no processo de escolha dos temas dos projetos de Modelagem Matemática, quando os alunos são os responsáveis por essa tomada de decisão. O estudo foi desenvolvido com alunos do primeiro ano do curso de Ciências Biológicas da Unesp, campus de Rio Claro, na disciplina Matemática Aplicada, onde uma das vertentes da disciplina era a Modelagem Matemática. Fizemos uso da metodologia de pesquisa qualitativa utilizando procedimentos de observação não estruturada, análise documental das versões entregues pelos alunos, filmagem das aulas nos momentos destinados à Modelagem, dos encontros extra-classe e das entrevistas feitas após a apresentação oral do trabalho com cada grupo. Esses procedimentos nos permitiram levantar, a partir, principalmente, da fala dos alunos, dimensões que apontam o motivo desta escolha. As dimensões são: “pessoal”; “sócio-crítica”; ”palavra do professor” e “matemática”. Tais dimensões não são auto-excludentes e nem únicas. É possível que temas diferentes se encaixem em algumas das dimensões já levantadas ou que novas dimensões sejam criadas. Sendo assim...

In this article, we address online distance mathematics education research and practice in Brazil, which are relative newcomers to the educational scene. We present the national context of education in Brazil, highlighting the organization of the educational system, and also a summary of national legislation on distance education and an overview of digital inclusion in the country. We outline the potential and relevance of distance education for the Brazilian educational system and show how it could intervene in the system. With respect to research and practice in online mathematics education, we present support for research, examples of studies and highlight different aspects being addressed, including its essential components. In addition, we discuss the synergy between distance education and teacher education, and mathematics distance education and modeling, as well as other initiatives in the national scenario.

This article presents a statistical theory for texture modeling. This theory combines filtering theory and Markov random field modeling through the maximum entropy principle, and interprets and clarifies many previous concepts and methods for texture analysis and synthesis from a unified point of view. Our theory characterizes the ensemble of images (I) with the same texture appearance by a probability distribution (f(I)) on a random field, and the objective of texture modeling is to make inference about (f(I)), given a set of observed texture examples. In our theory, texture modeling consists of two steps. (1) A set of filters is selected from a general filter bank to capture features of the texture, these filters are applied to observed texture images, and the histograms of the filtered images are extracted. These histograms are estimates of the marginal distributions of (f(I)). This step is called feature extraction. (2) The maximum entropy principle is employed to derive a distribution (p(I)), which is restricted to have the same marginal distributions as those in (1). This (p(I)) is considered as an estimate of (f(I)) . This step is called feature fusion. A stepwise algorithm is proposed to choose filters from a general filter bank. The resulting model...

Background: Hantavirus pulmonary syndrome (HPS) is a life threatening disease transmitted by the rodent Oligoryzomys longicaudatus in Chile. Hantavirus outbreaks are typically small and geographically confined. Several studies have estimated risk based on spatial and temporal distribution of cases in relation to climate and environmental variables, but few have considered climatological modeling of HPS incidence for monitoring and forecasting purposes. Methodology Monthly counts of confirmed HPS cases were obtained from the Chilean Ministry of Health for 2001–2012. There were an estimated 667 confirmed HPS cases. The data suggested a seasonal trend, which appeared to correlate with changes in climatological variables such as temperature, precipitation, and humidity. We considered several Auto Regressive Integrated Moving Average (ARIMA) time-series models and regression models with ARIMA errors with one or a combination of these climate variables as covariates. We adopted an information-theoretic approach to model ranking and selection. Data from 2001–2009 were used in fitting and data from January 2010 to December 2012 were used for one-step-ahead predictions. Results: We focused on six models. In a baseline model, future HPS cases were forecasted from previous incidence; the other models included climate variables as covariates. The baseline model had a Corrected Akaike Information Criterion (AICc) of 444.98...

Recently Bruno and Vaynblat introduced a new mathematical model to describe shock induced martensitic phase transitions. This model is much simpler than prior ones -- requiring, essentially, no quantities that cannot be measured directly. Nevertheless, its predictions are in very good agreement with the experimental results. In the calculations that Bruno and Vaynblat did to match their model against experiments, they simplified the dynamics - replacing rarefaction waves by "rarefaction discontinuities". In this thesis we implement the Bruno-Vaynblat model without any such simplifications. In the process of doing this, a new numerical method for nonlinear hyperbolic conservation laws with phase transitions is developed. Furthermore, in order to improve the quantitative agreement with experiments, several extensions of the Bruno-Vaynblat model are introduced and studied. These include the addition of dissipative effects, and the introduction of a modification to the equation of state (for the Austenite phase) near the critical transition pressure.; by John Lloyd Weatherwax.; Thesis (Ph.

