This eBook was written as the sequel to the eBook titled DC Circuits, which was written in 2016 by Chad Davis.
This eBook covers Alternating Current (AC) circuit theory as well us a brief introduction of electronics. It is
broken up into seven modules. Module 1 covers the basic theory of AC signals. Since only DC sources are used in
the first eBook, details of AC signals such as sinusoidal waveforms (or sine waves), square waves, and triangle
waves are provided. Module 2, titled AC Circuits Math Background, covers the mathematics background needed
for solving AC circuit problems. The background material in Modules 1 and 2 are combined in Module 3 to solve
circuits with AC sources that include resistors, inductors, and capacitors (RLC circuits).

Welcome to the AC Electrical Circuit Analysis, an open educational resource (OER). The goal of this text is to introduce the theory and practical application of analysis of AC electrical circuits. It assumes familiarity with DC circuit analysis. If you have not studied DC circuit analysis, it is strongly recommended that you read the companion OER text, DC Electrical Circuit Analysis before continuing. Both texts are offered free of charge under a Creative Commons non-commercial, share-alike with attribution license. For your convenience, along with the free pdf and odt files, print copies are available at a very modest charge. Check my web sites for links.

The ACS (American Chemical Society) citation style guide uses color-coded citation examples to assist chemistry students in converting MLA and APA citations to the ACS citation style. The MLA and APA citation styles are widely used in college courses, and many students are familiar with those styles. This guide makes citation in chemistry courses simple by giving examples of frequently referenced resources.

An A-Frame Virtual Reality Programming activity for CS0 students. Part of the CUNY CS04All project.

The ALMS Framework provides a way to consider how technical choices impact the ability to engage in the 5R activities associated with OER (Open Educational Resources). This video outlines key technical considerations addressed through ALMS Framework when planning an OER project.

This OER is a free alternative to expensive Introduction to Cultural Anthropology textbooks. It includes a full textbook and several original videos, 10 "challenges" (assignments), a hub of original and found resources for teaching and learning anthropology, a “connected course” of many faculty around the world sharing instructional materials, an open course freely available to anyone online, and an emerging producer of original anthropological videos and other digital content.

APEX Calculus is a calculus textbook written for traditional college/university calculus courses. It has the look and feel of the calculus book you likely use right now (Stewart, Thomas & Finney, etc.). The explanations of new concepts is clear, written for someone who does not yet know calculus. Each section ends with an exercise set with ample problems to practice & test skills (odd answers are in the back).

This text comprises a three–volume series on Calculus. The first part covers material taught in many “Calculus 1” courses: limits, derivatives, and the basics of integration, found in Chapters 1 through 6. The second text covers material often taught in “Calculus 2”: integration and its applications, along with an introduction to sequences, series and Taylor Polynomials, found in Chapters 7 through 10. The third text covers topics common in “Calculus 3” or “Multivariable Calculus”: parametric equations, polar coordinates, vector–valued functions, and functions of more than one variable, found in Chapters 11 through 15. All three are available separately for free.

This text was written as a prequel to the APEXCalculus series, a three–volume series on Calculus. This text is not intended to fully prepare students with all of the mathematical knowledge they need to tackle Calculus, rather it is designed to review mathematical concepts that are often stumbling blocks in the Calculus sequence. It starts basic and builds to more complex topics. This text is written so that each section and topic largely stands on its own, making it a good resource for students in Calculus who are struggling with the supporting mathemathics found in Calculus courses. The topics were chosen based on experience; several instructors in the Applied Mathemathics Department at the Virginia Military Institute (VMI) compiled a list of topics that Calculus students commonly struggle with, giving the focus of this text. This allows for a more focused approach; at first glance one of the obvious differences from a standard Pre-Calculus text is its size.

This book exists primarily to support Project 677 in APSC 100 in the Faculty of Engineering at Queen’s University during the winter term of 2019. It provides a publicly visible collection of information that will help with this design project. Use of these resources elsewhere under the CC license is encouraged, but not supported. The contents of this book will grow and change over the term. Please fell free to add your comments or questions in any of the sections and I will try to address them.

Ce livre est un hommage à son travail dont la portée et le caractère précurseur nous sont plus sensibles que jamais, près d’un demi-siècle après la publication de ses articles majeurs. Puissent les jeunes d’Afrique et d’ailleurs être nombreux à suivre son exemple! À noter que les textes présentés ici (à l’exception de l’article de 1969 sur « La conférence de Nairobi » et du cahier photographique) sont aussi publiés dans l’ouvrage que j’ai co-dirigé avec Mamadou Badji Du soleil pour tous. L’énergie solaire au Sénégal : un droit, des droits, une histoire (2018, Éditions science et bien commun).

This course is designed to provide an engaging and personally relevant overview of the discipline of Abnormal Psychology. You will examine the cognitive and behavioral patterns which impair personal effectiveness and adjustment. Students will provide much of the substantive content and teaching presence in this course. Additional content has been curated from "The Noba Project (http://nobaproject.com/)" and "Abnormal Psychology: An e-text! (http://abnormalpsych.wikispaces.com/).

This adaptation comprises three chapters (Chapter 2 – Psychological Research, Chapter 14 – Stress, Lifestyle, and Health, Chapter 15 – Psychological Disorders) of the original text, chapters were reformatted to make the resulting product the starting point for an Abnormal Psychology course. This adaptation has not significantly altered or updated the original 2018 text.

This writer’s reference condenses and covers everything a beginning writing student needs to successfully compose college-level work, including the basics of composition, grammar, and research. It is broken down into easy-to-tackle sections, while not overloading students with more information than they need. Great for any beginning writing students or as reference for advanced students!

This text is intended for a one- or two-semester undergraduate course in abstract algebra. Traditionally, these courses have covered the theoretical aspects of groups, rings, and fields. However, with the development of computing in the last several decades, applications that involve abstract algebra and discrete mathematics have become increasingly important, and many science, engineering, and computer science students are now electing to minor in mathematics. Though theory still occupies a central role in the subject of abstract algebra and no student should go through such a course without a good notion of what a proof is, the importance of applications such as coding theory and cryptography has grown significantly.
