Book Description
This book presents an introduction to the Finite Element Method (FEM) and is primarily aimed at students, engineers and scientists who already know structural calculation. It starts from the matrix reformulation of the direct stiffness method to understand the enormous potential of introducing the idea of the weak formulation for the approximation of strut structure problems. The correspondence of results between the initial classical formulation and that of the FEM when using linear shape functions and Hermite polynomials, makes it possible to approach its general formulation more easily as a procedure to obtain approximate solutions of differential equations in partial derivatives. It is essential now to introduce the idea of element, which allows, from the definition of a reduced number of base functions and through a simple combination process, to approximate its real behavior and, through superposition, that of the structure.

Book Description
This text is designed for those who already know structural calculation. It starts with the simple exercise of reformulating the direct stiffness method using matrices. The aim is to allow the student to understand the enormous power and generality of the weak formulation for the approximation of strut structure problems by using a formulation which is easy to understand. The correspondence of results of the initial classical formulation with those of the FEM when using linear shape functions and Hermite polynomials allows us to tackle the general formulation of the fundamental concepts of the method more easily. Once the method and the details of its general formulation are understood (although only through its application in a specific structural type), the FEM is presented in a general way, as a procedure for obtaining approximated solutions for partial differential equations. The approaches to field problems and to linear elasticity problems are presented as examples. The method has been now clearly presented and therefore, the selection of the type of element, with the generation of interpolation functions of higher degree and their systematization in element families, can be studied in greater depth. This part finishes with the introduction of the idea of isoparametric transformation that, together with numerical integration, explains the stage of development reached by the method. Finally, the subject relative to plates is dealt with, looking at their specific use as structural elements, and trying to show the difficulty of satisfying the continuity between elements in thin plates, and the shear locking solution in thick plates amongst other things

Book Description
Análisis de la Conversación: fundamentos, metodología y alcances ofrece la primera introducción comprehensiva al Análisis de la Conversación (AC) en español y con datos conversacionales disponibles en línea. El libro está organizado en nueve capítulos. En los capítulos iniciales, se presenta el AC como una disciplina y método analítico para el estudio del habla y otras formas de conducta humana en la interacción social, se hace un breve recuento histórico del desarrollo de la perspectiva analítico-conversacional y se introduce a los lectores al sistema de transcripción usado en el AC. Los capítulos siguientes están dedicados a explorar cuatro dominios claves en la organización de la conversación espontánea: la toma de turnos, las secuencias de acciones, la preferencia y la enmienda, destacando la importancia de prácticas del diseño de turno en cada dominio. Seguidamente, se discute la conexión entre organizaciones y prácticas del habla en interacción y contextos sociales e identidades de los participantes en conversación. El libro concluye ofreciendo una serie de sugerencias para la investigación analítico-conversacional en español y señalando su relevancia para la indagación de la interacción en contextos legales, políticos, médicos, tecnológicos, entre otros. Cada capítulo incluye ejemplos tomados de conversaciones auténticas en distintas variedades de español, cuyos audios pueden ser consultados directamente en línea. Con el fin de revisar y profundizar lo aprendido, cada capítulo ofrece un apartado final con preguntas, actividades y lecturas adicionales. Como apéndices al libro, se ofrecen, además, un glosario de términos bidireccional español–inglés y un sumario con las convenciones de transcripción más usadas. Escrito enteramente en español, el libro ofrece una introducción actual, comprehensiva y amigable al AC y sus aplicaciones por lo que constituye una fuente de referencia ideal para estudiantes, instructores e investigadores en lingüística (hispánica), sociología y comunicaciones. Análisis de la Conversación provides the first comprehensive, Spanish-language introduction to the field of Conversation Analysis (CA), utilizing conversational data that is publicly available online. The book is organized in nine chapters. The opening chapters introduce Conversation Analysis as a unique theory and method to study language and other forms of conduct in social interaction. Readers are presented with a history of the development of this framework for analyzing interaction and introduced to the transcription system used in CA. The following chapters explore four key domains of organization within spontaneous conversation—turn-taking, preference, sequence, and repair—highlighting the importance of turn design practices in each. The authors then review the connection of these organizations and practices to social contexts and participant identities, and they conclude by suggesting a range of avenues for future research on Spanish conversation, including its relevance in specific legal, political, medical, and technological settings. Each chapter includes a variety of examples from authentic Spanish conversation, which readers can consult directly online. Each chapter is additionally accompanied by a set of questions and activities that allow readers to check and reinforce their understanding, as well as lists of additional readings for readers interested in more specific topics. Glossaries of technical vocabulary—both Spanish-English and English-Spanish—are included as appendices, along with a summary of transcription system notation. Written entirely in Spanish, this book presents a thorough and engaging introduction to Conversation Analysis and its applications. It is ideal for students, instructors, and researchers in Hispanic Studies, (Spanish) Linguistics, Sociology, and Communication Studies.
