Direct Energy Conversion discusses both the physics behind energy conversion processes and a wide variety of energy conversion devices. A direct energy conversion process converts one form of energy to another through a single process. The first half of this book surveys multiple devices that convert to or from electricity including piezoelectric devices, antennas, solar cells, light emitting diodes, lasers, thermoelectric devices, and batteries. In these chapters, physical effects are discussed, terminology used by engineers in the discipline is introduced, and insights into material selection is studied. The second part of this book puts concepts of energy conversion in a more abstract framework. These chapters introduce the idea of calculus of variations and illuminate relationships between energy conversion processes.

L’énergie solaire au Sénégal : un droit, des droits, une histoire

Long Description:
L’énergie solaire est une promesse de développement et de prospérité pour l’Afrique. Elle a été annoncée et expérimentée sur le continent dans un esprit de science ouverte et de « communs » technologiques et énergétiques il y a déjà près de soixante ans. Séchoirs et chauffe-eaux, pompes solaires et centrales électriques thermodynamiques : des pionniers ont développé et installé, dès la fin des années 1950, des techniques et des matériels en Afrique de l’Ouest et en particulier au Sénégal.

Le présent ouvrage, issu de deux journées d’études organisées à Dakar en mai 2016, rend compte pour la première fois, de manière particulièrement symbolique, de cette histoire et du futur de l’énergie solaire en Afrique. Il rassemble, dans une première partie, des témoignages d’acteurs et une mise en perspective sociohistorique large des politiques de l’énergie solaire en Afrique de l’Ouest sur un demi-siècle. Ce regard est complété par la réédition d’un texte de référence du professeur Abdou Moumouni Dioffo, pionnier nigérien de l’énergie solaire dès 1964.

Dans une seconde partie, cet ouvrage interroge également les prolongements actuels de l’énergie solaire en France et au Sénégal, en particulier son encadrement juridique et réglementaire. L’énergie solaire peut-elle ou doit-elle être considérée comme un « commun » ou un droit humain fondamental? Quels sont aujourd’hui les droits associés à l’énergie solaire au Sénégal? Quels enseignements tirer d’une comparaison avec le corpus juridique en la matière tel qu’il existe en France?

Associant juristes français et sénégalais, et spécialistes de la sociologie et des politiques de l’énergie, cet ouvrage se veut au final une invitation et un outil pour poursuivre les recherches sur l’histoire et le droit de l’énergie solaire en Afrique.

Une anthologie bilingue de textes - Una antología bilingüe de textos de Orlando Fals Borda (1925-2008)

Short Description:
Avec Paulo Freire, Orlando Fals Borda (1925-2008), est l’un des pères fondateurs des approches décoloniales latino-américaines en sciences sociales. Pourtant, alors que le premier est une figure familière du paysage des sciences sociales francophones, le second est quasiment inconnu. Cette anthologie francophone, la première à ce jour, propose cinq textes, publiés entre 1968 et 2003, en plus d’une conférence inédite prononcée en 1966. Elle vise à présenter la proposition épistémologique de Fals Borda d’une science latino-américaine émancipée des cadres théoriques européens et nord-américains, et orientée vers la production partagée des connaissances entre universitaires et mouvements sociaux pour favoriser la transformation de la société vers une plus grande justice sociale. Chaque texte est présenté dans sa version espagnole originale et dans sa traduction française, avec une brève mise en contexte permettant de situer celui-ci dans l’œuvre de l’auteur. Une introduction présente la thématique de l’anthologie et la trajectoire intellectuelle de Fals Borda.Junto con Paulo Freire, Orlando Fals Borda (1925-2008) fue uno de los padresfundadores de los enfoques descoloniales latinoamericanos en las ciencias sociales. Sinembargo, mientras que el primero es una figura familiar en el panorama francés de lasciencias sociales, el segundo es casi desconocido. Esta antología francófona, la primera hasta la fecha, ofrece cinco textos publicados entre 1968 y 2003, además de una conferencia inédita realizada en 1966. Su objetivo es presentar la propuesta epistemológica de Fals Borda de una ciencia latinoamericana emancipada de los marcos teóricos europeo y norteamericano, y orientada a la producción de conocimientos compartida entre los académicos y los movimientos sociales para promover la transformación de la sociedad hacia una mayor justicia social. Cada texto se presenta en su versión original en español y en su traducción al francés, con una breve contextualización que permite ubicarlo en el trabajo del autor. Una introducción presenta el tema de la antología y la trayectoria intelectual de Fals Borda.

Electromagnetics Volume 1 by Steven W. Ellingson is a 225-page, peer-reviewed open educational resource intended for electrical engineering students in the third year of a bachelor of science degree program. It is intended as a primary textbook for a one-semester first course in undergraduate engineering electromagnetics. The book employs the “transmission lines first” approach in which transmission lines are introduced using a lumped-element equivalent circuit model for a differential length of transmission line, leading to one-dimensional wage equations for voltage and current.

Elementary Differential Equations with Boundary Value Problems is written for students in science, engineering, and mathematics who have completed calculus through partial differentiation. If your syllabus includes Chapter 10 (Linear Systems of Differential Equations), your students should have some preparation in linear algebra. In writing this book I have been guided by the these principles: An elementary text should be written so the student can read it with comprehension without too much pain. I have tried to put myself in the student's place, and have chosen to err on the side of too much detail rather than not enough. An elementary text can't be better than its exercises. This text includes 2041 numbered exercises, many with several parts. They range in difficulty from routine to very challenging. An elementary text should be written in an informal but mathematically accurate way, illustrated by appropriate graphics. I have tried to formulate mathematical concepts succinctly in language that students can understand. I have minimized the number of explicitly stated theorems and defonitions, preferring to deal with concepts in a more conversational way, copiously illustrated by 299 completely worked out examples. Where appropriate, concepts and results are depicted in 188 figures

This book contains roughly three parts. The first 11 chapters discussthe JavaScript language itself. The next eight chapters are about webbrowsers and the way JavaScript is used to program them. Finally,two chapters are devoted to Node.js, another environment to programJavaScript in.Throughout the book, there are five project chapters, which describelarger example programs to give you a taste of real programming. Inorder of appearance, we will work through building an artificial life simulation,a programming language, a platform game, a paint program,and a dynamic website.
