Digital Signal Processing: Applications to Communications and Algebraic Coding Theories discusses the design of computationally efficient digital signal processing algorithms over finite fields and the relation of these algorithms to algebraic error-correcting codes.
The book provides chapters that cover such topics as signal processing techniques employed for modeling, synthesis, and analysis; systems of bilinear forms; efficient finite field algorithms; the design and study of long length cyclic convolutions and some preliminary results on their relation to linear codes; the study of the algebraic structure of the class of linear codes obtained from bilinear cyclic and aperiodic convolution algorithms over the finite field of interest; and the concept of a generalized hybrid Automatic- Repeat-Request (ARQ) scheme for adaptive error control in digital communication systems.

Engineers, mathematicians, and computer scientists will find the text invaluable.

Each text is highly practical and applied, and presents first principles for engineers who need to get up to speed in a new area fast. The focused facts provided in each guide will help you converse with experts in the field, attempt your own initial troubleshooting, check calculations, and solve rudimentary problems.

Dimensional Analysis provides the foundation for similitude and for up and downscaling. Aeronautical, Civil, and Mechanical Engineering have used Dimensional Analysis profitably for over one hundred years. Chemical Engineering has made limited use of it due to the complexity of chemical processes. However, Chemical Engineering can now employ Dimensional Analysis widely due to the free-for-use matrix calculators now available on the Internet. This book shows how to apply matrices to Dimensional Analysis.

• Supported by industry examples to help you solve a real world problem
• Single subject volumes provide key facts for professionals

This book deals with the modeling of food processing using dimensional analysis. When coupled to experiments and to the theory of similarity, dimensional analysis is indeed a generic, powerful and rigorous tool making it possible to understand and model complex processes for design, scale-up and /or optimization purposes.

This book presents the theoretical basis of dimensional analysis with a step by step detail of the framework for applying dimensional analysis, with chapters respectively dedicated to the extension of dimensional analysis to changing physical properties and to the use of dimensional analysis as a tool for scaling-up processes. It includes several original examples issued from the research works of the authors in the food engineering field, illustrating the conceptual approaches presented and strengthen the teaching of all.

• Discusses popular dimensional analysis for knowledge and scaling-up tools with detailed case studies
• Emphasises the processes dealing with complex materials of a multiphase nature
• Introduces the concept of chemical or material similarity and a framework for analysis of the functional forms of the propoerty

La disponibilidad de nitrógeno es uno de los factores más importantes que limita el crecimiento y desarrollo de las plantas. La interacción simbiótica entre leguminosas y bacterias del suelo fijadoras de nitrógeno pertenecientes a la familia Rhizobiaceae resulta en la formación de un nuevo órgano, denominado nódulo, donde la bacteria fija el nitrógeno atmosférico (FBN) a formas reducidas que pueden ser incorporadas al metabolismo de la planta. El establecimiento de la simbiosis requiere una reprogramación de la expresión génica de las células de la raíz que involucra cambios a nivel transcripcional y postranscripcional. Dentro de estos últimos se encuentra la distribución dinámica de los mRNAs en distintos complejos ribonucleoproteicos (RNPs) citoplasmáticos, principalmente los polisomas, los cuerpos de procesamiento (P-bodies o PBs) y los gránulos de estrés (Stress Granules o SGs). En esta tesis doctoral se desarrolló una técnica de purificación de complejos RNPs en la planta leguminosa M. truncatula, que permita caracterizar el movimiento de RNAs entre los diferentes complejos RNP citoplasmáticos durante la simbiosis. La expresión de las proteínas DCP1 y RBP47 fusionadas al tag FLAG permitió co-inmunopurificar el RNA asociado a PBs y SGs, respectivamente. La cuantificación de mRNAs de genes involucrados en la vía de señalización del Nod Factor (NF) mostró que existe una regulación postranscripcional de los genes de la vía del NF en M. truncatula que depende de la movilización dinámica de RNAs entre los polisomas, los SGs y los PBs. Por otra parte, la expresión de las fusiones RBP47-RFP y DCP1-YFP permitieron visualizar la dinámica y colocalización de los RNPs in vivo en tejido foliar de N. benthamiana y de raíces de M. truncatula. En el segundo capítulo, se analizaron las características de los mRNAs que presentaban un cambio en la eficiencia traduccional en respuesta a la inoculación con rizobios. La longitud de los mRNAs, el contenido GC, y la estructura secundaria, tanto de sus secuencias no traducidas como de las codificantes, están correlacionadas con la eficiencia traduccional, sugiriendo que estos parámetros influyen en la asociación de los transcriptos a los polisomas en el contexto de la reprogramación génica y la modulación de su traducción durante la simbiosis. En el tercer capítulo, se muestra que las redes transcripcionales que operan en la simbiosis son diferentes a las que participan en la selección de aquellas cepas más eficientes en la simbiosis. Estas diferencias involucran elementos de regulación que actúan tanto a nivel transcripcional como postranscripcional. Los resultados obtenidos en este trabajo de tesis han arrojado luz sobre la dinámica citoplasmática de los mRNAs y han permitido caracterizar los elementos regulatorios del DNA y del RNA asociados a la simbiosis fijadora de nitrógeno, sentando las bases para futuros proyectos de investigación y desarrollo que permitan optimizar la fijación de nitrógeno en leguminosas de interés agronómico.

Esta tesis constituye un estudio teórico acerca de algunos aspectos fundamentales de las reacciones de alcanos utilizando zeolitas como catalizadores. El trabajo se centra especialmente en la catálisis heterogénea a nivel microscópico y está dirigido fundamentalmente a aumentar la comprensión de los aspectos mecanísticos de la conversión de hidrocarburos catalizada por sólidos ácidos. En particular se han estudiado, en el marco de la teoría de funcionales de la densidad y en el contexto de la teoría de átomos en moléculas, un grupo de carbocationes en fase gaseosa, la adsorción de metano sobre dos agregados zeolíticos y la reacción de metano y etano con dichos agregados.
