An essential and practical text for both students and teachers of AC electrical circuit analysis, this text picks up where the companion DC electric circuit analysis text leaves off. Beginning with basic sinusoidal functions, ten chapters cover topics including series, parallel, and series-parallel RLC circuits. Numerous theorems and analysis techniques are examined including superposition, Thévenin's theorem, nodal and mesh analysis, maximum power transfer and more. Other important topics include AC power, resonance, Bode plots and an introduction to three-phase systems. Each chapter begins with a set of chapter objectives and includes a summary and review questions. A total of over 500 end-of-chapter exercises are included. A companion laboratory manual is available.

Open Music Theory is a natively-online open educational resource intended to serve as the primary text and workbook for undergraduate music theory curricula. OMT2 provides not only the material for a complete traditional core undergraduate music theory sequence (fundamentals, diatonic harmony, chromatic harmony, form, 20th-century techniques), but also several other units for instructors who have diversified their curriculum, such as jazz, popular music, counterpoint, and orchestration. This version also introduces a complete workbook of assignments.
Welcome to the First Edition of an OER textbook for Penn State's CRIMJ 100 Course. This text was developed with the assistance of an Affordable Course Transformation grant from The Pennsylvania State University.

Hostile use of Unmanned Aircraft Systems (UAS) technology is on the forefront of DoD defense and offensive planners.Our Counter-UAS (C-UAS) textbook has as its primary mission to educate and train resources who will enter the UAS / C-UAS field and trust it will act as a call to arms for military and DHS planners.
Criminal Law uses a two-step process to augment learning, called the applied approach. First, after building a strong foundation from scratch, Criminal Law introduces you to crimes and defenses that have been broken down into separate components. It is so much easier to memorize and comprehend the subject matter when it is simplified this way. However, becoming proficient in the law takes more than just memorization. You must be trained to take the laws you have studied and apply them to various fact patterns. Most students are expected to do this automatically, but application must be seen, experienced, and practiced before it comes naturally. Thus the second step of the applied approach is reviewing examples of the application of law to facts after dissecting and analyzing each legal concept. Some of the examples come from cases, and some are purely fictional. All the examples are memorable, even quirky, so they will stick in your mind and be available when you need them the most (like during an exam). After a few chapters, you will notice that you no longer obsess over an explanation that doesn’t completely make sense the first time you read it—you will just skip to the example. The examples clarify the principles for you, lightening the workload significantly.
Originally developed as part of a grant from the Bill & Melinda Gates Foundation, Crop Improvement is the third book in our series originally published under the title "Plant Breeding E-learning in Africa."
This book covers basic principles in the genetic improvement of crop plants. Emphasis is placed on methods of cultivar development in self-pollinating, cross-pollinating and asexually propagating crops. Relevant examples of crop improvement research in Africa are utilized to cover factors affecting cultivar release, multiplication, and distribution of high-quality seed.
At the back of the book, you can find Applied Learning Activities, downloadable worksheets which can be adapted for classroom use.
'Decolonization and Justice: An Introductory Overview' emerged from the undergraduate students’ final assignment in JS-419 on Advanced Seminar in Criminal Justice at the University of Regina's Department of Justice Studies, Canada. This book focused on decolonization of multiple justice-related areas, such as policing, the court system, prison, restorative justice, and the studies of law and criminology. This is quite likely one of the few student-led book projects in Canada covering the range of decolonization topics. Ten student authors explored the concept of decolonization in law, policing, prison, court, mental health, transitional justice and restorative justice. We are grateful to receive funding support from the University of Regina’s OER Publishing Program Small Project Grant, which enabled us to hire a professional copy editor for the book.
The design of concurrent distributed hardware systems is a major challenge for engineers today and is bound to escalate in the future, but engineering education continues to emphasize traditional tools of logic design that are just not up to the job. For engineers tackling realistic projects, improvised attempts at synchronization across multiple clock domains have long been a fact of life. Prone to hazards and metastability, these ad hoc interfaces could well be the least trustworthy aspects of a system, and typically also the least able to benefit from any readily familiar textbook techniques of analysis or verification.
Progress in the long run depends on a change of tactics. Instead of the customary but inevitably losing battle to describe complex systems in terms of their stepwise time evolution, taking their causal relationships and handshaking protocols as a starting point cuts to the chase by putting the emphasis where it belongs. This way of thinking may call for setting aside a hard earned legacy of practice and experience, but it leads ultimately to a more robust and scalable methodology.
Delay insensitive circuits rely on local coordination and control from the ground up. The most remarkable consequence of adhering to this course is that circuits can get useful things done without any clock distribution network whatsoever. Because a handshake acknowledgment concludes each interaction among primitive components and higher level subsystems alike, a clock pulse to mark them would be superfluous. This effect can bring a welcome relief to projects whose timing infrastructure would otherwise tend to create more problems than it solves.
The theory of delay insensitive circuits is not new but has not yet attracted much attention outside of its research community. At best ignored and at worst discouraged in standard curricula, this topic until now has been accessible only by navigating a sea of conference papers and journal articles, some of them paywalled. Popular misconceptions and differing conventions about terminology and notation have posed further barriers to entry. To address this need, this book presents a unified account of delay insensitive circuits from first principles to cutting edge concepts, subject only to an undergraduate-level understanding of discrete math. In an approachable tutorial format with numerous illustrations, exercises, and over three hundred references, it guides an engineering professional or advanced student towards proficiency in this extensive field.
In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.
