Classical Numerical Methods in Scientific Computing

Partial differential equations are paramount in mathematical modelling with applications in engineering and science. The book starts with a crash course on partial differential equations in order to familiarize the reader with fundamental properties such as existence, uniqueness and possibly existing maximum principles. The main topic of the book entails the description of classical numerical methods that are used to approximate the solution of partial differential equations. The focus is on discretization methods such as the finite difference, finite volume and finite element method. The manuscript also makes a short excursion to the solution of large sets of (non)linear algebraic equations that result after application of discretization method to partial differential equations. The book treats the construction of such discretization methods, as well as some error analysis, where it is noted that the error analysis for the finite element method is merely descriptive, rather than rigorous from a mathematical point of view. The last chapters focus on time integration issues for classical time-dependent partial differential equations. After reading the book, the reader should be able to derive finite element methods, to implement the methods and to judge whether the obtained approximations are consistent with the solution to the partial differential equations. The reader will also obtain these skills for the other classical discretization methods. Acquiring such fundamental knowledge will allow the reader to continue studying more advanced methods like meshfree methods, discontinuous Galerkin methods and spectral methods for the approximation of solutions to partial differential equations.

Numerical Methods in Scientific Computing

This is a book about numerically solving partial differential equations occurring in technical and physical contexts and the authors have set themselves a more ambitious target than to just talk about the numerics. Their aim is to show the place of numerical solutions in the general modeling process and this must inevitably lead to considerations about modeling itself. Partial differential equations usually are a consequence of applying first principles to a technical or physical problem at hand. That means, that most of the time the physics also have to be taken into account especially for validation of the numerical solution obtained. This book aims especially at engineers and scientists who have ’real world’ problems. It will concern itself less with pesky mathematical detail. For the interested reader though, we have included sections on mathematical theory to provide the necessary mathematical background. Since this treatment had to be on the superficial side we have provided further reference to the literature where necessary.

Essential Mechanics - Statics and Strength of Materials with MATLAB and Octave
Copyright Year: 2020
Contributor: Venkataraman
Publisher: RIT Scholar Works
License: CC BY
Essential Mechanics - Statics and Strength of Materials with MATLAB and Octave combines two core engineering science courses - “Statics” and “Strength of Materials” - in mechanical, civil, and aerospace engineering. It weaves together various essential topics from Statics and Strength of Materials to allow discussing structural design from the very beginning. The traditional content of these courses are reordered to make it convenient to cover rigid body equilibrium and extend it to deformable body mechanics.The e-book covers the most useful topics from both courses with computational support through MATLAB/Octave. The traditional approach for engineering content is emphasized and is rigorously supported through graphics and analysis. Prior knowledge of MATLAB is not necessary. Instructions for its use in context is provided and explained. It takes advantage of the numerical, symbolic, and graphical capability of MATLAB for effective problem solving. This computational ability provides a natural procedure for What if? exploration that is important for design. The book also emphasizes graphics to understand, learn, and explore design. The idea for this book, the organization, and the flow of content is original and new. The integration of computation, and the marriage of analytical and computational skills is a new valuable experience provided by this e-book. Most importantly the book is very interactive with respect to the code as it appears along with the analysis.

The book is titled "Basic English for Teaching Korean," and its primary audience consists of Korean teachers whose native language is not English and who plan to work in an English-speaking country. Given the increasing global demand for learning the Korean language, many individuals aspire to become Korean instructors. Among these future Korean educators, there are those who lack confidence in their English speaking skills and seek guidance on effectively teaching the Korean language using clear and fluent English. They are also interested in acquiring the appropriate terminology and expressions for conveying aspects of the Korean language and culture when instructing in the classroom. Within this book, we will offer a comprehensive, step-by-step guide on how to teach the Korean language in English.

Esta investigación analiza los niveles de ansiedad-rasgo y ansiedad-estado, modificando una ansiedad-estado como un estado emocional inmediato, evolucionando en el tiempo. Mientras que la ansiedad rasgo se refiere a diferencias individuales relativamente estables en la ansiedad. Tuvo como objetivo determinar niveles de ansiedad estado - rasgo en tiempos de pandemia Covid-19 en trabajadores de Red de Salud Angaraes - Huancavelica, 2021. Metodología: investigación básica, nivel descriptivo, método analítico sintético, diseño no experimental, transaccional, descriptivo, técnica utilizada, encuesta, se utilizó Inventario Ansiedad Rasgo Estado (IDARE), se tuvo muestra de 110 trabajadores. Resultados: Concerniente a niveles de ansiedad estado, se evidencia nivel bajo 7,27%, nivel medio 41,82% y 50,91% nivel alto. Respecto a ansiedad rasgo, 6.36%, nivel bajo, 40,91 % nivel medio y el 52,73% nivel alto. Respecto al género para ansiedad estado, para femeninos 2.73% nivel bajo, 20.00% nivel medio y 30.91% nivel alto; para masculinos, 4,55% nivel bajo, 21,82% nivel medio y 20,00% nivel alto. De acuerdo con el género, ansiedad rasgo, femeninos presentan 1,82% nivel bajo, 20.00% nivel medio y 31,82% nivel alto. Género masculino presentan 4,55% nivel bajo, nivel medio 20,91% y 20,91% nivel alto. Respecto a edad, trabajadores de 21 a 30 años presentan ansiedad estado en nivel bajo (2,7%), 22,7% nivel medio, y 9,1% nivel alto; de 31 a 40 años 2,7% nivel bajo, nivel medio 13,6%, y 34,5% nivel alto. Conclusión: Los trabajadores de la Red de Salud Angaraes, presentan nivel alto de ansiedad estado 50,91%, respecto a ansiedad rasgo, presentan un nivel alto 52,73%.
