How does technology impact research practices in the humanities? How does digitisation shape scholarly identity? How do we negotiate trust in the digital realm? What is scholarship, what forms can it take, and how does it acquire authority?

This diverse set of essays demonstrate the importance of asking such questions, bringing together established and emerging scholars from a variety of disciplines, at a time when data is increasingly being incorporated as an input and output in humanities sources and publications. Major themes addressed include the changing nature of scholarly publishing in a digital age, the different kinds of ‘gate-keepers’ for scholarship, and the difficulties of effectively assessing the impact of digital resources. The essays bring theoretical and practical perspectives into conversation, offering readers not only comprehensive examinations of past and present discourse on digital scholarship, but tightly-focused case studies.

This timely volume illuminates the different forces underlying the shifting practices in humanities research today, with especial focus on how humanists take ownership of, and are empowered by, technology in unexpected ways. Digital Technology and the Practices of Humanities Research is essential reading for scholars, students, and general readers interested in the changing culture of research practices in the humanities, and in the future of the digital humanities on the whole.

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.

This peer-reviewed book is used for a junior level electrical engineering class at Trine University. However, it is intended not just for electrical engineers. Direct energy conversion is a fascinating topic because it does not fit neatly into a single discipline. This book also should be of interest to physicists, chemists, mechanical engineers, and other researchers interestedin an introduction to the energy conversion devices studied by scientists and engineers in other disciplines

This course introduces principles and technologies for converting heat into electricity via solid-state devices. The first part of the course discusses thermoelectric energy conversion and thermoelectric materials, thermionic energy conversion, and photovoltaics. The second part of the course discusses solar thermal technologies. Various solar heat collection systems will be reviewed, followed by an introduction to the principles of solar thermophotovoltaics and solar thermoelectrics. Spectral control techniques, which are critical for solar thermal systems, will be discussed.

Discrete mathematics is applied in many areas including the physical, engineering, and increasingly, the social sciences. This online textbook, written by mathematics and information technology professors, is aimed at students of information technology, computer science, and applied mathematics. The focus is on applying discrete math techniques from the two broad component areas of discrete math, namely combinatorics or enumerative techniques, and graph theory.

This course describes discrete mathematics, which involves processes that consist of sequences of individual steps (as compared to calculus, which describes processes that change in a continuous manner). The principal topics presented in this course are logic and proof, induction and recursion, discrete probability, and finite state machines. Upon successful completion of this course, the student will be able to: Create compound statements, expressed in mathematical symbols or in English, to determine the truth or falseness of compound statements and to use the rules of inference to prove a conclusion statement from hypothesis statements by applying the rules of propositional and predicate calculus logic; Prove mathematical statements involving numbers by applying various proof methods, which are based on the rules of inference from logic; Prove the validity of sequences and series and the correctness or repeated processes by applying mathematical induction; Define and identify the terms, rules, and properties of set theory and use these as tools to support problem solving and reasoning in applications of logic, functions, number theory, sequences, counting, probability, trees and graphs, and automata; Calculate probabilities and apply counting rules; Solve recursive problems by applying knowledge of recursive sequences; Create graphs and trees to represent and help prove or disprove statements, make decisions or select from alternative choices to calculate probabilities, to document derivation steps, or to solve problems; Construct and analyze finite state automata, formal languages, and regular expressions.

This course examines the growing importance of medicine in culture, economics and politics. It uses an historical approach to examine the changing patterns of disease, the causes of morbidity and mortality, the evolution of medical theory and practice, the development of hospitals and the medical profession, the rise of the biomedical research industry, and the ethics of health care in America.

Los modelos de datos son mecanismos que permiten la abstracción y representación de un dominio, mediante un conjunto de reglas y símbolos pertenecientes a un lenguaje de modelado que es conforme al modelo. Un modelo puede definirse como la abstracción que permite representar los diferentes elementos pertenecientes a un dominio del negocio, sus relaciones y asociaciones, conforme sucedería en el mundo real.

Short Description:
Disinformation: Dealing with the Disaster provides a foundational knowledge of today’s chaotic online information environment. Readers will come to understand various concerning concepts such as information overload and fake news, while engaging in discussions about familiar online entities including trolls, bots and influencers. Each chapter culminates in an important lesson about how to begin to deal with the disaster and take meaningful steps towards becoming responsible digital citizens.

Long Description:
Disinformation: Dealing with the Disaster is an accompaniment to an online course with the same title. The first four chapters provide an overview of fundamental concepts and phenomena that have led us to our current online information environment. Chapter 1, Information Disorder, examines information and its evolution, looking briefly at historical and contemporary trends in the areas of misinformation, disinformation, online propaganda and more. Chapter 2, Information Distribution, provides a simple overview of the news industry including journalism and editing, as well as the progression of fake news–a politicized concept which is leading us into a post-truth world. Chapter 3, Information Automation, takes readers through the automatic aspects of information exploration, examining search engines, algorithms, and associated concepts. Chapter 4, Information Manipulation, explores human interactions with information, focusing on how humans share, consume, and interact with information on social media. Each chapter provides the reader with a base level of a specific literacy (information, media, digital and meta) making them better equipped to confront disinformation. The final chapter provides readers with various frameworks and tools for effectively evaluating information and suggests that readers integrate them into their online search behaviors.

Distributed algorithms are algorithms designed to run on multiple processors, without tight centralized control. In general, they are harder to design and harder to understand than single-processor sequential algorithms. Distributed algorithms are used in many practical systems, ranging from large computer networks to multiprocessor shared-memory systems. They also have a rich theory, which forms the subject matter for this course.
The core of the material will consist of basic distributed algorithms and impossibility results, as covered in Prof. Lynch’s book Distributed Algorithms. This will be supplemented by some updated material on topics such as self-stabilization, wait-free computability, and failure detectors, and some new material on scalable shared-memory concurrent programming.

This course covers abstractions and implementation techniques for the design of distributed systems. Topics include: server design, network programming, naming, storage systems, security, and fault tolerance. The assigned readings for the course are from current literature. This course is worth 6 Engineering Design Points.

Dive into Systems is a free, online textbook that serves as a gentle introduction to computer systems, computer organization, and parallel computing. The book is intended for an audience that has only a CS1 background. It guides readers through a vertical slice of a computer to develop an understanding of a variety of systems topics, including:

- how a computer runs a program, from a program expressed in a high-level language to low-level binary representation and circuits

- programming in C and Assembly, assuming a CS1 background

- introduction to operating systems and the systems costs that affect program performance (the memory hierarchy, caching, and code optimization)

- introduction to parallel computing with shared memory and pthreads

Dive into Systems is designed to be present topics in as independent manner as possible so that it can be used as a primary textbook for a wide range of introductory-level computer systems courses, or as a supplemental background textbook for upper-level courses that cover Operating Systems, Computer Architecture, Compilers, Networks, Databases, and Parallel Computing.

Short Description:
Visual depictions of the health care professions often do not include ethnoculturally diverse therapists and patients. Stock videos and photos can also be expensive, limiting access to high quality resources to those who can afford to pay. We developed an online library to house photos that depict therapists and patients from diverse backgrounds performing physiotherapy skills and engaging in healthcare-related activities. The Diversity Exchange is one way to enhance teaching and learning by integrating anti-racist and anti-oppressive pedagogy ensuring our culture and practices resist and dismantle institutional racism, rather than reproducing it.