Solar activity, as indexed by sunspots, has a cycle of length varying from about 9 to 13 years. Statisticians have fitted several models to predict sunspot numbers one year ahead. We instead focus on predicting the magnitudes of the next cycle maximum, the next cycle minimum, the time from the initial minimum of a cycle to its maximum, called the rise time, and the time from a cycle maximum to the next cycle minimum, called the fall time. The predictions are based on sunspot numbers just far enough into a new cycle to establish that a cycle has started. We propose parsimonious regression models for the maximum and rise time. For the fall time and minimum we propose crude models, based on the sample means and variances for all past cycles. We compare our models to simulation results for many models we found in the literature including autoregressive (AR) models, subset AR (SAR) models, and related nonlinear models including a threshold AR model, transformed by squaring (TTAR model), a bilinear model, a so-called ASTAR model, and a neural network (CNAR) model. We also consider a model proposed by solar physicists, based on a functional form for cycles.; (cont.) Numerical results show that among all the models considered for sunspot numbers...

Project-based subject in which students from multiple disciplines are encouraged to develop and investigate systems and ideas from their fields of study as they explore the process of building and testing models and simulations. Explores various modeling software packages, criteria for developing the most appropriate simulation for a given situation, and methods for evaluating the success and utility of models. Students with an education focus consider what and how people learn from simulations, and how modeling tools can be implemented in public school settings. Graduate students are expected to complete additional assignments. From the course home page: Course Description During the past ten years, simulation modeling, especially as it helps people to understand complex systems, has become a mainstream use of computational technology. The widespread popularity of "edutainment" software like SimCity and Civilization gives a clear indication of the extent to which simulation games have permeated popular culture. As these and other games have found places in the classroom, researchers have tried to ascertain what and how students learn from these environments, and what implications this has for software and curriculum design. While it can be useful to experiment with pre-built models like SimCity...

Granular materials are common in everyday experience, but have long-resisted a complete theoretical description. Here, we consider the regime of slow, dense granular flow, for which there is no general model, representing a considerable hurdle to industry, where grains and powders must frequently be manipulated. Much of the complexity of modeling granular materials stems from the discreteness of the constituent particles, and a key theme of this work has been the connection of the microscopic particle motion to a bulk continuum description. This led to development of the "spot model", which provides a microscopic mechanism for particle rearrangement in dense granular flow, by breaking down the motion into correlated group displacements on a mesoscopic length scale. The spot model can be used as the basis of a multiscale simulation technique which can accurately reproduce the flow in a large-scale discrete element simulation of granular drainage, at a fraction of the computational cost. In addition, the simulation can also successfully track microscopic packing signatures, making it one of the first models of a flowing random packing. To extend to situations other than drainage ultimately requires a treatment of material properties...

The objective of this study was to investigate the performance of students when exposed to complementary activities of computational modeling in the learning of Physics and Mathematics taken integrated, using the software Modellus. The difficulties of changing record (algebraic, numeric, graphic and animation), in the work with contents of Kinematics and Functions were the subjects chosen. The study involved first-year students of high school from Agrotécnica Federal de Satuba School - AL and was held in the second half of 2008. For research was adopted a quasi-experimental design, consisting of an experimental group of 18 students who were submitted to computational modeling activities exploratory and of creation for an interval of two weeks (five meetings of two sessions of 50 minutes each) and by a control group of eighteen other students. The results show that there was a statistically significant improvement in the students performance in the experimental group when compared to students in the control group exposed only to the traditional method of teaching. The results of qualitative analysis suggest that many students achieved significant learning. Our observations suggest that the interactions between students and computer activities became a motivating factor in learning.; O objetivo deste trabalho foi o de investigar o desempenho de estudantes quando expostos a atividades complementares de modelagem computacional na aprendizagem de conteúdos de Física e de Matemática tomados de forma integracionista...

Thesis (Ph.D.) - Indiana University, Geological Sciences, 2011; Modeling natural processes is one of the most effective ways to test the plausibility of multiple hypotheses. Numerical experiments can be set to assess different scenarios that may be responsible for development of a certain phenomenon. Reaction-Transport Modeling (RTM) is a numerical approach that permits tracking multiple species simultaneously. This can be done as a system evolves spatially and temporally. RTM was applied to understanding the mechanism under which calcite mega-concretions form. The studied geological formation was the Sierra Ladrones in the Rio Grande Rift, Albuquerque Basin near Socorro, New Mexico. Initial results of the mega-concretion study were not insightful concerning cementation mechanisms despite numerical representations of the reactions based on measured groundwater characteristics, so this project was not pursued further. Stratigraphic-Forward Modeling (SFM) is a technique that allows for testing how stratal architecture evolves through time and space. A series of numerical experiments were set up to assess the effects of distance to sediment source and seasonally varying discharge on fluvial processes in a tropical paleoclimate. Post-depositional processes...

Approved for public release; distribution is unlimited; Mathematical modeling forms a bridge between the study of mathematics and the application of mathematics with the intent of explaining or predicting real world behavior. In their book A First Course in Mathematical Modeling, Frank R. Giordano, Maurice D. Weir, and William P. Fox provide an introduction to the entire modeling process. Model verification, an important step(in the modeling process, often requires the analysis of vast amounts of data, making computational support essential. Mathematical Modeling Using MA MATLAB acts as a companion resource to A First Course in Mathematical Modeling with the goal of guiding the reader to a fuller understanding of the modeling process through the employment of MATLAB's powerful computational capabilities. In it, the reader is led through a series of examples, each building upon the previous, which apply MATLAB's computational power to various modeling scenarios. While not intended as a text in modeling, Mathematical Modeling Using MA TIAB is a useful resource for the novice modeler interested in tackling problems too large to be performed manually; http://www.archive.org/details/mathematicalmode00phil; Captain, United States Army

All fluid dynamic equations are valid in their modeling scales, such as the kinetic scale for the Boltzmann equation and the hydrodynamic scale for the Navier-Stokes (NS) equations. There is no such an equation which is valid in all scales. With the variation of the modeling scales, there should have a continuum spectrum of fluid dynamic equations, instead of the a few well-defined ones. The unified gas-kinetic scheme (UGKS) is a direct modeling method, and its modeling scale is the mesh size and time step. With the variation of the ratio between the numerical cell size and local particle mean free path, the UGKS covers flow physics from the kinetic scale particle transport and collision to the hydrodynamic scale wave propagation. Even with past success, the modeling in UGKS is mainly based on the time evolution of kinetic model equations. In the kinetic regime there is still dynamic difference between the kinetic collision model and the full Boltzmann collision term. This work is about the further development of the UGKS by implementing the full Boltzmann collision term in the regime needed, and to construct an accurate and efficient UGKS in all flow regimes. The central ingredient of the finite volume UGKS is the coupled particle transport and collision in the flux evaluation across a cell interface. The molecular free transport and the hydrodynamic NS gas evolution become two limiting solutions in the flux modeling. The UGKS has the asymptotic preserving property of recovering the NS solutions in the continuum flow regime...

The Immersed Boundary (IB) method is a widely-used numerical methodology for the simulation of fluid-structure interaction problems. The IB method utilizes an Eulerian discretization for the fluid equations of motion while maintaining a Lagrangian representation of structural objects. Operators are defined for transmitting information (forces and velocities) between these two representations. Most IB simulations represent their structures with piecewise-linear approximations and utilize Hookean spring models to approximate structural forces. Our specific motivation is the modeling of platelets in hemodynamic flows. In this paper, we study two alternative representations - radial basis functions (RBFs) and Fourier-based (trigonometric polynomials and spherical harmonics) representations - for the modeling of platelets in two and three dimensions within the IB framework, and compare our results with the traditional piecewise-linear approximation methodology. For different representative shapes, we examine the geometric modeling errors (position and normal vectors), force computation errors, and computational cost and provide an engineering trade-off strategy for when and why one might select to employ these different representations.; Comment: 33 pages...

This is a Research and Instructional Development Project from the U. S. Naval Academy. In this monograph, the basic methods of nonstandard analysis for n-dimensional Euclidean spaces are presented. Specific rules are deveoped and these methods and rules are applied to rigorous integral and differential modeling. The topics include Robinson infinitesimals, limited and infinite numbers; convergence theory, continuity, *-transfer, internal definition, hyprefinite summation, Riemann-Stieltjes integration over Jordan-measurable regions; modeling with integrals via Infinite Sum Theorems; the nonstandard integral modeling rules - the method of constants, the methods of max. and min., and the hyperfinite sum; pure infinitesimal integral modeling via geometric elements; microgeometry, line and surface integrals, gauge integrals, fluxions and their relations to dynamic geometry. These rigorous results are also applied to lengths of curves, areas and volumes for Jordan-measurable regions, incompressible fluids, moments of inertia, electric field vectors, force fields and very elementary physics. Also presented are rigorous differential derivations for the partial differential equations for internal heat transfer and the vibrating membrane. All results are rigorously established and...

A hallmark of engineering design is the use of models to explore the consequences of design decisions. Sometimes these models are physical prototypes or informal drawings, but the sine qua non of contemporary practice is the use of formal, mathematical models of system structure and behavior. Whether circuit models in electrical engineering, heat-transfer models in mechanical engineering, or queuing theory models in industrial engineering, mathematics makes it possible to perform rigorous analysis that is the cornerstone of modern engineering. Until recently, such modeling was impractical for software systems. Informal models abounded, such as those created in UML1, but rigorous models from which one could derive significant properties were either so rudimentary or so tedious to use that it was difficult to justify the incremental benefit in other than the most critical of systems. In part this is a reflection of the relative immaturity of software engineering, but it also reflects a key distinction between software and traditional engineering: whereas the latter builds on numerical computation and continuous functions, software is more appropriately modeled using logic, set theory, and other aspects of discrete mathematics. Most of the models stress relationships between software components...
